Embodiment Construction

[0033] The method for implementing a 3G video service when a terminal resides on a 2G network provided in an embodiment of the present invention is applied to such as figure 1 The system shown includes UE (User Equipment, user terminal), MSC / VLR (Visitor Location Register, visitor location register), HLR (Home Location Register, home location register) and CSP (Characteristic Service Platform, characteristic service platform ), adding a CSP in the mobile communication system, the CSP is a newly added network device in the existing network system in the embodiment of the present invention.

[0034] based on figure 1 In the system shown, the process of terminal camping on 2G to implement 3G video services may include: UE camping on the 2G network after booting up, sending a message to the CSP requesting to subscribe to the CSP service after the location update is successful, the CSP modifies the user subscription data in the HLR, and updates User's subscription information in H...

Abstract

The embodiment of the invention provides a method, a system and equipment for realizing third-generation (3G) video service through terminal staying second-generation (2G). A control switch point (CSP) is added in a mobile communication system, a calling terminal firstly initiates the reselection from a 2G network to a 3G network and then initiates the video service, a called side home location register (HLR) receives the router information inquiry requests sent by a calling side mobile switching center (MSC), when a CSP service signed by a called terminal is inquired, the called side HLR sends router information pointing to the CSP to the calling side MSC, the calling side MSC initiates initial address message towards a CSP platform according to the router information, the CSP informs the called terminal to reselect the 3G network from the 2G network, the 3G video service connection from the calling terminal to the called terminal is built, the updating reformation on a GSM network is not needed, in addition, the continuing time delay increase on the 3G video service is little, and the user experience of the voice service is ensured when that users can normally use the 3G video type service is ensured.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method, system and equipment for realizing 3G video services when a terminal resides in 2G. Background technique [0002] In the early stage of 3G (3rd-generation, third-generation mobile communication technology) construction, the network coverage is not perfect, there are many 2G / 3G boundaries, 2G / 3G interoperability problems are prominent, user experience is poor, call drops, voice quality is poor, and calls are difficult to receive Pass. The 2G network is mature, with high voice quality and good user experience. 2G voice services and 3G videophone and high-speed data services have their own advantages. Combining the advantages of the two networks will help improve user experience and rapidly develop 3G services. Currently, there are three technical solutions: [0003] A. Dual network dual standby solution [0004] There are no special requirements for the network. Th...
