Description

System and method for resource control of users

Technical field

The present invention relates to the field of mobile communications, and in particular, to a system and method for resource control of a user.

Background technique

The home base station is a small, low-power base station deployed in indoor places such as homes and offices. The main purpose is to provide users with higher service rates and lower the cost of using high-speed services, while making up for existing distributed Insufficient coverage of cellular wireless communication systems. The advantages of home base stations are affordability, convenience, low power output, plug and play, and more.

The home base station can access the core network through the logical network element of the home base station gateway, as shown in FIG. 1 , wherein the main functions of the home base station gateway are: verifying the security of the home base station, processing the registration of the home base station, and operating the home base station. Maintenance management, configuration and control of the home base station according to the operator's requirements, responsible for exchanging data of the core network and the home base station. In Figure 1, the home base station gateway can be set up with the access gateway or separately. There can also be no home base station gateway. At this time, the home base station directly connects with the access gateway. Among them, anchor SFA (Anchor Service Flow Authorization), anchor PCEF (anchor policy and charging execution function, Anchor PCEF), service SFA are AGW (Access Gateway, Access Service Network Gateway) Functional entity. SFM (Service Flow Management) is a functional entity of a home base station. Both the home base station and the access gateway belong to the network entity in the ASN (Access Service Network). The Policy and Charging Rules Function (PCRF) is a policy and charging rule function entity that is responsible for initiating the establishment of service flows, guaranteeing the quality of service (QoS) of service data, and performing charging control. .

In the home base station system, there is a concept of Closed Subscriber Group (CSG), which allows a user to access one or more CSG cells with limited access. The usage modes of the home base station can be classified into a closed mode, a mixed mode, and an open mode. When the home base station is in the closed mode, only the CSG user to which the home base station belongs can access the base station and enjoy the service provided by the base station. When home When the base station is in the open mode, any user can access the base station, and the home base station at this time is equivalent to the macro base station. When the home base station is in the hybrid mode, it allows the CSG user to access and allows other users to access the user. However, different user types are distinguished according to whether the user belongs to the CSG list, and differentiated service quality processing is implemented, that is, Users of CSG have higher service priorities when using hybrid home base stations, with better quality of service and service categories. At the same time, there are also high-priority and low-priority points for users of the same category (such as non-CSG users), and differentiated treatment is also required when performing service flow resource allocation.

When a high-priority user (such as a CSG user) accesses a closed or mixed mode home base station, if the radio resources are insufficient, the home base station will not allow the user to access the system or release some low-priority users (such as low). Priority non-CSG users) This will cause low-priority users to fail to run the established services, thus reducing the user experience.

The user completes the user plane capability negotiation with the base station and the access gateway.

Step 202: The anchor SFA initiates a service flow creation request to the service SFA, and carries indication information indicating whether to modify the service flow.

The indication information may be an indication that the modification of the service flow is allowed to be explicitly indicated, such as a Reduced Resource Code or a QoS type of the service flow ^ 爹 '爹 is changed to BE (Best Effort, best effort) The indication may also be a parameter. When the parameter is a specified value, it indicates that the service flow is allowed to be modified. When the parameter is other values, it indicates that the service flow is not allowed to be modified.

Step 203: The service SFA checks to create a data tunnel, and then initiates a tunnel registration request to the SFM, and carries the QoS parameter of the service flow, and whether the information indicating that the service flow is allowed to be modified is allowed.

Step 204: The home base station saves the Reduced Resource Code or / and the indication that is allowed to be modified to BE, and checks the radio resource to perform admission control.

When the parameter is a specified value, it indicates that the service flow is allowed to be modified. When the parameter is other values, the modification of the service flow is not allowed.

Step 302: The home base station sends a reception confirmation message.

Step 303: The home base station may save indication information about whether to modify the service flow, and check the radio resource to perform admission control.

Step 304: The home base station sends a tunnel registration request to the service SFA, and carries indication information indicating whether to allow the service flow to be tamper-modified.

Step 305: The service SFA sends a resource reservation request to the anchor SFA, and carries indication information indicating whether to allow the service flow to be tamper-modified.

The high-priority user completes the negotiation of the user plane capability with the base station and the access gateway.

Step 403: The anchor SFA initiates a service flow creation request to the service SFA.

Step 404: The service SFA checks to create a data tunnel, and then initiates a tunnel registration request to the SFM, and carries the QoS parameter.

Step 405: The SFM checks the radio resource, and determines whether to accept the tunnel registration request according to the QoS parameter and the available resource condition. If the resource is insufficient and the user is a high-priority user, the resource required by the high-priority user, the resource occupied by the current low-priority user, whether there is any indication of whether to allow modification of the service flow, the service flow priority, and the user Priority to determine which non-BE traffic flows of which low priority users are modified.

If the SFM finds that there is a non-BE traffic flow for the low priority user, and saves the permission to If the low priority user does not modify the indication information of the non-BE service flow, the SFM selects the non-BE service flow for modifying the service flow, and then performs steps 406 and 410;

Step 412: The anchor SFA or the anchor PCEF determines, according to the PCC policy, the local policy, or the subscription information, that if the resource reservation request is accepted, the service SFA resource reservation response message may be sent, and the QoS parameter may be carried.

Step 413: The anchor SFA sends a resource reservation response to the service SFA.

Step 414, the service SFA sends a tunnel modification response to the SFM.

Step 415: The SFM performs a resource allocation operation, that is, re-allocating the service flow of the low-priority user. Step 416: The SFM sends a dynamic service request message to the terminal of the low priority user.

Step 417: The terminal of the low priority user sends back a dynamic service response message to the SFM.

Step 505: The SFM checks the radio resource, and determines whether to accept the tunnel registration request according to the QoS parameter of the high priority user service flow and the available resource condition. If the resource is insufficient and the user is a high-priority user, determine which non-priority users are selected according to the resources required by the high-priority user, the current low-priority user resource, the service flow priority, and the user priority. The BE service flow is modified.

If it needs to accept, it responds to the service SFA resource reservation response message and can carry QoS information.

Step 513: The anchor SFA sends a resource reservation response to the service SFA. In step 514, the serving SFA sends a tunnel modification response to the SFM.

Step 515: The SFM performs a resource allocation operation, that is, reallocating resources for the service flow of the low priority user.

Step 516: The SFM sends a dynamic service request message to the low priority user terminal.

Step 517: The terminal sends back a dynamic service response message to the SFM.

Step 518, the SFM performs a dynamic service confirmation operation.

In step 519, the SFM confirms the tunnel modification to the serving SFA.

If the home base station does not have sufficient resources for the high priority user, the resource control processing flow for the low priority user is very similar to the above embodiment. Therefore, the description will not be repeated here.

During the process of establishing or modifying a high-priority user service flow, the SFM may also select an object for modifying the service flow in the manner as described in FIG. 5, and how to complete the modification of the service flow, that is, the SFM does not perform according to whether the save is available. The service flow modification instruction is used to select the service flow of the low priority user, but the reason for the service flow modification is carried when the tunnel modification request of the low priority user is sent to the service SFA, and the specific operation is similar to the embodiment described in FIG. 5, The description will not be repeated here.

FIG. 7 is a flow chart of resource control performed by the high priority user access process provided by the present invention on the basis of the home base station system of FIG. 1. For this embodiment, one or more low priority user service flows already exist in the home base station system before the high priority user accesses. The home base station can determine whether to allow the service flow modification to be performed according to whether or not the modification of the service flow is allowed. The home base station notifies the network side that the service flow needs to be modified, but the notification message does not carry the QoS parameter, and the network side initiates the service flow modification operation. The specific steps are described as follows:

Step 701: The low priority user has accessed the home base station system, and the corresponding service flow is established. Step 702: The high-priority user accesses the system, completes the authentication capability negotiation with the base station and the access gateway, and performs an authentication and authorization operation. The high-priority user completes the user plane capability negotiation with the base station and the access gateway.

Step 703: The anchor SFA initiates a service flow creation request to the service SFA.

Step 704: The service SFA checks to create a data tunnel, and then initiates a tunnel registration request to the SFM, and carries the QoS parameter.

Step 705: The SFM checks the radio resource, and determines whether to accept the tunnel registration request according to the QoS parameter and the available resource condition. If the resource is insufficient and the user is a high-priority user, the resource required by the high-priority user, the current low-priority user occupies resources, whether to allow modification of the service flow, the service flow priority, and the user priority. To determine which non-BE traffic flows of which low priority users are downgraded.

If the SFM finds that there is a non-BE service flow of the low priority user, and saves the indication information that allows modification of the low priority user non-BE service flow, the SFM selects the non-BE service flow for the service flow modification, and then executes Steps 706 and 710;

Step 706: Perform dynamic service establishment between the home base station and the terminal.

Step 707: The SFM returns a tunnel registration response to the service SFA.

Step 708: The service SFA returns a resource reservation response to the anchor SFA.

Step 710, the step is performed after step 705, and may be processed in parallel with step 706. The SFM sends a tunnel modification notification to the service SFA, which carries the user information (such as the user identifier) and the user service flow information (such as the service flow identifier), the manner of modifying the service flow, or/and the reason for modifying the service flow; In this embodiment, when the SFM sends a tunnel modification notification to the serving SFA, the modified QoS parameter is not carried, and the modified QoS parameter is determined by the network side.

Step 711: The service SFA sends a resource reservation notification of the low priority user to the anchor SFA. With the user ID, the service flow identifier, the way the service flow is modified, or/and the reason for the service flow modification. Step 712: If there is a PCC, the SFA forwards the notification message to the anchor PCEF, and the session between the PCEF and the PCRF is updated. If the resource reservation notification carries the reason for modifying the service flow, the PCRF performs the service flow according to the The reason for the modification and whether the indication information for allowing the service flow modification is saved is judged whether or not to accept the modification according to the manner indicated by the notification. If accepted, the PCC rule of the BE type is sent to the anchor PCEF; if the resource reservation notification is not carried The reason for the modification of the service flow is that the PCRF determines whether to accept the modification according to the indication indicating whether the service flow modification is permitted or not, and if yes, sends a PCC rule of the BE type to the anchor PCEF.

Step 713: The anchor SFA or the anchor PCEF initiates a service flow modification process according to the PCC rule, the local policy or the subscription information, and the modification reason in the manner indicated by the resource reservation notification.

In order to simplify the description, the foregoing embodiment uses an application scenario when a high-priority user accesses as an example to describe a manner in which a home base station performs resource control, and other implementation scenarios, such as triggering an access gateway to establish or modify a service flow, The PCC triggers the access gateway to establish or modify the service flow, and the terminal initiates the service flow establishment or modification. If the home base station does not have enough resources to provide the high priority user, the information may be directly determined according to whether the service flow modification instruction is allowed. In the scenario of modifying the service flow, the SFM sends a tunnel modification notification to the service SFA, which carries the user information (such as the user ID) and the user service flow information (such as the service flow identifier), the manner of modifying the service flow, or / and the reason for the modification of the service flow; the PCRF determines whether it can be modified in the manner indicated by the notification. In addition to the reason for the modification, it should also check whether there is an indication that the service flow modification is saved, that is, whether the service flow modification is allowed. Instructions, if yes, accept The modified notification in the manner indicated, without indicating the notice is not accepted according to proceed in the manner indicated modifications.

FIG. 8 is a flow chart of resource control in a high priority user access process provided by the home base station system of FIG. 1 according to the present invention. For this embodiment, one or more low priority user service flows already exist in the home base station system before the high priority user accesses. The home base station can determine whether to allow the service flow to be modified to the BE type according to whether the information indicating that the service flow is allowed to be modified is allowed. In the case of insufficient resources, the home base station first performs a handover operation on the low priority user, and if the handover fails, initiates a process of modifying the low priority user service flow.

Step 803: The anchor SFA initiates a service flow creation request to the service SFA.

Step 804: The service SFA checks to create a data tunnel, and then initiates a tunnel registration request to the SFM, and carries the QoS parameter.

Step 805: The SFM checks the radio resource, and determines whether to accept the tunnel registration request according to the QoS parameter and the available resource condition. If the resource is insufficient and the user is a high-priority user, the low-priority user needs resources, the current low-priority user resource, and the user priority to determine which low-priority users to switch. The user with the lowest level makes a selection, or it can be a random selection.

If it is necessary to switch the low priority users (User 1 and User 2), step 807 is executed to initiate the handover request.

Step 806, continuing to execute the high priority user service flow establishing process.

Step 807, the step is performed after step 805, and may be processed in parallel with step 806. The home base station sends a handover request to the target ASN1, carrying information of User 1 and User 2, such as the identifiers of User 1 and User 2.

Step 808: The home base station simultaneously sends a handover request to the target ASN2, carrying information of the user 1 and the user 2, such as the identifiers of the user 1 and the user 2.

Step 809, the target ASN1 responds to the home base station with a handover response.

Step 810: The target ASN2 responds to the home base station with a handover response.

Step 811: If the handover user 1 fails (for example, the handover response indication of the target ASN1 response fails), the serving home base station may modify the service flow according to the required resources of the high priority user, the current low priority user occupation resource, and the service flow. The indication information, the traffic priority, is used to determine which non-BE traffic flows of the user 1 are modified to the BE type. The home base station performs modification processing on the non-BE service flow that the user 1 allows to modify, and releases the non-BE service flow that is not allowed to be modified. Here, the home base station is served, that is, the home base station where the user switches before;

If the SFM finds that there is a non-BE service flow of the low priority user, and saves the indication information that allows the modification of the service flow, the SFM will modify the non-BE service flow that the user 1 allows to modify, and issue a low priority to the service SFA. The tunnel modification request of the level user, requesting to modify the QoS type of the service flow to the BE type, and carrying the modified QoS parameter.

Step 812: The serving SFA sends a resource reservation request of the low priority user to the anchor SFA, requesting to modify the QoS type of the service flow to the BE type, and carrying the modified QoS parameter.

Step 813: The anchor SFA or the anchor PCEF determines, according to the PCC policy, the local policy, or the subscription information, that if the resource reservation request is accepted, the service SFA resource reservation response message may be carried, and the QoS information may be carried.

Step 814: The anchor SFA sends a resource reservation response to the serving SFA.

Step 815: The service SFA sends a tunnel modification response to the SFM.

Step 816, the SFM performs a resource allocation operation.

Step 817: The SFM sends a dynamic service request message to the terminal.

Step 818: The terminal sends back a dynamic service response message to the SFM.

Step 819, the SFM performs a dynamic service confirmation operation.

Step 820, the SFM confirms the tunnel modification to the service SFA.

Step 821, the service SFA confirms the resource reservation to the anchor SFA.
