Exit IDLE channel establishment method and exit IDLE channel device for access service network

Abstract

The invention discloses an exit IDLE channel establishment method and an exit IDLE channel establishment device for an access service network. The method comprises the following steps: establishing data channels among net elements of the access service network when a user exits IDLE; detecting whether the data channels are in abnormal connection or not by two-end net elements of the data channels; and if the abnormal connection is detected, informing opposite-end net elements in the two-end net elements to delete the data channels in the abnormal connection by abnormal-end net elements in the two-end net elements. The invention overcomes the difficulty that the exit IDLE channel establishment method for the access service network in the correlative technology is not beneficial to dealing with data business due to the fact that the establishment success rate of the data channel is lower when a plurality of data channels simultaneously are required to be established, further effectively ensures the consistency of the data channels among the net elements of the ASN and increases the resource utilization of BS and AGW and the establishment success rate of the data channels, thereby being beneficial to dealing with the data business.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for establishing an exit IDLE (idle mode) channel for accessing a service network. Background technique [0002] With the development of mobile terminal requirements and the wide application of wireless technology, WiMAX (Worldwide Interoperability for Microwave Access), a wireless metropolitan area network technology based on the IEEE802.16 standard, is developing more and more rapidly, with a brighter future more and more broad. [0003] figure 1 Shows the network architecture diagram of WiMAX, where CSN (ConnectivityService Network) is the connection service network, MS / SS (Mobile Station / SubscriberStation) is the mobile terminal, and ASN (Access Service Network, access service network) is the WiMAX network system A collection of corresponding message flows of functional entities related to access services. ASNs are connected through R4 ports. NSP (N...

AI Technical Summary

Problems solved by technology

[0016] The purpose of the present invention is to provide a method for establishing an exit IDLE channel for accessing a service network, which can solve the problem caused by the BS when multiple data channels need to be established at the same time in the method for establishing an exit IDLE channel for accessing a service network in the related art. The number of data channels on the AGW is inconsistent, resulting in low utilization of BS or AGW resources, and a low success rate of data channel establishment, which is not conducive to engaging in data services
