Description

Method, device, storage medium, base station and terminal for transmitting and receiving configuration information

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a storage medium, a base station, and a terminal for sending and receiving configuration information.

Background

With the development of the fifth Generation mobile communication technology (5th-Generation, abbreviated as 5G), the 5G communication system will be gradually deployed and implemented in the future. In a 5G communication system, a 5G Core Network (5G Core Network, abbreviated as 5GC) needs to send much information to a User Equipment (User Equipment, abbreviated as UE). Some of the information may be very large, such as a User Routing Selection Policy (URSP), an Access Network Discovery and Selection Policy (andspc), and the like. Wherein, the URSP and the andsdsp may be collectively referred to as UE Policy (UE Policy, i.e. user equipment Policy).

According to the specification, the 5G core network may transmit the UE Policy to the UE in different Policy segments (Policy sections), where different segments are identified by different Policy Section Identifiers (PSI), but each segment may still be one kilobyte or even longer.

For ease of description, when information is divided into portions, any of the portions may be referred to herein as a "segment.

If the current signal is weak, when transmitting long Non-Access Stratum (NAS) information, the bottom layer may have many retransmission and even retransmission failure situations. Specifically, the larger the NAS information is, the longer the time to transmit the information is, and the lower the success rate is. This can lead to extended or even failed flows (e.g., registration flows).

Taking the URSP as an example, if the REGISTRATION ACCEPT (REGISTRATION ACCEPT) message includes the URSP or the fragment of the URSP, it may cause an extra one kilobyte or even several tens of thousands of kilobytes to be added to the REGISTRATION ACCEPT message, i.e. the size of the REGISTRATION ACCEPT message will be increased greatly. This can result in prolonged registration procedures and even registration failures due to failure of the underlying transport. This situation is particularly evident in weak signals. ANDSP also suffers from the same problem.

On the other hand, when both the Allowed Network Slice Selection auxiliary Information (called Allowed NSSAI for short) of the UE and the UE policy need to be updated, based on the existing specification, there is a high possibility that the UE cannot initiate a service in time. For example, the UE just prepares to initiate a Protocol Data Unit (PDU) session establishment request to the Selected NSSAI (Selected NSSAI, abbreviated as S-NSSAI) 1 according to the URSP, but the network side has deleted S-NSSAI 1 from the allowed NSSAI of the UE, and the PDU session establishment inevitably fails. This may result in waste of UE and network signaling, and affect the UE to correctly initiate the related PDU session establishment procedure in time.

Compared with the prior art, the technical scheme of the embodiment of the invention has the following beneficial effects:

for a network side, an embodiment of the present invention provides a method for sending configuration information, including: acquiring the configuration information, wherein the configuration information comprises at least one piece of relevant information; determining the priority of each piece of relevant information; and transmitting parts of the configuration information in the order of priority from high to low, wherein the parts are selected from the related information. Compared with the existing scheme for sending the configuration information, the scheme of the embodiment of the invention can effectively reduce the size of the message for sending the configuration information in the related flow because the configuration information is sent in batches, is beneficial to quickly finishing the related flow, improves the success rate of sending the configuration information, and ensures that all the related information can be successfully sent to a receiving party (such as user equipment). Further, based on the scheme of this embodiment, when sending the relevant information to the receiving party in batch, the sending party (e.g., the base station on the network side) preferentially sends the relevant information with high priority to the receiving party, which is helpful for the receiving party to quickly obtain the relevant information with high priority, so that the receiving party adjusts its own behavior, so as to quickly initiate a correct relevant service flow.

Further, the sending method further includes: and each time one part is sent, indicating whether the sending of the configuration information is finished or not in the sent part so that the receiving party can adjust the self behavior in time.

Further, the related information includes UE policy and network slice information, and a highest priority part of the configuration information is sent through a management UE policy command message or a registration accept message. Those skilled in the art understand that, by sending the UE policy and the network slice information in batches according to the priorities (e.g., sending the network slice information preferentially and then sending the UE policy), and/or sending part of the content (e.g., a segment with a low priority) in the same related information (e.g., the UE policy) through a subsequent message, or sending the UE policy in batches through the subsequent message as a whole, the scheme of the embodiment can effectively reduce the size of the registration acceptance message, shorten the registration time, and improve the success rate of registration in a weak signal environment.

For the user equipment side, receiving the configuration information, wherein the configuration information comprises at least one piece of relevant information, each part of the configuration information is sent according to the sequence from high priority to low priority, and the part is selected from the relevant information; judging whether the configuration information is received or not every time one part of the configuration information is received; and when the judgment result shows that the configuration information is not completely received, continuously receiving the rest part in the configuration information. Compared with the existing receiving scheme of the configuration information, according to the scheme of the embodiment of the invention, because each part of the configuration information is sent in batches according to the sequence of the priority from high to low, the receiving party (such as user equipment) receives the configuration information in batches, and the receiving party can also adjust the behavior of the receiving party in time by judging whether the configuration information is received completely so as to determine whether to immediately carry out the service.

Further, the receiving method further comprises: in response to receiving an instruction message indicating that configuration information is to be sent in a subsequent message, receiving the configuration information in the subsequent message, the instruction message further indicating an information type of related information included in the configuration information. Therefore, in order to further reduce the size of the message (such as the registration acceptance message), the network side can carry the subsequent indication of sending the configuration information through the message (namely the instruction message at this time), and then send each part of the configuration information in batches from high priority to low priority through one or more subsequent messages. For the user equipment side, the configuration information, the specific receiving opportunity and the receiving mode of the configuration information can be timely obtained according to the instruction message, if the sender sends the information type of the configuration information, the information type of the configuration information can be obtained, the configuration information is received, and the receiver can conveniently and timely adjust the behavior of the receiver.

Further, each part of the configuration information contains indication information indicating whether the configuration information is sent completely; the determining whether the configuration information is received each time a portion of the configuration information is received comprises: and when the received part of the configuration information indicates that the configuration information is not sent completely, continuing to receive the rest part of the configuration information. Therefore, the user equipment can know whether the configuration information is sent completely or not so as to determine whether all parts of the relevant information sent by the sender (such as a base station on the network side) are received completely or not, and therefore the self behavior is optimized more accurately.

Detailed Description

As will be understood by those skilled in the art, as the background art, when the existing 5G core network sends configuration information to a User Equipment (UE), there are still many defects, and there is a great risk of failure in sending the configuration information in a weak signal environment.

The inventor of the present application finds that, this is because when the existing 5G core network sends the relevant information (segment) to the UE, the problem that the relevant information (segment) is too large under weak signals, which causes too long transmission time of the relevant message and even failure, and further causes too long completion time of the procedure and even failure is not considered. On the other hand, when the existing 5G core network sends the relevant information to the UE, the priority of the relevant information of the priority is not considered, which may cause that the UE cannot quickly and timely obtain the relevant service under certain circumstances, for example, the relevant PDU session establishment procedure cannot be timely and correctly initiated. This is more pronounced in weak signals.

In order to solve the foregoing technical problem, an embodiment of the present invention provides a method for sending configuration information, including: acquiring the configuration information, wherein the configuration information comprises at least one piece of relevant information; determining the priority of each piece of relevant information; and transmitting parts of the configuration information in the order of priority from high to low, wherein the parts are selected from the related information.

Those skilled in the art understand that, by adopting the scheme of the embodiment of the present invention, since the configuration information is sent in batch, the size of the message used for sending the configuration information in the related process can be effectively reduced, which is beneficial to quickly completing the related process, improving the success rate of sending the configuration information, and ensuring that all the related information can be successfully sent to the receiving party (such as the user equipment).

Further, based on the scheme of this embodiment, when the sender (e.g., a base station on the network side) sends the relevant information to the receiver in batch, the sender preferentially sends the relevant information with high priority to the receiver, which is helpful for the receiver to quickly obtain the relevant information with high priority, so that the receiver can quickly initiate a correct relevant service flow.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 1 is a flowchart of a method for sending configuration information according to an embodiment of the present invention. The configuration information may include downlink information for a receiving side (also referred to as a receiving side) to perform a relevant procedure. The embodiment may be applied to a network side, for example, performed by a base station of the network side (e.g., a 5G core network), and accordingly, the receiving party may be a user equipment.

Specifically, in this embodiment, the sending method of the configuration information may include the following steps:

step S101, obtaining the configuration information, wherein the configuration information comprises at least one piece of relevant information.

Step S102, the priority of each piece of relevant information is determined.

And step S103, transmitting various parts of the configuration information in the order of priority from high to low, wherein the parts are selected from the related information.

More specifically, the related information may include UE policy, network slice information, and other related information that needs to be sent to the UE. The UE Policy may include a User Routing Selection Policy (URSP), an Access Network Discovery and Selection Policy (Access Network Discovery and Selection Policy, andsdsp); the network slice information may include an allowed NSSAI, a configured NSSAI, and the like, and the allowed NSSAI may be a subset of the configured NSSAI.

Further, a piece of related information may be divided into a plurality of segments, and different segments may be identified by different Policy Segment Identifiers (PSI).

As a non-limiting example, when the configuration information includes a plurality of related information, different related information (or a plurality of segments included in the related information) may correspond to different services. For example, IMS Voice Over IMS (IMS), which is short for IP Multimedia Subsystem (IP Multimedia Subsystem), may correspond to one or more segments of a URSP.

Further, the priority may be embodied between different relevant information of the configuration information. For example, a Policy Control Function (PCF) related service may specify that Allowed Network Slice Selection Assistance Information (Allowed Network Slice Selection Assistance Information, called Allowed NSSAI) has higher priority than the URSP, that is, the Network Slice Information may have higher priority than the UE Policy.

Alternatively, the priority may also be embodied between different segments of the same relevant information.

As a non-limiting example, the priority of the related information and/or segments may be determined according to the related information and/or associated traffic of the segments. For example, for different segments of the URSP, the priority of the URSP segment corresponding to the IMS voice service may be higher than the priority of the URSP segment corresponding to the File Transfer Protocol (FTP) service.

As another non-limiting embodiment, the priority may also be determined according to a user rank associated with the UE as the receiving party. For example, for a gold user configured with a specific Digital Network Name (DNN) or Single Network Slice Selection Assistance Information (S-NSSAI), the priority of configuration Information (e.g., corresponding URSP segments) sent to the UE of the gold user is highest. The gold medal user is a user meeting a preset condition, such as a user with average monthly consumption higher than a preset threshold, a user of a government department, a user of a public safety department, and the like.

As a further non-limiting embodiment, the priority may also be determined according to the access technology to which the UE is currently connected. For example, if the UE currently accesses the network only on the 3GPP access, the priority of the information related to the non-3 GPP access may be reduced. Further, in order for the UE to quickly obtain service, the URSP may be sent to the UE in preference to the ANDSP.

In a typical application scenario, when the UE is in a roaming state, the configuration information and the related information and/or the priority of the segments included in the configuration information may be determined by a pre-negotiation between a Visited Public Land Mobile Network (VPLMN) registered by the UE and a Home Public Land Mobile Network (HPLMN) of the UE.

For example, referring to fig. 2, when configuration information needs to be sent to a UE in a roaming state, the 5G core network may generate appropriate configuration information based on consideration of priority. In this example, the UE policy and the allowed NASSI are specifically set forth as an example, and the 5G core network may further segment the related information included in the configuration information according to needs, so as to reduce the message size when sending the message each time and improve the success rate of sending the message.

Specifically, the VPLMN21 with which the UE is currently registered may perform operation s21 to determine, through negotiation with the HPLMN22 associated with the UE, related information and/or segments included in the configuration information and a prioritization thereof, where the prioritization may include a prioritization between a UE policy and an allowed NSSAI, and, if the UE policy includes multiple segments, a prioritization between the segments. The HPLMN22 associated with the UE may refer to a PLMN to which the UE belongs, and the two may correspond to each other one by one through a Subscription Permanent Identifier (SUPI) of the UE.

Further, the VPLMN21 may perform the operation s21 at any time before sending the configuration information to the UE to complete the negotiation with the HPLMN 22.

Further, the related information and/or segments may be generated from at least one Network Function (NF) and finally combined into the configuration information to be sent to the UE in batch.

As a non-limiting example, the priority of the related information and/or segments may also be determined according to the conventions of different network functions for the related information and/or segments. For example, for a network function there may be no priority requirements for some specific relevant information and/or segments, but specific priority requirements for other relevant information and/or segments. The agreement may be determined according to the related specifications of the existing 3GPP, or may be a customized policy of an operator associated with the UE.

Preferably, the priority of each piece of relevant information and/or segment may be determined according to an indication of the corresponding network function.

In a typical application scenario, after configuring relevant information or segments that need to be sent to the UE, a Policy Control Function (PCF) may send the relevant information and segments to an Access and Management Function (AMF).

Further, the PCF may indicate the priority of each relevant information or segment when sending the relevant information or segment to the AMF.

For example, referring to fig. 3, PCF31 may send the relevant information or segments to AMF32 in batches, and each time a piece of relevant information or segment is sent, it indicates the priority of the piece of relevant information or segment and whether the piece of relevant information or segment is the last piece of relevant information or segment.

Taking the example that PCF31 generates 2 pieces of related information, wherein the related information with higher priority includes 2 segments, PCF31 may perform operations s31 to s33 after generating the related information and segments, so as to send the generated related information and segments to AMF32 in 3 times, and each time the related information or segment is sent, indicate the priority of the related information or segment and whether the related information or segment is the last piece of related information or segment.

As a variation, the number of times of sending the configuration information in batches may also be smaller than the number of related information or segments included in the configuration information, for example, a few smaller segments may be sent in combination to reduce the number of times of sending messages, so as to improve the sending efficiency while ensuring the sending success rate.

In a preferred embodiment, the priority of the relevant information and/or segments is indicated to the next network function or UE in an explicit way. For example, the priority levels between different pieces of relevant information and/or segments may be characterized by the displayed values.

As a variant, the priority of the relevant information and/or segments is indicated to the next network function or UE in an implicit indication. Wherein the implicit indication refers to a time sequence for acquiring the relevant information and/or segments from the corresponding network function.

For example, with continued reference to fig. 3, PCF31 may send the relevant information or fragments to AMF32 sequentially from first to last in time, in order of priority from high to low. That is, the PCF31 in fig. 3 sends the segment with the highest priority among the 2 pieces of related information with the highest priority by performing operation s31, and the PCF31 in fig. 3 sends the related information with the lowest priority among the 2 pieces of related information by performing operation s 33. Further, after receiving the last piece of relevant information or segment sent by the PCF31, the AMF32 may add other relevant information or segments needed to be sent to the UE according to its own needs, and send the relevant information or segments to the UE together with the relevant information or segments transmitted by the PCF31 in order of priority from high to low.

For another example, in the URSP, a URSP segment corresponding to a higher priority service such as an IMS voice service may be preferentially transmitted to the UE before a URSP segment corresponding to an FTP service.

For another example, when both the allowed NSSAI and the URSP of the UE need to be updated and the priority of the allowed NSSAI is higher, the allowed NSSAI may be sent to AMF32 first, so that AMF32 may send the allowed NSSAI to the UE before the URSP.

In one or more alternative embodiments, the AMF32 and PCF31 may be replaced with other Network Functions (NFs).

In one or more embodiments, in step S103, each time a part is sent, whether the sending of the configuration information is completed may be indicated in the sent part, so that the receiving side adjusts its own behavior in time.

Further, the indicating whether the configuration information is sent completely may include: each time a part is transmitted, whether a part to be transmitted exists in the sequence or not is indicated; each transmission of a portion indicates whether the portion is the last portion; indicating that the transmission is finished only in the last transmitted part; whether or not there is a part to be transmitted subsequently is indicated in a part other than the last transmitted part. In practical application, the network may agree with the UE in advance in a suitable indication manner, so that the UE can accurately know the transmission progress of the configuration information.

As a non-limiting example, in step S103, for each piece of relevant information, the relevant information with higher priority is preferentially sent.

Further, when one piece of related information includes a plurality of segments, for each segment in the same piece of related information, the priority of each segment included in the related information may be determined, and a segment with a higher priority may be preferentially transmitted.

For example, referring to fig. 4, after obtaining the configuration information, the 5G core Network 41 sequentially performs operations s41 to s4n to send the configuration information to the UE43 in batch through AN Access Network (AN) 42. Wherein n is more than or equal to 1; the configuration information may include content that is determined by the implementation of the scheme shown in fig. 3, respectively, for a plurality of network functions included in the 5G core network 41; the UE43 accesses the 5G core network 41 through AN 42.

Specifically, the 5G core network 41 may segment and sequentially send the configuration information to the AN42 according to the order of priority from high to low.

Taking as AN example that both the allowed NSSAI and the URSP of the UE need to be updated, when the 5G core network 41 executes the operation s41, the allowed NSSAI may be first sent to the UE43 through the AN42, and then, when the operation s42 is executed, the relevant information of the URSP is sent to the UE43 through the AN 42.

Taking sending only the URSP as an example, the 5G core network 41 may send the URSP segment with the highest priority among the segments of the URSP first when performing the operation s 41. For example, the URSP segment corresponding to the IMS voice service may precede the URSP segment corresponding to the FTP service, and when the configuration information includes both the URSP segment corresponding to the IMS voice service and the URSP segment corresponding to the FTP service, the URSP segment corresponding to the IMS voice service may be preferably sent.

Further, when the operations s41 to s4n are executed, it is indicated whether the related information or segment sent by the current operation is the last related information or segment of the configuration information, so that the UE43 can determine whether the configuration information is received completely.

Further, the highest priority part of the configuration information and other parts may be sent through different messages.

Further, other portions of the configuration information may be sent via one or more messages.

Further, the configuration information sent by the 5G core network 41 in the example shown in fig. 4 may be generated based on the interaction between the AMF32 and the PCF31 shown in fig. 3, and for simplicity, the signaling interaction between the AMF and the PCF is omitted in fig. 4.

In a typical application scenario, referring to fig. 5, based on the scheme of this scenario, the UE53 can complete the registration procedure on the 5G core network 51 quickly.

Specifically, to initiate the Registration procedure, the UE53 may perform operation s51 to send a Registration Request (Registration Request) message. For more details of the present operation, reference may be made to the related specifications of the existing 3GPP, which are not described herein.

Further, in response to the registration request of the UE53, the 5G core network 51 may perform operation s52 to determine the specific content (including relevant information and/or segments and corresponding priorities) of the configuration information that needs to be sent to the UE 53. Further details of the present operation can refer to the related descriptions in fig. 2 and fig. 3, which are not repeated herein.

Further, during the sending of the configuration information, the 5G core network 51 may first perform operation s53, so as to send the related information with the highest priority in the configuration information (or the segment with the highest priority in the related information) to the UE53 through a Registration Accept (Registration Accept) message, and at the same time, indicate that the sending of the configuration information is not completed.

Further, the 5G core network 51 may sequentially perform operations s54 to s5n, so as to sequentially send the remaining unsent related information or segments in the configuration information to the UE53 through subsequent downlink messages in the order of priority from high to low, where n is greater than or equal to 4, and each time one related information or segment is sent, it indicates whether the configuration information is sent completely.

For example, the registration accept message may include a partial URSP segment and indicate that the remaining URSP segments and other related information will pass through subsequent messages. The subsequent message may be a management UE Policy Command (management UE Policy Command).

For simplicity, the related messages (uplink information) sent by the UE53 to the 5G core network 51 are omitted in fig. 5. For example, a Manage UE Policy Complete (Manage UE Policy Complete) message or a Manage UE Policy Reject (Manage UE Policy Reject) message corresponding to the Manage UE Policy command message.

Further, in this scenario, messages sent to the UE53 may all be unvarnished by the AN52 to which it has access.

As a variation, if the registration accept message indicates that the configuration information has been sent, the operations s54 to s5n may be omitted.

In one or more alternative embodiments, the configuration information and the information type of the related information included in the configuration information may be indicated by an instruction message, and then the step S103 is performed to transmit the parts of the configuration information in batches by the subsequent message.

Therefore, in order to further reduce the size of the message (such as the registration acceptance message), the network side can carry an indication that the configuration information is to be sent subsequently through the instruction message, and then send each part of the configuration information in batches according to the sequence of the priority from high to low through one or more subsequent messages.

For example, with continued reference to fig. 5, when the 5G core network 51 performs the operation s53, the registration accept message sent may not contain any content of the configuration information (i.e. does not include any relevant information and/or segments), but only indicates that there is information to be sent subsequently, and may indicate the type of information (e.g. UE policy). Then, the 5G core network 51 may continue to execute the steps s54 to s5n, and send the parts of the configuration information in batches according to the priority order from high to low through subsequent messages. That is, the 5G core network 51 only indicates in the registration accept message that the configuration information will be sent subsequently, and the relevant information and/or segments included in the configuration information are all sent to the UE53 in batches in the subsequent downlink message in sequence from the highest priority to the lowest priority.

As will be understood by those skilled in the art, in the application scenario, since the size of the registration acceptance message is reduced, the registration acceptance message can be transmitted more quickly on an air interface, and the possibility of transmission failure is also reduced, the registration time can be effectively shortened, and the registration success rate can be improved.

In another exemplary application scenario, referring to fig. 6, based on the scheme of this scenario, a network (e.g., the 5G core network 61) may implement the update of the configuration information of the UE63 more efficiently. The configuration information may include UE policies such as URSP.

Specifically, when it is determined that there is a UE policy that needs to be updated to the UE63, the 5G core network 61 may perform operation s61 to determine the specific content and corresponding priority of the configuration information. Wherein the related information may be a UE policy, the UE policy including at least one segment.

Further, after establishing a Non-Access Stratum (NAS) connection with the UE3 and entering a CM-CONNECTED (CM-CONNECTED) state, the 5G core network 61 may perform operation s62, so as to send the UE policy or segment with the highest priority in the configuration information to the UE63 first through a UE policy management command, and carry therein an indication of whether the UE policy or segment is the last UE policy or segment.

If the configuration information is sent once in operation s62, the process is ended.

Otherwise, the 5G core network 61 continues to perform operations s63 to s6n, so as to sequentially send the remaining UE policies and/or segments in the configuration information to the UEs 63 in batches according to the order of priority from high to low through a plurality of management UE policy command messages, and indicate whether the configuration information is sent completely at each sending.

For simplicity, the management UE policy complete message or the management UE policy reject message replied by the UE63 and received after each management UE policy command message is sent is omitted in fig. 6.

As a variation, the UE policy or segment sent by the 5G core network 61 may be transmitted via AN 62.

As a non-limiting example, when the configuration information is indicated to be not completely sent, the information type of the subsequently sent part may be further indicated. Preferably, the indication of the type of information is used to allow the receiver to which the configuration information is directed to adjust its own behavior.

For example, when there are multiple URSP segments to be sent to the UE and the UE needs to initiate a Protocol Data Unit (PDU) session, based on the scheme of this embodiment, the UE may choose to initiate a PDU session after all the URSP segments have been received, so as to implement optimal selection.

For another example, if it is indicated that the subsequent ANDSP needs to receive, the UE may choose to initiate a related procedure on the non-3 GPP access after receiving the ANDSP.

As a Non-limiting example, the network may send the configuration information to the UE in different manners, for example, the configuration information may be sent through a Non Access Stratum (NAS) message. Alternatively, the 5G core Network may first send the configuration information to AN Access Network (Access Network, abbreviated AS AN), and then the AN sends the configuration information to the UE AS AN Access Stratum (AS) message. Alternatively, the network may employ an Over-the-Air Technology (OTA) mode, such as sending to the UE via Short Messaging Service (SMS).

In yet another exemplary application scenario, referring to fig. 7, a network (e.g., 5G core network 71) may simultaneously update the UE 73's network slice information and UE policies. In this scenario, the UE73 may be in a Mobile Initiated Connection Only (MICO) mode (that is, a mode in which Only the UE73 initiates a Connection), or may be in other modes such as a normal mode.

Specifically, in this application scenario, the UE73 registers successfully on the 5G core network 71, and after obtaining the allowed network slice information such as NSSAI configured by the 5G core network 71 and the UE policy such as URSP, returns to a Connected Management IDLE (CM-IDLE) state and enters the MICO mode.

Assume that the allowed NASSI currently received by the UE73 is {1,2,3,4}, and that application 1 is specified in the received URSP to initiate a PDU session preferentially on S-NSSAI ═ 1, and secondly can initiate a PDU session on S-NSSAI ═ 2.

Then, due to the change of subscription information of the UE71, the change of the user identity of the UE71 (for example, the UE73 is an internet of things type, and the owner changes from a company a to a company B), and the like, the 5G core network 71 changes the network slice information such as the allowed NSSAI of the UE73, and for example, the updated allowed NSSAI is {2,4}, that is, {1,3} is deleted. This means that the UE73 will not be able to initiate PDU session setup on the allowed NSSAI {1,3 }.

However, since the UE73 is in the MICO mode and CM-IDLE state at this time, the 5G core network 71 cannot page the UE73, but can only wait for the next time the UE73 actively accesses to send the updated allowed network slice information to the UE 73.

Thereafter, the 5G core network 71 may also update the UE policy, such as the URSP of the UE71, due to the subscription information change of the UE73, the adjustment of the operator policy, and the like.

Thus, if the relevant information that needs to be updated to the UE73 includes two types of relevant information, i.e., the allowed NSSAI and the URSP, according to the scheme of this embodiment, it may be determined that the priority of the allowed NSSAI is higher than that of the URSP.

After the UE73 actively initiates a connection to the 5G core network 71 and establishes a NAS connection with the 5G core network 71, the 5G core network 71 may perform operation s71 to preferentially send the updated allowed NSSAI {2,4} to the UE 73.

Thus, the UE73 may select an appropriate S-NSSAI for application 1 based on the updated allowed NSSAI and the existing URSP-related information. At this time, since S-NSSAI ═ 1 is no longer present in the updated allowed NSSAI list, the UE73 may perform operation S72 to select S-NSSAI ═ 2 to initiate the PDU session establishment procedure.

Further, the 5G core network 71 may perform operation s73 to accept the PDU session setup request of the UE 73.

Further, the 5G core network 71 may perform operation s74 to send the updated UE policy of the URSP or the like to the UE 73. Specifically, if the URSP includes a plurality of segments, the segments may be sent to the UE73 in batches in order of priority from high to low according to the priority of each segment.

Further, in this scenario, the signaling interaction between the 5G core network 71 and the UE73 may be relayed through AN Access Network (AN) 72.

For simplicity, related uplink messages, such as uplink information fed back by the UE corresponding to each management UE policy command message (e.g., a management UE policy complete message or a management UE policy reject message), are omitted in fig. 7.

Those skilled in the art will understand that, if the UE policy such as URSP and the allowed network slice information such as NSSAI are not defined in the priority and transmission order based on the existing specification, it is very likely that the operation s74 is performed first, and then the operation s71 is performed. If so, because the execution time of the operation S74 may be relatively long (e.g., due to too large UE policy information, weak signal, etc.), during which if the UE73 initiates PDU session establishment for application 1, the UE73 may select S-NSSAI as 1 for PDU session establishment because the updated allowed NSSAI is not obtained. In practice, S-NSSAI ═ 1 has been deleted from the allowed NSSAI list of the UE73 on the network side, so the 5G core network 71 would reject the PDU session setup request of the UE73, resulting in a PDU session setup failure.

Based on the scheme of this embodiment, since the priority of the allowed network slice information such as NSSAI is higher than the priority of the UE policy, it is ensured that the UE73 can receive the updated network slice information preferentially, thereby effectively reducing the possibility of PDU session failure establishment.

Therefore, by adopting the scheme of this embodiment, when the sender (e.g., 5G core network) sends the relevant information to the receiver in batch, the sender preferentially sends the relevant information with high priority or sends the relevant information with high priority to the receiver in segments, which is helpful for the receiver to quickly obtain the relevant information with high priority, so that the receiver can adjust its own behavior and quickly initiate a correct relevant service flow. Further, each time a part is sent, whether the sending of the configuration information is finished is indicated, so that a receiver can adjust own behavior in time.

Specifically, when determining the specific content of the configuration information, the network prioritizes the related information therein; and if the related information needs to be segmented, performing priority sequencing on each segment. Further, when the related information or the segments are interacted between different network functions, priority needs to be considered and a priority indication needs to be sent to the other party. Further, when the core network sends the configuration information to the UE, the core network sends the configuration information in an order from high priority to low priority. During transmission, if the same piece of related information includes multiple segments, the network needs to indicate whether all the segments are completely transmitted by the UE. Further, the network may indicate in the current message whether other messages need to be received subsequently, and may also notify the specific received message type. Further, the UE may determine whether to continue to receive the configuration information and the specific type of the received information subsequently according to the indication in the received message, so as to optimize its own behavior.

Fig. 8 is a schematic structural diagram of a device for sending configuration information according to an embodiment of the present invention. Those skilled in the art understand that the sending apparatus 8 for configuration information (hereinafter, referred to as the sending apparatus 8) according to this embodiment is used to implement the method technical solutions described in the embodiments shown in fig. 1 to fig. 7.

Further, the related information may include at least one segment, and the sending device 8 may further include: the second determination module 83 determines, for each piece of relevant information, the priority of the segments comprised by said relevant information.

Further, the related information and/or segments may be generated from at least one network function, and the priority of each related information and/or segment may be determined according to an indication of the corresponding network function.

Further, the indication of the network function may be an explicit indication or an implicit indication, where the implicit indication may refer to a chronological order in which the relevant information and/or segments are obtained from the corresponding network function.

Further, before transmitting the parts of the configuration information in the order of priority from high to low, the transmitting module 84 may further indicate, through an instruction message, that the configuration information is to be transmitted in a subsequent message, and an information type of related information included in the configuration information.

Further, the sending device 8 may further include: the indicating module 85 indicates whether the configuration information is sent in the sent part every time one part is sent.

Further, the indicating whether the configuration information is sent completely may include: each time a part is transmitted, whether a part to be transmitted exists in the sequence or not is indicated; each transmission of a portion indicates whether the portion is the last portion; indicating that the transmission is finished only in the last transmitted part; whether or not there is a part to be transmitted subsequently is indicated in a part other than the last transmitted part.

Further, when indicating that the configuration information is not completely transmitted, the indication module 85 may further indicate an information type of a subsequently transmitted portion.

Preferably, the indication of the type of information is used to allow the receiver to which the configuration information is directed to adjust its own behavior.

Further, the related information may include UE policy and network slice information, the network slice information may include allowed network slice information (i.e., allowed NSSAI), and the highest priority part of the configuration information may be sent through a management UE policy command message or a registration accept message.

For more contents of the operation principle and the operation manner of the sending apparatus 8, reference may be made to the related description in fig. 1 to fig. 7, which is not repeated herein.

Fig. 9 is a flowchart of a method for receiving configuration information according to an embodiment of the present invention. The configuration information may be sent by using the method in the embodiments shown in fig. 1 to fig. 7. The embodiment may be applied to a user equipment side, for example, executed by a user equipment, and accordingly, the sender of the configuration information may be a network, for example, a base station on the network side.

Specifically, in this embodiment, the method for receiving the configuration information may include the following steps:

step S901, receiving the configuration information, where the configuration information includes at least one piece of related information, where each part of the configuration information is sent in an order from high priority to low priority, and the part is selected from the related information.

Step S902, determining whether the configuration information is received every time a part of the configuration information is received.

And when the judgment result of the step S902 indicates that the configuration information is not received completely, executing step S903, and continuing to receive the remaining part of the configuration information.

More specifically, the explanation of the terms in the present embodiment can refer to the related descriptions in fig. 1 to fig. 7, which are not repeated herein.

Further, the sending of the parts of the configuration information in order from high priority to low priority may refer to: for each piece of the related information, the related information having a higher priority is transmitted with priority.

Further, the related information may include at least one segment, the portion may be further selected from the segments, and the transmitting of the portions of the configuration information in the order of priority from high to low may further refer to: for each segment in the same correlation information, the higher priority segment is transmitted preferentially.

Further, the priority of the related information and/or the segments may be determined according to the traffic associated with the related information and/or the receiving party (i.e., UE) receiving the configuration information.

Further, the indication of the network function may be an explicit indication or an implicit indication, where the implicit indication may refer to a chronological order of obtaining the relevant information and/or segments from the corresponding network function.

Further, the portion of the configuration information having the highest priority may be received through a different message from other portions. Wherein, the part with the highest priority is the configuration information received by the UE first.

For example, in the scenario corresponding to fig. 5 described above, the UE may first receive the URSP segment with the highest priority in the URSPs based on the registration accept message, and then continue to receive the remaining URSP segments of the URSP in subsequent downlink messages according to the indication of the registration accept message.

Further, other portions of the configuration information may be received via one or more messages.

For example, in the scenario corresponding to fig. 6, the UE may receive different portions of the configuration information from multiple UE policy management command messages in sequence.

Further, in response to receiving an instruction message indicating that configuration information is to be sent in a subsequent message, the UE may receive the configuration information in the subsequent message, the instruction message also indicating an information type of related information included in the configuration information.

For example, in a scenario shown in the alternative embodiment corresponding to fig. 5, the UE may first obtain, from the registration accept message, an indication that the 5G core network will send the configuration information later, and then receive, in a subsequent message, each part of the configuration information based on the indication.

Further, each part of the configuration information may include indication information indicating whether the configuration information is sent completely.

Accordingly, in step S902 and step S903, when the received part of the configuration information indicates that the configuration information is not completely transmitted, the remaining part of the configuration information may be continuously received.

For the user equipment side, the specific receiving opportunity and receiving mode of the configuration information required to be received can be timely obtained according to the instruction message, if the sender sends the information type of the configuration information, the information type of the configuration information can also be obtained, and the configuration information is received, so that the receiver can timely adjust the behavior of the receiver.

Further, the indicating that the configuration information is not sent completely may include: the received portion indicates that there is no subsequent portion to send; the received portion indicates the relevant information or segmentation as the last portion; when the sender of the configuration information indicates that the sending is finished only in the last sent part, the received part comprises the indication; when the transmitting side indicates whether there is a part to be transmitted subsequently in a part other than the last transmitted part, the received part does not include the indication. The UE may determine whether the configuration information is received based on the indications.

Further, the network may also indicate whether the configuration information is sent while sending the portion. Correspondingly, the receiving method of this embodiment may further include the steps of: when the received portion further indicates an information type of a remaining portion of the configuration information, adjusting a behavior of itself according to the information type.

For example, when the UE needs to initiate a PDU session and the received segments indicate that the URSP segments need to be received subsequently, based on the scheme of this embodiment, the UE may choose to initiate the PDU session after all the URSP segments are received, so as to achieve the optimal selection.

For another example, if the received indication indicates that an ANDSP needs to be received subsequently, the UE may choose to initiate a related procedure on the non-3 GPP access after receiving the ANDSP.

Further, the related information may include UE policy and network slice information, and the first received related information or segment may be received through a policy UE policy command message or a registration accept message.

For example, in the scenario corresponding to fig. 7 described above, when a PDU session establishment needs to be initiated, the UE may determine an appropriate S-NSSAI based on the updated allowed NSSAI received earlier, so as to improve the success rate of the PDU session establishment.

Thus, with the solution of this embodiment, since the parts of the configuration information are sent in batch according to the order of priority from high to low, the receiving party (e.g. the user equipment) receives the configuration information in batch, and while receiving each part, the receiving party can also adjust its own behavior in time by judging whether the configuration information is received completely, so as to determine whether to immediately perform the service.

Further, based on the solution of this embodiment, the UE may further know whether the configuration information is sent completely, so as to determine whether all parts of the related information sent by the sender (e.g., the base station on the network side) have been received completely, thereby optimizing its behavior more accurately.

Further, the portion of the configuration information having the highest priority may be received through a different message from other portions.

Correspondingly, when the judgment result of the judging module 92 indicates that the received part of the configuration information indicates that the configuration information is not completely sent, the second receiving module 93 continues to receive the remaining part of the configuration information.

Further, the indicating that the configuration information is not sent completely may include: the received portion indicates that there is no subsequent portion to send; the received portion indicates the relevant information or segmentation as the last portion; when the sender of the configuration information indicates that the sending is finished only in the last sent part, the received part comprises the indication; when the transmitting side indicates whether there is a part to be transmitted subsequently in a part other than the last transmitted part, the received part does not include the indication.

Further, the receiving device 9 may further include: an adjusting module 94, when the received portion further indicates the information type of the remaining portion of the configuration information, adjusting the behavior of itself according to the information type.
