Embodiment 1

[0049] Figure 4 It is a flowchart of a method for establishing a local IP access connection according to Embodiment 1 of the present invention. This example is in figure 1 The system shown and as Figure 2A On the basis of the shown data flow, a method for establishing a local IP access connection is provided, and the method specifically includes the following steps:

[0050] In step S401, the user needs to establish an RRC (Radio Resource Control, radio resource control) connection as a bearer of signaling messages or service data before performing communication.

[0051] In step S402, the user sends an initialization NAS (Non-Access-Stratum, Non-Access Stratum) message to perform an attach operation.

[0052] In step S403, the network element at the wireless side sends the initial user message to the mobility management entity, and forwards the NAS message to the mobility management entity with base station mode information.

[0053] In step S404, the mobility managemen...

Embodiment 2

[0083] Figure 5 It is a flowchart of a method for establishing a local IP access connection according to Embodiment 2 of the present invention. This embodiment applies to figure 1 The system shown and as Figure 2A The scene of the shown data flow, according to the establishment method of the local IP access connection of the second embodiment of the present invention, is mainly used to provide a service request process when the terminal changes from the idle state to the connected state, and its specific steps are described as follows:

[0084] In step S501, the terminal has a local IP access connection after accessing the wireless communication system, and then the terminal enters an idle state.

[0085] In step S502, the terminal initiates a service request to the network element on the wireless side. The radio side network element sends the initial UE message to the mobility management entity.

[0086] Step S503, execute NAS (Non-Access-Stratum, non-access stratum) au...

Embodiment 3

[0098] Figure 6 It is a flowchart of a method for establishing a local IP access connection according to Embodiment 3 of the present invention. This embodiment is mainly applied to the scenario of one SGW and direct tunnel, that is, in such as figure 1 The system shown and as Figure 2B On the basis of the shown data flow (direct tunnel), a method for establishing a local IP access connection is provided, and the method specifically includes the following steps:

[0099] In step S601, the user needs to establish an RRC connection as a bearer of signaling messages or service data before communicating.

[0100] In step S602, the user sends an initialization NAS message to perform an attach operation.

[0101] In step S603, the network element at the wireless side sends the initial user message to the mobility management entity, and forwards the NAS message to the mobility management entity with base station mode information.

[0102] Step S604, the mobility management entit...

Abstract

The invention discloses an establishing method and a device of local (IP) Internet protocol access connection, wherein the establishing method of the local IP access connection comprises: a mobility management entity selects a local gateway according to parameters, wherein the parameters comprise at least one of the following: an identification of a wireless side network element, an identification of a closed subscriber group (CSG) Identification (ID), an identification of position, a tracking area identifier TAI, contract signing information and a connection type; and the mobility management entity establishes the local IP access connection through the local gateway. According to the invention, the mobility management entity selects the local gateway according to the parameters, so that the local IP access connection can be established through the selected local gateway, and the local IP access can be carried out effectively.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for establishing a local IP access connection. 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. T...
