Embodiment 1

[0080] Figure 8 shows that the present invention is figure 1 Based on the system architecture and the scenario where the local access gateway is L-SGW and L-PGW, the flow chart of the service request process when the terminal changes from the idle state to the connected state is provided. S802 to step S826 comprising the following steps:

[0081] Step S802, after the terminal accesses the wireless communication system, it has a local IP access connection and a core network connection, after which the terminal enters an idle state.

[0082] Step S804, the terminal sends a service request message to the mobility management entity via the network element on the radio side.

[0083] Step S806, execute a non-access stratum (Non-Access-Stratum, NAS for short) authentication process (authentication process), this step is optional.

[0084] Step S808, if the CSG identity changes, the mobility management entity judges whether the connected original CSG identity and target CSG ident...

Embodiment 2

[0098] Figure 9 shows that the present invention is figure 1 Based on the system architecture and the scenario where the local access gateway is L-SGW and L-PGW, the flow chart of the terminal location update process is provided. In this embodiment, the original mobility management entity judges whether mobility is supported, and the tracking area update request message carries an activation identifier. The process includes the following steps from S902 to S928:

[0099] Step S902, the terminal sends a tracking area update request message, carrying an activation identifier, to the mobility management entity via the target wireless side network element.

[0100] Step S904, the target mobility management entity sends a context request message to the original mobility management entity, carrying the target CSG identifier.

[0101] Step S906, if the CSG identity changes, the original mobility management entity judges whether the connected original CSG identity and the target C...

Embodiment 3

[0116] Figure 10 shows that the present invention is figure 1 Based on the system architecture and the scenario where the local access gateway is L-SGW and L-PGW, the flow chart of the terminal location update process is provided. In this embodiment, the target mobility management entity judges whether to support mobility, and the tracking area update request message carries an activation identifier. The process includes the following steps from S1002 to S1030:

[0117] Step S1002, the terminal sends a tracking area update request message, carrying an activation identifier, to the mobility management entity via the target wireless side network element.

[0118] Step S1004, the target mobility management entity sends a context request message to the original mobility management entity.

[0119] Step S1006, the original CSG identifier is carried in the context response message sent by the original mobility management entity to the target mobility management entity.

Abstract

The invention discloses a management method for local network protocol access connection and a mobility management entities. The method comprises that: during position update or switching at a terminal, the target mobility management entity receives target CSG (closed subscriber group) identification and / or original CSG identification sent by the original mobility management entity, judges that the local IP access does not support the mobility according to the target CSG identification and / or the original CSG identification, and initiates activation or establishes a core network connection process; or during position update at the terminal, the original mobility management entity receives the target CSG identification sent by the target mobility management entity, judges that the local IP access does not support the mobility according to the target CSG identification and / or the original CSG identification and sends core network connection information to the target mobility management entity, and the target mobility management entity initiates activation or establishes a core network connection process. The method promotes the processing efficiency of a mobile communication system.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for managing local network protocol (Internet Protocol, referred to as IP) access connection and a mobility management entity. Background technique [0002] The Evolved Packet System (EPS) of the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) is composed of the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN), Mobility Management Entity (MME for short), Serving Gateway (S-GW for short), Packet Data Network Gateway (P-GW or PDN GW for short), belonging Subscriber Server (HomeSubscriber Server, HSS for short), 3GPP Authentication, Authorization and Accounting (AAA for short) server, Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF for short) entity and others Composition of support nodes. [0003] figure 1 It...
