[0088] Before introducing the technical solutions of the embodiments of the present application, the related technologies are first introduced.

[0089] At present, a dual stream (DS) terminal is composed of two separate user equipment (UE), each UE has a SUPI. Two UEs can establish two independent and associated access PDU sessions, and these two sessions support steer and switch functions. Analogous to the Access Traffic Steering Switching 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 UE1's session to UE2's session, and vice versa. Therefore, the protocol data unit (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) needs to be selected as the session anchor.

[0090] At present, there are some details that need to be supplemented in the research of DualSteer. Since the two UEs are independent UEs, and each UE can independently establish a PDU session, but the PDU session type of the two UEs has not been discussed, and the session type is not specified in the route selection policy (URSP) of the two UEs. Then, when the UE requests to establish a PDU session, the data network name (DNN, Data Network Name) and single network slice selection assistance information (S-NSSAI, Single Network Slice Selection Assistance Information) requested by the UE may support multiple session types, such as IPv4, IPv6, IPv4 / v6 in IP type sessions, Ethernet type sessions and unstructured sessions. In this way, there may be a situation where the types of PDU sessions requested by the two UEs are inconsistent. When the PDU session types requested by the UE are inconsistent, the types of traffic packets on the PDU session may be different, resulting in the inability to support the steer and switch functions in DualSteer.

[0091] Therefore, the technical problem to be solved by the present application is how to ensure that the types of PDU sessions established by two UEs in a dual-stream (DualSteer) terminal meet preset conditions, such as consistency, so as to ensure the normal operation of the steer and switch functions in dualsteer.

[0092] Based on this, in an embodiment of the present application, the SMF processes the request for establishing a PDU session initiated by the second terminal according to the type of PDU session established by the first terminal and the type of PDU session requested by the second terminal.

[0093] See also Figure 1 , Figure 1 Schematic diagram of the implementation flow of the information processing method of the embodiment of the present application, applied to SMF, such as Figure 1 As shown, the method comprises step 101:

[0094] Step 101: 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, a request for establishing a PDU session initiated by the second terminal is processed.

[0095] It can be understood that the first terminal and the second terminal can form a dual stream (DS, DualSteer) terminal.

[0096] A dual stream (DS) terminal may be composed of two separate user equipments (UE), each UE having a SUPI, and the two UEs may establish two independent and associated access PDU sessions.

[0097] In some embodiments, the type of the PDU session established by the first terminal includes one of the following:

[0098] IP type session;

[0099] Ethernet type session;

[0100] Unstructured conversation.

[0101] In some embodiments, the type of the PDU session requested by the second terminal includes one of the following:

[0102] IP type session;

[0103] Ethernet type session;

[0104] Unstructured conversation.

[0105] The IP type sessions include IPv4, IPv6, IPv4 / v6, etc.

[0106] In some embodiments, the method further comprises:

[0107] Obtain the type of the PDU session established by the first terminal, and obtain the type of the PDU session requested by the second terminal.

[0108] In some embodiments, the acquiring the type of the PDU session established by the first terminal includes:

[0109] 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 the SUPI of the first terminal with the SUPI of the second terminal;

[0110] Obtain a type of a PDU session related to the SUPI of the first terminal.

[0111] Here, the first identifier may refer to a dual stream (DS, DualSteer) identifier.

[0112] In some embodiments, the obtaining the type of the PDU session requested by the second terminal includes:

[0113] According to the request for establishing a PDU session initiated by the second terminal, the type of the PDU session requested by the second terminal is obtained.

[0114] The following describes how the SMF processes the request for establishing a PDU session initiated by the second terminal in different situations.

[0115] In the 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 judgment result; based on the judgment result, it determines whether to allow the second terminal's request to establish a PDU session.

[0116] Based on this, in some embodiments, the processing of 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 includes:

[0117] If the type of the PDU session established by the first terminal is the same as the type of the PDU session requested by the second terminal, the SMF allows the second terminal's request to establish a PDU session.

[0118] See also Figure 2 , Figure 2 is a schematic diagram of an implementation flow of processing a request for establishing a PDU session initiated by a second terminal in an embodiment of the present application, such as Figure 2 As shown, it includes steps 201 to 207:

[0119] Step 201: The first terminal (UE1) has applied its own SUPI (SUPI1) to establish a PDU session, and sends a first identifier, i.e., a dual stream (DS, DualSteer) identifier, to the AMF when registering or establishing a PDU session.

[0120] 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).

[0121] Step 202: The second terminal (UE2) sends a request to establish a PDU session to the AMF; the request to establish the PDU session carries the SUPI (SUPI2) and the first identifier (DS identifier) ​​of the second terminal (UE2).

[0122] Step 203: The AMF selects the same SMF as the PDU session of the SUPI (SUPI1) of the first terminal (UE1) for the SUPI (SUPI2) of the second terminal (UE2) based on the first identifier (DS identifier) ​​sent by the first terminal (UE1) and the request to establish a PDU session sent by the second terminal (UE2).

[0123] Step 204: AMF sends a PDU session creation SM context request to SMF; the PDU session creation SM context request carries a first identifier (i.e., a DS identifier).

[0124] Here, the PDU session creation SM context request may also carry a request for establishing a PDU session initiated by the second terminal (UE2).

[0125] Step 205: The SMF obtains the type of the PDU session established by the first terminal (UE1), and obtains the type of the PDU session requested by the second terminal (UE2).

[0126] Here, SMF obtains the type of PDU session established by the first terminal (UE1), including: after SMF receives the PDU session creation SM context request sent by AMF, it identifies, based on 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), and then obtains the session information related to the SUPI (SUPI1) of the first terminal (UE1) to obtain the type of PDU session related to the SUPI (SUPI1) of the first terminal (UE1), wherein the session information includes the type of PDU session established by the first terminal (UE1) and / or the PDU session anchor point, etc.

[0127] Here, the SMF obtains the type of PDU session requested by the second terminal (UE2), including: after the SMF receives the PDU session creation SM context request sent by the AMF, according to the request for establishing the PDU session initiated by the second terminal (UE2), the SMF obtains the type of PDU session requested by the second terminal (UE2). In other words, the request for establishing the PDU session initiated by the second terminal (UE2) carries the type of PDU session requested by the second terminal (UE2).

[0128] Here, the type of the PDU session established by the first terminal (UE1) includes one of the following:

[0129] IP type session;

[0130] Ethernet type session;

[0131] Unstructured conversation.

[0132] Here, the type of the PDU session requested by the second terminal (UE2) includes one of the following:

[0133] IP type session;

[0134] Ethernet type session;

[0135] Unstructured conversation.

[0136] The IP type sessions include IPv4, IPv6, IPv4 / v6, etc.

[0137] Step 206: SMF determines whether the type of PDU session requested by the second terminal (UE2) and the type of PDU session established by the first terminal (UE1) meet the first preset condition. If the first preset condition is met, SMF allows the second terminal (UE2)'s request to establish a PDU session, and the session establishment process continues.

[0138] Here, the first preset condition includes:

[0139] 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).

[0140] 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:

[0141] The type of the PDU session established by the first terminal (UE1) is IPv4 / v6 in the IP type session, and the type of the PDU session requested to be established by the second terminal (UE2) is IPv4 / v6 in the IP type session;

[0142] or,

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

[0144] or,

[0145] The type of the PDU session established by the first terminal (UE1) is IPv6 in the IP type session, and the type of the PDU session requested to be established by the second terminal (UE2) is IPv6 in the IP type session;

[0146] or,

[0147] 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 to be established by the second terminal (UE2) is an Ethernet type session;

[0148] or,

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

[0150] 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.

[0151] Here, the first precondition is not met, including:

[0152] 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).

[0153] 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:

[0154] The type of the PDU session established by the first terminal (UE1) is an IP type session, while the type of the PDU session requested by the second terminal UE2 is an Ethernet type session or an unstructured type session;

[0155] or,

[0156] 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;

[0157] or,

[0158] The type of the PDU session established by the first terminal (UE1) is an Ethernet type session, while the type of the PDU session requested by the second terminal UE2 is an IP type session or an unstructured type session.

[0159] Here, the SMF rejects the request of the second terminal (UE2) to establish a PDU session, including: the SMF sends a rejection message for the request to create an SM context for the PDU session to the AMF, in response to the rejection of the second terminal (UE2) to establish the PDU session; the rejection message includes the reason for rejecting the second terminal (UE2) to establish the PDU session.

[0160] That is, if the type of PDU session requested by the second terminal (UE2) is inconsistent with the type of PDU session established by the first terminal (UE1), the SMF refuses the second terminal (UE2) to establish a PDU session and sends a rejection message, which indicates that the session establishment is rejected because the PDU session type is incorrect.

[0161] In an embodiment of the present application, the SMF determines that the type of PDU session requested by the second terminal (UE2) is consistent with the type of PDU session established by the first terminal (UE1), then the request of the second terminal (UE2) to establish a PDU session is allowed; if the types of the PDU sessions of the two are inconsistent, the request of the second terminal (UE2) to establish a PDU session is rejected.

[0162] 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 judgment result; based on the judgment result, determines whether to allow the second terminal's request to establish a PDU session.

[0163] Based on this, in some embodiments, the processing of 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 includes:

[0164] 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 but compatible, the SMF allows the second terminal's request to establish a PDU session.

[0165] See also Figure 3 , Figure 3 is a schematic diagram of an implementation flow of processing a request for establishing a PDU session initiated by a second terminal in an embodiment of the present application, such as Figure 3 As shown, it includes steps 301 to 308:

[0166] Step 301: The first terminal (UE1) has applied its own SUPI (SUPI1) to establish a PDU session, and sends a first identifier, i.e., a dual stream (DS, DualSteer) identifier, to the AMF when registering or establishing a PDU session.

[0167] 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).

[0168] Step 302: The second terminal (UE2) sends a request to establish a PDU session to the AMF; the request to establish the PDU session carries the SUPI (SUPI2) and the first identifier (DS identifier) ​​of the second terminal (UE2).

[0169] Step 303: The AMF selects the same SMF as the PDU session of the SUPI (SUPI1) of the first terminal (UE1) for the SUPI (SUPI2) of the second terminal (UE2) based on the first identifier (DS identifier) ​​sent by the first terminal (UE1) and the request to establish a PDU session sent by the second terminal (UE2).

[0170] Step 304: AMF sends a PDU session creation SM context request to SMF; the PDU session creation SM context request carries a first identifier (i.e., a DS identifier).

[0171] Here, the PDU session creation SM context request may also carry a request for establishing a PDU session initiated by the second terminal (UE2).

[0172] Step 305: The SMF obtains the type of the PDU session established by the first terminal (UE1), and obtains the type of the PDU session requested by the second terminal (UE2).

[0173] Here, SMF obtains the type of PDU session established by the first terminal (UE1), including: after SMF receives the PDU session creation SM context request sent by AMF, it identifies, based on 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), and then obtains the session information related to the SUPI (SUPI1) of the first terminal (UE1) to obtain the type of PDU session related to the SUPI (SUPI1) of the first terminal (UE1), wherein the session information includes the type of PDU session established by the first terminal (UE1) and / or the PDU session anchor point, etc.

[0174] Here, the SMF obtains the type of PDU session requested by the second terminal (UE2), including: after the SMF receives the PDU session creation SM context request sent by the AMF, according to the request for establishing the PDU session initiated by the second terminal (UE2), the SMF obtains the type of PDU session requested by the second terminal (UE2). In other words, the request for establishing the PDU session initiated by the second terminal (UE2) carries the type of PDU session requested by the second terminal (UE2).

[0175] Here, the type of the PDU session established by the first terminal (UE1) includes one of the following:

[0176] IP type session;

[0177] Ethernet type session;

[0178] Unstructured conversation.

[0179] Here, the type of the PDU session requested by the second terminal (UE2) includes one of the following:

[0180] IP type session;

[0181] Ethernet type session;

[0182] Unstructured conversation.

[0183] The IP type sessions include IPv4, IPv6, IPv4 / v6, etc.

[0184] Step 306: SMF determines whether the type of PDU session requested by the second terminal (UE2) and the type of PDU session established by the first terminal (UE1) meet the first preset condition. If the first preset condition is met, SMF allows the second terminal (UE2)'s request to establish a PDU session, and the session establishment process continues.

[0185] Here, the first preset condition includes:

[0186] 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).

[0187] 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 the second preset condition. If the second preset condition is met, the SMF allows the second terminal (UE2)'s request to establish a PDU session, and the session establishment process continues.

[0188] Here, the second preset condition is met, including:

[0189] 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 they are compatible.

[0190] 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:

[0191] The type of the PDU session established by the first terminal (UE1) is IPv4 / v6, and the type of the PDU session requested to be established by the second terminal (UE2) is IPv4 or IPv6;

[0192] or,

[0193] The type of the PDU session established by the first terminal (UE1) is IPv4 or IPv6, and the type of the PDU session requested to be established by the second terminal (UE2) is IPv4 / v6.

[0194] That is to say, the type of PDU session requested by the second terminal (UE2) and the type of PDU session established by the first terminal (UE1) are both IP type sessions. If the type of one PDU session is IPv4 / v6 and the type of the other PDU session is IPv4 or IPv6, it indicates that the two types are different but compatible.

[0195] 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.

[0196] Here, the second preset condition is not met, including:

[0197] 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 incompatible.

[0198] 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 is incompatible, including:

[0199] The type of the PDU session established by the first terminal (UE1) is an IP type session, while the type of the PDU session requested by the second terminal UE2 is an Ethernet type session or an unstructured type session;

[0200] or,

[0201] The type of the PDU session established by the first terminal (UE1) is an unstructured session, while the type of the PDU session requested by the second terminal UE2 is an Ethernet type session or an IP type session;

[0202] or,

[0203] The type of the PDU session established by the first terminal (UE1) is an Ethernet type session, while the type of the PDU session requested by the second terminal UE2 is an IP type session or an unstructured type session.

[0204] Here, if the type of PDU session requested by the second terminal (UE2) is inconsistent with the type of PDU session established by the first terminal (UE1) and is incompatible, the SMF refuses the second terminal (UE2) to establish a PDU session and sends a rejection message, which indicates that the session establishment is rejected because the PDU session type is incorrect.

[0205] Here, when the type of PDU session requested by the second terminal (UE2) is inconsistent with and incompatible with the type of PDU session established by the first terminal (UE1), the SMF responds to the rejection of the second terminal (UE2) to establish the PDU session by sending a rejection message for the request to create an SM context for the PDU session to the AMF; the rejection message includes the reason for rejecting the second terminal (UE2) to establish the PDU session.

[0206] In an embodiment of the present application, the SMF determines that the type of PDU session requested by the second terminal (UE2) is different from the type of PDU session established by the first terminal (UE1), but is compatible, then the establishment of the PDU session of the second terminal (UE2) is allowed; if the PDU session types of the two are different and incompatible, the establishment of the PDU session of the second terminal (UE2) is rejected.

[0207] In the third case, SMF determines whether the type of PDU session requested by the second terminal is inconsistent and incompatible with the PDU session type established by the first terminal but can perform IP type conversion, and obtains a judgment result; based on the judgment result, determines whether to allow the second terminal's request to establish a PDU session.

[0208] Based on this, in some embodiments, the processing of 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 includes:

[0209] If the type of PDU session established by the first terminal is different from and incompatible with the type of PDU session requested by the second terminal, but IP type conversion can be performed, the SMF allows the second terminal's request to establish a PDU session, and / or the SMF identifies the second terminal.

[0210] In some embodiments, the processing, 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, the request for establishing the PDU session initiated by the second terminal includes:

[0211] If the type of PDU session established by the first terminal is different from the type of PDU session requested by the second terminal and is incompatible, and IP type conversion cannot be performed, the SMF rejects the second terminal's request to establish a PDU session.

[0212] In some embodiments, the method further comprises:

[0213] An IP address of the same type as the PDU session established by the first terminal is allocated to the second terminal.

[0214] In some embodiments, the SMF rejects the request of the second terminal to establish a PDU session, including:

[0215] Send a rejection message for the SM context creation request for the PDU session to the AMF; the rejection message includes the reason for rejecting the establishment of the PDU session by the second terminal.

[0216] See also Figure 4 , Figure 4 is a schematic diagram of an implementation flow of processing a request for establishing a PDU session initiated by a second terminal in an embodiment of the present application, such as Figure 4 As shown, it includes steps 401 to 410:

[0217] Step 401: The first terminal (UE1) has applied its own SUPI (SUPI1) to establish a PDU session, and sends a first identifier, i.e., a dual stream (DS, DualSteer) identifier, to the AMF when registering or establishing a PDU session.

[0218] 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).

[0219] Step 402: The second terminal (UE2) sends a request to establish a PDU session to the AMF; the request to establish the PDU session carries the SUPI (SUPI2) and the first identifier (DS identifier) ​​of the second terminal (UE2).

[0220] Step 403: The AMF selects the same SMF as the PDU session of the SUPI (SUPI1) of the first terminal (UE1) for the SUPI (SUPI2) of the second terminal (UE2) based on the first identifier (DS identifier) ​​sent by the first terminal (UE1) and the request to establish a PDU session sent by the second terminal (UE2).

[0221] Step 404: AMF sends a PDU session creation SM context request to SMF; the PDU session creation SM context request carries a first identifier (i.e., a DS identifier).

[0222] Here, the PDU session creation SM context request may also carry a request for establishing a PDU session initiated by the second terminal (UE2).

[0223] Step 405: The SMF obtains the type of the PDU session established by the first terminal (UE1), and obtains the type of the PDU session requested by the second terminal (UE2).

[0224] Here, SMF obtains the type of PDU session established by the first terminal (UE1), including: after SMF receives the PDU session creation SM context request sent by AMF, it identifies, based on 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), and then obtains the session information related to the SUPI (SUPI1) of the first terminal (UE1) to obtain the type of PDU session related to the SUPI (SUPI1) of the first terminal (UE1), wherein the session information includes the type of PDU session established by the first terminal (UE1) and / or the PDU session anchor point, etc.

[0225] Here, the SMF obtains the type of PDU session requested by the second terminal (UE2), including: after the SMF receives the PDU session creation SM context request sent by the AMF, according to the request for establishing the PDU session initiated by the second terminal (UE2), the SMF obtains the type of PDU session requested by the second terminal (UE2). In other words, the request for establishing the PDU session initiated by the second terminal (UE2) carries the type of PDU session requested by the second terminal (UE2).

[0226] Here, the type of the PDU session established by the first terminal (UE1) includes one of the following:

[0227] IP type session;

[0228] Ethernet type session;

[0229] Unstructured conversation.

[0230] Here, the type of the PDU session requested by the second terminal (UE2) includes one of the following:

[0231] IP type session;

[0232] Ethernet type session;

[0233] Unstructured conversation.

[0234] The IP type sessions include IPv4, IPv6, IPv4 / v6, etc.

[0235] Step 406: SMF determines whether the type of PDU session requested by the second terminal (UE2) and the type of PDU session established by the first terminal (UE1) meet the first preset condition. If the first preset condition is met, SMF allows the second terminal (UE2)'s request to establish a PDU session, and the session establishment process continues.

[0236] Here, the first preset condition includes:

[0237] 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).

[0238] 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 the second preset condition. If the second preset condition is met, the SMF allows the second terminal (UE2)'s request to establish a PDU session, and the session establishment process continues.

[0239] Here, the second preset condition is met, including:

[0240] 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 they are compatible.

[0241] 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 the third preset condition. If the third preset condition is met, the SMF allows the second terminal (UE2)'s request to establish a PDU session, the session establishment process continues, and / or the second terminal (UE2) is identified.

[0242] Here, the third precondition is met, including:

[0243] 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), but IP type conversion can be performed.

[0244] 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), but IP type conversion can be performed, including the following:

[0245] 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;

[0246] or,

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

[0248] That is to say, if the type of PDU session established by the first terminal (UE1) and the type of PDU session requested by the second terminal (UE2) are both IP type sessions, one PDU session type is IPv4 and the other PDU session type is IPv6, that is, they are incompatible, but IP type conversion can be performed, then the SMF allows the second terminal (UE2)'s request to establish a PDU session, and / or identifies the second terminal (UE2).

[0249] 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.

[0250] Here, the third precondition is not met, including:

[0251] 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 IP type conversion cannot be performed.

[0252] 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), and is incompatible, and IP type conversion cannot be performed, including the following:

[0253] 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 an unstructured type session;

[0254] or,

[0255] 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;

[0256] or,

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

[0258] Here, SMF rejects the session establishment and sends a rejection message, which indicates that the session establishment is rejected because the PDU session type is incorrect.

[0259] Step 410: During the process of establishing a PDU session at the second terminal (UE2), the SMF performs address conversion and allocates an IP address of the same type as the PDU session established at the first terminal (UE1) to the second terminal (UE2).

[0260] Here, if the second terminal (UE2) supports this type, the PDU session is established normally, otherwise, if the second terminal (UE2) rejects the address allocated by the SMF, the session establishment process is terminated.

[0261] Here, SMF performs address translation, which may include the following:

[0262] 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. The SMF allocates an IP address of the same type as the PDU session established by the first terminal (UE1), i.e., IPv4, to the second terminal (UE2);

[0263] or,

[0264] The type of PDU session established by the first terminal (UE1) is IPv6, while the type of PDU session requested by the second terminal (UE2) is IPv4. SMF allocates the same IP address, i.e., IPv6, to the second terminal (UE2) as the type of PDU session established by the first terminal (UE1).

[0265] In an embodiment of the present application, when the SMF determines that the type of PDU session requested by the second terminal (UE2) is different from and incompatible with the type of PDU session established by the first terminal (UE1), but the IP type conversion can be performed, 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) to achieve conversion between IPv4 and IPv6 addresses.

[0266] In the embodiment of the present application, the following advantages are possessed:

[0267] (1) Provide a technical solution for ensuring that the types of PDU sessions established by two terminals in a dual-stream (DualSteer) terminal are consistent. Specifically, according to the type of PDU session established by the first terminal and the type of PDU session requested by the second terminal, the request for establishing a PDU session initiated by the second terminal is processed.

[0268] In the embodiment of the present application, by ensuring to the greatest extent that the two PDU session types established by the two UEs in the dual-stream terminal (DualSteer Device) meet the preset conditions, it is ensured that the sessions of the two UEs can perform steer and switch functions, thereby ensuring the normal operation and operation of the multi-stream transmission equipment and reducing the waste of network resources.
