Among other factors, another stimulus is the continuous voice and data communication through wireless media. increased speed and shellfish products. Because of these areas to strengthen communication, wireless communication has been and continues to significantly affect the growing communication to the public. ... ,,, of communication action mention H and Valley types of Mazus through flood system Flood services, which may include, in particular, sip-based services, stream-based (streaming services. Mobile stations usually generate resource reservation requests for data communication services, and control acceptance based on policies determined by policy decision function (Qing) Or reject the resource request, pnp e ^ F 疋 is specifically for the type of service requested by the mobile station. The use of the mobile station related to the policy decision function is based on the request of the resource sender (prafile) and network policy It ’s better to make a policy for the source of action in May. Usually, the policy decision function is not straightforward. User #cognition process. Because the source request from the mobile station is usually received at the packet data service node ψ ^ ^ ^ ^, the PDSN authorizes the request for the resource to the mobile station. Will it: poor policy, policy decision function (PDF). As stated in 97305.doc 200537857, the 'per-policy decision function is a specific service and only does its resource request for the specific type of communication service it processes. Make policy decisions. For example, the mobile station can request the bandwidth configuration of the wireless communication system for the streaming service. The policy control of the bandwidth configuration of the streaming service is handled by a specific policy decision function of the network; -The policy decision function can handle resource requests for another type of communication service (such as SIP-based services). The problem is that the packet data service node usually does not know the type of communication resource request service requested by the mobile station. Therefore, the packet No data service node, knows which policy decision function is connected to process the special type of resource request initiated by the mobile station. This can reduce processing resources Convenience of requests. Another problem is that because the policy decision function needs to obtain the user profile of the requested mobile station to make policy decisions, the policy decisions requested by the PDF to the source of mobile stations may not be directly accessible. The user profile of the mobile station (because PDF does not involve the user authentication process) is hindered. The present invention aims to overcome or at least reduce the impact of one or more of the problems identified above. [Summary of the Invention] In one aspect of the invention, a method in a wireless communication system is provided. The method includes generating a resource request for a communication service, and the resource M includes an identifier that uniquely identifies a type of communication service;忒 The resource request for the flood service. The method further includes selecting a policy control entity to process the resource request, the selection being based at least on the identifier; and performing policy control on the resource request by the selected policy control entity. In another aspect of the invention, a device is provided. The device includes a means for 97305.d0 (200537857) generating a resource request for a communication service, the resource request including an identifier that uniquely identifies a type of communication service; and for receiving the resource request for the communication service The means further comprises means for selecting a policy control entity to process the resource request, the selection being based on at least the identifier m, the means for performing policy control on the resource request by the selected policy control entity. In another aspect of the invention- In the aspect, a wireless communication system is provided. The wireless communication system includes an action for generating a resource request for a communication service. The resource request includes-unique identification-type of communication service identification = payment.
