technical field

The present invention relates to the communication field, in particular to a user service resource management method and device.

Background technique

The EPS (Evolved packet system) system of 3GPP (3rd Generation Partnership Project) is divided into E-UTRAN (Evolved Universal Terrestrial Radio Access Network) and Evolved Packet The EPC (Evolved packet core) of the core network consists of two parts. The mobility management unit MME (mobility management entity) in the EPC is responsible for NAS (NonAccess Stratum) signaling management from the terminal to the network, bearer management, and user idle mode Tracking and paging management functions, etc. The main network element in E-UTRAN is eNodeB (E-UTRAN NodeB, base station). The eNodeB is responsible for sending and receiving wireless signals, and communicates with terminals through the air interface.

Taking a home base station as an example, a home base station Home eNodeB (HeNB) is a type of base station eNodeB, which is deployed as a dedicated resource in places such as homes, groups, companies, or schools. ) to control the access of users such as family members and group members. CSG cells are divided into closed-mode CSG cells and mixed-mode CSG cells. For a CSG cell in closed access mode, if a user subscribes to the CSG or is added to the CSG by the CSG administrator, the user is allowed to normally reside in the CSG cell and apply for services; for users who do not belong to the CSG , services cannot be initiated in the CSG cell. For a CSG cell in hybrid access mode, both users belonging to the CSG and users not belonging to the CSG are allowed to access. In the hybrid CSG cell, the HeNB gives priority to guaranteeing the right of users belonging to the CSG to use resources. Multiple CSG cells can share the same CSG ID.

In the process of realizing the present invention, the inventor found that the following problems existed in the prior art:

The Home eNodeB can be connected to the MME through the S1 interface, as shown in Figure 1A, and can also be connected to the MME through the HeNB GW entity, as shown in Figure 1B. Therefore, the access control of the prior art is performed at the MME, and the MME can differentiate the access Whether a user of a CSG cell belongs to the CSG, and access control is performed according to whether the CSG cell is in closed access mode or hybrid access mode. The HeNB itself cannot distinguish whether the user who accesses through the CSG cell supported by the HeNB belongs to the CSG. Therefore, for a CSG cell in a hybrid access mode, because users who do not belong to the CSG are allowed to access, users who do not belong to the CSG may preempt the resources of users belonging to the CSG, and the resources of users belonging to the CSG cannot be guaranteed. Right of Priority. In addition, for a closed access mode CSG cell, for a connected user, after the subscription information is changed to no longer belong to the current CSG, continuing to allow the user to perform services in the current CSG cell will affect the resource usage of other CSG users.

Contents of the invention

In order to solve the problem that the hybrid access mode CSG cell first guarantees CSG user resources, and the closed access mode CSG cell, for a connected user, after the subscription data is changed to no longer belong to the current CSG, it will affect the use of resources by other CSG users.

In this embodiment, the correspondence between the UE and the CSG may be information indicating whether the UE is a user belonging to the CSG to the base station eNB/HeNB. In this case, the MME judges whether the UE is a user of the CSG according to the received CSG ID. It is a user belonging to the CSG, and indicates to the eNB/HeNB whether the UE is a user belonging to the CSG in the initial context establishment message. For example, the indication information may be a 1-bit identifier added to the initial context establishment message, but it is not limited to this form. If the base station supports multiple CSGs, the initial context establishment message may also include the CSG ID or cell identity of the CSG corresponding to the indication information.

In this embodiment, the correspondence between the UE and the CSG may also be a CSG list that the user is allowed to access. In this case, after receiving the initial UE message, the MME sends the CSG list that the user is allowed to access to the base station , the base station can judge whether the user is a user of the CSG by comparing the list with the CSG it supports.

More preferably, in this embodiment, the correspondence between the UE and the CSG may also be a list of CSGs supported by the base station that the user is allowed to access. In this case, the MME only sends the The inbound CSG list is given to the base station, and the base station can judge whether the user is a user of the CSG by comparing the list with the CSG supported by itself.

402: The target base station responds to the handover request message.

According to this embodiment, the corresponding relationship between the user terminal and the closed user group may also be transmitted through the UE context modification request message, and this embodiment will be described below with reference to the accompanying drawings.

Figure 5 shows that when the subscription information of the UE changes in the connected state, in the mixed-mode CSG cell currently being accessed, the user who does not belong to the CSG changes to the user who belongs to the CSG, or the user who belongs to the CSG changes to a user who does not belong to the CSG. In the case of a user belonging to the CSG, or when the MME finds that the UE has changed a cell or CSG on the same base station, the MME updates the base station with the indication of whether the UE belongs to the CSG. The process includes:

501: The MME sends a UE context modification request message to the base station, which may be a home base station or a macro base station supporting a CSG cell, according to the change of the subscription information or the movement of the UE, and carries the UE and the CSG in the UE context modification request message. corresponding relationship.

In this embodiment, the correspondence between the UE and the CSG may indicate whether the UE is a user belonging to the CSG. For example, this indication may be a 1-bit identifier added to the UE context modification request message, but it is not limited to this form. If the base station supports multiple CSGs, the UE context modification request message may also include the CSG ID or cell identity of the CSG corresponding to the indication.

502: The base station responds with a context modification response message.

The process shown in Figure 5 can also be used when the network switches a UE in a connected state to a CSG cell in hybrid access mode. The embodiment shown in Figure 4 does not send an indication when establishing an S1 connection. After the S1 of the base station is connected, the method of updating the UE context is used to send the indication.

Step 202 according to this embodiment:

According to the previous step 201, the base station obtains an indication of whether the UE belongs to the current CSG user, or obtains the CSG list that the UE is allowed to access, or obtains the CSG list supported by the base station that allows the user to access, and can distinguish the CSG supported by the base station. Users belonging to the CSG and users not belonging to the CSG in the mixed access mode CSG cell can allocate service resources according to actual conditions.

According to this embodiment, when the resources in the CSG cell are insufficient to meet the needs of the users belonging to the CSG, for example, the bearer of the users belonging to the CSG cannot be established due to insufficient resources or the remaining resources are less than the threshold configured on the base station, the base station can Directly release the S1 logical link of the user not belonging to the CSG and reclaim the resources occupied by the user, so as to ensure the priority use of resources by the user belonging to the CSG; the base station may not directly release the S1 logical link of the user not belonging to the CSG, but Handover users who do not belong to the CSG to other cells.

In this embodiment, handing over users not belonging to the CSG to other cells can be implemented by the method shown in FIG. 6. Please refer to FIG. 6. The method includes:

601: Determine the target cell according to the configuration of the source base station or the measurement of surrounding base stations;

In this embodiment, if the CSG list that the user is allowed to access is received, the target cell may be further determined according to the CSG list that the user is allowed to access.

602: Perform link switching to the target cell.

In this handover method, the selection of the target base station and cell is based on blind switching, that is, the target base station and cell are selected according to the configuration of the source base station or the measurement of surrounding base stations, and then the link is switched. Among them, if the base station receives the CSG list that allows the user to access, the CSG list obtained by the base station that allows the UE to access can also be used to compare with the optional target base station and the CSG ID of the cell to select a target base station that is more suitable for the UE and neighborhood.

In this embodiment, switching users not belonging to the CSG to other cells can also be implemented by the method shown in FIG. 7, please refer to FIG. 7, the method includes:

701: Select a target cell according to the measurement report of the user terminal;

702: Perform link switching to the target cell.

In this handover method, the target base station and the cell are selected according to the measurement report of the UE. Wherein, the CSG list obtained by the base station that allows the UE to access can also be used for comparison with the CSG IDs of the optional target base stations and cells, so as to select target base stations and cells that are more suitable for the UE.

In the handover method of this embodiment, the target base station and the cell are selected according to the UE's measurement report, and the base station should actively request the UE to report the measurement report. In this case, please refer to FIG. 8. The interaction process between the base station and the UE includes:

801: The base station judges that a user handover needs to be initiated according to its own resource conditions, and then sends a report request message to the UE, requesting the UE to report a current measurement report.

802: The UE reports its own measurement report after receiving the report request message, and the base station selects a target handover cell for the UE according to the measurement report.

After the base station selects the target handover cell, it can initiate the handover of the UE.

In this embodiment, according to preset settings, if the handover fails, the base station can keep the resource of the UE or directly release the S1 logical link of the user.

Among them, the process of directly releasing the logical link of user S1 triggered by handover failure is shown in Figure 9, and the process includes:

901: The base station selects the target base station and cell and sends a handover request message to the MME, requesting to handover a UE to the target base station and cell;

902: the MME returns a rejection message;

903: After receiving the handover rejection message, the base station sends a UE context release request message to the MME to recover UE resources.

The methods in the embodiments of the present invention are described by taking the direct connection architecture between the base station and the MME in FIG. 1A as an example. Corresponding to the architecture in which the base station is connected to the MME through the gateway GW in FIG. To complete the information exchange, the specific process is similar to the method in this embodiment, except that intermediate nodes are added, which will not be described in detail.

According to the architecture in which the base station completes information interaction with the MME through the gateway in this embodiment, the gateway receives the correspondence between the user terminal and the closed user group sent by the MME, and forwards it to the base station. In this embodiment, the correspondence between the UE and the CSG sent by the MME received by the gateway may be: indication information indicating whether the user terminal belongs to the closed user group; or a list of closed user groups that the user terminal is allowed to access ; or a closed user group list supported by the base station that allows the user to access, which is not limited in this embodiment.

In this embodiment, when the corresponding relationship is a closed user group list that the user terminal is allowed to access, the gateway can filter the closed user group list, and only the closed user group supported by the base station that allows the user to access The group list is sent to the base station so that the base station allocates service resources according to the list.

In this embodiment, when an idle state UE accesses the network from a CSG cell in a hybrid access mode, or when the network decides to switch a connected state UE to a CSG cell in a hybrid access mode, whether the MME belongs to the hybrid access mode The instruction of the CSG in the access mode is sent to the base station, where the base station can be a home base station or a macro base station supporting CSG cells, and the base station can distinguish whether the users in the CSG cells it supports belong to the CSG users or not according to the received instructions. The users belonging to the CSG are given priority to ensure the right to occupy resources of the CSG users in the event of resource competition.

In this embodiment, when the MME establishes an S1 connection for a UE, it sends the CSG list that the user is allowed to access to the base station. More preferably, the MME only sends the CSG list that the base station supports to allow the user to access the base station. According to the received CSG list, the base station can distinguish whether the users allowed to access the supported CSG cells are users belonging to the CSG or users not belonging to the CSG. Or, the base station itself can configure the user ID list corresponding to the CSG cells it supports, and the base station can distinguish whether the users in the CSG cells it supports belong to the CSG users or not belong to the CSG users according to the user IDs received from the UE. , so that in the case of resource competition, the right to preferentially occupy resources belonging to the CSG user is guaranteed first.

In the case of resource competition between users not belonging to the CSG and users belonging to the CSG, resources are preferentially allocated to users belonging to the CSG to ensure that users belonging to the CSG have the right to occupy resources first.

Embodiment three

The embodiment of the present invention also provides a method for managing user service resources, and the method of this embodiment will be described below with reference to the accompanying drawings.

FIG. 11 is a flow chart of the method in this embodiment. Please refer to FIG. 11. The user service resource management method in this embodiment mainly includes:

1101: The mobility management device instructs the base station to reclaim service resources according to the closed user group resource shortage information sent by the base station or according to the change of user subscription information.

In this embodiment, the resource shortage information is transmitted through a resource indication message, or through a bearer establishment failure message.

In this embodiment, when the mobility management device learns that the resources of the base station are insufficient according to the resource shortage information, or when the mobility management device finds that the subscription information of the user has changed, it can instruct the base station to reclaim the service of the specific user when necessary. resources, such as releasing the S1 connection of at least one user not belonging to the closed user group; or handing over at least one user not belonging to the closed user group to the target cell.

FIG. 12 is a flow chart of the base station sending a resource shortage indication message to the MME when resources are insufficient in this embodiment. Please refer to FIG. 12 , the process includes:

1201: A base station, which may be a home base station or a macro base station supporting a CSG cell, sends a resource indication message to the MME when the resources of the CSG cell in the hybrid access mode supported by it are insufficient. If the base station supports multiple cells, the message may carry an identifier of a cell with insufficient resources.

After receiving the resource indication message, the MME knows that the resources of the base station are insufficient, and selects a user that does not belong to the user group of the CSG cell to instruct the base station to release its S1 connection directly, so that the base station can reclaim the resources occupied by the user. The MME may also not instruct the base station to directly release the user's S1 logical link, but instruct the base station to handover the user to another cell or base station.

Figure 13 is a flow chart of the MME switching the user to another cell or base station, please refer to Figure 13, the process includes:

1301: When the MME needs to take the initiative to switch a user to another cell or base station, it sends a trigger message to the source base station. The trigger message contains indication information, which is used to indicate that the base station has insufficient resources and needs to switch the user, or indicates that the subscription information of the user has changed, for example The user no longer belongs to the CSG, or for a CSG cell in closed access mode, the indication information may also indicate to the user that the user no longer belongs to the CSG, and access from the cell is no longer allowed. In order to assist the base station in selecting a target base station and a cell, the message may also carry a list of CSGs that the user is allowed to access.

1302: After receiving the trigger message, the base station selects a target base station and a cell. The selection here may be based on blind switching or requires the UE to report a measurement report. The specific method for selecting the target base station and cell is the same as that in Embodiment 1, and will not be repeated here. After the base station selects the target base station and the cell, it sends a handover request message to the MME.

1303: The MME sends a handover command to the source base station after notifying the target base station and the cell to prepare resources, and notifies the source base station to perform data handover. If the target base station cannot successfully prepare resources for the UE, the MME may directly initiate the release of the S1 logical link of the UE.

The methods in the embodiments of the present invention are described by taking the direct connection architecture between the base station and the MME in FIG. 1A as an example. Corresponding to the architecture in which the base station is connected to the MME through the gateway GW in FIG. To complete the information exchange, the specific process is similar to the method in this embodiment, except that intermediate nodes are added, which will not be described in detail.

Different from the foregoing embodiments, in this embodiment, the base station does not distinguish between users belonging to the CSG and users not belonging to the CSG in the CSG cell of the hybrid access mode supported by the base station. When the resources in the CSG cell are insufficient, for example, when the remaining resources are less than the threshold configured on the base station, the base station actively sends an indication to the MME, and the MME learns that the resources in the CSG cell are insufficient according to the indication; the base station may not send the resource indication, but use The messages in the prior art, such as the bearer establishment failure message, return the bearer establishment failure message to the MME when the bearer establishment fails and indicate that the reason is insufficient resources. According to the bearer establishment failure message, the MME judges that the user belonging to the CSG of the cell fails to establish due to insufficient resources. The MME selects users who do not belong to the user group of the CSG cell, and instructs the base station to release or transfer the resources occupied by them. The MME can also directly instruct the base station to reclaim service resources according to the change of user subscription information. Therefore, in the case of resource competition, the right to preferentially occupy resources belonging to the CSG user is guaranteed first.
