Embodiment 1

[0051] In this embodiment, in the Forked ringing state multi-channel playback scenario, the ATCF anchors the multi-channel playback media resources, and the ATGW anchors the media resources in the appendix image 3 . attached image 3 In the Forked call scenario, two calls are played at the same time. For the situation of more (N-way) calls being played at the same time, it can be deduced that ATCF realizes the announcement by anchoring multiple (N-way) media resources.

[0052] image 3 For the SIP signaling process and media anchoring schematic diagram of the Forked call ringing state multi-channel playback scenario in this embodiment, send image 3 As shown, the implementation of this embodiment may include the following steps:

[0053] Step 301, the user terminal initiates a call through the PCSCF, and the PCSCF sends an invite message to the ATCF, wherein the media description information carried is sdp1;

[0054] Step 302, in the case of supporting the anchored media...

Embodiment 2

[0064] Figure 4 It is the signaling flow chart of this embodiment, such as Figure 4 As shown, in the present embodiment, realizing multi-channel playback under the ringing state mainly includes the following steps:

[0065] In step 401, the calling user initiates a call request, and the PCSCF sends an invite to the ATCF, carrying media information sdp1.

[0066] In steps 402-403, the ATCF applies for the ATGW media resource for the calling media, and the ATGW returns the media resource RTP1, and the corresponding local sdp media is sdp2.

[0067] In steps 404-405, ATCF applies for ATGW media resource for the called media, ATGW returns media resource RTP2, and the corresponding local sdp media is sdp3.

[0068] Step 406, the ATCF forwards the call request to the SCSCF, carrying the media information sdp3.

[0069] Step 407, ATCF receives the first 18x ​​response message (to-tag1), carrying media information sdp4.

[0070] In steps 408-409, the ATCF updates the remote medi...

Embodiment 3

[0086] Figure 5 It is the signaling flow chart of this embodiment, such as Figure 5 As shown, in the present embodiment, realizing multi-channel playback under the ringing state mainly includes the following steps:

[0087] Steps 501-517 are the same as steps 401-417.

[0088] In steps 518-519, ATCF applies for ATGW media resource for the calling media of the second call (to-tag2), ATGW returns media resource RTP3, and the corresponding local sdp media is sdp6.

[0089] In steps 520-521, ATCF applies for ATGW media resources for the called media of the second call (to-tag2), and ATGW returns media resources RTP4, and the corresponding local sdp media is sdp7.

[0090] Step 522, ATCF forwards the 18x (to-tag2) response, carrying media information sdp6.

[0091] Steps 523-526, the 18x (tag2) message is confirmed by Prack. Different from the second embodiment, the ATCF transparently transmits the Prack and its response instead of replying the Prack response.

Abstract

The invention discloses a call playback method and device in a ringing state. Wherein, the method includes: after the ATCF forwards the call request initiated by the user terminal, when receiving the first temporary response message returned by the called side, apply for media resources for the first channel of playback media, and apply for media resources for the first channel of playback media Playing, wherein, the first provisional response message carries the description information of the first playback media; when ATCF receives the nth provisional response message of the call request, re-apply for a pair of media resources to anchor the nth channel Playback media, wherein, the nth provisional response message carries the description information of the nth playback media, and n is a natural number greater than or equal to 2; ATCF plays the nth playback media through the applied media resources.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a call playback method and device in a ringing state. Background technique [0002] IP Multimedia System (IP Multimedia Subsystem, IMS) is a brand-new form of multimedia services, which can meet the demands of newer and more diverse multimedia services of current terminal customers. figure 1 It is a schematic diagram of the networking structure of the IMS system in the related art. The following are respectively figure 1 Each functional entity in is described. [0003] The call session control function entity (Call Session Control Function, CSCF) is the core functional entity of the IMS system, and is mainly responsible for processing the signaling control during the multimedia call session. It manages user authentication of the IMS network, QoS of the IMS bearer plane, and cooperates with other network entities to control Session Initiation Protocol (SIP) sessio...
