Problems solved by technology

[0004] After the calling terminal initiates a call, the SCP determines that the calling terminal has subscribed to the CNAP service. At this time, regardless of whether the calling terminal is willing to send the calling information, the SCP will send the calling information to the called terminal; in addition, the SCP is through USSD / SMS Sending caller information by means of USSD / SMS messages. When sending USSD / SMS messages, it will occupy mobile phone and signaling resources, which may cause the call to fail. At the same time, USSD / SMS messages can only carry text and pictures, and when carrying too much information, it will take up more mobile phone and signaling resources, which slows down its own sending speed or may fail to send successfully, and also affects normal calls

Embodiment 1

[0032] Wherein, the calling terminal will provide the calling user with an interface for the calling user to choose whether to send calling information. After the calling user makes a selection, the selection result is indicated by a sending instruction, carried in the call signaling and sent out.

[0033] Step 102: judge whether the calling terminal needs to send calling information according to the sending instruction, if it needs to send calling information, then perform step 103; if it does not need to send calling information, then perform step 104;

[0034] After receiving the call signaling sent by the calling terminal, it can be determined according to the content of the sending instruction whether the calling user needs to send calling information.

[0035] Step 103: Carry the calling information of the calling terminal in the call signaling, and send the calling signaling carrying the calling information to the called terminal.

[0036] Step 104: Perform normal call...

Embodiment 2

[0041] Step 202: Fill in the CNAP in the from field name part of the INVITE signaling, that is, the from field in the INVITE signaling carries the sending instruction of the calling information, and sends the signaling carrying the sending instruction of the calling information to the calling user A's CSCFa (Call Session Control Function, call session control function) server;

[0042] Step 203: CSCFa forwards the signaling carrying the caller information sending instruction to the SCP;

[0043] Step 204: After receiving the signaling, the SCP determines that calling user A needs to send calling information, then carries the calling information in the body of the INVITE signaling, and returns the INVITE signaling to CSCFa, wherein the calling user A needs to send calling information. Call information adopts MIME (Multipurpose Internet Mail Extensions, Multipurpose Internet Mail Extensions) encoding method or MMS (Multimedia Messaging Service, Multimedia Information Service) en...

Embodiment 3

[0052] A judging module 302, configured to judge whether the calling terminal needs to send calling information according to the sending instruction;

[0053] The sending module 303 is used to receive the judgment result of the judging module. If the judging result is that the calling terminal needs to send calling information, the calling information of the calling terminal is carried in the call signaling, and the call carrying the calling information The signaling is sent to the called terminal.

[0054] The receiving module 301 is specifically used for:

[0055] The INVITE signaling forwarded by the calling terminal through the calling session control function server is received, and the from field in the INVITE signaling carries a sending instruction of calling information.

[0056] The sending module 303 is specifically used for:

[0057] The calling information of the calling terminal stored locally is carried in the body of the INVITE signaling, and the INVITE signal...

Abstract

The invention discloses a calling method and system for providing calling information and a service control point, belonging to the field of communication. The method comprises the steps of: receiving a calling signaling of a calling terminal, wherein the calling signaling carries a sending indication carrying the calling information; judging whether the calling terminal needs to send the calling information according to the sending indication; and if yes, carrying the calling information of the calling terminal in the calling signaling, and sending the calling signaling carrying the calling information to a called terminal. The service control point comprises a receiving module, a judging module and a sending module. The system comprises the calling terminal, the called terminal and a network side. Through carrying the calling information in the calling signaling, additional cellphones and signaling resources are not occupied, influence to the conservation is avoided, and the carried calling information is more abundant.

Description

technical field [0001] The invention relates to the communication field, in particular to a calling method, system and service control point for providing caller information. Background technique [0002] The CNAP (Calling Name Presentation) service is an intelligent service of the wireless intelligent network. This kind of service is that when the user applies for this service, he can submit a comparison table of number and calling information to the business department. After the number and the corresponding calling information are input into the mobile communication system, if a certain user calls said user, when the call is connected and rings, the caller's caller information will be displayed on the called user's mobile phone or terminal. [0003] The CNAP service has been provided in the narrowband service, and has many different functions. The calling method for providing calling information in the prior art is as follows: when the calling user calls the called user...
