Problems solved by technology

[0006] In the above technical solution, since the session management function network element can determine the routing rule based on the forwarding mode of the N6 interface according to the first information, then, in the prior art If the network element with the session management function can already determine whether to use the local forwarding method or the N19 forwarding method according to whether the anchor point UPF of the two sessions is the same, the solution provided by this application can realize the use of local forwarding in a 5G LAN group Any one of the N19 forwarding mode and the forwarding mode based on the N6 interface solves the problem that these three forwarding modes cannot be used in a 5GLAN group in the prior art

Embodiment 1

[0136] Please refer to Figure 5 , is a flow chart of a routing rule configuration method provided in the embodiment of the present application, and the description of the flow chart is as follows:

[0137] S501. The SMF network element acquires a data routing policy of at least one 5GLAN group.

[0138] In this embodiment of the present application, the at least one 5GLAN group is a 5GLAN group managed by the SMF network element. Specifically, when the 5GLAN group is created, the PCF network element can select an SMF network element for managing the communication of the 5GLAN group for each 5GLAN group through the NRF network element or local configuration or the NEF network element instruction. For example, a PCF network element can select a different SMF network element for each 5GLAN group, that is, a SMF network element manages the communication of a 5GLAN group, or a PCF network element can also select the same SMF network element for different Element, that is, one SM...

Embodiment 2

[0199] Please refer to Figure 7 , is a flow chart of a routing rule configuration method provided in the embodiment of the present application, and the description of the flow chart is as follows:

[0200] S701. The PCF network element acquires a data routing policy of at least one 5GLAN group.

[0201] Wherein, the data routing strategy of the 5GLAN group is similar to that in step S501, and will not be repeated here.

[0202] In the embodiment of the present application, the PCF network element may obtain the data routing policy of at least one 5GLAN group through any one of the following methods.

[0203] In the first acquisition method, the data routing policy of at least one 5GLAN group is pre-configured on the PCF network element.

[0204] Specifically, when the AF network element creates a 5GLAN group, it generates a data routing policy for each 5GLAN group. Then, the generated at least one data routing policy is configured on the PCF network element through the NEF...

Abstract

The invention discloses a routing rule configuration method and a communication device, and the method comprises the steps that a session management function network element receives a protocol data unit (PDU) session creation request transmitted by a first terminal, and transmits the information of a data packet through an N6 interface according to the first information for indicating the forwarding of the information of the data packet through the N6 interface; and a routing rule is generated for indicating to send the data packet of the 5G local area network LAN group to which the first terminal belongs to the N6 interface or discard the data packet. The session management function network element can determine the routing rule of the forwarding mode based on the N6 interface accordingto the first information, so that the session management function network element can determine to use the local forwarding mode or the N19 forwarding mode under the condition that the session management function network element can use the local forwarding mode or the N19 forwarding mode; by adopting the scheme provided by the invention, any one of a local forwarding mode, an N19 forwarding modeand an N6 interface-based forwarding mode can be used in a 5G LAN group, and the problem that the three forwarding modes cannot be used in the 5G LAN group in the prior art can be solved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method for configuring routing rules and a communication device. Background technique [0002] The fifth generation mobile communication system local area network (5 th Generation local area network (5G LAN) service is a service provided by the 5G system, which can provide terminals belonging to the same 5G virtual network (5G virtual network group, 5GVN) group with Internet protocol (internet protocol, IP) type or Ethernet (ethernet ) type of private communication. For example, the devices in a factory form a 5G VN group, and the devices belonging to this 5G VN group can send Ethernet data packets or IP data packets to each other. [0003] In 5GLAN, data packets transmitted between devices in a 5G VN group include three forwarding methods, which are divided into local forwarding methods, forwarding methods across user plane function (user plane function,...
