Mobile communication network system for reducing load on core network side, communication control method, and non-transitory computer-readable medium storing program for the method

Abstract

In the detach request signal requesting detachment received from the mobile station UE (27), the mobility management node MME (22) arranged on the core network side for management control of mobile communication omits the detach process on the core network side, and remains The communication session on the core network side set up in the attached mobile terminal is connected between the mobile management node MME (22) and the released mobile station UE (27), and the connection with the mobile station UE (27) and the core network is disconnected. connection, and in the attach request signal received from the mobile station (27) requesting attach, omit the attach process on the core network side, utilize the communication session held by the mobile station (27) on the core network side, and perform unique radio line settings.

Description

technical field [0001] The present invention relates to a mobile communication network system, a communication control method, and a mobile terminal attachment / detachment processing program, and specifically relates to enabling reduction of the core network (core A mobile communication network system, a communication control method, and a mobile terminal attachment / detachment processing program of a load on a node) side. Background technique [0002] In recent years, progress in wireless communication technology has been remarkable, and various standards have been actively established in 3GPP (Third Generation Partnership Project) also on 3G (Third Generation) systems and higher-level mobile communication network systems. In addition, Japanese Unexamined Patent Application Publication No. 2009-246772 "MOBILE MANAGEMENT DEVICEAND RADIO COMMUNICATION BASE STATION DEVICE (Mobile Management Device and Wireless Communication Base Station Device)" of Patent Document 1 and Patent A...

Problems solved by technology

When such requests are generated frequently, it imposes a significant load on the core network and core nodes, and may cause congestion and equipment failure

[0004] Meanwhile, there is also a case where, depending on the application of the terminal such as M2M, location movement is not performed and update of session information is not required every time
