Description

The present invention relates to the field of communications, and in particular to a method, apparatus, and system for processing a user's local access service. BACKGROUND In order to maintain the competitiveness of the third generation mobile communication system in the communication field, the mobile communication service with faster rate, lower delay, and more personalized is provided for the user, and the operation cost of the operator can be reduced, and the third generation cooperation The Standards Working Group of the 3GPP (3rd Generation Partnership Project) is working on the Evolved Packet System (EPS). FIG. 1 is a schematic structural diagram of an evolved packet system in the prior art. As shown in FIG. 1, the entire EPS is divided into two parts: a radio access network and a core network. In the core network, the Home Subscriber Server (HSS) mobility management entity (MME, Mobility Management Entity), Serving GPRS Support Node (SGSN) policy charging rule function (PCRF, Policy and Charging Rule Function ), Service Gateway (S-GW, Serving Gateway) Packet Data Gateway (P-GW, PDN Gateway) and Packet Data Network (PDN, Packet Data Network) ₀ The following describes the functions of each part: Home subscriber server, located at The home network that the user subscribes to is used to permanently store the user subscription data. The mobility management entity is configured to store user subscription data of the current network, and is responsible for terminal-to-network non-access layer signaling management, terminal security verification function, terminal mobility management, user idle mode tracking, and paging. Management functions and bearer management. Serving GPRS support node, is a global mobile communication system (GSM, Global System for Mobile)

Communications ), EDGE, Enhanced Data Rate for GSM Evolution (GERAN, GSM EDGE Radio Access Network) and Universal Mobile Telecommunications System (UMTS), terrestrial wireless access The UMTS (UMTS Terrestrial Radio Access Network) and the service access point of the user accessing the core network are similar in function to the mobility management entity, and are responsible for location update, paging management, and bearer management of the user. The service gateway is the gateway of the core network to the wireless system, and is responsible for the user plane bearer of the terminal to the core network, the data buffer in the terminal idle mode, the function of initiating the service request by the network side, the lawful interception, and the packet data routing and forwarding. The function gateway is also responsible for counting the situation in which the user terminal uses the wireless network, and generates the CDRs of the terminal using the wireless network, and transmits the CDRs to the charging gateway. The packet data gateway is a gateway of the evolved system and the external packet data network of the system, and is connected to the Internet and the packet data network, and is responsible for the Internet Protocol (IP) address allocation, charging function, packet filtering, and policy of the terminal. Control, etc. The packet data network is the operator's IP service network, and the packet data network provides IP services to users through the operator's core network. The policy charging rule function entity is a server in the evolved system responsible for providing charging control, online credit control, threshold control, and QoS (Quality of Service) policy rules. The radio access network is composed of an evolved base station (e B, Evolved NodeB) and a 3G radio network controller (RNC,

Radio Network Controllor is mainly responsible for the transmission and reception of wireless signals, and communicates with the terminal through the air interface to manage the radio resources, resource scheduling, and access control of the air interface. The service GPRS support node is an upgraded SGSN, which can support the S4 interface with the service gateway, and communicates with the mobility management unit by using GPRS Tunneling Protocol version 2 (GTPv2). For the SGSN supporting the 3G core network, the packet switching (PS, Packet Switching) domain network architecture is different from that of Figure 1. In this case, the SGSN and the MME are connected by Gn interface, and the interworking uses the GPRS tunneling protocol version 1 (GTPvl, GPRS Tunneling). Protocol version 1); The SGSN cannot be connected to the serving gateway. It needs to connect to the Gateway GPRS Support Node (GGSN) through the Gn interface to directly access the packet data network. A home base station (HNB, Home NodeB) or an evolved home base station (He B, Home eNodeB) is a type of small, low-power base station that is deployed as a dedicated resource for certain users in private places such as homes, groups, companies, or schools. Use, mainly used to provide users with higher service rates and reduce the cost of using high-rate services, while making up for the lack of coverage of existing distributed cellular wireless communication systems. The advantages of home base stations are affordability, convenience, low power output, plug and play, broadband access, and the use of single mode terminals. 2 is a schematic diagram of a wireless network element accessing a core network in the prior art. The home base station can be directly connected to the core network. As shown in FIG. 2( a ), the home base station can also use the home base station gateway as the logical network element. Accessing the core network, as shown in Figure 2(b) and (c), the main function of the home base station gateway is to verify the security of the home base station, handle the registration of the home base station, and perform operation and maintenance management on the home base station, according to the requirements of the operator. Configure and control the home base station, which is responsible for exchanging data between the core network and the home base station. In order to implement local access functions (including Local IP Access (LIPA) or Selective IP Traffic Offload (SIPTO)), that is, terminals to other IP devices on the home network, IP devices in the enterprise network, or interconnections. Local access to the network, a local gateway is added, as shown in Figures 2(a) and 2(c); the addition of a local access gateway provides strong support for local access technologies, and the local gateway can be combined with the wireless side network element. It may be located in the vicinity of the wireless side network element (ie, external), or may be set up with the home base station gateway or near the home base station gateway (ie, external); wherein the local gateway includes the local S-GW (L-SGW, Local SGW) ), local PGW (L-PGW, Local PGW), local GGSN (L-GGSN, Local GGSN), and external local GW (L-GW, Local GW). In the mobile communication network architecture, for users who support local access, the data path of the local access and the data path accessed by the traditional core network can be established at the same time. 3 is a schematic diagram of a data path of local access and traditional core network access in the prior art. As shown in FIG. 3, for a locally accessed connection, a local access data path is from a terminal to a wireless side network element to a local access gateway (L). -SGW, L-PGW and L-GGSN), data transmission does not go through the core network. In order to achieve local access of the terminal to other IP devices or the Internet of the home network, two connections can be established. The first local access data path is used for direct access to the Internet (Internet IP connection, ie SIPTO connection), the second local access The data path is used to directly access other IP devices on the home network (home network IP connection, ie LIPA connection).

In the R10 phase, the wireless side network element (for example, the home base station) and the core network network do not provide local access mobility support. That is, when the user moves out of the base station supporting the local access service, the local access connection needs to be released. In the R11 phase, the wireless side network element and the core network network provide local access mobility support, that is, when the user moves within the same local home base station network (LHN, Local H(e)B Network), the local maintenance can be maintained. Access to the connection ensures that the business is not interrupted. Therefore, the local access mobility is handled differently for different versions of the wireless side network element and the network device. When there is a hybrid network in the wireless network deployment, for example, the wireless network deploys both the R11 home base station and the R10 home base station. The core network cannot identify whether the home base station supports the local access mobility capability, and thus cannot provide corresponding users. Local access to the business. Similarly, the home base station cannot handle the corresponding local core mobility because it cannot identify the core network capabilities of different versions.

The home base station indicates whether it supports the local access mobility by carrying the version information of the home base station. If the version information carried is the R10 version, the home base station is the R10 version of the home base station, and the local access mobility is not supported. If the information is in the R11 version, the home base station is the R11 version of the home base station, which can support local access mobility. The home base station indicates that it is the R11 version of the home base station by carrying the local network identifier (LHN-ID), and supports the local base station. Access mobility.
