Mobile communication network system, communication control method, and non-temporary computer-readable medium storing program therefor

Abstract

When a mobile management node MME (22), which is a mobile management node arranged on the core network side to perform management and control of mobile communication, receives a detach request signal from a mobile station UE (27) requesting detachment, the connection between the mobile station UE (27) and the core network is disconnected by omitting the detachment process on the core network side and releasing only the wireless line to the mobile station UE (27), with the core-network-side communication session which was set when the mobile station UE (27) was first attached being maintained as is. Subsequently, when an attach request signal requesting attachment is received from the mobile station (27), the attachment process on the core network side is omitted and only the wireless line is set, with the core-network-side communication session which was maintained for the mobile station (27) being used as is.

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 the 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 DEVICE AND RADIO COMMUNICATION BASE STATION DEVICE (Mobile Management Device and Wireless Communication Base Station Device)" of Patent Document 1 and Paten...

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
