Description

Paging message monitoring method and device

Technical field

This application relates to the field of communications, and in particular to a method and device for monitoring paging messages.

Background technique

With the continuous development of communication technology, more and more terminal devices (for example, wearable devices (WD)) have entered our field of vision. A wearable device can be worn directly on the body or a portable device integrated into the user's clothes or accessories. At present, the main wearable products in the market are in different forms, including smart glasses, smart watches, smart bracelets, idea control, healthy wear, somatosensory control, item tracking, etc.

Wearable devices greatly facilitate our lives, but wearable devices usually require smaller size and lighter weight, which results in shorter battery life of wearable devices. For example, the battery life of a common smart watch is around 24 hours. If more functions are turned on, the power consumption will increase, and the user has to charge it frequently (for example, twice a day) to use it normally. Therefore, how to reduce the power consumption of wearable devices has become an urgent problem to be solved.

detailed description

In order to describe the following embodiments clearly and concisely, a brief introduction of related concepts or technologies is first given:

It should be understood that when the terminal device has been registered to the network, when the terminal device has an RRC connection between the terminal device and the base station, the terminal device is in a connected state; when there is no RRC connection between the terminal device and the base station, The terminal device is in an idle state.

When there is a radio resource control connection between the terminal device and the base station, but there is no connection between the terminal device and the core network, the terminal device is in an inactive state.

Air interface paging mechanism: For the network side, when the core network needs to send data or signaling to the terminal device, or when the terminal device needs to be reattached, the mobility management entity (mobility management entity, MME) can initiate paging. As shown in Figure 1a, the MME initiates the paging process by sending a paging message to the base station. After receiving the paging message, the base station pages the terminal device by sending a paging message to the terminal device. Or, when the cell system information changes, or when the base station needs to notify the terminal equipment to receive information such as earthquake, tsunami warning system (earthquake and tsunami warning system (ETWS) or commercial mobile alert service (CMAS), such as As shown in FIG. 1b, the base station can send a paging message to the terminal device to page the terminal device.

For the terminal device side, the terminal device can receive paging information in a discontinuous reception (DRX) mode in an idle state to save power consumption. As shown in FIG. 1c, a DRX cycle may include multiple radio frames, and some of the radio frames in the multiple radio frames are used to transmit paging information. The partial radio frames used to transmit paging information may be called paging frames. (paging frames, PF). Each paging frame may include multiple subframes, some of the multiple subframes may be used to transmit paging information, and the partial subframes may be referred to as POs. The starting position where the control information of paging information appears on the air interface is fixed, and can be represented by PF and PO. The terminal device can read the physical downlink control channel (physical downlink control channel, PDCCH) control information according to the paging radio network temporary identity (P-RNTI) on the PO corresponding to itself. If the terminal device determines that a paging message is delivered, it then reads the content of the paging message from the physical downlink shared channel (PDSCH) indicated by DCI. The frame number of the PF and the subframe number of the PO corresponding to the terminal device may be obtained according to the international mobile subscriber identification number (IMSI) of the terminal device, the DRX cycle, and the number of POs in the DRX cycle.

Exemplarily, the frame number of PF satisfies formula (1):

SFN mod = T (divN) * (UE_ID mod N) (1)

That is, the frame number of PF is the result of finding the remainder of the system frame number (SFN) and T of the cell.

Where T is the DRX cycle, for example, T is the default paging cycle (defaultPagingCycle) broadcast by the base station in SIB2. For example, the DRX cycle may be 32, 64, 128, or 256 radio frames. N=min(T, nB), nB represents the number of paging packets, that is, the number of paging moments (subframes) included in one paging cycle, that is, the number of paging groups. UE_ID = IMSI mod 4096. For the UE ID, if it is a paging triggered by the MME, the UE ID can correspond to the cell UE Identity in the S1 interface paging message (UE Identity Index Value); if the paging is triggered by the base station, the default UE_ID=0.

The subframe number of PO can be determined according to Table 1, where N/A means Not applicable (Not applicable).

Table 1

Among them, i_s satisfies formula (2):

i_s=floor(UE_ID/N) mod Ns (2)

Among them, Ns=max(1, nB/T). "Floor(UE_ID/N)" indicates that the quotient of (UE_ID/N) is rounded down. For the rest of the parameters, please refer to the relevant description above.

Measuring GAP (hereinafter also referred to simply as GAP): The measurement is divided into intra-frequency measurement and inter-frequency measurement. Among them, the co-frequency measurement means that the cell where the terminal device is currently located and the target cell to be measured are on the same carrier frequency point (center frequency point). Inter-frequency measurement means that the cell where the terminal device is currently located and the target cell are not on a carrier frequency. If the terminal equipment needs to perform inter-frequency measurement (including inter-standard measurement), a simple way is to install two types of RF receivers in the terminal equipment to measure the frequency of the local cell and the frequency of the target cell, but this will It brings about cost increase and mutual interference between different frequency points. Therefore, the 3rd Generation Partnership Project (3GPP) proposed a measurement interval (measurement GAP) method, that is, to reserve a part of time (that is, measure the GAP time). During this time, the terminal device will not send And receive any data, and adjust the receiver to the frequency point of the target cell, perform inter-frequency measurement, and then turn to the current cell when the GAP time ends.

At present, a variety of GAP patterns are defined in the long-term evolution (LTE) or new radio (NR) standard protocols, including uniform GAP Pattern and non-Uniform GAP Pattern . NR can also be called the fifth generation mobile communication technology (5-generation, 5G).

As shown in Figure 2, for uniform GAP Pattern, GAP is evenly distributed. Each box is the location of the GAP, the measurement interval length (MGL) is the length of the GAP, and the measurement interval repetition period (Measurement Gap Repetition Periodicity, MGRP) is the GAP period. In the current standard protocol, the value range of MGRP is {20ms, 40ms, 80ms, 160ms}. The value range of MGRP in LTE may be {40ms, 80ms}, and the value range of MGRP in NR may be {20ms, 40ms, 80ms, 160ms}. The value range of MGL is {1.5ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms}. The value range of MGL in LTE may be {3ms, 6ms}, and the value range of MGL in NR may be {1.5ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms}.

As shown in Figure 3, for non-Uniform GAP, GAP is not evenly distributed. The burst repetition period (burst repetition period) of non-Uniform GAP includes two time periods T1 and T2. T1 is equal to the number of GAPs per burst in the non-Uniform GAP configuration (number of GAPs per burst), and the terminal device measures in the GAP (unshaded box) in T1. In the current standard protocol, T1 can include 13 GAP cycles (MGRP), where MGL is 6 ms and MGRP is 40 ms. The terminal device does not perform measurement in the GAP (shaded box) in T2 (that is, the terminal device suspends measurement, and the terminal device can assume that GAP is not measured in T2).

The base station can configure the GAP Pattern identity (ID) and GAP offset (Offset) for the terminal device through RRC signaling. The terminal device determines GAP related information according to the GAP pattern ID and GAP Offset. Specifically, the terminal device may determine the GAP period and length according to the GAP pattern ID, and determine the starting position of the GAP according to the GAP period and the GAP Offset. Exemplarily, the terminal device determines the starting position of the GAP according to the GAP Offset as follows:

For uniform GAP and non-uniform GAP, the SFN and subframe where the first subframe of each GAP is located satisfy formula (3) and formula (4), respectively:

SFN mod = T Floor (GAP Offset/10) (3)

subframe = GAP Offset mod 10 (4)

Among them, T=MGRP/10; mod stands for the remainder operation; Floor stands for the rounding operation.

For non-Uniform GAP Pattern, the base station can also configure number of GAPs, burst, period, measurement purpose, etc. for the terminal equipment, which is not limited in this application.

An embodiment of the present application provides a method for monitoring a paging message. Taking the first device as a mobile phone and the second device as a wearable device as an example for illustration, as shown in FIG. 8, the method includes:

801. If the first device meets the first condition, the first device sends the first information to the second device.

If the first condition is satisfied, the mobile phone determines that the wearable device monitors the paging message, and the mobile phone can send the first information to the wearable device, and the first information is used to indicate that the mobile phone monitors the paging message for the wearable device.

Among them, the first condition includes any of the following situations:

1) The mobile phone is in idle state or inactive state.

When the mobile phone is in the idle state or inactive state, it can wake up on the corresponding PO to receive the paging message, or wake up on the PO of the wearable device to receive the paging message, so as to save power consumption of the wearable device. The mobile phone and the wearable device can be in the same cell, or the mobile phone and the wearable device can be in different cells, but the mobile phone can receive the paging message of the cell where the wearable device is located.

For example, when an evolved packet core (Evolved Packet Core, EPC) needs to send data or signaling to a mobile phone or a wearable device, the MME can send a paging message to the base station. After receiving the paging message, the base station pages the mobile phone by sending a paging message on the PO of the mobile phone, and pages the wearable device by sending a paging message on the PO of the wearable device. The mobile phone in the idle state or inactive state can wake up on its own PO (obtained according to the calculation method above) to monitor its own paging message, and can be on the PO of the wearable device (for example, the mobile phone can receive the wearable device The configuration parameters of the PO of the wearable device are sent to determine the specific location of the PO of the wearable device) to wake up to listen to the paging message of the wearable device and sleep at other times, thereby reducing power consumption.

Among them, the PO of the mobile phone and the PO of the wearable device may or may not coincide. For example, assume that the PF of the mobile phone and the wearable device are the same, for example, frame 1, the PO of the mobile phone is subframe 1, and the PO of the wearable device is subframe 4. Then, in subframe 1, if the mobile phone finds a P-RNTI, it obtains a paging message from the PDSCH in the same subframe according to the radio resource location indicated by the PDCCH and the MCS, and determines whether the paging message includes the mobile phone ID. If the paging message contains the ID of the mobile phone, the mobile phone initiates a paging response. On subframe 4, if the mobile phone finds a P-RNTI, it will obtain a paging message from the PDSCH in the same subframe according to the radio resource location and MCS indicated by the PDCCH, and determine whether the paging message includes the wearable device ID . If the paging message contains the ID of the wearable device, the mobile phone forwards the paging message to the wearable device through 3GPP D2D, Bluetooth, Wi-Fi, or other protocols, or notifies the wearable device of paging.

For another example, suppose that the PF of the mobile phone and the wearable device are the same, which are both frame 1, and the PO of the mobile phone and the wearable device are also the same, which are both subframe 4. On subframe 4, if the mobile phone finds a P-RNTI, it will obtain the paging message from the PDSCH in the same subframe according to the radio resource location and MCS indicated by the PDCCH, and determine whether the paging message is from the mobile phone and the wearable device. Id. If the paging message contains the ID of the mobile phone, the mobile phone initiates a paging response; if the paging message contains the ID of the wearable device, the mobile phone forwards the paging message to the device via 3GPP D2D, Bluetooth, Wi-Fi, or other protocols Wear the device, or notify the wearable device of paging.

In other words, on the PO corresponding to only the mobile phone, the mobile phone only needs to determine whether it is paged; on the PO corresponding to only the wearable device, the mobile phone only needs to determine whether the wearable device is paged; on the mobile phone and the wearable device On the corresponding POs, the mobile phone needs to determine whether both the mobile phone and the wearable device are paged separately.

2) The mobile phone is connected and the mobile phone is not configured to measure GAP.

If the mobile phone is configured to measure GAP, the mobile phone needs to reserve a portion of time (may be referred to as measuring GAP time). During this period of time, the mobile phone may not send or receive any data, or may not receive paging messages, and only perform inter-frequency measuring. It should be noted that, in the embodiments of the present application, the mobile phone is configured to measure the GAP can also be understood as the mobile phone is configured to measure the GAP configuration, the mobile phone is configured to measure the GAP includes the mobile phone is configured to measure the GAP, and the mobile phone is configured to measure the GAP. If the mobile phone is not configured to measure GAP, the mobile phone can normally send and receive data or receive paging messages in the connected state without inter-frequency measurement. Therefore, when the mobile phone is connected and the mobile phone is not configured to measure GAP, the mobile phone can monitor the paging message for the wearable device to save power consumption of the wearable device. The mobile phone and the wearable device can be in the same cell, or the mobile phone and the wearable device can be in different cells, but the mobile phone can receive the paging message of the cell where the wearable device is located.

For example, when the EPC needs to reattach the mobile phone, and when the EPC needs to send data or signaling to the wearable device, the MME can send a paging message to the base station. After receiving the paging message, the base station pages the mobile phone by sending a paging message at the PO of the mobile phone, and pages the wearable device by sending the paging message at the PO of the wearable device. A mobile phone in a connected state and not configured to measure GAP can receive a paging message sent by a base station at the PO of the mobile phone, and determine whether the paging message includes the ID of the mobile phone. If the paging message contains the ID of the mobile phone, the mobile phone initiates a paging response. A mobile phone in a connected state and not configured to measure GAP can also monitor the paging message of the wearable device on the PO of the wearable device, and determine whether the paging message includes the ID of the wearable device. If the paging message contains the ID of the wearable device, the mobile phone forwards the page to the wearable device through 3GPP D2D, Bluetooth, Wi-Fi, or other protocols, or informs the wearable device that there is a page.

Optionally, if the mobile phone monitors the paging message for the wearable device in the connected state, after the mobile phone releases the RRC connection, the mobile phone may continue to monitor the paging message for the wearable device.

3) The mobile phone is configured to measure GAP, and the measured GAP of the mobile phone does not coincide with part of the PO of the wearable device, or the measured GAP of the mobile phone does not coincide with all of the PO of the wearable device.

If the mobile phone is configured to measure GAP, the mobile phone needs to reserve a portion of time (may be called the GAP time measurement). During this period of time, the mobile phone may not send or receive any data, or may not receive paging messages, and only perform inter-frequency measuring. Therefore, when the measurement GAP of the mobile phone coincides with part of the PO of the wearable device, because the mobile phone needs to perform inter-frequency measurement on the part of the PO, the mobile phone does not monitor the paging message for the wearable device on the part of the PO, but can On the PO that does not coincide with the measurement GAP of the mobile phone, the wearable device monitors the paging message to save power consumption of the wearable device. When the measurement GAP of the mobile phone coincides with all POs of the wearable device, since the mobile phone needs to perform inter-frequency measurement on all POs of the wearable device, the mobile phone does not monitor paging messages for the wearable device on the PO of any wearable device . When the measurement GAP of the mobile phone does not coincide with all the POs of the wearable device, the mobile phone does not need to occupy the PO of the wearable device for inter-frequency measurement, so the mobile phone can monitor the paging message for the wearable device on all POs of the wearable device, To save power consumption of wearable devices. The mobile phone and the wearable device can be in the same cell, or the mobile phone and the wearable device can be in different cells, but the mobile phone can receive the paging message of the cell where the wearable device is located.

That is to say, if the mobile phone is configured to measure GAP, the mobile phone monitors the paging message for the wearable device at the non-coincident PO. The non-coincident PO is the PO of the wearable device that does not coincide with the measurement GAP of the mobile phone. The non-coincident PO may include part of the PO of the wearable device, or the non-coincident PO may include the entire PO of the wearable device. The mobile phone can first determine the PO of the wearable device that does not coincide with the measurement GAP of the mobile phone, and the mobile phone can monitor the paging message for the wearable device at the non-coincident PO.

For example, assuming that the mobile phone and the wearable device are in the same cell, when the cell system information changes, the base station can send a paging message on the PO of the mobile phone to page the mobile phone, and send a search on the PO of the wearable device The paging message pages the wearable device. A mobile phone configured to measure GAP can monitor its own paging message on its own PO (if the mobile phone's PO conflicts with the mobile phone's measurement GAP, the mobile phone does not monitor the paging message on the conflicting PO), if the paging message contains this Mobile phone ID, the mobile phone initiates a paging response. The mobile phone can also listen to the paging message of the wearable device on the PO of the wearable device that does not coincide with the measurement GAP of the mobile phone. If the paging message contains the ID of the wearable device, the mobile phone passes 3GPP D2D, Bluetooth, Wi-Fi. Fi or other protocols forward the page to the wearable device, or notify the wearable device that there is a page.

Optionally, if the mobile phone monitors the paging for the wearable device before the GAP measurement is configured, the mobile phone can monitor the paging message for the wearable device at the non-coincident PO after the mobile phone measures the GAP is configured.

In a possible design, if the mobile phone is configured to measure GAP, the mobile phone determines that the non-coincident POs are listening for paging messages for the wearable device, and the mobile phone sends the first information to the wearable device. The first information is used to indicate that the mobile phone is not in use The coincident PO is that the wearable device monitors the paging message. Among them, the non-coincident POs are the POs of the wearable device that do not coincide with the measurement GAP of the mobile phone. The mobile phone can send the first information to the wearable device through communication protocols such as 3GPP D2D, Bluetooth, Wi-Fi and the like.

Optionally, the mobile phone may determine the non-coincident PO according to the measurement GAP configuration parameter of the mobile phone and the configuration parameter of the PO of the wearable device. Optionally, the mobile phone may receive the configuration parameters of the wearable device's PO from the wearable device.

For example, if the mobile phone determines that the PF and PO of the wearable device include subframe 4 of frame 31, subframe 4 of frame 63, according to the configuration parameters of the PO of the wearable device, (n*32) -1) Subframe 4 of frame number 1, where n is an integer greater than or equal to 1. The mobile phone determines that the measured GAP of the mobile phone includes subframe 4 of frame 31 and subframe 4 of frame 63 according to the measured GAP configuration parameters of the mobile phone; then the POs that do not overlap include the subframe of (m*32-1) Frame 4, where m is an integer greater than or equal to 3. That is, the mobile phone can monitor the paging message for the wearable device in subframe 4 of frame (m*32-1).

In a possible design, when the mobile phone is configured with a measurement interval, and when the mobile phone is in an idle state, the mobile phone sends the first information to the wearable device. Or, when the mobile phone is configured with a measurement interval, and when the mobile phone is in an inactive state, the mobile phone sends the first information to the wearable device. Wherein, the measurement interval of the mobile phone may not coincide with part of the PO of the wearable device, or the measurement interval of the mobile phone may coincide with part of the PO of the wearable device.

802. The second device receives the first information sent by the first device.

The wearable device can receive the first information sent by the mobile phone through 3GPP D2D, Bluetooth, Wi-Fi and other communication protocols.

803. The first device monitors the paging message for the second device.

The mobile phone can wake up on its own PO to monitor its own paging message, and can wake up on the PO of the wearable device to monitor the paging message of the wearable device, and can sleep at other times, thereby reducing power consumption.

In a possible design, the mobile phone can listen to the paging message of the wearable device on all POs of the wearable device.

In a possible design, the mobile phone may listen to the paging message of the wearable device at the non-coincident PO. The non-coincident PO is the PO of the wearable device that does not coincide with the measured GAP of the first device.

804. The second device does not monitor the paging message of the second device.

In a possible design, after receiving the first information, the wearable device does not monitor the paging message of the wearable device on all POs of the wearable device. In this way, the wearable device does not need to wake up to monitor the paging message at the corresponding PO, which can save power consumption of the wearable device.

In a possible design, after receiving the first information, the wearable device does not monitor the paging message of the wearable device in the non-coincident PO. The non-coincident PO is the measurement GAP of the wearable device and the first device. POs that do not coincide.

Optionally, if the mobile phone is configured to measure GAP, and the measured GAP of the mobile phone coincides with a part of the PO of the wearable device (that is, there is a non-coincident PO), or if the first information is used to indicate that the first device is in the non-coincident PO When the second device monitors the paging message, the wearable device does not monitor the paging message of the wearable device in the non-coincident PO after receiving the first information.

For example, if the mobile phone determines that the PF and PO of the wearable device include subframe 4 of frame 31, subframe 4 of frame 63, according to the configuration parameters of the PO of the wearable device, the (n *32-1) Subframe 4 of frame number, where n is an integer greater than or equal to 1. The mobile phone determines that the measured GAP of the mobile phone includes subframe 4 of frame 31 and subframe 4 of frame 63 according to the measured GAP configuration parameters of the mobile phone; then the POs that do not overlap include the subframe of (m*32-1) Frame 4, where m is an integer greater than or equal to 3. That is, the wearable device may not monitor the paging message in subframe 4 of frame (m*32-1).

The method for determining the coincident PO and/or non-overlapping PO by the wearable device includes the following ways:

Method 1: The wearable device receives the third information sent by the mobile phone. The third information includes the measured GAP configuration parameter or the measured GAP configuration index of the mobile phone. The measured GAP configuration index has a corresponding relationship with the measured GAP configuration parameter. The wearable device determines the coincident PO and/or non-overlapping PO based on the third information. Specifically, the wearable device determines the coincident PO and/or the non-coincident PO according to the third information and the configuration parameter of the wearable device's PO.

Optionally, the wearable device may also notify the mobile phone of coincident POs and/or non-overlapped POs.

Method 2: The wearable device receives the fourth information sent by the mobile phone. The fourth information is used to indicate the coincident PO. The coincident PO is determined by the (mobile phone) according to the measurement GAP configuration parameters of the mobile phone and the configuration parameters of the wearable device PO. Optionally, the mobile phone may receive the configuration parameters of the wearable device's PO from the wearable device.

In a possible design, the fourth information includes at least one of the following parameters: the period, offset, and number of consecutive POs that overlap. In a period of overlapping POs, the continuous number of overlapping POs is the number of overlapping POs in a cycle. As shown in FIG. 9a, it is a schematic diagram (pattern) of a period of overlapping PO. Each box represents the PO of the wearable device, the shaded boxes are coincident POs, and the unshaded boxes are non-coincident POs. Each period of overlapping POs includes 4 POs, and each period includes 2 consecutive POs that overlap, that is, the number of consecutive POs that overlaps is 2. It should be noted that the unit of the cycle may be absolute time, such as milliseconds, seconds, etc., or subframes, frames, etc., or the number of POs of the wearable device, which is not limited in this application.

The offset of the coincident PO can be the offset of the coincident PO (for example, the first coincident PO in each cycle) relative to a certain system frame (for example, system frame 0 (SFN) 0), or it can be relative Due to the offset of the first PO of the wearable device, the first PO may be the PO with the smallest system frame number where all POs of the wearable device are located (it may also be understood as the first PO after the start of system frame 0 ), the first PO may also be the first PO after the start of a certain system frame. The unit of offset can be absolute time, such as milliseconds, seconds, etc., or subframes, frames, etc., or the period of the PO of the wearable device, or the number of POs of the wearable device, which is not limited in this application .

In a possible design, the start position of the period of the coincident PO can be determined according to the offset of the coincident PO. For example, suppose that the offset of the coincident PO is the offset relative to the first PO of the wearable device. If the offset is 2 (that is, the offset is 2 POs), the starting position of the period of the coincident PO is wearing The offset of the first PO of the device plus 2 POs is the third PO.

In another possible design, the starting position of the period of coincident PO may be determined according to the offset of the coincident PO and the period of coincident PO. For example, when the offset of the overlapping PO is an offset from the system frame 0 (SFN) 0, the starting frame number X of the period of the overlapping PO can be calculated according to equation (5), and can be calculated according to equation (6) The starting subframe number Y of the period of the coincident PO is calculated:

Xmod T=Floor(Offset/10) (5)

Y = Offset mod 10 (6)

Where T is the period of coincident PO; X represents the start frame number of the coincident PO period, Y represents the start subframe number of the coincident PO period; Offset represents the offset of the coincident PO; mod represents the remainder Operation; Floor represents rounding down operation.

Method 3: The wearable device receives the fifth information sent by the mobile phone. The fifth information is used to indicate the non-coincident PO. The non-coincident PO is determined by the mobile phone's measurement GAP configuration parameters and the wearable device's PO configuration parameters. of. The fifth information includes at least one of the following parameters: the period, offset, and number of consecutive POs that do not overlap. For the periods, offsets and consecutive numbers of non-coincident POs, reference may be made to the related descriptions of the periods, offsets and consecutive numbers of coincident POs, which will not be repeated here.

It should be noted that Mode 2 and Mode 3 can be performed in combination or separately, and this application is not limited.

805. If the first device meets the second condition, the first device sends second information to the second device.

In a possible design, if the mobile phone can satisfy the second condition without satisfying the first condition, the mobile phone may send second information to the wearable device, and the second information is used to indicate that the mobile phone is not a wearable device Listen for paging messages.

Among them, the second condition includes any of the following situations:

1) The mobile phone is in a connected state, and the mobile phone is not monitoring the paging message for the wearable device before being in the connected state.

If the mobile phone does not monitor paging for the wearable device in the idle state, the mobile phone does not monitor the paging message for the wearable device after establishing the RRC connection. In other words, the mobile phone only monitors its own paging message on its own PO. If the paging message contains the ID of the mobile phone, the mobile phone initiates a paging response. The mobile phone does not need to monitor the paging message of the wearable device on the PO of the wearable device.

2) The mobile phone is in an idle state, and the mobile phone does not monitor the paging message for the wearable device before being in the idle state.

If the mobile phone does not monitor the paging for the wearable device in the connected state, the mobile phone does not monitor the paging message for the wearable device after releasing the connection.

3) The mobile phone receives handover signaling or redirection signaling.

If the current serving cell cannot provide services for the mobile phone (for example, the wireless resources of the current serving cell deteriorate, or the mobile phone moves out of the current server cell), the mobile phone can perform handover or redirection. When the mobile phone is switched, it can always stay connected. The mobile phone can receive the handover signaling sent by the base station, switch to the target cell according to the handover signaling, and maintain the continuity of the user plane and the signaling plane on the target cell. When the mobile phone is redirected, it can return from the connected state to the idle state, and then re-initiate the access process according to the redirection signaling sent by the network device (for example, RRC connection release signaling carrying redirection information). The redirection information is used to instruct the mobile phone to redirect to a RAT different from the current radio access technology (radio access technology, RAT).

Since the service cell of the mobile phone and the wearable device after switching or redirection may be different, the mobile phone may not receive the paging message of the wearable device. Therefore, the mobile phone may no longer monitor the paging for the wearable device.

Optionally, if the mobile phone monitors paging for the wearable device before receiving the switching or redirection signaling, the mobile phone no longer monitors the paging message for the wearable device after the mobile phone receives the switching or redirection signaling.

Optionally, if the mobile phone does not monitor the paging for the wearable device before receiving the switching or redirection signaling, the mobile phone does not monitor the paging message for the wearable device after the mobile phone completes the switching or redirection.

4) Cell reselection occurs in the mobile phone.

If the service quality of the current serving cell is poor (for example, as the wireless resources of the current serving cell change, or the mobile phone moves, resulting in the signal quality of the serving cell being below a certain threshold), the mobile phone can be based on the serving cell and neighboring cells And the cell reselection criteria for cell reselection. The mobile phone can measure the signals of the serving cell and the neighboring cell. If a certain neighboring cell meets the cell reselection criteria, the mobile phone will select the cell for camping, that is, the cell is the new serving cell of the mobile phone. The cell reselection criterion may be that when the signal strength of a neighboring cell is greater than the sum of the signal strength of the current serving cell and a hysteresis, and it lasts for a certain time (reselection time), the mobile phone can select the neighboring cell to perform Resident.

After cell reselection occurs on the mobile phone, the service cell of the mobile phone and the wearable device may be different, and the mobile phone may not receive the paging message of the wearable device. Therefore, the mobile phone may no longer monitor the paging for the wearable device.

5). There is no service or limited service for mobile phones.

When the mobile phone has no service or limited service, since the mobile phone itself cannot receive the paging message, the paging message is no longer monitored for the wearable device.

6) The wireless link of the mobile phone fails.

After the wireless link of the mobile phone fails, the selection process of the serving cell needs to be performed. Since the mobile phone may select a service cell different from the service cell of the wearable device, the mobile phone may not receive the paging message of the wearable device. Therefore, the mobile phone may no longer monitor the paging message for the wearable device.

7) The RRC connection reconfiguration fails on the mobile phone.

After the RRC connection reconfiguration fails on the mobile phone, the serving cell selection process needs to be performed. Since the mobile phone may select a service cell that is different from the service cell of the wearable device, the mobile phone may not receive the paging message of the wearable device. Therefore, the mobile phone may no longer monitor paging for the wearable device.

8) The mobile phone is configured to measure GAP.

In other words, as long as the mobile phone is configured to measure GAP, the mobile phone does not monitor paging messages for the wearable device.

9) The mobile phone is configured to measure GAP, and the measurement GAP of the mobile phone coincides with part of the PO of the wearable device, or the measurement GAP of the mobile phone coincides with all of the PO of the wearable device, specifically including the following methods:

Method 1: If the measurement GAP of the mobile phone coincides with the PO of the wearable device, the mobile phone does not monitor the paging message for the wearable device. In other words, the mobile phone can first determine whether the measured GAP of the mobile phone coincides with the PO of the wearable device. If there is an overlap, the mobile phone does not monitor the paging message for the wearable device.

Optionally, in the case of method 1, if the mobile phone does not monitor paging for the wearable device before the GAP measurement is configured, after the mobile phone GAP is configured, if the measurement GAP of the mobile phone coincides with the PO of the wearable device , The mobile phone does not monitor the paging message for the wearable device. In other words, if the mobile phone does not monitor the paging for the wearable device before the measurement GAP is configured, the mobile phone needs to determine whether the PO of the wearable device coincides with the measurement GAP of the mobile phone after the measurement GAP is configured. Do not monitor paging messages for wearable devices.

Method 2: If the measured GAP of the mobile phone coincides with the PO of the wearable device, the PO of the mobile phone does not monitor the paging message for the wearable device. In other words, the mobile phone first determines whether the measurement GAP of the mobile phone coincides with the PO of the wearable device, and the PO where the mobile phone coincides does not monitor the paging message for the wearable device.

Optionally, in the case of method 2, if the mobile phone does not monitor paging for the wearable device before the GAP measurement is configured, after the mobile phone GAP is configured, if the measurement GAP of the mobile phone coincides with the PO of the wearable device , Then the phone's overlapping PO does not monitor the paging message for the wearable device. In other words, if the mobile phone does not monitor the paging for the wearable device before the measurement GAP is configured, the mobile phone needs to determine whether the measurement GAP of the mobile phone and the PO of the wearable device overlap after the measurement GAP is configured, if there is overlap ( PO), then the phone's overlapping PO does not monitor paging messages for the wearable device.

10) The mobile phone is configured to measure GAP, and the mobile phone does not monitor paging messages for the wearable device before the measurement GAP is configured.

Optionally, in the case of the above method 1 or method 2, if the mobile phone does not monitor the paging for the wearable device before the measurement of GAP is configured, the mobile phone does not monitor for the wearable device after the measurement of GAP is configured Call message. In other words, if the mobile phone does not monitor paging for the wearable device before the GAP measurement is configured, the mobile phone does not monitor for the wearable device regardless of whether the PO of the wearable device coincides with the measurement GAP of the mobile phone after the GAP measurement is configured Paging message. It can be understood that the mobile phone does not monitor the paging for the wearable device before the measurement of the GAP is configured, either because the service cell of the wearable device is different from the service cell of the mobile phone, or because the mobile phone is configured to measure the GAP (in this case (For reconfiguration) The measurement of the GAP on the front phone coincides with the PO of the wearable device, or it may be for other reasons, which is not limited in this application.

11) The measurement GAP of the mobile phone is released, and the mobile phone does not monitor the paging message for the wearable device before measuring the GAP release.

Optionally, in the case of the above method 1 or method 2, if the mobile phone does not monitor the paging for the wearable device before the measurement GAP configuration is released, the mobile phone does not monitor for the wearable device after the measurement GAP is released Paging message. It can be understood that the mobile phone does not monitor the paging for the wearable device before the measurement GAP is released. This may be because the measurement GAP of the mobile phone coincides with the PO of the wearable device, or it may be other reasons, which are not limited in this application.

In a possible design, if the mobile phone is configured to measure GAP, the mobile phone determines that the overlapping PO does not monitor the paging message for the wearable device, and the mobile phone sends second information to the wearable device, the second information is used to indicate that the mobile phone is overlapping Of PO does not monitor paging messages for wearable devices. The coincident PO is the PO that coincides with the measurement GAP of the mobile phone in the PO of the wearable device.

Optionally, the mobile phone may determine the coincident PO according to the measured GAP configuration parameters of the mobile phone and the configuration parameters of the PO of the wearable device. The configuration parameters of the PO of the wearable device may be sent to the mobile phone by the wearable device.

In a possible design, when the mobile phone configured with the measurement interval is in the connected state, and the mobile phone does not monitor the paging message for the wearable device before the connected state, the mobile phone may send the second information to the wearable device. Or, when the mobile phone configured with the measurement interval is in the idle state, and the mobile phone does not monitor the paging message for the wearable device before the idle state, the mobile phone may send the second information to the wearable device. Wherein, the measurement interval of the mobile phone may not coincide with part of the PO of the wearable device, or the measurement interval of the mobile phone may coincide with part of the PO of the wearable device.

806. The second device receives the second information sent by the first device.

The wearable device can receive the second information sent by the mobile phone through communication protocols such as 3GPP D2D, Bluetooth, and Wi-Fi.

807. The first device does not monitor the paging message for the second device.

The mobile phone can only wake up on its own PO to monitor its own paging messages, and can sleep at other times, thereby reducing power consumption.

808. The second device monitors the paging message of the second device.

In a possible design, after receiving the second information, the wearable device monitors the paging message of the wearable device on all POs of the wearable device.

In another possible design, after receiving the second information, the wearable device monitors the paging message of the wearable device in the coincident PO. The coincident PO is the same as the measured GAP of the first device in the wearable device PO. PO.

Optionally, if the mobile phone is configured to measure GAP, and the measured GAP of the mobile phone coincides with part of the PO of the wearable device, or if the second information is used to indicate that the first device is not monitoring paging for the second device at the overlapping PO Message, the wearable device listens to the paging message of the wearable device at the coincident PO after receiving the second information.

For the method for determining the coincident PO and/or non-overlapping PO by the wearable device, reference may be made to the relevant description of step 804, and no further description is provided here.

It should be noted that there is no inevitable execution sequence between steps 801 and 808, and this embodiment does not specifically limit the execution sequence between the steps.

With reference to the application scenarios and beneficial effects of the embodiments of the present application, taking the first device as a mobile phone and the second device as a smart watch as an example, the method for monitoring a paging message provided by the embodiment of the present application will be introduced.

As shown in FIG. 9b, assuming that both the mobile phone and the smart watch are in an idle state, the mobile phone and the smart watch can monitor the paging message sent by the base station on their corresponding PF and PO respectively according to their corresponding DRX cycles. Because the battery life of the smart watch is short and the power consumption is fast, it may quickly run out and cause an automatic shutdown. At this time, in order to save power consumption of the smart watch, the mobile phone can be used to monitor the paging message instead of the smart watch. Users can pair their mobile phones and smart watches with Bluetooth, or connect to the same Wi-Fi, or switch to 3GPP D2D mode. The mobile phone determines whether the first condition is met (see related description above). If it is satisfied, as shown in FIG. 9c, the mobile phone can send the first information to the smart watch via Bluetooth, Wi-Fi or 3GPP D2D, the first information is used to indicate The mobile phone monitors the paging message for the smart watch. After receiving the first message, the smart watch may not monitor paging messages on its PF and PO to save power consumption. As shown in Figure 9d, if the mobile phone receives the paging message of the smart watch (that is, the paging message of the smart watch is received on the PDSCH), the mobile phone can send the smart watch search to the smart watch through Bluetooth, Wi-Fi, or 3GPP D2D Call message. The smart watch can be processed according to the paging message sent by the mobile phone. For example, if the paging ID carried in the paging message is S-TMSI (where TMSI is temporary mobile subscriber identity, and S represents that the TMSI is assigned by MME), it means that this paging is a For normal business calls, the smart watch can establish an RRC connection with the base station. If the paging ID is an international mobile subscriber identification number (IMSI), it means that this paging is an abnormal call and is used for error recovery on the network side. In this case, the smart watch needs to be attached again. (attch) process. If the received paging message carries a system message change indicator, it means that the system message will start to change in the next modification cycle. In this case, the smart watch needs to re-read the system information block 1 (system information block 1, SIB1), obtain the systemInfoValueTag in SIB1, and then compare whether the SIB identification value read this time is the same as the last read. If they are different, it just means that the system message has changed. At this time, it is necessary to re-read these system messages according to the scheduling information in SIB1.

Based on the method provided in the embodiment of the present application, if the first device meets the first condition, the first device sends first information to the second device, and the first information is used to instruct the first device to monitor the paging message for the second device. Therefore, when the first device monitors the paging message for the second device, the second device does not need to monitor the paging message, which can reduce the power consumption of the second device (such as a wearable device).
