Embodiment Construction

[0023] The basic idea of ​​the present invention is: when the SCP notifies the SSP to connect the user, by adding a prefix code to the calling number, the SCP can identify the call-back service user when determining the user's call duration after the call ends, and through calling the calling user Both parties record the call conditions of both parties, so that when the SCP determines the call duration of the user after the call is over, it can reasonably adjust the call duration of the user who called first. The method for determining the calling duration of the call-back service of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] If user A sends a callback request to the SCP, requesting to talk to user B, figure 1 It is a flow chart of a method for determining the call duration of the call-back service of the present invention, as figure 1 As shown, the method for determining the...

Abstract

The invention discloses a method for determining a calling time in a call-back service, the method includes the following steps: users send a callback request to a service control point (SCP), then according to the callback request, the SCP informs a SSP to connect two users. When the two users are connected successfully, the SCP restores a calling record and then the two users begin to communicate. After the communication of the two users, the SCP judges whether one user is a calling user. If the user is the calling user, the SCP searches and reads the calling record related to the user and adjusts the calling time of the user according to the read calling record. Otherwise, the SCP determines that the calling time of the user is the actual calling time. In the method of determining the calling time in the callback service, by adding a prefix code to the calling number, the SCP is able to identify the callback request, and record the connection state of the two users when the two users are connected to begin a communication, and adjust the calling time of the calling user after the communication. Therefore, the invention is able to realize a accurate timing, and lay a foundation for a flexible accounting.

Description

technical field [0001] The invention relates to the field of call-back services, in particular to a method for determining the call duration of the call-back service. Background technique [0002] With the development of the economy, people go abroad for travel or business activities more and more frequently. Due to the involvement of different countries, the international roaming communication fee will gradually increase. Under this development trend, the callback service proposes a technology to reduce the user's international roaming fee The solution, the so-called "call back", is to take advantage of the market opportunities in the international long-distance call charges in various countries, and the users in the high-toll countries and regions will convey the call request to the low-toll area, and then charge according to the lower local rate. [0003] If user A sends a call-back request to the service control point (SCP) and requests to talk to user B, the processing ...
