Description

Mobile information processing method, base station, and mobile management device

technical field

The present application relates to communication technology, in particular to a mobile information processing method, a base station, and a mobile management device.

Background technique

In a wireless communication system such as a Long Term Evolution (Long Term Evolution, LTE) system, a user equipment (User Equipment, UE) in a connected state will perform inter-cell handover due to mobility requirements. The UE and the evolved base station (Evolved NodeB, eNodeB) serving the UE will obtain the mobility information of the UE in the connected state, and then the eNodeB will configure the relevant parameters of the UE according to the mobility information of these UEs, for example, discontinuous Reception (Discontinuous Reception, DRX) cycle, Multiple Input Multiple Output (Multiple Input Multiple Output, MIMO) parameter, measurement parameter, etc. When the UE enters the idle state from the connected state, the eNodeB will delete the mobility information of the UE in the connected state obtained by the eNodeB.

However, after the UE re-enters the connected state from the idle state, since the eNodeB has deleted the mobile information of the UE in the connected state obtained by the eNodeB, the eNodeB cannot obtain the mobile information of the UE in the connected state. Similar problems exist in other wireless communication systems.

101. The base station sends mobility information that the terminal is in the first connected state to a mobility management device before the terminal enters the idle state from the first connected state.

102. When the terminal enters a second connected state from the idle state, the base station receives mobility information sent by the mobility management device that the terminal is in the first connected state.

So far, the base station can configure related parameters of the terminal according to the mobility information of the terminal in the first connection state, for example, Discontinuous Reception (DRX) cycle, Multiple Input Multiple Output (Multiple Input Multiple Output, MIMO) parameters and measurement parameters, etc.

When the terminal is in the first connected state, it may perform inter-cell handover due to mobility requirements. The terminal and the base station serving the terminal will obtain the movement information of the terminal in the first connection state, and store the movement information of the terminal in the first connection state, for example, the movement speed of the terminal, the Information such as measurement results, information about the cell where the terminal is handed over to (that is, cell identity and residence time in the cell). When the terminal enters the idle state from the first connection state, the base station deletes the stored movement information of the terminal in the first connection state.

It should be noted that the moving speed of the terminal may include but not limited to the speed of the terminal (for example, 30 kilometers per hour, etc.) and/or the speed level of the terminal (for example, fast, normal or slow, etc. ).

In 101, before the terminal enters the idle state from the first connected state, for example, when the base station determines that the terminal needs to enter the idle state, or when the base station performs radio resource control for releasing the terminal During the process of (Radio Resource Control, RRC) connection, etc., the mobility information that the terminal is in the first connection state may be sent to the mobility management device. Specifically, taking the LTE system as an example, the eNodeB may specifically send mobility information that the terminal is in the first connection state to the MME through dedicated S1 application protocol (Application Protocol, AP) signaling, for example, UE context release complete (UE CONTEXT RELEASE COMPLETE) message.

Optionally, in a possible implementation manner of this embodiment, before step 102, the base station may further send first indication information to the mobility management device, to instruct the mobility management device to send the Mobility information of the terminal in the first connected state. Specifically, taking the LTE system as an example, the eNodeB may specifically send the first indication information, for example, an initial UE message (INITIAL UE MESSAGE) to the MME through dedicated S1AP signaling.

In 102, when the terminal enters the second connection state from the idle state, for example, during the process of establishing the RRC connection of the terminal by the base station, etc., the base station may receive the terminal information sent by the mobility management device Mobility information in the first connection state. Taking the LTE system as an example, the eNodeB may specifically receive the mobility information of the UE in the first connection state sent by the MME through S1AP signaling, for example, an initial context establishment request (INITIALCONTEXT SETUPREQUEST) message.

Optionally, in a possible implementation manner of this embodiment, when the base station enters the second connection state from the idle state, the base station may further receive information sent by the terminal that the terminal is in the second connection state. Mobility information of the idle state.

Further optionally, before the base station receives the mobility information sent by the terminal that the terminal is in the idle state, the base station may further send second indication information to the terminal to indicate the The terminal sends mobility information that the terminal is in the idle state to the base station, for example, the moving speed of the terminal, the measurement results of the terminal, and the information of the cell where the terminal is handed over (ie, the cell identity and The residence time of the above-mentioned cell) and other information.

Specifically, the base station may specifically send the second indication information through high-level signaling (that is, a system broadcast message or dedicated control signaling) or a control channel.

For example, the dedicated control signaling may be a radio resource control (Radio Resource Control, RRC) message, specifically, the second indication information may be carried through an information element (Information Element, IE) in the RRC message, and the RRC message may It is an RRC message in the prior art, for example, an RRC connection reconfiguration (RRC CONNECTIONRECONFIGURATION) message, etc., which is not limited in this embodiment, and carries the second indication information by extending the IE of the existing RRC message, Or the RRC message may also be different from the existing RRC message in the prior art.

For another example, the dedicated control signaling may be a Media Access Control (MediaAccess Control, MAC) Control Element (Control Element, CE) message, and specifically, a new MAC CE message may be added to carry the second indication information.

Optionally, in a possible implementation of this embodiment, the terminal may also obtain the second indication information directly according to pre-configuration without receiving the second indication information sent by the base station, For example, agreement agreement.

For example, the control channel may be a physical downlink control channel (Physical Downlink Control Channel, PDCCH). Specifically, the terminal may receive the second indication information sent by the base station to the terminal through the PDCCH, or may also receive the second indication information sent by the base station to the group to which the terminal belongs through the PDCCH.

Further optionally, before the base station receives the mobility information sent by the terminal that the terminal is in the idle state, the base station may further send third indication information to the terminal to indicate the The terminal sends to the base station a sending condition of the mobility information that the terminal is in the idle state, and the condition may include but not limited to one or more of the following:

The speed threshold satisfied by the moving speed of the terminal, for example, is greater than or equal to the speed threshold, or may also be less than or equal to the speed threshold;

The measurement threshold satisfied by the measurement result of the terminal, for example, is greater than or equal to the measurement threshold, or may also be less than or equal to the measurement threshold; and

It should be noted that the moving speed of the terminal may include but not limited to the speed of the terminal and/or the speed level of the terminal.

It should be noted that, the method for sending the third indication information is similar to the method for sending the second indication information. For detailed description, please refer to the related content of sending the second indication information, which will not be repeated here.

Optionally, in a possible implementation of this embodiment, taking the LTE system as an example, when the terminal enters the second connected state from the idle state, the base station may further receive the mobile management device The sent tracking area (Tracking Area, TA) list of the terminal.

Further optionally, before the base station receives the TA list of the terminal sent by the mobility management device, the mobility management device may further set the TA list of the terminal according to the mobility information of the terminal.

For example, if the speed level of the terminal is slow or stationary, the mobility management device may set a TA list containing a small number of TAs, for example, the TA list only contains one tracking area identity (Tracking Area Identity, TAI), Even the TAI of the UE is configured to cover only one eNB, so that when the terminal is in an idle state, the mobility management device or the base station can quickly and accurately page the terminal, thereby saving paging signaling.

For another example, if the speed level of the terminal is fast, the mobile management device can set a TA list containing a large number of TAs. For example, the TA list contains multiple TAIs, so that the number of TAIs caused by the movement of the terminal can be reduced. The resulting TA update signaling. At the same time, when the base station needs to release some terminals due to load reasons, the base station can preferentially release terminals whose speed level is fast, thereby reducing signaling overhead caused by handover.

Optionally, in a possible implementation manner of this embodiment, after the mobility management device receives the mobility information of the terminal sent by the base station, the mobility management device may further When the validity period arrives, delete the mobility information of the terminal.

In this embodiment, before the terminal enters the idle state from the first connected state, the base station sends mobility information that the terminal is in the first connected state to the mobility management device, so that the base station can When the idle state enters the second connected state, receiving the mobility information sent by the mobility management device that the terminal is in the first connected state can solve the problem in the prior art that the base station re-enters the connected state from the idle state Afterwards, the problem that the base station cannot obtain the mobile information of the terminal in the connected state caused by deleting the mobile information of the terminal in the connected state obtained by the base station, thereby realizing that the base station obtains the mobile information of the terminal in the connected state after the terminal enters the connected state from the idle state Mobile information before the terminal is in an idle state.
