Description

The present invention relates to the field of communications, and in particular, to network load information, user location information, and a policy processing method and apparatus. BACKGROUND OF THE INVENTION The 3rd Generation Partnership Project (3GPP) evolved Evolved Packet System (EPS) is an evolved universal mobile communication system (Evolved Universal Terrestrial Radio Access Network). , referred to as E-UTRAN, Mobility Management Entity (MME), Serving Gateway (S-GW), Packet Data Network Gateway (P-GW) PDN GW;), Home Subscriber Server (HSS), 3GPP Authentication Authorization and Accounting (AAA) server, Policy and Charging Rules Function (referred to as Policy and Charging Rules Function) Composing for the PCRF) entity and other supporting nodes. 1 is a schematic diagram of a system architecture of an EPS according to the related art. As shown in FIG. 1, the mobility management entity is responsible for control planes such as mobility management, processing of non-access stratum signaling, and management of user mobility management context. The S-GW is an access gateway device connected to the E-UTRAN, which forwards data between the E-UTRAN and the P-GW, and is responsible for buffering paging waiting data; the P-GW is an EPS and packet data network ( Packet Data Network (referred to as PDN) The border gateway of the network, responsible for PDN access and forwarding data between EPS and PDN; S-GW and P-GW belong to the core network gateway; PCRF is the policy and charging rule function The entity is connected to the service network protocol (Internet Protocol, IP for short) service network to obtain service information. In addition, it is connected to the gateway device in the network through the Gx/Gxa/Gxc interface, and is responsible for initiating the IP bearer. Establishing, guaranteeing the quality of service (Quality of Service, QoS for short), and performing charging control. The EPS supports interworking with non-3GPP systems, wherein interworking with non-3GPP systems is implemented through an S2a/b/c interface, and the P-GW acts as an anchor between 3GPP and non-3GPP systems. In the system architecture diagram of EPS, non-3GPP systems are classified into trusted non-3GPP IP access and untrusted non-3GPP 接入> access. The trusted non-3GPP IP access can be directly connected to the P-GW through the S2a interface; the untrusted non-3GPP IP access needs to be connected to the P-GW through an Evolved Packet Data Gateway (ePDG), ePDG and P-GW The inter-interface is S2b. The S2c provides user plane-related control and mobility support between the user equipment (User Equipment, UE for short) and the P-GW. The supported mobility management protocol is dual-stack mobile IPv6. (Moblie IPv6 Support for Dual Stack Hosts and Routers, referred to as DSMIPv6). When performing a certain service, the operator may wish to obtain the load of the network, and decide how to perform the service according to the network load. For example, a push service in 3G technology, which is characterized by The operator needs to adopt the push mode (the so-called push mode means that the trigger of the service is from the service server of the operator, and the service execution can be negotiated with the user UE), for example: the operator sends an advertisement to the user. (video clips), notifications, etc.; such services are usually non-real-time services (so-called non-real-time services, which means that the service can be carried out at the current time or can be postponed). Operators can give network load when they want to launch Push-type services. For example, if the service is delivered to a user in a certain cell, if the current network load of the cell is heavy, you can temporarily disable the service and delay the execution of the service. If the current network load of the cell is light, the service is carried out. The advantages of this type of service are: It can effectively prevent the network load from being increased when the network load is heavy, and then perform such services when the network load is light. Thereby playing the role of the entire network load sharing. In the related art, it is not proposed to be able to provide network load information, and therefore it is not proposed how to provide network load information, so that some services cannot be better carried out.

At least one of: an attachment event, an access type change, a state separation event, a location update event, a handover event. The NMS receives the message, saves and maintains the user's information, and then provides the network load information to the PCRF for the PCRF to formulate the policy. The network load information may include: a cell busy list. The NMS can periodically provide network load information to the PCRF or provide network load information when replying to the PCRF request. For example, when the UE is attached to the network, the MME/SGSN (the SGSN in the 3G network, the MME in the EPS network) perceives the UE attachment, notifies the NMS user of the attachment event, and after the MS receives the message, saves the user. The information may be followed by network load information provided to the PCRF, and the PCRF formulates or updates and issues the policy based on the network load information. FIG. 9 is a flowchart of a method for acquiring network load information when a user attaches according to a preferred embodiment of the present invention. As shown in FIG. 9, the process includes the following steps: Step S902: A UE attaches to a network, and the attached process may be based on an existing Process, where IP-CAN refers to PCEF and/or BBERF. In the 3G network, the PCEF is deployed in the GGSN, and the BBERF is not deployed. In the EPS network, the PCEF is deployed in the P-GW, and the BBERF is deployed in the S-GW. In step S904, the MME/SGSN detects that the UE is attached to the network, and sends a user attach notification to the NMS. The carrying information may include at least one of the following: a user identifier (eg, IMSI International Mobile Subscriber Identification), a cell identifier (Cell lD), a routing area. RAI Routing Area Identifier; Preferably, a radio access type (RAT Radio Access Type) may also be included. Step S906, after receiving the message, the NMS saves and maintains the information of the user. Step S908, the MS returns a response to the MME/SGSN. Step S910, providing network management information (the network management information may be network load information, and may also include network load information). For example, at least one of the following methods may be adopted: (1) The PCRF may send a subscription to the NMS, for example: subscribe to a busy state change of one or several cells (for example, when the state of the cell changes from idle to busy, For example, a threshold may be defined. When the number of users in the cell exceeds the threshold, the status of the cell is considered to be busy. The event is reported, or the busy and idle state of the cell in which the user is located is reported. A response is returned to the PCRF. (2) The NMS can actively provide network load information to the PCRF, for example: timing (for example, every 5 minutes, for example, a fixed time every day), reporting the list information of the busy cells to the PCRF; or when the user attaches to the network. At this time, the state of the cell changes (for example, from idle to busy state), and the PCRF has previously subscribed to the event of the cell state change, and the MS is triggered by the event to provide the cell F with the change information of the cell state. The operator can also configure, without relying on the above subscription, when the cell status changes, the MS provides the cell status change information to the PCRF; the PCRF returns the response to the NMS after receiving the network load information. (3) The PCRF can actively query the NMS for network load information, for example: by carrying the cell identifier, querying the network load of one or several cells; or carrying the user identifier to query one or several users. The network load of the cell; or requesting the NMS to return the network load of all the cells; the MS returns a response to the PCRF, and the response message may include: a busy or idle state of the PCRF request or a certain cell, or The busy state of a cell in which one or several users are located; or the busy state of all cells. The PCRF formulates or updates the policy based on the busy state of the cell; the PCRF sends the policy to the PCEF/BBERF. When the UE changes handover, location update, or user status changes, the handover scenario is, for example, switching from one SGSN or S-GW to another SGSN or S-GW (the handover occurs between SGSNs in 3G, EPS network) The medium handover occurs between the SGWs, and the location update moves, for example, from one cell to another. The MME/SGSN (the SGSN in the 3G network and the MME in the EPS network) senses that the UE has a handover or a location update, and notifies the MS user of the handover event. After receiving the message, the MS saves the information of the user. The PCRF is based on the network load information. Or update and issue the policy. The preferred embodiment provides a method for acquiring network load information when a user changes handover, a location update, or a user status change, and FIG. 10 is a flowchart of a method for acquiring network load information when a user performs handover according to a preferred embodiment of the present invention. As shown in FIG. 10, the process includes the following steps: Step S1002: The UE performs handover, and the handover process may be based on an existing process, where IP-CAN refers to PCEF and/or BBERF. In the 3G network, the PCEF is deployed in the GGSN, and the BBERF is not deployed. In the EPS network, the PCEF is deployed in the P-GW, and the BBERF is deployed in the S-GW.

The MME/SGSN sends a user handover notification to the NMS, and the carried information may include: a user identifier (eg, IMSI International Mobile Subscriber Identification), a cell identifier (Cell ID), a routing area identifier (RAI Routing Area Identifier), and a radio access type (RAT). Radio Access Type), information related to wireless access, (eg: RNC Radio Network Controller ID in the 3G network, destination radio network controller ID). Step S1006: After receiving the message, the MS saves the user switching information. In step S1008, the MS returns a response message to the MME/SGSN. Step S1010: Provide network management information (the network management information may be network load information, and may also include network load information). For example, at least one of the following methods may be adopted: (1) The PCRF may send a subscription to the NMS, for example: subscribe to a busy state change of one or several cells (for example, when the state of the cell changes from idle to busy) Report the event, or subscribe to the busy and idle status change event of the cell where one or several users are located. Then the NMS returns a response to the PCRF. (2) The NMS can actively provide the network load information to the PCRF. For example, the timing (for example, every 5 minutes) reports the list information of the busy cells to the PCRF; or the cell where the UE is located when the user switches or the location is updated. The state changes (for example, from idle to busy), and the PCRF has previously subscribed to the event of the cell state change, and the NMS is triggered by the event to provide the cell F with the change information of the cell state. The operator can also configure, do not rely on the above subscription, when the cell status changes, the NMS will refer to the PCRF. Provide cell status change information. After receiving the network load information, the PCRF returns a response to the NMS. (3) The PCRF can actively query the NMS for network load information, for example: by carrying the cell identifier, querying the network load of one or several cells; or carrying the user identifier to query one or several users. The network load of the cell; or request the NMS to return the network load of all cells. The NMS returns a response to the PCRF. The response message may include: a busy or idle state of one or several cells requested by the PCRF, or a busy state of a cell in which the user is located; or busy of all the cells Idle state. The PCRF formulates or updates policies based on the busy state of the cell. The PCRF sends the policy to PCEF/BBERF. 11 is a flowchart of a method for acquiring network load information when a user is updated according to a preferred embodiment of the present invention. As shown in FIG. 11, the process includes the following steps: Step S1102: When a user location update occurs, the location update is performed. The process is based on an existing process, where IP-CAN refers to PCEF and P/ or BBERF. In the 3G network, the PCEF is deployed in the GGSN and the BBERF is not deployed. In the EPS network, the PCEF is deployed in the P-GW and the BBERF is deployed in the S-GW. In step S1104, the MME/SGSN sends a user location update notification to the NMS when the MME/SGSN detects the location update of the UE. The carrying information may include: a user identifier (eg, IMSI International Mobile Subscriber Identification), and a cell identifier (Cell ID). Step S1106: After receiving the message, the NMS saves the location update information of the user. Step S1108, the MS returns a response to the MME/SGSN.
