A TAU cycle configuration method and apparatus

Abstract

The embodiment of the invention provides a TAU cycle configuration method and a TAU cycle configuration device, which relate to the communication field, and can enable the user terminal to be woken upin time without delaying the operation of other application platforms on the user terminal on the premise of sufficient power saving. The method firstly classifies all the services which can be usedby the user terminal of the base station service according to the packet sending time interval according to the packet sending time interval, and then grading all the user terminals of the base station service according to the remaining power of each user terminal of the obtained base station service, that is, grading the user terminals of the base station service according to the amount of remaining power, finally, according to the maximum value of the sending time interval of all user terminals served by the base station, the number of user terminals corresponding to each type of service, the number of user terminals of each level and the number of user terminals within the coverage range of each level of the base station, the TAU period is calculated according to the preset formula.

Description

technical field [0001] The present invention relates to the communication field, in particular to a TAU cycle configuration method and device. Background technique [0002] In order to further reduce the energy consumption of the terminal, technicians in the communication field invented NB-Iot (Narrow Band Internet of Things, narrowband Internet of Things), an Internet of Things method that can reduce the energy consumption of the user terminal UE (User Equipment); NB-Iot 3GPP stipulates that NB-Iot has a 20dB improvement in coverage compared to GPRS (General Packet Radio Service, General Packet Radio Service), and the base station will divide its coverage into three levels (0, 1, 2), MCL (Maxim coupling loss, maximum coupling loss) is 144, 154, 164 respectively, the higher the level of coverage (0 is higher than 1, 1 is higher than 2), the better the signal provided by the base station. [0003] Specifically, when the UE uses NB-Iot, it mainly uses power saving technologie...

Problems solved by technology

As far as the PSM mechanism is concerned, after the user terminal enters the state of no data service and voice service for a certain period of time, the MME (Moblity Management Entity, mobile management entity) in the EPC (Evolved Packet Core, evolved packet core network) in the NB-Iot architecture The node function) unit will determine that the user terminal enters the PSM, reject the base station to perform downlink services on the user terminal and the call request of the user terminal, and at the same time, the user terminal will turn off its own access stratum (Access Stratum, AS) function after entering the PSM (such as cell Select, etc.) to save points; after the user terminal enters PSM, it will exit PSM mode only when the user terminal needs to send MO (mobile original) data, or when the TAU cycle time is up and TA needs to be updated; when the user terminal is in PSM And when the TAU period is not up and there is no need to update the TA, even if the user terminal moves and causes the TA (Tracking Area Update, tracking area) to change, it will not exit the PSM mode; after the EPC is configured with the TAU period, it will be sent to the base station through the base station. For all terminals, the service type of the terminal (such as service characteristics, frequency of sending packets, etc.) and the communication status of the terminal (such as the coverage level of the location) will not be distinguished. All user terminals in the PSM state will wait until the TAU period ends. It will be woken up only when the TA needs to be updated or when the user terminal actively performs business, which will make it impossible for some application platforms to perform operations on certain user terminals (such as setting hardware parameters, upgrading equipment software, etc.) at a certain moment. It can only be performed when the user terminal is awakened and exits the PSM, which causes the application platform to be unable to operate the user terminal in time
