A tau cycle configuration method and device

Abstract

The invention provides a TAU period configuration method and device and relates to the communication field, and via the method and device, a user terminal can be woken up timely and operations of other application platforms on the user terminal are not delayed on the premise that power is saved fully. The method comprises that all services that can be used by the user terminals in service of a base station are classified according to different packet-sending intervals; the user terminals are graded according to obtained residual electricity quantities of the terminals; and a TAU period is calculated according to a preset formula as well as the maximum of the packet sending interval of all the user terminals in service of the base station, the number of user terminals corresponding to eachtype of service, and the number of user terminals in each grade.

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); specifically, the UE When using NB-Iot, power saving technologies such as eDRX (enhanced Discontinuous Transmission, enhanced discontinuous transmission) and PSM (Power Saving Mode, power saving mode) are mainly used to reduce the energy consumption of user terminals and extend the standby time of user terminals. 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 ...

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 power; after the user terminal enters the PSM, only when the user terminal needs to send MO (mobile original) data, or the TAU (Tracking Area Update, tracking area update) cycle time is up, it needs to update the TA (Tracking Area, tracking area ) will exit the PSM mode; when the user terminal is in PSM and the TAU cycle time is not up and does not need to update the TA, even if the user terminal moves and causes the TA to change, it will not exit the PSM mode; EPC passes through after configuring the TAU cycle When the base station delivers to all terminals served by the base station, it does not distinguish the service type of the terminal (for example, service characteristics, frequency of sending packets, etc.), all user terminals are in the PSM state, and when the TAU period ends and the TA needs to be updated or the user terminal It is only woken up when the business is actively carried out. This will make it impossible for some application platforms to operate certain user terminals (such as setting hardware parameters, upgrading equipment software, etc.) at a certain moment. It can only be done when waking up and exiting PSM, which makes the application platform unable to operate the user terminal in time
