Embodiment Construction

[0048] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0049] An embodiment of the present invention proposes an automatic configuration method 300 of an S1-MME interface, such as image 3 A flow diagram of this embodiment 300 is shown. The method 300 includes:

[0050] S301. After joining the MME Pool, the newly added MME establishes an S10 interface with the original MME in the MME Pool.

[0051] S302. The newly added MME acquires transport layer address information of the evolved base station ENB covered by the MME Pool area.

[0052] S303. The newly added MME establishes an SCTP association with the ENB according to the transport layer address information of the ENB.

[0053] S304. The ENB detects the availability of...

Abstract

The invention provides a method, a system and a device for automatically configuring an S1-MME interface. The method comprises the steps of: newly adding an MME after an MME Pool is added, establishing an S10 interface with the original MME in the MME Pool; obtaining address information of a transport layer of an evolution base station (ENB) covered by the MME Pool through the newly added MME; establishing a simple control transmission protocol (SCTP) coupling with the ENB by the newly added MME according to the address information of the transport layer of the ENB; detecting the usability of the SCTP coupling by the ENB; and if the SCTP coupling is detected to be useable, then, establishing an application layer connection with the newly added MME by the ENB based on the SCTP coupling. By adopting the method, the system and the device, the automatic configuration of the S1-MME interface under the newly added MME scene can be realized under the traditional network architecture.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to the automatic configuration of the S1-MME interface in the evolution packet system network. Background technique [0002] The system architecture of the Evolved Packet System (EPS, Evolved Packet System) of the 3GPP long-term evolution is as follows figure 1 shown. According to SAE (System Architecture Evolution, System Architecture Evolution) protocol 3GPP TS23.401v8.2.0, the system includes EPC (Evolved Packet Core, Evolved Packet Core Network) and E-UTRAN (Evolved Universal Terrestrial Radio AccessNetwork, Evolved Universal Terrestrial Radio Access Network) into the network). [0003] Wherein, the EPC includes MME (Mobility Management Entity, mobility management entity), SGW (Serving Gateway, serving gateway), PGW (PDN Gateway, PDN gateway) and other network element devices. The MME provides reachability management for the UE (User Equipment, user equipment), i...
