Signalling connection managing method for interface between radio network controller and core nets

Abstract

The present invention relates to a wireless networks with core network interface signaling connection management method. The present invention includes in core network i.e. SGSN, when determined idle signaling connection existent time exceeds scheduled time-value, then releasing said signaling connection. The present invention provides delay releasing based Iu connection management method in WCDMA system, avoiding releasing Iu connection with handset acting conflict, reducing user activating data service time delay.

Description

technical field [0001] The invention relates to a WCDMA mobile communication system, in particular to a signaling connection management method for an interface between a wireless network controller and a core network. Background technique [0002] In the WCDMA (Wideband Code Division Multiple Access) system, when the user has context signaling to transmit, a signaling message for carrying the signaling message must be established between the user terminal (such as a mobile phone) and the SGSN (Serving GPRS Support Node). order to connect. [0003] Such as figure 1 As shown, in the WCDMA system, the signaling connection is divided into two sections: one section is the RRC (radio resource control) connection on the Uu interface between MS (mobile station) and RNS (radio network subsystem); the other One segment is the Iu connection on the Iu interface between RNS and SGSN. [0004] In the system, when there is no need to transmit signaling messages, the signaling connection...

Problems solved by technology

Therefore, the SGSN will think that there is no business to continue, and will choose to release the Iu connection immediately. However, in fact, the operation of the mobile phone may be to initiate the activation of a new PDP immediately after deactivating each PDP

In this way, the above operation process will cause the mobile phone to issue a new PDP activation request because the Iu connection has been released by the SGSN after the PDP is deactivated, and a new PDP activation request must be re-established. Similarly, this process also increases the time delay for activating data services

[0012] To sum up, according to the current protocol specifications and the uncertainty of mobile terminal implementation, the standby time of the mobile phone is greatly reduced, or the mobile phone needs an additional connection establishment delay when activating the data service, making the delay required for activating the service relatively long. long
