Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Below in conjunction with accompanying drawing a kind of carrier sensing method and the device that the embodiment of the invention provides is described in detail.
As shown in Figure 2, a kind of carrier sensing method that provides for the embodiment of the invention; This method comprises:
201: determine that one is formed carrier wave as monitoring carrier wave; A described definite composition carrier wave has four kinds of modes as monitoring carrier wave: first kind of mode can be that UE distributes monitoring carrier wave by base station eNodeB; The second way can be selected one as monitoring carrier wave by UE self from many groups carrier wave; The third mode is that UE can hold consultation with the base station and selects the mode of monitoring carrier wave; The 4th kind of mode can be that UE selects monitoring carrier wave by MME.Wherein, it can be the algorithm that UE and base station consult in advance that the mode of monitoring carrier wave is selected in described negotiation, and UE can go out the relevant information of its monitoring carrier wave by this algorithm computation; The mode of monitoring carrier wave is selected in described negotiation, also can be that UE and base station consult to monitor the minimum carrier wave of all carrier wave medium frequencys in advance, and just that frequency is minimum carrier wave is as monitoring carrier wave.
202: when subscriber equipment is in idle condition, monitor described definite monitoring carrier wave.
It should be noted that, when adopting first kind to determine monitoring carrier wave with the second way, need the system message of UE according to Current Serving BTS and the transmission of neighbours base station, judge whether Current Serving BTS is identical with the configuration of neighbours' base station carrier, that is to say, when UE carries out cell selecting/gravity treatment, need UE to judge whether the carrier wave of selected neighbours base station comprises the current composition carrier wave of monitoring in disposing, if do not comprise, then UE needs more new technological process of trigger position, makes UE can reselect definite monitoring carrier wave.
A kind of carrier sensing method that the embodiment of the invention provides is by determining that a conduct in a plurality of composition carrier waves of LTE-Advanced system is a monitoring carrier wave; When subscriber equipment during, only monitor described definite monitoring carrier wave, thereby reduce the monitoring power consumption of subscriber equipment greatly in idle condition.In prior art, subscriber equipment is when idle condition, and all carrier waves are compared in the needs monitoring LTE-Advanced system, and subscriber equipment of the present invention only need be monitored a monitoring carrier wave, thereby make power consumption of user equipment reduce greatly, increased the stand-by time of subscriber equipment.
As shown in Figure 3, a kind of carrier sensing method that provides for the embodiment of the invention; This method is that UE distribution carrier wave to be monitored is a monitoring carrier wave by eNodeB.Its concrete realization flow is as described below:
301, when UE from Active (activation) state during to Idle (free time) state-transition, eNodeB is that UE selects a carrier wave to enter monitoring carrier wave behind the Idle state as UE; Utilize RRC (RadioResource Control, Radio Resource control) connection release (release of Radio Resource control connection) message with described monitoring carrier wave information notice UE then.Wherein, described monitoring carrier wave information can be meant the sequence number of this monitoring carrier wave or the frequency information of this monitoring carrier wave; Wherein, the LTE-A system is numbered all composition carrier waves or current available composition carrier wave, and perhaps an eNodeB is numbered its composition carrier wave, is selected as the composition carrier index of monitoring carrier wave, is called the sequence number of described monitoring carrier wave.In the system broadcast message of LTE-A system, can broadcast the numbering of described each composition carrier wave.
It should be noted that, eNodeB can also pass through MAC (Medium Access Control, the medium access control) control PDU (Protocol Data Unit, protocol Data Unit) or other signalings for example: physical layer signaling sends to UE with described monitoring carrier wave information.When UE received the RRC message of carrying monitoring carrier wave information or other signalings of carrying described monitoring carrier wave, UE stored described monitoring carrier wave information; Monitor described monitoring carrier wave.
It is also to be noted that described monitoring carrier wave information also can be carried in idle Mode Mobility Control Info (idle mode mobility control information) field in the RRC connection release message and send to UE.
302, eNodeB sends it for the selected monitoring carrier wave information of UE to network side entity; If described network side entity is MME (Mobile management entity, a Mobility Management Entity), then MME arrives this monitoring carrier wave information stores in MM (Mobile Management, the mobile management) context.
It should be noted that described network side entity can be MME or paging controller etc.
303, when network side entity has service needed paging UE, MME or the paging controller eNodeBs in TAs (Tracking Area (s), tracking area) sends PAGING (beep-page message), and this message is carried the carrier information that UE is monitoring.Wherein, described eNodeBs is meant at least one base station in the tracking area.
It is also to be noted that, when not carrying monitoring carrier wave information or eNodeBs in the PAGING message that eNodeBs finds to receive and know that the UE that needs paging is the UE of LTE system, eNodeBs sends the indication information of beep-page message on the composition carrier wave that its all LTE UE can use, this indication is used to notify the carrier wave of UE paging receiving message; Particularly, can send paging indication information by the PDCCH channel.Then, eNodeBs sends beep-page message to UE on the composition carrier wave that all LTE UE can use.Perhaps, eNodeBs sends the beep-page message indication information on the composition carrier wave that its all LTE UE can use, notice UE paging receiving message, and be included as the information of the composition carrier wave of the specific paging receiving message that UE distributes in this paging indication information.Then, eNodeB sends beep-page message on described specific composition carrier wave, and UE above-mentioned paging indication information of paging receiving message on described specific composition carrier wave can send by the PDCCH channel.
304, eNodeB notifies UE paging receiving message on the PDCCH of UE monitoring carrier wave (Physical Downlink ControlChannel, Physical Downlink Control Channel) channel, and sends beep-page message to UE on described monitoring carrier wave.
It should be noted that eNodeB also can need form paging receiving message on the carrier wave at which at notice UE on the monitoring carrier wave, then, eNodeB is transferred to UE with the beep-page message scheduling on this composition carrier wave.
A kind of carrier sensing method that the embodiment of the invention provides determines that by the base station conduct in a plurality of composition carrier waves of LTE-Advanced system is a monitoring carrier wave; When subscriber equipment during, only monitor described definite monitoring carrier wave, thereby reduce the monitoring power consumption of subscriber equipment greatly in idle condition.In prior art, subscriber equipment is when idle condition, and all carrier waves are compared in the needs monitoring LTE-Advanced system, and subscriber equipment of the present invention only need be monitored a monitoring carrier wave, thereby make power consumption of user equipment reduce greatly, increased the stand-by time of subscriber equipment.Meanwhile, the base station can also be by sending beep-page message on the composition carrier wave of appointment or on definite monitoring carrier wave, thereby saved the interface-free resources between subscriber equipment and base station greatly, improved the utilance of system.
As shown in Figure 4, be the another kind of carrier sensing method that the embodiment of the invention provides, this method is selected one by UE self and is formed carrier wave as the monitoring carrier wave under its Idle state.Its concrete realization flow is as described below:
401, UE selects a composition carrier wave to enter the monitoring carrier wave of monitoring behind the Idle state as it from a plurality of composition carrier waves; UE sends selected monitoring carrier wave information to current service eNodeB;
402, after eNodeB receives the monitoring carrier wave information that UE selects, if the composition carrier wave that eNodeB confirms UE is selected as monitoring carrier wave, then eNodeB sends monitoring carrier wave validation of information message to UE; It should be noted that if consulting with the selected composition carrier wave of UE between UE and the eNodeB in advance is monitoring carrier wave promptly composition carrier wave that UE is selected can be given tacit consent to as monitoring carrier wave by system, then eNodeB can not send the affirmation message of described monitoring carrier wave information.Meanwhile, eNodeB sends described monitoring carrier wave information to network side entity MME; MME should form carrier information and store in the MM context.
403, when network side entity has service needed paging UE, MME or the paging controller eNodeBs in TAs sends PAGING message, and this message is carried the composition carrier information that UE is monitoring.
It is also to be noted that, when not carrying monitoring carrier wave information or eNodeBs in the PAGING message that eNodeBs finds to receive and know that the UE that needs paging is the UE of LTE system, eNodeBs sends the indication information that passes beep-page message on the carrier wave that its all LTE UE can use, this indication information is used to notify the composition carrier wave of UE paging receiving message; Particularly, can send paging indication information by the PDCCH channel.Then, eNodeBs sends beep-page message to UE on the composition carrier wave that all LTE UE can use.Perhaps, eNodeBs sends the beep-page message indication information on the composition carrier wave that its all LTE UE can use, notice UE paging receiving message, and be included as the information of the composition carrier wave of the specific paging receiving message that UE distributes in this paging indication information; Then, eNodeB sends beep-page message on described specific composition carrier wave, and UE is paging receiving message on described specific composition carrier wave, and above-mentioned paging indication information can send by the PDCCH channel.
404, eNodeB notifies UE paging receiving message on the PDCCH of UE monitoring carrier wave (Physical Downlink ControlChannel, Physical Downlink Control Channel) channel, and sends beep-page message to UE on described monitoring carrier wave.
It should be noted that eNodeB also can need form paging receiving message on the carrier wave at which at notice UE on the monitoring carrier wave, then, eNodeB is transferred to UE with the beep-page message scheduling on this composition carrier wave.
A kind of carrier sensing method that the embodiment of the invention provides determines that by the base station conduct in a plurality of composition carrier waves of LTE-Advanced system is a monitoring carrier wave; When subscriber equipment during, only monitor described definite monitoring carrier wave, thereby reduce the monitoring power consumption of subscriber equipment greatly in idle condition.In prior art, subscriber equipment is when idle condition, and all carrier waves are compared in the needs monitoring LTE-Advanced system, and subscriber equipment of the present invention only need be monitored a monitoring carrier wave, thereby make power consumption of user equipment reduce greatly, increased the stand-by time of subscriber equipment.Meanwhile, the base station can also be by sending beep-page message on the composition carrier wave of appointment or on definite monitoring carrier wave, thereby saved the interface-free resources between subscriber equipment and base station greatly, improved the utilance of system.
It is also to be noted that, save the UE power consumption, increase the purpose of UE stand-by time in order to reach.The embodiment of the invention also provides a kind of carrier sensing method as shown in Figure 5, and this method is selected monitoring carrier wave by UE, monitors on this composition carrier wave.When network side entity had service needed paging UE, the eNodeBs of network side entity in TAs sent beep-page message; When eNodeB had service needed paging UE, eNodeB sent the beep-page message indication information on the composition carrier wave of all or part, sent out beep-page message on one or more composition carrier waves.Wherein, described part composition carrier wave is meant the composition carrier wave that subscriber equipment can be used; Its specific implementation process is as follows:
501:UE selects one arbitrarily as the monitoring carrier wave under its Idle pattern from a plurality of composition carrier waves;
502, when network side entity has service needed paging UE, MME or the paging controller eNodeBs in TAs sends PAGING message.Can select, this PAGING message is carried the composition carrier wave receiving ability information of paged UE.Here this UE of composition carrier wave receiving ability information representation of so-called UE can receive the composition carrier wave of which frequency range.This information can be on UE once RRC connect when discharging and report to network side entity by service eNodeB, as MME or paging controller.
503, eNodeBs is when receiving the PAGING message of MME or paging controller transmission, and the eNodeBs in this TAs sends paging indication information to UE on its whole composition carrier wave, notice UE paging receiving message.Perhaps eNodeBs judges the carrier wave receiving ability of current UE according to the ability information of UE, and sends paging indication information to UE on the composition carrier wave that UE can receive based on this ability information.Particularly, eNodeBs can send paging indication information on its PDCCH channel.Then, these eNodeBs send beep-page message to UE on its all or part composition carrier wave of (referring to the composition carrier wave that UE can use in all composition carrier waves).For example, the 20M that it is 2GHz that the 20M that the composition carrier wave of eNodeB is 800MHz by 2 frequencies forms carrier wave and two frequencies forms carrier wave and forms jointly, then when UE only has the ability of composition carrier wave of the frequency that receives 800MHz, eNodeBs just only needs 2 at 800MHz to form on the carrier waves when sending paging indication information and beep-page message to send.
Perhaps eNodeBs paging indication information on the composition carrier wave of its all or part (refer to all form the composition carrier wave that UE can use in carrier waves) is given UE, and is included as the information of the composition carrier wave of the specific paging receiving message that UE distributes in this paging indication information.ENodeBs only sends beep-page message on selected composition carrier wave then, and UE preserves the information of the specific composition carrier wave of indicating in the paging indication information, and on this specific composition carrier wave paging receiving message.
In the process that UE moves, when UE carries out in the process of cell selecting/gravity treatment, when finding that the current composition carrier wave of monitoring of UE does not exist in neighbours eNodeB, UE is for the above-described composition carrier sense of realization that can be correct, need carry out position new technological process more as shown in Figure 6;
For example: when UE when the hot spot region of 5x20M moves to the normal areas of 3x20M, the monitoring carrier wave that UE monitors in the hot spot region does not exist under common regional eNodeB.At this moment, UE need trigger the position updating process of UE, reselects new monitoring carrier wave.The eNodeB1 that focus covers disposes 5 and forms carrier wave.And the eNodeB2 of normal areas disposes 3 composition carrier waves.Like this, when UE when eNodeB1 enters the coverage of eNodeB2, the monitoring carrier wave of monitoring under eNodeB1 does not exist at eNodeB2, then this moment, UE need carry out the position to be upgraded, and reselects monitoring carrier wave.Its specific implementation process is as follows:
601:UE receives the system message of current eNodeB and neighbours eNodeB;
602:, judge whether current eNodeB is identical with the composition carrier wave configuration of neighbours eNodeB according to the described system message that receives;
603: if the configuration of the carrier wave of described current eNodeB and neighbours eNodeB is inequality, and current monitoring carrier wave does not exist in the composition carrier wave of neighbours eNodeB, when perhaps UE monitored less than current monitoring carrier wave in continuous time T under selected eNodeB, this moment, UE needed trigger position TA renewal process.
As shown in Figure 7, the another kind of carrier sensing method that provides for the embodiment of the invention, this method, is selected one by UE self and is formed carrier wave as the monitoring carrier wave under its Idle state when UE enters the Idle state by the algorithm that UE and eNodeB consult monitoring carrier wave in advance.When eNodeB received the beep-page message of network side entity transmission, eNodeB self can be according to selecting one to form carrier wave as the monitoring carrier wave of UE under the Idle state with the algorithm of UE negotiation; Below be concrete implementation process:
UE utilizes algorithm to obtain monitoring carrier wave information; Wherein said UE obtains monitoring carrier wave information and can obtain by following algorithm: monitoring carrier wave sequence number (monitoring carrier wave ID)=(UE indications) mod (number of the number of descending composition carrier wave or current available descending composition carrier wave); Wherein, described UE identifier can be any sequence number that can represent this UE, such as IMSI (International Mobile SubscriberIdentity, international mobile subscriber identifier) etc.Herein, the identifier of UE is the UE identifier in the UE context that MME preserved.For this reason, eNodeB need broadcast its number of forming carrier wave in its system message.
701, when network side entity has service needed paging UE, network side entity MME or the paging controller eNodeBs in TAs sends PAGING message.
702, when eNodeBs when receiving the PAGING message that MME sends, eNodeBs is according to algorithm: monitoring carrier wave ID=(UE identifier) mod (number of the number of descending composition carrier wave or current available descending composition carrier wave) decision sends the composition carrier wave of paging indication information and beep-page message;
703, eNodeBs on the composition carrier wave that is calculated, send notice UE paging receiving message indication information to UE, eNodeBs sends beep-page message to UE on described monitoring carrier wave then.The indication information of above-mentioned beep-page message can send at the PDCCH channel.
In addition, eNodeBs knows when the UE that needs paging is the UE of LTE system that eNodeBs sends notice UE beep-page message indication information on the composition carrier wave that its all LTE UE can use, particularly, can send paging indication information by the PDCCH channel.On the composition carrier wave that all LTE UE can use, send beep-page message then to UE.Perhaps eNodeBs sends the beep-page message indication information on the composition carrier wave that its all LTE UE can use, be included as the information of the composition carrier wave of the specific paging receiving message that UE distributes in this paging indication information, eNodeB sends beep-page message on selected specific composition carrier wave then, UE is paging receiving message on this specific composition carrier wave, and above-mentioned paging indication information can send by the PDCCH channel.
A kind of carrier sensing method that the embodiment of the invention provides, subscriber equipment and base station determine that by algorithm a conduct in a plurality of composition carrier waves of LTE-Advanced system is a monitoring carrier wave; When subscriber equipment during, only monitor described definite monitoring carrier wave, thereby reduce the monitoring power consumption of subscriber equipment greatly in idle condition.In prior art, subscriber equipment is when idle condition, and all carrier waves are compared in the needs monitoring LTE-Advanced system, and subscriber equipment of the present invention only need be monitored a monitoring carrier wave, thereby make power consumption of user equipment reduce greatly, increased the stand-by time of subscriber equipment.Meanwhile, the base station can also be by sending beep-page message on the composition carrier wave of appointment or on definite monitoring carrier wave, thereby saved the interface-free resources between subscriber equipment and base station greatly, improved the utilance of system.
As shown in Figure 8, the another kind of carrier sensing method that provides for the embodiment of the invention, this method by UE and eNodeB consult acquiescence LTE-A system all to form the individual composition carrier wave of N in the carrier wave (N=1...M, wherein M is the composition carrier wave number of eNodeB) be the monitoring carrier wave that UE monitors under the Idle state.ENodeB broadcasts its information of forming carrier wave in its system message, the information of described composition carrier wave comprises the number of forming carrier wave and/or forms carrier index.When eNodeB needed paging UE, eNodeB sent beep-page message on its N composition carrier wave.
The monitoring carrier wave that composition carrier wave that preferably can frequency is minimum or the highest is monitored under the Idle state as UE.Its concrete realization flow is as described below:
801, when UE from the Active state behind the idle state, UE monitors the minimum or the highest composition carrier wave of all carrier wave medium frequencys; For this reason, in the system message that eNodeB sends, eNodeB should broadcast to minimum or the highest composition carrier information or the sequence number of all carrier wave medium frequencys of major general;
802, when UE when the idle state is moved to other sub-districts, based on the measurement mechanism of neighbours eNodeB, UE reads the system message of this neighbours eNodeB;
803, UE confirms according to the system message that receives whether the composition carrier wave that current eNodeB monitors down also is the minimum or the highest carrier wave of frequency under this neighbours eNodeB; In this way, then continue to monitor this carrier wave; If not,, switch on the carrier wave of new minimum or highest frequency, monitor this carrier wave then according to the carrier information of the minimum or highest frequency of indicating in the system message;
It should be noted that when eNodeB needs paging UE eNodeB sends beep-page message on the minimum or the highest carrier wave of its carrier wave medium frequency.
It is also to be noted that, eNodeBs is known when the UE that needs paging is the UE of LTE system, eNodeBs sends the beep-page message indication information on the carrier wave that its all LTE UE can use, this indication is used to notify the carrier wave of UE paging receiving message, particularly, can send paging indication information by the PDCCH channel; Then, eNodeBs sends beep-page message to UE on the carrier wave that all LTE UE can use.Perhaps, eNodeBs sends the beep-page message indication information on the carrier wave that its all LTE UE can use, notice UE paging receiving message, and in this paging indication information, be included as the information of the composition carrier wave of the specific paging receiving message that UE distributes; Then, eNodeB sends beep-page message on described particular carrier wave, and UE is paging receiving message on this specific composition carrier wave, and above-mentioned paging indication information can send by the PDCCH channel.
A kind of carrier sensing method that the embodiment of the invention provides is a monitoring carrier wave by a conduct that pre-determines in a plurality of composition carrier waves of LTE-Advanced system; When subscriber equipment during, only monitor described definite monitoring carrier wave, thereby reduce the monitoring power consumption of subscriber equipment greatly in idle condition.In prior art, subscriber equipment is when idle condition, and all carrier waves are compared in the needs monitoring LTE-Advanced system, and subscriber equipment of the present invention only need be monitored a monitoring carrier wave, thereby make power consumption of user equipment reduce greatly, increased the stand-by time of subscriber equipment.Meanwhile, the base station can also be by sending beep-page message on the composition carrier wave of appointment or on definite monitoring carrier wave, thereby saved the interface-free resources between subscriber equipment and base station greatly, improved the utilance of system.
To save the UE power consumption in order reaching, to increase the purpose of UE stand-by time, also form the load of carrier wave simultaneously for balanced each.The embodiment of the invention also provides a kind of carrier sensing method as shown in Figure 9, and this method is monitored on this carrier wave by the monitoring carrier wave of system configuration main carrier/engine carrier wave as UE.When network side entity had service needed paging UE, the eNodeBs of network side entity in TAs sent beep-page message; ENodeBs then sends paging indication information on main carrier/engine carrier wave, send beep-page message on main carrier or other carrier waves.Its specific implementation process is as follows:
901, eNodeB broadcasts the information of its main carrier/engine carrier wave in the system message of its broadcasting;
902, under the Idle pattern, UE obtains the information of the main carrier of eNodeB by system message, monitors main carrier/engine carrier wave;
903, when network side entity has service needed paging UE, MME or the paging controller eNodeBs in TAs sends PAGING message.
904, the eNodeBs in the TAs is when receiving the PAGING message of MME or paging controller transmission, and eNodeBs sends paging indication information to UE on its main carrier/engine carrier wave, notice UE paging receiving message.Particularly, eNodeBs sends paging indication information on its PDCCH channel.And comprise eNodeB in this paging indication information and be the information of the composition carrier wave of the specific paging receiving message that UE distributes.ENodeBs only sends beep-page message on this specific composition carrier wave then, and UE preserves the information of the specific composition carrier wave of indicating in the paging indication information, and on this specific composition carrier wave paging receiving message.This specific composition carrier wave also can be main carrier/engine carrier wave.
As shown in figure 17, a kind of carrier sensing method that provides for the embodiment of the invention; This method is that UE distribution carrier wave to be monitored is a monitoring carrier wave by MME.When UE when enable mode enters idle pulley, under the situation about discharging for the UE context of being initiated by eNodeB, its concrete realization flow is as described below:
