AI Technical Summary

Problems solved by technology

[0005] Using the existing frequency point configuration technology, there is a problem of poor accuracy, especially in high-traffic areas, and it is necessary to check the accuracy of the frequency point configuration in stages; the wireless network situation is relatively complicated, even through simulation planning, test data, etc. As a basis for planning to drop the frequency point, as the optimization proceeds, such as the adjustment of azimuth, downtilt, and power, the coverage will change; the field engineer needs to add as many frequency points as possible to reduce the probability of missing configuration, but this will lead to Increased workload and increased fallback delay

Abstract

The invention discloses a fallback frequency point configuration method, which comprises the steps: according to obtained user signaling, each fallback global system for mobile communication (GSM) cell which is corresponding to a call origination long term evolution (LTE) cell is determined; and the broadcast control channel (BCCH) of each fallback GSM cell is configured as a frequency point of a fallback frequency point group of the LTE cell. The invention also discloses a fallback frequency point configuration apparatus.

Description

technical field [0001] The present invention relates to a voice communication technology in mobile communication, and in particular, to a method and a device for the configuration of fallback frequency points. Background technique [0002] The Circuit Switched Fallback (CSFB) mechanism defined by the 3rd Generation Partnership Project (3GPP) ensures that the user is registered in the Evolved Packet System (EPS, Evolved Packet System) and the traditional circuit domain network at the same time. In the case of voice service, the EPS instructs the user to fall back to the circuit area network and then initiate a voice call. To implement CSFB services, two key technologies, fallback and return, need to be solved. The two parameters that are mainly concerned are fallback delay, also called connection delay, and return delay, also called unreachable time. [0003] The main processes of CSFB include: 1. Network selection and residency at startup: preferentially reside on the Long ...
