Currently, the format of the air interface paging message is as follows:

in a Paging message, a Paging Record list (Paging Record List) is carried, the Paging Record list carries at least 1 and at most a maximum allowable number (MaxNrofPageRec) of Paging records (Paging Record), and each Paging Record carries a Paging identifier (ue_identity) of a paged terminal; i.e. one paging message may indicate that the maximum allowed number (MaxNrofPageRec) of terminals are paged.

The terminal to be paged has two kinds of identifiers, one is used for paging the terminal in idle state, namely ng-5G-S-TMSI; another type of terminal for paging an inactive (inactive) state is the fulll i-RNTI. The terminal receiving the paging message is in one of an idle state or an inactive state.

In NR system, paging message is scheduled by downlink control information (Downlink Control Information, DCI) format 1_0; the DCI may also carry a short message (short message), which is specifically determined by a short message indication (short message indicator) in the DCI, and the specific meaning is shown in table 1.

According to the paging indication method, the terminal receives the paging message sent by the network side equipment, acquires the called small data transmission (Mobile Terminated Small Data Transmission, MT-SDT) indication information, can determine whether the corresponding terminal is paged by the network according to the content in the paging message, and can determine whether the corresponding terminal executes MT-SDT according to the indication of the MT-SDT indication information.

Alternatively, the method in the embodiment of the present application is directed to a terminal in an inactive state, i.e. determining whether the paging terminal performs MT-SDT, and the terminal may be a terminal in an inactive state.

The paging indication method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

Fig. 2 is a flowchart of an embodiment of a paging indication method according to an embodiment of the present invention. As shown in fig. 2, the method provided in this embodiment includes:

step 101, a first terminal receives paging information sent by network side equipment and acquires called small data transmission MT-SDT indication information; the paging message is used for indicating a terminal paged by the network side equipment; the MT-SDT indication information is used for indicating whether at least one terminal paging the paging message executes MT-SDT or not, or the MT-SDT indication information is used for indicating at least one terminal paging the paging message to execute MT-SDT;

Specifically, when the network side device pages the terminal, a paging message is sent, and the paging message indicates the terminal to be paged, for example, the paging message carries the identifier of the terminal to be paged.

The first terminal may further obtain MT-SDT indication information, which may be used to indicate whether the at least one terminal paged by the paging message performs MT-SDT, or MT-SDT indication information may be used to indicate that the at least one terminal paged by the paging message performs MT-SDT.

The MT-SDT indication information may be obtained, for example, from a paging message or from DCI scheduling a paging message.

Step 102, the first terminal executes MT-SDT according to the MT-SDT indication information.

Specifically, the first terminal may execute MT-SDT based on the MT-SDT indication information, if the paging message includes the identifier of the first terminal, it indicates that the first terminal is paged, and further determines whether the MT-SDT indicates the first terminal to execute MT-SDT, if the MT-SDT indicates the first terminal to execute MT-SDT, the first terminal executes MT-SDT, otherwise, the terminal does not need to execute MT-SDT, i.e. execute a conventional paging response procedure.

If the paging message carries the MT-SDT indication, the first terminal may acquire the MT-SDT indication from the paging message, and if the paging message does not carry the MT-SDT indication, the first terminal may also acquire the MT-SDT indication from DCI, for example.

For example, after the first terminal a obtains the paging message, it is determined that the first terminal a is a terminal for network paging according to the specific content of the paging message, and the MT-SDT instructs the first terminal a to execute the MT-SDT, and then the first terminal a executes the MT-SDT.

It should be noted that, the executing MT-SDT in the embodiment of the present application includes: the terminal executes the corresponding flow or behavior of MT-SDT specified by the protocol.

According to the method, the terminal receives the paging message sent by the network side equipment and acquires MT-SDT indication information, wherein the MT-SDT indication information is used for indicating whether at least one terminal paging the paging message executes MT-SDT or not, or the MT-SDT indication information is used for indicating at least one terminal paging the paging message to execute MT-SDT, the first terminal executes MT-SDT according to the MT-SDT indication information, and the first terminal can determine whether the MT-SDT needs to be executed or not, so that a processing mechanism of executing MT-SDT by the terminal is realized, and the terminal implementation complexity is low.

In an embodiment, the MT-SDT indication may be implemented by at least one of:

MT-SDT indication information is carried by paging information; or alternatively, the first and second heat exchangers may be,

MT-SDT indication information is carried by downlink control information DCI of scheduling paging information; or alternatively, the first and second heat exchangers may be,

MT-SDT indication information is indicated by target DCI; the target DCI is DCI of a scheduling paging message monitored at a target paging occasion;

the MT-SDT indication information indicated by the target DCI is used for indicating the terminal paging by the paging message to execute MT-SDT.

Specifically, the paging message may carry not only the identifier of the terminal to be paged, but also MT-SDT indication information, where the MT-SDT indication information is used to indicate whether one or more terminals paged by the paging message perform MT-SDT, or the MT-SDT indication information is used to indicate one or more terminals paged by the paging message perform MT-SDT; i.e., the terminal can determine whether to execute MT-SDT based on the MT-SDT indication information.

Downlink control information DCI of the scheduling paging message can also carry MT-SDT indication information; the DCI may indicate whether one or more paging terminals in the paging message execute MT-SDT or not, or the DCI carries the MT-SDT indication information, which indicates that paging terminals in the paging message execute MT-SDT, and the DCI does not carry the MT-SDT indication information, which indicates that paging terminals in the paging message do not need to execute MT-SDT, that is, execute a conventional paging response procedure, that is, the first terminal may also determine whether to execute MT-SDT according to the MT-SDT indication information carried in the DCI.

In addition, the target DCI monitored by the target paging occasion can also instruct the paging terminal in the paging message scheduled by the DCI to execute MT-SDT; i.e., when the terminal monitors the target DCI at the target paging occasion, it is indicated that the first terminal needs to execute MT-SDT.

For example, the first terminal a acquires a paging message, where the paging message carries MT-SDT indication information of the first terminal a and indicates the first terminal a to execute MT-SDT, and then the first terminal a executes MT-SDT;

the first terminal B acquires downlink control information DCI, MT-SDT indication information carried in the DCI indicates to execute MT-SDT, and then the first terminal B executes MT-SDT;

and the first terminal C monitors the target DCI at the target paging occasion, and then the first terminal C executes MT-SDT.

In the above embodiment, the paging message or the downlink control information DCI for scheduling the paging message carries MT-SDT indication information, and the first terminal further determines whether to execute MT-SDT according to the received MT-SDT indication information; or monitoring target DCI at target paging occasion to determine whether the terminal executes MT-SDT, if the target DCI is monitored, executing MT-SDT, namely carrying MT-SDT indication information in various modes, and having higher flexibility and lower complexity of terminal realization.

Optionally, if the paging message carries MT-SDT indication information, the first terminal determines whether to execute MT-SDT according to the MT-SDT indication information.

In an embodiment, in the case that the MT-SDT indication information is carried by the paging message, step 102 may be implemented as follows:

if the indication information of the MT-SDT indication information aiming at the first terminal indicates to execute the MT-SDT, the first terminal executes the MT-SDT; or alternatively, the first and second heat exchangers may be,

if the MT-SDT indication information comprises indication information aiming at the first terminal, the first terminal executes MT-SDT;

the indication information of the first terminal is obtained based on the MT-SDT indication information and an index of the first terminal in a first paging record list in the paging message, and the index of the indication information of the first terminal in the MT-SDT indication information corresponds to the index of the first terminal in the first paging record list.

Specifically, the indication information of the first terminal in the MT-SDT indication information indicates to execute the MT-SDT, for example, the indication information of the first terminal takes a value as a first preset value, which indicates to instruct the first terminal to execute the MT-SDT; or the MT-SDT indication information comprises indication information aiming at the first terminal, namely the indication information indicates the first terminal to execute MT-SDT; that is, whether the first terminal performs MT-SDT can be determined by whether the first terminal instructs to perform MT-SDT or whether the MT-SDT instruction information includes the instruction information of the first terminal in the MT-SDT instruction information.

The indication information for the first terminal is obtained through the MT-SDT indication information and the index of the identification of the first terminal in the paging message, specifically based on the MT-SDT indication information and the index of the identification of the first terminal in a first paging record list (Paging Record List) in the paging message, wherein the index of the indication information of the first terminal in the MT-SDT indication information corresponds to the index of the identification of the first terminal in the first paging record list; namely, through the index of the identifier of the first terminal in the first paging record list and the corresponding relation of the index of the indication information of the first terminal in the MT-SDT indication information, the first terminal can accurately acquire the MT-SDT indication information aiming at the first terminal, and further determine whether to execute MT-SDT according to the indication information aiming at the first terminal.

In the above embodiment, the first terminal may determine whether to execute MT-SDT by using the indication for the first terminal in the MT-SDT indication information or whether the MT-SDT indication information includes the indication information of the first terminal, which has lower complexity and greater flexibility in terminal implementation; in addition, through the corresponding relation between the position index of the identifier of the first terminal in the first paging record list and the position index of the indication information of the first terminal in the MT-SDT indication information, the first terminal can accurately and rapidly acquire the MT-SDT indication information aiming at the first terminal, and further determine whether to execute MT-SDT.

In an embodiment, the paging indication method further includes:

if the paging message does not carry MT-SDT indication information and the paging message comprises the identification of the first terminal, the first terminal executes a conventional paging response process; or alternatively, the first and second heat exchangers may be,

if the indication information of the MT-SDT indication information aiming at the first terminal indicates that the MT-SDT is not executed, the first terminal executes a conventional paging response process; or alternatively, the first and second heat exchangers may be,

if the MT-SDT indication information does not include indication information aiming at the first terminal and the paging message includes the identification of the first terminal, the terminal executes a conventional paging response process; or alternatively, the first and second heat exchangers may be,

if the paging message does not include the identification of the first terminal, the first terminal determines that the paging message is not paged.

Specifically, if the paging message does not carry MT-SDT indication information and the paging message includes the identifier of the terminal, it means that the terminal included in the paging message does not need to execute MT-SDT, and executes the conventional paging response procedure;

if the indication information of the MT-SDT indication information for the first terminal indicates that the MT-SDT is not executed, for example, the indication information for the first terminal takes a value of a second preset value for indicating that the first terminal does not need to execute the MT-SDT, if the first terminal is paged, the first terminal executes a conventional paging response process;

If the MT-SDT indication information does not include indication information aiming at the first terminal and the paging message includes the identification of the first terminal, the terminal executes a conventional paging response process; i.e. the paging terminal in the paging message is not indicated in the MT-SDT indication information, which means that the corresponding terminal does not need to execute MT-SDT and executes the routine paging response process;

if the paging message does not include the identification of the terminal, the terminal is not paged; that is, the terminals paged by the network side are included in the paging message, and the terminals not included in the paging message are terminals not paged by the network side;

for example, the paging message includes an identifier of the first terminal a, and if the paging message does not carry MT-SDT indication information, the first terminal a executes a conventional paging response procedure;

if the paging message includes the identifier of the first terminal a, the value of the indication information of the first terminal a in the MT-SDT indication information is a second preset value, for example, a second preset value of 0 indicates that the called terminal does not need to execute the MT-SDT, and if the conventional paging response process is executed, the first terminal a executes the conventional paging response process;

if the paging message includes the identifier of the first terminal a, the MT-SDT indication information does not include the indication information of the first terminal a, and the first terminal a executes a conventional paging response procedure.

The conventional paging response procedure includes one of the following: release 15 paging response procedure and non-MT-SDT paging response procedure for LTE and NR.

In an embodiment, the index of the identifier of the first terminal in the first paging record list is the arrangement order of the identifier of the first terminal in N target identifiers in the first paging record list, the target identifiers are inactive radio network temporary identifiers I-RNTI, and N is an integer greater than 0.

Specifically, the paged terminal has two kinds of identifiers, one is used for identifying the terminal in idle state; another type of terminal for identifying an inactive (inactive) state, i.e. an inactive radio network temporary identifier fulll i-RNTI; the arrangement bit order of the identifiers of the terminals in N target identifiers in the first paging record list is used as an index, namely the number of the inactive state terminals in the first paging record list is recorded as N, and the arrangement bit order of each inactive state terminal in N inactive state terminals is used as an index.

For example, the number of inactive state terminals in the first paging record list is recorded as N, where N is 10, that is, the first paging record list includes 10 inactive state terminals; the index is the arrangement order of each inactive state terminal, if the arrangement order of the first terminal a among the 10 inactive state terminals is 2 nd, the position index of the terminal a is 2, the start value of the arrangement order is 1, and it should be noted that the start value of the arrangement order may also be 0, which is not limited in this embodiment of the present application.

For example, N is 5,N target identifications { A1, A2, A3, A4, A5}, where A1 has an index of 0 among the N target identifications in the first paging record list, A2 has an index of 1 among the N target identifications in the first paging record list, A3 has an index of 2 among the N target identifications in the first paging record list, A4 has an index of 3 among the N target identifications in the first paging record list, and A5 has an index of 4 among the N target identifications in the first paging record list;

the MT-SDT indication information is { B1, B2, B3, B4, B5}, indexes of B1, B2, B3, B4 and B5 in the MT-SDT indication information are sequentially 0, 1, 2, 3 and 4, if the identification of the first terminal is A2, the index of the identification of the first terminal in N target identifications in the first paging record list is 1, and the indication information of the MT-SDT indication information aiming at the first terminal is B2.

Illustratively, N is 5, the first paging record list { A1, C2, A3, C3, A4, A5}, where A1, A2, A3, A4, and A5 are identities of 5 inactive state terminals, and C1, C2, and C3 represent identities of terminals in an idle state. A1, A2, A3, A4 and A5 have indexes of 0, 1, 2, 3 and 4 in N target identifiers in the first paging record list respectively;

In this manner, the MT-SDT indication information does not include indication information of the terminal in the idle state, so that signaling overhead can be saved.

In the above embodiment, the number of inactive state terminals in the first paging record list is denoted as N, and the arrangement bit of each inactive state terminal in the N inactive state terminals is used as an index, so that it is determined whether the first terminal executes MT-SDT or not by using the index and MT-SDT indication information, and only indication information for the inactive state terminal is carried in the MT-SDT indication information, which has small signaling overhead.

In an embodiment, the paging message includes a first paging record list and an MT-SDT indication information list, the MT-SDT indication information list including MT-SDT indication information, the first paging record list including identifications of all paged terminals, the identifications of the paged terminals including identifications of the first terminal;

The index of the indication information of the first terminal in the MT-SDT indication information list corresponds to the index of the identification of the first terminal in the first paging record list.

Specifically, the paging message includes a first paging record list and an MT-SDT indication information list; the MT-SDT indication information is realized through an MT-SDT indication information list, and the first paging record list comprises the identification of the terminal; namely, the paging terminal identification and MT-SDT indication information are stored in different lists, so that paging indication is facilitated; the index of the indication information of the first terminal in the MT-SDT indication information list corresponds to the index of the identification of the first terminal in the first paging record list, so that the first terminal can quickly and accurately determine whether to execute MT-SDT.

For example, the paging message includes a first paging record list a in which the identity of the paging terminal is recorded and an MT-SDT indication information list B in which the MT-SDT indication information is recorded.

In the above embodiment, the paging message includes the first paging record list and the MT-SDT indication information list, that is, the paging terminal identifier and the MT-SDT indication information are stored in different lists, so as to facilitate paging and MT-SDT indication of the terminal.

In an embodiment, the paging message includes a second paging record list, where the second paging record list is used to carry the identifier of the terminal triggered by the MT-SDT, and the identifier of the terminal triggered by the MT-SDT is continuously arranged in the second paging record list; the second paging record list further comprises the identification of the terminal which is not triggered by the MT-SDT and/or the identification of the terminal which does not support the MT-SDT;

the first terminal may perform MT-SDT as follows:

in the case that the identification of the terminal whose MT-SDT is triggered includes the identification of the first terminal, the first terminal executes the MT-SDT.

Specifically, the paging message includes a second paging record list, where the second paging record list is used to carry the identification of the terminal triggered by MT-SDT, and the identification of the terminal triggered by MT-SDT is continuously arranged in the second paging record list.

Optionally, the method can also comprise the identification of the terminal which is not triggered by the MT-SDT and/or the identification of the terminal which does not support the MT-SDT; i.e. by means of the second list of paging records in the paging message, it can be determined whether the first terminal performs MT-SDT and whether the first terminal supports MT-SDT.

For example, the second paging record list includes identifiers { a1, a2, a3, a4, a5, a6} of a plurality of paged terminals, where { a2, a3, a4} is an identifier of a terminal for which MT-SDT is triggered, i.e., identifiers of terminals for which MT-SDT is triggered are continuously arranged together, and the remaining identifiers are identifiers of terminals for which MT-SDT is not triggered, and/or identifiers of terminals for which MT-SDT is not supported.

For example, the paging message includes a second paging record list a, where the second paging record list a carries identifiers of terminals whose MT-SDT is triggered, and the terminal a determines whether to execute the MT-SDT according to the identifiers of the terminals whose MT-SDT is triggered in the second paging record list a of the paging message.

Optionally, the MT-SDT indication information includes a starting index and/or number of the MT-SDT triggered terminals identified in the second paging record list.

Specifically, in this embodiment, the MT-SDT indication information may indicate a starting index and/or number of the MT-SDT triggered terminal identified in the second paging record list.

In case the MT-SDT indication information indicates the starting index and/or number of the terminal whose MT-SDT is triggered, which may be indicated by paging message or by DCI.

In one embodiment, the identities of the M terminals whose MT-SDT is triggered are arranged in succession in M positions at the head or tail in the second paging record list; m is an integer greater than 0.

Specifically, the identifiers of the M terminals triggered by the MT-SDT are continuously arranged at M positions at the head or tail in the second paging record list, and the first terminal only needs to know the starting index or number to determine which are the identifiers of the terminals triggered by the MT-SDT, so that it is convenient to determine whether the terminal executes the MT-SDT, the efficiency can be improved, and the signaling overhead is smaller.

M may be a preset value, such as a protocol pre-definition or a network side pre-configuration or a terminal pre-configuration, etc.

In the above embodiment, the identifiers of the terminals triggered by the MT-SDT are continuously arranged, so that it is convenient to determine whether the terminals execute the MT-SDT, paging efficiency is improved, and signaling overhead is small.

In an embodiment, in the case that the MT-SDT indication information is carried by DCI of the scheduled paging message, the first terminal may perform MT-SDT as follows:

if the MT-SDT indication information indicates to execute the MT-SDT and the paging message comprises the identification of the first terminal, the first terminal executes the MT-SDT.

Specifically, if the MT-SDT indication information indicates that the MT-SDT is executed, for example, the MT-SDT is executed by the value of the MT-SDT indication information being a third preset value, the value of the MT-SDT indication information may be used to indicate whether to execute the MT-SDT; when the paging message includes the identifier of the first terminal and the value of the MT-SDT indication information is a third preset value, the first terminal is paged by the network, and the first terminal executes MT-SDT.

For example, the MT-SDT indication information indicates that the MT-SDT is executed, which may indicate that the paged terminals in the paging message all need to execute the MT-SDT, and the MT-SDT indication information indicates that the MT-SDT is not executed, which may indicate that the paged terminals in the paging message all need not execute the MT-SDT. And each terminal paged in the paging message does not need to be respectively indicated, so that the signaling overhead is small.

In the above embodiment, through the MT-SDT indication information indicated by the DCI, whether to execute the MT-SDT is indicated, the first terminal may determine whether to execute the MT-SDT, which has low implementation complexity and low signaling overhead.

In an embodiment, if the MT-SDT indication information indicates that the MT-SDT is not executed and the paging message includes an identifier of the first terminal, the first terminal executes a conventional paging response procedure; or alternatively, the first and second heat exchangers may be,

Specifically, if the MT-SDT indication information indicates that the MT-SDT is not executed, for example, the value is a fourth preset value, that is, whether the MT-SDT is executed may be indicated by the value of the MT-SDT indication information; when the paging message includes the identifier of the first terminal and the value of the MT-SDT indication information is a fourth preset value, the first terminal is paged by the network, and the first terminal executes a conventional paging response process.

In an embodiment, the MT-SDT indication is carried by reserved bits in the short message indication field in the DCI or by reserved bits outside the short message indication field in the DCI.

Specifically, as shown in table 1 and table 2, there is a reserved bit in the short message indication field in the DCI, and there is a reserved bit outside the short message indication field in the DCI, that is, there is a reserved bit in the DCI and in the short message of the DCI, and the MT-SDT indication information may be carried by the reserved bit.

According to the embodiment, the MT-SDT indication information is carried in a plurality of reserved bit modes, so that the flexibility is low, and the implementation complexity is low.

In an embodiment, in the case that the MT-SDT indication information is indicated by the target DCI, the first terminal may perform MT-SDT by:

if the first terminal monitors the target DCI at the target paging occasion and the paging message comprises the identification of the first terminal, the first terminal executes MT-SDT.

Specifically, if the first terminal monitors the target DCI at the target paging occasion and the paging message includes the identifier of the first terminal, the first terminal executes MT-SDT; namely, determining whether the first terminal executes MT-SDT or not by monitoring the target paging occasion; when the first terminal monitors the target DCI at the target paging occasion, and the paging message comprises the identification of the first terminal, the first terminal is paged by the network, and the first terminal is instructed to execute MT-SDT.

The paging terminals in the paging message scheduled by the target DCI need to execute MT-SDT, each terminal does not need to be indicated, and the signaling overhead is small.

For example, the DCI monitored by the target paging occasion is the target DCI, and other paging occasions monitor the DCI, which may indicate that the paging terminal in the paging message scheduled by the DCI does not need to execute MT-SDT, but executes the conventional paging response procedure.

In the above embodiment, the terminal may determine whether to execute MT-SDT according to the DCI and the paging message by indicating the MT-SDT indication information by the target DCI, so that the implementation complexity is low and the signaling overhead is low.

In an embodiment, if the first terminal does not monitor the target DCI at the target paging occasion and the paging message includes the identifier of the first terminal, the first terminal executes a conventional paging response procedure; or alternatively, the first and second heat exchangers may be,

if the first terminal monitors the target DCI at the target paging occasion and the paging message does not include the identification of the first terminal, the first terminal determines that the paging is not performed.

Optionally, the target paging occasion is determined based on at least one of the following information configured to the MT-SDT capable terminal, the at least one information including: bandwidth part BWP, core set CoreSet, search space SS or radio network temporary identifier RNTI.

Specifically, if the first terminal does not monitor the target DCI at the target paging occasion and the paging message includes the identifier of the first terminal, the first terminal executes a conventional paging response process; determining whether the terminal executes MT-SDT by monitoring target DCI at target paging occasion; whether to be paged is determined by whether an identification of the first terminal is included in the paging message.

In an embodiment, the paging message comprises a third paging record list and/or a fourth paging record list;

the third paging record list is used for indicating the identification of at least one second terminal, the at least one second terminal is a terminal which does not support MT-SDT, the fourth paging record list is used for indicating the identification of at least one third terminal, and the at least one third terminal is a terminal which supports MT-SDT.

Specifically, the paging message includes a third paging record list and/or a fourth paging record list; i.e. the terminals not supporting MT-SDT and/or the terminals supporting MT-SDT are indicated by the third paging record table and the fourth paging record table, respectively.

Optionally, the fourth paging record list is further used to indicate whether the at least one third terminal is triggered to execute the MT-SDT.

The method of the above embodiment, through the paging message including the third paging record list and/or the fourth paging record list, enables the terminal to quickly determine whether to execute MT-SDT, which is more efficient.

Alternatively, the first terminal may perform MT-SDT by:

in case the at least one third terminal's identity comprises the first terminal's identity and the fourth paging record list indicates that the first terminal is triggered to execute MT-SDT, the first terminal executes MT-SDT.

Specifically, at least one third terminal is a terminal supporting MT-SDT, where the identifier of the at least one third terminal includes the identifier of the first terminal, and the fourth paging record list indicates that the first terminal is triggered to execute MT-SDT, that is, indicates that the first terminal supports MT-SDT, and indicates that the first terminal is triggered to execute MT-SDT, the first terminal executes MT-SDT.

In the above embodiment, the terminal supporting MT-SDT is indicated by the fourth paging record list, and is triggered to execute MT-SDT, so that the terminal can quickly determine whether to execute MT-SDT, which is high in efficiency.

in case the identity of the at least one second terminal comprises the identity of the first terminal, the first terminal performs a conventional paging response procedure;

and under the condition that the identifiers of all the second terminals and the identifiers of all the third terminals do not comprise the identifier of the first terminal, the first terminal determines that the first terminal is not paged.

Specifically, in the case that the at least one identifier of the third terminal includes the identifier of the first terminal, and the fourth paging record list does not indicate that the first terminal is triggered to execute MT-SDT, that is, the first terminal is a terminal supporting MT-SDT, but the first terminal is not triggered to execute MT-SDT, the first terminal executes a conventional paging response procedure;

In case that the at least one second terminal identification includes the first terminal identification, i.e. the first terminal is a terminal not supporting MT-SDT, the first terminal performs a conventional paging response procedure;

Optionally, the first maximum allowed number is configured for the network side device or predefined for the protocol.

Specifically, in one paging message, it may be indicated that the first maximum allowed number (MaxNrofPageRec) of terminals is paged; the number of the total identifiers in the third paging record list and the fourth paging record list is smaller than or equal to the first maximum allowable number; or, the number of the identifiers included in each of the third paging record list and the fourth paging record list is less than or equal to the first maximum allowable number; optionally, the first maximum allowed number is configured for the network side device or predefined for the protocol.

In an embodiment, the paging message comprises a fifth paging record list and/or a sixth paging record list;

the fifth paging record list is used for indicating the identification of at least one fourth terminal, the at least one fourth terminal is a terminal of which MT-SDT is not triggered, and the sixth paging record list is used for indicating the identification of at least one fifth terminal, and the at least one fifth terminal is a terminal of which MT-SDT is triggered.

In the above embodiment, the first terminal may quickly determine whether to execute MT-SDT through the fifth paging record list and/or the sixth paging record list in the paging message, which is more efficient.

In an embodiment, in case the identity of the at least one fifth terminal comprises the identity of the terminal, the first terminal performs MT-SDT;

in case the identification of the at least one fourth terminal comprises the identification of the first terminal, the first terminal performs a conventional paging response procedure;

in case that the identities of all fourth terminals and all fifth terminals do not comprise the identity of the first terminal, the first terminal determines not to be paged.

Specifically, in the case that the identifier of the at least one fifth terminal includes the identifier of the first terminal, that is, the first terminal is triggered to execute MT-SDT, the first terminal executes MT-SDT; in case the at least one fourth terminal's identity comprises the first terminal's identity, i.e. the first terminal is not triggered to perform MT-SDT, the first terminal performs a conventional paging response procedure.

In an embodiment, the number of total identities in the fifth list of paging records and the sixth list of paging records is less than or equal to the second maximum allowable number; or, the number of identities included in each of the fifth paging record list and the sixth paging record list is less than or equal to the second maximum allowable number.

Optionally, the second maximum allowable number is configured for the network side device or predefined for the protocol.

The first maximum allowable number and the second maximum allowable number may be the same or different.

In one embodiment, a terminal a in an RRC Inactive active state receives a paging message, where the paging message carries a paging record list including a paged terminal identifier and MT-SDT indication information;

terminal a determines whether to execute MT-SDT by including a paging record list identified by the paged terminal and MT-SDT indication information in the paging message.

Specifically, the terminal A compares the terminal identification in the paging record list with the terminal identification in the paging record list of the paged terminal, and presumes that the index of the identification of the terminal A in the paging record list is M; for example, the MT-SDT indication information list is 1010100000, and assuming that M is 5, the value of the 5 th indication information is 1, which indicates that the terminal a executes MT-SDT.

Optionally, the value of the element in the MT-SDT indication information is a first preset value to indicate the corresponding terminal to execute MT-SDT; the value is a first preset value, and the corresponding terminal is instructed to execute a conventional paging response process; or, optionally, the element is carried to instruct the corresponding terminal to execute MT-SDT; the element is not carried to instruct the corresponding terminal to perform a conventional paging response procedure.

Optionally, the MT-SDT information list only carries indication information of the terminal in the inactive state, that is, the MT-SDT information list length is the number of UEs in the inactive state that are paged in the paging message.

For example, Q of the first M paged terminal identifiers in the paging message are identified by using a fulll i-RNTI, and the P terminal identifiers are identified by using a ng-5G-S-TMSI, where m=p+q, and it is assumed that terminal a is the Q-th terminal in the non-activated state that is paged;

the terminal A can determine own MT-SDT indication information according to the index in the fullI-RNTI mark in the paging record list, so as to determine whether to execute MT-SDT;

for example, the MT-SDT indication information list is 1010100000, and assuming that Q is 7, the value of the 7 th indication information is 0, which means that the terminal a does not need to perform MT-SDT, and performs a conventional paging response procedure.

In an embodiment, the terminal a receives a paging message, where the paging message carries a paging record list including the identifier of the terminal to be paged, but does not carry MT-SDT indication information;

since the paging message does not carry MT-SDT indication information, terminal a performs a conventional paging response procedure.

In one embodiment, a terminal a receives a paging message, where the paging message carries a paging record list including an identifier of a terminal to be paged and MT-SDT indication information;

terminal a determines whether to execute MT-SDT through the paging record list and MT-SDT indication information.

Specifically, the terminal A determines the index of the identifier of the terminal A in a first paging record list by comparing with the identifier of the terminal in the paging record list in the paging message;

if the first M pieces of paging UE identification in the paging message are identified by ng-5G-S-TMSI, the identification of P pieces of terminals is identified by ng-5G-S-TMSI; there are Q identified with the fulll i-RNTI, i.e. m=p+q, assuming terminal a as the Q-th paged inactive terminal. Namely, the index of the terminal A is Q;

if the length of the MT-SDT indication information list is smaller than Q, that is, the MT-SDT indication information list does not carry MT-SDT indication information of the terminal A, the terminal A executes a conventional paging response process, so that signaling overhead can be reduced.

For example, MT-SDT indicates a list of information: 10101 assuming that the index of the terminal in the paging record list is 6, a conventional paging response procedure is performed.
