Changes can be made to the function and arrangement of the discussed elements without departing from the spirit and scope of the present disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For example, the described method may be performed in an order different from that described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

In the short message delivery process of related technologies, the high reliability of important short messages cannot usually be guaranteed when they are delivered. For example, important short messages (such as AO verification codes) in short message systems/communication networks usually cannot be guaranteed to be delivered first, and it is difficult to meet business requirements. For another example, when the short message system/communication network is overloaded, important short messages cannot be distinguished, and there is a risk of traffic control.

The reason for the above-mentioned problems in the delivery of short messages is that the network only provides user priority, service priority (such as call priority over short message) and message priority (such as response message priority over request message) in related technologies. In flow control, etc. In the scenario, it is ensured that the services of high-priority users, high-priority service requests, and high-priority messages are processed. For the same short message service, there is usually no priority in the network, so the transmission reliability of a specific short message cannot be guaranteed.

In order to solve at least one of the above problems, the embodiments of the present disclosure provide a method for processing short messages based on slicing. By enhancing the slicing mechanism in the related art, differentiated processing of short messages with different priorities can be realized. In related technologies, slices are usually used to isolate conversational services, and different slices are selected for services according to the different needs of conversational services, and related technologies do not support isolation of control plane services. The embodiment of the present disclosure binds slicing and non-conversational services, and can map important short message requirements with slicing capabilities, thereby realizing flow control and priority processing of important short messages, and ensuring the transmission reliability and transmission reliability of important short messages in the SMSONAS solution. real-time.

Referring to FIG. 1, a slice-based short message processing method provided by an embodiment of the present disclosure, when applied to the SMSC side, includes:

Step 11. When the SMSC sends a short message to the first terminal, it determines the first priority of the short message, and sends a request message for the called route of the first terminal to the UDM to which the first terminal belongs, the request message Carry the first priority information of the short message.

Here, after the SMSC receives the MT type short message to be sent to the first terminal from the short message center, it may first determine the priority of the short message (assuming that the final priority of the short message is the first priority), and then, Then query the route of the first terminal from the UDM to which the first terminal belongs, and when querying the route, the indication information of the first priority will be carried so that the UDM knows the priority of the short message.

Specifically, the SMSC may determine the first priority of the short message according to one or more of the following methods:

a) Determine the first priority of the short message according to whether the office direction of the short message is a preset service platform. For example, when the short message is a verification code short message (delivered to the banking service platform bureau) sent by the bank, it can be determined that the short message has a preset high priority. In the embodiments of the present disclosure, the short message can be divided into several priority levels as required, for example, divided into three priority levels, namely high priority, medium priority and low priority.

b) Determine the first priority of the short message according to the contract information of the short message service of the second terminal, wherein the second terminal is the calling terminal that sends the short message. For example, when the sending terminal of the short message is a terminal of a signed high-priority short message, it may be determined that the short message has a certain preset high priority.

c) Extracting content keywords of the short message, and determining the first priority of the short message according to whether the content keywords belong to a preset list.

Step 12: The SMSC receives the address of the first SMSF in the first type slice returned by the UDM, where the first SMSF is the first type of service that the UDM serves the first terminal according to the first priority. Selected from the SMSF, the first type of SMSF is an SMSF of the first type of slice that supports the short message service of the first priority, and the first type of slice is bound to the short message service of the first priority Slices.

Here, the embodiment of the present disclosure pre-establishes a binding relationship between different SMS priorities and different types of slices. In the binding relationship, a slice corresponding to a higher SMS priority has a lower delay and/or Or higher transmission reliability. In this way, in step 12, the UDM can select an SMSF from the SMSF serving the first terminal and located in the first type slice according to the first priority of the short message, as the first SMSF, and assign the first SMSF to the first SMSF. The SMSC is notified of the address of an SMS in the first type slice.

Step 13. The SMSC invokes the service of the first SMSF according to the address of the first SMSF in the first type slice, and delivers the short message in the first type slice through the first SMSF.

Here, the SMSC can invoke the service of the first SMSF according to the address of the first SMSF in the first type slice, and then invoke the MT reachable service of AMF and the N1/N2 message transparent transmission service through the first SMSF, and The short message is sent to the second terminal.

Through the above steps, the embodiment of the present disclosure implements a slice-based short message delivery process. Since slice resources with different processing performance correspond to different short message priorities, different priority short messages can be processed differently, and the number of important short messages can be reduced. The time delay in short message processing reduces the probability of important short messages being flow-controlled when the network load is high, and improves the transmission reliability of important short messages.

Please refer to Figure 2 below, which shows the flow of the slice-based short message processing method when applied to the UDM side, including:

Step 21: The UDM receives a called route request message for the first terminal sent by the SMSC, where the request message carries the first priority information of the short message to be sent to the first terminal.

Here, when the SMSC needs to send a short message to the first terminal, it will send a called route request message to the UDM, requesting to obtain the routing information of the first terminal. In the embodiment of the present disclosure, the request message carries the message to be sent to the The first priority information of the short message of the first terminal.

Step 22: UDM selects the first SMSF from the first type of SMSF serving the first terminal, and sends the address of the first SMSF in the first type slice to the SMSC, where the first SMSF The class SMSF is an SMSF supporting the short message service of the first priority in the first type slice, and the first type slice is a slice bound to the short message service of the first priority.

Here, the UDM selects the first SMSF from the pre-stored first type SMSF serving the first terminal, and sends the address of the first SMSF in the first type slice to the SMSC.

Through the above steps, the embodiment of the present disclosure realizes the priority of UDM based on short message, selects the SMSF in the corresponding slice to provide the short message delivery service, and realizes the short message delivery process based on the slice, because the slice resources with different processing performance correspond to different The priority of the short message, which can realize the differentiated processing of different priority short messages, and improve the transmission reliability of important short messages.

Before step 21 above, the UDM may also receive an address registration request sent by the first SMSF after being selected as the SMSF of the SMSF of the first priority of the first terminal. The address registration request carries the The address of the first SMSF in the first type of slice, the first SMSF supports the short message service processing capability of the first terminal of the first priority, and the correspondence between the first priority and the first type of slice; then, UDM According to the address registration request, the first type SMSF serving the first terminal is stored, that is, the first SMSF is stored in the first type SMSF serving the first terminal.

Of course, the UDM may also receive other address registration requests sent by other SMSFs other than the first SMSF, and the other SMSF may also be the SMSF selected as the short message service of the first priority of the first terminal. When there are multiple SMSFs in the first type of SMSF serving the first terminal, UDM can randomly select one of the SMSFs as the first SMSF, and can also select the most loaded SMSF first based on the current load and processing capacity of each SMSF. The SMSF with light weight or the highest processing capability is used as the first SMSF, which is not specifically limited in the embodiment of the present disclosure.

Please refer to Figure 3 below, which shows the flow of the slice-based short message processing method when applied to the AMF side, including:

Step 31: The AMF receives a short message registration request sent by the first terminal. The short message registration request carries information that the first terminal supports the first type of slice, and the first type of slice is of the first priority. The slice bound to the SMS service.

Step 32: The AMF configures the binding relationship between the first type slice and the first priority short message service, and selects the SMSF in the first type slice for the first priority short message service (assumed to be the first SMSF), And send the short message service activation request of the first terminal to the first SMSF.

The AMF may select an SMSF that provides services for the first terminal, and instruct the first SMSF to register an address with the UDM through the short message service activation request.

Step 33: After receiving the short message service activation response returned by the first SMSF, the AMF sends a registration acceptance response message to the first terminal.

Here, after the first SMSF successfully registers the address with the UDM, it will return a short message service activation response to the AMF. After receiving the above response, the AMF sends a registration acceptance response message to the first terminal.

Subsequently, after the AMF receives the MT reachable service invocation request for the first terminal sent by the first SMSF, it may use the first type slice to respond to the MT reachable service invocation request; and, after receiving the first After the message transparent transmission service call request for the short message of the first priority of the first terminal sent by the SMSF, the short message is sent to the first terminal by using the first type slice.

Through the above steps, the embodiment of the present disclosure implements a slice-based short message delivery process. Since slice resources with different processing performance correspond to different short message priorities, differentiated processing of short messages with different priorities can be realized.

Please refer to Figure 4 below, which shows the flow of the slice-based short message processing method when applied to the first SMSF side, including:

Step 41: The first SMSF receives a short message service activation request sent by the AMF. The short message service activation request indicates that the first SMSF is selected as the SMSF of the first priority short message service of the first terminal.

Here, when the AMF selects the first SMSF to provide a service for the first priority short message service of the first terminal, the AMF will send the above short message service activation request to the first SMSF.

Step 42: The first SMSF sends an address registration request to UDM according to the SMS service activation request. The address registration request carries the address of the first SMSF in the first type slice, and the first SMSF supports the first terminal's The short message service processing capability of the first priority, and the corresponding relationship between the first priority and the first type of slice.

Here, the first SMSF registers its address in the first type slice with the UDM through the SMS service activation request, so that the UDM can store the first SMSF in the first type SMSF serving the first terminal.

Subsequently, after the above-mentioned first SMSF receives the short message of the first priority to the first terminal forwarded by the SMSC, the first SMSF may call the service of AMF and deliver the short message to the first type slice in the first type of slice. The first terminal implements a slice-based short message delivery process. Since slice resources with different processing performance correspond to different short message priorities, different priority short messages can be processed differently.

In the slice-based short message processing flow in the embodiment of the present disclosure, the first terminal needs to perform short message registration with the AMF. The first terminal first obtains a service routing policy, where the service routing policy includes a binding relationship between the short message service of the first priority and the first type of slice. Specifically, the first terminal may obtain the foregoing service routing policy from a policy control function entity (PCF). Then, the first terminal sends a short message registration request to AMF. The short message registration request carries information that the first terminal supports the first type of slice, and the first type of slice is the short message service of the first priority. The bound slice.

The processing steps of each entity are described above. The following will further explain the above slice-based short message processing flow through an example of interaction between various entities.

Please refer to Figure 5, which shows an example of interaction during SMS service registration, specifically:

From 501 to 503, the UE obtains the service routing strategy from the network (such as the PCF), and binds the high-priority short message service with the specific slice type according to the strategy. When the UE registers with the AMF SMS, it carries the slice type that can support the high-priority SMS service.

504 ~ 505, AMF needs to configure the correspondence between high-priority SMS and slice types, and select the SMSF in the low-latency and high-reliability slice for the high-priority SMS service during registration, and send an SMS service activation request to the selected SMSF .

506~509, after SMSF receives the above SMS service activation request, when registering its address in UDM, it carries the correspondence between high priority SMS support capability and slice type, UDM stores the corresponding information, and SMSF receives the SMS returned by UDM After the service activation response, the registration acceptance response is returned to the UE.

Please refer to Figure 6, which shows an example of interaction when sending a short message, specifically:

601. When the SMSC sends a short message to a user, the SMSC processes the short message, and determines a high-priority short message according to a specific condition (the specific condition can be preset or stored in the user's short message subscription data).

Specifically, the above-mentioned specific condition may be that the source of the message is the banking service platform office direction, and the SMSC determines the important short message according to the source of the message, and determines the priority of the short message. The specific condition is that the receiving user is a user applying for a low-latency short message service, and the SMSC determines important short messages based on the user's short message subscription and user number. The specific condition can also be a keyword of the content of the short message, and the SMSC determines the important short message based on the keyword.

From 602 to 603, when the SMSC initiates a called route query to the UDM to which the user belongs or invokes the UDM service to select the called short message route, it carries high priority short message indication information in the corresponding message. The UDM returns the SMSF address in the corresponding slice according to the indicated and stored SMSF capabilities and the slice type.

From 604 to 610, the SMSC invokes the SMSF service to forward the high-priority short message to the SMSF according to the returned SMSF address, and the SMSF refers to the relevant process to deliver it in the slice.

The above embodiments describe in detail the short message processing method based on slices. The embodiment of the present disclosure also provides a short message processing method based on the short message priority identification, which can also realize the differentiated processing of different priority short messages. This process will be described in detail below.

In the short message processing method based on the short message priority identification, the embodiment of the present disclosure introduces the short message priority. In the short message MT process, the short message priority identification is used to realize the differentiated processing of different short messages. For example, the flow control and priority of important short messages can be realized. Processing to ensure the reliability and real-time transmission of important short messages in the SMSONAS solution.

Please refer to Figure 7, which shows the flow of the short message processing method based on the short message priority identifier when applied to the SMSC side, including:

Step 71: When the SMSC sends a short message to the first terminal, it determines the first priority of the short message, and sends a request message for the called route of the first terminal to the UDM to which the first terminal belongs, the request message Carry the first priority information of the short message.

Here, the information of the first priority of the short message carried in the request message may specifically be the first priority, or an identifier of the first priority (for example, indicating high priority, medium priority, or low priority). Level identification).

Step 72: The SMSC receives the address of the second SMSF returned by the UDM, where the second SMSF is selected by the UDM from the second type of SMSF serving the first terminal according to the first priority. The second type of SMSF is an SMSF supporting the short message service of the first priority.

Here, when there are multiple SMSFs in the second type of SMSF serving the first terminal, UDM can randomly select one of the SMSFs as the second SMSF, and can also preferentially select according to information such as the current load and processing capacity of each SMSF The SMSF with the lightest load or the highest processing capability is used as the second SMSF, which is not specifically limited in the embodiment of the present disclosure.

Step 73: The SMSC invokes the service of the second SMSF according to the address of the second SMSF, and sends the short message to the first terminal through the second SMSF. Priority information.

Here, the SMSC is sending a call request to the second SMSF to deliver the short message to the first terminal through the second SMSF. Specifically, the call request carries the first priority of the short message , Thereby causing the second SMSF to perform adaptive processing according to the first priority.

Through the above steps, the embodiments of the present disclosure realize that according to the priority of the short message, the corresponding SMSF is selected to provide the priority-based short message delivery service, so that the differentiated processing of the short message of different priority levels can be realized, and the transmission reliability of the important short message can be improved.

Please refer to Figure 8, which shows the flow of the SMS processing method based on SMS priority identification when applied to the UDM side, including:

Step 81: The UDM receives a called route request message for the first terminal sent by the SMSC, where the request message carries the first priority information of the short message to be sent to the first terminal.

Step 82: UDM selects a second SMSF from the second type of SMSF serving the first terminal, and sends the address of the second SMSF to the SMSC, where the second type of SMSF supports all types of SMSFs. The SMSF of the short message service of the first priority.

Here, the UDM selects the second SMSF from the pre-stored second SMSF serving the first terminal, and sends the address of the second SMSF to the SMSC.

Through the above steps, the embodiment of the present disclosure realizes the priority of UDM based on short message, selects the corresponding SMSF to provide short message delivery service, and realizes the short message delivery process, which can realize the differentiated processing of different priority short messages and improve the transmission of important short messages. reliability.

Before the above step 81, the UDM may also receive an address registration request sent by the second SMSF after being selected as the SMSF of the first priority SMSF of the first terminal, and the address registration request carries the The address of the second SMSF, and the second SMSF supports the short message service processing capability of the first terminal with the first priority; then, the UDM may store the second SMSF service for the first terminal according to the address registration request Type SMSF, that is, store the second SMSF in the second type SMSF serving the first terminal.

Of course, the UDM may also receive other address registration requests sent by other SMSFs other than the second SMSF, and the other SMSF may also be the SMSF selected as the short message service of the first priority of the first terminal. When there are multiple SMSFs in the second type of SMSF serving the first terminal, UDM can randomly select one of the SMSFs as the second SMSF, and can also select the most loaded SMSF according to the current load and processing capacity of each SMSF. The SMSF with light weight or the highest processing capability is used as the second SMSF, which is not specifically limited in the embodiment of the present disclosure.

Please refer to Figure 9, which shows the flow of the SMS processing method based on SMS priority when applied to the AMF side, including:

Step 91: The AMF receives the MT reachable service invocation request for the first terminal sent by the second SMSF, where the second SMSF is one of the second type SMSFs of the first terminal, and the second type SMSF is For the SMSF supporting the short message service of the first priority, the MT reachable service invocation request carries the first priority information of the short message to be sent to the first terminal.

Step 92: The AMF performs priority paging processing on the MT reachable service invocation request according to the first priority.

Here, the AMF may perform priority paging processing on the MT reachable service invocation request according to the first priority. Specifically, when the priority of the first priority is higher, the higher reliability and lower priority are performed. Delay processing, and when the priority of the first priority is lower, the processing with lower reliability and higher delay is executed. Specific processing methods include flow control processing when the system load is high. The short message service with a higher priority has a relatively low probability of being flow controlled, while the short message service with a lower priority has a relatively high probability of being flow controlled. For another example, different message queue queuing strategies can also be adopted for call requests of different priority levels. SMS services with higher priority levels can be inserted at the head or front of the message queue, and SMS services with lower priority levels can follow Time sequence is queued in the message queue.

Step 93: The AMF receives a message transparent transmission service invocation request for the short message sent by the second SMSF, where the message transparent transmission service invocation request carries information of the first priority of the short message.

Step 94: The AMF preferentially delivers the short message to the first terminal according to the first priority.

Similarly, when the short message is preferentially delivered to the first terminal according to the first priority, the above-mentioned processing means may also be used.

Through the above steps, the embodiments of the present disclosure can implement differentiated processing of short messages with different priorities, and improve the transmission reliability of important short messages.

Before step 91, the AMF may also receive a short message registration request sent by the first terminal. After receiving the short message registration request, when the AMF determines that the first terminal needs to configure an SMSF supporting the first priority short message service, Select the SMSF (assuming the second SMSF) that supports the short message service of the first priority for the first terminal, and send the first terminal's short message service activation request to the second SMSF; subsequently, the AMF receives After the short message service activation response returned by the second SMSF, a response message of registration acceptance is sent to the first terminal.

Please refer to Figure 10, which shows the flow of the SMS processing method based on SMS priority when applied to the second SMSF side, including:

Step 101: The second SMSF receives the short message of the first priority forwarded by the SMSC to the first terminal and the information of the first priority of the short message. The second SMSF is the second type of SMSF of the first terminal. In one of the SMSFs, the second type of SMSF is an SMSF supporting the short message service of the first priority.

Step 102: The second SMSF invokes the service of the AMF, and sends the short message to the first terminal through the AMF, wherein, when the service of the AMF is invoked, the second SMSF transfers the service of the first priority The information is sent to the AMF, and carries the information of the first priority of the short message so that the AMF performs corresponding priority processing according to the first priority.

Specifically, for the manner in which the AFM performs priority processing according to the first priority, reference may be made to the above description, and details are not described herein again.

Before step 101, if the second SMSF receives a short message service activation request sent by AMF, the short message service activation request indicates that the second SMSF is selected as the SMSF of the first priority short message service of the first terminal; At this time, the second SMSF may send an address registration request to UDM according to the short message service activation request. The address registration request carries the address of the second SMSF, and the second SMSF supports the first terminal's first terminal. A priority SMS service processing capability.

The processing steps of each entity are described above. In the following, an example of interaction between various entities will be used to further explain the above SMS processing flow based on SMS priority.

Refer to Figure 11, which shows an example of interaction during SMSF service registration, specifically:

111. When the SMSF registers with the NRF for service, it also registers its ability to support high-priority short messages, that is, carries information about the priority of the short messages it supports in the registration request.

112. The NRF records the message priority information that the SMSF can support, and returns a service registration response to the SMSF.

Please refer to Figure 12, which shows an example of interaction during SMS service registration, specifically:

121. When a UE (such as a 5G user) attaches, it sends a registration request to the network (AMF).

122~125, AMF selects an SMSF for the UE. Specifically, the AMF obtains the UE’s short message service subscription information, and determines the UE’s SMS priority according to the UE’s short message service subscription information. In this example, it is assumed that the UE is a high priority. SMS UE, so AMF will decide to select SMSF supporting high-priority SMS for the user. AMF can select an SMSF that can support the SMSF priority of the UE from multiple SMSFs through local configuration or a service discovery mechanism, and send an SMS service activation request to the selected SMSF.

Here, when the SMSF is selected through the service discovery mechanism, the AMF needs to instruct to select the SMSF supporting high-priority short messages when invoking the service discovery mechanism, and the NRF supports identifying the indication and selecting the SMSF that supports high-priority short messages.

126-128, SMSF registers its address to UDM according to the SMS service activation request sent by AMF. When registering the SMSF address to UDM, it will carry the ability to support SMS priority processing. The UDM receives the registration request and stores the capability, and returns a short message service activation response to the AMF. After receiving the above response, the AMF returns a registration acceptance response to the UE.

Please refer to Figure 13, which shows an example of interaction when sending a short message, specifically:

1301. When the SMSC sends a high-priority MT short message to a user, the SMSC processes the short message, and determines the high-priority short message according to a specific condition (the specific condition can be preset or stored in the user's short message subscription data).

1302~1303, when the SMSC initiates a called route query to the user's home UDM or invokes the UDM service to select the called short message route, it carries a high priority short message identifier. UDM selects the appropriate SMSF according to the high-priority short message identification and the stored SMSF to support the short message priority processing capability, and returns the SMSF address that supports the short message priority processing to the SMSC.

1304. The SMSC calls the SMSF service according to the returned SMSF address to forward the high-priority short message to the SMSF, carrying the high-priority short message identifier.

From 1305 to 1307, SMSF calls AMF's Namf_MT EnableUEReachability service to carry the high-priority SMS identification of the short message to be sent. AMF performs priority processing on the N2 interface according to the high-priority short-message identification. If the user is idle, AMF treats the user according to the high-priority short-message identification. Carry out priority paging.

From 1308 to 1310, SMSF calls AMF's Namf_Communication N1N2Message Transfer service, which carries the high-priority short message identifier of the short message to be sent, and AMF processes the high-priority short message identifier on the N1 interface according to the high-priority short message identifier. If flow control is not allowed, high priority short messages are sent first. AMF can also superimpose the SMS priority in the business priority, further supporting the priority of high-priority SMS to be higher than that of other services or other SMS.

The short message processing methods based on slice and based on SMS priority are described above respectively. The equipment for implementing the above method will be further provided below.
