Embodiment 1

[0073] This embodiment provides a method for supporting mobile management of multiple APN connections, which can solve a related technical scenario and propose a method for supporting mobile management of multiple APN connections in this scenario.

[0074] The MAG reports the multi-APN address translation capability to the network, and the network sends the corresponding multi-APN connection information to the MAG.

[0075] Preferably, during the initial attachment and / or handover process of the mobile node, the MAG sends a multi-APN address translation capability indication to AAA or MME, and AAA or MME issues corresponding multi-APN connection information and or APN flow selection routing policy information to MAG .

[0076] Preferably, the multi-APN address translation capability includes but is not limited to the service flow identification capability. The corresponding flow is associated with the APN according to the flow strategy. If the currently connected APN is not the APN c...

Embodiment 2

[0079] This preferred embodiment provides a method for sending data streams for multiple APN connections. In this preferred embodiment, the mobile node Figure 4 The process is attached to the network through MAG1, and MAG1 establishes 3 PMIPv6 tunnels and APN binding association relationships for mobile nodes. After the mobile node switches from MAG1 to MAG2, MAG2 completes the capability negotiation described in the present invention during the authentication and authorization process with AAA. The process of this preferred embodiment includes step S802 to step S828.

[0080] Step S802: L3 connection.

[0081] Step S804: PMIPv6 tunnel (mobile node identifier, default APN, HoA-1).

[0082] Step S806: PMIPv6 tunnel (mobile node identifier, default APN, HoA-2).

[0083] Step S808: SIP flow (the source address is changed from HoA-1 to HoA-2 after MAG1).

[0084] Step S810: PMIPv6 tunnel (mobile node identifier, default APN, HoA-3).

[0085] Step S812: HTTP flow (the source address is cha...

Embodiment 3

[0093] The preferred embodiment provides a method for sending data streams of multiple APN connections. In this embodiment, the user equipment is initially attached to the EPC through a trusted WLAN to implement the flow chart of the present invention. In the figure, the TWAN has the multiple APNs described in the summary of the invention. Address translation capability. Picture 9 It is a flowchart used in the initial attachment process when a trusted WLAN is connected to the EPC network according to an embodiment of the present invention, such as Picture 9 As shown, the method includes the following steps S902 to S920.

[0094] Step S902: The user equipment establishes a three-layer connection to the trusted WLAN network.

[0095] Step S904: The user equipment initiates access authentication authorization to the TWAN, and the 3GPP AAA server responds to the access authentication authorization request of the user equipment forwarded by the TWAN. The TWAN includes the multi-APN ad...

Abstract

The invention discloses a multiple access point connection processing method and an apparatus thereof. The method comprises the following steps that a MAG reports a conversion ability of multiple APN addresses to a network; the MAG receives multiple APN connection information which is fed back by the network and corresponds to the conversion ability of multiple APN addresses; the MAG sends a data stream of a mobile node to the plurality of networks according to the multiple APN connection information. By using the method and the apparatus of the invention, a terminal is realized to access the plurality of APNs under the condition that single packet data is connected to an access network.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method and device for processing multiple access points (Access PointName, APN for short) connection. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) evolved packet system (Evolved Packet System, referred to as EPS) from 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 subscriber server (Home Subscriber Server, referred to as HSS), policy and charging rules function (Policy and Charging Rules Function, referred to as PCRF) entity and other supporting nodes. [0003] figure 1 , The MME mobility management unit is responsible for mobility management, non-access stratum signaling pro...
