The embodiment of the present application provides a kind of side of the identification information of tracking area TA for obtaining cell re-selection target serving cell Method and equipment are suitable for terminal device and base station.Fig. 2 shows the structure charts of a kind of possible terminal device and base station.In Fig. 2 Shown in terminal device 20 include: wake up radio frequency (Wake-up Radio, WUR) interface 201, principal communication interface (Main Radio) 202 equal components.Base station 21 shown in Fig. 2 includes: principal communication interface 211.It will be understood by those skilled in the art that figure The structure of terminal device 20 shown in 2 does not constitute the restriction to terminal device 20, and terminal provided by the embodiments of the present application is set Standby 20 may include perhaps combining certain components or different component layouts than illustrating more or fewer components.Equally , the structure of base station 21 shown in Figure 2 does not constitute the restriction to base station 21, and base station 21 provided by the embodiments of the present application can be with Including perhaps combining certain components or different component layouts than illustrating more components.

It is specifically introduced below with reference to each component parts of the Fig. 2 to terminal device 20 and base station 21:

WUR interface 201, the wake-up signal sent for receiving base station 21, such as wake-up packet (Wakeup Packet), or Wake-up association sends trigger signal to principal communication interface 202, is in waking up after WUR interface 201 receives wake-up signal The principal communication interface 202 of closed state.Wherein, trigger signal, such as interrupt signal, can be by WUR interface 201 with wired side Formula is wirelessly transmitted to principal communication interface 202, can also be sent to principal communication interface by the processor of terminal device 20 202, such as in systems in practice, the wake-up signal received is transmitted to processor by WUR interface 201, determined by processor be No activation principal communication interface 202, trigger signal is that principal communication interface 202 is sent to by processor at this time；

Principal communication interface 202, for example, long term evolution (Long Term Evolution, LTE), it is new wireless (New Radio, NR) or Wireless Fidelity (Wireless Fidelity, WiFi) interface etc., principal communication interface 202 is generally in closed state, Only in the trigger signal that the processor for receiving WUR interface 201 or terminal device 20 is sent, just it is active, with Data interaction is carried out with the principal communication interface 211 of base station 21.

In the embodiment of the present application, for WUR interface 201 in order to realize low-power consumption, circuit structure is relatively simple, such as WUR The circuit structure of interface 201 may include energy measuring and radio frequency part, can not demodulated complex modulation system, therefore wake up letter It number is also required to using simple modulation system, such as on-off keying (On-Off Keying, OOK) modulation, amplitude shift keying (Amplitude Shift Keying, ASK) or frequency shift keying (Frequency Shift Keying, FSK).WUR interface 201 can be continuously in state of activation, can also activate according to certain time interval, to reduce the power consumption of terminal device 20.Its In, when WUR interface 201 is activated according to certain time interval, terminal device 20 needs to carry out time synchronization with base station 21.WUR The time window that interface 201 is active is properly termed as awake window, the initial time of awake window, awake window when Long and awake window period can be made an appointment by base station 21 and terminal device 20, or be allocated to terminal device by base station 21 20.Fig. 3 is referred to, the period for the awake window of a WUR interface is 120 milliseconds (ms), the when a length of 2ms of awake window Example.

With continued reference to Fig. 2, base station 21 includes principal communication interface 211, and base station 21 can be generated by principal communication interface 211 and be waken up Signal, this is because for current third generation affiliate (3^rdGeneration Partnership Project, 3GPP) mark For standard, the principal communication interface 211 of base station 21 is usually orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) wideband transmitter, and wake-up signal may be narrow band signal, in order to reduce the manufacture of base station 21 at The structure of this and simplified base station 21 can use OFDM wideband transmitter and generate narrowband wake-up signal.Such as by ofdm signal Portion subcarriers are vacant and signal is only transmitted on the corresponding narrowband of wake-up signal, to generate narrow band signal.It needs to illustrate It is that base station 21 in the concrete realization can also individually realize principal communication interface 211 and WUR interface, that is, institute in Fig. 2 The base station 21 shown can also include principal communication interface 211 and WUR interface simultaneously.

In addition, base station 21 shown in Fig. 2 and terminal device 20 configure an antenna, this mainly considers terminal device 20 WUR interface 201 and principal communication interface 202 can share on the same day using under identical or close frequency range carrier case Line, to save the manufacturing cost of terminal device 20 and simplify device structure.Certainly, when the WUR interface 201 of terminal device 20 and master For communication interface 202 when being spaced biggish different frequency range carrier wave on using frequency domain, the WUR interface 201 of terminal device 20 and master are logical Letter interface 202 should configure different antennae.For example, the principal communication interface 202 of terminal device 20 uses 6GHz frequency range, WUR interface 201 Using 1.8GHz frequency range, principal communication interface 202 and WUR interface 201 should configure different antennae at this time.Wherein, when base station 21 is main logical Letter interface 211 and WUR interface individually realizes, and principal communication interface 211 and WUR interface using be spaced on frequency domain it is biggish not When with frequency range carrier wave, the principal communication interface 211 and WUR interface of base station 21 should also configure different antennae.

In the embodiment of the present application, terminal device 20, which carries out cell reselection, can be periodic measurement triggering, be also possible to Event triggering.For example, when terminal device 20 measures the reference signal or synchronization frame of source serving cell and finds to receive function When rate is less than specific threshold, then triggering terminal equipment 20 executes cell reselection, i.e., to N number of candidate service cell of cell reselection The reference signal or synchronization frame of (neighbour cell) measure and determine the target serving district of cell reselection, and then complete Cell reselection.Terminal device 20 determines the specific criterion of target serving district according to the measurement result of N number of candidate service cell, can It is determined by terminal device 20, such as terminal device 20 selects to receive mesh of the prominent candidate service cell as cell reselection Mark serving cell.When terminal device 20 carries out the measurement object difference of cell reselection, terminal device 20 receives what base station 21 was sent The opportunity of synchronization frame is not also identical, such as the reference letter that terminal device 20 is sent based on N number of base station 21 of N number of candidate service cell Number cell reselection is carried out, terminal device 20 receives the network equipment hair of target serving district then after determining target serving district The synchronization frame sent；Or the synchronization frame that terminal device 20 is sent based on N number of base station 21 of N number of candidate service cell carries out cell weight Choosing, terminal device 20 is then before carrying out cell reselection, in N number of base station 21 by the N number of candidate service cell of WUR interface The synchronization frame that each base station 21 is sent respectively, is introduced separately below.

Based on foregoing description, the WUR interface 201 of terminal device 20 can be continuously in state of activation, can also be with certain Time interval activation.Wherein, when the WUR interface 201 of terminal device 20 is continuously in state of activation, no matter N number of candidate base station 21 send synchronization frame with which kind of sending method respectively, and terminal device 20 can pass through WUR interface in first window duration 201 receive the synchronization frame that each candidate base station 21 is sent respectively in N number of candidate base station 21.And in the WUR interface of terminal device 20 In the case that 201 activate at a time interval, each candidate base station 21 uses different transmissions in N number of candidate base station 21 When mode, terminal device 20 needs to use different reception modes, is introduced separately below.

One, it is directed to mode 1, due to the period for the synchronization frame that each candidate base station 21 is sent respectively in N number of candidate base station 21 It is identical as the transmission period of synchronization frame of source base station 21, the synchronization frame that each candidate base station 21 is sent respectively in N number of candidate base station 21 Initial time and source base station 21 send synchronization frame initial time between interval be less than or equal to first window duration, this Sample, terminal device 20 can receive each candidate in N number of candidate base station 21 in first window duration, through WUR interface 201 The synchronization frame that base station 21 is sent respectively.Such as terminal device 20 is received in first window duration by 201 total energy of WUR interface The synchronization frame sent to candidate base station 21 (1).

Two, it is directed to mode 2, due to for the synchronization frame for thering is at least one candidate base station 21 to send in N number of candidate base station 21 The interval begun between moment and the initial time of the transmission synchronization frame of source base station 21 is greater than first window duration, therefore terminal device 20 In first window duration, each candidate base station 21 in N number of candidate base station 21 possibly can not be received by WUR interface 201 and distinguished The synchronization frame of transmission.In this case, terminal device 20 can control that WUR interface 201 is active when a length of One duration, the first duration are greater than first window duration, receive N number of candidate base station 21 to pass through WUR interface 201 in the first duration In the first synchronization frame for sending respectively of each candidate base station 21, wherein each candidate base station 21 is sent out respectively in N number of candidate base station 21 The first synchronization frame sent can be first synchronization frame, each candidate base station 21 that each candidate base station 21 is sent respectively and send out respectively First synchronization frame and second synchronization frame sent, is not specifically limited herein.In the embodiment of the present application, in terminal device 20 After receiving the first synchronization frame that each candidate base station 21 is sent respectively in N number of candidate base station 21, then respectively to each candidate base station 21 the first synchronization frames sent measure, for example, first synchronization frame sent respectively to each candidate base station 21 is surveyed Amount or the second synchronization frame sent respectively to each candidate base station 21 measure or respectively to the transmissions of each candidate base station First synchronization frame and second synchronization frame measure, the measurement result that then measures to first synchronization frame and to Measurement result that two synchronization frames measure is averaging, and is obtained N number of measurement result, and according to N number of measurement result from N number of time Select and determine target serving district in serving cell, then according to receive target BS 21 send the first synchronization frame at the time of, When a length of the second duration less than the first duration that adjustment WUR interface 201 is active, to receive mesh in the second duration The subsequent synchronisation frame that base station 21 is sent is marked, second when, a length of 20 selected target serving cell of terminal device was as current service cell Afterwards, the duration of awake window of the WUR interface 201 in current service cell.Certainly, terminal device 20 can also be according to reception To current service cell the first synchronization frame at the time of, adjust its awake window of WUR interface 201 in current service cell Initial time.

Such as with the first window duration of the WUR interface 201 of terminal device be 2ms, synchronization frame sending cycle is 120ms (and awake window period of WUR interface 201), the start/stop time (system clock) of an awake window be 995ms~ 997ms, the first synchronization frame be target BS 21 send first synchronization frame for, terminal device 20 controls WUR interface first 201 when a length of the first duration 6ms greater than first window duration being active, receive N number of candidate in the first duration First synchronization frame that each candidate base station 21 is sent in base station 21.After determining target serving district, with target serving district It is the serving cell where candidate base station 21 (1), at this point, candidate base station 21 (1) is exactly target BS 21 (1), the week of synchronization frame Phase is 120ms, and (system clock) is at the time of terminal device 20 receives first synchronization frame that target BS 21 (1) is sent For 1000ms, terminal device 20 can be that 1000ms determines target base according to synchronization frame sending cycle 120ms, arrival time Stand 21 (1) transmission second synchronization frame arrival time be 1120ms, and then according to the moment adjust WUR interface 201 be in The initial time of state of activation, and when a length of second duration for adjusting that WUR interface 201 is active, such as passing through WUR After interface 201 receives first synchronization frame that target BS 21 (1) is sent, control WUR interface 201 is in close state, This moment of 1120ms activates WUR interface 201, and control that WUR interface 201 is active when it is a length of less than the first duration The second duration 3ms.In the embodiment of the present application, terminal device can adjust WUR interface 201 in real time according to the actual situation and be in and swash The initial time of state living and the duration being active, so as to guarantee accurate reception target BS 21 (1) hair The power consumption of terminal device 20 is reduced while the subsequent synchronisation frame sent.

Three, it is directed to mode 3, due to the week for the synchronization frame for thering is at least one candidate base station 21 to send in N number of candidate base station 21 Phase is different from the transmission period of synchronization frame of source base station 21, therefore the WUR interface 201 of terminal device 20 can in first window duration It can not receive the synchronization frame that each candidate base station 21 is sent respectively in N number of candidate base station 21.In this case, terminal device The 20 when a length of third durations greater than first window duration that can control that WUR interface 201 is active, in third In duration, the first synchronization frame that each candidate base station 21 is sent respectively in N number of candidate base station 21 is received by WUR interface 201, In, the first synchronization frame that each candidate base station 21 is sent respectively in N number of candidate base station 21 can be each candidate base station 21 and distinguish First synchronization frame and second synchronization frame that first synchronization frame, each candidate base station 21 sent is sent respectively, herein not Make concrete restriction.In the embodiment of the present application, each candidate base station 21 in N number of candidate base station 21 is received in terminal device 20 to distinguish After the first synchronization frame sent, then the first synchronization frame sent respectively to each candidate base station 21 measures, for example, right respectively First synchronization frame that each candidate base station 21 is sent is measured or is synchronized respectively to each candidate base station 21 is sent second Frame is measured or is measured respectively to first synchronization frame and second synchronization frame of the transmission of each candidate base station, then The measurement result that measured to first synchronization frame and the measurement result that second synchronization frame measures is averaging, be there are Target serving district is determined from N number of candidate service cell to N measurement result, and according to N number of measurement result.

In which three, since terminal device 20 can not know each candidate base station 21 in N number of candidate base station 21 in advance The period of synchronization frame is sent respectively, and therefore, to guarantee to be properly received the subsequent synchronisation frame of the transmission of target BS 21, terminal is set Standby 20 it needs to be determined that target BS 21 sends the period of synchronization frame out, and specific implementation process includes but is not limited to following two, under Face is introduced respectively.

As an example, terminal device 20 according to receive target BS 21 send the first synchronization frame at the time of or root According at the time of the first synchronization frame for receiving the transmission of target BS 21 and at the time of receiving the second synchronization frame of the transmission of target BS 21 It determines that target BS 21 sends the period of synchronization frame, and then according to the calculated period and receives the subsequent of the transmission of target BS 21 At the time of synchronization frame, when a length of the 4th duration less than third duration that adjustment WUR interface 201 is active, the 4th The subsequent synchronisation frame that target BS 21 is sent is received in duration, the 4th duration is that 20 selected target serving cell of terminal device is made Behind current service cell, the duration of awake window of the WUR interface 201 in current service cell.Certainly, terminal device 20 At the time of can also be according to the first synchronization frame for receiving current service cell, or according to receiving the first of current service cell The synchronization frame sending cycle of at the time of synchronization frame and the second synchronization frame and current service cell adjusts its WUR interface 201 and is working as The initial time of awake window in preceding serving cell.

Such as with the window duration of WUR interface 201 be 2ms, synchronization frame sending cycle is 120ms (namely WUR interface 201 awake window period), the initial time (system clock) of an awake window is 995ms~997ms, the first synchronization frame For first synchronization frame sent for target BS 21, terminal device 20 controls what WUR interface 201 was active first Shi Changwei is greater than the third duration 6ms of first window duration, and each candidate's base in N number of candidate base station 21 is received in third duration It stands 21 first synchronization frame sent respectively, and after determining target serving district, receive that target BS 21 sends the Two synchronization frames.It then is the serving cell where candidate base station 21 (1) with target serving district, terminal device 20 receives candidate Base station 21 (1), that is, target BS 21 (1) send first synchronization frame at the time of (system clock) be 1000ms, terminal It is for 1120ms at the time of second synchronization frame that the reception of equipment 20 target BS 21 (1) is sent, thus terminal device 20 may be used The period for determining that target BS 21 (1) sends synchronization frame is 120ms, and terminal device 20 can determine target BS 21 (1) in turn It is 1240ms at the time of the third synchronization frame of transmission reaches, and then WUR interface 201 is adjusted according to the moment and is active Initial time, and when a length of 4th duration for adjusting that WUR interface 201 is active, such as connect in terminal device 20 Receive target BS 21 (1) send second synchronization frame after, control WUR interface 201 be in close state, 1240ms this Moment reactivation WUR interface 201, when a length of the 4th duration less than third duration that control WUR interface 201 is active 3ms.In the embodiment of the present application, the terminal device starting that adjustment WUR interface 201 is active in real time according to the actual situation Moment and the duration being active, so as to guarantee the accurate subsequent synchronisation for receiving target BS 21 (1) and sending The power consumption of terminal device 20 is reduced while frame.

It as another example, further include the candidate in the synchronization frame that each candidate base station 21 is sent in N number of candidate base station 21 The cycle information for the synchronization frame that base station 21 is sent, such terminal device 20 are synchronous in receive the transmission of target BS 21 first After frame, just can according to receive target BS 21 send the first synchronization frame at the time of determine target BS 21 send under together Step-frame reaches the moment, and according to moment dynamic adjustment WUR interface 201 be active when it is a length of less than the 5th duration The 6th duration, in the 6th duration receive target BS 21 send subsequent synchronisation frame, the 6th duration is terminal device After 20 selected target serving cells are as current service cell, awake window of the WUR interface 201 in current service cell Duration.Certainly, at the time of terminal device 20 can also be according to the first synchronization frame for receiving current service cell, its WUR is adjusted The initial time of awake window of the interface 201 in current service cell.

Such as with the 201 window duration of WUR interface of terminal device 20 be 2ms, synchronization frame sending cycle be 120ms (and The awake window period of WUR interface 201), the start/stop time (system clock) of an awake window is 995ms~997ms, the One synchronization frame be target BS 21 send first synchronization frame for, terminal device 20 control WUR interface 201 be in activation shape When a length of the 5th duration 6ms greater than first window duration of state, receives each time in N number of candidate base station 21 in the 5th duration Select first synchronization frame that base station 21 is sent respectively.It is candidate base with target serving district after determining target serving district The serving cell stood where 21 (1), terminal device 20 receive candidate base station 21 (1), that is, target BS 21 (1) is sent For at the time of first synchronization frame being 1000ms, first synchronization frame that terminal device 20 is sent according to target BS 21 (1) The target BS 21 (1) of middle carrying sends the period 120ms of synchronization frame, determines that target BS 21 (1) sends second synchronization frame It is 1120ms at the time of arrival, and then the initial time and be in sharp that WUR interface 201 is active is adjusted according to the moment When a length of the 6th duration less than the 5th duration of state living, such as receive what target BS 21 (1) sent in terminal device 20 After first synchronization frame, control WUR interface 201 is in close state, in this moment of 1120ms reactivation WUR interface 201, control WUR interface 201 processed be active when it is a length of less than the 6th duration 3ms of the 5th duration.In the embodiment of the present application, terminal Equipment adjusts duration at the time of WUR interface 201 is active and being active in real time according to the actual situation, from And the power consumption of terminal device 20 can be reduced while guaranteeing the accurate synchronization frame for receiving target BS 21 (1) transmission.

In this case, terminal device 20 can control that WUR interface 201 is active when a length of first when Long, the first duration is greater than first window duration, to receive what target BS 21 was sent by WUR interface 201 in the first duration First synchronization frame, wherein the first synchronization frame can be first synchronization frame of the transmission of target BS 21, target BS 21 is sent First synchronization frame and second synchronization frame, are not specifically limited herein.In the embodiment of the present application, it is received in terminal device 20 After the first synchronization frame that target BS 21 is sent, at the time of according to the first synchronization frame for receiving the transmission of target BS 21, WUR is adjusted When a length of the second duration less than the first duration that interface 201 is active, to receive target BS in the second duration The 21 subsequent synchronisation frames sent, second when a length of 20 selected target serving cell of terminal device as current service cell after, The duration of awake window of the WUR interface 201 in current service cell.Certainly, terminal device 20 can also work as according to receiving At the time of first synchronization frame of preceding serving cell, the starting of its awake window of WUR interface 201 in current service cell is adjusted Moment.Concrete example is with the citing in the two of example IV, and details are not described herein.

Three, it is directed to mode 3, the period of synchronization frame and the period of the transmission synchronization frame of source base station 21 are sent due to target BS 21 Difference, the interval that target BS 21 sends the initial time of synchronization frame and source base station 21 is sent between the initial time of synchronization frame are big In first window duration, in this way, terminal device 20 in first window duration, possibly can not receive the same of the transmission of target BS 21 Step-frame.

In which three, since terminal device 20 can not know that target BS 21 sends the period of synchronization frame in advance, because This, for the subsequent synchronisation frame for guaranteeing to be properly received the transmission of target BS 21, terminal device 20 is it needs to be determined that target BS out 21 send the period of synchronization frame, and specific implementation process includes but is not limited to following two, is introduced separately below.

As an example, terminal device 20 according to receive target BS 21 send the first synchronization frame at the time of or root According at the time of the first synchronization frame for receiving the transmission of target BS 21 and at the time of receiving the second synchronization frame of the transmission of target BS 21 It determines that target BS 21 sends the period of synchronization frame, and then according to the calculated period and receives the subsequent of the transmission of target BS 21 At the time of synchronization frame, when a length of the 4th duration less than third duration that adjustment WUR interface 201 is active, the 4th The subsequent synchronisation frame that target BS 21 is sent is received in duration, the 4th duration is that 20 selected target serving cell of terminal device is made Behind current service cell, the duration of awake window of the WUR interface 201 in current service cell.Certainly, terminal device 20 At the time of can also be according to the first synchronization frame for receiving current service cell, or according to receiving the first of current service cell The synchronization frame sending cycle of at the time of synchronization frame and the second synchronization frame and current service cell adjusts its WUR interface 201 and is working as The initial time of awake window in preceding serving cell.Concrete example is with the citing in the three of example IV, and details are not described herein.

It as another example, further include the week for the synchronization frame that target BS 21 is sent in the synchronization frame that target BS 21 is sent Phase information, such terminal device 20, just can be according to reception targets after the first synchronization frame for receiving the transmission of target BS 21 Next synchronization frame that target BS 21 is sent is determined at the time of the first synchronization frame that base station 21 is sent reaches the moment, and according to When a length of the 6th duration less than the 5th duration that moment dynamic adjustment WUR interface 201 is active, at the 6th The subsequent synchronisation frame that target BS 21 is sent is received in long, the 6th duration is 20 selected target serving cell conduct of terminal device Behind current service cell, the duration of awake window of the WUR interface 201 in current service cell.Certainly, terminal device 20 is gone back At the time of can be according to the first synchronization frame for receiving current service cell, its WUR interface 201 be adjusted in current service cell Awake window initial time.Concrete example is with the citing in the three of example IV, and details are not described herein.

S74: terminal device 20 obtains the identification information of the affiliated TA in target serving district from the synchronization frame；

S75: terminal device 20 determines the need for carrying out TA update according to the identification information of the affiliated TA in target serving district, When not needed, the principal communication interface of the terminal device is kept to be in close state.

In the embodiment of the present application, the mark letter of the affiliated TA in target serving district is obtained from synchronization frame in terminal device 20 After breath, terminal device determines whether to carry out TA update, the tool that TA updates according to the identification information of the affiliated TA in target serving district The process that body process is updated with TA in embodiment shown in Fig. 4, details are not described herein.

The embodiment of the present application provides a kind of data transmission method, is described in detail below:

In scene as shown in figure 12, base station (a kind of network equipment) can with user equipment (User Equpiment, UE) (terminal device is also referred to as herein) to carry out data transmission.Base station can send wake-up signal, as wake-up association with it is synchronous Frame；UE is configured with WUR module and principal communication module, and can receive the wake-up signal that base station is sent by WUR module.From production From the point of view of in product form, send wake-up signal can be base station, be also possible to UE.Fig. 5 C is the example that base station sends wake-up signal Son.Scene of the present invention is that IDLE state UE is moved to current service cell edge generation cell reselection as shown in fig. 13 that The case where scene, each cell, is then as shown in figure 12, i.e., the base station of each cell can send wake-up signal.

Assuming that UE, which is configured with, wakes up radio frequency (Wake-up Radio, WUR) interface, and when UE is in idle (IDLE) state, UE Principal communication interface (such as LTE/NR interface) can be closed and open WUR interface.WUR can be continuously in state of activation, can also be with work Make in intermittent work mode as shown in Figure 3.

After UE introduces WUR interface, base station is in addition to sending wake-up association, and also transmittable synchronization frame, synchronization frame is also to wake up One kind of signal, can be by the WUR interface of UE.WUR synchronization frame can be described as WUR beacon (Beacon) frame, abbreviation synchronization frame again Or beacon frame.The effect of synchronization frame includes one or more of following effects:

So that UE when principal communication interface is closed, WUR interface is opened, can execute measurement process based on synchronization frame.Example Such as, UE determines the need for executing cell reselection based on the measurement of synchronization frame.It goes to connect in this way, UE is just not necessarily to open principal communication connection PSS/SSS and cell reference signals are received, to achieve the purpose that power saving.

If the WUR of UE works in intermittent work mode, UE need to reception based on synchronization frame and base station keep Timing Synchronization, So that the awake window of UE is unlikely to miss the wake-up association that may be arrived since clock drift is excessive.

Assuming that UE based on the synchronization frame for receiving former serving cell, determines to carry out cell reselection, and by receiving Target cell Synchronization frame has determined new demand servicing cell.At this point, the openable principal communication interface of UE and pass through new demand servicing cell synchronous signal and system The reception of message determines new demand servicing cell ID (new demand servicing cell ID need to be determined by the reception of PSS/SSS and MIB), To complete cell reselection.Then, the system message (such as SIB1) of the openable principal communication interface new demand servicing cell of UE is come true The TAI of new demand servicing cell is determined, to decide whether to execute TA renewal process.In the above process, UE needs to open principal communication Interface carries out the reception of PSS/SSS and system message (MIB&SIB1), it is clear that compares power consumption.

For these reasons, the present invention proposes that the basic thought for reducing the solution of UE power consumption is: it is same that base station sends WUR Step-frame, wherein carrying TA identification information belonging to base station.In this way, being connect after UE carries out cell reselection without opening principal communication Mouth receives the SIB1 of new demand servicing cell to obtain the TAI of new demand servicing cell, and only need to be according to the WUR of the new demand servicing cell received Synchronization frame, UE are that can be determined whether to be removed from the cell that the TA List of body preservation is included, and then determine the need for opening master Communication interface is to execute TA renewal process.

The solution of the present invention makes IDLE state UE without activating, and cell reselection can be completed in principal communication interface and new demand servicing is small The acquisition of the affiliated TA in area and the judgement for whether needing to execute TA renewal process, so that UE more power saving.

It also may include base station identification information or cell identity information in the WUR synchronization frame that base station is sent.In this way, UE is being executed When cell reselection, it may not be necessary to open principal communication interface and go the PSS/SSS and MIB that receive new demand servicing cell to obtain new demand servicing Cell ID, and only by receiving the WUR synchronization frame of new demand servicing cell, it can be obtained the mark of new demand servicing cell, to complete Cell reselection.It should be noted that including cell identity information and TA identification information in the WUR synchronization frame that base station is sent, this two Person is independent from each other, i.e., WUR synchronization frame may include any one of cell identity information and TA identification information, or wrap simultaneously Include two.

As shown in figure 12, WUR Beacon, that is, WUR synchronization frame, TA ID are to send TA belonging to the cell of WUR Beacon TA identification information, Cell ID be send WUR Beacon cell cell identity information.

In this way, UE is in moving process for IDLE state by carrying TA identification information and cell identity information in WUR synchronization frame In without activating principal communication interface that cell reselection can be completed, to reduce UE power consumption.Only when UE is according to the WUR of new demand servicing cell TA identification information judgment entrained by synchronization frame itself has moved out cell included by the TA List that network side is oneself configuration When, it just needs to open principal communication interface and executes TA renewal process.IDLE state UE executes TA renewal process by new demand servicing cell Signalling exchange process is as shown in Figure 4.The process is the prior art of existing 3GPP standard, therefore detailed process repeats no more.

Above-mentioned TA identification information can be TAI, be also possible to a part of TAI, or can based on the other of TAI generation For identifying the information of the affiliated TA in base station.For example, TAI is made of PLMN and TAC, and PLMN is for identifying network Service Operation Quotient a, it is contemplated that frequency range is general in areal only can distribute to an operator, therefore TA identification information can not include PLMN, and only include TAC, to reduce TA identification information length, to reduce the length of WUR synchronization frame, save expense.TA mark Knowing information can also be a part of TAC, such as low several positions of TAC.Similarly, cell identity information can be in Current standards PCI (Physical-layer Cell Identity, physical-layer cell identifier), is also possible to a part of PCI, either The other information that can be used for identifying base station or cell generated based on PCI.

The WUR synchronization frame of each cell is sent by base station regularity.For example, synchronous by base station periodicity sending WUR Frame, sending cycle can be configured by base station, alternatively, being that standard is predetermined.For the former, base station can be disappeared by RRC, system The upper layer informations such as breath, MAC CE, or by physical layer signalings such as DCI, the period of WUR synchronization frame is configured.May be used also base station Configuration sends time and/or frequency resource used in WUR synchronization frame, the i.e. time domain and/or frequency domain resource of WUR synchronization frame point Match.In addition, base station can also configure the start time for sending WUR synchronization frame, that is, at the time of sending first WUR synchronization frame.Specifically , which can be indicated by time migration.For example, the time migration can be first WUR synchronization frame and base station Time interval between configuration information.

The sending cycle of the WUR synchronization frame of different community can be same or different.WUR synchronization frame in different community is sent out It send in period identical situation, the WUR synchronization frame sending time of different community may be roughly the same, or there are time migrations.If The WUR of UE is in sustained activation state, then UE can always receive the WUR synchronization frame of other cells by WUR, and is based on connecing At least two WUR synchronization frames of the same cell received judge the WUR synchronization frame sending cycle of the cell.But if UE is used Intermittent activation pattern as shown in Figure 3, then under different situations UE listen to other cells WUR synchronization frame method not It is same:

Case 1: assuming that the WUR synchronization frame sending cycle of different community is identical, and the WUR synchronization frame of different community is sent Opportunity is also roughly the same, as shown in Figure 5A；

The WUR synchronization frame of different community sends opportunity can be identical, but the WUR of neighboring community is synchronized in this case Frame is easy to interfere with each other.Therefore, the WUR synchronization frame of different community transmission opportunity can be configured to roughly the same.For example, being respectively positioned on Same subframe, but occupy different mini-slot.Specifically, when " roughly the same " refers to that the WUR synchronization frame of neighboring community is sent Between between offset be no more than UE awake window duration.This point can be realized by the coordination between base station.Due to adjacent small The opportunity that area sends WUR synchronization frame is roughly the same, therefore UE WUR ready to receive to other cells in the awake window of itself is same Step-frame determines new demand servicing cell based on the measurement of these WUR synchronization frames and completes cell reselection.

Case 2: assuming that the WUR synchronization frame sending cycle of different community is identical, but the WUR synchronization frame of different community is sent There are larger offsets between opportunity, as shown in Figure 5 B；

Here " larger offset " refers to that the offset between the WUR synchronization frame sending time of neighboring community is more than the wake-up of UE Window duration.In this case, when needing to be implemented cell reselection when the former serving cell signal of UE discovery is weaker, in awake window In can not hear the WUR synchronization frames of other cells.At this point, the WUR interface of oneself can be kept state of activation for a period of time by UE (not less than the sending cycle of WUR synchronization frame), to receive the WUR synchronization frame of other cells, so that it is same according to other cells WUR The measurement of step-frame determines new demand servicing cell.Since the sending cycle of the WUR synchronization frame of different community is identical, therefore UE is based on receiving New demand servicing cell a WUR synchronization frame, that is, can determine the sending instant of subsequent WUR synchronization frame.

Case 3: assuming that the WUR synchronization frame sending cycle of different community is different, and the WUR synchronization frame of different community is sent There are larger offsets between opportunity, as shown in Figure 5 C；

The definition of " larger offset " is the same as Case 2.In this case, similar Case 2, UE are also required to connect the WUR of oneself Mouth keeps state of activation for a period of time, to receive the WUR synchronization frame of other cells, to complete cell reselection.But due to The WUR synchronization frame sending cycle of different community is different, and UE is not aware that the WUR synchronization frame sending cycle of new demand servicing cell, therefore There are two types of the WUR synchronization frame sending cycles that method can make UE acquisition new demand servicing cell at this time.A kind of method is that the WUR of UE connects Mouth is kept for one section of long period of state of activation, until receiving at least two WUR synchronization frames from new demand servicing cell, UE base The subsequent synchronisation frame that can be obtained the sending cycle of new demand servicing cell in the distance between two neighboring WUR synchronization frame, and then obtain Sending time；Another method is that the WUR synchronization frame sending cycle of itself is carried in the WUR synchronization frame that base station is sent, this Sample, the WUR synchronization frame that UE receives new demand servicing cell can determine subsequent synchronisation frame according to its sending cycle carried Sending time.Second method makes the WUR interface of UE that state of activation need not be kept (to receive one of new demand servicing cell for a long time WUR synchronization frame), but it is elongated to will cause WUR synchronization frame, and instruction expense becomes larger.

If the predefined different community WUR synchronization frame sending cycle of standard is identical and sends that opportunity is roughly the same or network side The information is indicated, then UE obtains the WUR synchronization frame of other cells using the method for Case 1；If the predefined difference of standard is small WUR synchronization frame sending cycle in area is identical or network side indicates the information, but UE do not know different community sending time whether Roughly the same, then UE obtains the WUR synchronization frame of other cells using the method for Case 2；If UE is synchronous to different community WUR Frame sending cycle it is whether identical and send opportunity it is whether roughly the same not can determine that, then UE using the method for Case 3 come Obtain the WUR synchronization frame of other cells.

It is synchronous using same carrier transmission WUR that the method for above-mentioned acquisition other cells WUR synchronization frame is suitable for different community The case where frame, i.e. UE, are when receiving WUR synchronization frame without carrying out frequency domain switching.If the carrier frequency of different community transmission WUR synchronization frame Difference, but standard predefines the set that may be used to send the carrier frequency of WUR synchronization frame, then and UE can listen to each possible hair in turn The potential carrier frequency (a period of time is resident i.e. on each potential carrier frequency) of WUR synchronization frame is sent, and according to above-mentioned three kinds of situation (Case 1~Case 3) on each potential carrier frequency respective operations are executed, matched with receiving WUR synchronization frame in adjacent area that may be present and correlation Confidence ceases (sending cycle of WUR synchronization frame and time migration etc.).
