Embodiment Construction

[0075] The basic idea of ​​the present invention is: set the identity verification mechanism to the calling user in the application server of the called side, verify the user identity carried in the call request of the call back initiated by the calling user, and the calling user who passes the identity verification Only when the incoming call is allowed, otherwise, the calling user will be denied the incoming call. The invention fully guarantees the call access sequence of the calling user to the called user, embodies the fairness of call access, and eliminates the preferential call access right of malicious users.

[0076] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

Abstract

This invention discloses an assess method for a completion of call to a busy subscriber service based on identity identification, comprising the following step of: verifying the identity of a calling subscriber in a call request, after a called side application server receives a call request carrying an indication of call completion; if the verification is passed, allowing the calling subscriber to access; otherwise refusing the calling subscriber from accessing. The invention synchronously discloses an access system for a completion of call to a busy subscriber service based on identity identification, including: a receiving unit, a verifying unit, an access unit and a refusing unit, wherein the receiving unit is used for receiving the call request carrying the indication of call completion; the verifying unit is used for verifying the identity of the calling subscriber in the calling request, triggering the access unit if the verification is passed, otherwise triggering the refusing unit; the access unit is used for accessing the call for the calling subscriber; and the refusing unit is used for refusing the calling subscriber from accessing the call. The invention further discloses a call access apparatus. The invention sufficiently ensures the order of access to the called subscriber for the calling subscribers, reflects the impartiality of the call access, and eliminates the priority call access right of a malicious subscriber.

Description

technical field [0001] The present invention relates to a busy call back service (CCBS, Completion of Call to Busy Subscriber) processing technology, in particular to a called side application server (AS, Application Server) in the busy call back service based on identification of the busy call back service Access method and system. Background technique [0002] figure 1 It is a flow chart of the existing busy call back service, such as figure 1 As shown, the existing busy call back business process includes the following steps: [0003] In step 1, the calling user A calls the called user B, and the called user B rejects the call request of the calling user A because the line is busy. [0004] In step 2, the calling side application server O_AS sends a subscription message (SUBSCRIBE) to the called side application server T_AS, subscribing to the idle state of the called user. [0005] Step 3: After receiving the SUBSCRIBE sent by O_AS, T_AS returns a 202 OK message to c...
