detailed description

FIG. 1 is a network architecture diagram of an existing terminal accessing an IPTV network. As shown in FIG. 1 , in the prior art, a UE sets a set top box (STB) and a residential gateway (RG). The wired network includes: an access network (AN) device and a broadband network gateway (BNG). The RG can access the IPTV network through a wired network. After the RG accesses the IPTV network, the STB connected to the RG can obtain data provided by the IPTV network through the RG.

2 is a flow chart of a method for an existing terminal to access an IPTV network. As shown in FIG. 2, the RG interacts with a dynamic host configuration protocol (DHCP) server in the IPTV network through a wired network to access the IPTV network. specifically:

S101. The RG sends a DHCP discovery message to the BNG.

The DHCP discovery (discover) message is used to request the DHCP server to authenticate the RG.

S102. The BNG sends a DHCP discovery message to the DHCP server.

The DHCP discovery message includes: a line identification (Line ID) of the RG.

The Line ID of the RG is stored in the BNG, and the Line ID is the identifier of the RG in the IPTV network. Therefore, before the BNG sends the DHCP discovery message to the DHCP server, the Option 82 sub-option is added to the DHCP discovery message. The Option 82 sub-option includes the Line ID of the RG. That is to say, the DHCP discovery message sent by the BNG to the DHCP server includes: the Line ID of the RG.

S103. The DHCP server interacts with an authentication server of the IPTV network to authenticate the RG.

For example, the DHCP server may send an authentication request message to the authentication server, where the authentication message includes: a Line ID of the RG. After receiving the authentication request message, the authentication server may query the local database according to the Line ID of the RG carried in the authentication request message. When the Line ID of the RG exists in the local database, it indicates that the RG can use the service of the IPTV network, that is, the RG authentication. In this scenario, the authentication server can send an authentication pass message to the DHCP server. The authentication pass message is used to indicate that the RG authentication is passed. When the RG authentication is passed, the DHCP server may further perform the subsequent step S104.

If the authentication server does not query the Line ID of the RG in the local database, the RG cannot use the service of the IPTV network, that is, the RG authentication fails. In this scenario, the authentication server can send an authentication failure message to the DHCP server. The authentication failure message is used to indicate that the RG authentication fails. When the RG authentication fails, the DHCP server may send a DHCP message to the RG indicating that the RG authentication failed. After receiving the DHCP message, the RG can re-initiate the access procedure. That is, step S101 is re-executed. This flow is not shown in FIG.

In a specific implementation, the authentication server of the IPTV network may be, for example, an authentication, authorization, and accounting (AAA) server.

S104. The DHCP server sends a DHCP offer message to the RG.

The DHCP offer (Offer) message includes: an internet protocol (IP) address assigned by the DHCP server to the RG, that is, an IP address of the RG in the IPTV network. Thus, in some embodiments, the IP address may also be referred to as an IP address assigned by the IPTV network to the RG.

In a specific implementation, the DHCP server may send the DHCP providing message to the RG through the BNG, and details are not described herein.

S105. The RG sends a DHCP request message to the BNG.

The DHCP request message is used to query the DHCP server whether the allocated IP address is available. This process is used to prevent the DHCP server from assigning the same IP address to the two RGs, which prevents the RG from using the IP address to access the IPTV network.

S106. The BNG sends a DHCP request message to the DHCP server.

Before the BNG sends the DHCP request message to the DHCP server, the Option 82 sub-option is added to the DHCP request message. The Option 82 sub-option includes the Line ID of the RG.

S107. The DHCP server sends a DHCP confirmation message to the RG.

The DHCP acknowledgement message is used to notify the RG that the assigned IP address is available.

When the DHCP server determines that the IP address assigned to the RG does not conflict with the IP addresses of other RGs, the DHCP server determines that the IP address is available. In this scenario, the DHCP server can send a DHCP confirmation message to the RG through the BNG. The DHCP acknowledgement (Ack) message includes: an IP address assigned by the DHCP server to the RG, to notify the RG that the assigned IP address is available through the IP address. It should be noted that if the DHCP server determines that the IP address assigned to the RG conflicts with the IP address of the other RG, it is determined that the IP address is unavailable. In this scenario, the DHCP server can send a DHCP message to the RG indicating that the IP address is not available. After receiving the DHCP message, the RG can re-initiate the access procedure. That is, step S101 is re-executed. This flow is not shown in FIG.

So far, the process of RG accessing the IPTV network through the wired network is completed. After the RG accesses the IPTV network, the STB connected to the RG can obtain data provided by the IPTV network through the RG and provide the data to the user.

However, the above prior art only relates to how the RG accesses the IPTV network through the wired network, and does not relate to how the RG accesses the IPTV network in other networks (for example, a wireless network).

When the network shown in FIG. 3 is a non-trusted non-3GPP network, the access network device may be a non-3GPP Interworking Function (N3IWF) network element. When the network shown in FIG. 3 is a trusted non-3GPP access network, the access network device may be a trusted access gateway. When the network shown in FIG. 3 is a wireless network, the access network device may be a wireless access network device. The radio access network device mentioned herein is an access device that the terminal accesses to the mobile communication system by using a wireless device, and may be a network side NodeB, an evolved network side eNodeB, a network side in a 5G mobile communication system, and a future mobile. The specific technology and the specific device configuration adopted by the radio access network device are not limited in the embodiment of the present application.

The UPF network element is used to transmit user plane data. The AMF network element is used to manage whether the terminal can access the network. The SMF network element is used to manage the session connection established by the terminal through the network, and each session connection is used to transmit the user plane data of the terminal. The PCF network element is used to provide a policy for the terminal to access the network, such as a quality of service (QoS) policy. The UDM network element is used to store subscription data of the terminal.

The following is a detailed description of how the terminal accesses the service network through some embodiments based on the architecture of the network shown in FIG. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments. In order to facilitate the distinction between the network and the service network shown in FIG. 3, the network shown in FIG. 3 is referred to as a network used by the terminal to access the service network, and is referred to as an access network.

In this embodiment of the present application, after the terminal completes registration in the access network, the session may be established in the access network. The terminal can then access the service network through the session. That is, the process of the terminal accessing the service network includes two parts: establishing a session part and accessing the service network part. It can be understood that the process of registering the terminal in the access network can refer to the prior art, and details are not described herein again.

In the process of the terminal accessing the service network, the following network elements are involved: a session management network element (for example, an SMF network element) and a user plane network element (the intermediate transmission network element when the terminal transmits data through the access network and the service network, for example, : UPF network elements, access network devices, etc., policy control network elements (such as PCF network elements), data management network elements (such as UDM network elements, unified data repository (UDR) network elements), access management network Yuan (for example, AMF network element).

The following describes how the terminal establishes a session in the access network. FIG. 4 is a flowchart of a method for accessing a service network according to an embodiment of the present application. As shown in Figure 4, the method includes:

S201. The terminal sends a session establishment request message to the session management network element.

S202. The session management network element obtains verification information of the terminal in the service network, and the verification message is used by the terminal to access the service network.

Specifically, when determining to establish a session, the terminal may send a session establishment request to the session management network element to request the session management network element to establish a session. In this way, the terminal can utilize the session to perform data transmission with the service network. The session request message may carry the first identifier information of the terminal and the identifier information of the service network. The first identification information of the terminal mentioned herein may be, for example, an ID of the terminal, an international mobile subscriber identification number (IMSI) of the terminal, a generic public subscription identifier (GPSI) of the terminal, and a terminal. One or more of the Mobile Subscriber International ISDN number (MSISDN). The identification information of the service network referred to here may be, for example, the ID of the service network and/or the name of the service network. In some embodiments, the name of the service network may also be referred to as a data network name (DNN).

In a possible implementation manner, the terminal may determine to establish a session when completing the registration process of accessing the network. Alternatively, the terminal may determine to establish a session when receiving data of the service network sent by the client. For example, the terminal may determine to establish a session when receiving an internet group management protocol (IGMP) message sent by the client. The client mentioned here can be understood as a device that obtains a service provided by a service network through a terminal.

After receiving the session establishment request message sent by the terminal, the session management network element may establish a session for the terminal. For details on how the session management network element establishes a session for the terminal, refer to the prior art, and details are not described herein.

In this embodiment, the session management network element may obtain the verification information of the terminal in the service network during the process of establishing a session for the terminal. In this way, when the terminal accesses the service network, the service network can authenticate the terminal based on the verification information. The verification information of the terminal in the service network may be, for example, the line ID of the terminal, the media access control (MAC) address of the terminal, the type information of the terminal, the level information of the terminal, and the time used by the terminal to access the service network. User name information, etc. The Line ID may include, for example, a circuit ID or a remote ID. The type information and the level information mentioned above may be specifically determined according to the setting of the communication system, which is not limited in this embodiment of the present application.

This embodiment does not limit the manner in which the session management network element obtains the verification information of the terminal in the service network. In a possible implementation manner, the local database of the session management network element stores the verification information of the terminal in the service network. Therefore, the session management network element can obtain the verification information of the terminal in the service network from the local database. For example, the local identifier of the session management network element may store the first identification information of the terminal and the mapping relationship of the verification information of the terminal in the service network. Therefore, the session management network element can search for the verification information corresponding to the first identifier (that is, the verification information of the terminal in the service network) in the local database according to the first identifier information of the terminal carried in the session establishment request message.

In another possible implementation manner, the session management network element may obtain the verification information from other network elements storing the verification information of the terminal in the service network. The other network elements mentioned herein may be, for example, a policy control network element, or a data management network element, or an access management network element. For example, the session management network element may send a query request to other network elements, where the query request may include: first identifier information of the terminal. The other network element searches for the verification information corresponding to the first identification information of the terminal (that is, the verification information of the terminal in the service network) in the local database according to the first identification information of the terminal. Then, the other network element may return a query response message to the session management network element, where the query response message may include: verification information of the terminal in the service network.

In this implementation manner, the foregoing network element storing the verification information of the terminal in the service network may further receive the verification information of the terminal in the service network before performing the foregoing method embodiment, and use the verification information as the terminal. information. In a specific implementation, the service network management system network element on the service network side or the access network management system network element on the access network side may generate verification information of the terminal in the service network when the user subscribes to the service of the service network, and The network element that needs to store the verification information sends a subscription request message to notify the network element terminal that the service of the service network has been subscribed. The subscription request message may include: authentication information of the terminal in the service network, and first identification information of the terminal. After receiving the subscription request message, the network element that needs to store the verification information may store the verification information as information of the terminal. Taking the network element that needs to store the verification information as a data management network element, after receiving the subscription request, the data management network element may search for the subscription information of the terminal stored in the local database based on the first identification information of the terminal. The verification information of the terminal in the service network is added to the subscription information of the terminal. Taking the policy control network element as an example, after receiving the subscription request, the policy control network element may search for the policy information of the terminal stored in the local database based on the first identification information of the terminal, and verify the terminal in the service network. Information is added to the policy information for the terminal.

It can be understood that when the operation of generating the verification information of the terminal in the service network is performed by the access network management system network element, the service network management system network element can access the network management system network when the user subscribes to the service of the service network. The element sends a subscription request message to trigger the access network management system network element to perform the operation of generating the verification information of the terminal in the service network by notifying the access network management system network element that the terminal has subscribed to the service of the service network. . Correspondingly, the access network management system network element may send a subscription response message to the service network management system network element after generating the verification information of the terminal in the service network, where the message may include: the terminal is in the service network. Verification information in .

It can be understood that the subscription request message and the subscription response message mentioned above are only an indication and do not constitute a limitation on the message. In a specific implementation, the subscription request message may be replaced by any other message including the verification information of the terminal in the service network and the first identification information of the terminal, where the subscription response message may be verified by any other terminal including the service network. The message is replaced by information, which is not limited. The following provides an explanation of the method provided by the embodiment of the present application by using a subscription request message and a subscription response message as an example.

The network element of the service network management system mentioned above may be a business operation support system (BOSS) network element of the service network, or a business support system (BSS) network element of the service network, or media entertainment. A media entertainment middleware (MEM) network element, or a subscriber management system (SMS) network element of a service network. The network element of the access network management system mentioned above may be a network management system (NMS) network element that accesses the network, or an operation support system (OSS) network element that accesses the network, or The BSS network element of the access network, or the unified data repository (UDR) network element of the access network, or the access management function (AMF) network element of the access network, or access A network management session (SMF) network element or a policy control function (PCF) network element that accesses the network.

In the above two manners of generating authentication information of the terminal in the service network, the service network management system network element may be after generating the verification information of the terminal in the service network, or the service network management system network element is managed by receiving the access network. After receiving the authentication information of the terminal in the service network, the system may send the verification information of the terminal in the service network to the network element of the other information in the service network for storing the terminal. For example, the service network management system network element is a BOSS network element, and other network elements for storing information of the terminal are SMS network elements.

Further, the session management network element may further obtain the identification information of the service network according to the session establishment request message in the process of establishing a session for the terminal. Further, the session management network element may determine, according to the identification information of the service network, a policy control network element that provides a policy for the service network. In this way, the session management network element can notify the policy control network element terminal to obtain the service from the service network. For example, the session management network element may send a notification message to the policy control network element, where the notification message carries the identification information of the service network and the first identification information of the terminal. After receiving the notification message, the policy control network element may determine that the terminal will obtain the service from the service network. Correspondingly, the policy control network element may send the policy of the service network corresponding to the terminal to the session management network element. The policy of the service network mentioned herein may include, for example, a quality of service (QoS) of data of the service network.

After completing the session establishment for the terminal, the session management network element may send a session establishment response message to the terminal to notify the terminal that the session has been established. So far, the process of establishing a session part of the terminal access service network is completed.

A possible implementation manner, if the session establishment request message includes indication information for instructing the terminal to obtain an IP address from the service network, the session management network element does not perform IP allocation for the terminal in the process of establishing a session for the terminal. The operation of the address. In this implementation manner, the session establishment response message sent by the session management network element to the terminal does not include the address information allocated by the session management network element. The indication information mentioned above may include, for example, an indication information of an IP allocation via DHCP (PCO) of the dynamic host configuration protocol, and/or identification information of an Ethernet type of the session.

In a possible implementation manner, if the session establishment request message does not include the indication information for instructing the terminal to obtain an IP address from the service network, the session management network element needs to allocate the first terminal to the terminal in the process of establishing a session for the terminal. Address (that is, the IP address of the terminal in the access network). Then, the session management network element may send the first address information in the session establishment response message to the terminal, to indicate, by using the session establishment response message, that the session management network element has established a session for the terminal, and indicates the first address allocated for the terminal. information.

After receiving the session establishment response message, the terminal may start executing the process of accessing the service network part after establishing the session, so as to access the service network by using the session. Specifically, the terminal may send an initial access message to the access network to request access to the service network. The initial access message does not include the verification information of the terminal in the service network. In a possible implementation manner, the terminal may immediately send an initial access message to the serving network after establishing the session. The terminal may also send an initial access message to the service network when receiving the data of the service network (for example, an IGMP message) sent by the client after the session is established.

After the terminal can send the initial access message to the access network, the user plane network element can obtain an access message carrying the authentication information of the terminal in the service network, and send the access message to the service network. It can be understood that the foregoing access message and the initial access message sent by the terminal may be determined according to a specific service network. For example, the foregoing access message and the initial access message may be DHCPv4 messages, for example, the DHCP discovery (recover) message or the DHCP request (request) message shown in FIG. 2, for example. The foregoing access message and the initial access message may also be DHCPv6 messages, for example, a DHCP Solicit message or a DHCP Request message. In the embodiment of the present application, one difference between the access message and the initial access message is that the access message has more verification information of the terminal in the service network than the initial access message.

The following describes and describes how the user plane NE obtains the above access message. FIG. 5 is a flowchart of another method for accessing a service network according to an embodiment of the present disclosure. As shown in FIG. 5, the method includes:

S301: The user plane network element obtains an access message, where the access message is used for the terminal to access the service network, and the access message includes: the terminal verification information in the service network.

S302. The user plane network element sends an access message to the serving network.

In a possible implementation manner, the session management network element may send the obtained verification information of the terminal in the service network to the user plane network element in the process of establishing a session for the terminal. In this way, after receiving the initial access message sent by the terminal, the user plane network element can obtain the access message carrying the verification information of the terminal in the service network according to the initial access message and the verification information of the terminal in the service network. . For example, the user plane network element may add the authentication information of the terminal in the service network to the option of the initial serving network access message to obtain an access message.

Taking the IPTV network as an example, if the authentication information of the terminal in the service network is the line ID of the terminal, the user plane network element can add the line ID of the terminal to the sub-option option 82 of the DHCP message. If the authentication information of the terminal in the service network is the MAC address of the terminal, the user plane network element may add the MAC address of the terminal to the sub-option option 61 of the DHCP message. If the authentication information of the terminal in the service network is the type information of the terminal, the user plane network element may add the type information of the terminal to the sub-option option 60 of the DHCP message. If the verification information of the terminal in the service network is the level information of the terminal, the user plane network element may add the level information of the terminal to the sub-option option 77 of the DHCP message.

A possible implementation manner, after receiving the initial access message sent by the terminal, the session management network element may be based on the initial access message, and the terminal acquired in the process of establishing a session for the terminal is in the service network. The verification information acquires an access message carrying the authentication information of the terminal in the service network. Then, the session management network element may send the access message to the user plane network element, so that the user plane network element obtains the access message. The session management network element obtains the access message according to the initial access message and the verification information of the terminal in the service network. For the foregoing, the user plane network element according to the initial access message and the terminal verification information in the service network, Obtain the description of the access message, which will not be described in detail.

After sending the access message to the serving network, the user plane network element can obtain the feedback message of the service network to the access message. Then, the user plane network element can send the feedback message to the terminal to assist the terminal to access the service network. The feedback message mentioned here may be specifically determined according to the foregoing access message. Taking the service network as an example for the IPTV network, if the access message is a DHCP discovery message of the DHCPv4 message, the feedback message may provide a message for the DHCP of the DHCPv4 message. If the access message is a DHCP request message of the DHCPv4 message, the feedback message may be a DHCP acknowledgement (Ack) message of the DHCPv4 message. If the access message is a DHCP Solicit message of the DHCPv6 message, the feedback message may be a DHCP advertisement message of the DHCPv6 message. If the access message is a DHCP request message of the DHCPv6 message, the feedback message may be a DHCP reply message of the DHCPv6 message.

The user plane network element sends the feedback message to the terminal, which may include the following two methods, specifically:

The first mode is that the user plane network element can send the feedback message to the terminal based on the second identifier information of the terminal carried in the feedback message. FIG. 6 is a flowchart of still another method for accessing a service network according to an embodiment of the present application. As shown in FIG. 6, the method includes:

S401. The user plane network element obtains a feedback message of the service network to the access message, where the feedback message includes the second identifier information of the terminal.

S402. The user plane network element sends a feedback message to the terminal according to the second identifier information of the terminal.

In this embodiment, the user plane network element is provided with a mapping relationship between the second identifier information of the terminal and the session information of the terminal. The second identification information of the terminal mentioned herein may be, for example, a Line ID of the terminal, a Xid of the terminal, or the like. The session information of the terminal mentioned herein may be one of the following: the identification information of the session of the terminal, the MAC address of the terminal, the address information of the access network device, the identification information of the access network device, and the tunnel endpoint identifier of the terminal (tunnel) Endpoint identifier (TEID), core network tunnel information. Through the mapping relationship, the user plane network element can determine which session is used to transmit the feedback message.

Therefore, after the user plane network element receives the feedback message of the service network to the access message, the mapping relationship between the second identifier information of the terminal included in the feedback message and the second identifier information of the terminal and the session information of the terminal may be used. , determine the session information of the terminal. Then, the user plane network element can send a feedback message to the terminal through the session corresponding to the session information of the terminal. It should be noted that, because the second identifier information of the terminal is used to enable the user plane network element to determine the session for transmitting the feedback message, the user plane network element may carry the feedback message before sending the feedback message to the terminal. The second identification information of the terminal is deleted. At this time, the feedback message sent by the user plane network element to the terminal is different from the feedback message obtained by the user plane network element. Certainly, the user plane network element may not perform the operation of deleting the second identifier information of the terminal, and may be specifically determined according to the setting of the communication system.

This embodiment does not limit how to set the mapping relationship between the second identifier information of the terminal and the session information of the terminal in the user plane network element. A possible implementation manner, the session management network element may acquire the second identifier information of the terminal and the session information of the terminal, and establish a mapping relationship between the second identifier information of the terminal and the session information of the terminal according to the obtained two pieces of information. And sending the mapping relationship to the user plane network element. After receiving the mapping relationship, the user plane network element can directly store the mapping relationship. Alternatively, the session management network element may send the acquired second identification information of the terminal and the session information of the terminal to the user plane network element. After receiving the two pieces of information, the user plane network element may establish a mapping relationship between the second identifier information of the terminal and the session information of the terminal. Alternatively, the session management network element may obtain the session information of the terminal when the session is established for the terminal, and send the session information of the terminal to the user plane network element. The user plane network element may obtain an initial access message that is sent by the terminal and carries the second identifier information of the terminal when the terminal accesses the service network. Then, the user plane network element can establish a mapping relationship between the second identifier information of the terminal and the session information of the terminal.

For example, if the second identifier information of the terminal is the Xid of the terminal, the session management network element may obtain the initial access message that is sent by the terminal and carries the Xid of the terminal, that is, the second identifier information of the terminal, to acquire the terminal. Second identification information. If the second identifier information of the terminal is the line ID of the terminal, the session management network element may be in the process of establishing a session for the terminal, from the data management network element, or the policy control network element, or the local database, or access. The management network element obtains the line ID of the terminal (that is, the second identifier information of the terminal). It can be understood that, when the second identifier information of the terminal and the verification information of the terminal in the service network are both the line ID of the terminal, the session management network element acquires the second identifier information of the terminal, and the acquiring terminal is in the service. The authentication information in the network is the same operation.

The second implementation manner is that the user plane network element can send a feedback message to the terminal based on the session information of the terminal carried in the feedback message. FIG. 7 is a flowchart of still another method for accessing a service network according to an embodiment of the present application. As shown in Figure 7, the method includes:

S501. The session management network element sends a feedback message of the service network to the access message to the user plane network element, where the feedback message includes session information of the terminal.

S502: The user plane network element sends a feedback message to the terminal according to the session corresponding to the session information of the terminal.

In this embodiment, the mapping relationship between the second identification information of the terminal and the session information of the terminal is set in the session management network element. Therefore, after receiving the feedback message of the service network to the access message, the session management network element may determine the session of the terminal according to the second identification information of the terminal and the mapping relationship between the second identification information of the terminal and the session information of the terminal. information. Then, the session management network element can carry the session information in the feedback message and send it to the user plane network element. In this way, after receiving the feedback message, the user plane network element can directly determine the session that can transmit the feedback message through the session information of the terminal, and send the feedback message to the terminal through the session. For the description of how to configure the mapping between the second identifier information of the terminal and the session information of the terminal, refer to the description of the foregoing embodiment, and details are not described herein.

It should be noted that, because the second identifier information of the terminal is used to enable the session management network element to determine the session for transmitting the feedback message, the session management network element may send a feedback message before sending the feedback message to the user plane network element. The second identification information of the carried terminal is deleted. At this time, the feedback message sent by the session management NE to the user plane network element is different from the feedback message obtained by the session management network element. Of course, the foregoing session management network element may not perform the operation of deleting the second identification information of the terminal, and may be specifically determined according to the setting of the communication system. In addition, the session information of the terminal included in the feedback message is used to enable the user plane network element to determine the session for transmitting the feedback message. Therefore, the user plane network element may send a feedback message before sending the feedback message to the terminal. The session information of the carried terminal is deleted. At this time, the feedback message sent by the user plane network element to the terminal is different from the feedback message received by the user plane network element. Certainly, the user plane network element may not perform the operation of deleting the session information of the terminal, and may be determined according to the setting of the communication system.

As described in the foregoing embodiment, if the session establishment request message sent by the terminal to the session management network element does not include indication information for instructing the terminal to obtain an IP address from the service network, the session management network element is in the process of establishing a session for the terminal. The terminal is also assigned a first address (ie, the IP address of the terminal in the access network), and the user is notified of the first address information allocated by the network element session management network element for the terminal. At the same time, in the process of the terminal accessing the service network, the service network also allocates a second address (ie, the IP address of the terminal in the service network) to the terminal, and carries the second address information in the feedback message to notify the terminal. Therefore, when the terminal sends any uplink message to the service network after acquiring the first address information and the second address information, the uplink message includes the first address information and the second address information.

For example, if the terminal acquires the first address and the second address, the uplink user plane data sent by the terminal may include the first address information and the second address information. Correspondingly, the uplink user plane data acquired by the user plane network element also includes the first address information and the second address information. Since the first address information is invalid address information for the service network, in order to ensure that the service network can accurately receive the uplink user plane data, the user plane network element may delete the uplink before sending the uplink user plane data to the service network. The first address information in the user plane data (ie, deleting the IP address of the terminal in the access network). Then, the user plane network element may send the uplink user plane data after deleting the first address information to the service network.

Correspondingly, when the service network sends the second user address to the terminal, the downlink user plane data includes the second address information. For example, if the service network has assigned a second address to the terminal, the subsequent downlink user plane data will include the second address information. The downlink user plane data obtained by the user plane network element also includes the second address information. Since the second address information is invalid address information for the access network, in order to ensure that the downlink user plane data can be accurately sent to the terminal through the access network, the user plane network element sends the downlink user to the terminal through the access network. Before the face data, the first address information can be added to the downlink user plane data. Then, the user plane network element can use the first address information in the downlink user plane data to send the downlink user plane data to the terminal through the access network. At this time, the downlink user plane data includes: first address information and second address information. That is to say, the downlink user plane data sent by the service network sent by the user plane network element received by the terminal may include the first address information and the second address information. After receiving the downlink user plane data, the terminal may delete the first address information of the downlink user plane data. In this way, even if both the access network and the service network assign addresses to the terminals, the terminals can still access the service network through the access network. Under the premise of not modifying the existing access network to establish the session flow of the terminal, the terminal can access the service network through the access network, thereby improving the user experience.

In this example, the terminal is the RG, the access network is the wireless network, the service network is the IPTV network, the session management network element is the SMF network element, the user plane network element is the UPF network element, and the policy control network element is the PCF network element, and the data. The management network element is the UDM network element, the access management network element is the AMF network element, the authentication information of the terminal in the service network, and the second identification information of the terminal is the Line ID of the RG, and the session information of the terminal is the identification information of the session of the RG. The service network management system network element is the BOSS network element on the IPTV network side, the access network management system network element is the NMS network element on the wireless network side, the subscription request message is the IPTV service subscription request message, and the subscription response message is the IPTV service subscription response. Message.

For example, the RG's line ID is stored in the RG's subscription information. The following describes the process of adding the line ID of the RG to the RG's subscription information when the user subscribes to the IPTV service.

S606a. The SMS network element sends an IPTV service subscription notification response message to the BOSS network element.

The IPTV service subscription notification response message is used to notify the BOSS network element that the SMS network element has added the Line ID of the RG to the information of the RG.

It can be understood that the IPTV service subscription notification message and the IPTV service subscription notification response message mentioned above are only an indication and do not constitute a limitation of the message. In a specific implementation, the foregoing IPTV service subscription notification message may be replaced by any other message used to notify the network element to add the Line ID of the RG to the information of the RG. The IPTV service subscription notification response message may be notified by any other notification. The line ID of the RG is added to the message in the information of the RG instead, which is not limited.

The second mode: the BOSS network element on the IPTV network side triggers the operation of generating the verification information of the terminal in the service network by the NMS network element on the wireless network side. FIG. 8B is a flowchart of still another method for accessing a service network according to an embodiment of the present application. As described in FIG. 8B, the method includes:

The S601b and the BOSS network element receive the IPTV service subscription request message.

S602b: The BOSS network element sends an IPTV service subscription request message to the NMS network element.

The IPTV service subscription request message is used to notify the NMS network element that the RG has subscribed to the service of the IPTV network. The IPTV service subscription request message includes: a first identifier of the RG.

The IPTV service subscription notification message is used to notify the SMS network element to add the Line ID of the RG to the information of the RG.

S609b. The SMS network element sends an IPTV service subscription notification response message to the BOSS network element.

2. After the RG completes registration in the wireless network, a process of establishing a session for data transmission with the service network is established in the wireless network. It can be understood that the process of registering the RG in the wireless network can refer to the prior art, and details are not described herein again. FIG. 9 is a flowchart of still another method for accessing a service network according to an embodiment of the present application. As shown in Figure 9, the method includes:

S701. The RG sends a PDU session establishment request message to the AMF network element.

The PDU Session Establishment Request message is used to request to establish a session for the RG. The protocol data unit (PDU) session establishment request message includes: first identification information of the RG (eg, ID of the RG, IMSI of the RG, GPSI of the RG), DNN (in the example, the DNN is the IPTV), The indication information used to instruct the RG to obtain an IP address from the IPTV network. The DNN is used to indicate that the PDU session is used to transmit data of the IPTV service. That is, it is used for data transmission with the IPTV network. The indication information for instructing the RG to acquire an IP address from the IPTV network may be, for example, indication information of the PCO, and/or identification information of an Ethernet type of the session, or the like.

In a possible implementation manner, before the foregoing S701, the method may further include: determining, by the RG, that the PDU session is established. For example, the RG may determine to establish the PDU session upon completion of the registration process of the wireless network. Alternatively, the RG may determine to establish the PDU session when receiving data of the IPTV service sent by the client.

S702. The AMF network element sends a session management context establishment request message to the SMF network element.

The session context setup request message is used to request the SMF network element to establish a context for the session for the RG. The session context setup request message includes: first identifier information of the RG (for example, an ID of the RG, an IMSI of the RG, a GPSI of the RG, a DNN (in the present example, the DNN is an IPTV), and is used to instruct the RG to obtain an IP address from the IPTV network. Instructions.

After receiving the PDU session establishment request message sent by the RG, the AMF network element may select the SMF network element supporting the IPTV service according to the DNN carried in the PDU session establishment request message. Then, the AMF network element can send a session management context request message to the SMF network element supporting the IPTV service.

S703: The SMF network element interacts with the UDM network element to obtain the line identity identification number of the RG.

After receiving the session management context establishment request message sent by the AMF network element, the SMF network element can interact with the UDM network element to obtain the verification information of the RG in the service network, that is, the Line ID of the RG. For example, the SMF network element may send a query request to the UDM network element, where the query request may include: first identification information of the RG. The UDM network element searches the local database for the verification information corresponding to the first identification information of the RG (ie, the Line ID of the RG) according to the first identification information of the RG. Then, the UDM network element may return a query response message to the SMF network element, where the query response message may include: a Line ID of the RG.

It should be noted that the SMF network element can also obtain the indication information that the RG obtains the IP address from the IPTV network according to the session management context establishment request message, and learns that the RG obtains the IP address from the IPTV network. In this scenario, the SMF network element does not assign an IP address to the RG during the establishment of the PDU session for the RG.

S704. The SMF network element sends a session management context setup response message to the AMF network element.

A session management context response message is used to indicate that the SMF network element has completed establishing the PDU session context of the RG.

S705: The SMF network element interacts with the PCF network element to obtain a policy of the IPTV network corresponding to the session.

The SMF network element may select a DNN carried in the request message according to the session context, and select a PCF network element that supports the IPTV service. In a possible implementation, when a plurality of PCF network elements supporting the IPTV service are included in the wireless network, the SMF network element may select a PCF network element with a small load to perform interaction according to the load of the multiple PCF network elements.

Then, the SMF network element can interact with the PCF network element supporting the IPTV service to establish or adjust a session management policy establishment or modification. For example, the SMF network element may send a policy request message to the PCF network element, where the policy request message may include: the first identification information of the RG and the DNN, to notify the PCF network element by the policy request message, and the current PDU session established by the RG Used to transmit IPTV services. After receiving the policy request message, the PCF network element may send the policy control and charging (PCC) rule of the IPTV service corresponding to the RG to the SMF network element. The PCC rule may include a policy of the IPTV service, for example, a QoS policy of the multicast data of the IPTV service.

S706. The SMF network element sends a session establishment request message to the UPF network element.

The session establishment request message is used to request to establish a session context of the UPF network element. The session establishment request message may include: a Line ID of the RG.

The SMF network element can select the DNN carried in the request message according to the session context, and select the UPF network element that supports the IPTV service. In a possible implementation, when a plurality of UPF network elements supporting the IPTV service are included in the wireless network, the SMF network element may select a small-loaded UPF network element to perform interaction according to the load of the multiple UPF network elements.

S707. The UPF network element sends a session establishment response message to the SMF network element.

The session establishment response message is used to notify the SMF network element that the establishment of the session has been completed.

A possible implementation manner, after receiving the session establishment request message, the UPF network element binds the line ID of the RG to the identifier of the PDU session, and establishes a mapping relationship between the line ID of the RG and the identifier of the PDU session (ie, the terminal). The mapping relationship between the second identification information and the connection information of the terminal). The above mapping relationship may also be referred to as N3 tunnel information (Tunnel info) of the RG.

This completes the process of establishing a PDU session for data transmission between the RG and the IPTV network. It will be understood by those skilled in the art that the step of establishing a session shown in FIG. 9 above does not constitute a limitation on the process of establishing a session, and may include more or fewer steps than the illustration, or some steps may be combined, or Different execution order.

3. The process of accessing the IPTV network through the wireless network after the RG establishes a session in the wireless network. In this embodiment, the RG interacts with a DHCP server (server) of the IPTV network through the wireless network to access the IPTV network. The UPF network element of the wireless network is responsible for relaying messages between the RG and the DHCP server. FIG. 10 is a flowchart of still another method for accessing a service network according to an embodiment of the present application. As described in FIG. 10, the method includes:

S801. The RG sends a DHCP discovery message to the UPF network element.

The DHCP Discover message is used to request the RG to access the IPTV network. At this time, the DHCP discovery message does not include the Line ID of the RG. The DHCP discovery message is the initial access message mentioned above.

S802. The UPF network element adds an option 82 sub-option to the DHCP discovery message.

As shown in the example shown in FIG. 9 , in the process of establishing a session by the RG, the SMF network element sends the Line ID of the RG to the UPF network element. Therefore, before the UPF network element can send the DHCP discovery message to the DHCP server, an Option 82 sub-option is added to the DHCP discovery message. The Option 82 sub-option includes the Line ID of the RG.

A possible implementation manner, in some embodiments, the foregoing action of adding an Option 82 sub-option in a DHCP discovery message may be performed by an SMF network element. Then the above step S802 can also be replaced by the following steps:

Step A: The UPF network element sends a DHCP discovery message to the SMF network element.

Step B: The SMF network element adds an Option 82 sub-option to the DHCP discovery message.

Step C: The SMF network element sends a DHCP discovery message with the Option 82 sub-option to the UPF network element.

S803. The UPF network element sends a DHCP discovery message that adds an option 82 sub-option to the DHCP server.

At this time, the DHCP discovery message is the above-mentioned access message.

S804. The DHCP server interacts with an authentication server of the IPTV network to authenticate the RG by using a line identity identifier of the RG.

For example, the DHCP server may send an authentication request message to the authentication server, where the authentication message includes: a Line ID of the RG. After receiving the authentication request message, the authentication server may query the local database according to the Line ID of the RG carried in the authentication request message. When the Line ID of the RG exists in the local database, it indicates that the RG can use the service of the IPTV network, that is, the RG authentication. In this scenario, the authentication server can send an authentication pass message to the DHCP server. The authentication pass message is used to indicate that the RG authentication is passed. When the RG authentication is passed, the DHCP server may further perform the subsequent step S805.

If the RG authentication fails, the authentication server may send an authentication failure message to the DHCP server. The authentication failure message is used to indicate that the RG authentication fails. When the RG authentication fails, the DHCP server may send a DHCP message to the RG indicating that the RG authentication failed. After receiving the DHCP message, the RG can re-initiate the access procedure. That is, step S801 is re-executed. This flow is not shown in FIG.

S805. The DHCP server sends a DHCP offer message to the UPF network element.

The DHCP providing message is used to notify the RG of the authentication and pass the IP address assigned by the DHCP server to the RG. That is, the IP address of the RG in the IPTV network. At this time, the DHCP providing message is the above-mentioned feedback message. The DHCP providing message includes an IP address assigned to the RG and a sub-option Option 82 (including the Line ID of the RG).

S806. The UPF network element determines the identifier of the session of the RG according to the line identity identification number of the RG carried in the DHCP-provided message.

Because the destination IP address of the DHCP message sent by the DHCP server is not the IP address of the RG, the UPF network element cannot determine which session to use according to the destination IP address of the DHCP message, and transmits the DHCP provision message to the RG. Therefore, if the UPF network element establishes a mapping relationship between the line ID of the RG and the identifier of the PDU session in the process of establishing the session by the RG (ie, step S607), the UPF network element may determine according to the Line ID of the RG in the DHCP providing message. ID of the RG PDU session.

A possible implementation manner, in some embodiments, if the SMF network element is configured with a mapping relationship between the line ID of the RG and the identifier of the PDU session, the action of determining the identifier of the session of the RG may be performed by the SMF network element. Then, the above step S805 can also be replaced by the following steps: the DHCP server sends a DHCP offer message to the SMF network element.

The above step S806 can also be replaced by the following steps:

Step D: The SMF network element determines the identity of the session of the RG according to the Line ID of the RG carried in the DHCP-provided message.

Step E: The SMF network element adds the identifier of the RG session to the DHCP offer message.

Step F: The SMF network element sends a DHCP offer message to the UPF network element to identify the identity of the RG session.

S807. The UPF network element sends a DHCP offer message to the RG.

The DHCP providing message includes: an IP address allocated for the RG.

After obtaining the identifier of the RG PDU session, the UPF network element may send a DHCP providing message to the RG through the PDU session corresponding to the identifier. At this time, the DHCP offer message sent to the RG may not include the sub-option Option 82.

S808. The RG sends a DHCP request message to the UPF.

At this time, the DHCP request message does not include the Line ID of the RG. The DHCP request message is the initial access message mentioned above. The DHCP request message is used to query whether the IP address assigned by the DHCP server is available. This process is used to prevent the DHCP server from assigning the same IP address to the two RGs, which prevents the RG from using the IP address to access the IPTV network.

S809. The UPF network element adds an option 82 sub-option to the DHCP request message.

As a possible implementation, in some embodiments, the foregoing action of adding an Option 82 sub-option in the DHCP request message may be performed by the SMF network element. Then the above step S809 can also be replaced by the following steps:

Step G: The UPF network element sends a DHCP request message to the SMF network element.

Step H: The SMF network element adds an Option 82 sub-option to the DHCP request message.

Step I: The SMF network element sends a DHCP request message with the Option 82 sub-option to the UPF network element.

S810. The UPF network element sends a DHCP request message that adds an option 82 sub-option to the DHCP server.

At this time, the DHCP request message is the above-mentioned access message.

S811. The DHCP server sends a DHCP acknowledgement message to the UPF network element.

The DHCP acknowledgement message is used to notify the RG that the assigned IP address is available. At this time, the DHCP confirmation message is the above-mentioned feedback message. The DHCP acknowledgement message includes an IP address assigned to the RG and a sub-option Option 82 (including the Line ID of the RG).

S812: The UPF network element determines the identifier of the session of the RG according to the line identity identification number of the RG carried in the DHCP acknowledgement message.

A possible implementation manner, in some embodiments, if the SMF network element is configured with a mapping relationship between the line ID of the RG and the identifier of the PDU session, the action of determining the identifier of the session of the RG may be performed by the SMF network element. Then, the above step S811 can also be replaced by the following steps: the DHCP server sends a DHCP confirmation message to the SMF network element.

The above step S812 can also be replaced by the following steps:

Step J: The SMF network element determines the identifier of the session of the RG according to the Line ID of the RG carried in the DHCP acknowledgement message.

Step K: The SMF network element adds the identifier of the session of the RG in the DHCP acknowledgement message.

Step L: The SMF network element sends a DHCP confirmation message indicating the identity of the RG-added session to the UPF network element.

S813. The UPF network element sends a DHCP notification message to the RG.

The DHCP notification message includes an IP address assigned to the RG.

S814. The SMF network element performs a session management policy adjustment process.

After obtaining the IP address assigned by the DHCP server to the RG, the SMF network element can initiate a session management policy modification process to the PCF network element to notify the PCF network element RG in the IPTV. The IP address in the network and the updated PCC rules (such as QoS rules) are obtained from the PCF network element. The SMF network element can then update the QoS rules obtained from the PCF network element to the UPF network element and the RG.

This completes the process of RG accessing the IPTV network through the wireless network. Then, the RG can configure the address of the RG in the IPTV network to the STB, and perform network address translation (NAT) to implement conversion of the intranet address and the external network address. Then, the STB connected to the RG can acquire the data provided by the IPTV network through the RG and provide it to the user. It can be understood by those skilled in the art that the step of accessing the IPTV network shown in FIG. 10 does not constitute a limitation on the process of accessing the IPTV network, and may include more or less steps than the illustration, or a combination of Some steps, or different execution orders.

It should be noted that the session establishment request message sent by the RG in FIG. 9 and FIG. 10 includes an indication information for instructing the RG to obtain an IP address from the IPTV network as an example, and how the RG accesses the IPTV network through the wireless network. And introduction. That is to say, in the above process of establishing a session for the RG, the SMF network element does not allocate an IP address in the wireless network to the RG.

It should be noted that, if the session establishment request message sent by the RG does not include: indication information for instructing the RG to obtain an IP address from the IPTV network, the SMF network element needs to be allocated for the RG in the process of establishing a session for the RG. IP address in the wireless network. Taking the 5G communication system as an example, the SMF network element assigning an IP address in the wireless network to the RG may be referred to as 5GC IP. The SMF network element allocates an IP address in the wireless network to the RG. For example, the operation of the SMF network element to allocate an IP address in the wireless network to the terminal is not described herein.

In this scenario, for each uplink message between the RG and the UPF network element (for example, a DHCP discovery message, a DHCP request message), since the messages need to be transmitted through the 5GC IP (that is, the uplink message is overlaid on the 5GC IP), The RG will carry 5GC IP in these upstream messages. Correspondingly, after receiving the uplink message, the UPF network element deletes the 5GC IP carried in the upper message (that is, deletes the head of the 5GC IP layer), and sends the uplink message that deletes the 5GC IP to the DHCP server of the IPTV network. . For example, the UPF network element can determine the 5GC IP carried in the uplink message according to the mapping relationship between the 5GC IP and the line ID of the RG, and delete the 5GC IP from the uplink message. Alternatively, the 5GC IP is located in a preset field of the uplink message, and after receiving the uplink message, the UPF network element may directly delete the field to delete the 5GC IP. Correspondingly, for each downlink message between the RG and the UPF network element (for example, a DHCP providing message, a DHCP notification message), since the message needs to be transmitted through the 5GC IP (that is, the downlink message is overlaid on the 5GC IP), the UPF network The meta-communication carries 5GC IP in these downstream messages. Correspondingly, after receiving the downlink messages, the RG deletes the 5GC IP carried in the subsequent messages (that is, deletes the header of the 5GC IP layer). For example, the UPF network element can determine the 5GC IP of the RG according to the mapping relationship between the 5GC IP and the line ID of the RG, and add the 5GC IP to the downlink message. In this way, even if both the wireless network and the IPTV network assign an IP address to the RG, the RG can still access the IPTV network through the wireless network and acquire data of the IPTV network. Under the premise of not modifying the existing wireless network to establish a session flow, the RG can access the IPTV network through the wireless network, thereby improving the user experience.

The method for accessing the service network provided by the embodiment of the present application enables the RG to access the IPTV network through the wireless network, thereby expanding the usage scenario of the IPTV network.

A possible implementation manner, the service network involved in the embodiment of the present application may provide at least one multicast service. The user can subscribe the terminal to the rights of one or more multicast services in at least one multicast service, such as: fully allowed, not allowed, preview allowed, and the like. Therefore, the service network management system network element on the service network side can generate the multicast service authority information of the terminal when the user subscribes to the multicast service of the service network. The multicast service authority information includes the right of the terminal to correspond to at least one multicast service provided by the service network. It can be understood that the terminal mentioned here may be an STB or a terminal integrated with an STB function and an RG function.

After the multicast service authority information of the terminal is generated, the network element of the service network management system may send the multicast service authority information of the terminal to the network element for storing information of the terminal in the service network for unified storage. For example, the service network management system network element is a BOSS network element, and other network elements for storing information of the terminal are SMS network elements.

Illustratively, the service network can provide three multicast services as an example, namely, multicast service 1, multicast service 2, and multicast service 3. When the user subscribes to the service access network, the rights of the multicast service 1 are completely allowed, the rights of the multicast service 2 are not allowed, and the permission of the multicast service 3 is allowed to be previewed. The multicast service authority information of the terminal may be as shown in Table 1 below:

Table 1

终端terminal	组播业务1Multicast service 1	组播业务2Multicast service 2	组播业务3Multicast service 3
终端的标识Terminal identification	完全允许Fully allowed	不允许Not allowed	允许预览Allow preview

It can be understood that the multicast service authority shown in Table 1 above is only an indication and does not constitute a limitation on the multicast service authority. In specific implementation, the rights of the multicast service may be specifically determined according to the rights set by the service network.

The identifier of the terminal may be any one of the following: an ID of the terminal, an IMSI of the terminal, a GPSI of the terminal, an MSISDN of the terminal, a Line ID of the terminal, a MAC address of the terminal, type information of the terminal, and a terminal. The level information, the user name information used when the terminal accesses the service network, and the like.

In this embodiment, in a scenario in which the terminal accesses the service network through the access network shown in FIG. 3, other network elements in the service network for storing information of the terminal may send the multicast service authority information of the terminal to the terminal. The network element on the network side can access the network element of the terminal to store the multicast service authority information of the terminal as the terminal information. The network element on the access network side may be, for example, a network management network element (for example, an NMS network element), a data management network element (for example, a UDM network element), or a policy control network element (for example, a PCF network element), or Network open network element. Exemplarily, the network open network element may be, for example, a network exposure function (NEF) network element (not shown in FIG. 3).

Taking the network element on the access network as the data management network element as an example, after receiving the multicast service authority information of the terminal, the data management network element can search for the locality based on the identification information of the terminal corresponding to the multicast service authority information of the terminal. The subscription information of the terminal stored in the database, and the multicast service authority information of the terminal is added to the subscription information of the terminal. Taking the network element on the access network side as an example, after receiving the multicast service authority information of the terminal, the policy control network element can search for the information stored in the local database based on the identification information of the terminal corresponding to the multicast service authority information of the terminal. The policy information of the terminal is added to the policy information of the terminal.

It can be understood that, when the network element on the access network side is an NMS network element and a NEF network element, the network element on the access network side may not perform the storage operation after receiving the multicast service authority information of the terminal, but The multicast service permission information of the terminal is sent to other network elements on the access network side that need to store the information for storage. The other network elements that need to store the information herein may be, for example, a data management network element (for example, a UDM network element) or a policy control network element (for example, a PCF network element).

After the network element on the access network stores the multicast service authority information of the terminal as the information of the terminal, when the subsequent terminal accesses the service network through the access network, the access network can use the multicast service permission of the terminal. The information controls the multicast service of the terminal. Based on the architecture of the network shown in FIG. 3, the following describes how the access network controls the multicast service of the terminal in some embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

FIG. 10A is a flowchart of still another method for accessing a service network according to an embodiment of the present application. In this embodiment, after the terminal accesses the service network through the access network, the user plane network element (for example, the UPF network element) accessing the network performs the multicast service of the terminal according to the multicast service request message of the terminal. The process of control. The embodiment of the present invention relates to a network element: a session management network element (for example, an SMF network element), a user plane network element (for example, a UPF network element), and a network element that accesses the multicast service authority information of the network side storage terminal (for example: a policy control network element (such as a PCF network element), a data management network element (such as a UDM network element), a network management network element (such as an NMS network element), a data management network element (such as a UDM network element), or a network open network element ( For example, NEF network element)).

As shown in FIG. 10A, the method includes:

S901: The user plane network element obtains a multicast service request message, where the multicast service request message is used by the terminal to obtain data of the first multicast service provided by the service network, where the multicast service request message includes: a first network connection identifier, and a An identifier of the multicast service, where the first network connection identifier is a network connection identifier used by the terminal to access the service network, and the first multicast service is one of at least one multicast service provided by the service network.

S902: The user plane network element determines, according to the first network connection identifier and the identifier of the first multicast service, the right of the terminal corresponding to the first multicast service.

S903. The user plane network element controls, according to the right of the terminal corresponding to the first multicast service, a range of data of the first multicast service that is sent to the terminal.

Specifically, after the terminal accesses the service network through the access network, the user may trigger the terminal to initiate a multicast service request message requesting the first multicast service data. The multicast service request message includes a first network connection identifier and an identifier of the first multicast service. The identifier of the first multicast service mentioned here may be, for example, an ID of the first multicast service or a multicast address of the first multicast service. The first network connection identifier mentioned here may be, for example, address information, a session identifier, and a tunnel endpoint identifier allocated by the service network.

When the terminal is an STB, the address information allocated by the service network mentioned herein may be an IP address allocated by the service network to the RG when the RG corresponding to the STB accesses the service network through the access network. The session identifier mentioned here is the identifier of the session established by the access network for the RG corresponding to the STB. The tunnel endpoint identifier mentioned here is the tunnel endpoint identifier generated when the access network is a session established by the RG corresponding to the STB. When the terminal is a terminal integrated with the STB function and the RG function, the address information allocated by the service network herein may be an IP address allocated by the service network to the terminal when the terminal accesses the service network through the access network. The session identifier mentioned here is an identifier of a session established by the access network for the terminal. The tunnel endpoint identifier mentioned here is the tunnel endpoint identifier generated when the access network is a session established by the terminal.

In the embodiment of the present application, after obtaining the multicast service request message of the terminal, the user plane network element may determine, according to the first network connection identifier and the identifier of the first multicast service, the right of the terminal corresponding to the first multicast service. Then, the user plane network element can control the range of data of the first multicast service that is sent to the terminal according to the right of the terminal corresponding to the first multicast service. For example, the multicast service privilege information of the terminal shown in Table 1 is taken as an example. When the first multicast service is the multicast service 1 in Table 1, the privilege of the terminal corresponding to the first multicast service is completely allowed. In this scenario, when the user plane network element receives the data of the multicast service 1 broadcasted by the service network, it is forwarded to the terminal. When the first multicast service is the multicast service 2 in Table 1, the rights of the terminal corresponding to the first multicast service are not allowed. In this scenario, when the user plane network element receives the data of the multicast service 2 broadcasted by the service network, it is not forwarded to the terminal. When the first multicast service is the multicast service 3 in Table 1, the right of the terminal corresponding to the first multicast service is allowed to be previewed. In this scenario, when the user plane network element receives the preview data of the multicast service 3 broadcasted by the service network, it is forwarded to the terminal, and when it receives the non-preview data of the multicast service 3 broadcasted by the service network, it is not forwarded to the terminal. terminal.

The usage scenario of the network.

The user plane network element determines the right of the terminal to correspond to the first multicast service according to the first network connection identifier and the identifier of the first multicast service, and may include the following two implementation manners:

The first mode: the user plane network element can obtain the correspondence between the second network connection identifier of the terminal and the multicast service authority information. The second network connection identifier mentioned above is a network connection identifier used when the terminal accesses the service network, for example, address information, a session identifier, and a tunnel endpoint identifier allocated by the service network. For a description of the second network connection identifier, refer to the description of the first network connection identifier described above. In this embodiment, the first network connection identifier is the same as the second network connection identifier, or the first network connection identifier corresponds to the second network identifier.

Therefore, the user plane network element can determine the right of the terminal corresponding to the first multicast service according to the first network connection identifier, the identifier of the first multicast service, and the correspondence between the second network connection identifier of the terminal and the multicast service authority information. . For example, when the first network connection identifier and the second network connection identifier are the same, the user plane network element may search for the first network connection identifier and the first in the correspondence between the second network connection identifier of the terminal and the multicast service authority information. The privilege of the first multicast service corresponding to the identifier of the multicast service, and the privilege of the first multicast service is used as the privilege of the terminal corresponding to the first multicast service.

For example, when the first network connection identifier corresponds to the second network connection identifier, the user plane network element may be configured according to the first network connection identifier, the identifier of the first multicast service, the second network connection identifier of the terminal, and the multicast service authority information. Corresponding relationship, and the correspondence between the first network connection identifier and the second network connection identifier, determining the authority of the terminal to the first multicast service. For example, the user plane network element may first search for the second network connection identifier corresponding to the first network connection identifier in the correspondence between the first network connection identifier and the second network connection identifier. Then, the user plane network element may search for the first multicast service corresponding to the identifier of the second network connection identifier and the identifier of the first multicast service from the correspondence between the second network connection identifier of the terminal and the multicast service authority information. The authority is used, and the authority of the first multicast service is used as the authority of the terminal corresponding to the first multicast service.

The embodiment does not limit that the user plane network element can obtain the correspondence between the second network connection identifier of the terminal and the multicast service authority information. In a possible implementation manner, the user plane network element obtains the multicast service authority information of the terminal and the second network connection identifier, and establishes the second network connection identifier of the terminal according to the multicast service authority information of the terminal and the second network connection identifier. Correspondence with multicast service authority information. In a specific implementation, the user plane network element may establish the multicast service authority information of the terminal according to the correspondence between the identifier of the terminal and the multicast service authority information of the terminal, and the correspondence between the identifier of the terminal and the second network connection identifier. The correspondence between the two network connection identifiers.

Continuing with the example shown in Table 1, the user plane network element can associate the terminal with the corresponding relationship between the identifier of the terminal and the multicast service authority information of the terminal, and the correspondence between the identifier of the terminal and the second network connection identifier. The correspondence between the identifier and the multicast service authority information of the terminal is replaced by: the multicast service authority information of the terminal and the second network connection identifier are associated with each other. The mapping between the multicast service authority information of the terminal and the second network connection identifier may be as shown in Table 2 below:

In a specific implementation, the user plane network element can obtain the multicast service authority information by receiving the multicast service authority information of the terminal sent by the session management network element. For example, the session management network element may interact with the network element that stores the multicast service authority information of the terminal on the access network side when the terminal performs the session establishment process on the access network, and obtain the multicast service authority information of the terminal. The network element storing the multicast service authority information of the terminal on the access network side is a policy control network element (for example, a PCF network element), a data management network element (for example, a UDM network element), and a network management network element (for example, an NMS network element).

After obtaining the multicast service permission of the terminal, the session management network element may send the multicast service authority information of the terminal to the user plane network element, so that the user plane network element obtains the multicast service authority information of the terminal.

The user plane network element can obtain the second network connection identifier by using a process in which the terminal accesses the service network. Illustratively, the user plane network element may obtain the second network connection identifier by using the process of the terminal accessing the service network through the access network, or the process of accessing the service network by using the access terminal through the access network. The second network connection identifier is obtained, which is not limited in this embodiment.

The identifier establishes a correspondence between the second network connection identifier of the terminal and the multicast service authority information. After the correspondence between the second network connection identifier of the terminal and the multicast service authority information is established, the correspondence between the second network connection identifier of the terminal and the multicast service authority information is sent to the user plane network element. In this way, the user plane network element can obtain the second network connection identifier and the multicast service authority information of the terminal by receiving the correspondence between the second network connection identifier of the terminal and the multicast service authority information sent by the session management network element.
