[0090] Before the technical solutions of the embodiments of the present disclosure are introduced, related technologies are introduced.

[0091] Currently, a DualSteer terminal is composed of two separate user equipment (UE), each of which has a SUPI. Two UEs can establish two independent and associated access PDU sessions, which support the steer and switch functions. Analogous to the access traffic steering, switching, and splitting (ATSSS) related functions, the steer function in DualSteer needs to support switching the session access of UE1 to the session access of UE2, and the switch function needs to support switching all traffic of the session of UE1 to the session of UE2, and vice versa. Therefore, the PDU sessions established by the two UEs need to be associated, and the same SMF needs to be selected for session management and the same user plane function (UPF) as the session anchor point.

[0092] Currently, there are some details that need to be supplemented in the study of DualSteer. Since the two UEs are independent UEs, and each UE can independently build a PDU session, but the PDU session types of the two UEs are not discussed, and the session type is not specified in the routing selection policy (URSP) of the two UEs, there may be a case where the UE requests to establish a PDU session, and the data network name (DNN) and single network slice selection assistance information (S-NSSAI) requested by the UE support multiple session types, such as IPv4, IPv6, IPv4 / v6 in IP type sessions, Ethernet type sessions, and unstructured sessions. Therefore, there may be a case where the PDU session types requested by the two UEs are inconsistent. When the PDU session types requested by the UEs are inconsistent, the types of traffic messages on the PDU session may be different, thereby causing the inability to support the steer and switch functions in DualSteer.

[0093] Therefore, the technical problem to be solved by the present disclosure is how to ensure that the types of PDU sessions established by two UEs in a dual steer terminal meet preset conditions, such as consistency, so as to ensure the normal operation of steer and switch functions in the dual steer.

[0094] Based on this, in the embodiments of the present disclosure, the SMF processes the request for establishing a PDU session initiated by the second terminal according to the type of the PDU session established by the first terminal and the type of the PDU session requested by the second terminal.

[0095] Referring to FIG. 1, FIG. 1 is a schematic diagram of the implementation flow of the information processing method of the present disclosure, which is applied to an SMF, as shown in FIG. 1, the method comprises the following steps:

[0096] Step 101: processing the request for establishing a PDU session initiated by the second terminal according to the type of the PDU session established by the first terminal and the type of the PDU session requested by the second terminal.

[0097] It can be understood that the first terminal and the second terminal can form a dual stream (DS, DualSteer) terminal.

[0098] Among them, the dual stream (DS, DualSteer) terminal can be composed of two separate user equipment (UE, User Equipment), each UE has a SUPI, and two UEs can establish two independent and associated access PDU sessions.

[0099] In some embodiments, the type of the PDU session established by the first terminal includes one of the following:

[0105] Ethernet type session;

[0106] Unstructured session.

[0107] Among them, the IP type session includes IPv4, IPv6, IPv4 / v6, etc.

[0108] In some embodiments, the method further comprises:

[0109] Obtaining a type of the PDU session established by the first terminal and obtaining a type of the PDU session requested by the second terminal.

[0110] In some embodiments, the obtaining the type of the PDU session established by the first terminal comprises:

[0111] Receiving a PDU session creation SM context request sent by the AMF; the PDU session creation SM context request carries a first identifier; the first identifier is used to associate a SUPI of the first terminal with a SUPI of the second terminal.

[0112] Obtaining a type of the PDU session related to the SUPI of the first terminal.

[0113] Here, the first identifier can be a dual stream (DS) identifier.

[0114] In some embodiments, the obtaining the type of the PDU session requested by the second terminal comprises:

[0115] According to the request of the second terminal for establishing the PDU session, obtaining the type of the PDU session requested by the second terminal.

[0116] The following describes the process of how the SMF processes the request of the second terminal for establishing the PDU session.

[0117] In a first case, the SMF determines whether the type of the PDU session requested by the second terminal is consistent with the type of the PDU session established by the first terminal, and obtains a determination result; according to the determination result, it is determined whether to allow the request of the second terminal for establishing the PDU session.

[0118] Based on this, in some embodiments, the processing the request of the second terminal for establishing the PDU session according to the type of the PDU session established by the first terminal and the type of the PDU session requested by the second terminal comprises:

[0119] If the type of the PDU session established by the first terminal and the type of the PDU session requested by the second terminal are the same, the SMF allows the request of the second terminal for establishing the PDU session.

[0120] Referring to FIG. 2, FIG. 2 is an implementation flowchart of the processing of the request of the second terminal for establishing the PDU session according to the embodiments of the present disclosure, as shown in FIG. 2, comprising steps 201 to 207:

[0121] Step 201: A first terminal (UE1) has applied its own SUPI (SUPI1) to establish a PDU session, and sends a first identity, i.e., a dual steering (DS) identity, to an AMF when registering or establishing the PDU session.

[0122] Here, the first identity is used to associate the SUPI (SUPI1) of the first terminal (UE1) with the SUPI (SUPI2) of a second terminal (UE2).

[0123] Step 202: The second terminal (UE2) sends a request for establishing a PDU session to the AMF; the request for establishing the PDU session carries the SUPI (SUPI2) of the second terminal (UE2) and the first identity (DS identity).

[0124] Step 203: The AMF selects, according to the first identity (DS identity) sent by the first terminal (UE1) and the request for establishing a PDU session sent by the second terminal (UE2), the same SMF for the SUPI (SUPI2) of the second terminal (UE2) as for the SUPI (SUPI1) of the first terminal (UE1).

[0125] Step 204: The AMF sends a PDU session create SM context request to the SMF; the PDU session create SM context request carries the first identity (i.e., the DS identity).

[0126] Here, the PDU session create SM context request can also carry the request for establishing a PDU session initiated by the second terminal (UE2).

[0127] Step 205: The SMF obtains the type of the PDU session established by the first terminal (UE1) and the type of the PDU session requested by the second terminal (UE2).

[0128] Here, the SMF obtains the type of the PDU session established by the first terminal (UE1) includes: after receiving the PDU session create SM context request sent by the AMF, the SMF identifies, according to the first identity (DS identity), that the SUPI (SUPI2) of the second terminal (UE2) is associated with the SUPI (SUPI1) of the first terminal (UE1), then obtains the session information related to the SUPI (SUPI1) of the first terminal (UE1) to obtain the type of the PDU session related to the SUPI (SUPI1) of the first terminal (UE1), wherein the session information includes the type of the PDU session established by the first terminal (UE1) and / or a PDU session anchor point, etc.

[0129] Here, the type of the PDU session requested by the second terminal (UE2) includes one of the following:

[0130] Here, the type of the PDU session established by the first terminal (UE1) includes one of the following:

[0131] An IP type session;

[0132] An Ethernet type session;

[0133] A non-structured session.

[0134] Here, the type of the PDU session requested by the second terminal (UE2) includes one of the following:

[0135] An IP type session;

[0136] An Ethernet type session;

[0137] A non-structured session.

[0138] The IP type session includes IPv4, IPv6, IPv4 / v6, etc.

[0139] Step 206: The SMF determines whether the type of the PDU session requested by the second terminal (UE2) and the type of the PDU session established by the first terminal (UE1) satisfy a first preset condition, and if the first preset condition is satisfied, the SMF allows the request of the second terminal (UE2) to establish a PDU session, and the session establishment process continues.

[0140] Here, the first preset condition includes:

[0141] The type of the PDU session requested by the second terminal (UE2) is the same as the type of the PDU session established by the first terminal (UE1).

[0142] Here, the type of the PDU session requested by the second terminal (UE2) is the same as the type of the PDU session established by the first terminal (UE1), including the following:

[0143] The type of the PDU session established by the first terminal (UE1) is an IPv4 / v6 in an IP type session, and the type of the PDU session requested by the second terminal (UE2) to establish is an IPv4 / v6 in an IP type session;

[0144] Or,

[0145] The type of the PDU session established by the first terminal (UE1) is IPv4 in an IP type session, and the type of the PDU session requested by the second terminal (UE2) to establish is IPv4 in an IP type session;

[0146] Alternatively,

[0147] The type of the PDU session established by the first terminal (UE1) is IPv6 in an IP type session, and the type of the PDU session requested by the second terminal (UE2) to establish is IPv6 in an IP type session;

[0148] Alternatively,

[0149] The type of the PDU session established by the first terminal (UE1) is an Ethernet type session, and the type of the PDU session requested by the second terminal (UE2) to establish is an Ethernet type session;

[0150] Alternatively,

[0151] The type of the PDU session established by the first terminal (UE1) is a non-structured session, and the type of the PDU session requested by the second terminal (UE2) to establish is a non-structured session.

[0152] Step 207: If the first preset condition is not met, the SMF rejects the request of the second terminal (UE2) to establish a PDU session.

[0153] Here, the first preset condition is not met, including:

[0154] The type of the PDU session requested by the second terminal (UE2) is inconsistent with the type of the PDU session established by the first terminal (UE1).

[0155] Here, the type of the PDU session requested by the second terminal (UE2) is inconsistent with the type of the PDU session established by the first terminal (UE1), including:

[0156] The type of the PDU session established by the first terminal (UE1) is an IP type session, and the type of the PDU session requested by the second terminal (UE2) to establish is an Ethernet type session or a non-structured session;

[0157] Alternatively,

[0158] The type of the PDU session established by the first terminal (UE1) is a non-structured session, and the type of the PDU session requested by the second terminal (UE2) to establish is an IP type session or an Ethernet type session;

[0159] Alternatively,

[0160] The type of the PDU session established by the first terminal (UE1) is an Ethernet type session, and the type of the PDU session requested by the second terminal UE2 is an IP type session or a non-structured session.

[0161] Here, the SMF rejects the request of the second terminal (UE2) for establishing a PDU session, including: the SMF replies to reject the establishment of the PDU session by the second terminal (UE2) by sending, to the AMF, rejection information for a PDU session creation SM context request; and the rejection information contains a reason for rejecting the establishment of the PDU session by the second terminal (UE2).

[0162] That is, if the type of the PDU session requested by the second terminal (UE2) is inconsistent with the type of the PDU session established by the first terminal (UE1), the SMF rejects the establishment of the PDU session by the second terminal (UE2) and sends rejection information indicating that the session establishment is rejected because the PDU session type is incorrect.

[0163] In the embodiments of the present disclosure, if the SMF determines that the type of the PDU session requested by the second terminal (UE2) is consistent with the type of the PDU session established by the first terminal (UE1), the request of the second terminal (UE2) for establishing a PDU session is allowed; if the types of the PDU sessions are inconsistent, the request of the second terminal (UE2) for establishing a PDU session is rejected.

[0164] In the second case, the SMF determines whether the type of the PDU session requested by the second terminal is inconsistent with but compatible with the type of the PDU session established by the first terminal, and obtains a determination result; and according to the determination result, it is determined whether to allow the request of the second terminal for establishing a PDU session.

[0165] Based on this, in some embodiments, the processing of the request of the second terminal for establishing a PDU session includes:

[0166] If the type of the PDU session established by the first terminal and the type of the PDU session requested by the second terminal are not the same but are compatible, the SMF allows the request of the second terminal for establishing a PDU session.

[0167] Referring to FIG. 3, FIG. 3 is a flowchart illustrating the implementation of the processing of the request of the second terminal for establishing a PDU session according to an embodiment of the present disclosure, as shown in FIG. 3, the processing includes steps 301 to 308:

[0168] Step 301: The first terminal (UE1) has applied its own SUPI (SUPI1) to establish a PDU session, and sends a first identity, i.e., a dual steering (DS) identity, to the AMF when registering or establishing the PDU session.

[0169] Here, the first identity is used to associate the SUPI (SUPI1) of the first terminal (UE1) with the SUPI (SUPI2) of the second terminal (UE2).

[0170] Step 302: The second terminal (UE2) sends a request for establishing a PDU session to the AMF; the request for establishing a PDU session carries the SUPI (SUPI2) of the second terminal (UE2) and the first identity (DS identity).

[0171] Step 303: The AMF selects the same SMF for the SUPI (SUPI2) of the second terminal (UE2) as the SUPI (SUPI1) of the first terminal (UE1) according to the first identity (DS identity) sent by the first terminal (UE1) and the request for establishing a PDU session sent by the second terminal (UE2).

[0172] Step 304: The AMF sends a PDU session creation SM context request to the SMF; the PDU session creation SM context request carries the first identity (i.e., the DS identity).

[0173] Here, the PDU session creation SM context request can also carry the request for establishing a PDU session initiated by the second terminal (UE2).

[0174] Step 305: The SMF obtains the type of the PDU session established by the first terminal (UE1) and the type of the PDU session requested by the second terminal (UE2).

[0175] Here, the SMF obtains the type of the PDU session established by the first terminal (UE1) includes: after receiving the PDU session creation SM context request sent by the AMF, the SMF identifies that the SUPI (SUPI2) of the second terminal (UE2) is associated with the SUPI (SUPI1) of the first terminal (UE1) according to the first identity (DS identity), then obtains the session information related to the SUPI (SUPI1) of the first terminal (UE1) to obtain the type of the PDU session related to the SUPI (SUPI1) of the first terminal (UE1), wherein the session information includes the type of the PDU session established by the first terminal (UE1) and / or the PDU session anchor point, etc.

[0176] Here, the type of the PDU session requested by the second terminal (UE2) includes one of the following:

[0183] Ethernet type session;

[0184] Unstructured session.

[0185] Wherein, the IP type session includes IPv4, IPv6, IPv4 / v6, etc.

[0186] Step 306: The SMF determines whether the type of the PDU session requested by the second terminal (UE2) and the type of the PDU session established by the first terminal (UE1) meet a first preset condition, and if the first preset condition is met, the SMF allows the PDU session establishment request of the second terminal (UE2), and the session establishment process continues.

[0187] Here, the first preset condition includes:

[0188] The type of the PDU session requested by the second terminal (UE2) is the same as the type of the PDU session established by the first terminal (UE1).

[0189] Step 307: If the first preset condition is not met, the SMF determines whether the type of the PDU session requested by the second terminal (UE2) and the type of the PDU session established by the first terminal (UE1) meet a second preset condition, and if the second preset condition is met, the SMF allows the PDU session establishment request of the second terminal (UE2), and the session establishment process continues.

[0190] Here, the second preset condition includes:

[0191] The type of the PDU session requested by the second terminal (UE2) is different from the type of the PDU session established by the first terminal (UE1), but is compatible.

[0192] Here, the type of the PDU session requested by the second terminal (UE2) is different from the type of the PDU session established by the first terminal (UE1), but is compatible, including the following:

[0195] The type of the PDU session established by the first terminal (UE1) is IPv4 or IPv6, and the type of the PDU session requested by the second terminal (UE2) to establish is IPv4 / v6.

[0196] That is, the type of the PDU session requested by the second terminal (UE2) and the type of the PDU session established by the first terminal (UE1) are both IP type sessions, and if the type of one PDU session is IPv4 / v6 and the type of the other PDU session is IPv4 or IPv6, it means that the types are different, but can be compatible.

[0197] Step 308: If the second preset condition is not met, the SMF rejects the request of the second terminal (UE2) to establish a PDU session.

[0198] Here, the second preset condition is not met, including:

[0199] The type of the PDU session requested by the second terminal (UE2) is inconsistent with the type of the PDU session established by the first terminal (UE1), and cannot be compatible.

[0200] Here, the type of the PDU session requested by the second terminal (UE2) is inconsistent with the type of the PDU session established by the first terminal (UE1), and cannot be compatible, including:

[0201] The type of the PDU session established by the first terminal (UE1) is an IP type session, and the type of the PDU session requested by the second terminal (UE2) is an Ethernet type session or a non-structured session;

[0202] Or,

[0205] The type of the PDU session established by the first terminal (UE1) is an Ethernet type session, and the type of the PDU session requested by the second terminal UE2 is an IP type session or a non-structured session.

[0206] Here, if the type of the PDU session requested by the second terminal (UE2) is inconsistent with the type of the PDU session established by the first terminal (UE1) and is not compatible, the SMF rejects the establishment of the PDU session by the second terminal (UE2) and sends a rejection message indicating that the session establishment is rejected because the PDU session type is incorrect.

[0207] Here, when the type of the PDU session requested by the second terminal (UE2) is inconsistent with the type of the PDU session established by the first terminal (UE1) and is not compatible, the SMF replies to reject the establishment of the PDU session by the second terminal (UE2) by sending a rejection message for the PDU session creation SM context request to the AMF; the rejection message contains the reason for rejecting the establishment of the PDU session by the second terminal (UE2).

[0208] In the embodiments of the present disclosure, if the SMF determines that the type of the PDU session requested by the second terminal (UE2) is different from the type of the PDU session established by the first terminal (UE1) but is compatible, the establishment of the PDU session by the second terminal (UE2) is allowed; if the types of the PDU sessions are different and are not compatible, the establishment of the PDU session by the second terminal (UE2) is rejected.

[0209] In the third case, the SMF determines whether the type of the PDU session requested by the second terminal is inconsistent with the type of the PDU session established by the first terminal and is not compatible but can be converted to an IP type, and obtains a determination result; according to the determination result, it is determined whether to allow the request of the second terminal to establish the PDU session.

[0210] Based on this, in some embodiments, the processing of the request of the second terminal to establish the PDU session includes:

[0211] If the type of the PDU session established by the first terminal and the type of the PDU session requested by the second terminal are different and are not compatible, but can be converted to an IP type, the SMF allows the request of the second terminal to establish the PDU session, and / or the SMF identifies the second terminal.

[0212] In some embodiments, the processing of the request for establishing a PDU session initiated by the second terminal comprises:

[0213] If the type of the PDU session established by the first terminal and the type of the PDU session requested by the second terminal are different and incompatible, and IP type conversion cannot be performed, the SMF rejects the request for establishing a PDU session by the second terminal.

[0214] In some embodiments, the method further comprises:

[0219] Step 401: The first terminal (UE1) has established a PDU session by applying its own SUPI (SUPI1), and when registering or establishing a PDU session, sends a first identifier, i.e., a dual flow (DS, DualSteer) identifier, to the AMF.

[0220] Here, the first identifier is used to associate the SUPI (SUPI1) of the first terminal (UE1) with the SUPI (SUPI2) of the second terminal (UE2).

[0221] Step 402: The second terminal (UE2) sends a request for establishing a PDU session to the AMF; the request for establishing a PDU session carries the SUPI (SUPI2) of the second terminal (UE2) and the first identifier (DS identifier).

[0222] Step 403: The AMF selects the same SMF for the SUPI (SUPI2) of the second terminal (UE2) as the PDU session of the SUPI (SUPI1) of the first terminal (UE1) according to the first identifier (DS identifier) sent by the first terminal (UE1) and the request for establishing a PDU session sent by the second terminal (UE2).

[0223] Step 404: The AMF sends a PDU session creation SM context request to the SMF; the PDU session creation SM context request carries the first identifier (i.e., the DS identifier).

[0224] Here, the PDU session creation SM context request can also carry the request of the second terminal (UE2) to initiate establishment of a PDU session.

[0225] Step 405: The SMF obtains the type of the PDU session established by the first terminal (UE1) and the type of the PDU session requested by the second terminal (UE2).

[0226] Here, the SMF obtaining the type of the PDU session established by the first terminal (UE1) includes: after the SMF receives the PDU session creation SM context request sent by the AMF, identifying, according to the first identifier (DS identifier), that the SUPI (SUPI2) of the second terminal (UE2) is associated with the SUPI (SUPI1) of the first terminal (UE1), then obtaining the session information related to the SUPI (SUPI1) of the first terminal (UE1) to obtain the type of the PDU session related to the SUPI (SUPI1) of the first terminal (UE1), wherein the session information includes the type of the PDU session established by the first terminal (UE1) and / or a PDU session anchor point, etc.

[0227] Here, the SMF obtaining the type of the PDU session requested by the second terminal (UE2) includes: after the SMF receives the PDU session creation SM context request sent by the AMF, obtaining the type of the PDU session requested by the second terminal (UE2) according to the request of the second terminal (UE2) to initiate establishment of a PDU session. That is, the request of the second terminal (UE2) to initiate establishment of a PDU session carries the type of the PDU session requested by the second terminal (UE2).

[0228] Here, the type of the PDU session established by the first terminal (UE1) includes one of the following:

[0229] IP type session;

[0230] Ethernet type session;

[0231] Non-structured session.

[0232] Here, the type of the PDU session requested by the second terminal (UE2) includes one of the following:

[0233] IP type session;

[0234] Ethernet type session;

[0235] Non-structured session.

[0236] The IP type session includes IPv4, IPv6, IPv4 / v6, etc.

[0237] Step 406: The SMF determines whether the type of the PDU session requested by the second terminal (UE2) and the type of the PDU session established by the first terminal (UE1) meet a first preset condition, and if the first preset condition is met, the SMF allows the request of the second terminal (UE2) to establish a PDU session, and the session establishment process continues.

[0238] Here, the first preset condition includes:

[0239] The type of the PDU session requested by the second terminal (UE2) is the same as the type of the PDU session established by the first terminal (UE1).

[0240] Step 407: If the first preset condition is not met, the SMF determines whether the type of the PDU session requested by the second terminal (UE2) and the type of the PDU session established by the first terminal (UE1) meet a second preset condition, and if the second preset condition is met, the SMF allows the request of the second terminal (UE2) to establish a PDU session, and the session establishment process continues.

[0241] Here, the second preset condition includes:

[0242] The type of the PDU session requested by the second terminal (UE2) is not the same as the type of the PDU session established by the first terminal (UE1), but is compatible.

[0243] Step 408: If the second preset condition is not met, the SMF determines whether the type of the PDU session requested by the second terminal (UE2) and the type of the PDU session established by the first terminal (UE1) meet a third preset condition, and if the third preset condition is met, the SMF allows the request of the second terminal (UE2) to establish a PDU session, the session establishment process continues, and / or, the second terminal (UE2) is identified.

[0244] Here, the third preset condition includes:

[0245] The type of the PDU session requested by the second terminal (UE2) is not the same as the type of the PDU session established by the first terminal (UE1), and is not compatible, but can be converted to an IP type.

[0246] Here, the type of the PDU session requested by the second terminal (UE2) is not the same as the type of the PDU session established by the first terminal (UE1), and is not compatible, but can be converted to an IP type, including the following:

[0247] The type of the PDU session established by the first terminal (UE1) is IPv4, and the type of the PDU session requested by the second terminal (UE2) is IPv6;

[0248] Alternatively,

[0249] The type of the PDU session established by the first terminal (UE1) is IPv6, and the type of the PDU session requested by the second terminal (UE2) is IPv4.

[0250] That is, if the type of the PDU session established by the first terminal (UE1) and the type of the PDU session requested by the second terminal (UE2) are both IP type sessions, one PDU session is of the IPv4 type and the other PDU session is of the IPv6 type, that is, they are not compatible but can be converted between IP types, the SMF allows the request of the second terminal (UE2) to establish a PDU session, and / or, identifies the second terminal (UE2).

[0251] Step 409: If the third preset condition is not met, the SMF rejects the request of the second terminal (UE2) to establish a PDU session.

[0252] Here, the third preset condition is not met, including:

[0253] The type of the PDU session requested by the second terminal (UE2) is different from and incompatible with the type of the PDU session established by the first terminal (UE1), and cannot be converted between IP types.

[0254] Here, the type of the PDU session requested by the second terminal (UE2) is different from and incompatible with the type of the PDU session established by the first terminal (UE1), and cannot be converted between IP types, including the following:

[0255] The type of the PDU session established by the first terminal (UE1) is an IP type session, and the type of the PDU session requested by the second terminal (UE2) is an Ethernet type or unstructured session;

[0256] Alternatively,

[0257] The type of the PDU session established by the first terminal (UE1) is an unstructured session, and the type of the PDU session requested by the second terminal (UE2) is an IP type session or an Ethernet type session;

[0258] Alternatively,

[0259] The type of the PDU session established by the first terminal (UE1) is an Ethernet type session, and the type of the PDU session requested by the second terminal (UE2) is an IP type session or an unstructured session.

[0260] Here, the SMF rejects the session establishment and sends a rejection message indicating that the session establishment is rejected because the PDU session type is incorrect.

[0261] Step 410: In the process of establishing the PDU session for the second terminal (UE2), the SMF performs address conversion and allocates an IP address of the same type as the PDU session established by the first terminal (UE1) to the second terminal (UE2).

[0262] Here, if the second terminal (UE2) supports the type, the PDU session is normally established, otherwise, if the second terminal (UE2) rejects the address allocated by the SMF, the session establishment process is terminated.

[0263] Here, the address conversion performed by the SMF can include the following:

[0264] The type of the PDU session established by the first terminal (UE1) is IPv4, and the type of the PDU session requested by the second terminal (UE2) is IPv6, and the SMF allocates an IP address of the same type as the PDU session established by the first terminal (UE1) to the second terminal (UE2), that is, IPv4;
