[0149] In order to better understand the technical solutions of the present application, the following is first introduced:

[0150] Dualsteer

[0151] Dualsteer, i.e. multi-access technology, allows a UE to access two networks simultaneously. The Dualsteer device is a device that supports traffic control and user data switching (for different services) across two 3GPP access networks; it can be a single UE if no data is transmitted between the two networks at the same time; it can be two separate UEs if data is transmitted between the two networks at the same time. In addition, the Dualsteer device has two subscriptions / SUPIs, sharing one subscription profile from the same operator. In the present application file, the terminal will be described taking the above Dualsteer device as an example.

[0152] In the present application file, ASP refers to Access Selection Policy, which refers to a policy applied to the Dualsteer device, for example, applied to the Dualsteer terminal enablement layer. The ASP can be used for the Dualsteer device to perform data transmission, for example, for the Dualsteer device to determine to select the access mode corresponding to SUPI-1 to send data 1, and select the access mode corresponding to SUPI-2 to send data 2. The access mode here can be understood as a type of access, for example, 3GPP access, Non-3GPP access; it can also be understood as a transmission resource of a certain access mode, for example, a protocol data network (Protocol Data Network, PDN) connection, an evolved packet system (Evolved Packet System, EPS) bearer, a protocol data unit (Protocol Data Unit, PDU) session, a quality of service (Quality of Service, QoS) flow, etc. The ASP can be a new UE policy, or an enhanced UE route selection policy (UE Route Selection Policy, URSP). In an implementation, the ASP can include the following information:

[0153] Each ASP rule has a Traffic descriptor (TD): to identify the application traffic. The format and values can be the same as in the TD in URSP rules. Then, under each Traffic descriptor, it includes:

[0154] (1) Rule precedence: UE evaluates the ASP rules according to the rule precedence.

[0155] (2) Public Land Mobile Network (PLMN) selection preference and Radio Access Technology (RAT) preference for access: indicates the PLMN ID and RAT type through which the application traffic should be transmitted by 3GPP access. This entry can have one or more values, and the UE needs to select one of them (no priority list).

[0156] (3) Core Network (CN) preference: indicates the preferred CN type to handle the access.

[0157] (4) Access selection verification criteria: indicates the restrictions for the ASP. Unless all the provided verification criteria are met, the ASP will not be considered valid.

[0158] Problem 1: How does UDM associate the two SUPIs of Dualsteer device

[0159] In the existing disclosed technology, how does UDM associate the Dualsteer device, which can be achieved by:

[0160] (1) UDM based on local configuration;

[0161] (2) Dualsteer pairing ID;

[0162] (3) SUPI 1 UE context contains SUPI 2 value;

[0163] (4) The association of the UE using SUPI 1 and the UE using SUPI 2 is completed in UDM through the Dualsteer association ID;

[0164] (5) AMF 2 also includes Dualsteer capability and Dualsteer pairing information (sent to UDM);

[0165] In the above solutions, additional signaling overhead is required for Dualsteer devices, and there is room for optimization.

[0166] Problem 2: SUPI exposure problem of ASP

[0167] ASP is used for Dualsteer device selection data transmission path, for example: traffic 1 uses SUPI1 transmission, traffic 2 uses SUPI2 transmission. Since SUPI information is not allowed to be transmitted over the air, the association between SUPI and traffic needs to be defined in ASP so that the Dualsteer terminal can select the transmission path according to the traffic characteristics. In the prior art, it is disclosed that primary SUPI and secondary SUPI can be defined in ASP to obscure the real SUPI information, for example:

[0168] One SUPI is marked as primary SUPI and the other SUPI is marked as secondary SUPI, so that asymmetric policies can be provided to each SUPI and differentiated processing is performed according to the policies.

[0169] However, this scheme requires the UE to indicate to the network side whether it is a primary SUPI or a secondary SUPI, which consumes certain signaling; at the same time, if the access mode of the terminal changes, it is not clear how to define the primary SUPI and the secondary SUPI. Therefore, how the network side determines the policy corresponding to the SUPI needs to be optimized.

[0170] Problem 3: UE context synchronization problem

[0171] In the prior art, UDM can determine that SUPI-1 and SUPI-2 come from the same UE, or determine that SUPI-1 and SUPI-2 have an association, which mainly depends on the registration of SUPI-2 in the network. However, the network element serving SUPI-1 is not clear whether the UE is performing Dualsteer service.

[0172] This can cause the problem of UE context synchronization in the network. For example, the Dualsteer device establishes PDU session-1 through SUPI-1 and PDU session-2 through SUPI-2. In the prior art, AMF-2 and SMF-2 serving SUPI-2 can obtain the corresponding terminal context, that is, whether the UE is performing Dualsteer service or whether the UE is authorized Dualsteer service. At this time, the UE can switch the traffic of PDU session-2 to PDU session-1. However, since AMF-1 and SMF-1 serving SUPI-1 do not know whether the UE is performing Dualsteer service, the problem of inconsistent understanding between the network and the terminal is caused.

[0173] The information processing method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0174] Referring to FIG. 2, an information processing method is provided in the embodiments of the present application, and an execution subject of the method is a first network side node. In the present application, a node can represent an object in different forms such as a device, a function, a subsystem, and the like. Optionally, the first network side node can be a UDM device. In the present application, the first network side node is taken as a UDM device for example, and it can be understood that the type of the first network side node is not limited to the UDM device.

[0175] The method comprises the following steps.

[0176] Step 201: The first network side node performs at least one of a first operation and a second operation according to first information.

[0177] The first operation comprises determining at least one of the following.

[0178] (1) The first SUPI and the second SUPI are used by the same terminal.

[0179] (2) The first SUPI and the second SUPI are associated.

[0180] The first operation is mainly used to determine that the first SUPI and the second SUPI are associated according to a first PEI and a second PEI, that is, to realize the association of the first SUPI and the second SUPI based on the first PEI and the second PEI at the network side. It can be understood that the prior art already supports the terminal to optionally carry a PEI in the registration process, and therefore the first operation can be performed without the terminal sending additional signaling for configuration or indication, thereby saving signaling overhead.

[0181] It can be understood that in an actual application scenario, the first network side node can also determine that the first SUPI and the second SUPI are not used by the same terminal or the first SUPI and the second SUPI are not associated according to the first PEI and the second PEI, that is, to determine that the first SUPI and the second SUPI are not associated by the first PEI and the second PEI.

[0182] The second operation comprises at least one of the following.

[0183] (1) Determining second information.

[0184] (2) Sending the second information.

[0185] (3) Updating third information.

[0186] The first information includes at least one of the following: information indicating registration of the first SUPI, which can be a registration request sent by the terminal in the first SUPI registration process, or a registration message (such as Nudm_UECM_Registration) sent by the AMF based on the registration request sent by the terminal in the first SUPI registration process; information indicating that the terminal enables Dualsteer; information indicating that the terminal supports Dualsteer; information indicating registration of the second SUPI, which can be a registration request sent by the terminal in the second SUPI registration process, or a registration message (such as Nudm_UECM_Registration) sent by the AMF based on the registration request sent by the terminal in the second SUPI registration process; the first PEI; and the second PEI.

[0187] The second information is used for at least one of the following: performing data transmission; selecting a path for data transmission; selecting a connection for data transmission; selecting a SUPI for data transmission; selecting a modem for data transmission; authorization of a data transmission mode (allowing or not allowing the first SUPI and the second SUPI to be transmitted simultaneously); and confirming that the Dualsteer function is available or unavailable.

[0188] The third information includes at least one of the following: terminal subscription information; data set information; AM context information; SM context information; and the second information.

[0189] The terminal can also be referred to as a Dualsteer device.

[0190] In the embodiments of the present application, the first network side node determines at least one of the following based on the first PEI and the second PEI: the first SUPI and the second SUPI are used by the same terminal; the first SUPI and the second SUPI are associated, which realizes association of the first SUPI and the second SUPI without generating additional signaling overhead; and the first network side node performs determination of the second information, which is used for: performing data transmission; selecting a path for data transmission; selecting a connection for data transmission; selecting a SUPI for data transmission; selecting a modem for data transmission; authorization of a data transmission mode; and confirming that the Dualsteer function is available or unavailable, thereby solving the problem of indicating identity information by the terminal to the network, avoiding exposure of the SUPI of the terminal on the air interface, and saving signaling overhead.

[0191] In an optional embodiment, before the first network node performs at least one of the first operation and the second operation, the method further includes:

[0192] The first network side node obtains the first information.

[0193] In an optional implementation, in a case where the first information comprises the first PEI and the second PEI,

[0194] The determining, according to the first information, that the first SUPI is used by the same terminal as the second SUPI comprises:

[0195] In a case where it is determined that the first PEI and the second PEI have an association, it is determined that the first SUPI is used by the same terminal as the second SUPI; and / or,

[0196] The determining, according to the first information, that the first SUPI has an association with the second SUPI comprises:

[0197] In a case where it is determined that the first PEI and the second PEI have an association, it is determined that the first SUPI has an association with the second SUPI.

[0198] In the embodiments of the present application, in a case where the first network side node determines that the first PEI and the second PEI have an association, it is further determined that the first SUPI is used by the same terminal as the second SUPI, or the first SUPI has an association with the second SUPI.

[0199] The above-mentioned first PEI and the second PEI having an association can include that the first PEI and the second PEI are the same, for example, the terminal specifically being a dual-card device, wherein two cards correspond to the first PEI and the second PEI respectively, and the PEIs of the two cards are the same; or can also include that the first PEI and the second PEI are not the same, for example, the terminal specifically being a dual-card device, wherein two cards correspond to the first PEI and the second PEI respectively, and the PEIs of the two cards are not the same. The determination manner of the first PEI and the second PEI having an association can adopt an existing non-standardized determination manner, for example, the association relationship of the first PEI and the second PEI can be determined through online handling, network management configuration, short message handling, business hall handling, etc. On the other hand, after determining the association relationship of the first PEI and the second PEI, the association relationship of the first PEI and the second PEI can be locally configured in the first network side node, that is, in some implementations, the first network side node can learn the association relationship of the first PEI and the second PEI through local configuration. The specific determination manner of the first PEI and the second PEI having an association is not limited in the embodiments of the present application, as long as the implementation means capable of determining that the first PEI and the second PEI have an association can be applied to the technical solution of the present application.

[0200] In an optional implementation, the first SUPI has an association with the second SUPI, comprising:

[0201] The first SUPI and the second SUPI are used to perform Dualsteer.

[0202] In an optional implementation, in a case that the first information comprises the first PEI and the second PEI, the first network-side node acquires the first information, comprising:

[0203] The first network-side node receives the first PEI and the second PEI from the terminal.

[0204] In the embodiments of the present application, the first PEI and the second PEI are specifically provided by the terminal to the first network-side node.

[0205] In an optional implementation, the first network-side node receives the first PEI from the terminal, comprising:

[0206] The first network-side node receives the first PEI from the terminal through a connection corresponding to the first SUPI;

[0207] The first network-side node receives the second PEI from the terminal, comprising:

[0208] The first network-side node receives the second PEI from the terminal through a connection corresponding to the second SUPI.

[0209] In the embodiments of the present application, the first PEI and the second PEI are specifically sent by the terminal to the first network-side node through a connection corresponding to the first SUPI and the second SUPI respectively, for example, the first PEI is carried in a registration request message in the process of the terminal registering the first SUPI, and is sent to the first network-side node through a connection corresponding to the first SUPI (which may comprise a first AMF corresponding to the first SUPI); the second PEI is carried in a registration request message in the process of the terminal registering the second SUPI, and is sent to the first network-side node through a connection corresponding to the second SUPI (which may comprise a second AMF corresponding to the second SUPI).

[0210] In an optional implementation, the second information is information for distinguishing the first SUPI and the second SUPI;

[0211] Optionally, the second information comprises at least one of the following:

[0212] (1) information for indicating a SUPI index value;

[0213] In the embodiments of the present application, the second information specifically adopts the form of SUPI index, which can save signaling overhead compared with the form of existing primary SUPI and secondary SUPI, and can ensure clear indication, and specific comparison is as follows:

[0214] Comparison from the aspect of signaling overhead:

[0215] The primary SUPI and the secondary SUPI need the terminal to indicate in advance to the network side which SUPI corresponds to the specific primary SUPI and the secondary SUPI, for example, indicating in advance that the primary SUPI corresponds to the first SUPI and the secondary SUPI corresponds to the second SUPI;

[0216] The SUPI index is determined by the first network side node itself, without the need for the terminal to indicate in advance, thereby saving signaling overhead.

[0217] In terms of indication clarity:

[0218] For the primary SUPI and the secondary SUPI, assuming that the primary SUPI corresponds to the first SUPI and the secondary SUPI corresponds to the second SUPI, if the access mode of the terminal changes, for example, the first SUPI changes to the third SUPI, at this time, the network side can only know that the second SUPI can correspond to the secondary SUPI, and whether the newly registered third SUPI corresponds to the primary SUPI or needs to be redefined, that is, the primary SUPI corresponds to the second SUPI and the secondary SUPI corresponds to the third SUPI, resulting in that the network side is not clear about the correspondence between the primary SUPI and the secondary SUPI and the specific SUPI.

[0219] However, in the form of the SUPI index, no matter how the SUPI registered by the terminal changes, the first network side node can correspondingly determine an SUPI index, ensuring clear indication.

[0220] (2) Information for indicating the primary SUPI and the secondary SUPI.

[0221] In the embodiments of the present application, the form of the primary SUPI and the secondary SUPI can be used to be compatible with the existing SUPI definition, and the implementation combined with the implementation of associating the first SUPI and the second SUPI according to the first PEI and the second PEI as described above can also achieve overall signaling overhead saving.

[0222] In another implementation, the information for indicating the primary SUPI and the secondary SUPI can also be used in combination with the information for indicating the SUPI index value. For example, the information for indicating the SUPI index value can indicate that the first SUPI corresponds to the primary SUPI and the second SUPI corresponds to the secondary SUPI. It can be understood that this combination of use can also save the signaling overhead of the terminal because it does not need to report any of the primary SUPI and the secondary SUPI to the network.

[0223] In an optional implementation, the second information corresponding to the target SUPI is determined as the first value.

[0224] The second information corresponding to the target SUPI is determined as the first value.

[0225] The target SUPI satisfies at least one of the following conditions:

[0226] (1) The target SUPI is any one of the first SUPI and the second SUPI.

[0227] Optionally, the target SUPI is the second registered SUPI among the first SUPI and the second SUPI. It should be noted that the second registration mentioned herein can refer to the second sending of the registration request. For example, among the first SUPI and the second SUPI, the terminal first sends the registration request of the first SUPI and then sends the registration request of the second SUPI, and at this time, the target SUPI is the second SUPI. Alternatively, the second registration can also refer to the second completion of the registration. For example, among the first SUPI and the second SUPI, the first SUPI completes the registration first and the second SUPI completes the registration later, and at this time, the target SUPI is the second SUPI.

[0228] (2) The target SUPI is the SUPI corresponding to the connection for updating the context.

[0229] It can be understood that the UDM updates the context after determining that the first SUPI and the second SUPI have the association. The UDM can update the context using the first UDR corresponding to the first SUPI, or can select the second UDR corresponding to the second SUPI to update the context. For example, under the condition that the UDM updates the context through the first UDR corresponding to the first SUPI, the UDM can determine that the first SUPI is the target SUPI. For another example, under the condition that the UDM updates the context through the second UDR corresponding to the second SUPI, the UDM can determine that the second SUPI is the target SUPI. In this way, the UDM determines the target SUPI without the terminal indicating the primary SUPI and the secondary SUPI to the network side, thereby achieving the beneficial effect of saving the signaling overhead of the terminal.

[0230] (3) the target SUPI is the SUPI corresponding to the connection used for sending the second information;

[0231] It can be understood that the UDM performs sending the second information after determining that the first SUPI and the second SUPI have a correlation. The UDM can send the second information using the first UDR corresponding to the first SUPI, or can select the second UDR corresponding to the second SUPI to send the second information. For example, in the case where the UDM sends the second information through the first UDR corresponding to the first SUPI, the UDM can determine that the first SUPI is the target SUPI. For another example, in the case where the UDM sends the second information through the second UDR corresponding to the second SUPI, the UDM can determine that the second SUPI is the target SUPI. In this way, the UDM determines the target SUPI, and the terminal does not need to indicate the primary SUPI and the secondary SUPI to the network side, thereby achieving the beneficial effect of saving signaling overhead of the terminal.

[0232] In the embodiments of the present application, the specific value of the second information is determined according to the rules (1)-(3) above, wherein in the case where the first SUPI is the target SUPI, the second information corresponding to the second SUPI is the second value; and in the case where the second SUPI is the target SUPI, the second information corresponding to the first SUPI is the second value.

[0233] The first value and the second value are different, for example, if the value of the second information is a 2-bit value, the first value can be '10', and the second value can be '01'. For example, if the value of the second information is a 1-bit value, the first value can be '1', and the second value can be '0'.

[0234] In an optional implementation, in the case where the target SUPI is the SUPI corresponding to the connection used for sending the second information, the second information is sent, including at least one of the following:

[0235] (1) in the case where the first network side node selects the connection corresponding to the first SUPI to send the second information, the first network side node sends the second information to the terminal through the third network side node corresponding to the first SUPI;

[0236] (2) in the case where the first network side node selects the connection corresponding to the second SUPI to send the second information, the first network side node sends the second information to the terminal through the third network side node corresponding to the second SUPI.

[0237] In the embodiments of the present application, the first network side node sends the second information to the terminal through the third network side node corresponding to the target SUPI, so that the terminal side can determine the data transmission strategy in combination with the value of the second information and the SUPI corresponding to the connection receiving the second information when receiving the second information.

[0238] The third network side node can be a UDR device or a PCF device, and in this application file, the case where the third network side node is a UDR device or a PCF device is exemplified.

[0239] In an optional implementation, the third information is updated, including at least one of the following:

[0240] (1) In the case where the third information contains AM context information, a first request message for requesting to update the AM context information is sent to the second network side node;

[0241] (2) In the case where the third information contains terminal subscription information, a second request message for requesting to update the terminal subscription information is sent to the third network side node;

[0242] (3) In the case where the third information contains data set information, a third request message for requesting to update the data set information is sent to the third network side node.

[0243] In an optional implementation, the second information is sent, including at least one of the following:

[0244] (1) The first network side node sends a registration accept message to the terminal through the second network side node, and the registration accept message includes the second information;

[0245] (2) The first network side node sends a configuration update message to the terminal through the second network side node, and the configuration update message includes the second information.

[0246] In the embodiments of the present application, the first network side node sends the second information to the terminal through the registration accept message or the configuration update message sent by the second network side node;

[0247] The second network side node can be an AMF device, and in this application file, the case where the second network side node is an AMF device is exemplified.

[0248] Specifically, in the embodiments of the present application, between the first SUPI and the second SUPI, it is assumed that the first SUPI is the first registered SUPI and the second SUPI is the second registered SUPI. It should be noted that the first / second registration described herein can refer to the order of sending the registration request, or can also refer to the order of completing the registration.

[0249] The first network side node sends a registration acceptance message to the terminal through the second network side node. Specifically, the first network side node can send the registration acceptance message to the terminal through the second network side node corresponding to the second SUPI. This is because when the first SUPI is registered first, the network side can not know that the terminal registers the first SUPI this time to perform Dualsteer, but when the second SUPI is registered later, it can be determined that the terminal needs to perform Dualsteer, and the first network side node determines the second information and carries the second information in the registration acceptance message corresponding to the first SUPI.

[0250] Similarly, the first network side node sends a configuration update message to the terminal through the second network side node. Specifically, the first network side node can send the configuration update message to the terminal through the second network side node corresponding to the first SUPI. This is because when the first SUPI is registered first, the network side can not know that the terminal registers the first SUPI this time to perform Dualsteer, but when the second SUPI is registered later, it can be determined that the terminal needs to perform Dualsteer, and the first network side node determines the second information and carries the second information in the configuration update message corresponding to the first SUPI.

[0251] Referring to FIG. 3, an information processing method is provided in the embodiment of the present application, and the execution subject of the method is a terminal. The terminal can be a terminal capable of performing Dualsteer, which can be referred to as a Dualsteer device. The method comprises the following steps:

[0252] Step 301: The terminal performs a third operation.

[0253] The third operation comprises at least one of the following:

[0254] (1) In the case where the terminal supports Dualsteer, the terminal sends a first PEI and a second PEI.

[0255] In the embodiment of the present application, the precondition for the terminal to send the first PEI and the second PEI is that the terminal supports Dualsteer.

[0256] (2) The terminal receives second information.

[0257] In the embodiment of the present application, the terminal receives the second information to determine the specific strategy of data transmission.

[0258] (3) The terminal performs data transmission according to the second information.

[0259] In the embodiment of the present application, the terminal determines the specific strategy of data transmission according to the second information.

[0260] The second information is used for at least one of the following: performing data transmission; selecting a path for data transmission; selecting a connection for data transmission; selecting a SUPI for data transmission; selecting a modem for data transmission; authorization of a data transmission mode (allowing or not allowing the first SUPI and the second SUPI to transmit simultaneously); and confirming that the Dualsteer function is available or unavailable.

[0261] In an optional implementation,

[0262] The terminal sends the first PEI, including:

[0263] The terminal sends the first PEI through a connection corresponding to the first SUPI.

[0264] The terminal sends the second PEI, including:

[0265] The terminal sends the second PEI through a connection corresponding to the second SUPI.

[0266] In the embodiments of the present application, the first PEI and the second PEI are specifically sent by the terminal to the first network side node through the connections corresponding to the first SUPI and the second SUPI, respectively. For example, the first PEI is carried in a registration request message in the process of registering the first SUPI by the terminal, and is sent to the first network side node through the connection corresponding to the first SUPI (which may include the first AMF corresponding to the first SUPI). The second PEI is carried in a registration request message in the process of registering the second SUPI by the terminal, and is sent to the first network side node through the connection corresponding to the second SUPI (which may include the second AMF corresponding to the second SUPI). It can be understood that the above-mentioned manner does not exclude the case that the registration message of the terminal further includes the second PEI when the first PEI is carried in a registration request message in the process of registering the first SUPI by the terminal, and is sent to the first network side node through the connection corresponding to the first SUPI (which may include the first AMF corresponding to the first SUPI). Similarly, the above-mentioned manner does not exclude the case that the registration message of the terminal further includes the first PEI when the second PEI is carried in a registration request message in the process of registering the second SUPI by the terminal, and is sent to the first network side node through the connection corresponding to the second SUPI (which may include the second AMF corresponding to the second SUPI).

[0267] In an optional implementation, the terminal receives the second information, including any one of the following:

[0268] (1) The terminal receives the first policy from a third network side node corresponding to the first SUPI;

[0269] (2) The terminal receives the second policy from a third network side node corresponding to the second SUPI;

[0270] At least one of the first policy and the second policy contains the content of the second information.

[0271] In the embodiments of the present application, the terminal specifically receives the second information in the following manner: receiving a first policy from a third network side node corresponding to the first SUPI or the second SUPI, and the first policy carries the second information, that is, the second information is provided to the terminal through a policy update process. The first policy can be referred to as an access selection policy (ASP), and can be specifically provided by a PCF corresponding to the first SUPI or the second SUPI.

[0272] In an optional implementation, the terminal receives the second information, including at least one of the following:

[0273] (1) The terminal receives a registration acceptance message from the second network side node, and the registration acceptance message contains the second information;

[0274] (2) The terminal receives a configuration update message from the second network side node, and the configuration update message contains the second information.

[0275] In the embodiments of the present application, the first network side node sends the second information to the terminal through the registration acceptance message or the configuration update message sent by the second network side node;

[0276] The second network side node can be an AMF device, and examples are given in the present application file assuming that the second network side node is an AMF device.

[0277] Specifically, in the embodiments of the present application, between the first SUPI and the second SUPI, it is assumed that the first SUPI is the first registered SUPI and the second SUPI is the second registered SUPI. It should be noted that the first / second registration described herein can refer to the order of sending a registration request, or can also refer to the order of completing registration.

[0278] The first network side node sends the registration acceptance message to the terminal through the second network side node, and specifically can be that the first network side node sends the registration acceptance message to the terminal through the second network side node corresponding to the second SUPI.

[0279] The first network side node sends the configuration update message to the terminal through the second network side node, and specifically can be that the first network side node sends the configuration update message to the terminal through the second network side node corresponding to the first SUPI.

[0280] In an optional implementation, the second information is information for distinguishing the first SUPI and the second SUPI;

[0281] Optionally, the second information includes at least one of the following:

[0282] (1) information for indicating a SUPI index value;

[0283] (2) information for indicating a primary SUPI and a secondary SUPI.

[0284] In an optional embodiment, the terminal determines to perform data transmission according to the second information, including at least one of the following:

[0285] The terminal determines a SUPI for performing data transmission according to the second information;

[0286] The terminal performs data transmission according to the SUPI for performing data transmission;

[0287] In the embodiments of the present application, after the terminal receives the second information, the terminal determines the SUPI for performing data transmission according to the second information, thereby further determining the path of data transmission, the connection of data transmission, and the modem of data transmission.

[0288] Compared with the prior art:

[0289] In the prior art, the UE sends a primary SUPI and a secondary SUPI indication to the network side, and the network side determines the primary and secondary information in the ASP based on the indication information of the UE, and then sends the ASP (with primary SUPI and secondary SUPI information) to the UE;

[0290] And the technical solution of the present application:

[0291] The network side (for example, UDM) determines the second information, and the UDM triggers the UDR / PCF to send the ASP (including the second information) to the UE, and at the same time, the UE also needs to determine the SUPI index locally, because the UE needs to confirm which SUPI corresponds to which SUPI index, and then knows how to use the ASP.

[0292] Wherein the determination manner of the terminal for the SUPI corresponding to the first value or the second value of the second information should be the same as the determination manner of the network side for the second information, that is, the terminal side and the network side should keep the same understanding for the second information.

[0293] Wherein the second information corresponding to the target SUPI is a first value;

[0294] Wherein the target SUPI satisfies at least one of the following:

[0295] (1) the target SUPI is any one of the first SUPI and the second SUPI;

[0296] Optionally, the target SUPI is the secondly registered SUPI among the first SUPI and the second SUPI. It should be noted that the secondly registered herein can refer to the secondly sent registration request. For example, among the first SUPI and the second SUPI, the terminal sends the registration request of the first SUPI first and then sends the registration request of the second SUPI, and at this time, the target SUPI is the second SUPI. Or the secondly registered can also refer to the secondly completed registration. For example, among the first SUPI and the second SUPI, the first SUPI completes the registration first and the second SUPI completes the registration later, and at this time, the target SUPI is the second SUPI.

[0297] (2) The target SUPI is the SUPI corresponding to the connection for updating the context;

[0298] It can be understood that the UDM updates the context after determining that the first SUPI and the second SUPI have the association. The UDM can update the context using the first UDR corresponding to the first SUPI, or can update the context using the second UDR corresponding to the second SUPI. For example, under the condition that the UDM updates the context through the first UDR corresponding to the first SUPI, the UDM can determine that the first SUPI is the target SUPI. For another example, under the condition that the UDM updates the context through the second UDR corresponding to the second SUPI, the UDM can determine that the second SUPI is the target SUPI. In this way, the UDM determines the target SUPI, and the terminal does not need to indicate the primary SUPI and the secondary SUPI to the network side, thereby achieving the beneficial effect of saving the signaling overhead of the terminal.

[0299] (3) The target SUPI is the SUPI corresponding to the connection for sending the second information;

[0300] It can be understood that the UDM sends the second information after determining that the first SUPI and the second SUPI have the association. The UDM can send the second information using the first UDR corresponding to the first SUPI, or can send the second information using the second UDR corresponding to the second SUPI. For example, under the condition that the UDM sends the second information through the first UDR corresponding to the first SUPI, the UDM can determine that the first SUPI is the target SUPI. For another example, under the condition that the UDM sends the second information through the second UDR corresponding to the second SUPI, the UDM can determine that the second SUPI is the target SUPI. At this time, the UE determines the target SUPI based on the connection of the second information, and in this way, the terminal does not need to indicate the primary SUPI and the secondary SUPI to the network side, thereby achieving the beneficial effect of saving the signaling overhead of the terminal.

[0301] Wherein, in the case that the first SUPI is the target SUPI, the second information corresponding to the second SUPI is the second value; in the case that the second SUPI is the target SUPI, the second information corresponding to the first SUPI is the second value.

[0302] Wherein, the first value is different from the second value.

[0303] In the embodiments of the present application, in order to ensure that the terminal side and the network side understand the value of the second information in the same way, the terminal adopts the same rule as the network side to understand the second information. In this way, in the step of performing data transmission by the terminal according to the second information, the terminal can specifically select at least one of the following to perform data transmission according to the value of the second information: the path of data transmission; the connection of data transmission; the SUPI of data transmission; and the modem of data transmission.

[0370] The technical solutions of the present application will be described below in combination with specific application examples:

[0371] Example one:

[0372] The main idea of this embodiment is that the UDM determines that SUPI-1 and SUPI-2 come from the same UE or determines that SUPI-1 and SUPI-2 have an association based on the association relationship between PEI-2 and PEI-1, thereby triggering the update of the UE context and further triggering the sending or updating of the ASP. The main problem solved is how the UDM determines that SUPI-1 and SUPI-2 have an association (or how the UDM determines that SUPI-1 and SUPI-2 come from the same UE), so that the Dualsteer device can be correctly associated in the network.

[0373] The corresponding signaling flow is shown in FIG. 6a:

[0374] Step 1: SUPI-1 of the Dualsteer device is registered in the network. Wherein, in the case that the Dualsteer device supports Dualsteer, the SUPI-1 of the Dualsteer device carries PEI-1 in the network registration request message.

[0375] Optionally, in the case that the AMF-1 receives the PEI-1 and the Dualsteer device indicates that it supports Dualsteer, the AMF-1 sends the PEI-1 to the UDM.

[0376] Step 2: SUPI-2 of the Dualsteer device is registered in the network. Wherein, in the case that the Dualsteer device supports Dualsteer, the SUPI-2 of the Dualsteer device carries PEI-2 in the network registration request message.

[0377] Optionally, in the case that the AMF-2 receives the PEI-2 and the Dualsteer device indicates that it supports Dualsteer, the AMF-2 sends the PEI-2 to the UDM.

[0378] That is, the first information is obtained by the first network side node through the above steps 1 and 2, wherein the first network side node is specifically the UDM in the embodiment, and the first information includes PEI-1 and PEI-2.

[0379] Step 3: The UDM determines at least one of the following based on the association information of PEI-1 and PEI-2: SUPI-1 and SUPI-2 come from the same UE or device; SUPI-1 and SUPI-2 have an association.

[0380] Optionally, the association information of PEI-1 and PEI-2 indicates that PEI-1 and PEI-2 come from the same UE or device.

[0381] In some embodiments, PEI-1 and PEI-2 can come from different UEs or devices, and the association information of PEI-1 and PEI-2 indicates that PEI-1 and PEI-2 have an association.

[0382] Optionally, the SUPI-1 and the SUPI-2 have an association, including: SUPI-1 and SUPI-2 are used to perform Dualsteer performed by the Dualsteer device.

[0383] Step 4: After determining at least one of SUPI-1 and SUPI-2 come from the same UE or device, SUPI-1 and SUPI-2 have an association, the UDM updates the UE context at the UDR. It is worth mentioning that the UDM can choose to update the UE context at the UDR of access-1 or access-2.

[0384] Step 5: If the UDM chooses access-1 corresponding to SUPI-1, UDR-1 triggers PCF-1 to update the ASP of SUPI-1 of the Dualsteer device. In some embodiments, the PCF sends the ASP to the UE through the UCU procedure or the DL NAS TRANSPORT procedure.

[0385] If the UDM chooses access-2 corresponding to SUPI-2, UDR-2 triggers PCF-2 to update the ASP of SUPI-2 of the Dualsteer device. In some embodiments, the PCF sends the ASP to the UE through the UCU procedure or the DL NAS TRANSPORT procedure.

[0386] In some embodiments, the UDM always updates the UE context through the UDR corresponding to the SUPI registered with the UDM the second time.

[0387] In some embodiments, the UDM updates the UE context through both access-1 corresponding to SUPI-1 and access-2 corresponding to SUPI-2.

[0388] Step 6: If UDR-1 triggers PCF-1 to update or send the ASP of SUPI-1 of the Dualsteer device, the PCF updates or sends the ASP to SUPI-1.

[0389] If UDR-2 triggers PCF-2 to update or send the ASP of SUPI-2 of the Dualsteer device, the PCF updates or sends the ASP to SUPI-2.

[0390] Embodiment Two:

[0391] The main idea of this embodiment is to distinguish the roles of the two SUPIs through the UDM, and then distinguish the corresponding terminal policies of the two SUPIs, thereby solving the problem of the Dualsteer device needing to indicate identity information to the network, saving UE signaling, and solving the risk of the SUPI of the Dualsteer device being exposed on the air interface.

[0392] The corresponding signaling flowchart is shown in FIG. 6b:

[0393] Step 1: The UDM determines at least one of the following: SUPI-1 and SUPI-2 come from the same UE or device; SUPI-1 and SUPI-2 have an association.

[0394] It can be understood that the specific implementation of step 1 can adopt the prior art, that is, adopt the existing way of associating SUPI-1 and SUPI-2, or also can adopt the association way in the implementation one, that is, realize the association of SUPI-1 and SUPI-2 through the association information of PEI-1 and PEI-2.

[0395] Optionally, the association information of the PEI-1 and the PEI-2 indicates that the PEI-1 and the PEI-2 come from the same UE or device.

[0396] Optionally, the SUPI-1 and the SUPI-2 have an association includes: the SUPI-1 and the SUPI-2 are used for a Dualsteer device to perform Dualsteer.

[0397] Step 2: The UDM determines a SUPI index, wherein the SUPI index is used for a Dualsteer terminal to select at least one of the following when transmitting data: a path of data transmission; an access mode of data transmission; a connection for data transmission; a SUPI for data transmission; and a modem for data transmission.

[0398] Optionally, the connection for data transmission includes at least one of the following: a PDU session; a PDN connection; an EPS bearer; and a QoS flow.

[0399] Optionally, the access mode includes at least one of the following: 3GPP access; and Non-3GPP access.

[0400] Optionally, the SUPI for data transmission is used for a Dualsteer device to perform a Dualsteer feature.

[0401] Optionally, the UDM sets a SUPI index corresponding to a SUPI used for updating a UE context to a first value, and sets a SUPI index corresponding to another SUPI to a second value, wherein the first value and the second value are different.

[0402] In some embodiments, the UDM sets a SUPI index corresponding to a SUPI used for updating a UE context to a first value

[0403] Optionally, the UDM determines the SUPI index based on the SUPI of the sending ASP. Optionally, the UDM determines the SUPI index based on the SUPI of the sending ASP, including: the UDM determines the SUPI of the second registration as the SUPI of the sending ASP, and determines the SUPI index based on the SUPI.

[0404] In some embodiments, the SUPI index is 2-bit indication information, wherein the UDM sets the SUPI index corresponding to the SUPI used to update the UE context as '01', and sets the SUPI index corresponding to another SUPI as '10'.

[0405] That is, an embodiment of the SUPI index is:

[0406] Bits

[0407] 2 1

[0408] 0 0 reserved, that is, the first bit is 0, the second bit is 0, and the corresponding SUPI index is set to '00';

[0409] 0 1 Primary SUPI, that is, the first bit is 0, the second bit is 1, and the corresponding SUPI index is set to '01';

[0410] 1 0 Secondary SUPI, that is, the first bit is 1, the second bit is 0, and the corresponding SUPI index is set to '10';

[0411] 1 1 reserved, that is, the first bit is 1, the second bit is 1, and the corresponding SUPI index is set to '11';

[0412] It is worth mentioning that in the above embodiment, assuming that the UDM sets the SUPI index corresponding to SUPI-2 as '01', in the ASP received by the Dualsteer device, the SUPI index of the traffic that needs to be transmitted through SUPI-2 will all be marked as '01'. Correspondingly, the SUPI index of the traffic that needs to be transmitted through SUPI-1 will all be marked as '10'. In this way, even if the Dualsteer device does not indicate the Primary SUPI or the Secondary SUPI to the network side, the Dualsteer device can correctly determine through the SUPI index in the ASP which traffic should be transmitted through which SUPI. At the same time, the risk of the Dualsteer device transmitting the SUPI in the air interface can also be avoided.

[0413] In some embodiments, the SUPI index is 1 bit indication information, wherein the UDM sets the SUPI index corresponding to the SUPI used to update the UE context as '1', and sets the SUPI index corresponding to another SUPI as '1'. That is, one implementation of the SUPI index is:

[0414] Bits

[0415] 1

[0416] 1 Primary SUPI, i.e., the SUPI index is set to '1';

[0417] 0 Secondary SUPI, i.e., the SUPI index is set to '0';

[0418] It is worth mentioning that in the above embodiment, assuming that the UDM sets the SUPI index corresponding to SUPI-2 as '1', in the ASP received by the Dualsteer device, the SUPI index of the traffic that needs to be transmitted through SUPI-2 will all be marked as '1'. Correspondingly, the SUPI index of the traffic that needs to be transmitted through SUPI-1 will all be marked as '0'. In this way, even if the Dualsteer device does not indicate the Primary SUPI or the Secondary SUPI to the network side, the Dualsteer device can correctly determine through the SUPI index in the ASP which traffic should be transmitted through which SUPI. At the same time, the risk of the Dualsteer device transmitting the SUPI in the air interface can also be avoided.

[0419] Optionally, the UDM sends the SUPI index to the Dualsteer device.

[0420] In some embodiments, the SUPI index is carried in the registration acceptance message sent by AMF-2 to SUPI-2.

[0421] In some embodiments, the SUPI index is carried in the UE configuration update message sent by AMF-1 to SUPI-1.

[0422] Step 3: After determining that at least one of SUPI-1 and SUPI-2 come from the same UE or device, and SUPI-1 and SUPI-2 have an association, the UDM updates the UE context at the UDR. It is worth mentioning that the UDM can choose the UDR of access-1 or access-2 to update the UE context.

[0423] Step 4: If UDM selects access-1 corresponding to SUPI-1, UDR-1 triggers PCF-1 to update ASP to SUPI-1 of the Dualsteer device, wherein the ASP includes SUPI index. In some embodiments, the PCF sends the ASP to the UE through the UCU procedure or the DL NAS TRANSPORT procedure.

[0424] If UDM selects access-2 corresponding to SUPI-2, UDR-2 triggers PCF-2 to update ASP to SUPI-2 of the Dualsteer device, wherein the ASP includes SUPI index. In some embodiments, the PCF sends the ASP to the UE through the UCU procedure or the DL NAS TRANSPORT procedure.

[0425] Step 5: If UDR-1 triggers PCF-1 to update or send ASP to SUPI-1 of the Dualsteer device, PCF-1 updates or sends the ASP to SUPI-1.

[0426] If UDR-2 triggers PCF-2 to update or send ASP to SUPI-2 of the Dualsteer device, PCF-2 updates or sends the ASP to SUPI-2.

[0427] Optionally, after receiving the ASP from the PCF, the Dualsteer device selects at least one of the following based on the SUPI index when performing data transmission: path of data transmission; access mode of data transmission; connection of data transmission; SUPI of data transmission; modem of data transmission.

[0428] The Dualsteer device performs data transmission based on the SUPI index, including: the Dualsteer device determines the corresponding at least one of the following according to the value of the SUPI index: path of data transmission; access mode of data transmission; connection of data transmission; SUPI of data transmission; modem of data transmission.

[0429] The Dualsteer device determines the corresponding SUPI index as a first value or a second value according to the path of receiving the ASP, thereby ensuring that the SUPI index is understood in the same way as the network side, for example, if the path of receiving the ASP is the path corresponding to SUPI-1 (access-1), the value of the SUPI index corresponding to SUPI-1 is determined as 1.

[0430] Embodiment Three:

[0431] The main idea of the embodiment is that after the UDM determines that SUPI-1 and SUPI-2 come from the same UE or determines that SUPI-2 has an association with SUPI-1, the UDM synchronizes the UE context of AMF-1 and SMF-1. The main problem solved is how the network synchronizes the Dualsteer terminal UE context, so that the Dualsteer device can be correctly associated in the network

[0432] The corresponding signaling flow is shown in FIG. 6c.

[0433] Step 1: SUPI-1 of the Dualsteer device has been registered in the network.

[0434] Step 2: SUPI-2 of the Dualsteer device requests registration from the network.

[0435] Step 3: The UDM determines at least one of the following: SUPI-1 and SUPI-2 come from the same UE or device; SUPI-1 and SUPI-2 have an association.

[0436] It can be understood that the specific implementation of step 3 can adopt the prior art, that is, adopt the existing method of associating SUPI-1 and SUPI-2, or also can adopt the association method in implementation one, that is, realize the association of SUPI-1 and SUPI-2 through the association information of PEI-1 and PEI-2.

[0437] Optionally, the association information of the PEI-1 and the PEI-2 indicates that the PEI-1 and the PEI-2 come from the same UE or device.

[0438] Optionally, the SUPI-1 and the SUPI-2 have an association, including: the SUPI-1 and the SUPI-2 are used for the Dualsteer device to perform a Dualsteer characteristic.

[0439] Steps 4 and 5: The UDM updates the UE context information of at least one of AMF-1 and SMF-1.

[0440] In some embodiments, when the UDM updates the UE context information of AMF-1, the UE context information refers to AM context.

[0441] In some embodiments, when the UDM updates the UE context information of SMF-1, the UE context information refers to SM context.

[0442] Optionally, after accepting the registration request of SUPI-2, the UDM updates the UE context information of at least one of AMF-1 and SMF-1.

[0443] Optionally, after determining at least one of that SUPI-1 and SUPI-2 come from the same UE or device, and that SUPI-1 and SUPI-2 have an association, the UDM updates UE context information of at least one of the AMF-1 and the SMF-1.

[0444] It is worth mentioning that in some embodiments, the SMF-1 and the SMF-2 can be the same SMF, in which case the UDM does not need to update the context information of the SMF-2.
