Problems solved by technology

[0006] The point-to-multipoint broadcast or multicast technology is not introduced into the multi-party communication system, and the point-to-point multi-party communication is effective for a small to medium number of users, but when the number of users increases in large quantities, it will be Consuming a large amount of bandwidth capacity, the server system will be difficult to support, it is easy to cause bottlenecks, and the efficiency is low

Embodiment 1

[0033] In this embodiment, the session control server judges whether the preset broadcast or multicast bearer establishment conditions are met, and if so, establishes the broadcast or multicast bearer, see figure 1 , an embodiment of the present invention provides a method for establishing a broadcast or multicast bearer, which specifically includes:

[0034] Step 101: The session control server presets the conditions for establishing a broadcast or multicast bearer for multi-party communication.

[0035] Among them, there are many kinds of establishment conditions, including but not limited to the following: the number of user terminals participating in the session reaches a preset value; or user terminals with specified attributes join the session; or the number of user terminals participating in the session reaches a preset value The user terminal with the set value and the specified attribute joins the session.

[0036] Step 102: When establishing a multi-party communicat...

Embodiment 2

[0048] In this embodiment, the user terminal is a PoC user terminal, and the multiparty communication session is a group session. In addition, the session control server determines whether the preset broadcast or multicast bearer establishment conditions are met and establishes the broadcast or multicast bearer. The group session in this embodiment can be established within the same network or across networks. see Figure 4 , an embodiment of the present invention provides a method for establishing a broadcast or multicast bearer, which specifically includes:

[0049] Step 201: The PoC session control server (also referred to as PoC server performing controlling function) presets the conditions for establishing broadcast or multicast bearer of a multi-party communication group session.

[0050] There are various conditions for establishing preset broadcast or multicast bearers, including but not limited to at least one of the following:

[0051] 1) The number of participants...

Embodiment 3

[0064] In this embodiment, the user terminal is a PoC user terminal, and the multiparty communication session is a group session. In addition, the session control server judges whether the preset broadcast or multicast bearer establishment conditions are met, and the PoC server participates in the function establishment of the broadcast or multicast bearer. The group session in this embodiment can be established within the same network or across networks. see Figure 6 , an embodiment of the present invention provides a method for establishing a broadcast or multicast bearer, which specifically includes:

[0065] Step 301: The PoC session control server presets the establishment condition of the broadcast or multicast bearer of the multi-party communication group session.

[0066] The above establishment conditions are the same as those described in Embodiment 2, and will not be repeated here.

[0067] Step 302: When establishing a multi-party communication PoC group sessio...

Abstract

The invention discloses a method for establishing a broadcast or multicast bearer, an apparatus and a system thereof, and belongs to the communication technical field. The method comprises the following steps: judging whether preset conditions of establishing the broadcast or multicast bearer are satisfied when multi-party communication session is established or during the multi-party communication session; and if the conditions are satisfied, the broadcast or multicast bearer is established with a user terminal with a broadcast or multicast support function. The apparatus comprises a judgment module and an establishment module. The system comprises a participation function device and a control function device. As the broadcast or multicast is established after the conditions of establishing the broadcast or multicast bearer are judged to be satisfied, a point-to-multi-point broadcast or multicast technology is introduced to a multi-party communication system, which improves the multi-party communication efficiency and greatly saves the bandwidth capacity, and reduces the burden of a server system and avoids the bottleneck particularly when the number of users significantly increases.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method, device and system for establishing a broadcast or multicast bearer. Background technique [0002] MBMS (Multimedia Broadcast Multicast Service) proposed by 3GPP (3rd Generation Partnership Project) and BCMCS proposed by 3GPP2 (3rd Generation Partnership Project 2) (Broadcast and MulticastServices, broadcast and multicast services) have been widely used. MBMS can efficiently play a variety of rich and exciting multimedia content through the existing UMTS (Universal Mobile Telecommunication System) network, not only allowing mobile users to receive news, weather and traffic forecasts, stock price information, MP3 music, etc. , TV programs and streaming media services, but also enables network operators to benefit greatly from cost-effective MBMS services. [0003] The mobile multimedia broadcast service mainly refers to the multimedia service based on ...
