Detailed ways

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Embodiment one

This embodiment provides a method for saving energy in a cell. Referring to FIG. 1, the method for realizing the embodiment of the present invention includes the following steps:

Step S101: According to the state of the carrier frequency, it is judged whether the carrier frequency satisfies the trigger condition of shifting to the target energy-saving mode, and if so, step S102 is executed.

In this embodiment, it is first necessary to define several working modes for the carrier frequency, and each working mode corresponds to a working mode of the carrier frequency. Among them, except for the working mode in which the carrier frequency does not perform any energy saving, other working modes can be called It is an energy-saving mode, hereinafter referred to as energy-saving mode. The energy-saving degree of the carrier frequency working in different energy-saving modes is different.

For example, the following working modes can be defined for the carrier frequency:

Working mode 0: The carrier frequency in this working mode does not save energy;

Working mode 1: Including specific service restriction and specific user restriction. In order to save resource consumption, the carrier frequency in this working mode will only be able to provide specific business or provide service only to specific users. Restriction of specific services can be to restrict certain types of specific service access, such as restricting VOIP (Voice over Internet Protocol, Internet phone) services, high-speed data service access, etc.; it can also be to provide only specific services, such as only providing VOIP services, etc. Specific user restriction can be to restrict the access of specific users, such as restricting the access of low-priority users; it can also provide services only to specific users, such as providing services only to gold medal users;

Working mode 2: The carrier frequency is turned off. The carrier frequency in this working mode is completely turned off without any energy consumption.

It should be noted that in practical applications, the definition of the working mode of the carrier frequency can not only be limited to the three working modes understood above, but the specific definition of the working mode is also different, and the specific definition of the above working mode does not constitute a limitation to this article. Limitations of the Examples of the Invention.

Here, for the convenience of description, the energy saving mode to be migrated to is referred to as the target energy saving mode.

The trigger condition for migrating to the target energy-saving mode can follow one or any combination of the following principles:

1) Event trigger principle. This principle means that the shutdown of the carrier frequency is triggered by a preset event when a condition is met. For example, based on event triggering based on load information, when the load on the carrier frequency is less than or equal to the preset first threshold value, the carrier frequency is triggered to migrate to the target energy-saving mode. The load can be the PRB (Physical Resource Block, physical resource block) resource occupancy rate, the number of active users, the number of idle users, etc. within a certain period of time. The number of users in the idle state can be estimated by counting the number of user UEs that are periodically updated in the tracking area (Tracking Area, TA). The first threshold values of these events can be pre-configured through OAM (Operation and Maintenance, operation and maintenance system). The value of the first threshold is determined according to operator policies and network planning data, and is not limited in this embodiment of the present invention. For example, when the first threshold is 0, it means that when there is no load on the carrier frequency, the transfer of the carrier frequency to the target energy-saving mode is triggered. If the trigger threshold is not 0, before starting the carrier frequency migration to the target energy-saving mode, the load conditions of adjacent cells or other carrier frequencies in the same cell should also be considered. Avoid the situation that the adjacent cell/base station is overloaded after the cell/base station is closed.

2) Business trigger principle. The criterion means that the number of user UEs using a certain type of service on a carrier frequency is less than or equal to a preset load threshold within a certain period of time, which is referred to as the second threshold hereinafter. For example, when there is no LTE service on a carrier frequency in a cell of an LTE (Long Term Evolution, Long Term Evolution) system, the carrier frequency is triggered to migrate to the target energy-saving mode.

3) Periodic trigger principle. The criterion means that when the time reaches the preset time, the cell is triggered to migrate to the target energy-saving mode. The triggered period can be initially configured according to the traffic model at the network planning stage. The trigger period can also be dynamically configured during the network operation phase according to various performance indicators of the network and actual traffic statistics.

Step S102: Determine whether the above-mentioned carrier frequency can be migrated to the target mode, and if so, execute step S103.

Among them, determining whether the carrier frequency can be migrated to the target mode may specifically include the following methods:

Method 1: static configuration method. In the network deployment stage, when doing cell planning, determine whether the carrier frequency can be migrated to the target energy-saving mode according to the geographic location information of the planned cell and the coverage information of the geographic location. For example, if within the carrier frequency coverage of a certain cell, there are other cells providing inter-frequency or inter-system coverage at the same time, it is determined that the carrier frequency can be migrated to the target energy-saving mode. However, it is necessary to avoid that all the cells in the geographical location are migrated to the energy-saving mode which is completely turned off.

In practical applications, an attribute value for the carrier frequency may be maintained in advance, which may be called a relocatable attribute value, and the attribute value indicates whether the carrier frequency can be relocated to an energy-saving mode. For example, the attribute value may be configured in the base station of the corresponding cell, and configured using OAM, specifically, as shown in FIG. 2 , including:

Step S201: OAM 202 uses the configuration management (CM, Configuration Management) message of the interface between OAM 202 and base station 201 to configure the attribute value of the carrier frequency in each cell in the base station.

Step S202: The base station 201 sends a configuration response message to the OAM 202 using the configuration management message of the interface between the OAM 202 and the base station 201.

Method 2: Dynamic decision method. During network operation, it is determined whether the carrier frequency can be migrated to the target energy-saving mode according to the network operation status, carrier frequency load information, and user UE measurement reports.

In practice, the execution subject of the above judgment action may be the OAM or the base station corresponding to the cell where the carrier frequency is located. Similarly, in this method, an attribute value can also be maintained for the carrier frequency, and the attribute value indicates whether the carrier frequency can be migrated to the energy-saving mode. It is also necessary to prevent all cells in the geographical location from being migrated to a completely off energy-saving mode. The specific implementation of the dynamic decision method may be described in detail below by taking the maintenance of the above attribute value for the carrier frequency as an example. Wherein, the value range of the above attribute value can be defined as including true and false, which respectively correspond to whether the carrier frequency can be transferred to the energy-saving mode or not.

The above dynamic decision method may include: the same coverage criterion. The judgment condition of this criterion is whether there are other cells or base stations within the range covered by the carrier frequency of the cell to provide coverage of different frequencies/systems at the same time.

The specific implementation method of the same coverage principle can be one of the following or any combination:

a) The user UE measures the neighboring cells, if within a statistical period, the signal quality of at least one of the neighboring cells reported by the user UE reaches a certain threshold, for example greater than or equal to the third threshold, then Indicates that there are other cells or base stations within the range covered by the carrier frequency of the cell that provide coverage of different frequencies/systems at the same time. At this time, the base station reports this information to OAM, and OAM sets the attribute of this carrier frequency to true after confirmation; or the base station modifies it by itself properties of this carrier frequency and inform OAM.

b) Based on the existing inter-frequency/inter-system adjacent cells in the adjacent cell list in the cell, plus the comprehensive judgment of cell geographic information and coverage information. As shown in Figure 3, the decision condition for a cell A to provide the same coverage for cell B is R>r, and R>=d+r, where R is the radius of cell A, and r is the radius of cell B, satisfying the above condition, it can be considered that cell B meets the same coverage requirement, and the attribute value of cell B indicating whether the carrier frequency can be migrated to the energy-saving mode can be set to "yes".

Step S103: Migrate the carrier frequency to the target energy-saving mode.

Step S104: Notifying the terminal of the target energy-saving mode to which the carrier frequency transitions.

Wherein, the current working state of the carrier frequency in the cell is broadcast in the system broadcast message, or the user terminal UE is notified of the change of the system working state through a paging message.

After the carrier frequency is migrated to the target energy-saving mode, the adjacent nodes may also be notified of the current state information of the cell where the above carrier frequency is located.

The adjacent nodes include adjacent base stations, all MMEs (Mobility Management Entities, mobility management entities) in the pool (pool), and OAMs. The pool is a resource pool composed of multiple MMEs.

As shown in Figure 4, the specific implementation of the above notification to adjacent nodes may include:

Step S401: The base station 401 corresponding to the cell where the carrier frequency migrated to the energy-saving mode sends a base station configuration update message to the adjacent node 402 such as the adjacent base station, MME or OAM, and notifies the adjacent node 402 of the working mode after the carrier frequency switching in the cell.

In actual application, the name of the message may be different, as long as the message can complete the same or similar function, it can be used. The message carries an indication that the carrier frequency is shifted to the target energy-saving mode, or carries a cause value of the switching. The message can also carry the cell identifier where the carrier frequency is located, such as E-CGI (E-UTRANCell Global Identifier, evolved cell global identifier), CGI (Cell Global Identifier, cell global identifier), or PCI (Physical Cell Identity, physical cell ID) and other information. The message can also carry the current capability information of the cell, which includes but is not limited to: the cell's ability to support services and the cell's ability to support functions. , Mobility optimization, interference coordination, load balancing and other self-organizing network functions and wireless resource management functions. These cells are optional.

Step S402: The adjacent node 402 saves the response configuration information and performs corresponding processing. The above corresponding processing includes: updating the state of the cell in the NRT (Neighbor Relation Table, neighbor relation table) table, and recording specific state information and cell capability information, the capability information includes but not limited to the cell's ability to support services and the cell's ability to support Functional support. If the current working mode of all carrier frequencies of the cell is completely off, the adjacent node can also delete the cell. The MME records the closed cells and their status in the TA according to the notification. If all the carrier frequencies of all the cells in the TA enter into a completely closed working mode, no paging will be initiated in the TA subsequently.

Step S403: The adjacent node 402 sends a base station configuration update response message to the base station 401 corresponding to the cell where the carrier frequency transitioned to the target energy-saving mode is located. This step is optional, and the execution sequence of step S402 can be exchanged.

After the carrier frequency is migrated to the target energy-saving mode, corresponding resources or interfaces may also be released according to the definition of the target energy-saving mode.

In addition, the method provided by the embodiment of the present invention may also include a process of activating a cell carrier frequency. The activation includes migrating from an energy-saving mode to a working mode without energy-saving, and may also include migrating to an energy-saving mode with a slightly less energy-saving degree than the current energy-saving mode.

The above activation process can include the following methods:

Method 1: The idle user activates the carrier frequency of the cell. The specific implementation includes:

Implementation 1): The user in the idle state initiates a service request and triggers the activation of the carrier frequency of the cell during the connection establishment phase. or

Implementation 2): The user in the idle state receives the paging message sent by the network side, and triggers the activation of the cell/base station when sending a paging response.

Method 2: Toggle command activation. When the cell where the carrier frequency is located receives the switching request command, it executes the activation of the carrier frequency of the cell. Specific applications may include switching activation of the X2 interface and switching activation of the S1 interface.

FIG. 5 shows a schematic diagram of switching activation using the X2 interface. The X2 interface is the interface between the base station and the base station in the E-UTRAN (Evolved Universal Mobile Telecommunications System Territorial Radio Access Network, Evolved Universal Mobile Telecommunications System Territorial Radio Access Network) network structure. As shown in the figure, it includes the following steps:

Step S501: the base station 501 receives a carrier frequency activation command.

Step S502: If the transmission link of the X2 interface has been released, re-establish the transmission link of the X2 interface to the adjacent base station 502, that is, SCTP (Stream Control Transmission Protocol, Stream Control Transmission Protocol) coupling.

Step S503: the base station 501 sends an X2 establishment message to the adjacent base station 502, the message carries a cell carrier frequency activation notification indication, or notifies the adjacent base station of cell activation through a dedicated message.

Step S504: The adjacent base station 502 sends an activation notification response message to the base station 501.

FIG. 6 shows a schematic diagram of switching activation using the S1 interface. The S1 interface is the interface between the base station and the MME or SAE (System Architecture Evolution, System Architecture Evolution) gateway in the E-UTRAN network structure. As shown in the figure, it includes the following steps:

Step S601: the base station 601 receives a cell carrier frequency activation command.

Step S602: If the transmission link of the S1 interface has been released, re-establish the transmission link of the S1 interface to the MME 602, that is, the SCTP coupling.

Step S603: The base station 601 sends an S1 establishment message to the MME 602, and the message carries a cell carrier frequency activation notification indication. Or notify the adjacent base station of cell activation through a dedicated message.

Step S604: MME 602 sends an activation notification response to base station 601.

Method 3: Activate on the network side. Other nodes in the network such as adjacent base stations, MME, and OAM trigger activation through explicit signaling.

Method 4: Event trigger activation. When the traffic or load within the coverage area of the cell where the carrier frequency is located reaches a certain level (or threshold), for example, greater than a predetermined fourth threshold value, the system triggers the activation procedure of the carrier frequency of the cell.

Method 5: Timing activation. When the preset activation time arrives, the carrier frequency will be activated.

After the carrier frequency in the cell is activated, the cell can also notify adjacent nodes or OAM.

In the above description of the technical solution, the object of directly implementing the switching of the working mode is the carrier frequency in the cell. Those skilled in the art should be able to understand that in practical applications, the carrier frequency in the entire cell can also be switched as a whole. Action, at this time, several working modes can be defined for the cell, for example, it can include:

Working mode 0: normal working state. A cell in this state does not perform energy saving.

Working mode 1: Specific services are restricted or specific users are restricted. In order to save resource consumption, a cell in this state can only provide specific services, or only provide services to specific users. Restriction of specific services may be to restrict certain types of specific service access, such as restricting VOIP service, high-speed data service access, etc.; it may also be to provide only specific services, such as only providing VOIP service, etc. Restricting specific users may be restricting access of specific users, such as restricting access of low-priority users; it may also be providing services only to specific users, such as providing services only to gold medal users.

Working mode 2: For a cell in this state, the sending period of the downlink synchronization channel and the broadcast channel is extended. During the intermittent period of each transmission cycle, the downlink common channel will be stopped to achieve the purpose of energy saving.

Working mode 3: the downlink channel is limited. In this state, in order to save energy consumption, the downlink channel is turned off, the uplink of the cell is still in the receiving state, all dedicated channels are turned off in the downlink of the cell, and the downlink of the cell only keeps sending SCH (Synchronization Channel, synchronization channel) and BCH (Broadcast Channel, broadcast channel), that is to say, the cell still sends the synchronization channel and the main system information block of the system in the downlink.

Working mode 4: Specific channels are limited. The carrier frequency in this working mode can only close the downlink data channel to reserve the common control channel, or close the uplink and downlink data channels to keep the downlink control channel and uplink random access channel. In this mode, each channel is considered separately.

Working mode 5: The cell/base station in this state, in addition to having the attributes of working mode 3, the X2/S1 interface link of the cell is also in the closed state.

Working mode 6: The cell is closed. Cells in this state will be completely shut down without any energy loss.

Working mode 7: The carrier frequency is off. A multi-carrier system in this state, such as the LTE Advance (LTE-A) system, turns off one or several subcarrier frequencies and operates on the main carrier frequency and other subcarrier frequencies; or turns off all subcarrier frequencies and operates on on the main carrier frequency. A multi-carrier cell in this state, such as a TD-SCDMA system cell, will turn off one or several carrier frequencies and operate on the main carrier frequency and other sub-carrier frequencies; or turn off all sub-carrier frequencies and run on the main carrier frequency. on the carrier frequency.

From the definition of the working mode above, it can be seen that the working mode definition of the cell is related to the working mode definition of the carrier frequency in the cell. For example, when all the carrier frequencies in the cell are in the completely closed working mode, the current working mode of the The mode should correspond to cell off.

Those skilled in the art should be able to understand that switching the working mode of the cell can be accomplished by switching the working mode of the corresponding carrier frequency therein.

Similarly, for a base station corresponding to multiple cells, several working modes may also be predefined, and these working modes are in turn related to the working modes of the corresponding cells. Therefore, switching the working mode of the base station can also be accomplished by switching the working mode of the carrier frequency.

The concept of Tracking Area (TA, Tracking Area) is introduced in the E-UTRAN network. In a wireless communication network, a tracking area (TA, Tracking Area) is uniquely identified by a tracking area code (Tracking Area Code, TAC). A Tracking Area (TA, Tracking Area) may include one or more cells. Different cells in a base station may belong to different tracking areas (TA, Tracking Area). However, for the convenience of management, in practical applications, one or more base stations are generally divided into a tracking area (TA, Tracking Area). In this way, several working modes can also be defined for the tracking area, and these working modes are related to the working mode of the base station, so the switching of the working mode of the tracking area can also be completed by switching the working mode of the carrier frequency.

In addition, in order to achieve a higher peak rate and improve spectrum utilization, the concept of carrier aggregation (Carrier Aggregation) is proposed in the LTE-A mobile communication system. The basic principle of carrier aggregation (CarrierAggregation) is to aggregate multiple carriers in an LTE-A mobile communication system to achieve a transmission bandwidth greater than 20 MHZ. Carrier Aggregation (Carrier Aggregation) is divided into two cases. One is that multiple LTE carriers are aggregated into a single LTE-A carrier, which is called inter-carrier aggregation. For example, five 20MHZ LTE carriers are aggregated into one LTE-A carrier with a bandwidth of 100MHZ. The other is the aggregation between multiple spectrum slices (Spectrum Aggregation), which is called Spectrum Aggregation. It can be seen that the carrier aggregation can also be used to define the working mode, and the switching process of the carrier aggregation working mode can also be completed by switching the working mode of the carrier.

Specifically, when all carrier frequencies in the cell meet the conditions for transitioning to the energy-saving mode, the cell is triggered to switch to the target energy-saving mode of the cell.

When all the cells in the base station meet the conditions for transitioning to the energy saving mode, the base station is triggered to transition to the target energy saving mode of the base station.

When all base stations in the tracking area meet the conditions for transitioning to the energy-saving mode, the tracking area is triggered to transition to the target energy-saving mode.

To sum up, in the embodiment of the present invention, the carrier frequency is migrated to the target energy-saving mode according to the working state of the carrier frequency, so that the carrier frequency in the cell can be energy-saving according to the actual working situation, thereby reducing the energy consumption of the cell , reduce the operator's operating costs, and promote environmental protection.
