Description
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a method and an apparatus for controlling a power saving mode.
Background
The application market scale of the global Internet of things is rapidly increased, the potential in the future is huge, and the terminal of the Internet of things gradually becomes the focus of industrial attention, wherein how to meet the ten-year endurance time is one of the key points of the research of the field of the terminal of the Internet of things.
The terminal of the internet of things is various and large in quantity, some terminals are in an environment (such as a sensor in a deep well) where batteries are not easy to replace or charging is impossible, and meanwhile, the service life of the terminal is required to be long, generally about ten years, so that low power consumption is a characteristic that the terminal of the internet of things must have. The terminal power consumption needs to be optimized from software/hardware in parallel, wherein protocol flow, product realization, service heartbeat mechanism and the like are involved.
At the protocol stack level, the third generation partnership project enhancement (3GPP R12) introduced a Power Saving Mode (PSM). If the terminal wants to use PSM, it needs to apply for an Active Time timer (Active Time) to the network through non-access stratum signaling in the Attach/Tracking Area Update (TAU)/Routing Area Update (RAU) process. And if the network receives the application of the terminal, configuring Active Time through non-access stratum signaling. After the terminal obtains the network side permission, the terminal starts an Active Time timer after entering an idle state from a connection state, and enters a PSM state after the timer is finished. When uplink data transmission or periodic TAU/RAU is required, the terminal leaves PSM. The network can page the terminal when the terminal is in the Active time phase, and the network can not page the terminal when the terminal is in the PSM phase, but still keeps the registration information.
In the current PSM solution, the terminal REQUESTs to use the PSM state must REQUEST for Active Time by sending Attach REQUEST (Attach REQUEST)/tracking area update REQUEST (TAU REQUEST)/routing area update REQUEST (RAU REQUEST) signaling, the network configures Active Time by ATTACH ACCEPT/TAU ACCEPT/RAU ACCEPT signaling, and the terminal needs to go through a complete TAU/RAU/Attach procedure to use the PSM state. However, a large part of terminals of the internet of things are fixed in position and have no mobility requirement, so that a Tracking Area (TA)/Routing Area (RA) where the terminal is located is not changed generally, and therefore, it is not necessary to perform a TAU/RAU procedure, but the terminal sends the TAU/RAU for applying Active Time, thereby bringing extra signaling burden. In addition, the characteristic that the narrowband internet of things has massive connection is considered, and the air interface resources of the cell are very short, so that the redundant signaling interaction can cause resource waste and influence the network performance.
On the other hand, as shown in fig. 1, the network configured PSM has no periodicity, the configuration is valid once, and the PSM status of the terminal is maintained until the next UE-initiated TAU/RAU/data transmission procedure, and if the terminal does not re-apply for Active Time through TAU/RAU, the PSM status is invalid unless the terminal re-applies for Active Time through initiating TAU/RAU procedure. Therefore, in the prior art, each Time the terminal wakes up from the PSM state, it needs to re-apply for Active Time through the TAU/RAU procedure to re-enter the PSM, otherwise, the terminal cannot re-enter the PSM. This implementation brings a lot of signaling redundancy, which aggravates the resource waste.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
First embodiment
According to an aspect of an embodiment of the present invention, there is provided a method for controlling a power saving mode, as shown in fig. 2, the method including:
The control method of the power saving mode of the embodiment of the invention is applied to the terminal side. In the using process of the terminal, the terminal enters an idle state from a connection state, wherein the terminal in the idle state can be paged by a network side.
When a terminal enters an idle state, the terminal starts an active time timer to start timing. In the embodiment of the invention, after the terminal applies for the power saving mode once, if the terminal needs to enter the power saving mode again, the terminal needs to continue to use the value of the activation time timer adopted when the terminal enters the power saving mode last time when the terminal enters the idle state. That is, in step 202, the timing length of the activation time timer takes the value of the last time the power saving mode was executed.
And 203, entering a second power saving mode when the activation time timer is overtime.
As shown in fig. 5, after the terminal successfully applies for the power saving mode to the network side, when the terminal enters the idle state from the connected state for the first time, the terminal starts the activation time timer recorded in the power saving mode application process, and when the activation time timer times out, the terminal enters the first power saving mode. Wherein the first power saving mode continues until the terminal enters the connected state again. If the terminal enters the idle state again from the connection state, the activation time timer adopted by the first power saving mode is used, when the activation time timer is overtime, the terminal enters the second power saving mode, and then the terminal enters the third power saving mode, the fourth power saving mode and the like according to the same process.
Therefore, the first-time power saving mode and the second-time power saving mode are power saving modes that are entered at non-passage times in chronological order after the terminal successfully applies for the power saving mode. The terminal in the power saving mode cannot be paged by the network side, but the registration information of the terminal is still reserved on the network side.
As can be seen from the above, the method for controlling a power saving mode according to the embodiment of the present invention can, for a terminal supporting the power saving mode, resume the value of the activation time timer used for entering the power saving mode last time when the terminal needs to enter the power saving mode this time. That is, in the embodiment of the present invention, the terminal once applies for the power saving mode is always valid by default, when the terminal wakes up from the once power saving mode, and if the terminal needs to enter the power saving mode again, it is not necessary to resend the related signaling to reapply to the network side, and it is only necessary to continue to use the value of the activation time timer when the terminal last enters the power saving mode, thereby reducing the signaling sending, saving the network resources, and optimizing the network performance.
Preferably, before step 201, the method further comprises:
applying for a power saving mode to a network side in the process of carrying out non-access stratum interaction with the network side;
receiving an activation time timer sent by the network side;
detecting whether to enter an idle state;
starting the activation time timer when entering an idle state;
and when the activation time timer is overtime, entering a first power saving mode.
That is, in the embodiment of the present invention, before step 201, the method further includes a related step in which the terminal applies for the power saving mode to the network side, and enters the power saving mode for the first time after the application is successful. The steps of entering the power saving mode each time after the power saving mode application is successful are the same, namely, whether the power saving mode enters an idle state is detected; when entering the idle state, starting an activation time timer, and when the activation time timer is overtime, entering a power saving mode.
Therefore, if the terminal wakes up from the second power saving mode after step 203, it needs to enter the third power saving mode, and the above steps are repeated. It should be noted that the activation time timer used when entering the third power saving mode is the value of the activation time timer used when entering the second power saving mode.
Further, the applying for the power saving mode to the network side in the process of performing the non-access stratum interaction with the network side includes:
and sending an uplink non-access stratum signaling carrying an application value of the activation time timer to the network side to apply for the power saving mode.
Correspondingly, the receiving the activation time timer sent by the network side includes:
and receiving a downlink non-access stratum signaling which is returned by the network side and carries the activation time timer, wherein the activation time timer is distributed by the network side according to the application value of the activation time timer.
That is, when the terminal applies for the power saving mode to the network side, it can apply for the power saving mode by sending uplink non-access stratum signaling when interacting with the network side at the non-access stratum. For example, the application is made during initial attach, TAU/RAU, uplink data transmission, and the like. It should be noted that, in the embodiment of the present invention, the application time point of the power saving mode depends on the actual occurrence time of the non-access stratum interaction with the network side. For example, the application of the power saving mode is carried out by depending on the processes of initial attachment, TAU/RAU, uplink data transmission and the like, and additional signaling interaction is not initiated for the power saving mode application alone, so that the purposes of reducing signaling interaction and saving resource occupation are achieved.
The specific way of applying for the power saving mode is as follows:
the first method is as follows: when the terminal is initially attached, the terminal carries the PSM-related IE, i.e., the Active Time timer application value, through ATTACH REQUEST signaling. The network allows the terminal to use PSM status and assigns Active Time via ATTACH ACCEPT.
The second method comprises the following steps: the terminal needs to initiate a TAU/RAU process after moving to different coverage areas, PSM related IE is carried through TAU REQUEST/RAU REQUEST signaling, namely, the application value of the activation Time timer is applied, and Active Time is applied. The network allows the terminal to use the PSM state and then allocates Active Time via TAU ACCEPT/RAU ACCEPT signaling.
The third method comprises the following steps: when a terminal initiates uplink service transmission, a PSM-related IE, i.e., an Active Time timer application value, is carried by a signaling (e.g., an explicit service REQUEST) for establishing an uplink. The network allows the terminal to use PSM status and then allocates ActiveTime through uplink established signaling (e.g., DOWNLINK NAS TRANSPORT).
Preferably, after step 203, further comprising:
judging whether the current service state is suitable for using the power saving mode;
if yes, predicting the time length from the time of the next non-access stratum interaction with the network side to the current time;
and when the duration exceeds the preset duration, reapplying the power saving mode to the network side through the process of carrying out non-access stratum interaction with the network side.
That is, after the terminal enters the second power saving mode, if the terminal determines that the current service state is suitable for using the power saving mode, and determines that the Time of next non-access stratum interaction with the network side is farther from the current Time, for example, the next possible TAU/RAU/data transmission/Attach process is farther from the current Time, the terminal may actively apply for the power saving mode and Active Time through the TAU/RAU process. But such operation should be minimized from the point of view of saving signaling overhead.
In addition, if the terminal judges that the current service state is suitable for using the power saving mode, but the terminal does not apply for the power saving mode so far, but the time when the terminal performs non-access stratum interaction with the network side next time is far away from the current time, the terminal can directly apply for the power saving mode to the network side at the current time without waiting for the arrival of the next non-access stratum interaction time, and therefore the use experience of a user is further improved.
Preferably, after step 203, further comprising:
judging whether the activation time timer needs to be changed or not according to the current service state;
if yes, sending an uplink non-access stratum signaling carrying the changed activation time timer to a network side when the non-access stratum interaction with the network side is needed next time;
receiving a downlink non-access stratum signaling returned by the network side, wherein the downlink non-access stratum signaling carries the activation time timer redistributed by the network side according to the changed activation time timer;
modifying the activation time timer in dependence on the reassigned activation time timer.
That is, when the terminal determines that the duration of the current activation time timer is not suitable for the current service state, the terminal may actively apply for modifying the activation time timer to the network side. The terminal actively modifies the activation time timer in two different triggering modes. One is that the terminal adaptively optimizes the duration of the activation time timer according to the traffic volume occurring within the timing time of the accumulated activation time timer. For example, if the terminal detects that no downlink service occurs within the timing time of the activation time timer of a plurality of PSM periods, the terminal may consider that the currently configured duration is too long, and may request to reduce the duration of the activation time timer. Another way is for the user to modify through a device control interface or a higher level application. For example, terminal device maintenance and software update may be set in a certain time period, and the probability of downlink paging in this time period is high, so that the user may extend the activation time timer in this time period to ensure that the terminal can complete upgrade maintenance in time.
Then, when the terminal wishes to change the value of the activation time timer at a certain time, the new value of the activation time timer may be carried in the next TAU/RAU/uplink data transmission at that time point through the corresponding uplink non-access stratum signaling, and if the network agrees with the new activation time timer, the new activation time timer is allocated in the corresponding downlink non-access stratum signaling.
Preferably, after step 203, further comprising:
receiving a downlink non-access stratum signaling which is sent by a network side and carries the activation time timer redistributed by the network side;
modifying the activation time timer in dependence on the reassigned activation time timer.
Preferably, after step 203, further comprising:
that is, when the network side determines that the activation time timer of a certain terminal needs to be changed according to the downlink traffic volume, for example, the network finds that the user has more downlink data and that the downlink data is not completely transmitted for several times, the terminal enters the PSM state due to the timeout of the activation time timer and cannot receive the data, and the activation time timer can be appropriately extended. The network side can allocate a new activation time timer through corresponding downlink non-access stratum signaling in the next terminal TAU/RAU/uplink data transmission, and the terminal needs to use the new activation time timer immediately after receiving the new activation time timer.
The terminal actively requests to modify the activation time timer, or the network side reconfigures the activation time timer for the terminal, so that the terminal modifies the activation time timer, which is not limited to the second power saving mode, and may be any after the terminal successfully applies for the power saving mode.
Preferably, after step 203, further comprising:
judging whether the power saving mode needs to be stopped or not according to the current service state;
if yes, sending an uplink non-access stratum signaling carrying the activation time timer set as a preset value to a network side when the non-access stratum interaction with the network side is needed next time;
and receiving a downlink non-access stratum signaling returned by the network side, and deactivating a power saving mode, wherein the downlink non-access stratum signaling carries the activation time timer with the preset value.
That is, the terminal determines whether the power saving mode needs to be deactivated according to the current traffic state. For example, when the terminal detects a large increase in the uplink data transmission frequency. For example, for a dangerous goods detection terminal, when an abnormal condition is not detected, data transmission and reception are less, and the PSM is suitable for use; however, when an abnormal situation is detected, the frequency of uploading the detection data becomes high as the situation changes, and thus it is not suitable to reuse the PSM.
When the terminal determines that the power saving mode needs to be deactivated according to the current service state, the terminal may apply for activating the time timers to be preset values (for example, bit positions of the bytes are all set to 1 or all set to 0) through corresponding uplink non-access stratum signaling in the next TAU/RAU/uplink data transmission, and if the network agrees that the terminal deactivates the power saving mode, the same special activation time timer, that is, the activation time timer with the preset value, is returned in corresponding downlink non-access stratum signaling.
Preferably, after step 203, further comprising:
and receiving a downlink non-access stratum signaling which is sent by a network side and carries the activation time timer set as a preset value, and deactivating the power saving mode.
That is, the network side determines whether the terminal needs to deactivate the power saving mode according to the downlink traffic of the terminal. For example, when the network detects that the terminal has more frequent data transceiving, it determines that the terminal needs to deactivate the power saving mode. When the network side wants a certain terminal to stop the power saving mode, the network side can configure the activation time timer to be a preset value (for example, all the byte bit positions are set to 1 or all the byte bit positions are set to 0) through corresponding downlink non-access stratum signaling in the next terminal TAU/RAU/uplink data transmission, so that the terminal does not start the power saving mode after receiving the instruction, but the terminal needs to monitor the paging message in real time.
However, whether the terminal actively requests to deactivate the power saving mode or the network side deactivates the power saving mode, the power saving mode may not be limited to the second power saving mode, and may be any power saving mode after the terminal successfully applies for the power saving mode. In addition, after the terminal stops the power saving mode, if the terminal wants to start the power saving mode again, the application can be carried out through the power saving mode application step, when the application is successful, the terminal starts an activation time timer when entering an idle state, and the terminal enters the power saving mode again after the timer is overtime.
In summary, as shown in fig. 5 and fig. 6, in the embodiment of the present invention, after the power saving mode is initially applied, if the terminal does not send uplink non-access stratum signaling to explicitly stop the power saving mode, the default power saving mode is always in effect. And when detecting that the mobile terminal enters the idle state, starting an activation timer, and entering a power saving mode after the timer is overtime. The value of the activation timer may be used to continue with the value of the initial application. After the terminal wakes up from the power saving mode, if the terminal wants to enter the power saving mode again, the terminal does not need to apply again, and when the terminal enters the idle state from the connection state, the terminal directly enters the power saving mode according to the value of the initial application. Therefore, the control method of the power saving mode of the embodiment of the invention greatly reduces signaling overhead and saves air interface resources, thereby optimizing network performance.
