Method and device for notifying call information

Abstract

The embodiment of the invention discloses a method and device for notifying call information. Through the invention, the problem that a terminal device can not know the voice call information or receive the call in real time in the process of transmitting data in a packet switched domain is solved, bad experiences of users can be reduced, and satisfaction on the voice service is improved. Meanwhile, network devices such as an MSC (mobile switching center), a SGSN (service GPRS (general packet radio service) support node), a BSC (base station controller) and the like of a core network do not need to be reconstructed, change of the terminal side is little, the operation cost is low, the implementation effect is good, and the compatibility with the existing call reminding service is good.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for notifying incoming call information. Background technique [0002] According to the existing communication processing mechanism, when GSM (Global System for Mobile Communications, Global System for Mobile Communications) / GPRS (General Packet Radio Service, General Packet Radio Service technology) B-type terminals continue to receive business data such as mobile phone video through the GPRS network , there will be a problem that the user cannot obtain the incoming call information. [0003] For example: when the user continues to receive packet domain data, if there is an incoming call, the called terminal will not send any prompts to the user, but the calling party user will receive the message "The user you are calling is temporarily unavailable" Prompt tone, similar to this, SMS cannot be received and processed on the...

Problems solved by technology

However, this solution has the following problems: difficulties in deployment and maintenance, incomplete procedures for dealing with related protocols on existing network terminals, immature Gs interface protocols, and many other problems

Moreover, the solution of "upgrading the core network to support the Gs interface" requires a large network transformation, and the investment cost is high, so it is difficult to be widely used

[0014] And "BSC, Base Station Controller (BSC) upgrade to support joint paging" also needs to upgrade the wireless equipment of the base station controller, and this equipment is deployed on a large scale, and the cost of upgrading and upgrading is high, and it is also difficult to be widely used.

[0015] Similar to the above principles, for other second-generation (2G) or second-and-a-half-generation (2.5G) mobile communication networks, such as CDMA networks, there are also technologies that do not support packet domain data transmission and circuit domain due to the use of IOS4.0 standards and other technologies. The concurrency problem of paging will also cause the problem that the user cannot answer the incoming call when the packet data call is activated
