METHOD FOR RESERVING RESOURCE,METHOD FOR PROCESSING CHARGING FAILURE,AND POLICY DECISION POINT

摘要

A method for resource reservation, a method for handling a charging failure and a policy decision point are disclosed. A network element receives a service request of a user, and requests a resource reservation policy from the policy decision point. The policy decision point makes a resource reservation policy according to the account data of the user and returns the resource reservation policy to the network element. The network element executes the resource reservation policy and performs the resource reservation for the user. Because the policy decision point performs the resource reservation according to the account data of the user, the impact on the service provision due to the reason that the prior art does not take the variation in user's account data into consideration may be avoided. The information for resource reservation may be more comprehensive and the resource reservation procedure may be more customer-friendly.
