Method and apparatus for setting tracking area

Abstract

The embodiment of the invention, which relates to the technical field of communication, discloses a method and apparatus for setting a tracking area. With the method and apparatus, continuous delay of a terminal during a voice service execution process can be reduced. The method comprises: the numbers of times of fallback of services executed by all terminals into all location areas in a coverage area of a first system network as well as a total number of times of service fallback request initiating by all terminals within designated time are determined respectively; according to the numbers of times of services falling back to all location areas as well as the total number of times of the service fallback requests, fallback proportions of all location areas are determined; the location area corresponding to the largest fallback proportion among the fallback proportions is determined as a target location area corresponding to the coverage area of the first system network; and when the target location area is different from a preset location area, a tracking area corresponding to the target location area is set as a tracking area corresponding to the coverage area of the first system network. The method and apparatus are suitable for a setting process of a tracking area.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for setting a tracking area. Background technique [0002] In the early stage of 4G (English: The 4th Generation mobile communication, Chinese: 4th generation mobile communication technology) network development, in order to provide better voice services for 4G users, when performing voice services on 4G terminals (terminals for short), it is necessary to The voice service falls back to the CS (English: Circuit Switched, Chinese: circuit switching) domain. Here, a 3G network is taken as an example for description. In an actual 4G network, errors in data configuration, changes in the network environment, or changes in service models will make the preset TAC unable to adapt to the current application scenario. As a result, during the voice fallback process, the LAC (English: Location area code, Chinese: Location Area Code) corresponding to the TAC (Eng...

Problems solved by technology

[0004] However, since the distribution of terminals in the coverage area of ​​4G base stations is not uniform, and the frequency of CSFB voice services for each terminal is also uncertain, after adopting the above technical solution to set the tracking area of ​​the 4G network, it is often due to The pre-set TAC is unreasonable, so that the terminal in the coverage area of ​​the 4G base station needs to initiate the location update process when performing the CSFB voice service, which increases the probability of the terminal initiating the location update process, thereby increasing the terminal's time during the voice service process. connection delay
