Embodiment Construction

[0045] Aiming at the problem that the existing link detection method cannot ensure the security of the IMS core network and the rationality of the load at the same time, an embodiment of the present invention provides a link detection method, the execution subject of the method is an access device, and the process is as follows image 3 As shown, the execution steps are as follows:

[0046] S30: Detect whether the access device has been registered in the IMS core network, if not, go to S31; if it has been registered, go to S34.

[0047] When the access device accesses the IMS network for the first time, the detection result is unregistered.

[0048] S31: Send a link detection message carrying a preset domain name.

[0049] When it is detected that the access device has not been registered in the IMS core network, a link detection message carrying a preset domain name may be sent. The preset domain name can be the default domain name such as the current provincial domain name...

Abstract

The invention discloses a link detection method and access equipment. The method comprises the steps that A) whether the access equipment is registered in the IMS core network is detected, if no, a step B) is turned to, and otherwise, a step E) is turned to; B) a link detection message with a preset domain name is sent; C) whether a response message is received is detected, if no, the step B) is turned to, and otherwise, a step D) is turned to; D) SBC identification information by inquiring the preset domain name is obtained and stored, and a step I) is carried out; E) if SBC identification information of the highest priority is not read, the step B) is carried out, and if SBC identification information of the highest priority is read, a step F) is turned to; F) a link detection message with identification information is sent; G) whether a response message is received is detected, if yes, the step I) is carried out, and otherwise, a step H ) is carried out; H) SBC identification information read in an available SBC list is deleted; and I) the flow is completed. Thus, the network load is reduced, and the network safety is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a link detection method and an access device. Background technique [0002] The Internet Protocol Multimedia Subsystem (IMS) core network mainly includes a Home Subscriber Server (HSS), a Proxy-Call Session Control Function (P-CSCF), an inquiry call session Network elements such as Inquiry-Call Session Control Function (I-CSCF), Service-Call Session Control Function (S-CSCF), Session Border Controller (SBC), etc. Link detection messages (OPTIONS) are periodically sent between elements to determine whether the link between the current network element and the adjacent network elements is normal. Whether the OPTIONS header field is set properly or not will directly affect the load and performance of the IMS core network. safety. At present, there are two main methods of link detection between the access device and the SBC: [0003] First, when multiple SBCs ...
