Patent ID: 8346271

Claim:
A method for implementing a business of communication service level based on a calling user request, wherein a related calling terminal and a related called terminal belong to a same network, characterized in that said method includes the following steps: step 1, a calling user initiates a call request, the call request at least includes requirement information for a current communication service level of the user; step 2, a network equipment receives the call request, detects the requirement information for the current communication service level in the call request, determines whether a user-network interface on the calling side has a capability of providing the communication service level; if yes, the network equipment analyzes the requirement information for the current communication service level and utilization status of the network resources and obtains strategy information relevant to the communication service level of the current call according to the analysis result, and the step 4 is executed; if no, the next step is executed, wherein said strategy information relevant to the communication service level of the current call includes a calling acceptance priority, or an encoding rate of voice or video media, or a transmission priority of communication packets, or a discarding order, or any combination of above information; step 3, the network equipment doesn't respond to the requirement information for the current communication service level, and the step 5 is executed; step 4, the network equipment allocates a user-network resource for the calling side according to the strategy information relevant to the communication service level of the current call, and the next step is executed; step 5, the calling terminal and the called terminal establish a call connection according to the allocated network resource; wherein a way of reporting the user's requirement information for the current communication service level in the call request initiated by said calling user is additionally dialing an access number prefix before a called number, or a way of reporting the user's requirement information for the current communication service level in the call request initiated by said calling user is that the user configures the current communication service level by a menu or a button which is set on the terminal and can be used to configure the communication service level, and the terminal reports the requirement information for the current communication service level to the network equipment by an interface signaling on the user-network interface after the first configuration or the change of the current configuration.
