Message transmission method and device

Abstract

The embodiment of the invention discloses a message transmission method and a message transmission device. The method comprises the steps as follows: a standby base station gateway receives user information sent by a maser base station gateway, wherein the user information is used for indicating a corresponding relation between a media access control (MAC) address of a base station and virtual local area network (VLAN) information or virtual extensible local area network (VXLAN) information of the base station; the standby base station gateway receives a response message sent by a server to the base station, wherein the response message comprises the MAC address of the base station; the standby base station gateway determines the VLAN information or the VXLAN information corresponding to the response message according to the user information and the MAC address of the base station in the response message; and the standby base station gateway forwards the response message to the base station according to the VLAN information or the VXLAN information corresponding to the response message. According to the message transmission method provided by the embodiment of the invention, a message transmission success rate can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for transmitting messages. Background technique [0002] In the process of transmission, the message may need to be forwarded by several forwarding devices before reaching the destination device. For example, in the process of blind start of the base station, the base station needs to send a message to the DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) server through the base station gateway. A request message for requesting allocation of an IP (Internet Protocol, Internet Protocol) address, and receiving a response message sent by the DHCP server for allocating the IP address, so as to obtain the IP address allocated by the DHCP server. Currently, a base station is configured with two base station gateway devices, and the two are mutually active and standby. The base station sends a request message and receives a response message thr...

Currently, a base station is configured with two base station gateway devices, and the two are mutually active and standby. The base station sends a request message and receives a response message through the main base station gateway. The request message carries the MAC (Media Access Control, Media Access Control) address of the base station. The main base station gateway generates the mapping relationship between the MAC address of the base station and VLAN (Virtual Local Area Network, virtual local area network) information according to the request message, and when the main base station gateway receives the response message carrying the MAC address of the base station, according to the response message The carried MAC address and the mapping relationship stored locally forward the response message to the base station. Since the primary base station gateway and the backup base station gateway have the same private network gateway IP address, the response message may be transmitted to the backup base station gateway. The request message sent by the base station to the server was not received, so the gateway of the standby base station did not store the mapping relationship between the MAC address of the base station and the VLAN information, and could not forward the response message, but had to discard it, which resulted in the failure of the blind start of the base station
