Problems solved by technology

[0005] The problem with the prior art is that when a new MME is added, no specific solution is given to solve the problem of how to establish an S1 interface connection; when both ends of the interface connection simultaneously send an interface connection establishment request, the two interface connections are established When request messages collide, no solution is given; no specific interface management scheme is given for the case where an S1 interface or X2 interface supports multiple SCTP couplings

Abstract

The embodiment of the invention discloses a method for establishing and maintaining interface connection, which comprises the following steps that: a first entity sends a request for establishing the interface connection to a second entity; the first entity receives the request for establishing the interface connection sent by the second entity; and the first entity and the second entity establish the interface connection. The embodiment of the invention also discloses a device for establishing and maintaining the interface connection. With method and the device provided by the embodiment, the establishment of the interface connection is more effective, and the storage space and air-interface resources are saved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method and device for establishing and maintaining an interface. Background technique [0002] The Evolved Universal Mobile Telecommunications System Radio Access Network (E-UTRAN) is also called the Long Term Evolution (LTE) network, and the corresponding core network is the System Architecture Evolution (SAE ), the specific content can refer to the protocol 3GPPTS36.300. The evolved base stations (evolved NodeB, eNB) in E-UTRAN are connected through the X2 interface, and the eNB is connected to the core network equipment Mobility Management Equipment / Serving Gateway (MME / S-GW) through the S1 interface . The S1 interface of the E-UTRAN is divided into a control plane interface and a user plane interface, wherein the control plane interface is connected to the MME, which is called S1-MME, and the user plane interface is connected to the S-GW. The cont...
