Problems solved by technology

[0006] based on figure 1 In the scenario of the system architecture, during the handover process of the terminal, if the local IP access connection does not support mobility (for example, the local gateway changes or the CSG identifier does not support mobility), the data of the terminal cannot be transmitted through the target wireless side network element to the original local gateway, which not only leads to waste of resources and increased system processing burden, but also makes it impossible to transmit local IP data
[0007] There is no effective solution to the problem of how to judge whether the local IP access connection supports mobility in related technologies.

Embodiment 1

[0061] Image 6 is the invention in figure 1 The flow chart of the handover process of the terminal based on the system. In this embodiment, the original mobility management entity judges whether mobility is supported according to the local gateway information or closed subscriber group (Closed Subscriber Group, CSG) information, and adds a relocation front Transfer to the confirmation message, the specific steps are described as follows:

[0062] In step S601, the network element on the radio side determines that it is necessary to initiate an S1 handover.

[0063] In step S602, the original wireless side network element sends a handover request to the original mobility management entity.

[0064] Step S603, the original mobility management entity sends a relocation forwarding request message to the target mobility management entity.

[0065] In step S604, the target mobility management entity may initiate a session establishment process of the core network and local IP ac...

Embodiment 2

[0087] Figure 7 is the invention in figure 1 The flow chart of the terminal switching process on the basis of the system. In this embodiment, the original mobility management entity judges whether to support mobility according to the local gateway information or CSG information, and modifies the relocation forwarding completion confirmation message. The specific steps are described as follows:

[0088] In step S701, the network element at the wireless side judges that an S1 handover needs to be initiated.

[0089] In step S702, the original wireless side network element sends a handover request to the original mobility management entity.

[0090] Step S703, the original mobility management entity sends a relocation forwarding request message to the target mobility management entity.

[0091] In step S704, the target mobility management entity may initiate a session establishment process of the core network and local IP access connection to the core network gateway.

Embodiment 3

[0112] Figure 8 is the invention in figure 1 On the basis of the system, the flow chart of the terminal handover process, in this embodiment, the original mobility management entity judges whether to support mobility according to the CSG information, and the specific steps are described as follows:

[0113] In step S801, the network element on the wireless side judges that an S1 handover needs to be initiated.

[0114] Step S802, the original wireless side network element sends a handover request to the original mobility management entity, carrying the target CSG identifier.

[0115] In step S803, the original mobility management entity judges whether mobility is supported.

[0116] The method of judging whether to support mobility is: if the CSG identity changes, the original mobility management entity judges whether the user’s initial CSG identity and target CSG identity belong to the CSG list supporting mobility (if so, it is considered to support mobility) , or, if the...

Abstract

The invention discloses a local IP access connection management method. The access connection management method comprises that whether the local IP access connection supports mobility is determined, if support, then the local IP access connection is processed, wherein the processing includes at least one of activation, establishment and update. According to the invention, an original / target mobility management entity or an original / target wireless side network element determines whether the local IP access connection supports mobility according to CSG (closed subscriber group) identification or local gateway information, so that the management operation to the local IP access connection is realized, the waste of system resources is avoided, processing load is prevented from being increased, and the processing efficiency of the mobile communication system is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for managing local IP access connections. 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), home user Home Subscriber 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 other supports Node composition. [0003] figure 1 It is a schematic diagram of the EPS system architecture according to related technologies. The mobility management e...
