Switching method and device for accessing service network

Abstract

A handover method and device for the ASN are provided in the present invention. The method comprises the steps: establishing a handover path for an ASN handover (601); a terminating network element of the handover path detecting whether the connection of the handover path is abnormal (602); and if it is detected that the connection is abnormal, an abnormal network element in the terminating network element notifying other network elements in the terminating network element to delete the abnormal handover path (603). The present invention effectively ensures the data consistency of data paths between the network elements, enhances the utilization rate of ASN network resources and the transmission efficiency of messages, and is beneficial to dealing with data service. Thus, it settles the problem that, in the handover method for the ASN in the relevant art, there exists the problem of inconsistency in the number of paths on the relevant network elements, which not only leads to the occupation of many ASN network resources, but also results in the loss of data messages, thereby resulting in a failure in data transmission for part of the services of the user, even all of the services of the user.

Description

technical field [0001] The present invention relates to the communication field, in particular to a switching method and device 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 increasingly bright prospects more expansive. [0003] figure 1 Shows the network architecture system 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 (Network Service Provider) is a ...

Problems solved by technology

[0039] The purpose of the present invention is to provide a switching method and device for accessing a service network, which can solve the problem of related problems in Anchor ASN switching, inter-ASN switching, and Serving ASN switching. The problem of the inconsistent number of channels on the ASN network element. The inconsistent number of channels not only occupies more ASN network resources, but also leads to the loss of data packets, resulting in the problem that some services or even the entire service of the user cannot be transmitted.
