In the fifth generation (5)^thGeneration, 5G) communication system, a mechanism for a User Equipment (UE) to monitor paging is as follows: UE firstly monitors the Paging Occasion (PO) corresponding to the UE ID of the terminal identification of the UE, and if the PO corresponding to the UE ID is monitored, the Paging radio network temporary identification (Paging) is monitored-Radio Network Temporary Identity, P-RNTI) scrambled Physical Downlink Control Channel (PDCCH), and the PDCCH indicates time-frequency resource information of a Physical Downlink Shared Channel (PDSCH), the UE continues to receive the corresponding PDSCH. And if the UE identification ID carried in the Paging message carried in the PDSCH is matched with the ID of the UE, the UE confirms that the UE is paged.

In the network, a plurality of UE IDs correspond to one PO; that is, multiple UEs may perform PDCCH monitoring at the same PO location. If one UE is paged among N UEs monitoring the same PO, all the N UEs need to receive the PDCCH and the PDSCH.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable.

Wherein, the terminal 11 may also be called a terminal Device or a User Equipment (UE), the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer) or a notebook Computer, a Personal Digital Assistant (PDA), a palmtop Computer, a netbook, a super-Mobile Personal Computer (UMPC), a Mobile Internet Device (MID), a Wearable Device (Wearable Device) or a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), and other terminal side devices, the Wearable Device includes: bracelets, earphones, glasses and the like.

The related art to which the present application relates is described below.

And (3) paging mechanism: the network may send a page to an idle-state, inactive-state UE, and the paging procedure may be used to notify a certain UE of receiving a paging request and/or notifying a system information update, and notify the UE of receiving information such as an Earthquake and Tsunami Warning System (ETWS) and a Commercial Mobile Alert Service (CMAS).

For each UE, one paging occasion PO needs to be detected in one Discontinuous Reception (DRX) cycle. And the UE calculates the paging frame and the paging time corresponding to the UE according to the UE ID, the DRX period and the paging configuration information of the network. When Paging is to transmit a Paging request to a certain UE, the PO comprises a Paging PDCCH, wherein the Paging PDCCH indicates a time-frequency resource position of a PDSCH; when Paging is for notifying system information update or common emergency notification, only the Paging PDCCH needs to be received.

The method comprises the steps that UE in an RRC IDLE (RRC _ IDLE) state or an RRC INACTIVE (RRC _ INACTIVE) state carries out PDCCH detection on a PO corresponding to the UE in each DRX period, firstly, whether the PO carries a PDCCH scrambled by a P-RNTI is judged, and then, whether paging is carried out is judged so as to send an indication paging message and/or system information update and/or an ETWS/CMAS notification; if the paging message is sent, the UE continues to receive the PDSCH and judges whether the UE ID of the UE is carried in the PDSCH from the received PDSCH.

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

In the DCI format 1_0, a Short Message Indicator is indicated by 2 bits, and specific meanings are shown in table 1.

TABLE 1 Short Message indicator

Bit field	Short Message indicator
		00	Retention
01	Only scheduling information for paging is present in DCI
		10	Only short message exists in DCI
11	Scheduling information and short message for paging simultaneously exist in DCI

In the DCI format 1_0, 8 bits are used for representing Short Message, and the specific meanings are shown in Table 2.

TABLE 2 Short Message

If the UE resolves the PDCCH carrying the 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 UE ID list of UEs with paging is included in the paging message (data on PDSCH) received by the UE, and the terminal needs to match the UE ID of itself with the UE ID included in the paging message to determine whether the paging message is sent to itself.

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

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

If the PDCCH carrying the P-RNTI is not analyzed on the PO by the UE, the UE can enter the dormancy according to the DRX period without receiving the PDSCH. With this mechanism, in one DRX cycle, the UE can receive the PDCCH only at the time position where the PO occurs, and then receive the PDSCH as needed. And can sleep at other times to achieve the purpose of saving power.

In order to avoid the UE frequently monitoring the paging, the protocol provides that the UE only needs to monitor the paging once in one DRX cycle. Assume that the NW configures the DRX cycle of the UE to be 2.56 s. The network is configured with 4 POs in each radio frame of length 10 ms. Then, there are a total of 256 × 4 — 1024 POs within the DRX cycle of the UE.

The UE selects which PO it should listen to the paging according to the last 10 bits of its paging ID (i.e. 1024 PO locations can be indicated).

In the network, a plurality of UE IDs correspond to one PO; that is, multiple UEs may perform PDCCH monitoring at the same PO location. If one UE is paged among N UEs monitoring the same PO, all the N UEs need to receive the PDCCH and the PDSCH, and when only a small number of UEs in one PO are paged, the non-paging target UE also needs to receive the PDSCH, thereby causing unnecessary power consumption of the non-paging target UE.

In order to solve the above problem, an embodiment of the present application provides a paging method. The paging method provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

Fig. 2 is a schematic flowchart of a paging method according to an embodiment of the present application, and as shown in fig. 2, the method includes:

step 200, the terminal receives first configuration information;

wherein the first configuration information comprises at least one of:

the applicable location range of the first paging identifier.

Optionally, the terminal receives a configuration message of the network, where the configuration message may be an RRC message such as RRCRelease or rrcreeconfiguration, and 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: a first paging identifier corresponding to the terminal; auxiliary information for acquiring the first paging identifier; the applicable location range of the first paging identifier, such as a cell identifier list cell ID list: cell1, cell 2;

it should be noted that the first paging identity is shorter than the paging identity used in the corresponding paging mechanism in 3GPP NR 15.

The paging identifier adopted by the corresponding paging mechanism in 3GPP NR R15 is 5G-S-TMSI, the length is 48 bits, <5G-S-TMSI > < AMF Set ID > < AMF Pointer > <5G-TMSI >, and the paging identifiers are arranged from high to low in order as Access and Mobility Management Function (AMF) Set IDs: the length is 10 bits; AMF Pointer: the length is 6 bits; 5G temporary Mobile subscriber identity (5G temporal mobile subscriber identity, 5G-TMSI): the length is 32 bits.

For convenience of description, in the embodiment of the present application, a paging identifier adopted by a corresponding paging mechanism in the 3GPP NR R15 is referred to as a legacy UE ID.

Because 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:

a cell (cell) identifier or a Tracking Area (TA) identifier (TA identity, TAI) or a radio access network (RAN based Notification Area, RNA) identifier;

A cell identification list cell ID list or a TA identification list TAI list;

a mixing list;

alternatively, the mixed list may be a list of cell identifiers and TA identifiers, or a list of TA identifiers and RNA identifiers.

Alternatively, the RNA identification may be embodied as a TAI list or a cell ID list.

Step 201, detecting a Physical Downlink Control Channel (PDCCH) based on the first configuration information, and determining whether to be paged;

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

Optionally, the PDCCH carries a first paging identifier.

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

In some embodiments, the PDCCH may be a PDCCH that applies the first paging identity scrambling of the paged terminal. Wherein, the first paging identifier applied to the paged terminal may be the first paging identifier only used for the paged terminal, or the first paging identifier and other identifiers used for the paged terminal, it may be understood that the PDCCH is a PDCCH scrambled with the identifier including the first paging identifier of the paged terminal.

Optionally, the PDCCH does not carry the first paging identifier of the paged terminal, but carries 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 paging message carried by the PDSCH is matched with the legacy UE ID of the paged terminal is determined.

Wherein, when at least one of the following conditions is satisfied, the PDCCH does not carry the first paging identifier of the paged terminal: at least one terminal does not support receiving paging messages based on the first paging identifier; the number of terminals to be paged by the network is greater than a preset threshold value; the network does not support/activate the function of paging based on the first paging identity.

It can be understood that if the terminal determines that the terminal is not paged after receiving the PDCCH, the terminal does not need to receive the PDSCH.

In the embodiment of the application, the terminal detects the Physical Downlink Control Channel (PDCCH) according to the first configuration information, and can judge whether to be paged according to the detection result, so that when only a small number of UE in one PO are paged, unnecessary power consumption caused by decoding the PDSCH by the terminal is avoided, and energy conservation of the terminal is realized.

In some optional embodiments, the detecting a physical downlink control channel PDCCH based on the first configuration information and determining whether to be paged includes:

if the PDCCH scrambled by the paging radio network temporary identifier P-RNTI is detected in the paging time PO corresponding to the terminal in the applicable position range of the first paging identifier and the PDCCH is determined to carry the first paging identifier, matching the first paging identifier corresponding to the terminal with the first paging identifier carried by the PDCCH;

under the condition that the first paging identification corresponding to the terminal is successfully matched with one first paging identification carried by the PDCCH, the terminal determines to be paged; or,

and under the condition that the first paging identification corresponding to the terminal is failed to be matched with all the first paging identifications carried by the PDCCH, the terminal determines that the terminal is not paged.

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

If the terminal detects the PDCCH scrambled by the P-RNTI in the PO corresponding to the terminal within the applicable position range of the first paging identifier, the terminal matches the first paging identifier corresponding to the terminal with the first paging identifier carried by the PDCCH, and if the first paging identifier corresponding to the terminal is consistent with the first paging identifier of a paged terminal carried by the PDCCH, the terminal determines that the terminal is paged successfully.

Optionally, if there is no identifier that is consistent with the first paging identifier corresponding to the terminal in the first paging identifier of the paged terminal carried by the PDCCH, it may be understood that the matching between the first paging identifier corresponding to the terminal and all the first paging identifiers carried by the PDCCH fails, and the terminal determines that no paging is performed.

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

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

and determining that the PDCCH carries a first paging identifier according to the format of Downlink Control Information (DCI) carried by the PDCCH.

Optionally, when multiplexing the existing DCI format1_0, the UE determines that the PDCCH carries the first paging identifier according to the content of the PDCCH. For example: and if the value of the Short Message indicator is 00, the PDCCH is identified to carry the first paging identifier.

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

In the embodiment of the application, when the PDCCH carries the first paging identifier, the time-frequency resource information of the PDSCH is not carried, so that the terminal which is not paged does not need to receive the PDSCH, thereby avoiding unnecessary power consumption caused by decoding the PDSCH by the terminal, realizing energy saving, and reducing network overhead because the PDCCH carries the first paging identifier.

In some optional embodiments, the detecting, based on the first configuration information, a physical downlink control channel PDCCH and determining whether to be paged includes:

if the PDCCH scrambled by the first paging identifier corresponding to the terminal is detected in the paging time PO corresponding to the terminal within the applicable position range of the first paging identifier, the terminal determines to be paged; or,

and the PDCCH scrambled by the first paging identifier corresponding to the terminal is not detected in the paging time PO corresponding to the terminal, and the terminal is determined not to be paged.

It will be appreciated that the PDCCH transmitted by the network may be a PDCCH applying an identity scrambling including a first paging identity of the paged terminal.

And if the PDCCH scrambled by the first paging identifier corresponding to the terminal is detected in the paging time PO corresponding to the terminal within the applicable position range of the first paging identifier, that is, if the PDCCH is detected by the terminal and the PDCCH is decoded by the first paging identifier corresponding to the terminal and decoding succeeds, the terminal determines to be paged.

And if the terminal detects the PDCCH and the PDCCH is decoded by applying the first paging identifier corresponding to the terminal and the decoding fails, the terminal determines that the PDCCH is not paged.

In the embodiment of the application, the terminal decodes the detected PDCCH by using the corresponding first paging identifier to determine whether the PDCCH is paged, and the non-paged terminal does not need to receive the PDSCH, so that unnecessary power consumption caused by decoding the PDSCH by the terminal is avoided, energy conservation of the terminal is realized, and network overhead can be reduced because the PDCCH does not need to carry scheduling information of the PDSCH.

Optionally, detecting the PDCCH to determine whether to be paged includes:

and if the PDCCH is detected in the paging time PO corresponding to the terminal in the applicable position range of the first paging identifier and the PDCCH is determined not to carry the first paging identifier, receiving a paging message according to a second paging identifier corresponding to the terminal.

The second paging identifier is a paging identifier adopted by a corresponding paging mechanism in 3GPP NR R15, and the paging identifier adopted by the corresponding paging mechanism in 3GPP NR R15 is described in the foregoing embodiments, and is not described herein again.

And if the PDCCH does not carry the first paging identifier according to the content of the PDCCH or the DCI format, the terminal receives the paging message according to the second paging identifier.

It can be understood that, when the condition for paging based on the first paging identifier cannot be achieved, for example, when at least one terminal does not support receiving of a paging message based on the first paging identifier, the number of terminals that the network needs to page is greater than a preset threshold, and the network does not support or does not start 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 15.

Optionally, on the basis of the foregoing embodiment, the paging method further includes:

acquiring system information of a newly resided cell;

if the system information of the newly residing cell cannot be matched with the applicable position range of the first paging identifier, executing at least one of the following steps:

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

reporting the applicable position range of the terminal moved out of the first paging identifier to network side equipment;

receiving configuration information of a new first paging identifier sent by network side equipment, and receiving a paging message by using the new first paging identifier;

and releasing the configuration information of the original first paging identifier.

Optionally, when the camping cell of the terminal changes, the terminal acquires system information of the new camping cell to determine whether the terminal moves out of the applicable position range of the first paging identifier.

Wherein the system information comprises at least one of: cell identification, tracking area TA identification and notification area RNA identification of a wireless access network.

If the identifier which is consistent with the system information of the newly residing cell cannot be found in the applicable position range of the first paging identifier, it can be understood that the system information of the newly residing cell cannot be matched with the applicable position range of the first paging identifier, that is, the terminal has moved out of the applicable range of the first paging identifier, the terminal cannot continue to support paging based on the first paging identifier, and the terminal performs at least one of the following:

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, and if receiving configuration information of a new first paging identifier sent by the network side device, the terminal receives a paging message by using the new first paging identifier, otherwise, the terminal receives the paging message according to a 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 moving out of the application range of the first paging identifier, the terminal releases the configuration information of the original first paging identifier. The release operation may be based on an indication from the network or may be performed automatically by the terminal.

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

and reporting terminal capability indication information to network side equipment, wherein the terminal capability indication information is used for indicating that the terminal supports paging based on the first paging identifier.

Optionally, when the terminal is capable of receiving the 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.

and receiving a first response message sent by the network side equipment, wherein the first response message is used for indicating the network side equipment to determine that the terminal capability indication information is received and/or informing the terminal to start the function of paging based on the 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 instruct the network side device to determine to receive the terminal capability indication information, and/or notify the terminal to start a paging function based on the first paging identifier.

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

receiving cell indication information sent by a network side device, wherein the cell indication information is used for indicating that a cell supports or starts a paging function based on a first paging identifier.

Optionally, the terminal receives a broadcast message sent by the network side device, where the broadcast message carries cell indication information, and the cell indication information is used to indicate that a cell supports or starts 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 at the corresponding PO.

when the terminal moves out of the tracking area or the notification area of the wireless access network, initiating a location area update process, and sending a tracking area update TAU request or a notification area update RNAU request of the wireless access network to the network side equipment;

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

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

The terminal receives a second response message sent by the network side device, where the second response message carries network indication information, and the network indication information is used to indicate that a cell corresponding to the TAI supports or starts a paging function based on the first paging identifier, or indicate that a cell corresponding to the TAI list supports or starts a paging function based on the first paging identifier, or indicate that a cell corresponding to the RNA supports or starts a paging function 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 identity at the corresponding PO.

The cell corresponding to the TAI refers to a cell with TAI related parameters of cell broadcast information consistent with the TAI; the cell corresponding to the TAI list refers to a cell with TAI related parameters of cell broadcast information consistent with one TAI in the TAI list; the cell corresponding to the RNA refers to the cell matched with the RNA configuration in the cell broadcast information.

Optionally, in a case that the first configuration information includes assistance information for acquiring the first paging identifier, the method further includes:

and the terminal determines a first paging identifier corresponding to the terminal based on the auxiliary information for acquiring the first paging identifier.

For example, the assistance information indicates that the part of the legacy UE ID other than the upper N bits and/or the lower M bits is the first paging identity. And the terminal determines a first paging identifier corresponding to the terminal based on the auxiliary information for acquiring the first paging identifier, and receives a paging message by using the first paging identifier.

Optionally, the first paging identifier includes one of:

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

removing last Log from second paging identifier₂The rest bits after N x Ns bits, wherein N is the number of paging frames in a discontinuous reception DRX period, and Ns is the number of paging moments PO in a paging frame;

Calculating a calculated identifier based on the cell identifier, the TA identifier or the RNA identifier, and the offset value;

and calculating the obtained identifier based on the cell identifier, the TA identifier or the RNA identifier and the second paging identifier.

Alternatively, 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 second paging identifier excluding the last Log₂The remaining bits after N Ns bits.

One principle is: the part of the second paging identity, which may be indicated by the PO location, is no longer carried in the first paging identity.

For example: assume that the NW configures the DRX cycle of the UE to be 1.28s (corresponding to T in 38.304). The network is configured with 4 (corresponding to Ns in 38.304) POs in every 10ms radio frame. Then, there are a total of 128 × 4 — 512 POs within the DRX cycle of the UE.

The UE selects which PO it should listen to the paging itself based on the last 9 bits of its paging ID (i.e., 512 PO locations may be indicated).

Then the last 9 bits of legacy UE ID should not be carried in the short ID.

Optionally, last Log in legacy UE ID₂(T/10ms) Ns bits bit should not be carried in the short ID.

Another formulation expresses: in 38.304, the UE-to-PO calculation formula is described, based on the parameters in the formula:

N is the number of paging frames in T in a DRX period, and Ns is the number of paging occasions PO in a paging frame.
