Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to the technology that realizes moving back net in a kind of WiMAX communication system.
Background technology
In wireless network, provide the network element of the network side of service can be for certain portable terminal of commencing business for one or more.When terminal is online, for providing the network element of service, terminal can preserve relevant information, when terminal exits network, then need to notify the network element of preserving this terminal related information to move back net operation, in each provides the network element of different access service networks of service for it, all can realize moving back net and handle to guarantee this portable terminal at what this portable terminal carried out.
With the WiMAX communication system is example, for the user provide service flow authorization person that QoS (service quality) and broadband reserve, for the user provides the policy functional entity of terminal storage and distribution services quality assurance information, Accounting Client or the like that charge information is provided for the user when portable terminal is online, can be this terminal storage relevant information.In addition,, need set up corresponding security information, just can carry out communication service safely based on described security information terminal at each terminal for guaranteeing the proper communication between terminal and the communication network.Authentication device as access control point need be preserved some described security information for terminal, and described security information is divided into the authorization key information of the safety alliance information and the chain of command of data surface.
When terminal exits network, for providing these network elements of service, terminal can move back net because can't know this portable terminal, thereby can not in time move back net operation, and it still can preserve the relevant information of invalid terminal correspondence, this is obviously to being a kind of wasting of resources.
At present, when portable terminal moves back net, also do not provide a kind of feasible technical scheme, so that the network element of these storage terminal information when terminal exiting network, can be carried out in time and move back net operation accordingly.
Summary of the invention
The technical problem to be solved in the present invention is to provide and realizes in a kind of WiMAX communication system moving back the method for net, so that can know in time that for terminal provides the network side network element of service the net that moves back of terminal moves back net operation.
The technical problem to be solved in the present invention is achieved through the following technical solutions:
The invention provides the method that realizes moving back net in a kind of WiMAX communication system, may further comprise the steps:
