Description

Paging method, device, terminal, network side equipment and storage medium

Technical Field

The present application belongs to the field of communication technology, and specifically relates to a paging method, apparatus, terminal, network-side equipment and storage medium.

Background technique

In the fifth generation ( ^5th Generation, 5G) communication system, the mechanism for user equipment (UE) to monitor paging is as follows: UE first monitors the paging occasion (PO) corresponding to its own terminal identification UE ID. If it monitors the physical downlink control channel (PDCCH) scrambled by the paging radio network temporary identification (P-RNTI), and the PDCCH indicates the time-frequency resource information of the physical downlink shared channel (PDSCH), the UE continues to receive the corresponding PDSCH. If a UE identification ID carried in the Paging message carried in the PDSCH matches its own ID, the UE confirms that it has been paged.

In the network, multiple UE IDs correspond to one PO; that is, multiple UEs monitor PDCCH at the same PO. If one of the N UEs monitoring the same PO is paged, all N UEs need to receive PDCCH and PDSCH. When only a small number of UEs are paged in a PO, non-paging target UEs also need to receive PDSCH, resulting in unnecessary power consumption of non-paging target UEs.

Summary of the invention

It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

The following is an introduction to the relevant technologies involved in this application.

Paging mechanism: The network can send paging to UEs in idle or inactive states. The paging process can be used to notify a UE to receive paging requests and/or notify system information updates, as well as to notify UE to receive information such as the Earthquake and Tsunami Warning System (ETWS) and the Commercial Mobile Alert Service (CMAS).

For each UE, a paging time PO needs to be detected in a discontinuous reception (DRX) cycle. The UE calculates its corresponding paging frame and paging time based on the UE ID, DRX cycle, and the network's configuration information about paging. When paging is to transmit a paging request to a certain UE, the PO contains the Paging PDCCH, where the paging PDCCH indicates the time-frequency resource location of the PDSCH; when paging is to notify system information updates or public emergency notifications, only the Paging PDCCH needs to be received.

A UE in the RRC idle (RRC_IDLE) state or the RRC inactive (RRC_INACTIVE) state performs PDCCH detection on its corresponding PO in each DRX cycle, and first determines whether the PO carries a PDCCH encrypted with P-RNTI, and then determines whether the paging is for sending a paging message and/or system information update and/or ETWS/CMAS notification; if it is for sending a paging message, the UE continues to receive the PDSCH and determines from the received PDSCH whether it carries its own UE ID.

The UE uses the short message indicator and the short message on the DCI format 1_0 scrambled by the P-RNTI to indicate the system information change and/or ETWS/CMAS notification and/or PDSCH scheduling information.

Among them, DCI format 1_0 uses 2 bits to represent Short Message Indicator. The specific meaning is shown in Table 1.

Table 1 Short Message indicator

Bit Domain Short Message indicator 00 reserve 01 The DCI contains only scheduling information for paging. 10 Only short messages exist in DCI 11 DCI contains both scheduling information and short messages for paging.

In DCI format 1_0, 8 bits are used to represent Short Message. The specific meaning is shown in Table 2.

Table 2 Short Message

If the UE parses the PDCCH carrying P-RNTI on the PO and the Short Message indicator indicates 01 or 11, the UE receives the PDSCH according to the scheduling information of the PDSCH indicated on the PDCCH; the paging message (data on the PDSCH) received by the UE contains a list of UE IDs of the paging UEs. The terminal needs to use its own UE ID to match the UE ID carried in the paging message to determine whether the paging message is sent to itself.

If the UE parses the PDCCH carrying the P-RNTI on the PO, and the Short Message indicator indicates 10 and only systemInfoModification is set to 1 in the Short Messages, the UE still needs to check the SI change indication on its corresponding PO in each DRX cycle before the modification period boundaries. Until the next modification period boundaries, the UE re-acquires the new system information.

If the UE parses the PDCCH carrying the P-RNTI on the PO, and the Short Message indicator indicates 10 and only etwsAndCmasIndication is set to 1 in the Short Messages, the UE immediately obtains the new system information.

If the UE does not parse the PDCCH carrying the P-RNTI on the PO, it does not need to receive the PDSCH and can enter sleep mode according to the DRX cycle. With this mechanism, within a DRX cycle, the UE can only receive the PDCCH at the time when the PO appears, and then receive the PDSCH as needed. It can sleep at other times to save power.

In order to avoid UE from frequently monitoring paging, the protocol stipulates that UE only needs to monitor paging once in a DRX cycle. Assume that the NW configures the UE's DRX cycle to be 2.56s. In each radio frame with a length of 10ms, the network configures 4 POs. Then, in the UE's DRX cycle, there are a total of 256*4=1024 POs.

The UE selects which PO it should monitor paging at based on the last 10 bits of its paging ID (which can indicate 1024 PO positions).

In the network, multiple UE IDs correspond to one PO; that is, multiple UEs monitor PDCCH at the same PO. If one of the N UEs monitoring the same PO is paged, all N UEs need to receive PDCCH and PDSCH. When only a small number of UEs are paged in a PO, non-paging target UEs also need to receive PDSCH, resulting in unnecessary power consumption of non-paging target UEs.

In order to solve the above problems, the embodiments of the present application provide a paging method. The paging method provided by the embodiments of the present application is described in detail below through some embodiments and application scenarios in conjunction with the accompanying drawings.

FIG. 2 is a flow chart of a paging method according to an embodiment of the present application. As shown in FIG. 2 , the method includes:

Step 200: The terminal receives first configuration information;

The first configuration information includes at least one of the following:

A first paging identity corresponding to the terminal or auxiliary information used to obtain the first paging identity;

The applicable location range of the first paging identifier.

Optionally, the terminal receives a configuration message from the network, and the configuration message may be an RRC message such as RRCRelease or RRCReconfiguration. The embodiment of the present application does not limit the RRC message used; the configuration carried in the RRC message, i.e., the first configuration information, includes at least one of the following: a first paging identifier corresponding to the terminal; auxiliary information for obtaining the first paging identifier; an applicable location range of the first paging identifier, such as a cell identifier list cell IDlist: cell1, cell2;

It should be noted that the first paging identifier is shorter than the paging identifier used by the corresponding paging mechanism in 3GPP NR R15.

The paging identifier used by the corresponding paging mechanism in 3GPP NR R15 is 5G-S-TMSI, with a length of 48 bits, <5G-S-TMSI> = <AMF Set ID><AMF Pointer><5G-TMSI>, arranged from high to low as follows: Access and Mobility Management Function (AMF) Set ID: 10 bits long; AMFPointer: 6 bits long; 5G temporary mobile subscriber identity (5G-TMSI): 32 bits long.

For the sake of ease of description, in the embodiments of the present application, the paging identifier used by the corresponding paging mechanism in 3GPP NR R15 is referred to as the legacy UE ID.

Since the first paging identifier is shorter than the legacy UE ID, the uniqueness of the first paging identifier corresponding to each terminal can only be guaranteed within the location range to which the first paging identifier is applicable.

In some optional embodiments, the terminal receives first configuration information, where the first configuration information includes a first paging identifier corresponding to the terminal and an applicable location range corresponding to the first paging identifier.

Optionally, the applicable location range corresponding to the first paging identifier is represented by one of the following:

Cell identity or Tracking Area (TA identity, TAI) or RAN based Notification Area (RNA) identity;

Cell ID list cell ID list or TA ID list TAI list;

Mixed lists;

Optionally, the mixed list may be a list consisting of a cell identifier and a TA identifier, or a list consisting of a TA identifier and an RNA identifier.

Optionally, the RNA identifier may be embodied as a TAI list or a cell ID list.

Step 201: Based on the first configuration information, detect the physical downlink control channel PDCCH to determine whether it is paged;

Optionally, the terminal detects the PDCCH within the paging time PO based on the first configuration information, and determines whether it is paged according to the detection result.

Optionally, the PDCCH carries a first paging identifier.

In some embodiments, the PDCCH may be a P-RNTI-scrambled PDCCH, and the P-RNTI-scrambled PDCCH carries the first paging identifier or the first paging identifier list of the paged terminal.

In some embodiments, the PDCCH may be a PDCCH scrambled by applying the first paging identifier of the paging terminal. Wherein, applying the first paging identifier of the paging terminal may be using only the first paging identifier of the paging terminal, or using the first paging identifier of the paging terminal and other identifiers, which can be understood as the PDCCH being scrambled by applying an identifier including the first paging identifier of the paging terminal.

Optionally, the PDCCH does not carry the first paging identifier of the paged terminal, but carries the time-frequency resource information of the PDSCH, and the terminal receives the paging message based on the legacy UE ID. That is, the PDSCH is received according to the time-frequency resource information of the PDSCH, and whether the legacy UE ID of the paged terminal carried in the paging message carried by the PDSCH matches the legacy UE ID of the terminal itself is determined.

Among them, when at least one of the following conditions is met, the PDCCH does not carry the first paging identifier of the paged terminal: at least one terminal does not support the reception of paging messages based on the first paging identifier; the number of terminals that the network needs to page is greater than a preset threshold; the network does not support/has not enabled the function of paging based on the first paging identifier.

It is understandable that if the terminal determines that it has not been paged after receiving the PDCCH, it does not need to receive the PDSCH.

In an embodiment of the present application, the terminal detects the physical downlink control channel PDCCH according to the first configuration information, and can determine whether it is paged based on the detection result. When only a small number of UEs are paged in a PO, unnecessary power consumption caused by the terminal decoding PDSCH can be avoided, thereby achieving terminal energy saving.

In some optional embodiments, the detecting a physical downlink control channel PDCCH based on the first configuration information to determine whether it is paged includes:

If, within the applicable position range of the first paging identifier, a PDCCH scrambled by a paging radio network temporary identifier P-RNTI is detected within the paging time PO corresponding to the terminal, and it is determined that the PDCCH carries the first paging identifier, the first paging identifier corresponding to the terminal is matched with the first paging identifier carried by the PDCCH;

When the first paging identifier corresponding to the terminal successfully matches a first paging identifier carried by the PDCCH, the terminal determines that it is paged; or,

In the case that the first paging identifier corresponding to the terminal fails to match with all the first paging identifiers carried by the PDCCH, the terminal determines that it is not paged.

Optionally, the first paging identifier carried by the PDCCH includes the first paging identifiers of all paging terminals.

If the terminal is within the applicable position range of the first paging identifier and detects a PDCCH encrypted with P-RNTI in the PO corresponding to the terminal, the terminal matches its corresponding first paging identifier with the first paging identifier carried by the PDCCH. If the first paging identifier corresponding to the terminal is consistent with a first paging identifier of a paged terminal carried by the PDCCH, it can be understood that the first paging identifier corresponding to the terminal is successfully matched with a first paging identifier carried by the PDCCH, and the terminal determines that it is paged.

Optionally, if the first paging identifier of the paged terminal carried by the PDCCH does not contain an identifier consistent with the first paging identifier corresponding to the terminal, it can be understood that the first paging identifier corresponding to the terminal fails to match all first paging identifiers carried by the PDCCH, and the terminal determines that it is not paged.

Optionally, the determining that the PDCCH carries the first paging identifier includes one of the following:

Determining, according to content of the PDCCH, that the PDCCH carries a first paging identifier;

According to the format of downlink control information (Downlink Control Information, DCI) carried by the PDCCH, it is determined that the PDCCH carries a first paging identifier.

Optionally, when the existing DCI format 1_0 is multiplexed, the UE determines, according to the content of the PDCCH, that the PDCCH carries the first paging identifier. For example, if the value of the Short Message indicator is 00, it indicates that the PDCCH carries the first paging identifier.

Optionally, a new DCI format is defined, and the terminal determines, according to the format of the DCI carried by the PDCCH, that the PDCCH carries the first paging identifier.

In an embodiment of the present application, when PDCCH carries the first paging identifier, it does not carry the time-frequency resource information of PDSCH. Therefore, the terminal that is not paged does not need to receive PDSCH, thereby avoiding unnecessary power consumption caused by the terminal decoding PDSCH, achieving energy saving, and because PDCCH carries the first paging identifier, it can reduce network overhead.

In some optional embodiments, the detecting a physical downlink control channel PDCCH based on the first configuration information to determine whether it is paged includes:

If, within the applicable position range of the first paging identifier, a PDCCH scrambled by the first paging identifier corresponding to the terminal is detected within the paging time PO corresponding to the terminal, the terminal determines that it is paged; or,

If no PDCCH scrambled by the first paging identifier corresponding to the terminal is detected within the paging time instant PO corresponding to the terminal, the terminal determines that it is not paged.

It can be understood that the PDCCH sent by the network may be a PDCCH scrambled by an identifier including the first paging identifier of the paging terminal.

If a PDCCH scrambled using the first paging identifier corresponding to the terminal is detected within the applicable position range of the first paging identifier and within the paging time PO corresponding to the terminal, that is, if the terminal detects the PDCCH and decodes the PDCCH using the first paging identifier corresponding to the terminal and the decoding is successful, the terminal is determined to be paged.

No PDCCH scrambled with the first paging identifier corresponding to the terminal is detected within the paging time PO corresponding to the terminal, that is, if the terminal detects the PDCCH and decodes the PDCCH with the first paging identifier corresponding to the terminal and the decoding fails, the terminal determines that it is not paged.

In an embodiment of the present application, the terminal determines whether it is paged by decoding the detected PDCCH using its corresponding first paging identifier. A terminal that is not paged does not need to receive PDSCH, thereby avoiding unnecessary power consumption caused by the terminal decoding PDSCH, achieving terminal energy saving, and because PDCCH does not need to carry PDSCH scheduling information, network overhead can be reduced.

Optionally, detecting a physical downlink control channel PDCCH to determine whether it is paged includes:

If the PDCCH is detected within the applicable position range of the first paging identifier and within the paging time PO corresponding to the terminal, and it is determined that the PDCCH does not carry the first paging identifier, a paging message is received according to the second paging identifier corresponding to the terminal.

Among them, the second paging identifier is the paging identifier adopted by the corresponding paging mechanism in 3GPP NR R15. The paging identifier adopted by the corresponding paging mechanism in 3GPP NR R15 has been described in the previous embodiment and will not be repeated here.

If it is determined according to the content of the PDCCH or the DCI format that the PDCCH does not carry the first paging identifier, the terminal receives the paging message according to the second paging identifier.

It can be understood that when the conditions for paging based on the first paging identifier cannot be met, for example, when at least one terminal does not support the reception of paging messages based on the first paging identifier, when the number of terminals that the network needs to page is greater than a preset threshold, and the network does not support or has not enabled the function of paging based on the first paging identifier, the embodiment of the present application supports paging based on the paging identifier adopted by the corresponding paging mechanism in 3GPP NR R15.

Optionally, based on the above embodiment, the paging method further includes:

Obtain system information of the new resident cell;

If the system information of the new resident cell cannot match the applicable location range of the first paging identifier, performing at least one of the following:

Receiving a paging message according to a second paging identifier corresponding to the terminal;

Reporting to the network side device that the terminal has moved out of the applicable location range of the first paging identifier;

Receiving configuration information of a new first paging identifier sent by a network side device, and using the new first paging identifier to receive a paging message;

Release the configuration information of the original first paging identifier.

Optionally, when the cell where the terminal resides changes, the terminal obtains system information of the new cell where the terminal resides to determine whether the terminal has moved out of the applicable location range of its first paging identity.

The system information includes at least one of the following: a cell identifier, a tracking area TA identifier, and a notification area RNA identifier of a wireless access network.

If an identifier consistent with the system information of the new resident cell cannot be found in the applicable location range of the first paging identifier, it can be understood that the system information of the new resident cell cannot match the applicable location range of the first paging identifier, that is, the terminal has moved out of the applicable range of its first paging identifier, then the terminal can no longer continue to support paging based on the first paging identifier, and the terminal performs at least one of the following:

Receiving a paging message according to a second paging identifier corresponding to the terminal;

Reporting to the network side device that the terminal has moved out of the applicable location range of the first paging identifier;

Receiving configuration information of a new first paging identifier sent by a network side device, and using the new first paging identifier to receive a paging message;

Release the configuration information of the original first paging identifier.

For example, the terminal reports to the network side device that the terminal has moved out of the applicable location range of the first paging identifier. If the configuration information of the new first paging identifier sent by the network side device is received, the paging message is received using the new first paging identifier. Otherwise, the paging message is received according to the second paging identifier corresponding to the terminal.

Optionally, the terminal directly receives the paging message according to the second paging identifier corresponding to the terminal.

Optionally, after the terminal moves out of the applicable scope of its first paging identifier, it releases the configuration information of the original first paging identifier. The release operation may be performed based on an instruction of the network or automatically performed by the terminal.

The embodiment of the present application considers how to perform paging when the terminal moves out of the applicable location range of the first paging identifier.

Optionally, based on the above embodiment, the paging method further includes:

Report terminal capability indication information to a network side device, where the terminal capability indication information is used to indicate that the terminal supports paging based on the first paging identifier.

Optionally, when the terminal is capable of receiving a paging message based on the first paging identifier, the terminal may report terminal capability indication information to the network side device, where the terminal capability indication information is used to indicate that the terminal supports paging based on the first paging identifier.

Optionally, based on the above embodiment, the paging method further includes:

A first response message sent by a network side device is received, where the first response message is used to instruct the network side device to determine that the terminal capability indication information is received and/or to notify the terminal to enable a paging function based on a first paging identifier.

Optionally, the terminal receives a first response message sent by the network side device, where the first response message is used to indicate that the network side device determines that the terminal capability indication information is received, and/or to notify the terminal to enable a paging function based on a first paging identifier.

Optionally, after the terminal receives the first response message sent by the network side device, the terminal enables the paging function based on the first paging identifier, and the terminal attempts to receive the paging message based on the first paging identifier in the corresponding PO.

Optionally, based on the above embodiment, the paging method further includes:

Receive cell indication information sent by a network side device, where the cell indication information is used to indicate that the cell supports or enables a paging function based on a first paging identifier.

Optionally, the terminal receives a broadcast message sent by a network side device, where the broadcast message carries cell indication information, where the cell indication information is used to indicate that the cell supports or enables a paging function based on the first paging identifier.

After receiving the cell indication information, the terminal attempts to receive a paging message based on the first paging identifier in the corresponding PO.

Optionally, based on the above embodiment, the paging method further includes:

When the terminal moves out of the tracking area or the notification area of the radio access network, the location area update process is initiated, and a tracking area update TAU request or a notification area update RNAU request of the radio access network is sent to the network side device;

Receive a second response message sent by a network side device, wherein the second response message carries network indication information, and the network indication information is used to indicate that the cell corresponding to the tracking area identity (TA identity, TAI) or the TAI list or RNA supports or enables a paging function based on the first paging identity.

Optionally, when the terminal moves out of the TA or RNA, a Tracking Area Update (TAU) request or a RAN based Notification Area Update (RNAU) request is sent to the network side device.

The terminal receives a second response message sent by the network side device, and the second response message carries network indication information, and the network indication information is used to indicate that the cell corresponding to the TAI supports or enables the function of paging based on the first paging identifier, or indicates that the cell corresponding to the TAI list supports or enables the function of paging based on the first paging identifier, or indicates that the cell corresponding to the RNA supports or enables the function of paging based on the first paging identifier. After receiving the second response message, the terminal attempts to receive a paging message based on the first paging identifier in the corresponding PO.

Among them, the cell corresponding to TAI refers to the cell whose TAI-related parameters of the cell broadcast information are consistent with the TAI; the cell corresponding to the TAI list refers to the cell whose TAI-related parameters of the cell broadcast information are consistent with a TAI in the TAI list; the cell corresponding to RNA refers to the cell whose cell broadcast information matches the RNA configuration.

Optionally, when the first configuration information includes auxiliary information used to obtain the first paging identifier, the method further includes:

The terminal determines the first paging identifier corresponding to the terminal based on the auxiliary information used to obtain the first paging identifier.

For example, the auxiliary information indicates that the part other than the upper N bits and/or lower M bits of the legacy UE ID is the first paging identifier. The terminal determines the first paging identifier corresponding to the terminal based on the auxiliary information used to obtain the first paging identifier, and receives the paging message using the first paging identifier.

Optionally, the first paging identifier includes one of the following:

X bits in the second paging identifier, where X is a natural number greater than 1;

The remaining bits after removing the last Log ₂ N*Ns bits in the second paging identifier, where N is the number of paging frames in a discontinuous reception DRX cycle, and Ns is the number of paging time instants PO in a paging frame;

An identifier calculated based on a cell identifier, a TA identifier or an RNA identifier, and an offset value;

The identifier is calculated based on the cell identifier, the TA identifier or the RNA identifier, and the second paging identifier.

Optionally, the first paging identifier may be X bits in the second paging identifier, for example, X=10;

Optionally, the first paging identifier may be the remaining bits of the second paging identifier after removing the last Log ₂ N*Ns bits.

One principle is that the part of the second paging identifier that can be indicated by the PO position is no longer carried in the first paging identifier.

For example, assume that the DRX cycle of the UE is configured by the NW to be 1.28s (corresponding to T in 38.304). In each 10ms radio frame, the network configures 4 (corresponding to Ns in 38.304) POs. Then, in the DRX cycle of the UE, there are 128*4=512 POs in total.

The UE selects which PO it should monitor paging at based on the last 9 digits of its paging ID (which can indicate 512 PO positions).

Therefore, the last 9 digits of the legacy UE ID should not be carried in the short ID.

Optionally, the last Log ₂ (T/10ms)*Ns bits in the legacy UE ID should not be carried in the short ID.

Another formula expression: In 38.304, the UE-PO calculation formula is described, based on the parameters in the formula:

N is the number of total paging frames in T in a discontinuous reception DRX cycle, and Ns is the number of paging occasions for a PF in a paging frame.

Optionally, the last Log ₂ N*Ns bits in the legacy UE ID shall not be carried in the short ID.

In order to further shorten the legacy UE ID and obtain the first paging identifier, the first paging identifier may not carry some high-order bits, such as all or part of the bits of the AMF Set ID and/or AMF Pointer.

Optionally, the first paging identifier is calculated based on the cell identifier, the TA identifier or the RNA identifier, and the offset value;

Optionally, the first paging identifier is calculated based on the cell identifier, the TA identifier or the RNA identifier, and some bits or all bits of the second paging identifier.

In the embodiment of the present application, the first paging identifier is calculated by the network side device and the terminal according to the above method.

FIG3 is a second flow chart of a paging method provided in an embodiment of the present application. The execution subject of the method is a network side device, such as a base station. As shown in FIG3 , the method includes:

Step 300: The network side device sends first configuration information to the terminal;

The network side device sends a network configuration message to the terminal. The configuration message may be an RRC message such as RRC Release or RRCReconfiguration. The embodiment of the present application does not limit the RRC message used; the configuration carried in the RRC message is the first configuration information.

The first configuration information includes at least one of the following:

a first paging identifier corresponding to the terminal, or auxiliary information used to obtain the first paging identifier;

The applicable location range of the first paging identity is, for example, a cell identity list cell list: cell1, cell2.

It should be noted that the first paging identifier is shorter than the paging identifier used by the corresponding paging mechanism in 3GPP NR R15. 3GPP NR R15 has been described in the above embodiments and will not be repeated here.

For the sake of ease of description, in the embodiments of the present application, the paging identifier used by the corresponding paging mechanism in 3GPP NR R15 is referred to as the legacy UE ID.

Since the first paging identifier is shorter than the legacy UE ID, the uniqueness of the first paging identifier corresponding to each terminal can only be guaranteed within the location range to which the first paging identifier is applicable.

In some optional embodiments, the terminal receives first configuration information, where the first configuration information includes a first paging identifier corresponding to the terminal and an applicable location range corresponding to the first paging identifier.

Optionally, the applicable location range corresponding to the first paging identifier includes one of the following:

Cell or Tracking Area (TA) or RANbased Notification Area (RNA);

Cell list or TA list or RNA list;

Mixed lists;

Optionally, the mixed list may be a list consisting of cells and TAs, or a list consisting of TA regions and RNAs.

Step 301: Send a physical downlink control channel PDCCH;

The network side device sends a PDCCH, wherein the PDCCH carries the first paging identifier of the paged terminal or the time-frequency resource information of the physical downlink shared channel PDSCH.

In some embodiments, the PDCCH may be a P-RNTI scrambled PDCCH carrying the first paging identifier of the paged terminal. It is understandable that when there are multiple paged terminals, the PDCCH carries the first paging identifiers corresponding to all paged terminals.

In some embodiments, the PDCCH may be a PDCCH scrambled by applying the first paging identifier of the paging terminal. Wherein, applying the first paging identifier of the paging terminal may be using only the first paging identifier of the paging terminal, or using the first paging identifier of the paging terminal and other identifiers, which can be understood as the PDCCH being scrambled by applying an identifier including the first paging identifier of the paging terminal.

Optionally, the PDCCH does not carry the first paging identifier of the paged terminal, but carries the time-frequency resource information of the PDSCH, and the terminal receives the paging message based on the legacy UE ID. That is, the PDSCH is received according to the time-frequency resource information of the PDSCH, and whether the legacy UE ID of the paged terminal carried in the paging message carried by the PDSCH matches the legacy UE ID of the terminal itself is determined.

Among them, when at least one of the following conditions is met, the PDCCH does not carry the first paging identifier of the paged terminal: at least one terminal does not support the reception of paging messages based on the first paging identifier; the number of terminals that the network needs to page is greater than a preset threshold; the network does not support or has enabled the function of paging based on the first paging identifier.

In an embodiment of the present application, a network side device sends first configuration information to a terminal so that the terminal detects a physical downlink control channel PDCCH and determines whether it is paged based on the detection result. This can avoid unnecessary power consumption caused by the terminal decoding PDSCH when only a small number of UEs are paged in a PO, thereby achieving terminal energy saving. At the same time, when PDCCH carries the first paging identifier of the paged terminal, since there is no need to carry PDSCH resources, network overhead can be effectively reduced.

Optionally, the sending of a physical downlink control channel PDCCH includes one of the following:

When the number of paging terminals is less than a first preset threshold and all of them support or enable a paging function based on the first paging identifier, sending a PDCCH scrambled by a paging radio network temporary identifier P-RNTI, wherein the PDCCH scrambled by the P-RNTI carries the first paging identifier;

When the number of paging terminals is less than a first preset threshold and all support or enable a paging function based on a first paging identifier, scramble the PDCCH using the first paging identifier of the paging terminal, obtain the PDCCH scrambled by the first paging identifier, and send the PDCCH scrambled by the first paging identifier, wherein the PDCCH scrambled by the first paging identifier carries the first paging identifier;

When a preset condition is met, a PDCCH scrambled by a paging radio network temporary identifier P-RNTI is sent, where the PDCCH scrambled by the P-RNTI carries time-frequency resource information of the PDSCH;

The preset condition includes at least one of the following:

The number of paging terminals is greater than a second preset threshold;

At least one of the paging terminals does not support or has not enabled a function of performing paging based on the first paging identifier;

The network does not support or does not enable the paging function based on the first paging identifier.

The first preset threshold and the second preset threshold are preset.

Optionally, when the number of terminals is small and all support or have enabled the function of paging based on the first paging identifier, the network side device performs paging based on the first paging identifier, that is, sends a P-RNTI-scrambled PDCCH, which carries the first paging identifier of the paged terminal, or sends a PDCCH scrambled by the first paging identifier.

Optionally, when the number of terminals is large and/or at least one terminal does not support or has not enabled the function of paging based on the first paging identifier, the network side device performs paging based on the legacy UE ID, that is, sends a P-RNTI-scrambled PDCCH, the P-RNTI-scrambled PDCCH carries the time-frequency resource information of the PDSCH, and the data carried by the PDSCH carries the legacy UE ID of the paged terminal.

Optionally, when the network does not support or does not enable the function of performing paging based on the first paging identifier, paging is performed based on the legacy UE ID, which is compatible with the existing paging mechanism.

In an embodiment of the present application, when only a small number of UEs are paged in a PO of the PDCCH sent by the network side device to the terminal, the PDCCH carries the first paging identifier of the paged terminal, which can avoid unnecessary power consumption caused by the terminal decoding PDSCH and achieve terminal energy saving. At the same time, since there is no need to carry PDSCH resources, the network overhead can be effectively reduced; when the conditions for paging based on the first paging identifier cannot be met, the embodiment of the present application also supports paging based on the paging identifier adopted by the corresponding paging mechanism in 3GPP NR R15.

In some optional embodiments, before sending a physical downlink control channel PDCCH, the method further includes:

Terminal capability indication information reported by a terminal is received, where the terminal capability indication information is used to indicate that the terminal supports paging based on a first paging identifier.

Optionally, before sending the PDCCH, the network side device receives terminal capability indication information reported by the terminal, where the terminal capability indication information is used to indicate that the terminal supports paging based on the first paging identifier.

Based on the above embodiment, optionally, the method further includes:

A first response message is sent to the terminal, where the first response message is used to instruct the network side device to determine that the terminal capability indication information is received and/or to notify the terminal to enable a paging function based on the first paging identifier.

Optionally, the network side device sends a first response message to the terminal, and the first response message is used to indicate that the network side device determines that the terminal capability indication information is received and/or notifies the terminal to enable the function of paging based on the first paging identifier. Then, the network side device sends the first configuration information to the terminal so that the terminal attempts to receive the paging message based on the first paging identifier in the corresponding PO.

Optionally, the first paging identifier of the paged terminal carried by the PDCCH is indicated by one of the following:

Contents of PDCCH;

The format of the downlink control information DCI carried by PDCCH.

Optionally, when the existing DCI format 1_0 is reused, the PDCCH carries the first paging identifier of the paged terminal and indicates it through the content of the PDCCH, that is, the UE determines that the PDCCH carries the first paging identifier according to the content of the PDCCH. For example, if the Short Message indicator value is 00, it indicates that the PDCCH carries the first paging identifier.

Optionally, a new DCI format is defined, and the first paging identifier of the paged terminal carried by the PDCCH is indicated through the new DCI format. The terminal determines that the PDCCH carries the first paging identifier according to the format of the DCI carried by the PDCCH.

Optionally, also include:

A message sent by a receiving terminal indicating that the terminal has moved out of the applicable location range of the first paging identifier, and configuration information of a new first paging identifier is sent to the terminal.

Optionally, when the cell where the terminal resides changes and the terminal determines that it has moved out of the applicable location range of the first paging identifier, the terminal sends a message indicating that it has moved out of the applicable location range of the first paging identifier, the network side device receives the message sent by the terminal indicating that it has moved out of the applicable location range of the first paging identifier, configures a new first paging identifier for the terminal, and sends the configuration information of the new first paging identifier to the terminal.

Optionally, also include:

Cell indication information is sent to the terminal, where the cell indication information is used to indicate that the cell supports or enables a paging function based on the first paging identifier.

Optionally, the network side device sends a broadcast message, which carries cell indication information, that is, the cell supports or enables paging based on the first paging identification information.

Optionally, after receiving the cell indication information, the terminal attempts to receive a paging message based on the first paging identifier in the corresponding PO.

Optionally, also include:

Receiving a tracking area update TAU request sent by a terminal or a notification area update RNAU request sent by a radio access network;

A second response message is sent to the terminal, wherein the second response message carries network indication information, and the network indication information is used to indicate that the cell corresponding to the tracking area identifier TAI or the TAI list or RNA supports or enables the function of paging based on the first paging identifier.

Optionally, when the terminal moves out of the TA or RNA, a Tracking Area Update (TAU) request or a RAN based Notification Area Update (RNAU) request sent by the terminal is received by the network side device.

The network side device sends a second response message to the terminal, and the second response message carries network indication information, and the network indication information is used to indicate that the cell corresponding to the TAI supports or enables the function of paging based on the first paging identifier, or indicates that the cell corresponding to the TAI list supports or enables the function of paging based on the first paging identifier, or indicates that the cell corresponding to the RNA supports or enables the function of paging based on the first paging identifier. After receiving the second response message, the terminal attempts to receive a paging message based on the first paging identifier in the corresponding PO.

Among them, the cell corresponding to TAI refers to the cell whose TAI-related parameters of the cell broadcast information are consistent with the TAI; the cell corresponding to the TAI list refers to the cell whose TAI-related parameters of the cell broadcast information are consistent with a TAI in the TAI list; the cell corresponding to RNA refers to the cell whose cell broadcast information matches the RNA configuration.

Optionally, the first paging identifier includes one of the following:

X bits in the second paging identifier, where X is a natural number greater than 1;

The remaining bits after removing the last Log ₂ N*Ns bits in the second paging identifier, where N is the number of paging frames in a discontinuous reception DRX cycle, and Ns is the number of paging time instants PO in a paging frame;

An identifier calculated based on a cell identifier, a TA identifier or an RNA identifier, and an offset value;

The identifier is calculated based on the cell identifier, the TA identifier or the RNA identifier, and the second paging identifier.

Optionally, the first paging identifier may be X bits in the second paging identifier, for example, X=10;

Optionally, the first paging identifier may be the remaining bits of the second paging identifier after removing the last Log ₂ N*Ns bits.

One principle is that the part of the second paging identifier that can be indicated by the PO position is no longer carried in the first paging identifier.

For example, assume that the DRX cycle of the UE is configured by the NW to be 1.28s (corresponding to T in 38.304). In each 10ms radio frame, the network configures 4 (corresponding to Ns in 38.304) POs. Then, in the DRX cycle of the UE, there are 128*4=512 POs in total.

The UE selects which PO it should monitor paging at based on the last 9 digits of its paging ID (which can indicate 512 PO positions).

Therefore, the last 9 digits of the legacy UE ID should not be carried in the short ID.

Optionally, the last Log ₂ (T/10ms)*Ns bits in the legacy UE ID should not be carried in the short ID.

Another formula expression: In 38.304, the UE-PO calculation formula is described, based on the parameters in the formula:

N is the number of total paging frames in T in a discontinuous reception DRX cycle, and Ns is the number of paging occasions for a PF in a paging frame.

Optionally, the last Log ₂ N*Ns bits in the legacy UE ID shall not be carried in the short ID.

Optionally, the first paging identifier is calculated based on the cell identifier, the TA identifier or the RNA identifier, and the offset value;

Optionally, the first paging identifier is calculated based on the cell identifier, the TA identifier or the RNA identifier, and some bits or all bits of the second paging identifier.

At the same time, since there is no need to carry PDSCH resources, network overhead can be effectively reduced.
