The present application relates to the field of wireless communication technologies, and particularly to a method Short Message service (SMS) over Non Access Stratum (NAS) support capability of a User Equipment (UE), an Access and Mobility Management Function (AMF) and UE.
In terms of SMS over NAS support capability management, for the SMS over NAS support capability, the UE during registration carries the SMS requested IE (SMS requested Information Element; IE: Information Element), of which the values are as shown in Table 1 and which is used to inform the network of the UE's capability to support the SMS. The AMF determines whether the UE subscribes to the SMS service according to the subscription information obtained from the UDM (Unified Data Management), and if so, the AMF selects and activates the SMSF, and the SMSF further registers to the UDM and subscribes to the change in SMS-related subscription information. So far, both the AMF and the SMSF have created the UE context and recorded the SMS-related information, and the UDM has also recorded the address of the SMSF and the access type available for the SMS. The SMSF returns an activation success response to the AMF, and then the AMF records the SMSF address in the UE context and carries the SMS allowed IE (SMS allowed Information Element) in the registration acceptance message. The values of the SMS allowed IE are as shown in Table 1, indicating the support capability of the SMS over NAS after network negotiation.
Step 301: a UE carries the SMS requested IE during registration to inform the network of the UE's capability to support the SMS.
Step 302: as in the conventional registration procedure, if the AMF relocation occurs, the old AMF notifies a new AMF of the SMSF address as a part of the UE context.
Step 303: when the SMS requested is carried in the registration request, the AMF determines whether the UE subscribes to the SMS service according to the subscription information obtained from the UDM, and if so, the AMF selects the SMSF.
Steps 304-305: the registration procedure is completed, and the AMF activates the SMS service of the user through the Nsmsf_SMService_Activate service operation provided by the SMSF, which includes AMF address, Access Type, GPSI (Generic Public Subscription Identifier) (if available) and SUPI (Subscription Permanent Identifier) information.
Step 306: the SMSF discovers the UDM and interacts with it.
Steps 307a-307b: the SMSF records or updates the UE context including the user subscription information and the AMF address. The SMSF registers to the UDM through the Nudm_UECM_Registration (UE context management registration service; CM: Context Management), and the SMSF obtains the user's SMS subscription information from the UDM through the Nudm_SDM_Get (user subscription data acquisition service; SDM: Subscriber Data Management) and subscribes to the notification on changes in subscription information.
Step 308: the SMSF returns a response to the AMF, and the AMF records the SMSF address in the UE context.
Step 309: the AMF carries the SMS allowed in the registration accept message, indicating the support of the SMS over NAS after network negotiation.
If the UE triggers, the AMF triggers or the UDM triggers (by subscription) removing the support of the SMS over NAS support capability, there is a need for the AMF and the SMSF to trigger deleting the UE context in the SMSF and the SMSF address in the UDM respectively.
In the transmission of short messages, for the SMS MO, the UE in the IDLE state firstly establishes a connection through the SR (Service Request) procedure, and then sends the SMS through the NAS UL Transport message; and the UE in the CONNECTED state sends the SMS directly through the NAS UL Transport message.
For the SMS MT, the SMSF in the IDLE state triggers the AMF to page the UE through the Namf_MT_EnableUEReachability (enable user reachability service) service. After success, the SMSF triggers the AMF to forward the SMS through the Namf_Communication_N1N2MessageTransfer (N1/N2 message forwarding service), and the AMF selects the RAT (Radio Access Technology) (3GPP or non-3GPP) according to the operator's policy when sending the DL NAS Transport message. In the case of UE unreachability, the AMF discards the message directly and does not return a transmission success message, and then the SC (Service Center) will re-initiate the SMS MT after receiving the prompt that the UE is reachable.
The disadvantage in the prior art is: how to update the SMS over NAS support capability on the network side has not been given. For example, if the SMS deregistration is initiated by the NW (network), the UE is not notified at this time, and the UE may make a wrong SMS MO attempt during this procedure.

The accompanying drawings illustrated here are used to provide the further understanding of the present application and constitute a part of the present application, and the schematic embodiments of the present application and the illustration thereof are used to explain the present application but not limit the present application improperly. In the accompanying drawings.
The inventor noticed in the inventive process: the 3GPP R15 5GS (5G System) defines the support for SMS over NAS, including the support for SMS over NAS between the UE and AMF through 3GPP/non-3GPP, the selection of the AMF for the SMSF, the inspection of the SMSF for subscription data, and the transmission of the MO/MT SMS. The specific procedure includes the registration and deregistration of the SMS over NAS support capability to support the SMS over NAS support capability negotiation, the SMS MO procedure and the SMS MT procedure between the UE and the network. However, the procedure of triggering the SMS over NAS support capability update on the network side is not described in the current standards. Therefore, the embodiments of the present application propose a solution for updating the SMS over NAS support capability, and the SMS over NAS support capability update may also be triggered and implemented by the network side.
The embodiments of the present application will be illustrated below in combination with the drawings. In the illustration process, the behaviors of other entities (e.g., SMSF, UE, etc.) will be involved, but such illustration does not mean they must implement in cooperation or must implement alone. Actually, when they implement separately, they also solve the problems at their own sides respectively, but when they are used in combination, the better technical effect may be obtained.
In the embodiments, the AMF may be the AMF in the 5G architecture, or may include another network element that can implement the same function, where the network element may be a logical entity network element or a physical entity network element.
The short message function may be the SMSF in the 5G architecture, or may include another network element that can implement the same function, where the network element may be a logical entity network element or a physical entity network element.
The user data management function may be the UDM in the 5G architecture, or may include another network element that can implement the same function, where the network element may be a logical entity network element or a physical entity network element.
The configuration update procedure may be the Configuration Update in the 5G architecture, or other procedures that can implement the same function.
The SMS over NAS support capability may also be called the SMS over NAS support capability or short message support capability. The SMS over NAS support capability in the embodiments of the present application refers to the SMS over NAS support capability, that is, the SMS over NAS support capability. The short message sending procedure may also be called the SMS MO procedure.
In order to facilitate understanding and implementation, the embodiments of the specific AMF, SMSF, UDM, and Configuration Update are also given in the embodiments, but this does not mean that the implementation can only be made by them.
Step 401: the AMF receives a triggering condition of the SMS function/user data management function, and/or, the AMF determines that the SMS over NAS support capability update needs to be triggered.
Step 402: the AMF updates the SMS over NAS support capability of a UE.
Correspondingly, the SMS over NAS support capability update scheme of the UE is further provided in an embodiment of the present application as follows.
Step 501: the UE receives the SMS over NAS support capability update triggered by an AMF, where the SMS over NAS support capability update is triggered by the AMF when receiving a triggering condition of the short message function/user data management function and/or determining that the SMS over NAS support capability update needs to be triggered.
Step 502: updating the SMS over NAS support capability of the UE according to the requirement of the AMF. That is, the UE updates the SMS over NAS support capability of the UE according to the SMS over NAS support capability update triggered by the AMF.
Specifically, for example, in the scheme of triggering the SMS over NAS support capability update at the network side, when the AMF receives the trigger condition of the short message function/user data management function or the AMF determines by itself that the SMS over NAS support capability update needs to be triggered, the AMF triggers, through the configuration update procedure, the UE to initiate the registration update procedure, or the AMF directly updates the record of the UE through the configuration update procedure, or the AMF performs update of the relevant data of the UE in the corresponding procedure, and the corresponding procedure includes a procedure related to the short message service or short message transmission. That is, in an implementation, the AMF updates the SMS over NAS support capability of the UE, including at least one of:
In an implementation, the AMF determines that the SMS over NAS support capability update needs to be triggered when at least one of following conditions occurs:
In the technical solution provided by the embodiments of the present application, when the AMF receives the trigger condition of the short message function or the user data management function, and/or the AMF determines that the SMS over NAS support capability update needs to be triggered, the AMF updates the SMS over NAS support capability of the UE. The update of the SMS over NAS support capability can be triggered by the network side, thereby avoiding the UE from making a wrong attempt to send short messages.
The application will be illustrated below by way of examples.
In this embodiment, the SMSF is triggered by the AMF to perform the update of the UE context related to the SMS over NAS; the AMF updates the SMS over NAS support capability of the UE through the configuration update procedure, and the updated indication information of the SMS over NAS is carried to indicate the UE to re-register; and after UE returns the configuration update complete, the UE initiates a registration update procedure to re-negotiate the SMS over NAS support capability with the network, and complete the update of the SMS over NAS in this procedure.
Specifically, triggering through the configuration update the UE to initiate the registration update procedure to update the SMS over NAS support capability may include:
In a specific implementation, the method may further include carrying an indication of SMS over NAS in the configuration update procedure.
It is assumed that the network triggers the change in SMS over NAS support capability due to the change in operator configuration. For example, the AMF judges and decides to change the original SMS over NAS allowed via both 3GPP access and non-3GPP access to the SMS over NAS allowed via 3GPP access only.
Step 601: the AMF determines that the original SMS over NAS needs to be updated, for example, changing from the SMS over NAS allowed via both 3GPP access and non-3GPP access to the SMS over NAS allowed via 3GPP access only.
Part A:
Steps 602-603: AMF triggers the SMSF to perform the update of the UE context related to the SMS over NAS.
Part B:
Step 604: the AMF updates, through the configuration update procedure, the SMS over NAS support capability of the UE, and the updated indication information of the SMS over NAS is carried, the AMF indicates the UE to re-register, and the AMF may further indicate the UE to return a response message after completing the update.
Step 605: the UE returns the configuration update complete to the AMF.
Step 606: the UE initiates a registration update procedure to re-negotiate the SMS over NAS support capability with the network immediately after returning the configuration update complete. The update of the SMS over NAS is completed in this procedure.
The process of parts A and B can be in no particular order, or A first and then B, or B first and then A.
In this embodiment, the AMF triggers deleting the information related to the UE SMS over NAS in the SMSF, and the SMSF triggers deleting the SMSF address in the UDM. The AMF, through the configuration update procedure, updates the SMS over NAS support capability of UE, and the updated indication Information of the SMS over NAS is carried; and after receiving the response returned by the UE, the AMF updates the SMS over NAS recorded in the AMF to the updated support condition.
Specifically, updating, through the configuration update, the SMS over NAS support capability of the UE may include carrying the indication information of updating the SMS over NAS in the configuration update procedure.
It is assumed that the network triggers the change in SMS over NAS support capability due to the change in operator configuration. For example, the AMF judges and decides to change the original SMS over NAS allowed via both 3GPP access and non-3GPP access to the SMS over NAS not allowed. The AMF may also make a decision directly or indirectly through the change in the subscription data obtained from the UDM, for example, the user cancels the SMS subscription. The AMF is also possible to make a decision according to the policy information of the user, for example, the user cannot send short messages in arrears. The AMF is also possible to make a decision according to the change in the relevant information obtained through the SMSF.
Step 701: the AMF determines that the original SMS over NAS needs to be updated, for example, changing from the SMS over NAS allowed via both 3GPP access and non-3GPP access to the SMS over NAS not allowed. The AMF may also make a decision directly or indirectly through the change in the subscription data obtained from the UDM, for example, the user cancels the SMS subscription. The AMF is also possible to make a decision according to the policy information of the user, for example, the user cannot send short messages in arrears. The AMF is also possible to make a decision according to the change in the relevant information obtained through the SMSF.
Part A:
Steps 702-704: the AMF triggers deleting the information related to the UE SMS over NAS (including UE context and AMF address) in the SMSF, and the SMSF triggers deleting the SMSF address in the UDM.
Part B:
Step 705: the AMF, through the configuration update procedure, updates the SMS over NAS support capability of the UE, and the updated indication information of the SMS over NAS is carried, and the AMF may further indicate the UE to return a response message after completing the update.
Step 706: the AMF updates the SMS over NAS recorded in the AMF to the updated support condition after receiving the response returned by the UE.
The processes of parts A and B can be in no particular order, or A first and then B, or B first and then A. If the AMF does not require the UE to return a response when updating the NAS over SMS, the relevant records in the UE context in the AMF can be updated after the configuration update command message is successfully sent, that is, after step 705.
In this embodiment, the AMF triggers the SMSF to perform the update of the UE context related to the SMS over NAS. The AMF carries an indication of the updated SMS over NAS in the deregistration accept message sent to the UE, and completes the update of the local UE context.
Specifically, updating the SMS over NAS support capability of the UE in a corresponding procedure, includes carrying an indication of SMS over NAS in a deregistration procedure; or, carrying an indication of SMS over NAS in a response message of a service request.
In an implementation, an SMS Allowed IE or an MM cause is carried in the response message of the service request to indicate a change in the SMS over NAS support capability.
It is assumed that the network triggers the change in SMS over NAS support capability due to the change in operator configuration. For example, the AMF judges and decides to change the original SMS over NAS allowed via both 3GPP access and non-3GPP access to the SMS over NAS allowed via 3GPP access only. The AMF may make a decision according to the deregistration procedure of non-3GPP (access type) performed currently by the UE, and then update the SMS over NAS information recorded in the AMF, update the UE context of the SMSF, and carry the indication of the updated SMS over NAS in the deregistration accept message returned to the UE.
Step 801: the UE triggers the non-3GPP deregistration procedure, so the AMF judges and decides to change the original SMS over NAS from SMS over NAS allowed via both 3GPP access and non-3GPP access to SMS over NAS allowed via 3GPP access only.
Steps 802-803: the AMF triggers the SMSF to perform the update of the UE context related to the SMS over NAS.
Step 804: the AMF carries an indication of the updated SMS over NAS in the deregistration accept message sent to the UE, and performs the update of the local UE context.
In this embodiment, the AMF carries the indication of the updated SMS over NAS in the SMS MO procedure and performs the update of the local UE context.
Specifically, updating the SMS over NAS support capability of the UE in a corresponding procedure, includes carrying an indication of SMS over NAS in an SMS sending procedure.
In an implementation, in the SMS sending procedure, the indication of SMS over NAS is carried in the CP Ack returned by the SMSF; or the indication of SMS over NAS is determined and returned directly by the AMF to the UE.
It is assumed that the network triggers the change in SMS over NAS support capability due to the change in operator configuration. For example, the AMF judges and decides to change the original SMS over NAS allowed via both 3GPP access and non-3GPP access to the SMS over NAS not allowed. The AMF local, SMSF, and UDM have completed the relevant updates. When the UE initiates the SMS MO procedure, the indication of the updated SMS over NAS is carried in the response message returned to the UE.
Step 901: for the UE in the CM-IDLE state, the response message to establish the N1 connection in the SR may carry the SMS Allowed IE or carry the MM cause to indicate the changed SMS over NAS support capability.
Step 902: for the UE in the CM-IDLE or CM-Connected state, the indication of SMS over NAS may be carried in the response returned after receiving the request to send the SMS MO message, where this indication may be carried in the CP Ack returned by the SMSF or may be determined and returned directly by the AMF to the UE before informing the SMSF to forward, and the parameter carried may be the SMS Allowed IE or MM cause to indicate the changed SMS over NAS support capability.
The embodiments of the present application further provide a mobile management function, a UE, and apparatuses for updating the SMS over NAS support capability. Since the principle solving the problem of these devices is similar to that of the methods for updating the SMS over NAS support capability, the implementations of these devices can refer to the implementations of the methods, and the repeated description thereof will be omitted here.
