The first indication information may be identification information and/or grade information of the synchronous transmission group, and the transmission mode may include periodic transmission or conditional triggering, which is not limited in the embodiment of the present invention.

Optionally, when the transmission delay information is forwarded by the second core network element, the first request message (i.e. the query or subscription message) may be sent by the second core network element to the base station or the network forwarding node, i.e. the second core network element may subscribe or query the transmission delay information to the base station or the network forwarding node, and then the second core network element reports the transmission delay information to the first core network element.

The following describes, in connection with a specific embodiment, transmission delay information obtained by a first core network element:

Example 1: the first core network element obtains first delay information.

Example 1.1: the first core network element sends a first request message to the base station, wherein the first request message is used for indicating the base station to send first delay information; and the base station sends a first message to the first core network element according to the first request message, wherein the first message carries first delay information.

The first delay information may be measured by the base station or measured by the terminal.

As shown in fig. 2, a flowchart of a base station measuring first delay information and reporting the first delay information to a first core network element is provided, which specifically includes the following steps:

step 21: a terminal (UE) transmits uplink data to a base station; the uplink data may carry UE identifier, session identifier, synchronous receiving group information, data sending time, etc.

Step 22: the base station calculates the air interface time delay (i.e. the first time delay information) according to the received uplink data sent by the UE, for example, the base station may be used as the air interface time delay of the downlink data according to the symmetry of the channel.

The base station compares and analyzes whether the synchronous transmission delay of the user/service reaches the reporting condition according to the obtained air interface delay; wherein, the reporting condition may be at least one of the following: the average value of the transmission delay measurement quantity measured for N1 times is larger than the target transmission delay quantity; the average value of the transmission delay measurement quantities measured for N2 times is larger than the target transmission delay quantity (85% -105% of the target transmission delay quantity) of a preset proportion; the transmission delay measurement quantity of continuous N3 times of measurement is larger than the target transmission delay quantity; the transmission delay measurement quantity measured for N4 times is larger than the target transmission delay quantity of a preset proportion, or other rules and the like; the target transmission delay amount is preconfigured by a first core network element or is determined according to the synchronous transmission strategy; n1, N2, N3, N4 are positive integers. The target transmission delay amount may be an air interface delay amount preconfigured by the first core network element, which may be preconfigured based on a learning algorithm or the like, or may be an air interface delay amount obtained by the first core network element based on a determined synchronous transmission policy or the like.

Step 23: when the base station judges that the condition is met, the air interface time delay can be reported to a first core network element (such as a time delay synchronization function network element). When the reporting condition is not reached, the base station can also report the air interface time delay periodically. The reporting message may carry UE identifier, session identifier, and synchronously receive group information, and the air interface delay value (e.g., may be an air interface delay value that is sent or updated for the first time).

It should be noted that, in the step 22, the determination of the reporting condition is an optional step, that is, the base station may directly report the air interface delay to the first core network element without performing the determination of the reporting condition.

As shown in fig. 3, a flowchart of a terminal measuring first delay information is provided, which specifically includes the following steps:

step 31: the base station sends downlink data to the UE;

step 32: after the downlink data packet of the base station reaches the UE, the UE calculates to obtain the air interface time delay (namely first time delay information) and sends uplink data to the base station; the uplink data packet from the UE to the base station carries the UE identifier, the session identifier, the synchronous receiving group information, the air interface delay value and the like.

Step 33: the base station can compare and analyze whether the synchronous transmission delay of the user/service reaches the reporting condition according to the air interface delay carried in the uplink data packet; or the synchronous transmission delay of the user/service can be compared and analyzed according to the average value of the air interface delay carried in the uplink data packet and the air interface delay measured by the base station, so as to judge whether the synchronous transmission delay of the user/service reaches the reporting condition.

Step 34: when the base station judges that the conditions are met, the air interface time delay (the average value of the air interface time delay carried in the uplink data packet and the air interface time delay obtained by the base station measurement or the air interface time delay carried in the uplink data packet) can be reported to a first core network element (such as a time delay synchronization function network element). When the reporting condition is not reached, the base station can also report the air interface time delay periodically. The reporting message may carry UE identifier, session identifier, synchronous receiving group information, air interface delay value (e.g. may be the first transmitted or updated air interface delay value), etc.

Optionally, under the condition that the base station measures or the terminal measures to obtain the air interface time delay, the base station does not need to judge whether the trigger condition is met, for example, under the condition that the first core network element sends a query message to the base station to obtain the air interface time delay, the base station measures or the terminal measures to obtain the air interface time delay, and then the air interface time delay can be reported to the first core network element by the base station without judging the condition.

Example 1.2: the first core network element sends a first request message to the second core network element, wherein the first request message is used for indicating the base station to send first delay information; the second core network element forwards the first request message to the base station; the base station sends a first message to a second core network element according to the first request message, wherein the first message carries first delay information; and the second core network element forwards the first message to the first core network element.

The manner in which the base station obtains the first delay information is similar to the foregoing example 1.1, and the difference is that the foregoing example 1.1 is that the base station interacts with the first core network element, where the base station interacts with the first core network element through the second core network element, and where repeated, the details are not repeated herein.

Example 2: the first core network element obtains second delay information.

Example 2.1: the first core network element sends a first request message to the second core network element, wherein the first request message is used for indicating a network forwarding node to send second delay information; the second core network element forwards the first request message to the network forwarding node; the network forwarding node sends a first message to a second core network element according to the first request message, wherein the first message carries second delay information; the second core network element forwards the first message to the first core network element.

As shown in fig. 4, taking a second core network element as a session management function network element, and taking a first core network element as a delay synchronization function network element as an example, a process of obtaining second delay information in a subscription manner is described below:

step 41: the session management function network element subscribes to the path delay (i.e., the second delay information, including delay information between the base station and the network forwarding node and/or delay information between different network forwarding nodes) of the user/service to the network forwarding node. The subscription information may carry UE identifier, session identifier, synchronous receiving group information, and subscription mode indication information, for example, the subscription mode may be conditional triggering and/or periodic reporting.

Step 42: the network forwarding node reports or updates the transmission path delay (i.e., the second delay information) of the user/service to the session management function network element. The reporting information can carry reporting or updating mode as conditional triggering or periodic reporting.

Step 43: the session management function network element judges whether the obtained second time delay information needs to be reported or updated to the time delay synchronization function network element. The reporting condition may be at least one of: the average value of the transmission delay measurement quantity measured for N1 times is larger than the target transmission delay quantity; the average value of the transmission delay measurement quantities measured for N2 times is larger than the target transmission delay quantity (85% -105% of the target transmission delay quantity) of a preset proportion; the transmission delay measurement quantity of continuous N3 times of measurement is larger than the target transmission delay quantity; the transmission delay measurement quantity measured for N4 times is larger than the target transmission delay quantity of a preset proportion, or other rules and the like; the target transmission delay amount is preconfigured by a first core network element or is determined according to the synchronous transmission strategy; n1, N2, N3, N4 are positive integers. The target transmission delay amount may be a delay amount of second delay information preconfigured by the first core network element, which may be preconfigured based on a learning algorithm or the like, or may be a delay amount of second delay information obtained by the first core network element based on a determined synchronous transmission policy or the like.

Step 44: when the session management function network element judges that the condition is met, the second time delay information can be reported to the first core network element (such as the time delay synchronization function network element) according to the subscription rule. When the reporting condition is not reached, the session management function network element may also periodically report the second delay information. And reporting a time delay value carrying second time delay information, such as a time delay value from the user/service base station to the PSA section, in the message.

The second delay information may include delay information between the base station and the network forwarding node and/or delay information between different network forwarding nodes, and when the first core network element side determines the synchronous transmission policy according to the second delay information, the delay information determined by the first core network included in the synchronous transmission policy may be in one-to-one correspondence with the second delay information acquired by the first core network element side.

It should be noted that, in the step 43, the judgment for the reporting condition is an optional step, that is, the session management network element may directly report the second delay information to the first core network element without performing the judgment for the reporting condition.

As shown in fig. 5, taking a second core network element as a session management function network element, and taking a first core network element as a delay synchronization function network element as an example, a process of obtaining second delay information by a query manner is described below:

Step 51: the session management function network element queries the network forwarding node for path delays (i.e., second delay information, including delay information between the base station and the network forwarding node and/or delay information between different network forwarding nodes) of the user/service. The inquiry message can carry the UE identifier, the session identifier and the synchronous receiving group information.

Step 52: the network forwarding node reports or updates the transmission path delay (i.e., the second delay information) of the user/service to the session management function network element. The reported message can be provided with the UE identifier, the session identifier, and the numerical values of the group information and the second time delay information.

Step 53: the session management function network element judges whether the obtained second time delay information needs to be reported or updated to the time delay synchronization function network element. The reporting condition may be at least one of: the average value of the transmission delay measurement quantity measured for N1 times is larger than the target transmission delay quantity; the average value of the transmission delay measurement quantities measured for N2 times is larger than the target transmission delay quantity (85% -105% of the target transmission delay quantity) of a preset proportion; the transmission delay measurement quantity of continuous N3 times of measurement is larger than the target transmission delay quantity; the transmission delay measurement quantity measured for N4 times is larger than the target transmission delay quantity of a preset proportion, or other rules and the like; the target transmission delay amount is preconfigured by a first core network element or is determined according to the synchronous transmission strategy; n1, N2, N3, N4 are positive integers. The target transmission delay amount may be a delay amount of second delay information preconfigured by the first core network element, which may be preconfigured based on a learning algorithm or the like, or may be a delay amount of second delay information obtained by the first core network element based on a determined synchronous transmission policy or the like.

Step 54: and when the session management function network element judges that the condition is met, reporting the second time delay information to a first core network element (such as a time delay synchronization function network element). When the reporting condition is not reached, the session management function network element may also periodically report the second delay information. And reporting a time delay value carrying second time delay information, such as a time delay value from the user/service base station to the PSA section, in the message.

It should be noted that, in the step 53, the determination of the reporting condition is an optional step, that is, the session management network element may directly report the second delay information to the first core network element without performing the determination of the reporting condition.

Example 2.2: the first core network element sends a first request message to the network forwarding node, wherein the first request message is used for indicating the network forwarding node to send second delay information; and the network forwarding node sends a first message to the first core network element according to the first request message, wherein the first message carries the second delay information.

Example 2.2 is similar to example 2.1 above, except that example 2.1 above is that the network forwarding node interacts with the first core network element through the second core network element, where the network forwarding node interacts with the first core network element, and where repeated, the details are not repeated here.

Example 3: the first core network element obtains third delay information.

Example 3.1: the first core network element sends a first request message to the second core network element, wherein the first request message is used for indicating a network forwarding node to send third delay information; the second core network element forwards the first request message to the network forwarding node, and the network forwarding node sends the first message to the second core network element according to the first request message, wherein the first message carries third delay information; the second core network element forwards the first message to the first core network element.

As shown in fig. 6, taking the second core network element as a session management function network element, and the first core network element as a delay synchronization function network element as an example, a process of obtaining third delay information by a subscription manner is described below:

step 61: the session management function network element subscribes to third latency information of the data network, such as deterministic network or other network latency, with the network forwarding node (e.g., PSA). The subscription message may carry UE identifier, session identifier, and synchronously receive group information.

Step 62: under the condition that the DN section is a deterministic network or the DN section can ensure the stable transmission delay, calculating the transmission delay (namely third delay information) of the DN section at a network forwarding node (such as PSA) and reporting the transmission delay of the DN section to a session management function network element.

Step 63: the session management function network element judges whether the obtained transmission delay (namely third delay information) of the DN section needs to be reported or updated to the delay synchronization function network element. The reporting condition may be at least one of: the average value of the transmission delay measurement quantity measured for N1 times is larger than the target transmission delay quantity; the average value of the transmission delay measurement quantities measured for N2 times is larger than the target transmission delay quantity (85% -105% of the target transmission delay quantity) of a preset proportion; the transmission delay measurement quantity of continuous N3 times of measurement is larger than the target transmission delay quantity; the transmission delay measurement quantity measured for N4 times is larger than the target transmission delay quantity of a preset proportion, or other rules and the like; the target transmission delay amount is preconfigured by a first core network element or is determined according to the synchronous transmission strategy; n1, N2, N3, N4 are positive integers. The target transmission delay amount may be a delay amount of third delay information preconfigured by the first core network element, which may be preconfigured based on a learning algorithm or the like, or may be a delay amount of third delay information obtained by the first core network element based on a determined synchronous transmission policy, or the like.

Step 64: when the session management function network element judges that the conditions are met, the transmission delay (namely third delay information) of the DN section is reported to the first core network element (such as a delay synchronization function network element). When the reporting condition is not reached, the session management function network element may also periodically report the transmission delay (i.e. the third delay information) of the DN segment. And the reported message carries the time delay value of the third time delay information, namely the time delay value of the DN section of the user/service.

It should be noted that, in the step 63, the determination of the reporting condition is an optional step, that is, the session management network element may directly report the third delay information to the first core network element without performing the determination of the reporting condition.

Example 3.2: the first core network element sends a first request message to the network forwarding node, wherein the first request message is used for indicating the network forwarding node to send third delay information; and the network forwarding node sends a first message to the first core network element according to the first request message, wherein the first message carries third delay information.

Example 3.2 is similar to example 3.1 above, except that example 3.1 is that the network forwarding node interacts with the first core network element through the second core network element, where the network forwarding node interacts with the first core network element, and where repeated, the details are not repeated here.

Example 3.3: the first core network element sends a first request message to the network function entity, wherein the first request message is used for indicating the network function entity to send third delay information; and the network function entity sends a first message to the first core network element according to the first request message, wherein the first message carries third delay information.

As shown in fig. 7, taking a network function entity as AF or NEF, a first core network element as a delay synchronization function element as an example, a procedure of obtaining third delay information by a subscription manner is described as follows:

step 71: the latency synchronization function network element subscribes to third latency information of the data network, such as deterministic network or other network latency, to the AF or NEF. The subscription message may carry UE identifier, session identifier, and synchronously receive group information.

Step 72: AF or NEF calculates transmission time delay (third time delay information) of DN section, and judges whether the obtained transmission time delay (third time delay information) of DN section needs to be reported or updated to network element of time delay synchronization function. The reporting condition may be at least one of: the average value of the transmission delay measurement quantity measured for N1 times is larger than the target transmission delay quantity; the average value of the transmission delay measurement quantities measured for N2 times is larger than the target transmission delay quantity (85% -105% of the target transmission delay quantity) of a preset proportion; the transmission delay measurement quantity of continuous N3 times of measurement is larger than the target transmission delay quantity; the transmission delay measurement quantity measured for N4 times is larger than the target transmission delay quantity of a preset proportion, or other rules and the like; the target transmission delay amount is preconfigured by a first core network element or is determined according to the synchronous transmission strategy; n1, N2, N3, N4 are positive integers. The target transmission delay amount may be a delay amount of third delay information preconfigured by the first core network element, which may be preconfigured based on a learning algorithm or the like, or may be a delay amount of third delay information obtained by the first core network element based on a determined synchronous transmission policy, or the like.

Step 73: and when the AF or NEF judges that the conditions are met, reporting the transmission delay (namely third delay information) of the DN section to a first core network element (such as a delay synchronization function network element). When the reporting condition is not reached, the session management function network element may also periodically report the transmission delay (i.e. the third delay information) of the DN segment. And the reported message carries the time delay value of the third time delay information, namely the time delay value of the DN section of the user/service.

It should be noted that, in the step 72, the determination of the reporting condition is an optional step, that is, the AF or NEF may directly report the third delay information to the first core network element without performing the determination of the reporting condition.

Also for example: the method for indicating the terminal to send the processing capability information by using the second request information and acquiring the processing capability information of the terminal by using the specific first core network element may include:

the first core network element sends a second request message to the terminal through the base station, wherein the second request message is used for indicating the terminal to send the processing capacity information; for example: the first core network element sends second request information to the base station, and the base station sends the second request information to the terminal.

The first core network element receives a second response message sent by the terminal through the base station, wherein the second response message carries the processing capability information of the terminal. For example: and the terminal sends a second response message carrying the processing capability information to the base station, and the base station sends the second response message to the first core network element.

Optionally, the second request message may be a query message or a subscription message, for example, the first core network element sends the query message to the terminal through the base station, and the terminal feeds back the processing delay information of the terminal through the base station according to the query message; or the first core network element may subscribe the transmission delay information to the terminal, and the terminal may trigger reporting the transmission delay information according to the subscribed period or condition, for example, the second request message may carry at least one of the following information: terminal identification information; type information of the terminal; the first indication information is used for indicating a synchronous transmission group where the terminal is located; and the second indication information is used for indicating the sending mode of the target information. The first indication information may be identification information and/or grade information of the synchronous transmission group, and the transmission mode may include periodic transmission or conditional triggering, which is not limited in the embodiment of the present invention.

The following describes the processing capability information of the first core network acquisition terminal in combination with the registration procedure, as shown in fig. 8, specifically including the following steps:

step 81: the UE reports the processing capability information in the registration procedure, and the delay synchronization function network element (i.e. the first core network element) subscribes to the processing capability information of the terminal, for example, the delay synchronization function network element subscribes to the processing capability information of the terminal from the UE data management network element.

Step 82: updating the processing capacity information by the terminal and reporting the updated processing capacity information to the base station; the message for reporting the updated processing capability information may also carry UE type, UE identifier synchronization receiving group information, etc.

Step 83: the base station forwards the updated processing capacity information to the UE data management network element;

Step 85: the network element of the time delay synchronization function judges whether to update the synchronous transmission strategy of the terminal, if so, whether to adjust the transmission time delay of each section, etc.

Step 86 to step 88: specifically, if the radio resource scheduling policy needs to be updated, step 86 is executed, where the message may include information such as UE identification, synchronous receiving group information, and radio scheduling policy. If the forwarding policy of the network forwarding node (i.e. the forwarding policy of the user/service) needs to be updated, executing step 87, and updating the forwarding policy of the user/service to the session management network element by the time delay synchronization function network element, wherein the session management network element issues the forwarding policy to the network forwarding node; or step 88 is executed, the delay synchronization function network element updates the forwarding policy of the user/service to the network forwarding node, where the message may carry the terminal identifier, the session identifier, and update the forwarding policy of the user/service.

and/or the number of the groups of groups,

after the first core network element establishes a synchronous transmission group where the terminal is located according to the third request message, receiving an update message; wherein the update message carries processing capability information updated by the terminal.

In this embodiment, the terminal may send, through the base station, a third request message for establishing the synchronous transmission group to the first core network element; wherein the third request message carries the processing capability information of the terminal. Alternatively, the third request message may be a registration request message, a session establishment request message, or the like. In this way, the first core network element establishes a synchronous transmission group for the terminal according to the third request message, and determines a synchronous transmission policy corresponding to the synchronous transmission group according to the processing capability information, for example, a plurality of terminals included in the synchronous transmission group can synchronously receive data and/or synchronously complete processing of the data based on the synchronous transmission policy.

Further, after the first core network element establishes the synchronous transmission group for the terminal, the terminal may update the processing capability information of the terminal to the first core network element based on the synchronous transmission group information, and then the first core network element may update the synchronous transmission policy according to the processing capability information of the updated terminal.

The following describes the processing capability information obtained by the first core network element with reference to a specific embodiment, as shown in fig. 9, and specifically includes the following steps:

step 91.1: the UE1 sends a request for establishing a synchronous receiving group to the base station, where the request includes the second synchronous receiving group information and the synchronous receiving terminal ID. The second synchronous receiving group information comprises synchronous receiving group identification and/or synchronous receiving group grade information; the synchronous receiving terminal ID may be an ID identifying the user in the network, such as a subscription permanent identity (Subscription Permanent Identifier, SUPI), a subscription encrypted identity (Subscription Concealed Identifier, sui), etc., for identifying the terminals in the group. Wherein the request for establishing the synchronous receiving group can carry the processing capability information of the terminal.

Step 91.2: the base station sends a request for establishing a synchronous receiving group to a synchronous receiving control network element, such as an AMF.

Step 92: the AMF updates UE information to unified data management (Unified Data Management, UDM), including information of UE1 and other UEs in the synchronous reception group, the updated information including second synchronous reception group information, and the like.

Mode 1-step 93.A.1: the AMF returns a synchronous receiving group response message to the base station, wherein the synchronous receiving group response message comprises first synchronous receiving group identification information and an intra-group terminal ID; the first synchronous receiving group and the second synchronous receiving group can be the same or different, and the terminal corresponding to the first synchronous receiving group and the terminal corresponding to the second synchronous receiving group can be the same or different;

Step 93.A.2 and step 93.A.4: the base station respectively sends a response message for establishing a synchronous receiving group and a notification message for establishing the synchronous receiving group to UE1 and UE2 in the group, wherein the messages comprise first synchronous receiving group information;

step 93.A.3 and step 93.A.5: the UE1 and the UE2 respectively feed back a synchronization reception group establishment completion response message to the base station, including a first synchronization reception group identifier, a completion identifier, a terminal identifier, and the like.

Step 93.A.6: the base station sends a response message for establishing the synchronous receiving group to the AMF, wherein the response message comprises a first synchronous receiving group identifier, a completion identifier, a terminal identifier and the like.

Mode 2 differs from mode 1 in that the transmission timing of the set-up synchronization reception notification message for the multi-terminal in the group is different, and mode 2 is that after receiving the set-up synchronization reception group completion response message fed back by UE1, the set-up synchronization reception group notification message is transmitted to UE 2. The AMF sends an establishment response to the initiator UE1 through the base station, and sends an indication of establishing the synchronization reception group to other users in the group.

Step 94: the AMF establishes/updates a synchronous reception group policy to the PCF based on the processing capability information.

It should be noted that the above-mentioned process may be used alone as an implementation process, or may be multiplexed in other processes, such as a service request process, etc., and the embodiment of the present invention is not limited thereto.
