Abstract

A method, a device and a storage medium for processing a communication service in a circuit switch domain are provided. The method may include: judging, when a communication service being currently processed by a communication terminal is a voice call service or a short message service in a circuit switch domain, whether a switching condition for switching the communication service onto a real-time communication tool in a packet switch domain of the communication terminal is met; if it is met, switching the communication service onto the real-time communication tool in the packet switch domain of the communication terminal.

First claim

What is claimed is:

1. Method for implementing Number Portability Announcement NPA, comprising:
receiving a calling request;
triggering Telephone Number Mapping ENUM to execute an ENUM query and acquiring a query result;
judging whether a callee number generates Number Portability NP according to the query result and acquiring a judgment result; and
sending an announcement instruction to an Media Resource Function Processor MRFP when the judgment result is that the callee number generates the NP, so as to enable the MRFP to announce an NP prompt tone to a caller according to the announcement instruction.

2. The method according to claim 1 , wherein the query result is that callee number information in the calling request is in a Telephone Uniform Resource Identifier TEL URI format; and
the judging whether the callee number generates the NP according to the query result, comprises: judging whether the callee number generates the NP according to the callee number information in the TEL URI format.

3. he method according to claim 2 , wherein the judging whether the callee number generates the NP according to the callee number information in the TEL URI format, comprises:
extracting a network routing code and a user number section in the callee number information in the TEL URI format; querying whether the network routing code is consistent with a pre-configured network routing code corresponding to the user number section in a first corresponding relationship table according to the user number section; if not consistent, it is indicated that the callee number generates the NP; and if consistent, it is indicated that the callee number does not generate the NP.

4. The method according to claim 3 , further comprising: feeding back an error message to a Serving Call Session Control Function SCSCF when the judgment result is that the callee number does not generate the NP.

5. The method according to claim 2 , further comprising: feeding back an error message to a Serving Call Session Control Function SCSCF when the judgment result is that the callee number does not generate the NP.

6. The method according to claim 1 , wherein the query result is that the callee number information in the calling request is in a Session Initialization Protocol Uniform Resource Identifier SIP URI format; and
the judging whether the callee number generates the NP according to the query result, comprises: judging whether the callee number generates the NP according to the callee number information in the SIP URI format.

7. The method according to claim 6 , wherein the judging whether the callee number generates the NP according to the callee number information in the SIP URI format, comprises:
extracting a network domain name and a user number section in the callee number information in the SIP URI format; querying whether the network domain name is consistent with a pre-configured network domain name corresponding to a user number section in a second corresponding relationship table according to the user number section; if not consistent, it is indicated that the callee number generates the NP; and if consistent, it is indicated that the callee number does not generate the NP.

8. The method according to claim 6 , further comprising: feeding back an error message to a Serving Call Session Control Function SCSCF when the judgment result is that the callee number does not generate the NP.

9. The method according to claim 1 , further comprising: feeding back an error message to a Serving Call Session Control Function SCSCF when the judgment result is that the callee number does not generate the NP.

10. A Number Portability Announcement Application Server NPA AS, comprising: a calling receiving module, an execution module, a judgment processing module and a sending module, wherein
the calling receiving module is configured to receive a calling request;
the execution module is configured to trigger Telephone Number Mapping ENUM to execute an ENUM query and acquire a query result;
the judgment processing module is configured to judge whether a callee number generates Number Portability NP according to the query result and acquire a judgment result; and
the sending module is configured to send an announcement instruction to a Media Resource Function Processor MRFP when the judgment result acquired by the judgment processing module is that the callee number generates the Number Portability NP, so as to enable the MRFP to announce the NP prompt tone to the caller according to the announcement instruction.

11. The NPA AS according to claim 10 , wherein the query result is that the callee number information in the calling request is in a Telephone Uniform Resource Identifier TEL URI format; and
the judgment processing module is configured to judge whether the callee number generates the NP according to the callee number information in the TEL URI format.

12. The NPA AS according to claim 11 , wherein the judgment processing module comprises a first extraction unit and a first query unit, wherein
the first extraction unit is configured to extract a network routing code and a user number section in the callee number information in the TEL URI format; and
the first query unit is configured to query whether the network routing code is consistent with a pre-configured network routing code corresponding to the user number section in a first corresponding relationship table according to the user number section, if not consistent, it is indicated that the callee number generates the NP, and if consistent, it is indicated that the callee number does not generate the NP.

13. The NPA AS according to claim 12 , wherein the sending module is further configured to feed back an error message to a Serving Call Session Control Function SCSCF when the judgment result acquired by the judgment processing module is that the callee number does not generate the NP.

14. The NPA AS according to claim 11 , wherein the sending module is further configured to feed back an error message to a Serving Call Session Control Function SCSCF when the judgment result acquired by the judgment processing module is that the callee number does not generate the NP.

15. The NPA AS according to claim 10 , wherein the query result is that the callee number information in the calling request is in a Session Initialization Protocol Uniform Resource Identifier SIP URI format; and
the judgment processing module is configured to judge whether the callee number generates the NP according to the callee number information in the SIP URI format.

16. The NPA AS according to claim 15 , wherein the judgment processing module comprises a second extraction unit and a second query unit, wherein
the second extraction unit is configured to extract a network routing code and a user number section in the callee number information in the SIP URI format; and
the second query unit is configured to query whether the network routing code is consistent with a pre-configured network routing code corresponding to a user number section in a second corresponding relationship table according to the user number section, if not consistent, it is indicated that the callee number generates the NP, and if consistent, it is indicated that the callee number does not generate the NP.

17. The NPA AS according to claim 10 , wherein the sending module is further configured to feed back an error message to a Serving Call Session Control Function SCSCF when the judgment result acquired by the judgment processing module is that the callee number does not generate the NP.
