Problems solved by technology

[0061] Therefore, using the current method for media negotiation, only a single network entity can perform media negotiation, that is, conduct a media negotiation to obtain a media negotiation result between a network entity and a network entity, and it is still not possible to implement one-to-many and multi-party media negotiation for one party

Embodiment 1

[0105] figure 2 It is a schematic diagram of a system for implementing media negotiation provided in the first embodiment of the present invention. The first embodiment of the present invention provides a system for realizing one-to-multi-party media negotiation, and the system includes: a server and a first network entity;

[0106] The server obtains at least two negotiated SDP message bodies, each negotiated SDP message body carries media information negotiated with the first network entity, and merges the obtained at least two negotiated SDP message bodies to obtain a merged SDP message body, And carry out media negotiation with the first network entity through the SDP message body of merging, obtain the SDP message body after negotiation, the SDP message body after this negotiation carries the media information after negotiating to the first network entity; And the first network entity then uses for media negotiation with the server.

[0107] see figure 2 , the presen...

Embodiment 2

[0118] image 3 It is a schematic diagram of a system for implementing media negotiation provided in the second embodiment of the present invention. What the second embodiment of the present invention provides is to realize one-to-many system, refer to image 3 , the system includes: a server and at least two network entities;

[0119] The server obtains a negotiated SDP message body, the negotiated SDP message body carries media information for negotiation between at least two network entities, the server decomposes the obtained SDP message body, obtains at least two decomposed SDP message bodies, and uses at least two A decomposed SDP message body performs media negotiation with at least two network entities to obtain at least two negotiated SDP message bodies, and each negotiated SDP message body carries a negotiation for one network entity in the at least two network entities The following media information; at least two network entities are used for media negotiation wi...

Embodiment 3

[0131] Figure 4 It is a schematic diagram of a method for implementing media negotiation provided in the third embodiment of the present invention. This embodiment takes the ring-back tone service as an example, because the server in this embodiment both negotiates as a multi-party and also negotiates as a party, so Figure 4 The ring back tone application server in comprises the server first unit in the first embodiment and the server second unit in the second embodiment, and concrete steps are described as follows:

[0132] Steps 401 to 413 are a process in which the server performs media negotiation with UE a as multiple parties.

[0133] Step 401: UE a sends an INVITE message to the RBT application server.

[0134] In this embodiment, UE a sends an INVITE message of the SIP protocol to the ring back tone application server as the calling party, so as to invite the called UE b to make a call request through the ring back tone application server, where the ring back tone ...

Abstract

This invention discloses a method for realizing media negotiation including: a server obtains at least two negotiated SDP message bodies, each of which carries a medium message negotiating on a same network entity, and the server combines said two SDP message bodies to negotiate with the same network entity to get a negotiated SDP message body, which carries the medium message about negotiation on the same network entity. This invention also discloses a method for realizing medium negotiations and a system and servers corresponding to the two methods.

Description

technical field [0001] The invention relates to the communication field, in particular to two systems, methods and servers for realizing media negotiation. Background technique [0002] Before establishing a media channel between network entities for media exchange, it is often necessary to conduct media negotiation between network entities in advance, that is, to negotiate the service quality and reserved resources required for media exchange according to their respective media capability information. For example, the Session Initiation Protocol (SIP, SessionInitiation Protocol) network is a network that uses SIP messages to initiate, manage, and terminate various types of multimedia services. The multimedia services include services such as IP telephony and video sessions. A network that applies SIP messages to create, modify and terminate multimedia sessions between one or more SIP entities. The entities in the SIP network, also known as SIP entities, carry the Session D...
