Embodiment Construction
[0040] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0041] Figure 4 A flowchart showing a method for establishing a data channel according to a first embodiment of the present invention, the method includes the following steps:
[0042] Step 401, establishing a data channel between network elements of the ASN;
[0043] Step 402, detecting whether the network elements at both ends of the data channel are abnormally connected;
[0044] Step 403, if an abnormal connection is detected, the abnormal network element of the network elements at both ends notifies the peer network element of the two network elements to delete the data channel with abnormal connection.
[0045] In this embodiment, after the data channel is established by the method of the related art, the established data channel is detected, the data channel with abnormal connection is found, and the network element with ab...

A method and device for establishing a data channel between network elements of the Access Service Network (ASN) are provided. The method includes the following steps: establishing a data channel between network elements of the ASN (401); detecting whether the network elements at both ends of the data channel are abnormally connected (402); if so, the network element at the abnormal end notifies the network element at the opposite end to delete the abnormally-connected data channel (403). The device includes an establishment module, a detection module and a deleting module. The present invention resolves the problem in the relevant art about the data channel establishment of the ASN that when multiple data channels are simultaneously required to be established, the success probability is lower and the implementation of a data service is not facilitated; furthermore, the invention ensures the consistency of the data channel between each network element of the ASN, thereby improving the resource utilization rate of the Base Station (BS) and the ASN Gateway (AGW), increasing the success probability of the data channel establishment, and facilitating the implementation of the data service.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a method and device for establishing a data 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 (Network Service Provid...
