Description

Cell access method and device

Technical Field

The present application belongs to the field of communications, and in particular, to a cell access method and apparatus.

Background

Currently, when fifth Generation Mobile Communication technology (5G) network deployment is incomplete, or 5G signal environment is poor, a terminal still needs to perform voice traffic or video traffic on the fourth Generation Mobile Communication technology (4G) network.

In a 5G network, a network side device configures a measurement event to a terminal, so that the terminal can measure signal conditions of a current serving cell, a co-frequency cell, and a inter-frequency cell. After the terminal reports the B1 (the signal quality of the inter-frequency cell is stronger than the preset threshold) measurement report of the inter-frequency cell, the network side device will drop the terminal back to the 4G network for voice service or video service in a redirection manner.

However, when the terminal is in the edge coverage area of the 5G cell, the terminal may continue to perform cell measurement and report because the 5G signal is weak at this time. Therefore, when the network side equipment issues the redirection command, the terminal scans the frequency point cell indicated by the redirection command according to the redirection command, and therefore, if the redirection frequency point is an abnormal redirection frequency point, the terminal may still access the cell indicated by the abnormal redirection frequency point, and therefore, the terminal still accesses the frequency point cell with poor signal, or cannot search the indicated frequency point cell (empty frequency point), and still stays in the current service cell. Therefore, the quality of the terminal voice service or video service is poor, and the user experience is poor.

As further development and evolution of the 4G Voice over LTE (Voice over LTE) technology, arrival of a New Voice over New Radio (VoNR) technology can provide better service experience for users. Operators in various countries begin to continuously announce the commercial process of 5G VoNR, which also means that VoNR is going to be formally started and 5G new call era is going to be formally started. The core of the 5G new call is an audio and video service integrated solution created for users based on the VoNR technology. The voice service, the video service and the data service are all carried on a 5G network, and the characteristics of large bandwidth and ultra-low time delay of the 5G network are utilized, so that better conversation experience is brought to users. In the VoNR call process, the terminal does not need to fall back to the 4G for service, and compared with voice or video call provided by general software, the VoNR service is carried by special transmission, and can be scheduled preferentially when network resources are in shortage, so that the speed is more stable, the blocking is not easy, and the call quality is more guaranteed. However, the existing 5G network deployment is still not perfect, and in some areas where the 5G network deployment is imperfect, a 4G network is still needed for supplement, so as to ensure the continuity of voice call and video call of users; the terminal still needs to fall back to 4G for voice or video service in the weak 5G signal environment.

In the embodiment of the application, after the terminal acquires the first frequency point, the first frequency point is compared with at least one second frequency point, and if the first frequency point is the same as any one of the at least one second frequency point, the first frequency point is determined as a target frequency point.

Optionally, in this embodiment of the application, a redirection command sent by a network side device is received during a VoNR call performed by a terminal, a first frequency point is obtained according to the redirection command, then the terminal may compare the first frequency point with at least one second frequency point, and if the first frequency point is the same as any one of the at least one second frequency point, that is, the first frequency point is a frequency point measured and reported between terminals, the terminal directly determines the first frequency point as a target frequency point, so that the terminal can directly search a network and access the first frequency point.

After receiving a redirection command sent by a network side device, a terminal is not directly accessed to a cell indicated by the redirection command, but after receiving the redirection command, a target frequency point required to be accessed is determined according to the cell indicated by the redirection command and a cell indicated by a measurement frequency point reported by the terminal historically, and then the cell indicated by the target frequency point is accessed.

In the embodiment of the application, if the terminal does not search the cell indicated by the target frequency point, the terminal prohibits accessing the target frequency point within the second preset time, and/or reduces the access priority of the current serving cell.

Optionally, in this embodiment of the application, if the terminal does not search for the cell indicated by the target frequency point, that is, the terminal fails to search for the network at the target frequency point, and finds no available cell, the target frequency point is determined as an abnormal frequency point or an empty frequency point, and then the terminal may prohibit access to the target frequency point within a second preset time, and/or reduce the access priority of the current serving cell.
