Problems solved by technology

[0014] 3. If the user only signs a contract and activates the CW service, he can only perform the CW service, and cannot perform call transfer and three-way calling
[0015] To sum up, there will also be two call branches when conducting CW services, but no matter what kind of subscription method, once the master user triggers the CW service, the call can only be selected between the two users, and the user cannot call according to the call needs. Flexible call forwarding or three-way calling, which is obviously not what users want

Embodiment Construction

[0038] ◆Implementation scheme based on home location register (HLR, Home Location Register)

[0039] 1. Realization of CW to 3WC

[0040] refer to Figure 4 . The operation code that can be configured on the HLR to convert CW to 3WC is: *FC (where FC is a feature code uniformly defined by MSC and HLR). This operation code can be flexibly configured, assuming it is: *90. The MSC is set so that the MSC analyzes the number dialed by the master user after the CW service is triggered. After triggering the CW service, the main control user dialed "*90+ If the MSC receives the number and analyzes the number, it will find that the user dialed a series of Feature service operation codes (feature service operation codes, in this manual, refers to the operation codes that the MSC determines needs to trigger the FEATURE service), then Need to trigger supplementary services to HLR. After HLR receives MSC's FEATREQ message, it judges that the operation code carried in the message is the...

Abstract

This invention provides a method for realizing strengthened CW services, in this way, users can transmit operation codes to carry out three-party session or call transfer directly when triggering the CW service and do not exit from the CW service first.

Description

field of invention [0001] The present invention relates to the implementation of enhanced CW services. Background technique [0002] Call Waiting (CW, Call Waiting) service refers to allowing the main control user (the user who has signed up and activated the CW service) to hear the CW prompt tone notification when receiving a third-party call during a two-party call. At this time, the master user can choose to answer or ignore the call from the third party. If the master user answers the call, the master user can click the key to switch calls back and forth between two calls. See flow chart figure 1 . [0003] User A subscribes and activates the CW service, and user A and user B are talking on the phone. At this time, the status of the master user A is 2-way; the third-party user C calls user A, and the Mobile Switching Center (MSC, MobileSwitching Center) will pass the next call. Send a Flash With Information message to user A to send a CW notification. At this time,...
