Abstract

A video media playing method includes: A media server receives a call request message from originating UE, where the call request message includes first session description protocol (SDP) information of the originating UE; the media server receives a first response message returned by terminating user equipment (UE); the media server determines, based on the first response message, that the terminating UE does not support a resource reservation mechanism/procedure; the media server sends a second response message to the originating UE, where the second response message includes second SDP information used to respond to the first SDP information; and the media server performs video media negotiation with the originating UE through the resource reservation mechanism/procedure.

First claim

What is claimed is:

1. A video media playing method, comprising:
receiving, by a media server, a call request message from an originating user equipment (UE), wherein the call request message indicates a terminating UE and comprises first session description protocol (SDP) information of the originating UE;
receiving, by the media server, a first response message returned by the terminating UE; and

determining, by the media server based on the first response message, that the terminating UE does not support a resource reservation procedure;
in response to the determining that the terminating UE does not support the resource reservation procedure, sending, by the media server, a second response message to the originating UE, wherein the second response message comprises second SDP information, and the second SDP information is used to respond to the first SDP information; and
performing, by the media server, video media negotiation with the originating UE through the resource reservation procedure.

2. The method according to claim 1 , wherein the performing, by the media server, video media negotiation with the originating UE through the resource reservation procedure comprises:
sending, by the media server, a first update message to the originating UE, wherein the first update message comprises third SDP information of video media; and
receiving, by the media server, a third response message sent by the originating UE, wherein the third response message comprises a result of video media negotiation between the originating UE and the media server.

3. The method according to claim 2 , wherein the third SDP information of the video media comprises audio description information of the video media and video description information of the video media.

4. The method according to claim 2 , wherein:
a header field of the first update message comprises indication information indicating the originating UE to perform video media negotiation through the resource reservation procedure, or
wherein the third SDP information of the video media comprises a quality of service (QOS) parameter of the video media.

5. The method according to claim 2 , wherein
the third response message indicates that the originating UE has completed resource reservation.

6. The method according to claim 2 , wherein after the receiving, by the media server, a third response message sent by the originating UE, the method further comprises:
receiving, by the media server, a second update message sent by the originating UE, wherein the second update message indicates that the originating UE has completed resource reservation.

7. The method according to claim 6 , wherein after the receiving, by the media server, a second update message sent by the originating UE, the method further comprises:
sending, by the media server, a fourth response message to the originating UE, wherein the fourth response message indicates that the media server has completed resource reservation.

8. The method according to claim 2 , wherein before the sending, by the media server, a first update message to the originating UE, the method further comprises performing, by the media server, resource reservation for the video media; and the first update message indicates that the media server has completed resource reservation.

9. The method according to claim 7 , wherein after the receiving, by the media server, a second update message sent by the originating UE, the method further comprises:
sending, by the media server, media stream data of the video media to the originating UE.

10. The method according to claim 1 , wherein the first response message is a 180 message, and the determining, by the media server based on the first response message, that the terminating UE does not support the resource reservation procedure is performed based on determining that no 183 message is received from the terminating UE by the media server.

11. The method according to claim 1 , wherein the second response message indicates that the terminating UE does not support the resource reservation procedure.

12. A media server, comprising a transceiver unit and a processing unit, wherein
the transceiver unit is configured to receive a call request message from an originating user equipment (UE), wherein the call request message indicates a terminating UE and comprises first session description protocol (SDP) information of the originating UE;
the transceiver unit is further configured to receive a first response message returned by the terminating UE;
the processing unit is configured to determine, based on the first response message, that the terminating UE does not support a resource reservation procedure;
the transceiver unit is further configured to send, in response to the determining that the terminating UE does not support the resource reservation procedure, a second response message to the originating UE, wherein the second response message comprises second SDP information, and the second SDP information is used to respond to the first SDP information; and
the transceiver unit is further configured to perform video media negotiation with the originating UE through the resource reservation procedure.

13. The media server according to claim 12 , wherein the transceiver unit is specifically configured to:
send a first update message to the originating UE, wherein the first update message comprises third SDP information of video media; and
receive a third response message sent by the originating UE, wherein the third response message comprises a result of video media negotiation between the originating UE and the media server.

14. The media server according to claim 13 , wherein the third SDP information of the video media comprises audio description information of the video media and video description information of the video media.

15. The media server according to claim 13 , wherein a header field of the first update message comprises indication information indicating the originating UE to perform video media negotiation through the resource reservation procedure, or wherein the third SDP information of the video media comprises a quality of service (QOS) parameter of the video media.

16. The media server according to claim 13 , wherein
the third response message indicates that the originating UE has completed resource reservation.

17. The media server according to claim 13 , wherein
the transceiver unit is further configured to: after receiving the third response message sent by the originating UE, receive a second update message sent by the originating UE, wherein the second update message indicates that the originating UE has completed resource reservation.

18. A communications system, comprising a media server, wherein the media server is configured to:
receive a call request message from an originating user equipment (UE), wherein the call request message indicates a terminating UE and comprises first session description protocol (SDP) information of the originating UE;
receive a first response message returned by the terminating UE, and determine based on the first response message, that the terminating UE does not support a resource reservation procedure;
send, in response to the determining that the terminating UE does not support the resource reservation procedure, a second response message to the originating UE, wherein the second response message comprises second SDP information, and the second SDP information is used to respond to the first SDP information; and
perform video media negotiation
