The embodiment of the invention relates to a method and device for processing service parameters, wherein the method comprises the following steps: a calling party CSCF (Call Session Control Function) or BGCF (Breakout Gateway Control Function) receives a first invitation message sent by a calling party AS (Application Server), wherein a Request-URI (Uniform Resource Identifier) field of the first invitation message carries a Tel URI and service parameters of a called party; the calling party CSCF or BGCF obtains SIP (Session Initiation Protocol) URI corresponding to the Tel URI by inquiring a server for storing phone numbers; and next, the calling party CSCF or BGCF sends a second invitation message to the network of the called party so as to page a terminal of the called party, wherein the Request-URI field of the second invitation message carries the SIP URI and the service parameters. The embodiment of the invention can prevent service failure resulted from incorrect carrying of service parameters and ensure the normal operation of communication service.
Description
technical field [0001] The embodiments of the present invention relate to communication technology, and in particular to a method and device for processing service parameters. Background technique [0002] An IP Multimedia Subsystem (IP Multimedia Subsystem, IMS for short) network is a subsystem proposed by the 3rd Generation Partnership Project (3GPP for short) to support IP multimedia services. In the call flow of the IMS network, the application server (Application Server, referred to as AS) can carry the corresponding service parameters in the request universal resource identifier (Request-URI) ) field. [0003] Because in the follow-up process, the calling side may need to query the number server used to store the telephone number, for example: telephone number mapping (Telephone Number Mapping, referred to as ENUM) server, number portability (Number Portability, referred to as NP) server, but the existing The technology does not clarify the processing method of the s...
