Problems solved by technology

[0004] The embodiment of the present invention is to provide a control method, device and system for data transmission of the evolved packet system, which is used to solve the problem that in the prior art, the data needs to go through the P-GW from the local end to the communication pair selection, which increases the time for data transmission. Delay and prone to problems such as single point of failure, routing redundancy, etc.

Embodiment Construction

[0076] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0077] Embodiments of the present invention provide a control method, device, and system for data transmission of an evolved packet system. The evolved packet system EPS is composed of EPC, eNB, and UE. The eNB is responsible for the access network, the UE is the user terminal equipment, and the core network The EPC is composed of MME, S-GW, P-GW, etc. The S-GW is the gateway that terminates the radio interface of the eNB, and the P-GW is the gateway that terminates...

Abstract

Disclosed are a data transmission control method, apparatus and system for an evolved packet system. The method comprises: a local S-GW acquiring an address of a peer P-GW by using an IP address of a communication peer; the local S-GW acquiring an address of a peer S-GW according to the acquired address of the peer P-GW; the local S-GW establishing a bearer with the peer S-GW according to the acquired address of the peer S-GW. In embodiments of the present invention, the local S-GW may acquire the address of the peer P-GW by using the IP address of the communication peer, acquire the address of the peer S-GW according to the address of the peer P-GW, and thereby establishing the bearer between the local S-GW and the peer S-GW, so that the data transmission does not need to use the P-GW, which optimizes routing, reduces the delay, and lowers the probability of communication interruption caused by single point of failure of the P-GW.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a control method, device and system for data transmission of an evolved packet system. Background technique [0002] EPS (Evolved Packet System, Evolved Packet System) consists of three parts: EPC (Evolved Packet Core, Evolved Packet Core Network), base station (eNB, Evolved NodeB) and user equipment (UE, User Equipment). The eNB is responsible for the access network. UE is a user terminal device, and the core network EPC is composed of MME (Mobility Management Entity, Mobility Management Entity), Serving Gateway (S-GW, SeveringGateway), PDN Gateway (P-GW, Packet DataNetwork Gateway, Packet Data Network Gateway), etc. , the S-GW is the gateway that terminates the radio interface of the eNode B, and the P-GW is the gateway that terminates the PDN-oriented SGi interface. If the UE accesses multiple PDNs, the UE corresponds to one or more P-GWs. [0003] In the existin...
