Abstract
A method and an apparatus for processing a session request in a network are disclosed. For example, the method receives the session request by a Serving-Call Session Control Function (S-CSCF), and sends a query to a tElephone NUmbering Mapping (ENUM) server for the session request. The method determines if a response is received to the query to the ENUM server, and inserts an indication of a component failure in a header of the session request if the response is not received from the ENUM server, wherein the indication of the component failure indicates a non-responsive ENUM server.
Claims20
A method for processing a session request in a network, comprising:
- receiving the session request by a Serving-Call Session Control Function (S-CSCF);
- sending a query to a tElephone NUmbering Mapping (ENUM) server for the session request;
- determining if a response is received to said query to said ENUM server;
- and
- inserting an indication of a component failure in a header of said session request if said response is not received from said ENUM server, wherein said indication of said component failure indicates a non-responsive ENUM server.
A computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform steps of a method for processing a session request in a network, comprising:
- receiving the session request by a Serving-Call Session Control Function (S-CSCF);
- sending a query to a tElephone NUmbering Mapping (ENUM) server for the session request;
- determining if a response is received to said query to said ENUM server;
- and
- inserting an indication of a component failure in a header of said session request if said response is not received from said ENUM server, wherein said indication of said component failure indicates a non-responsive ENUM server.
A method for processing a session request in a network, comprising:
- receiving the session request from a Serving-Call Session Control Function (S-CSCF), wherein said session request comprises an indication of a component failure in a header of said session request, wherein said indication of said component failure indicates a non-responsive ENUM server;
- sending a query to a Home Subscriber Server (HSS) to obtain domain information of a called party of said session request;
- and
- stripping said indication of said component failure in said header from said session request, and routing said session request in accordance with said domain information, if said domain information is received from said HSS.
