Embodiment Construction
[0023] In order to solve the disadvantages of the existing technical solutions, the present invention further elaborates a method for flexibly configuring route redirection according to the present invention through the following examples. The specific implementation will be described in detail below, but not as a limitation of the present invention.
[0024] In the present invention, the access network sends one or more access network identifiers, and provides the PersonalityIndex or protocol set identification PSI supported by the access network corresponding to the access network identifier, so that the terminal can select from multiple access networks Select an access network that the terminal can connect to in the identification, and use the characteristic index PersonalityIndex or the protocol set to identify the PSI to create a route.
[0025] The present invention provides a method for flexibly configuring the routing redirection function, specifically as follows:

The invention provides a method for flexibly configuring redirection of a router, comprising the following steps: an access network sends an access network message which can be used for the redirection, and the access network message includes at least one access network mark and a message needed by an access network which corresponds to the access network marks and establishes a router; an access terminal selects the access network corresponding to one of the access network marks as a redirection access network to carry out redirection processing according to the access network marks of the access network message and establishes the router according to the message needed by establishing the router and the redirection access network, and if the redirection is failed, the access terminal selects an access network corresponding to other access network marks for redirection. The method can effectively solve the problems that the redirection is failed or the redirection router can not be effectively established, thereby enhancing the success ratio of a redirection function and improving the performance of the whole system.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a method for flexibly configuring route redirection. Background technique [0002] In the Ultra Mobile Broadband (UMB: Ultra Mobile Broadband) wireless communication system, routing is used to manage and operate the air interface protocol stack. routing between incoming networks. Routing is a protocol stack used for air interface interaction between the access terminal and the access network. The route is determined according to the protocol type included in the Personality Index or Protocol Set Identifier (PSI for short) supported by both the access terminal and the access network. [0003] When the access terminal detects that a route with a certain access terminal needs to be established, the access terminal sends a route open request message to the access network, requesting to open a route between them. If the access network accepts the request of the access terminal...
