[0061] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0062] In order to facilitate understanding, first, the functional network elements involved in the present application are introduced.

[0063] The MME (Mobility Management Entity) is a core control node of the Long Term Evolution (LTE) access network, belongs to the Evolved Packet Core (EPC), and undertakes signaling processing and mobility management functions.

[0064] SAEGW (System Architecture Evolution Gateway) is a service-aware edge gateway, mainly applied in wireless communication networks, used to converge base station traffic and handle signaling interactions.

[0065] SMF / GW-C (Session Management Function / Gateway Control plane) is a combination of network elements in the 5th Generation Mobile Communication Technology (5G) core network, mainly responsible for session management and user plane function deployment.

[0066] UPF / GW-C (User Plane Function / Gateway Control plane), where UPF is an important component of the 5G core network, mainly responsible for routing and forwarding user plane data, separated from the control plane function (such as session management, authentication, etc.); GW-C is a component in the 4th Generation Mobile Communication Technology (4G) core network, used to handle signaling control, such as session establishment, authentication, etc.

[0067] UDM / HSS (Unified Data Management / Home Subscriber Server), where UDM is a unified user data management function in the 5G core network, responsible for storing user subscription information, identity verification, access authorization, etc., and supports 3rd Generation Partnership Project (3GPP) authentication and non-3GPP network access authentication; HSS is a user data management entity in the 4G core network, mainly responsible for user subscription data storage, authentication, location management, etc. In the evolution of the 5G network, part of the functions of HSS are integrated into the Unified Data Model (UDM), but some legacy data still needs to be migrated to new equipment.

[0068] In an optional embodiment, as shown in Figure 1 a gateway access method is provided, which can be applied to MME. In this embodiment, the method includes the following steps:

[0069] S110, sending a subscription information request for the target terminal to the converged network element.

[0070] The converged network element can be understood as a network element after the user data management network element in the 5G core network and the user data management network element in the 4G core network are converged. Optionally, the converged network element can be a UDM / HSS converged network element, that is, the UDM / HSS can be understood as a converged database of the 4 / 5G converged network.

[0071] The target terminal can be understood as a 4G user terminal.

[0072] The subscription information request can be understood as a request for obtaining subscription information. The subscription information can be understood as information of the target terminal subscribed in the converged network element. Optionally, the subscription information can be information of the target terminal subscribed in the UDM / HSS.

[0073] In an optional embodiment, the MME can send a subscription information request for the target terminal to the converged network element after the target terminal initiates a 4G registration request to the MME and completes user authentication of the target terminal.

[0074] S120, receiving a subscription information response sent by the converged network element; the subscription information response carries a gateway allocation identifier of a gateway to be accessed.

[0075] The gateway to be accessed can be understood as a gateway to be accessed corresponding to the target terminal. The target terminal can establish a session with the gateway to be accessed by accessing the gateway to be accessed. The gateway allocation identifier of the gateway to be accessed can be understood as an identity identifier allocated to the gateway to be accessed.

[0076] The gateway to be accessed can include a target converged gateway or a non-converged gateway.

[0077] The target converged gateway can be understood as a 4 / 5G converged gateway. Optionally, the target converged gateway can include an SMF / GW-C and an UPF / GW-C.

[0078] The non-converged gateway can be understood as a 4G gateway. Optionally, the non-converged gateway can include an SAE GW.

[0079] Optionally, the gateway to be accessed can be selected by the operator for the target terminal. In a specific implementation, the operator can select the gateway to be accessed for the target terminal according to at least one of the following information: an access user situation corresponding to the target converged gateway, a construction situation of the target converged gateway, and a user allocation situation between the SAE GW and the target converged gateway.

[0080] The access user condition corresponding to the target converged gateway can be understood as the number of accessed users, the number of remaining accessible users, the total number of accessible users, and the like corresponding to the target converged gateway.

[0081] The construction condition of the target converged gateway can be understood as the construction progress condition and the construction completion condition of the target converged gateway.

[0082] The user distribution condition between the SAEGW and the target converged gateway can be understood as the user distribution ratio between the SAEGW and the target converged gateway.

[0083] Optionally, the gateway distribution identifiers of the target converged gateway and the non-converged gateway can be distinguished by different numbers. For example, the gateway distribution identifier of the target converged gateway can be represented by 1, and the gateway distribution identifier of the non-converged gateway can be represented by 0.

[0084] S130, establishing a session between the target terminal and the to-be-accessed gateway according to the gateway distribution identifier.

[0085] In an optional embodiment, the to-be-accessed gateway can be determined according to the gateway distribution identifier. For example, when the gateway distribution identifier indicates a non-converged gateway, the to-be-accessed gateway can be determined as the SAEGW. When the gateway distribution identifier indicates a converged gateway, the to-be-accessed gateway can be determined as the target converged gateway.

[0086] In an optional embodiment, when the gateway distribution identifier indicates that the to-be-accessed gateway is a non-converged gateway, a session can be established between the target terminal and the SAEGW. When the gateway distribution identifier indicates that the to-be-accessed gateway is a converged gateway, a session can be established between the target terminal and the target converged gateway. The target converged gateway can include an SMF / GW-C and a UPF / GW-C.

[0087] For example, when the gateway distribution identifier is 0, a session can be established between the target terminal and the SAEGW. When the gateway distribution identifier is 1, a session can be established between the target terminal and the target converged gateway.

[0088] The above gateway access method can send a subscription information request for the target terminal to the converged network element, receive a subscription information response sent by the converged network element, carry the gateway distribution identifier of the to-be-accessed gateway in the subscription information response, and establish a session between the target terminal and the to-be-accessed gateway according to the gateway distribution identifier. The above process can determine the type (pure 4G gateway or 4 / 5G converged gateway) of the to-be-accessed gateway accessed by the target terminal according to the gateway distribution identifier, so as to flexibly control the number of user terminals accessing the pure 4G gateway or the 4 / 5G converged gateway, and help to realize the gradual migration of user terminals to access the 4 / 5G converged gateway.

[0089] In an optional embodiment, as shown in Figure 2 A gateway access method is provided, which can be applied to a converged network element. In this embodiment, the method comprises the following steps:

[0090] S210, receiving a subscription information request sent by the MME for the target terminal.

[0091] The subscription information request can be understood as a request for obtaining subscription information.

[0092] Optionally, the subscription information request can carry the identification information of the target terminal.

[0093] In an optional embodiment, before receiving the subscription information request sent by the MME for the target terminal, the gateway allocation identifier-carrying to-be-subscribed content can be sent to the target terminal in the case of receiving the subscription request sent by the target terminal; and the subscription information is generated according to the confirmation information returned by the target terminal for the to-be-subscribed content.

[0094] The subscription request can be understood as a request for registration and subscription. It should be understood here that the subscription request is a request for subscription in the converged network element. Optionally, the subscription request is a request for subscription in the UDM / HSS.

[0095] The to-be-subscribed content can be understood as the content to be subscribed by the user terminal.

[0096] The gateway allocation identifier can be selected by the operator for the target terminal.

[0097] S220, sending a subscription information response to the MME, so that the MME establishes a session between the target terminal and the to-be-accessed gateway according to the gateway allocation identifier of the to-be-accessed gateway carried in the subscription information response.

[0098] The above gateway access method can receive a subscription information request sent by the MME for the target terminal; send a subscription information response to the MME, so that the MME establishes a session between the target terminal and the to-be-accessed gateway according to the gateway allocation identifier of the to-be-accessed gateway carried in the subscription information response; the above process can make the MME determine the type (pure 4G gateway or 4 / 5G converged gateway) of the to-be-accessed gateway accessed by the target terminal according to the gateway allocation identifier, so that the number of user terminals accessing the pure 4G gateway or the 4 / 5G converged gateway can be flexibly controlled, which helps to realize the gradual migration of user terminals accessing the 4 / 5G converged gateway.

[0099] On the basis of the technical solutions of the above-mentioned embodiments, the application further provides another optional embodiment, in which the gateway distribution identifier of the target converged gateway can be generated according to at least one of the following information: access user information corresponding to the target converged gateway, construction information of the target converged gateway, and user distribution information between the SAEGW and the target converged gateway. The target converged gateway can include SMF / GW-C and UPF / GW-C.

[0100] The access user information corresponding to the target converged gateway can be understood as the number of users that have accessed the target converged gateway, the number of users that can access the target converged gateway, the total number of users that can access the target converged gateway, etc.

[0101] The construction information of the target converged gateway can be understood as the construction progress information of the target converged gateway, the completion information of the construction of the target converged gateway, etc.

[0102] The user distribution information between the SAEGW and the target converged gateway can be understood as the user distribution ratio between the SAEGW and the target converged gateway.

[0103] Optionally, the gateway distribution identifiers of the target converged gateway and the non-converged gateway can be distinguished by different numbers. For example, the gateway distribution identifier of the target converged gateway can be represented by 1, and the gateway distribution identifier of the non-converged gateway can be represented by 0.

[0104] On the basis of the technical solutions of the above-mentioned embodiments, the application further provides another optional embodiment, in which the gateway distribution identifier is a first distribution identifier or a second distribution identifier.

[0105] The first distribution identifier is used to indicate that the gateway to be accessed is a non-converged gateway, so that the MME establishes a session between the target terminal and the SAEGW according to the first distribution identifier.

[0106] The second distribution identifier is used to indicate that the gateway to be accessed is a converged gateway, so that the MME establishes a session between the target terminal and the target converged gateway according to the second distribution identifier. The target converged gateway includes SMF / GW-C and UPF / GW-C.

[0107] On the basis of the technical solutions of the above-mentioned embodiments, the application further provides an optional embodiment, in which the gateway access method is described in detail from the perspective of multi-party interaction.

[0108] Referring to the gateway access method shown in Figure 3 The gateway access method includes the following steps.

[0109] S310, the target terminal subscribes to the UDM / HSS and subscribes to the gateway distribution identifier of the gateway to be joined.

[0110] In an alternative embodiment, the target terminal can send a subscription request to the converged network element UDM / HSS. The converged network element UDM / HSS sends the target terminal the to-be-subscribed content. The target terminal returns confirmation information to the converged network element UDM / HSS. The converged network element UDM / HSS generates subscription information according to the confirmation information.

[0111] S320, the target terminal sends a 4G registration request to the MME.

[0112] S330, the MME performs user authentication on the target terminal.

[0113] S340, after the MME completes user authentication on the target terminal, the MME sends a subscription information request to the converged network element UDM / HSS.

[0114] S350, the converged network element UDM / HSS sends a subscription information response to the MME.

[0115] The subscription information response carries a gateway allocation identifier.

[0116] S360, the MME determines the to-be-accessed gateway according to the gateway allocation identifier.

[0117] In the case where the gateway allocation identifier indicates that the to-be-accessed gateway is a non-converged gateway, the corresponding to-be-accessed gateway is determined to be a SAE GW; in the case where the gateway allocation identifier indicates that the to-be-accessed gateway is a converged gateway, the corresponding to-be-accessed gateway is determined to be a target converged gateway; the target converged gateway includes an SMF / GW-C and a UPF / GW-C.

[0118] S370, the MME sends a session establishment request to the to-be-accessed gateway.

[0119] S380, the 4G registration and session establishment process of the target terminal is completed.

[0120] On the basis of the technical solutions of the above embodiments, the present application further provides an alternative embodiment, which details the gateway access method.

[0121] Reference is made to Figure 4The gateway access method shown includes adding a gateway allocation identifier in the 4G subscription of the fusion network element UDM / HSS. After the MME receives an access request of the 4G user terminal, the gateway allocation identifier is obtained from the fusion network element UDM / HSS after the 4G user terminal is authenticated. The MME judges whether the gateway allocation identifier is 1; if yes, the MME selects a target fusion gateway (SMF / GW-C and UPF / GW-C) for the 4G user terminal, and completes the session establishment process between the 4G user terminal and the target fusion gateway; if no, the MME selects a traditional 4G gateway (SAEGW) for the 4G user terminal, and completes the session establishment process between the 4G user terminal and the SAEGW.

[0122] It should be understood that, although each step in the flowchart involved in each of the above embodiments is shown in sequence according to the arrow, these steps are not necessarily executed in sequence according to the arrow.
