Problems solved by technology

However, the QoS (Quality of Service) of the existing GPRS system is difficult to guarantee, especially the voice part requires a small delay and no jitter. If the video call is directly carried on the existing GPRS system, the user experience will be poor

Embodiment Construction

[0016] In the existing solution, if the video call (including voice and video) is packaged together and transmitted on GPRS, since the QoS of GPRS is difficult to guarantee, no real application can be provided.

[0017] Therefore, in the embodiment of the present invention, voice and video are transmitted separately, specifically, voice is carried on a circuit domain (Circuit Switch, CS) network, and video is carried on a packet domain (Packet Switch, PS) network. The circuit domain network mentioned here is the network adopted by voice telephony which is more commonly used at present, and the packet domain network is the GPRS or CDMA data domain network, that is, the network used to carry IP services. The following uses GSM / GPRS as an example to introduce the embodiments of the present invention.

[0018] The method for implementing a video call provided by an embodiment of the present invention includes the following steps:

[0019] [1] The first user equipment and the seco...

Abstract

The invention discloses a method of realizing video calling and a device, comprising: a first user equipment transmits speech flow of the video calling to a second user equipment through a circuit field; the first user equipment transmits a video flow of the video calling to the second user equipment through a grouping field. The scheme which adopts the speech and the video respectively loaded on a circuit field network and a grouping network solves the problems of releasing deficient bandwidth. In addition, the invention realizes the video calling without changing or updating the base station equipment.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for realizing video calling. Background technique [0002] The existing mobile network is dominated by voice calls. With the development of technology, people put forward the demand for video calls. However, existing video calls have high bandwidth requirements and can only be carried on mobile networks with relatively high rates. The traditional GSM (Global System Mobile, Global System for Mobile Communications) circuit domain network is limited by bandwidth and cannot carry video calls well. If the GSM network is replaced with a WCDMA (Wideband Code Division Multiple Access) / TD-SCDMA (Time-Division Synchronization Code Division Multiple-Access) network, the investment is huge, so how Realizing video calling on the basis of GSM network has become a topic worthy of research. [0003] One solution is to upgrade the base station in the GSM system...
