Embodiment Construction

[0047] The embodiment of the present invention provides a method for processing the call hold tone. The TAS judges whether it is necessary to provide the call hold tone to the opposite end user according to the content of the received hold service request message, thereby avoiding that the CS network and the IMS network repeatedly send the call hold tone to the opposite end user. Provide call hold tone, saving network resources.

[0048] Such as Figure 4 As shown, it is a flow chart of the processing method of the call hold tone in the embodiment of the present invention, which specifically includes the following steps:

[0049] In step S401, the TAS receives the hold service request message sent by the CS access IMS network control entity. Optionally, before the hold service request message is sent to the TAS, the CS accesses the IMS network control entity, such as the ICCF entity or the VCC AS, to determine whether the CS network has provided the call hold tone for the pee...

Abstract

The embodiment of the invention discloses a method for processing call holding voice, which comprises the following steps: receiving a call hold service request message sent by a circuit switching CS network, and confirming and executing whether the call holding voice is provided for corresponding end users or not according to contents of the hold service request message. A telephone application server TAS confirms the processing mode of the call holding voice according to the contents of the received hold service request message through the method, thereby preventing a CS network and an IMS network from providing the call holding voice repeatedly for the corresponding end users, network resources are saved, and the user experience level is also improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, system and device for processing call hold tone. Background technique [0002] The VCC (Voice Call Continuity, voice call continuity) technology provides the ability to transfer voice between a CS (Circuit Switched, circuit switched) domain and an IMS (IP Multimedia Sub-system, IP Multimedia Subsystem) domain. The core of VCC is VCC AS (Application Server, application server), called voice call continuity application server, which completes the switching function between circuit domain call branch and IP-CANVoIP (Voice over Internet Protocol, IP voice call) call branch. [0003] All user calls or sessions must pass through the VCC AS in the IMS domain to prepare for subsequent domain switching control. Calls initiated by VCC users from the CS and voice sessions initiated from the IMS domain must be routed to the VCCAS and then sent to the called party; si...
