Specifically, when the network side device pages the terminal, it sends a paging message, 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, and the MT-SDT indication information may be used to indicate whether at least one terminal paged by the paging message performs MT-SDT, or the MT-SDT indication information is used to indicate whether the paging message At least one terminal that is paged performs MT-SDT.

The MT-SDT indication information can be obtained, for example, from a paging message, or from DCI of a scheduling 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 means that the first terminal is paged, and then determine whether the MT-SDT indicates the The first terminal executes MT-SDT. If the MT-SDT instructs the first terminal to execute MT-SDT, the first terminal executes MT-SDT. Otherwise, the terminal does not need to execute MT-SDT, that is, executes a normal paging response process.

If the paging message carries the MT-SDT indication, the first terminal can obtain the MT-SDT indication from the paging message; if the paging message does not carry the MT-SDT indication, for example, the first terminal can also obtain the MT-SDT indication from the paging message The MT-SDT indication is acquired in the DCI.

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

It should be noted that the execution of the MT-SDT involved in the embodiment of the present application includes: the terminal executes a process or behavior corresponding to the MT-SDT specified in the protocol.

In the method of the above embodiment, the terminal receives the paging message sent by the network side device, and obtains MT-SDT indication information, the MT-SDT indication information is used to indicate whether at least one terminal paged by the paging message performs MT-SDT, Or the MT-SDT indication information is used to instruct at least one terminal paged by 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 to execute MT-SDT , realizing the processing mechanism for the terminal to execute the MT-SDT, and the implementation complexity of the terminal is relatively low.

The MT-SDT indication information is carried by the downlink control information DCI of the scheduling paging message; or,

The MT-SDT indication information is indicated by the target DCI; the target DCI is the DCI of the dispatch paging message heard at the target paging occasion;

Wherein, the MT-SDT indication information indicated by the target DCI is used to instruct the terminal paged by the paging message to execute MT-SDT.

Specifically, the paging message can not only carry the identity of the paged terminal, but also carry 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. SDT, or MT-SDT indication information, is used to instruct one or more terminals paged by the paging message to execute MT-SDT; that is, the terminal can determine whether to execute MT-SDT according to the MT-SDT indication information.

The downlink control information DCI of the scheduling paging message can also carry MT-SDT indication information; the DCI can indicate whether one or more pages in the paging message perform MT-SDT, or the DCI carries the MT-SDT indication information, indicating that the paging The terminal paged in the paging message executes MT-SDT, and the DCI does not carry the MT-SDT indication information, which means that the terminal paged in the paging message does not need to perform MT-SDT, that is, the conventional paging response process is performed, that is, the first terminal It may also be determined whether to execute MT-SDT according to the MT-SDT indication information carried in the DCI.

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

For example, the first terminal A obtains a paging message, the paging message carries the MT-SDT indication information of the first terminal A, and instructs the first terminal A to perform MT-SDT, then the first terminal A performs MT-SDT;

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

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 used to schedule the paging message, carries the MT-SDT indication information, and the first terminal further determines whether to execute the MT-SDT according to the received MT-SDT indication information ; or by monitoring the target DCI at the target paging occasion to determine whether the terminal executes MT-SDT, if the target DCI is monitored, then execute MT-SDT, that is, the MT-SDT indication information can be carried in various ways, which is more flexible High, the implementation complexity of the terminal is low.

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 where the MT-SDT indication information is carried by the paging message, step 102 may be implemented in the following manner:

If the indication information for the first terminal in the MT-SDT indication information indicates to execute MT-SDT, then the first terminal executes MT-SDT; or,

If the MT-SDT indication information includes indication information for the first terminal, the first terminal executes MT-SDT;

Wherein, the indication information for the first terminal is obtained based on the MT-SDT indication information and the index of the identifier of the first terminal in the first paging record list in the paging message, and the indication information of the first terminal is indicated in the MT-SDT The index in the information corresponds to the index of the identifier of the first terminal in the first paging record list.

Specifically, the instruction information for the first terminal in the MT-SDT instruction information indicates to execute MT-SDT, for example, the value of the instruction information for the first terminal is the first preset value, indicating that the first terminal is instructed to execute MT-SDT. SDT; or the MT-SDT indication information includes indication information for the first terminal, indicating that the first terminal is instructed to execute MT-SDT; that is, whether the first terminal in the MT-SDT indication information indicates the execution of MT-SDT or MT- Whether the SDT indication information includes the indication information of the first terminal can determine whether the first terminal executes MT-SDT.

The indication information for the first terminal is obtained through the index of the MT-SDT indication information and the identity of the first terminal in the paging message, specifically based on the MT-SDT indication information and the identity of the first terminal in the paging message The index in the first paging record list (Paging Record List) is obtained, wherein, the index of the indication information of the first terminal in the MT-SDT indication information, and the identifier of the first terminal in the first paging record list corresponding to the index; that is, through the index of the first terminal's identifier in the first paging record list, and the index of the first terminal's indication information in the MT-SDT indication information, so that the first terminal can accurately know receive the MT-SDT indication information for the first terminal, and then determine whether to execute MT-SDT according to the indication information for the first terminal.

In the above embodiment, the first terminal can determine whether to execute MT-SDT through 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. Low, greater flexibility; In addition, through the position index of the first terminal's identifier in the first paging record list, and the corresponding relationship between the position index of the first terminal's indication information in the MT-SDT indication information, so that the first The terminal can accurately and quickly learn the MT-SDT indication information for the first terminal, and then 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 includes the identifier of the first terminal, the first terminal performs a conventional paging response process; or,

If the indication information for the first terminal in the MT-SDT indication information indicates that MT-SDT is not performed, the first terminal performs a normal paging response process; or,

If the MT-SDT indication information does not include indication information for the first terminal, and the paging message includes the identity of the first terminal, the terminal performs a conventional paging response process; or,

If the paging message does not include the identifier of the first terminal, the first terminal determines that it has not been 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 only needs to perform the normal paging response process. ;

If the indication information for the first terminal in the MT-SDT indication information indicates that MT-SDT is not performed, for example, the value of the indication information for the first terminal is the second preset value, which is used to indicate that the first terminal does not need to perform MT-SDT. SDT, if the first terminal is paged, the first terminal performs a conventional paging response process;

If the MT-SDT indication information does not include indication information for the first terminal, and the paging message includes the identity of the first terminal, the terminal performs a conventional paging response process; that is, the terminal paged in the paging message does not Indicated in the MT-SDT indication information, indicating that the corresponding terminal does not need to execute MT-SDT, and only needs to execute the normal paging response process;

If the terminal identifier is not included in the paging message, the terminal is not paged; that is, the terminals paged by the network side are all included in the paging message, and the terminals not included in the paging message are terminals that are not paged by the network side;

For example, the paging message includes the identity of the first terminal A, and the paging message does not carry MT-SDT indication information, then the first terminal A performs a conventional paging response process;

If the paging message includes the identity 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, the second preset value is 0, indicating that the called terminal does not MT-SDT needs to be executed, and the first terminal A executes the normal paging response process when the normal paging response process is performed;

If the paging message includes the identifier of the first terminal A, and the MT-SDT indication information does not include the indication information of the first terminal A, then the first terminal A performs a normal paging response process.

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

In one embodiment, the index of the identity of the first terminal in the first paging record list is the rank of the identity of the first terminal among the N target identifiers in the first paging record list, and the target identity is inactive The radio network temporary identifier I-RNTI, N is an integer greater than 0.

Specifically, the paged terminal has two kinds of identifiers, one is used to identify the terminal in the idle state of paging; the other is used to identify the terminal in the inactive state, that is, the temporary identifier of the inactive wireless network symbol fullI-RNTI; the terminal's identity in the first paging record list in the N target identification rank as an index, that is, the number of inactive terminals in the first paging record list is recorded as N, and The rank of each inactive terminal among the N inactive terminals is used as an index.

For example, the number of inactive terminals in the first paging record list is recorded as N, and N is 10, that is, the first paging record list includes 10 inactive terminals; the index is each inactive terminal If the first terminal A ranks second among the 10 inactive terminals, then the position index of terminal A is 2, and the starting value of the ranking is 1. What needs to be explained is the arrangement The initial value of the rank may also be 0, which is not limited in this embodiment of the present application.

For example, N is 5, and N target identifiers {A1, A2, A3, A4, A5}, wherein, the index of A1 in the N target identifiers in the first paging record list is 0, and the index of A2 in the first paging record list The index of the N target IDs in the record list is 1, the index of A3 in the N target IDs in the first paging record list is 2, and the index of A4 in the N target IDs in the first paging record list is 3, and the index of A5 in the N target identifiers in the first paging record list is 4;

The MT-SDT indication information is {B1, B2, B3, B4, B5}, and the indexes of B1, B2, B3, B4, and B5 in the MT-SDT indication information are 0, 1, 2, 3, and 4 in sequence. The identity of a terminal is A2, then the index of the identity of the first terminal in the N target identifiers in the first paging record list is 1, and the indication information for the first terminal in the MT-SDT indication information is B2 .

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

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

In the above embodiment, by recording the number of inactive terminals in the first paging record list as N, and using the arrangement position of each inactive terminal among the N inactive terminals as an index, so that Because the index and MT-SDT indication information are used to determine whether the first terminal executes MT-SDT, and the MT-SDT indication information only carries indication information for inactive terminals, the signaling overhead is relatively small.

In one embodiment, the paging message includes a first paging record list and an MT-SDT indication information list, the MT-SDT indication information list includes MT-SDT indication information, and the first paging record list includes all paged terminals The identity of the paged terminal includes the identity 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 identifier 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; wherein, the MT-SDT indication information is implemented through the MT-SDT indication information list, and the first paging record list includes the identifier of the terminal; The identification of the calling terminal is stored in a different list from the MT-SDT indication information, which is convenient for paging indication; the index of the indication information of the first terminal in the MT-SDT indication information list is the The indexes in the record list correspond, 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 and an MT-SDT indication information list B, where the identity of the paging terminal is recorded in list A, and the MT-SDT indication information is recorded in list B.

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, which is convenient for terminal paging and MT-SDT indication information. -SDT indication.

In an embodiment, the paging message includes a second paging record list, and the second paging record list is used to carry the identifiers of the terminals whose MT-SDT is triggered, wherein the identifiers of the terminals whose MT-SDT is triggered are arranged consecutively in the In the second paging record list; wherein, the second paging record list also includes an identifier of a terminal whose MT-SDT is not triggered, and/or, an identifier of a terminal that does not support MT-SDT;

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

Optionally, it may also include an identifier of a terminal whose MT-SDT is not triggered, and/or an identifier of a terminal that does not support MT-SDT; that is, through the second paging record list in the paging message, the first Whether the terminal executes 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 multiple paged terminals, where {a2, a3, a4} are IDs of terminals whose MT-SDT is triggered The identifiers, that is, the identifiers of the terminals whose MT-SDT is triggered are arranged consecutively, and the remaining identifiers are the identifiers of the terminals whose MT-SDT is not triggered, and/or the identifiers of the terminals that do not support MT-SDT.

For example, the paging message includes a second paging record list A, and the second paging record list A carries five MT-SDT-triggered terminal identifiers, and terminal A according to the second paging record list A of the paging message The five MT-SDT trigger terminal identifiers determine whether to execute MT-SDT.

Optionally, the MT-SDT indication information includes the start index and/or the number of identifiers of terminals whose MT-SDT is triggered in the second paging record list.

Specifically, in this embodiment, the MT-SDT indication information may indicate the start index and/or the number of identities of terminals whose MT-SDT is triggered in the second paging record list.

In the case where the MT-SDT indication information indicates the start index and/or number of the identifier of the terminal whose MT-SDT is triggered in the second paging record list, the MT-SDT indication information may be indicated by a paging message, or Can be indicated by DCI.

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

Specifically, by continuously arranging the identifiers of the M terminals whose MT-SDT is triggered in the first or last M positions in the second paging record list, the first terminal only needs to know the starting index or number to determine which are The identification of the terminal whose MT-SDT is triggered is convenient for determining whether the terminal executes MT-SDT, can improve efficiency, and has less signaling overhead.

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

In the above embodiments, by continuously arranging the identities of the terminals whose MT-SDT is triggered, it is convenient to determine whether the terminal executes MT-SDT, which improves the paging efficiency, and the signaling overhead is small.

In an embodiment, when the MT-SDT indication information is carried by the DCI of the scheduling paging message, the first terminal may perform MT-SDT in the following manner:

If the MT-SDT indication information indicates to execute MT-SDT, and the paging message includes the identifier of the first terminal, then the first terminal executes MT-SDT.

Specifically, if the MT-SDT indication information indicates the execution of MT-SDT, for example, the value of the MT-SDT indication information indicates that the execution of MT-SDT is a third preset value, which can be indicated by the value of the MT-SDT indication information Whether to execute MT-SDT; when the paging message includes the identifier of the first terminal, and the value of the MT-SDT indication information is the third preset value, it means that the first terminal is paged by the network, and the first terminal executes MT-SDT .

For example, if the MT-SDT indication information indicates the execution of MT-SDT, it may indicate that all the terminals paged in the paging message need to perform MT-SDT, and if the MT-SDT indication information indicates that MT-SDT is not performed, it may indicate that the paging message None of the terminals being paged in MT-SDT need to execute MT-SDT. There is no need to separately indicate each terminal to be paged in the paging message, and the signaling overhead is relatively small.

In the above embodiments, the first terminal can determine whether to execute MT-SDT by using the MT-SDT indication information indicated by the DCI to indicate whether to execute MT-SDT, which has low implementation complexity and small signaling overhead.

In an embodiment, if the MT-SDT indication information indicates that the MT-SDT is not to be performed, and the paging message includes the identifier of the first terminal, the first terminal performs a normal paging response process; or,

Specifically, if the first terminal monitors the target DCI at the target paging occasion, and the paging message includes the identity of the first terminal, the first terminal executes MT-SDT; that is, by monitoring the target paging occasion, the first terminal determines the Whether to perform MT-SDT; when the first terminal monitors the target DCI at the target paging occasion, and the paging message includes the first terminal's identifier, it means that the first terminal is paged by the network, and instructs the first terminal to perform MT-SDT .

All the terminals paged in the paging message scheduled by the target DCI need to execute MT-SDT, and there is no need to indicate each terminal separately, and the signaling overhead is relatively small.

For example, the DCI monitored at the target paging occasion is the target DCI, and the DCI monitored at other paging occasions may indicate that the terminals paged in the paging message scheduled by the DCI do not need to perform MT-SDT, but perform regular Page response procedure.

In the above embodiments, the target DCI indicates the MT-SDT indication information, and the terminal can determine whether to execute the MT-SDT according to the DCI and the paging message, so the implementation complexity is low and the signaling overhead is small.
