Problems solved by technology

However, there is still no way to solve the problem of enabling the AMR voice service to be smoothly switched from the WCDMA system network to the GSM system network during the communication process in the WCDMA system. Therefore, how to realize the inter-system retry method of AMR and other voice services is of great significance. and urgent problems to be solved
[0012] In practical application, the above solution has the following problems: in the existing 2G and 3G hybrid network, when the resources of the current network for voice services such as AMR are insufficient, other network resources cannot be better utilized, resulting in a decrease in communication service quality
[0013] The main reason for this situation is that the current 2G and 3G hybrid networking technology does not solve the problem of how to switch from the WCDMA system network to the GSM system network in the communication process of voice services such as AMR

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] Generally speaking, the principle of the present invention is to obtain the adjacent GSM 2G cell information of all WCDMA 3G cells according to the network planning information. The process first obtains the active set composed of all WCDMA cells that provide services to the UE, and then obtains the WCDMA cells whose signal quality meets the requirements among the neighboring WCDMA cells of this cell, and finally according to the network planning information, the public neighboring GSM cells of the above two types of cells Perform priority sorting, and migrate AMR voice services to GSM cells according to priority. The invention migrates the AMR voice service to the GSM neighboring cells within the coverage range through different priorities, thereby greatly...

Abstract

This invention relates to a concomitant phone service solving plan for the second and the third generations of mobile communication system and discloses a switch method among systems of mobile communication service, thus, when a 3G system of WCDMA meets with the situation of shortage of network resources in communication, it transfers the AMR phone service to a 2G of GSM system network smoothly so as to fully utilize the two kinds of systematic resources and increase the network performance of the AMR phonetic service. This invention fully utilizes the network design information and quality test information of the RACH channel to get the GSM adjacent area covering the UE based on the position relation of the areas.

Description

technical field [0001] The invention relates to a voice service solution for the coexistence of second-generation and third-generation mobile communication systems, in particular to a direct retry method between systems of mobile communication services. Background technique [0002] Mobile communication technology has developed rapidly since it entered the second generation of mobile communication (The Second Generation, referred to as "2G") at the end of the 20th century. Among them, the Global System of Mobile communication (Global System of Mobile communication, referred to as "GSM") has Currently, it has become the largest mobile business network with global coverage. [0003] However, with the increase in the number of users and the continuous improvement of the requirements for business types and performance, 2G gradually shows limitations in data transmission capabilities. Therefore, the third generation of mobile communication (The Third Generation, referred to as "...
