AAA服务器。家用基站是一种小型、低功率的基站，部署在家庭及办公室等室内场所，主要作用是为了给用户提供更高的业务速率并降低使用高速率服务所需要的费用，同时弥补已有分布式蜂窝无线通信系统覆盖的不足。家用基站的优点是实惠、便捷、低功率输出、即插即用等。家用基站可以直接连接到核心网络，如图 la所示；家用基站也可以通过家用基站网关这个逻辑网元接入到核心网络，如图 lb或图 lc所示。在家用基站系统里，无线侧网元是家庭基站。其中，家用基站网关主要功能为：验证家用基站的安全性，处理家用基站的注册，对家用基站进行运行维护管理，根据运营商要求配置和控制家用基站，负责交换核心网和家用基站的数据。图 la、图 lb或图 lc中，核心网网关可以是 SGW、 PGW、服务 GPRS支持节点 ( SGSN, Serving GPRS Support Node) 网关 GPRS支持节点（GGSN， Gateway GPRS Support Node), 其中， GPRS指通用无线分组业务。除了支持移动核心网络的接入以外，移动通信系统（包括家用基站系统）还可支持 IP分流功能（包括本地 IP访问（Local IP Access, 简称为 LIPA) 和选择性 IP传输分流（Selected IP Traffic Offload, 简称为 SIPTO))，在无线侧网元具备 IP分流能力以及用户签约允许 IP分流的条件下，实现终端对家用网络其他 IP设备、企业网络中的 IP设备或者互联网络的本地接入。通过 IP分流功能，可以降低核心网负荷，数据传输便捷高效。为了实现 IP分流功能，增设了本地网关，如图 la、图 lb、图 lc所示。本地网关的增设可提供对 IP分流技术的有力支持，本地网关作为本地接入到外部网络（例如 Internet) 的网关，提供地址分配、计费、分组包过滤、策略控制、数据分流功能、 NAS/S1-AP/RANAP (Radios Access Network Application Part, 无线接入网应用部分） /GTP (General Tunneling Protocol, 通用隧道协议） /PMIP (Proxy Mobile IP, 代理移动 IP协议） /MIP (Mobile IP, 移动

IP设备或者互联网络的本地接入，可以建立两条连接，第一条 IP分流连接数据路径直接访问互联网，即：互联网本地 IP访问连接。第二条 IP分流连接访问数据路径直接访问家用网络其他 IP设备，即：家用网络本地 IP访问连接。 IP分流也可以通过在无线侧网元或家用基站网关或本地网关上增设 NAT地址转换功能来实现，不限于通过不同连接来同时实现核心网访问以及 IP分流的访问功能。在现有技术中，允许终端在移动时享受不间断 IP分流业务的家用基站，组成了一个本地网络，拥有一个本地网络的标识。终端在移动过程中， IP分流连接只允许在相同的本地网络内或者相同的网关覆盖范围下保持业务连续性（本发明中将一个本地网络或者相同的网关覆盖范围，称为 IP分流连接的移动性支持区域）。当终端移动出本地网络或者在不同的本地网络间移动时应释放该 IP分流连接，但是其他业务可能仍然可以保持连续。因此当终端的位置发生变化时，移动通信系统需要判断终端是否移动出了 IP分流连接的移动性支持区域，从而正确处理终端不同的业务。但是，相关技术中对如何进行该判断、由哪个网元进行该判断尚无解决方案。发明内容本发明提供了一种 IP分流连接的处理方法及装置，以解决相关技术中如何判断终端是否移动到

Serving Gateway) , Packet Data Network Gateway (PGW) Home Subscriber Server (HSS, Home Subscriber Server) 3 GPP Authentication Authorization and Accounting (AAA), Policy and Charging Rules Function (PCRF, Policy) And Charging Rules Function) The entity and other supporting nodes. Among them, P-GW is also called PDN GW, and PDN refers to packet data network, which is represented by Packet Data Network. FIG. 1a is a schematic diagram of an EPS system architecture according to the related art. As shown in FIG. 1a, 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 core network gateway includes an SGW and a PGW, and the SGW is a core network serving gateway, which is an access gateway device connected to the E-UTRAN, and forwards data between the E-UTRAN and the PGW, and is responsible for buffering the paging waiting data; The core network access gateway is a border gateway between the EPS and the PDN network, and is responsible for PDN access and forwarding data between the EPS and the PDN. The authentication authorization server includes an HSS, a 3GPP AAA server. 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 affordable, convenient, low power output, plug and play, and more. The home base station can be directly connected to the core network, as shown in FIG. 1; the home base station can also access the core network through the logical base unit of the home base station gateway, as shown in FIG. 1b or FIG. In a home base station system, the wireless side network element is a home base station. 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, performing operation and maintenance management on the home base station, configuring and controlling the home base station according to the operator's requirements, and exchanging data of the core network and the home base station. In Figure la, Figure lb or Figure lc, the core network gateway may be a SGW, a PGW, a Serving GPRS Support Node (SGSN), a Gateway GPRS Support Node (GGSN), where GPRS refers to a general-purpose wireless Grouping business. In addition to supporting access to the mobile core network, mobile communication systems (including home base station systems) can also support IP offloading functions (including Local IP Access (LIPA) and Selective IP Traffic Offload). , referred to as SIPTO)), under the condition that the wireless side network element has IP offload capability and the user subscribes to allow IP offloading, realizing local access of the terminal to other IP devices in the home network, IP devices in the enterprise network, or the Internet. Through the IP offload function, the core network load can be reduced, and data transmission is convenient and efficient. In order to implement the IP offload function, a local gateway is added, as shown in Figure la, Figure lb, and Figure lc. The addition of a local gateway can provide strong support for IP offloading technology. The local gateway acts as a gateway for external access to an external network (such as the Internet), providing address allocation, billing, packet filtering, policy control, data offloading, NAS/ S1-AP/RANAP (Radios Access Network Application Part) / GTP (General Tunneling Protocol) / PMIP (Proxy Mobile IP) / MIP (Mobile IP, Mobile IP) Protocol) Message parsing, NAT (Network Address Translation), IP offload policy routing and execution. The local gateway may be set up in the vicinity of the wireless side network element in the external side network element or in the external mode; or may be set in the vicinity of the home base station gateway in combination with the home base station gateway or in an external manner. The local gateway may be a local SGW (L-SGW, Local SGW), a local PGW (L-PGW, Local PGW), a virtual SGW (V-SGW, Virtual SGW), a virtual PGW (V-PGW, Virtual PSGW), a local GGSN ( L-GGSN, Local GGSN) The external offload gateway can also be a data offload function entity. The local gateway can be combined with the core network gateway (for example, the SGW is moved down and the local gateway is set up), or can be separated from the core network gateway. As shown in FIG. 2a and FIG. 2b, the data flow path of the IP offload connection and the traditional core network IP connection in the mobile communication network architecture is shown. For users who support IP offload connections, a traditional core network IP connection data path and an IP offload connection data path can be established. Figure 2a shows the data flow path of the IP offload connection and the traditional core network IP connection in the UTRAN system. Figure 2b shows the data flow path of the IP offload connection and the traditional core network IP connection in the E-UTRAN system. As shown in FIG. 2a and FIG. 2b, the IP offload data path is: From the terminal to the radio side network element and/or the home base station gateway to the local gateway, the data transmission does not pass 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 IP split connection data path directly accesses the Internet, namely: Internet local IP access connection. The second IP offload connection access data path directly accesses other IP devices on the home network, namely: Home network local IP access connection. IP split can also pass The NAT address conversion function is implemented on the wireless side network element or the home base station gateway or the local gateway, and is not limited to the core network access and the IP offload access function through different connections. In the prior art, a home base station that allows a terminal to enjoy an uninterrupted IP offload service while moving, constitutes a local network and has an identity of a local network. During the mobile process, the IP offload connection only allows service continuity within the same local network or the same gateway coverage (in the present invention, a local network or the same gateway coverage, called IP offload connection movement) Sexual support area). The IP offload connection should be released when the terminal moves out of the local network or moves between different local networks, but other services may still remain contiguous.

The implementation process of the embodiment of the present invention will be described in detail below with reference to examples. The following embodiment of the present invention takes the E-UTRAN system as an example to describe a flow related to determining the mobility determination information of the target radio side network element and determining the mobility support area of the IP offload connection. All embodiments of the invention are applicable to UTRAN/GERAN access networks as well as home base station systems. If the UTRAN system is connected, the core network gateway is a GGSN. If the E-UTRAN system is accessed, the core network gateway refers to the core network serving gateway S-GW and the core gateway access gateway P-GW. The access system is different, the message is different, but the effect Similarly, it does not affect the description of the invention. The processes are all well known to those skilled in the art and will not be described herein. The wireless side network element may be a base station, a home base station, an RNC, a offload gateway, a offload function entity, and a home base station gateway. The mobility management entity may be an MME, an MSC, or an SGSN. IP offloading can be local IP access to the user's local network, local IP access to the company's local network, local IP access to the Internet, Internet traffic shunting, and specific IP data offloading. In the present invention, the mobility determination information refers to the LHN (local H(e)B Network, local home base station network) information, and specifically includes the following content, but is not limited to the following: the LHN identifier of the local network to which the wireless side network element belongs, Or the local gateway address of the radio side network element service, or the local network LHN name of the radio side network element, or the radio side network element address, or the radio side network element identifier. In the present invention, the meaning of the IP offload connection indication is: the connection type of the specific IP offload connection, the connection type is local IP access user local network connection, local IP access company local network connection, local IP access internet connection, internet service The shunt operation connection, the specific IP data offload connection. Or, whether it is an IP split connection. The preferred embodiment 1 is applicable to the EPS access system X2 handover process, in which the source radio side network element sends the LHN information to the target radio side network element. 4 is a flow chart of X2 switching according to a preferred embodiment of the present invention. As shown in FIG. 4, the following steps S402 to S420 are included. Step S402, the terminal has an IP offload connection after accessing the wireless communication system. The source radio side network element finds that the current cell is not suitable for user access according to the measurement report, and then selects a suitable target radio side network element to perform user switching. At this time, the source radio side network element decides to initiate the X2 handover process. The source radio side network element directly sends a handover request message to the target radio side network element, where the message carries the LHN information and the IP offload connection indication. When the LHN information is the source radio side network element address or the source radio side network element identifier, optionally, the source radio side network element uses the source radio side network element address or the source radio side network element identifier to provide a domain name service (Domain Name Server, referred to as DNS) The Home/Node Management System (HMS) query, obtain the LHN identifier of the local network to which the source wireless side network element belongs, or the local gateway address serving the source wireless side network element, or The local network LHN name to which the source wireless side NE belongs. Then, the source radio side network element sends the information queried by the DNS/HMS to the target radio side network element as the LHN information. The IP offload connection indication may be implemented by a newly defined field, or may be implemented by adding an existing field (such as a correlation ID) and adding the field to the message. Step S404: The target radio side network element determines, according to the IP offload connection indication, which connections are IP offload connections, and for the IP offload connection, performs mobility determination according to the LHN information, that is, determines whether the user will move out of the mobility support range of the IP offload connection. If the mobility support range of the IP offload connection is removed, it is determined that the IP offload connection does not support mobility, otherwise mobility is supported. When the LHN information is the LHN identifier of the local network to which the source radio side network element belongs, or the local gateway address served by the source radio side network element, or the local network LHN name of the source radio side network element, the target radio side network element is compared. Whether the LHN information belongs to the LHN identifier to which it belongs, or the local gateway address served by the target radio side network element, or the local network LHN name of the target radio side network element. If they are consistent, it is determined that the user has not moved out of the IP offload connection. Mobility support range, that is, IP offload connection supports mobility. Otherwise, it is determined that the user moves out of the mobility support range of the IP offload connection, that is, the IP offload connection does not support mobility. When the LHN information is the source radio side network element address or the source radio side network element identifier, the target radio side network element uses the source radio side network element address or the source radio side network element identifier to query the DNS server/HMS to obtain the source wireless. The LHN identifier of the local network to which the side network element belongs, or the local gateway address served by the source radio side network element, or the local network LHN name to which the source radio side network element belongs. Then, the target radio side network element compares the information queried by the DNS/HMS with the LHN identifier to which it belongs, or the local gateway address served by the target radio side network element, or the local network LHN name of the target radio side network element. If it is consistent, it is determined that the user does not move out of the mobility support range of the IP offload connection, that is, the IP offload connection supports mobility. Otherwise, it is determined that the user moves out of the mobility support range of the IP offload connection, that is, the IP offload connection does not support mobility. When the result of the determination in step S404 is that the user does not move the mobility support range of the IP offload connection, that is, the IP offload connection supports mobility, step S406a is performed. Otherwise, steps S406b-310b are performed. In step S406a, the result of the determination in step S404 is that the user does not move out of the mobility support range of the IP offload connection, that is, when the IP offload connection supports mobility, according to the prior art, the subsequent process of performing the X2 handover is continued, and the IP offload is activated/established/updated. Connect, complete the X2 switching process. In step S406b, the result of the determination in step S404 is that the user moves out of the mobility support range of the IP offload connection, that is, when the IP offload connection does not support the mobility, the target radio side network element returns a handover confirmation message, and the message carries the IP that cannot be reserved for resource reservation. The bearer connection bearer information, that is, initiates the deletion/release of the IP offload connection. If the user only has an IP offload connection, the shell 1" returns a handover failure message to the source radio side network element. Step S408b: The source radio side network element initiates a bearer release procedure to the local gateway, and releases the unreachable IP offload connection. The source radio side network element sends a bearer release request to the local gateway. Step S410b: The local gateway sends a delete bearer request to the mobility management entity, and the message is forwarded to the mobility management entity by the S-GW. Step S412b to step S414b, the mobility management entity initiates deletion of the radio resource. Step S416b, the mobility management entity responds to the bearer deletion response to the local gateway. Step S418b: The local gateway responds to the bearer release response to the source radio side network element. In step S420b, according to the prior art, the subsequent process of the X2 handover is continued, and the X2 handover procedure is completed. When the result of the determination in step S404 is that the user moves out of the mobility support range of the IP offload connection, that is, the IP offload connection does not support mobility, in addition to the implementation method of step S406b to step S420b proposed in this embodiment, there is another method. . In this method, the target radio side network element always returns a handover failure message to the source radio side network element regardless of whether the user has a connection other than the IP offload connection that can be successfully established in the target. The source radio side network element needs to reselect the target radio side network element at this time, and then initiates the handover again. Preferred Embodiment 2 The preferred embodiment 2 is applicable to the EPS access system S1 handover process, in which the source wireless side network element will

The LHN information is brought to the target radio side network element through the Container field in the handover message. FIG. 5 is a flowchart of S1 handover according to a preferred embodiment 2 of the present invention. As shown in FIG. 5, the following steps S502 to S518 are included. Step S502, the terminal has an IP offload connection after accessing the wireless communication system. The terminal reports the measurement report to the source radio side network element. Step S504: The source radio side network element finds that the current cell is not suitable for user access according to the measurement report, and then selects a suitable target radio side network element to perform user switching. Step S506, the source radio side network element decides to initiate the S1 handover procedure. The source radio side network element sends a handover request message to the mobility management entity, where the message carries the bearer information that needs to be reconstructed on the target side, including the bearer information of the IP offload connection. The container field in the message carries the LHN information. When the LHN information is the source radio side network element address or the source radio side network element identifier, the source radio side network element may use the source radio side network element address or the source radio side network element identifier to query the DNS server/HMS. The LHN identifier of the local network to which the source radio side network element belongs, or the local gateway address serving the source radio side network element, or the local network LHN name to which the source radio side network element belongs. Then, the source radio side network element sends the information queried by the DNS/HMS to the target radio side network element as the LHN information. Step S508, the mobility management entity forwards the handover request to the target radio side network element, where the message carries the bearer information that needs to be reconstructed on the target side, including the bearer information of the IP offload connection. The container field in the message carries the LHN information, and the IP shunt connection indication is carried in the message. The IP offload connection indication may be implemented by a newly defined field, or may be implemented by adding an existing field (such as a correlation ID) and adding the field to the message. Step S510: The target radio side network element determines, according to the IP offload connection indication, which connections are IP offload connections, and for the IP offload connection, performs mobility determination according to the LHN information, that is, determines whether the user will move out of the mobility support range of the IP offload connection. If the mobility support range of the IP offload connection is removed, it is determined that the IP offload connection does not support mobility, otherwise mobility is supported. When the LHN information is the LHN identifier of the local network to which the source radio side network element belongs, or the local gateway address served by the source radio side network element, or the local network LHN name of the source radio side network element, the target radio side network element is compared. Whether the LHN information belongs to the LHN identifier to which it belongs, or the local gateway address served by the target radio side network element, or the local network LHN name of the target radio side network element. If they are consistent, it is determined that the user has not moved out of the IP offload connection. Mobility support range, that is, IP offload connection supports mobility. Otherwise, it is determined that the user moves out of the mobility support range of the IP offload connection, that is, the IP offload connection does not support mobility. When the LHN information is the source radio side network element address or the source radio side network element identifier, the target radio side network element uses the source radio side network element address or the source radio side network element identifier to query the DNS server/HMS to obtain the source wireless. The LHN identifier of the local network to which the side network element belongs, or the local gateway address served by the source radio side network element, or the local network LHN name to which the source radio side network element belongs. Then, the target radio side network element compares the information queried by the DNS/HMS with the LHN identifier to which it belongs, or the local gateway address served by the target radio side network element, or the local network LHN name of the target radio side network element. If it is consistent, it is determined that the user does not move out of the mobility support range of the IP offload connection, that is, the IP offload connection supports mobility. Otherwise, it is determined that the user moves out of the mobility support range of the IP offload connection, that is, the IP offload connection does not support mobility. When the result of the determination in step S510 is that the user does not move out of the mobility support range of the IP offload connection, that is, the IP offload connection supports mobility, step S512a is performed, otherwise steps S512b to S518b are performed. In step S512a, the result of the determination in step S510 is that the user does not move out of the mobility support range of the IP offload connection, that is, when the IP offload connection supports mobility, according to the prior art, the subsequent process of performing the S1 handover is continued, and the IP offload is activated/established/updated. Connect, complete the S1 switching process. In step S512b, the result of the determination in step S510 is that the user moves out of the mobility support range of the IP offload connection, that is, when the IP offload connection does not support the mobility, the target radio side network element returns a handover request acknowledgement message, and the message does not carry the bearer of the IP offload connection. Information, that is, initiates the deletion/release of the IP offload connection. Step S514b, the mobility management entity initiates a release process of the IP offload connection. Step S516b, the mobility management entity returns a handover command message to the source radio side network element. In step S518b, according to the prior art, the subsequent process of the S1 handover is continued, and the S1 handover procedure is completed. When the result of the step S510 is that the user moves out of the mobility support range of the IP offload connection, that is, the IP offload connection does not support the mobility, in addition to the implementation methods of the steps S512b to S518b proposed in this embodiment, there is another method. . In this method, the target radio side network element always returns a handover failure message to the source radio side network element regardless of whether the user has a connection other than the IP offload connection that can be successfully established in the target. The source radio side network element needs to reselect the target radio side network element at this time, and then initiates the handover again.

Step S602 to step S606 are the same as steps S502 to S506. Step S608, the source mobility management entity forwards the relocation request to the target mobility management entity. The message carries the LHN information and the IP offload connection indication. The IP offload connection indication may be implemented by a newly defined field, or may be implemented by adding an existing field (such as a correlation ID) and adding the field to the message. Steps S610 to S612 are the same as steps S508 to S510. Step S614a is the same as step S512a. Step S614b, the result of the step S612 is that the user moves out of the mobility support range of the IP offload connection, that is, when the IP offload connection does not support the mobility, the target radio side network element returns a handover request acknowledgement message, and the message does not carry the bearer of the IP offload connection. Information, that is, initiates the deletion/release of the IP offload connection. Step S616b: The target mobility management entity forwards the relocation response to the source mobility management entity, where the message does not carry the bearer information of the IP offload connection. Step S618b, the source mobility management entity initiates a release process of the IP offload connection. Step S620b: The source mobility management entity returns a handover command message to the source radio side network element. In step S622b, according to the prior art, the subsequent process of the S1 handover is continued, and the S1 handover procedure is completed. When the result of the determination in step S612 is that the user moves out of the mobility support range of the IP offload connection, that is, the IP offload connection does not support mobility, in addition to the implementation methods of step S614b to step S622b proposed in this embodiment, there is another method. . In this method, the target radio side network element always returns a handover failure message to the source radio side network element regardless of whether the user has a connection other than the IP offload connection that can be successfully established in the target. The source radio side network element needs to reselect the target radio side network element at this time, and then initiates the handover again.
