Embodiment 1

[0064] This preferred embodiment 1 is applicable to the handover process of the EPS access system X2. In this process, the source radio side network element sends LHN information to the target radio side network element.

[0065] Figure 4 It is a flow chart of X2 switching according to the preferred embodiment 1 of the present invention, such as Figure 4 As shown, the following steps S402 to S420 are included.

[0066] In step S402, the terminal has an IP offload connection after accessing the wireless communication system. The source wireless 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 wireless side network element to perform user handover. At this time, the source wireless side network element decides to initiate the X2 handover procedure. The source wireless side network element directly sends a handover request message to the target wireless side network elemen...

Embodiment 2

[0084] This preferred embodiment 2 is applicable to the handover process of the EPS access system S1, in which the source radio side network element sends the LHN information to the target radio side network element through the Container field in the handover message.

[0085] Figure 5 It is a flow chart of S1 handover according to the second preferred embodiment of the present invention, such as Figure 5 As shown, the following steps S502 to S518 are included.

[0086] In step S502, the terminal has an IP offload connection after accessing the wireless communication system. The terminal reports the measurement report to the network element on the source wireless side.

[0087] In step S504, the source wireless 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 wireless side network element to perform user handover.

[0088] In step S506, the source wireless side network ...

Embodiment 3

[0102] This preferred embodiment 3 is applicable to the S1 handover process of the change of the mobility management entity of the EPS access system. In this process, the source radio side network element sends the LHN information to the target radio side network element through the Container field in the handover message.

[0103] Figure 6 It is a flow chart of S1 handover according to the third preferred embodiment of the present invention, such as Figure 6 As shown, the following steps S602 to S622 are included.

[0104] Step S602 to step S606 are the same as step S502 to step S506.

[0105] Step S608, the source mobility management entity forwards the relocation request to the target mobility management entity. The message carries LHN information and IP offload connection indication. Wherein, the indication of the IP distribution connection can be realized through a newly defined field, or can be realized by adding the field in the message by borrowing an existing fie...

Abstract

The present invention provides a method and device for processing IP offload connection, the method comprising: the target wireless side network element receives LHN information and / or IP offload connection indication from the source wireless side network element; the target wireless side network element receives the LHN information according to the LHN The information and / or the IP offload connection indication determine whether the terminal moves outside the mobility support area of ​​the IP offload connection; the target wireless side network element processes the IP offload connection according to the judgment result. The invention can guarantee the mobility requirement of the IP distribution service.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a processing method and device for an IP offload connection. Background technique [0002] The Evolved Packet System (EPS, Evolved Packet System) of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) is composed of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), Mobility Management Entity (MME, Mobility Management Entity), Serving Gateway (SGW, Serving Gateway), Packet Data Network Gateway (PGW, Packet Data Network Gateway), Home Subscriber Server (HSS, Home Subscriber Server), 3GPP authentication authorization billing (AAA, Authentication, Authorization and Accounting) server, policy and charging rules function (PCRF, Policy and Charging Rules Function) entity and other supporting nodes. Wherein, the P-GW is also referred to as the PDN GW, and the PDN refers to a packet data n...
