Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an energy saving method and apparatus, and a mobility management node.
Background
With the development of the application of the internet of things, more and more terminals of MTC (Machine type communication) specialized for Machine communication are provided. The service life of the battery of the MTC terminal is a key factor affecting the service life of the MTC terminal, and therefore, it is very necessary to reduce the power consumption of the MTC terminal.
In a Narrow-Band Internet of Things (NB-IoT) based on a honeycomb, a terminal enters a PSM by depending on an energy Saving Mode (PSM) mechanism, so that the Power consumption of the terminal is reduced. The principle of the PSM mechanism is: if the terminal supports the PSM mechanism, the terminal includes a timer of the PSM in an attach request when transmitting the attach request (english name: attach request), and the network determines a value of the timer of the PSM and transmits the value to the terminal, thereby establishing the timer of the PSM. Referring to fig. 1, the state transition procedure of the terminal in the PSM mechanism is as follows: when the terminal is switched from the connected mode to the idle mode, a timer of the PSM starts to time, after the timer of the PSM is overtime, a mobile Management node (MME for short) judges that the terminal enters the PSM, and meanwhile, the terminal closes an Access Stratum (Access Stratum) to save power consumption. In addition, after the terminal enters the PSM, the UE exits the PSM only when the UE needs to send Mobile Originating (MO) data or a periodic Tracking Area Update (TAU)/Routing Area Update (RAU) timer expires and a periodic TAU/RAU needs to be executed.
As described above, after the service traffic of the terminal is interrupted, the terminal is enabled to enter the idle mode quickly, so that the start timer of the PSM mechanism starts to time, the terminal can enter the PSM quickly, and the power consumption of the terminal is saved. However, when the terminal enters the idle mode and needs to send the MO data, the terminal needs to re-enter the connected mode, and the terminal enters the connected mode from the idle mode and needs to perform a series of signaling flows, so that rapidly entering the idle mode by the terminal may cause very frequent signaling interaction between the network and the terminal, which increases network signaling overhead.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The basic principle of the technical scheme provided by the embodiment of the invention is as follows: when receiving an attachment request sent by a terminal, acquiring a service type of the terminal according to the attachment request, and further acquiring a delay time length and a data packet interval time length corresponding to the service type of the terminal, when service flow of the terminal is interrupted, judging the delay time length and the data packet interval time length to determine whether to control the terminal to enter an idle mode, namely determining whether to control the terminal to enter the idle mode according to service characteristics, so that contradiction between rapid entering of the terminal into the idle mode and network signaling overhead can be balanced.
Based on the above, an embodiment of the present invention provides an energy saving method, specifically, as shown in fig. 2, the method includes the following steps:
and S11, determining the service type of the terminal according to the attachment request sent by the terminal.
S12, determining the delay time length corresponding to the service type and the data packet interval time length corresponding to the service type according to the service type.
It should be noted that the delay time length corresponding to each service type may be preset by a person skilled in the art according to an empirical value or historical data, or may be obtained by performing a simulation experiment according to the packet interval time length of each service type. In the embodiment of the present invention, the delay time length corresponding to each service type is not specifically limited, and may be set according to different requirements. Correspondingly, the delay time length corresponding to each service type can be adjusted according to different requirements.
And S13, judging whether the delay time length is less than the interval time length of the data packet.
It should be noted that, the process of determining whether the delay time length is smaller than the packet interval time length in step S13 may be performed when the traffic flow is smaller than a certain threshold traffic flow. Specifically, when a Mobility Management node (MME) monitors that a traffic flow of a certain service type is less than or equal to a threshold traffic flow, it indicates that the traffic flow may be interrupted, and once the traffic flow is in progress, it needs to determine whether to control the terminal to enter an idle mode and start a timer in an energy saving mode, so it needs to determine whether a delay time length is less than a packet interval time length before the traffic flow is interrupted, and then determine an execution action after the traffic flow is interrupted. Of course, step S13 may be performed at other times before the interruption of the object flow, for example: the step S13 may be performed immediately after the delay time length corresponding to the service type and the packet interval time length corresponding to the service type are obtained.
In step S13, if the delay time length is smaller than the packet interval time length, it indicates that the packet interval time length is longer, and at this time, the terminal is enabled to enter the idle mode quickly, so that the terminal can enter the PSM quickly, thereby saving power consumption of the terminal, and therefore step S14 is executed; if the delay time is greater than or equal to the packet interval time, it indicates that the packet transmission is likely to be required again within the delay time, so step S15 is executed.
And S14, controlling the terminal to enter an idle mode when the service flow of the terminal is interrupted, and starting to time by the timer in the energy-saving mode.
That is, if the delay time length is less than the packet interval time length, the terminal will be triggered to enter the idle mode immediately when the traffic flow of the terminal is interrupted, and the timer triggering the energy saving mode starts to count time.
S15, when the traffic flow of the terminal is interrupted, it is determined whether or not traffic is generated in the terminal within the delay time period.
Since step S15 is executed on the basis that the delay time length is greater than or equal to the packet interval time length, if the traffic of the terminal has not yet ended, there will be packets to be transmitted within the delay time, and therefore the terminal will generate traffic within the delay time length, and if no traffic is generated within the delay time length, it will indicate that the traffic has ended. Therefore, in step S15, if no traffic is generated by the terminal within the delay time period, step S16 is executed, and if traffic is generated by the terminal within the delay time period, step S17 is executed.
And S16, controlling the terminal to enter an idle mode, and starting timing by the timer in the energy-saving mode.
And S17, the control terminal keeps the connection mode.
The energy-saving method provided by the embodiment of the invention obtains the service type of the terminal and obtains the corresponding delay time length and the corresponding data packet interval time length according to the service type, determines whether to enter the control terminal to enter the idle mode when the service flow of the terminal is interrupted by judging the delay time length and the data packet interval time length, and if the delay time length is less than the data packet interval time length, the data packet interval time length corresponding to the service type is longer, so that the control terminal enters the idle mode when the service flow of the terminal is interrupted and a timer of the energy-saving mode starts to time, the terminal can quickly enter the PSM, the power consumption of the terminal is further saved, if the delay time length is more than or equal to the data packet interval time length, the terminal is not immediately controlled to enter the idle mode when the service flow of the terminal is interrupted, but no flow is generated within the delay time length, therefore, the method and the device can avoid the situation that the service data needs to be transmitted just after the terminal enters the idle mode, and further generate signaling overhead, so the embodiment of the invention can balance the contradiction between the terminal rapidly entering the idle mode and the network signaling overhead.
Optionally, as shown in fig. 3, the determining the service type of the terminal according to the attach request sent by the terminal in S11 may specifically be implemented by the following steps:
s111, determining the application service of the terminal according to the Mobile station identification Number (English name: Mobile subscriber International ISDN/PSTN Number, abbreviated as MSISDN) in the attachment request.
Specifically, when the MSISDN is planned by the operator, some fields in the MSISDN corresponding to services with the same service type will be the same, that is, some fields in the MSISDN may represent application services of the terminal, so that the application services of the terminal may be determined according to the MSISDN in the attach request. Illustratively, the application of the terminal may be: intelligent meter reading, intelligent parking and point of Sale (English name: Point of Sale, abbreviated as Point) service.
And S112, determining the type of the terminal according to the International Mobile Equipment Identity (IMEI) in the attachment request.
Specifically, the IMEI usually consists of 15 digits to represent the international mobile equipment identity, and the first six digits are the signal Approval Code (TAC) of the mobile equipment. In practical operation, the IMEI may be processed, that is, the IMEI is processed into 15 bits, and the first 6 bits are taken to determine the type of the terminal. For example: the IMEI is: 355065053311001/01, TAC is: 355065, and thus the type of terminal is determined by 355065.
S113, judging whether the application service of the terminal is matched with the type of the terminal.
It should be noted that, in general, the application service determined according to the MSISDN matches the type of the terminal determined according to the IMEI, when the application service determined according to the MSISDN matches the type of the terminal determined according to the IMEI, the service type of the terminal is determined according to the application service determined according to the MSISDN, and if the application service determined according to the MSISDN does not match the type of the terminal determined according to the IMEI, the service type of the terminal is determined according to the type of the terminal determined according to the IMEI. That is, in step S113, if the application service of the terminal matches the type of the terminal, step S114 is performed; if the application service of the terminal does not match the type of the terminal, step S115 is performed.
And S114, determining the service type of the terminal according to the application service of the terminal.
And S115, determining the service type of the terminal according to the type of the terminal.
Optionally, as shown in fig. 4, the step S12 may specifically determine the packet interval time length corresponding to the service type according to the service type, and the method may be implemented by the following steps:
s121, acquiring distribution information of data packet flow and data packet arrival time corresponding to the service type in the statistical time period.
And S122, acquiring the interval time length of the data packet according to the data packet flow corresponding to the service type in the statistical time period and the distribution information of the arrival time of the data packet.
Specifically, different service types have different data packet sizes and different data packet arrival times, and the data packet sizes and the data packet arrival times of different services present different distribution rules. For example: packet arrival times obey a poisson distribution. Therefore, after the service type of the terminal is determined, the distribution rule of the arrival time of the data packet of the service type can be obtained according to the corresponding data packet flow and the distribution information of the arrival time of the data packet of the service type in the statistical time period, and further the interval time length between the adjacent data packets can be obtained according to the distribution rule of the arrival time of the data packet.
Optionally, the method provided by any of the above embodiments further includes: and when the timing time length of the timer in the energy-saving mode exceeds the value of the timer in the energy-saving mode, controlling the terminal to enter the energy-saving mode.
That is, after the timer of the PSM expires, the control terminal enters the PSM.
It should be noted that, after the PSM timer expires, the terminal may close an Access Stratum (hereinafter referred to AS ") for power saving after entering the PSM, and at the same time, the network side determines that the terminal enters the PSM after the PSM timer expires, and rejects the downlink service and paging, so that the network layer does not send downlink data and paging messages to the terminal any more, and thus, the terminal and the network side are synchronized with respect to the information that the terminal enters the PSM.
Optionally, the method provided by any of the above embodiments further includes: acquiring an Access Point Name (English Name: Access Point Name, APN for short) request in the attachment request;
and determining the value of the timer of the energy-saving mode according to the APN request.
And sending the value of the timer of the energy-saving mode to the terminal.
And the APN request corresponds to the value of the timer of the energy-saving mode one by one.
That is, the timer of the energy saving mode may be determined by an APN request in the attach request, and the network side sends the value of the timer of the final energy saving mode to the terminal through establishment of the APN. And for the terminal requesting the same APN, the timer of the energy saving mode is the same and the value of the timer of the energy saving mode is the same.
The following describes embodiments of the apparatus provided by embodiments of the present invention that correspond to the embodiments of the method provided above. It should be noted that, for the following explanation of the related contents in the embodiments of the apparatus, reference may be made to the above-mentioned embodiments of the method.
