For example, the transmission tunnel may be (GPRS tunneling protocol for the user plane, GTP-U); Then, the access gateway can send the modified uplink data packet to the user plane network element of the core network.

Correspondingly, when the access gateway receives the downlink data packet sent by the user plane network element of the core network, the access gateway may decapsulate the downlink data packet (for example, GTP-U decapsulation), and determine and The access network session corresponding to the IP address of the terminal is used to modify or add an access network packet header for the decapsulated downlink data packet, and the MAC address of the terminal is used as the destination MAC address, and the MAC address of the access gateway is used as the MAC address of the access gateway. The source MAC address is sent to the terminal after the access gateway adds the downlink data packet of the access network header.

In the second type, when the access network session information includes the indication information of the IP address acquisition mode, the access gateway acquires the IP address of the terminal according to the IP address acquisition mode, and performs session mapping according to the IP address of the terminal.

Specifically, the access gateway may monitor the IP address of the terminal according to the IP address acquisition manner indicated by the indication information, and then map the access network session and the mobile network session corresponding to the terminal according to the first manner. For example, when the IP address is obtained through DHCP, the access gateway can listen to the DHCP packet, obtain the IP address of the terminal from the DHCP packet, and then access the terminal according to the first method. Network sessions and mobile network sessions are mapped.

In the third type, when the access network session information includes the user packet information from the terminal, the access gateway maps the access network session corresponding to the terminal in its corresponding mobile network session by using the user message information.

Specifically, the access gateway may send the user packet information to the access resource management network element (ACRF). When the access resource management network element receives the user packet information, the access resource management network element may access the information. The gateway sends the mapping information, where the mapping information includes a mapping rule, and the mapping information may be obtained by the access resource management network element according to the user message information from the terminal. Then, when the access gateway receives the mapping information, the access gateway may map the access network session corresponding to the terminal in its corresponding mobile network session according to the mapping rule included in the mapping information.

Optionally, the access resource management network element may further generate a mapping relationship between the access network session and the mobile network session, and send the mapping relationship together with the mapping rule to the access point (AN) and the access gateway (AGF). The mapping rule and mapping relationship can be saved locally by the access point and the access gateway. When receiving the uplink data packet from the terminal, the access gateway may forward the uplink data packet from the terminal to the corresponding mobile network session according to the mapping relationship and the mapping rule; correspondingly, when the access gateway receives the received data packet, The downlink data packet from the user plane network element can be forwarded to the corresponding access network session according to the mapping relationship and the mapping rule.

For example, as shown in FIG. 3, it is assumed that the VLAN ID of the terminal reported in the user packet information is VLAN 1 (or the VLAN ID obtained from the AAA server is VLAN 1), and the number of VLAN tags can be 0 (ie, untag). , 1 (ie c-tag), or 2 (ie s-tag+c-tag). The VLAN ID of the uplink data packet sent by the access gateway to the access point is VLAN 2, and the VLAN 2 is the VLAN identifier of the VLAN tag in the uplink data packet sent by the access point (AN). The number of tags may be 1 (ie, c-tag'), or 2 (ie, s-tag'+c-tag'). The mapping rule corresponding to the access gateway is that the uplink data packet of VLAN 2 corresponds to the mobile. Network session PDU1, and replace VLAN 2 with VLAN1 when forwarding upstream data packets to the mobile network. Specifically, for the uplink data packet, the access gateway may query the mapping rule according to the VLAN 2, determine the corresponding mobile network session, and replace the VLAN 2 in the uplink data packet with the VLAN 1, and then replace the uplink. The data message is forwarded to the corresponding mobile network session (eg, PDU1).

Illustratively, the mapping rule of the fixed session and the mobile network session may be as shown in the following Table 1. The number of the VLAN tag or the number of the included VLAN tags in the uplink data packet sent by the terminal in Table 1 is 0. For example, when mapping 1 or 2, mapping the access network session to the mapping rule of the corresponding mobile network session is illustrated.

Table 1

It should be noted that, in the above table 1, when the 1:1 in the session mapping condition indicates that different users of the same service on the access network session side use different VLAN information (VLAN identification) for identification; N: 1 indicates the access network. Different users in the same service on the session side use the same VLAN information (VLAN ID) for identification. In this case, only VLAN information can be used to distinguish different sessions during session mapping. Therefore, mapping can be performed through VLAN information + MAC. MAC refers to the MAC address of the terminal.

In addition, the mapping rule for mapping the mobile network session to the access network session may be opposite to the operation of Table 1 above. For example, the VLAN identifier and the session mapping condition are 1:1, and when the AGF receives the user plane network element, When the GTP-U encapsulates the data packet, the AGF policy is: GTP-U decapsulation of the data packet, and the access network session is encapsulated by the VLAN identifier of the access network session; the AN policy is: data packet The VLAN ID of the intermediate access network session is translated into the user's VLAN ID. For details on mapping the mobile network session to the access network session, refer to the information in Table 1 above, which is not described in detail in this embodiment of the present application.

Further, when the access network session information includes the indication information of the IP address acquisition mode, after receiving the first message, the access gateway may enable an address resolution protocol (ARP) proxy function. The DHCP snooping function and/or other functions related to the user's service (for example, packet rate limit, etc.). The access gateway enables the ARP proxy function, which means that when the access gateway receives the ARP information of the address requested by the terminal, the ARP proxy responds to the MAC address of the access gateway. The access gateway is enabled with DHCP snooping. It can be used by the access gateway to start listening for DHCP messages.

Correspondingly, when the access network session information in the first message includes the indication information of the IP address acquisition mode, the access gateway may further send a second message to the access resource management network element after receiving the first message, The second message includes the indication information of the IP address acquisition mode, so that when the access resource management network element receives the second message, the access resource management network element instructs the access point (AN) to enable the corresponding function. Optionally, the second message further includes a MAC address of the terminal, so that the access resource management network element obtains the MAC address of the terminal from the second message.

Further, when the access network session information includes the IP address of the terminal and/or the indication information of the IP address acquisition mode, when the first message further includes the MAC address of the terminal, refer to FIG. 4, before the access gateway performs session mapping. (ie, before executing S203), the method further includes: S203a.

S203a: The access gateway verifies the data packet and/or the ARP request message according to the IP address of the terminal and the MAC address of the terminal.

The data packet may be an uplink data packet sent by the terminal to the access gateway, or may be a downlink data packet, where the data packet is mainly used for verifying the uplink data packet. The uplink data packet may include an IP address of the terminal and a MAC address of the terminal. When the access gateway receives the uplink data packet sent by the terminal, the access gateway may verify the IP address of the terminal included in the first message and the MAC address of the terminal, and the terminal included in the uplink data packet. The IP address is the same as the MAC address of the terminal. If the checksum is passed, the access gateway may send the uplink data packet to the core network; if the inconsistency check fails, the access gateway may discard the uplink data packet.

The ARP request message may be a message sent by the terminal to the access gateway for requesting the MAC address of the access gateway. Similarly, the ARP request message may include the IP address of the terminal and the MAC address of the terminal. When the access gateway receives the ARP request message sent by the terminal, the access gateway may verify the terminal included in the first message. The IP address and the MAC address of the terminal are consistent with the IP address of the terminal included in the ARP request message and the MAC address of the terminal. If the consistency check is passed, the access gateway may respond to the ARP request message, that is, the MAC address of the access gateway is sent to the terminal; if the inconsistency check fails, the access gateway does not respond to the ARP request message.

It should be noted that, when the NAS message sent by the access gateway to the terminal includes the MAC address of the access gateway, the terminal may not send an ARP request message to the access gateway.

Optionally, the access gateway may also send an ARP request message for requesting the MAC address of the terminal to the terminal. When the NAS message sent by the access gateway to the terminal further includes the MAC address of the access gateway, the terminal is Upon receiving the ARP request message, the terminal may discard the ARP request message, that is, the terminal may not respond to the ARP request message.

Further, when the access network session information includes the user packet information from the terminal, the core network device can obtain the user packet information in the following two manners. Referring to FIG. 2, referring to FIG. 5, the method further includes: S200a or S200b.

S200a: The core network device receives a session creation request message sent by the terminal, where the session creation request message includes user message information.

The terminal may send a session creation request message to the core network device through the access gateway, and carry the user message information in the session creation request message, so that the core network device receives the user message information. For example, in the case of the fused network shown in FIG. 1, the terminal may send a PDU session creation request to the AGF, where the PDU session creation request carries user message information, and the AGF sends the PDU session creation request to the SMF when receiving the PDU session creation request. The PDU session request information, the SMF parses the received PDU session request information, and obtains user message information.

S200b: The core network device obtains user packet information from the authentication and authorization accounting server.

The authentication authorization account (AAA) server (server) is a server capable of processing user access requests, providing authentication authorization and account services. The main purpose is to manage user access to the network server and provide access to users with access rights. service. When the core network device needs to obtain user information, the core network device may directly or indirectly send a request to the AAA server; correspondingly, when the AAA server receives the request, the AAA server sends the user packet information to the core through the corresponding path. The network device enables the core network device to obtain user packet information.

For example, taking the converged network shown in FIG. 1 as an example, the core network device is an SMF. Specifically, the SMF may directly send a request to the AAA server, or indirectly send a request to the AAA server through the UPF; when the AAA server receives the request directly sent by the SMF, the AAA server may directly send the user message information to the SMF, and when the AAA server receives the SMF, When the request is sent indirectly, the AAA server can send the user message information to the SMF through the UPF, so that the SMF obtains the user message information.

For the sake of understanding, the following uses the converged network shown in FIG. 1 as an example. The first message sent by the core network device to the access network includes the IP address of the terminal, the indication information of the IP address acquisition mode, and the user packet information. For example, the core network device is an SMF, the access gateway is an AGF, the terminal is an RG, the first message is an N2 session creation request, and the access network session information is fixed network session information.

Example 1: The first message includes the IP address of the terminal. Referring to FIG. 6, the method may include the following steps.

S601: The RG sends a PDU session creation request. Optionally, the PDU session creation request includes a MAC address used by the terminal.

S602: The AGF sends a PDU session creation request to the SMF.

Optionally, the PDU session creation request includes a MAC address used by the terminal.

S603: Perform an existing PDU session creation process.

S604: The SMF sends an N2 session creation request to the AGF, where the request includes an IP address of the terminal. Optionally, the MAC address used by the terminal is also included. Further, the request carries the NAS message that is delivered to the RG. Optionally, the NAS message includes the MAC address used by the AGF. The MAC address of the AGF can be obtained through configuration, or sent by the AGF to the core network in other messages. Control surface).

S605: The AGF saves the IP address of the terminal.

Optionally, the MAC address used by the terminal is saved (executed in case S604 sends the MAC address of the terminal). Further, in the case that the MAC address used by the terminal is saved, the AGF may subsequently discard the ARP request message from the terminal in the session or check the ARP request message sent by the terminal.

S606: Create a fixed network side session.

The mapping information of the fixed network session and the PDU session on the AGF may be mapped to the PDU session by using the IP address of the terminal or by using user message information.

S607: The AGF sends a session creation complete message to the RG.

Optionally, the session creation complete message includes the MAC address of the AGF.

S608: The RG saves the MAC address of the AGF (executed in the case where the MAC address of the AGF is sent in S607). In the case that the RG saves the MAC address of the AGF, the RG can use the MAC address of the AGF as the destination MAC address of the uplink data packet, and can obtain the MAC address of the AGF without using the ARP request message.

S609: Verify the uplink and downlink data.

Specifically, the AN and/or the AGF can check whether the IP address of the terminal in the uplink and downlink data packet is consistent with the IP address allocated to the terminal.

S610-S611: When receiving the downlink data packet, the AGF de-packs the GTP-U and adds the Ethernet header to the packet. The MAC address of the terminal saved in S605 is used as the destination MAC address of the packet, and the source MAC address uses the AGF. The MAC address, so that the access gateway can obtain the MAC address of the RG without using an ARP request message, thereby reducing the signaling interaction between the AGF and the RG.

Example 2: The first message includes indication information of an IP address acquisition mode. Referring to FIG. 7, the method may include:

S701-S703: Same as S601-S603 in the first example.

S704: The SMF sends an N2 session creation request to the AGF.

The request includes the indication information, and the manner in which the terminal obtains the IP address may be obtained by using DHCP, DHCPv6, a stateless address allocation protocol, or other protocols. Optionally, the MAC address of the terminal is also included in the request.

S705: The AGF enables the ARP proxy function.

The AGF can not only enable the ARP proxy function, but also enable the DHCP snooping function and other functions. The step can also be performed by the S709.

S706: The AGF sends a session creation request to the ACRF, where the indication information is included in the request. Optionally, the MAC address of the terminal is also included in the request.

S707: The ACRF creates a session and obtains mapping information, for example, according to user message information.

S708: The ACRF sends mapping information, such as VLAN information, to the AGF. Optionally, the relevant policy is sent to the AGF, for example, an ARP proxy, a DHCP proxy, and the like.

S709: The AGF enables the ARP proxy function.

The AGF can not only enable the ARP proxy function, but also enable the DHCP snooping function and other functions. The step is executed in S705.

S710: The ACRF sends mapping information and related policies to the AN. S708 and S708 can be in no particular order.

S711: The AGF sends a session creation complete message to the RG.

S712-S713: The RG and the core network complete the DHCP process. In this process, the AGF forwards the user DHCP message to the N3 PDU session, saves the MAC address of the terminal, and listens for the IP address of the user. Further, when the AGF forwards the downlink data packet to the RG, the MAC address of the saved terminal is used as the destination MAC address in the packet header, and the MAC address of the AGF is used as the source MAC address.

S714-S715: The RG obtains the MAC address of the AGF by using the ARP request message as the destination MAC address of the subsequent uplink data packet.

S716-S717: For the downlink data packet, the AGF decapsulates the GTP-U and adds the Ethernet header to the packet.

The AGF uses the MAC address of the terminal saved by S712 (or the MAC address of the terminal obtained through the ARP request message) as the destination MAC address, and the source MAC address can use the MAC address of the AGF.

Example 3: The first message includes user message information. Referring to FIG. 8, the method may include:

S801: The RG sends a session creation request to the SMF through the AGF, where the request includes user packet information, such as a VLAN identifier, or a number of VLAN tags (may be 0, 1, 2, and no specific VLAN tag is specified). Optionally, the request may further include a MAC address used by the terminal, or a MAC-VLAN table (that is, combination information of a MAC address and a VLAN identifier of the terminal).

S802: Perform an existing session creation process.

S803: The SMF sends an instruction to the AGF to complete the session creation.

The instruction includes user message information in S801, that is, user message information from the RG. Specifically, in a case where the MAC address of the terminal is not included in S801, the SMF may acquire the MAC address of the terminal from other network elements in S802, and may send it to the AGF in this step. For example, the SMF is obtained through the AAA server.

S804: The AGF sends a session creation request to the ACRF, where the request includes user message information.

S805-S807: The ACRF creates a mapping rule and mapping relationship corresponding to the fixed network side session, and sends it to the AGF and the AN. For example, the specific mapping rule generation method can be referred to the information in Table 1 above.

S806a: The AGF saves mapping rules for fixed network sessions and mobile network sessions. Optionally, the conversion rule of the VLAN information is saved.

S808: The AGF performs VLAN information conversion on the uplink and downlink data packets and sends the information. Specifically, the uplink and downlink data packet may be an uplink data packet and a downlink data packet. When receiving the uplink data packet on the fixed network side, the AGF forwards the packet to the PDU session corresponding to the session according to the mapping rule. Upon receiving the data message of the PDU session from the UPF, it forwards it to the corresponding fixed network session according to the mapping rule.

Alternatively, in the above-described FIG. 8, the steps of S803 to S808 may be replaced with S809 to S811.

S809: The AGF sends an N4 session creation request to the UPF, where the session creation request includes user packet information, such as a VLAN identifier, or a number of VLAN tags (may be 0, 1, 2, and no specific VLAN tag). . Optionally, the request may further include a MAC address used by the terminal, or a MAC-VLAN table (that is, combination information of a MAC address and a VLAN identifier of the terminal).

S810: The UPF saves mapping rules of the fixed network session and the mobile network session. Optionally, the conversion rule of the VLAN information is saved.

S811: The AGF performs VLAN information conversion on the uplink and downlink data packets and sends the information. Specifically, the uplink and downlink data packet may be an uplink data packet and a downlink data packet. When receiving the uplink data packet on the fixed network side, the AGF forwards the packet to the PDU session corresponding to the session according to the mapping rule. Upon receiving the data message of the PDU session from the UPF, it forwards it to the corresponding fixed network session according to the mapping rule.
