Method and system for implementing third-party authentication based on gray list

Abstract

The present invention relates to a communication method, comprising: receiving a service request from a requesting party; performing a third-party authentication on the service request according to a gray list and obtaining an authentication result; and processing the service request according to the authentication result. The present invention relates to a communication system, comprising: means for receiving a service request from a requesting party; means for performing a third-party authentication on the service request according to a gray list and obtaining an authentication result; and means for processing the service request according to the authentication result. The present invention implements a third-party control of services based on the gray list, and can effectively manage a variety of services in the communication system.

The method according to  claim 1 , wherein performing the third-party authentication on the service request by selecting a first authenticating party in the IMS network according to a gray list comprises: forwarding the service request from the requesting party to the first authenticating party which authenticates the service request. 
     
     
         4 . The method according to  claim 2 , wherein processing the service request according to the authentication result comprises: providing the service to the requesting party when the authentication result is Accept; and not providing the service to the requesting party when the authentication result is Reject. 
     
     
         5 . (canceled) 
     
     
         6 . The method according to  claim 1 , wherein, performing the third-party authentication on the service request by selecting a first authenticating party in the IMS network according to a gray list comprises: performing an authentication of different service level on the service request. 
     
     
         7 . (canceled) 
     
     
         8 . A communication system including a non-transitory computer-readable storage device storing computer-executable instructions which, when executed by a processor of a computing device in an IP Multimedia System (IMS) network, configure the processor to:
 receive a service request from a requesting party in the IMS network;   perform a third-party authentication on the service request by selecting a first authenticating party in the IMS network according to a gray list and obtaining an authentication result;   process the service request according to the authentication result;   modify a service level granted to the requesting party in response to a request from the first authenticating party in the IMS network;   wherein the processor is further configured to dynamically update the gray list according to the request.   
     
     
         9 . The system according to  claim 8 , wherein the gray list includes at least the following three attributes: requesting party, authenticating party and service. 
     
     
         10 . The system according to  claim 9 , wherein the processor is further configured to perform the third-party authentication on the service request by forwarding the service request from the requesting party to the authenticating party which authenticates the service request. 
     
     
         11 . The system according to  claim 8 , wherein the processor is further configured to process the service request according to the authentication result by:
 providing the service to the requesting party when the authentication result is Accept; and   not providing the service to the requesting party when the authentication result is Reject.   
     
     
         12 . (canceled) 
     
     
         13 . The system according to  claim 8 , wherein the processor is further configured to perform third-party authentication on the service request according to a gray list and obtain an authentication result by performing an authentication of different service level on the service request. 
     
     
         14 . (canceled) 
     
     
         15 . A communication method executed in an application server in an IP Multimedia System (IMS) network, the method comprising:
 receiving a service request from a calling party in the IMS network;   performing an authentication on the service request by selecting a first authenticating party in the IMS network according to a gray list and obtaining an authentication result;   processing the service request according to the authentication result;   modifying a service level granted to the calling party in response to a request from the first authenticating party in the IMS network; and   further comprising dynamically updating the gray list according to the request.   
     
     
         16 . The method according to  claim 1 , wherein performing the third-party authentication on the service request according to a gray list comprises: forwarding the service request from the requesting party to the first authenticating party and to one or more additional authenticating parties which each authenticate the service request. 
     
     
         17 . The method according to  claim 16 , wherein processing the service request according to the authentication result further comprises processing the service request when all of authentication parties have authenticated the service request. 
     
     
         18 . The method according to  claim 16 , wherein processing the service request according to the authentication result further comprises processing the service request when any one of authentication parties have authenticated the service request. 
     
     
         19 . The method according to  claim 16 , wherein processing the service request according to the authentication result further comprises processing the service request when at least two authentication parties have authenticated the service request. 
     
     
         20 .
