Background technique

In a 5G network, a single protocol data unit (Protocol Data Unit, PDU) session (Session) can use multiple access technologies to transmit data, that is, a multi-access (Multi-Access PDU, MA PDU) Session. In other words, a single PDU Session can use multiple access types to transmit data. For example, a single PDU Session can use the access type corresponding to the 3rd Generation Partnership Project (The3rd Generation Partnership Project, 3GPP) and the Non-3GPP access type to transmit data at the same time. Using this technical solution can not only enable the terminal equipment to obtain a higher transmission rate and save more charges, but also enable the user plane function (User Plane Function, UPF) to more efficiently use N3GPP radio resources to increase the transmission rate and spectrum utilization rate. However, due to the limited radio resources (Uu) and core network resources (N3), UPF and Access Network (AN) nodes cannot always maintain 3GPP access types and Non-3GPP access types corresponding to the access ( Access). When there is no data transmission on an access for a period of time, SMF will deactivate the resources on the access. That is, the Uu and N3 interface resources are released, but the context of the MA-PDU Session is retained in the terminal device, SMF and UPF.

The technical solution in this application will be described below in conjunction with the drawings.

Fig. 1 is a schematic block diagram of a method for transmitting multicast services and a wireless communication system architecture 100 according to the present application. As shown in FIG. 1, the system architecture 100 includes a terminal device 110, an access network device 120, a core network device 130, and a data network 160 (data network, DN), where the core network device 130 includes a management device 140 and a gateway Device 150.

The terminal device 110 can be used to connect to the access network device 120 deployed by the operator through a wireless air interface, and then to the data network through the core network device 130; the access network device 120 is mainly used to implement wireless physical layer functions, resource scheduling, and wireless Functions such as resource management, wireless access control, and mobility management; the core network device 130 may include a management device 140 and a gateway device 150. The management device 140 is mainly used for device registration, security authentication, mobility management and location management of terminal devices, etc. , The gateway device 150 is mainly used to establish a channel with the terminal device, and forward data packets between the terminal device and the external data network on the channel; the data network 160 can correspond to a variety of different service domains, such as the IP multimedia subsystem ( IP multimedia subsystem, IMS), Internet, Internet protocol television (IPTV), other operator business domains, etc., are mainly used to provide a variety of data service services for terminal devices, which can include, for example, servers (including provisioning groups). Network equipment such as servers for broadcasting services, routers, and gateways. For example, for a terminal that wants to receive IP multicast service data packets, it needs to request to join/exit the multicast IP address corresponding to a certain multicast service through the group management protocol to start receiving/ending the multicast service. The IP multicast group The management protocol has the IGMP protocol in IPv4, and the corresponding MLD protocol in IPv6.

It should be noted that FIG. 1 is only an exemplary architecture diagram. In addition to the functional units shown in FIG. 1, the network architecture may also include other functional units or functional entities, which are not limited in the embodiment of the present application.

For example, the communication network shown in Figure 1 is a 5G network communication system.

The aforementioned terminal equipment may be user equipment (UE). For example, mobile phones and computers can also be cellular phones, cordless phones, session initiation protocol (SIP) phones, smart phones, wireless local loop (WLL) stations, personal digital assistants (personal digital assistants) , PDA), computers, laptop computers, handheld communication equipment, handheld computing equipment, satellite wireless equipment, wireless modem cards, TV set top boxes (STB), customer premise equipment (customer premise equipment, CPE) and / Or other equipment used to communicate on the wireless system.

The aforementioned access network equipment may be an access network (AN)/radio access network (RAN) equipment, and a network composed of multiple 5G-AN/5G-RAN nodes. The 5G-AN/ 5G-RAN nodes can be: access point (AP), next-generation base station (NR NodeB, gNB), central unit (CU) and distributed unit (DU) separated form gNB, Transmission receive point (TRP), transmission point (TP) or some other access node.

The aforementioned core network equipment may include: access and mobility management function (AMF), session management function (session management function, SMF), policy control function (PCF), user plane function (user plane function) , UPF) and other functional units, these functional units can work independently, can also be combined to achieve certain control functions, such as: AMF, SMF and PCF can be combined together as a management device to complete the access authentication of terminal equipment , Security encryption, location registration and other access control and mobility management functions, as well as session management functions such as the establishment, release and modification of user plane transmission paths, as well as analysis of some slice-related data (such as congestion) and terminal equipment related functions As a gateway device, UPF mainly completes the routing and forwarding of user plane data, such as: responsible for data message filtering, data transmission/forwarding, rate control, and charging information generation for terminal devices.

The network architecture described in Figure 2 can support the PDU connection service, which refers to the service of exchanging PDU data packets between the UE and the DN. For example, as shown in FIG. 1, the terminal device 100 and the data network 160 exchange PDU data packets. The terminal device realizes the PDU connection service by initiating the establishment of a PDU session. After a single PDU session is established, a data transmission channel between the UE and the DN is established. In the network architecture described in FIG. 2, a single protocol data unit (Protocol Data Unit, PDU) session (Session) can use multiple access technologies to transmit data. In other words, a single PDU Session can use multiple access types to transmit data. In other words, a single PDU Session can transmit data on access channels corresponding to multiple access types. For example, the multiple access types may include 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) access types and non-3GPP (Non-3GPP, N3GPP) access types. 3GPP access types may include Long Term Evolution (LTE) access types and New Radio (NR) access types. The non-3GPP access type may include the wireless local area network (Wireless LAN, WLAN) access type. For example, in the embodiment of the present application, this PDU Session established using multiple access types is called a Multi-Access (Multi-Access PDU, MA PDU) Session. Through Multi-Access PDU Session, terminal equipment can obtain a higher transmission rate, which can save more charges; the network can use N3GPP wireless resources more efficiently, and improve transmission rate and spectrum utilization.

Fig. 3 is a schematic block diagram of an MA-PDU session in an embodiment of the present application.

A MA PDU Session is established between the terminal device and the server. This MA PDU Session can use 3GPP access type and non-3GPP access type for data transmission. Specifically, while the terminal equipment is connected to one UPF through the N3 interface through the access network equipment corresponding to the 3GPP access type, the terminal equipment is connected to another UPF through the N3 interface through the access network equipment corresponding to the non-3GPP access type. . The two UPFs can be connected to an anchor UPF through the N9 interface to manage the two UPFs. The anchor UPF can be connected to the server through the N6 interface. More specifically, when the terminal device is connected to the UPF through an access network device corresponding to a non-3GPP access type, it may be connected to the UPF through a non-3GPP Interworking Function (N3IWF). Thus, after the application sends data to the terminal device, the terminal device can send data to the UPF through the MA PDU Session on the access corresponding to the 3GPP access type and/or the access corresponding to the non-3GPP access type.

However, due to the limited radio resources (Uu) and core network resources (N3), the UPF and AN cannot always maintain the resources on the access (Access) corresponding to the 3GPP access type and the Non-3GPP access type. When there is no data transmission on an access for a period of time, SMF will deactivate the resources on the access. That is, the Uu and N3 interface resources are released, but the context of the MA-PDU Session is retained in the terminal device, SMF and UPF.

FIG. 2 is a schematic flowchart of a method 200 for activating resources according to an embodiment of the present application. The network elements involved in the method 200 include terminal devices, access network devices corresponding to at least one access type, AMF, and SMF. For ease of understanding, the following takes the access network device corresponding to the at least one access type including a first access network device and a second access network device as an example, and the method 200 is described in detail from the perspective of a terminal device.

In other words, when the user plane of the first session is activated, the first session may use accesses corresponding to multiple access types to transmit data.

The method 200 includes some or all of the following content:

S210. The terminal device sends instruction information to the AMF, where the instruction information is used to instruct to activate a user plane of at least one of the multiple access types used by the first session. For example, the terminal device generates and sends instruction information to the AMF. Specifically, when the terminal device has uplink data to be sent, the terminal device may be triggered to generate and send the indication information to the AMF.

In the embodiment of the present application, multiple access types may be used when the first session is established, and the user plane of the multiple access types used in the first session is deactivated, and the terminal device After the AMF sends the indication information, and then the user plane of the at least one access type of the first session is activated, the first session may use the access data corresponding to the at least one access type transmission.

Optionally, the terminal device sends the indication information to the AMF through an access network device corresponding to any one of the at least one access type. For example, the terminal device sends the indication information to the AMF through the first access network device corresponding to the first access type in the at least one access type. For another example, the terminal device may send the indication information through a second access network device corresponding to a second access type among the at least one access type. For example, the first access network device and the second access network device may be respectively an access network device and a non-3GPP (Non-3GPP) belonging to the 3rd Generation Partnership Project (3GPP). , N3GPP) access network equipment. The access network equipment to which 3GPP belongs may include Long Term Evolution (LTE) access network equipment and New Radio (NR) access network equipment. The access network equipment to which the non-3GPP belongs may include a wireless local area network (Wireless LAN, WLAN) access network equipment.

In the embodiment of the present application, through the instruction information, the terminal device can activate the resource on the access corresponding to at least one access type in one activation process. In other words, the technical solutions of the embodiments of the present application can be applied to the Multi-Access (Multi-Access PDU, MA PDU) Session technology. Especially when the at least one access type is multiple access types, signaling overhead and time delay can be effectively reduced.

The terminal device may generate the indication information based on the session identifier of the first session and the at least one access type.

Optionally, the method 100 may further include: the terminal device determining the at least one access type.

Optionally, the terminal device may determine the at least one access type according to the first session.

For example, when the identifier of the first session is a multiple access protocol data unit MA PDU session identifier, the terminal device determines that the at least one access type is multiple access types; otherwise, the terminal device determines the At least one access type is one access type.

For another example, the terminal device determines the access type used by the first session as the at least one access type. For example, the terminal device determines multiple access types used when establishing the first session as the at least one access type. That is, the indication information is used to indicate the activation of the user plane of the multiple access types used when the first session is established.

Optionally, the terminal device may also determine the at least one access type according to the data to be transmitted.

For example, when the protocol used for the data to be transmitted is Multi-Path Transmission Control Protocol (MPTCP), the terminal device determines that the at least one access type is multiple access types; otherwise, The terminal device determines that the at least one access type is one access type.

For another example, the terminal device may determine the at least one access type according to the access type used by the data to be transmitted. Specifically, the terminal device may determine the target quality of service (QoS) flow used by the data to be transmitted; then the terminal device may determine the access type used by the target QoS flow as the at least one access type Entry type.

Optionally, the terminal device may also determine the access type indicated by the mode information in the filtering data steering switching and splitting (Access Traffic Steering Switching and Splitting, ATSSS) rule as the at least one access type. Specifically, the mode information may be switching mode information. For example, the switching mode information indicates that when the first session is switched from using the first access type to using the second access type, the terminal device will switch the first access type to the second access type. The second access type is determined to be the at least one access type. For another example, the mode information is communication mode information. For example, when the communication mode information indicates that the first access type and the second access type can be used to transmit data, the terminal device sets the first access mode and the The second access mode is determined to be the at least one access type. Optionally, the multiple access types used when the first session is established may include the first access type and the second access type.

Optionally, the method 100 may further include:

The terminal device determines the first session.

Optionally, the terminal device may determine the first session by filtering a filter in a data steering switching and splitting (Access Traffic Steering Switching and Splitting, ATSSS) rule. Specifically, the terminal device may determine the first session according to the IP address and/or port number of the data to be transmitted, and the filter in the ATSSS rule, where the ATSSS rule may include each of the multiple sessions. An IP address and/or port number corresponding to each session, each of the multiple sessions may use at least one access type for data transmission.

S220: After receiving the indication information sent by the terminal device, the AMF sends the indication information to a session management function (Session Management Function, SMF).

S230: After receiving the indication information, the SMF may activate the resources of the first session on the access corresponding to the at least one access type according to the indication information.

S240. After the SMF activates the resource on the access corresponding to the at least one access type, the SMF sends first information to the AMF, where the first information may include the at least one Two types of access types, PDU session identifiers, N2 Session Management (SM) containers (Containers) corresponding to each type of access, where each N2 SM Container contains the corresponding access network equipment transmission for the access type The tunnel ID (Tunnel ID) and QoS parameters of the target end (UPF) of the uplink data. For example, if there are two access types (Access types), there are two Access type-N2 SM Containers.

In other words, after receiving the first information, the AMF determines which access network device or devices to send an N2 message (Message) according to the first information, which contains the identifier of the first session and the corresponding N2 SM Container.

Taking the AMF needing to send two N2 messages to the access network devices corresponding to the two access types as an example, the method 200 may further include:

For example, in other alternative embodiments, the at least one access type is one access type, that is, the first session uses one access type for data transmission. For another example, the at least one access type is three access types, and the three access types correspond to three access network devices.

FIG. 4 is an example of the method 300 in the process of triggering a service request by the terminal device of the method 200 shown in FIG. 3.

As shown in FIG. 4, the method 300 may include:

FIG. 5 is a schematic flowchart of another method 400 for activating resources according to an embodiment of the present application. The network elements involved in the method 400 include terminal equipment, access network equipment corresponding to at least one access type, AMF, and SMF. For ease of understanding, the following takes the access network device corresponding to the at least one access type including the first access network device and the second access network device as an example, and the method 400 is described in detail from the perspective of UPF. . The method 400 is applied to the first session established using multiple access types and the user plane is deactivated. In other words, the terminal device, SMF, and UPF retain the context information of the first session established using the multiple access types, that is, the first session has been established and the user plane is deactivated. In other words, when the user plane of the first session is activated, the first session may use accesses corresponding to multiple access types to transmit data.

As shown in FIG. 5, the method 400 may include:

S410. The UPF sends instruction information to the SMF, where the instruction information is used to instruct to activate a user plane of at least one of the multiple access types used by the first session. For example, the UPF generates and sends instruction information to the SMF. Specifically, when the UPF receives the downlink data of the terminal device, it may trigger the UPF to generate and send the indication information to the SMF.

In the embodiment of the present application, through the instruction information, the UPF can activate the resources on the access corresponding to at least one access type in one activation process. In other words, the technical solutions of the embodiments of the present application can be applied to the Multi-Access (Multi-Access PDU, MA PDU) Session technology. Especially when the at least one access type is multiple access types, signaling overhead and time delay can be effectively reduced.

The UPF may generate the indication information based on the session identifier of the first session and the at least one access type.

Optionally, the method 400 may further include: the UPF determining the at least one access type.

Optionally, the UPF may determine the at least one access type according to the first session.

For example, when the identifier of the first session is a multiple access protocol data unit MA PDU session identifier, the UPF determines that the at least one access type is multiple access types, otherwise the UPF determines the at least one One access type is one access type.

For another example, the UPF determines the access type used by the first session as the at least one access type.

Optionally, the UPF may also determine the access type indicated by the mode information in the filtering data steering switching and splitting (Access Traffic Steering Switching and Splitting, ATSSS) rule as the at least one access type. Specifically, the mode information may be switching mode information. For example, the switching mode information indicates that when the first session is switched from using the first access type to using the second access type, the UPF will change the second access type. The access type is determined to be the at least one access type. For another example, the mode information is communication mode information.
