Description

TAU period configuration method and device
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for TAU period configuration.
Background
In order to further reduce the energy consumption of the terminal, technicians in the communication field invented an NB-Iot (Narrow band internet of Things) internet of Things mode capable of reducing the energy consumption of the user terminal ue (user equipment); specifically, when the NB-Iot is used, the UE mainly uses Power Saving technologies such as eDRX (enhanced Discontinuous Transmission) and PSM (Power Saving Mode) to reduce the energy consumption of the UE and prolong the standby time of the UE. AS for the PSM mechanism, after the user terminal enters a state without data service and voice service for a certain time, a Mobility Management Entity (MME) unit in an EPC (Evolved Packet Core) in an NB-Iot architecture may determine that the user terminal enters the PSM, reject a base station to perform downlink service and a call request of the user terminal to the user terminal, and simultaneously close an Access Stratum (AS) function (e.g., cell selection, etc.) of the user terminal to save power after entering the PSM; after the user terminal enters the PSM, the PSM mode is exited only when the user terminal needs to send mo (mobile origin) data or the TAU (Tracking Area update) cycle time is up to the time TA (Tracking Area) needs to be updated; when the user terminal is in PSM and the TAU cycle time is not up to update the TA, the PSM mode can not be exited even if the TA is changed due to the movement of the user terminal; when the EPC is delivered to all terminals served by the base station through the base station after configuring the TAU period, the service types (for example, service characteristics, packet transmission frequency, etc.) of the terminals are not distinguished, and all the user terminals are wakened in the PSM state until the TA needs to be updated after the TAU period time is over or the user terminal actively performs a service, so that: if some application platforms need to operate some user terminals (such as setting parameters of hardware, upgrading device software, etc.) at a certain time, the operation cannot be performed, and the operation can be performed only when the user terminal is awakened to exit the PSM, so that the application platforms cannot operate the user terminal in time.

To more clearly illustrate the beneficial effects of the scheme provided by the above embodiment, taking the total number of the user terminals of the base station as 1000, the services are divided into 10 classes as shown in table 1, and the user terminals are divided into 10 classes as shown in table 2 as an example for explanation:
(1) ensuring the number ratio of the user terminals corresponding to different types of services to be unchanged: the first type of service accounts for 10%, the second type of service accounts for 15%, the third type of service accounts for 20%, the fourth type of service accounts for 20%, the fifth type of service accounts for 15%, the sixth type of service accounts for 5%, the seventh type of service accounts for 5%, the eighth type of service accounts for 5%, the ninth type of service accounts for 4%, and the tenth type of service (packet sending frequency is 30 hours/time) accounts for 1%; (all refer to the ratio of the number of the user terminals corresponding to the service to the total number of the user terminals)

When the first-rank ue accounts for 0%, the second-rank ue accounts for 5%, the third-rank ue accounts for 10%, the fourth-rank ue accounts for 15%, the fifth-rank ue accounts for 20%, the sixth-rank ue accounts for 15%, the seventh-rank ue accounts for 10%, the eighth-rank ue accounts for 10%, the ninth-rank ue accounts for 15%, and the tenth-rank ue accounts for 0%, the TAU period Time _ TAU is 30/((1% + 50+ 3% + 100+ 6% + 150+ 10% + 200+ 9% + 150+ 7% + 100+ 8% + 100+ 13.5% + 150) + (1% + 100+ 3% + 6% + 200+ 8% + 7.5% + 150+ 3% + 50% + 3% + 50+ 3.5% + 50+ 4% + 50+ 3.6% + 40% + 10%)/3530.81.25.25%-4(h)
As can be seen from the above, under the same condition, the larger the occupied ratio of the ue with less remaining power is, the larger the TAU period calculated according to the scheme provided by the embodiment of the present invention is, that is, the number of times of waking up the ue with less remaining power is reduced, so as to ensure the energy saving effect of the ue.
(2) Ensuring the number of the user terminals of different grades to be constant: the first-level user terminal accounts for 5%, the second-level user terminal accounts for 10%, the third-level user terminal accounts for 10%, the fourth-level user terminal accounts for 20%, the fifth-level user terminal accounts for 20%, the sixth-level user terminal accounts for 15%, the seventh-level user terminal accounts for 10%, the eighth-level user terminal accounts for 5%, the ninth-level user terminal accounts for 5%, and the tenth-level user terminal accounts for 0%;
when the first traffic class is 10%, the second traffic class is 15%, the third traffic class is 20%, the fourth traffic class is 20%, the fifth traffic class is 15%, the sixth traffic class is 5%, the seventh traffic class is 5%, the eighth traffic class is 5%, the ninth traffic class is 4%, and the tenth traffic class (packet frequency is 30 hours/Time) is 1%, the TAU cycle Time _ TAU is 30/((0.5% + 50+ 2% + 100+ 3% + 100+ 8% + 200+ 10% + 200+ 9% + 150+ 7% + 100+4 + 50+ 4.5% + 50+ (1% + 100+ 3% + 150+ 6% + 200+ 8% + 200+ 7.5% + 150+ 3% + 50+ 3.5% + 50+ 4.5% + 50+ 3.6% + 40% + 30%)/(51.54)-4(h)；
When the first traffic class is 5%, the second traffic class is 10%, the third traffic class is 10%, the fourth traffic class is 15%, the fifth traffic class is 20%, the sixth traffic class is 10%, the seventh traffic class is 10%, the eighth traffic class is 10%, the ninth traffic class is 5%, and the tenth traffic class (packet frequency is 30 hours/Time) is 5%, the TAU period Time _ TAU is 30/((0.5% + 50+ 2% + 100+ 3% + 100+ 8% + 200+ 10% + 200+ 9% + 150+ 7% + 100+4 + 3% + 100+ 6% + 100+ 8% + 100+ 6% + 100+ 4.5% + 50) + (0.5% + 50+ 2% + 50) + (6% + 150+ 10% + 50))/30.-4(h)；
It can be known from the above that, under the same condition, the larger the proportion of the user terminals with long packet sending time intervals is, the smaller the TAU period calculated according to the scheme provided by the embodiment of the present invention is, that is, it is avoided that the user terminals with long packet sending time intervals cannot be woken up for the time when the user terminals need to wake up the mobile phone.
In summary, the technical scheme provided by the embodiment of the invention can be awakened up and down in time on the basis of ensuring the power saving of the user terminal, so that the operation of other application platforms on the user terminal is not delayed.
In the method for configuring a TAU period provided in the foregoing embodiment, all services that can be used by a user terminal served by a base station are classified according to different packet sending time intervals according to the packet sending time intervals, then all user terminals served by the base station are classified according to the obtained remaining power of each user terminal served by the base station, that is, the user terminals served by the base station are classified according to the amount of the remaining power, and finally the TAU period is calculated according to the maximum value of the packet sending time intervals of all user terminals served by the base station, the number of the user terminals corresponding to each type of service, and the number of the user terminals at each level according to a preset formula.
