Description

Method and device for adjusting DRX period of intelligent terminal in idle state

Technical Field

The present invention relates to the field of intelligent terminal communication, and in particular, to a method and an apparatus for an intelligent terminal to adjust a Discontinuous Reception (DRX) cycle in an idle state.

Background

With The popularization of The 3Generation mobile communication technology (3G) wireless communication system and The continuous improvement of The 4Generation mobile communication technology (4G) technology, The data processing capability of The smart terminal is continuously enhanced and The functions are continuously increased. In recent years, the rapid development of intelligent operating systems has made intelligent terminals not only be communication tools, but also be necessities for work, life and entertainment. The increasingly abundant services bring convenience and fun to consumers, meanwhile, great challenges are provided for the battery endurance of the intelligent terminal, and the problem of power consumption becomes an important factor influencing the use of the intelligent terminal.

To reduce power consumption and extend the standby time of the smart terminal, a DRX power saving mechanism is introduced in the 3rd generation Partnership Project (3 GPP) standard. The basic idea is as follows: and when the intelligent terminal does not receive and transmit data, the intelligent terminal enters a sleep state, and a receiving unit of the intelligent terminal is closed, so that the purpose of reducing the power consumption of the intelligent terminal is achieved. Specifically, the DRX technique periodically monitors a channel and receives downlink traffic in a specific time period negotiated by an intelligent terminal and a network side, and does not need to be continuous all the time.

At present, DRX technology is adopted in both the second generation Global System for mobile communication (GSM) System and the third generation Universal Mobile Telecommunications System (UMTS) System, or the new generation Long Term Evolution (LTE) System, which have different differences. Generally, however, the DRX technology mainly includes different processing mechanisms of the intelligent terminal in an IDLE state (IDLE) and a CONNECTED state (CONNECTED). The idle state refers to that the intelligent terminal does not perform service processing; correspondingly, the connection state means that the intelligent terminal is performing service processing.

When the intelligent terminal is in an idle state, the intelligent terminal does not have access layer connection and special resources of a user, at the moment, service interaction does not exist between the intelligent terminal and a network terminal, the intelligent terminal only needs to periodically wake up from a sleep period, and a receiver is opened to listen to a Paging Channel (PCCH, aiming at a GSM/UMTS system) or a Control Channel (Physical Downlink Control Channel, PDCCH, aiming at an LTE system) so as to determine whether Downlink data belonging to the intelligent terminal exists or not; if not, the sleep period is continuously entered, and the receiver of the intelligent terminal also enters an off state. Therefore, when the DRX technology is used in the idle state, the main factor affecting the standby power consumption is the length of the paging cycle.

Taking LTE system as an example, the DRX Paging cycle in idle state directly determines the Paging Occasion (PO) on the Paging Frame (PF) of the intelligent terminal. Wherein, PF corresponds to an LTE wireless frame (10 ms); PO corresponds to a certain subframe (1 ms) in one radio frame of LTE. Therefore, through the PF and PO, the smart terminal knows at which time it wakes up to listen for the paging message.

When the intelligent terminal is in an idle state, the length of the DRX period setting has an important influence on the standby power consumption of the intelligent terminal. Most of current intelligent terminals are designed basically according to default DRX configuration parameters of a network side, although a specified final DRX period value is determined by a minimum value between the relevant parameters issued by the network side and the parameters applied and set by the intelligent terminal, the network side pays more attention to the response time of paging, so that parameter values given by the network side are usually small, and the length of the DRX period in an idle state is basically determined by the network side.

In addition, once the DRX period parameter issued by each network cell is confirmed, the network side basically does not actively and dynamically change and adjust the DRX period; in order to ensure the success rate of paging, the network side basically sets at least one paging retry on the core network and the base station respectively, that is, the network side repeatedly issues paging for an intelligent terminal in a continuous DRX cycle and at intervals of several DRX cycles, so as to ensure that the intelligent terminal has multiple opportunities to attempt demodulation successfully in a weak signal or abnormal environment.

Finally, most users of the intelligent terminals basically have relatively fixed learning, working, living places and use habits, and the intelligent terminals are not always in an active state in using related wireless services. For example, in the working or learning process, a user is generally in a relatively fixed place, and most of the places have fixed telephones and broadband networks, so that the dependence on the use of an intelligent terminal is reduced; the use of the intelligent terminal is further reduced after the user goes home to sleep for rest at night; and in some situations (such as going to an unfamiliar place or on a road, etc.), the intelligent terminal is frequently used. Therefore, it is very important how to enable the intelligent terminal to automatically adjust the DRX cycle according to the type of the scene where the user is located.

The registration information list is used for recording information of a network cell accessed by the intelligent terminal, information of the stay time of the intelligent terminal in the network cell and the like, and is also used for carrying out information processing such as statistics on the information of the accessed network cell. The registration information list is established when the intelligent terminal starts DRX period adjustment for the first time, and a new registration information list is not required to be established again for each DRX period adjustment of the intelligent terminal in the follow-up process, and only the information in the registration information list established for the first time is required to be updated.

The working state of the intelligent terminal is divided into an idle state and a connection state. The idle state means that the intelligent terminal does not perform data or signaling interactive processing with the network; the connection state means that data or signaling interaction processing exists between the intelligent terminal and the network. The present embodiment is to process DRX in an idle state of an intelligent terminal, and divide the idle state into a sleep mode and a silent mode according to a scene type (that is, the scene type includes the sleep mode and the silent mode). The sleep mode refers to a scene type of daily rest time, and is mainly defined from a time interval, for example, a time interval from 20 pm to 8 pm can be set as the sleep mode; the silent mode refers to the type of the scene where the daily working hours are located, and is also defined from a time interval, for example, the time interval between 8 o 'clock earlier and 20 o' clock later can be set as the silent mode. The time interval division of the sleep mode and the silent mode can be set according to the actual working time of the user.

S102: classifying and screening the information of the currently registered network cell according to the current network time and the registration information list to obtain a scene type;

the registration information list records information of network cells accessed by the intelligent terminal, and the scene state of the intelligent terminal is determined according to the current time.

DRX cycle adjustment will not be enabled when the smart terminal registers with a network cell in the barring information list. And recording the information of the network cells once the DRX period adjustment fails in the forbidden information list.

Fig. 3 shows a flow chart of registration information list and scene information list cell information acquisition, where a cell in the updated scene information list is regarded as a scene where the intelligent terminal is most likely to reside for a long time and can negotiate to adjust the DRX cycle, and when the intelligent terminal registers in the above cell and meets a certain condition, the scene mode decision module can notify the DRX cycle adjustment module to adjust the DRX cycle.

Fig. 4 shows a scene mode decision flowchart, which distinguishes two kinds of scene mode processing according to the difference of the current system time: the method comprises the following steps that a silent period and a sleep period are provided, wherein in the silent period, a user is considered to be in a relatively fixed state such as working or learning, but downlink incoming calls and data services can arrive at any time, so that the adjustment value of the DRX period in the scene mode is not too long, the DRX period can be automatically and properly prolonged on the intelligent terminal according to the characteristic that a network side can repeatedly send paging messages, and only one paging in the network side can be ensured to be received; in the sleep period, the user is considered to be basically in a sleep state, and the intelligent terminal is not used so much at this time, so that the data service function of the intelligent terminal can be considered to be temporarily closed, and the network side is negotiated to greatly prolong the DRX period.

Fig. 5 is a flowchart of a DRX cycle adjustment module, which has different DRX cycle adjustment processes for two different scene modes, respectively, where in the sleep-period scene mode, the DRX cycle adjustment involves a process of negotiating with the network side, which can be implemented by, but not limited to, an attach (attach) procedure. The attachment process specifically comprises: the intelligent terminal firstly executes a detach flow from the network, and then sends an attach request again, wherein the attach request carries a parameter of an expected DRX period, and the parameter value is greater than a protocol specified value (which is a multiple value of the original DRX period and needs to be supported by the network side in advance), so that the network side can distinguish a special adjustment request belonging to the intelligent terminal; after receiving the request, the network side replies attachment request acceptance (attach accept) or rejection (attach reject) information according to whether the parameters support, and the intelligent terminal judges whether to successfully negotiate DRX cycle adjustment according to the information; in addition, in order to improve the success rate of negotiation, the intelligent terminal has a plurality of retry opportunities carrying different DRX period parameters, and the intelligent terminal considers that the requests fail until all the requests are rejected, and adds the cell into the forbidden information list and quits DRX period adjustment. Optionally, the negotiation process may also be completed through other defined flows in the protocol, and for the GSM/UMTS system, the DRX cycle may be adjusted through a Routing Area Update (RAU) request signaling flow and a network side negotiation; for the LTE system, the DRX cycle can be adjusted by negotiating with the network side through a Tracking Area Update (Tracking Area Update TAU) request signaling procedure, which is similar to the attach request procedure, and the network and the smart terminal side are also required to additionally and simultaneously support a special long DRX cycle value beyond the range specified by the protocol.

The specific implementation steps of this embodiment are as follows:

step S6 is a step of acquiring cell information of the registration information list and the context information list, including:

step S6-0: the intelligent terminal is in a starting or standby state;

step S6-1: the intelligent terminal registers to a new cell when being started or in standby, and the intelligent terminal starts to collect and update the information of the newly registered network cell;

step S6-2: acquiring current system Time, deleting outdated cell information (the Time exceeds Texp so far, the Texp is generally limited by 7 days a week, and the overtime Time of the forbidden information list can be more relaxed) in a registration information list, a scene information list and a forbidden information list, and updating the information of the currently registered network cell into the registration information list;

step S6-3: judging whether the current system time belongs to a sleep mode (generally defined as 11:00pm-8:00am), if so, entering an information updating processing procedure aiming at the sleep mode in the step S6-4, and if not, entering an information updating processing procedure aiming at the silent mode in the step S6-8;

step S6-4: different network cells with the total residence time exceeding the set time period Tduration (generally set to 12 hours) during the sleep mode in the registration information list are counted and sorted from large to small. Selecting a cell (not in the forbidden information list) with the rank of 3 from each network system and updating the cell into a scene information list, wherein the cell is vacant if the cell is insufficient;

step S6-5: judging whether the current registered network cell is in the scene information list, if so, entering step S7-1, otherwise, entering step S6-6;

step S6-6: counting the total residence time of the network cell currently registered in the registration information list, calculating the difference between the network cell and the network cell with the shortest total residence time in the same mode in the scene information list, starting a timer to start timing, and stopping timing and exiting if the intelligent terminal is registered to a new network cell again in the timing process;

step S6-7: after the timer is overtime, the network cell registered currently replaces the ranked network cell, the network cell registered currently is updated to the Home column of the scene information list, and the step S7-1 is carried out at the same time;

step S6-8: counting different cells of which the residence time exceeds Tduration during the silent mode in the registration information list, sorting the cells from big to small, selecting the cell (not in the forbidden information list) with the rank of 5 from each system, and updating the cell to the scene information list, wherein the cell is vacant if the cell is insufficient;

step S6-9: judging whether the current registered network cell is in the scene information list, if so, entering step S7-1, otherwise, entering step S6-10;

step S6-10: and counting the total residence time of the network cells currently registered in the registration information list, calculating the difference value between the network cells with the shortest total residence time in the same mode in the scene information list, and starting a timer to start timing. In the timing process, if the intelligent terminal is registered to a new network cell again, timing is stopped and the intelligent terminal exits;

step S6-11: after the timer is overtime, the network cell registered currently replaces the ranked network cell, the network cell registered currently is updated to the Office column of the scene information list, and the step S7-1 is carried out at the same time;

step S7 is a scene mode decision step, including:

step S7-1: if the current network time is in the sleep mode and the current registered network cell belongs to the 'Home' column in the scene information list, the step S7-2 is entered; if the current network time is in the silent mode and the current registered network cell belongs to the 'Office' column in the scene information list, the step S7-5 is carried out, and if the current registered network cell does not belong to the scene information list, the step S7-2 or the step S7-5 is carried out according to the current system time after the timeout of the waiting timer; wherein, the column "Home" represents a network cell belonging to the sleep mode; the "Office" column represents network cells that belong to the silence mode.

Step S7-2: when the intelligent terminal has no data service interaction within the Tdata time (first set time), the intelligent terminal actively disconnects the service access layer connection which may exist in the intelligent terminal, closes the data service function, and simultaneously gives a prompt message on the interface of the intelligent terminal; if the data service exists in the Tdata time, the user is in an active state, and the intelligent terminal needs to continue waiting until the condition that no data service exists in the Tdata time is met;

step S7-3: the intelligent terminal continues to wait for Tactive1 time (second set time). During the period, if the access layer connection is established and the relevant service data processing is carried out, the intelligent terminal exits from timing until the time timing of Tactive1 is restarted after the intelligent terminal enters an idle state again;

step S7-4: if the intelligent terminal is still in an idle state after the Tactive1 timing is overtime, the intelligent terminal adjusts the DRX period of the sleep mode and enters the step S8-1;

step S7-5: and the intelligent terminal waits for the intelligent terminal to finish the service in progress until the intelligent terminal automatically enters an idle state. And when the intelligent terminal is monitored to enter an idle state, the timer starts timing.

Step S7-6: during Tactive2, if the intelligent terminal establishes access layer connection again for carrying out related services, the intelligent terminal exits timing until the intelligent terminal restarts Tactive2 time timing after entering an idle state again;

step S7-7: if the intelligent terminal is still in an idle state after the Tactive2 timing is overtime, the intelligent terminal performs DRX period adjustment of a silent mode, and the step S8-1 is entered;

step S8 is a flowchart of DRX cycle adjustment, including:

step S8-1: judging the type of DRX cycle adjustment, if the DRX cycle adjustment is in a sleep mode, entering a step S8-2, and if the DRX cycle adjustment is in a silent mode, entering a step S8-7;

step S8-2: the intelligent terminal and the network side negotiate to prolong the DRX period of the intelligent terminal, the initial value of the adjusted parameter generally meets the following conditions, and the maximum value is taken in an allowed range:

i >, the adjusted DRX period is a multiple value of the original DRX period;

ii >, the adjusted DRX period is larger than the DRX period upper limit value specified by the protocol;

iii >, the adjusted DRX period can not exceed the upper limit value of the time delay requirement of the network side for the user waiting paging response;

the parameter negotiation may be performed by, but is not limited to, an attach request procedure, as previously described.

Step S8-3: after receiving the negotiation request, the network side gives an attach request rejection message if finding that the DXR period value requested by the intelligent terminal cannot be met; otherwise, replying the attachment request acceptance message and agreeing to DXR cycle adjustment. After receiving the corresponding reply, if the request is the attachment request agreement, the intelligent terminal enters step S8-5, otherwise, the intelligent terminal enters step S8-4 to check whether the DXR cycle parameters need to be adjusted, and initiates negotiation again;

step S8-4: the intelligent terminal judges whether the currently received request rejection message exceeds the maximum retry number (generally set to 2 times, namely, two times of opportunity negotiation with the network side is available), if not, the adjustment value of the DRX period is reduced, and then the intelligent terminal negotiates with the network side again through the step S8-2; otherwise, the intelligent terminal is not successfully negotiated with the network side to adjust the DRX cycle, the information of the currently registered network cell is required to be added into the forbidden information list, and the DRX cycle adjustment process is quitted;

step S8-5: the intelligent terminal considers that the negotiation with the network side is successful, and immediately adjusts the next DRX period of the intelligent terminal so as to adapt to the new DRX period after the negotiation;

step S8-6: the intelligent terminal monitors the current system time, and when the current time is found to exceed the defined time period of the sleep mode, the intelligent terminal goes to step S7-5 to start DRX cycle adjustment in the silent mode;

step S8-7: if the adjustment is the DRX cycle adjustment of the silent mode, if yes, go to step S8-8, otherwise, end.

Step S8-8: the intelligent terminal calculates a 2-time value of the current DRX period (because a network side has a repeated paging mechanism, the DRX period can still be ensured to receive at least one paging of the network side even if the DRX period is prolonged to 2 times), and compares the value with the upper limit value of the DRX period specified by a protocol, if the value exceeds the upper limit value of the DRX period, the current DRX period is longer, and the step S8-10 is carried out, otherwise, the current DRX period has an adjustment space, and the step S8-9 is carried out;

step S8-9: the intelligent terminal automatically adjusts the DRX period of the intelligent terminal to the original 2 times value without informing a network side, so that the interaction process with the network side is avoided, the network side does not need to be changed, and the step S8-11 is carried out to monitor the system time after the adjustment is finished;

step S8-10: and the intelligent terminal maintains the current DRX period and goes to step S8-11 to monitor the system time. Optionally, the intelligent terminal may also negotiate with the network side to adjust the current DRX to the maximum value allowed by both sides;

step S8-11: the intelligent terminal monitors the current system time, and when the current time is found to exceed the time period of the defined silent mode, the intelligent terminal goes to step S7-2 to start DRX cycle adjustment in the sleep mode;

in the above implementation, DXR cycle adjustment execution in silent mode and sleep mode may be temporarily suspended or terminated due to various factors; for example, when the intelligent terminal is detected to be in a charging state within a certain time, and the current user is judged to be charging the intelligent terminal, the DRX cycle adjustment can be temporarily exited; and the user uses the wireless related service after the DRX period is adjusted, and quits the DRX period adjustment within a period of time after the wireless related service is ended. The wireless related service can be judged to be possible to be reused by the user in the time period according to the using habit, and the DXR cycle is adjusted when the user enters the corresponding scene type again after the wireless related service cannot be reused in a short period; when the signal strength of the registered network cell is monitored to be weaker than a certain value, the DRX period adjustment is quitted, and the paging success rate of the intelligent terminal is prevented from being too low; when the intelligent terminal is registered to a new cell, the DRX adjustment under the original scene type is quitted, the relevant optimization can be carried out aiming at the situation that the new network cell resides in a short time, and the repeated processing caused by the similar ping-pong effect in a communication system is avoided; if the intelligent terminal roams to an operator network to which other non-Subscriber Identity Module (SIM) belongs, the intelligent terminal exits DRX period adjustment in the sleep mode. In addition, after the DRX period is adjusted in the sleep mode, the network side can give out a proper network prompt after the user initiates a call, so that the user is prevented from mistakenly thinking that the user is not connected and hanging up in advance. Finally, the method of the embodiment can provide corresponding options on the interface of the intelligent terminal for the user to select whether to start or not.
