Embodiment Construction

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with specific embodiments. It should be understood that the invention is not limited to the specific examples.

[0031] figure 1 It is a schematic diagram of a mobile network, which includes multiple mobile terminals (MS) 1 (for brevity, only one MS is shown here), a base station system (BSS) 2, a mobile switching center (MSC) 3 and a GPRS support Node (SGSN)4. A multimedia group call service is started by MS 3, and BSS 2 is connected with MSC 3 or with SGSN 4 according to whether the multimedia group call service is a voice group call service or a data group call service, so that the voice group call service is established by circuit switching, and data group call services are established by packet switching.

[0032] According to the level of radio resource usage efficiency, the present invention has the following two different specific implementat...

Abstract

The invention provides a method and device for multimedia group calling business in the mobile network. The voice group calling is established by the circuit exchange and the data combination can be established by the branch exchange.

Description

technical field [0001] The present invention relates to mobile communication technology, more specifically, to a method and device for performing multimedia group call service in a mobile network. Background technique [0002] Multimedia Group Call Service (MGCS) is a service where a talker can speak and send data (such as photos, pictures) to other listeners in the same group. The 3GPP standard has defined the Voice Group Call Service (VGCS), but this is only limited to the voice service, while the MGCS extends the voice service to multimedia (voice, data) services. [0003] If the implementation of MGCS considers the efficiency of radio resources, 3GPP needs to further define new signaling or add a provision field to the current signaling. [0004] If the implementation of MGCS does not need to consider the efficiency of radio resources, the current 3GPP standard does not need to be changed, and the voice quality and spectrum efficiency are better than the current push-to...
