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 callinginformation 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 carriedcalling information is more abundant.
Description
Technical field
The present invention relates to the communications field, particularly a kind of method of calling, system and service control point that caller information is provided.
Background technology
CNAP (Calling Name Presentation, calling name shows) business is a kind of IN service of wireless intelligent network.This business is that the user is when this business of application, can submit the table of comparisons of a number and caller information to business department to, after this number and corresponding caller information input mobile communication system, when if the described user of certain customer call is arranged, then when the call through ring, will show speaker's caller information on called subscriber's mobile phone or the terminal.
The CNAP business provides in narrow band service, and a plurality of difference in functionalitys are arranged.Existing techniques in realizing provides the method for calling of caller information to be: when the calling subscriber calls out the called subscriber, Originating Office triggers professional SCP (the Service Control Point of arriving of its CNAP according to the initial CAMEL-Subscription-Information of calling terminal, service control point), SCP confirms the signatory CNAP business of calling terminal, with USSD/SMS (Unstructured SupplementaryServices Data, unstructured supplementary data traffic/Short Messaging Service, short message service) mode sends to terminal called by called office with caller information, replay call is presented on the terminal called interface caller information then.
After calling terminal made a call, SCP judged the signatory CNAP business of calling terminal, and at this moment, no matter whether calling terminal is ready to send caller information, and SCP can send caller information to terminal called; In addition, SCP is that the mode by USSD/SMS sends caller information, USSD/SMS message can take mobile phone and signal resource when sending, may cause conversation to carry out, USSD/SMS message can only be carried text and picture simultaneously, and when the information of carrying is too many, can take more mobile phone and signal resource, make himself transmission speed slow down or possibly can't send success, also can influence normal conversation simultaneously.
