Problems solved by technology

[0008] In the above solution, the method of implementing multiple IPs only supports the static configuration of the VLAN or TWAG MAC corresponding to each PDN in TWAG, which requires a lot of configuration work, and requires the mobile terminal to know each PDN, which is not easy to maintain; The method needs to do packet detection in MAG, which is inefficient, and needs to configure the traffic characteristics corresponding to each APN in TWAG in advance, such as a specific quintuple, which requires static configuration, heavy configuration workload, and very difficult to maintain

Abstract

The invention discloses a method for connecting a mobile terminal to multiple PDNs (public data networks) through a fixed network and a related device. The method includes that after the mobile terminal is connected to a first PDN through a gateway of the fixed network and when the mobile terminal needs to be connected to a second PDN through the gateway of the fixed network, the mobile terminal sends a DHCP (dynamic host configuration protocol) request to the gateway of the fixed network, the DHCP request carries an identity of the second PDN, and the first PDN is different from the second PDN; the mobile terminal receives DHCP response information sent by the gateway of the fixed network, and the DHCP response information carries an IP (internet protocol) address of the mobile terminal in the second PDN. By the method and the related device, the mobile terminal can be simultaneously accessed to multiple networks through the fixed network, two-layer processing logic of the mobile terminal does not need to be changed, a large amount of configuration work is not needed, and easiness in maintenance is realized.

Description

technical field [0001] The present application relates to the field of network communication, in particular to a method and a related device for connecting a mobile terminal to multiple PDN networks through a fixed network. Background technique [0002] The integration of fixed network and mobile network can bring users an experience independent of access network. In a 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) network, a user equipment (User Equipment, mobile terminal) can support multiple packet data network (Packet Data Network, PDN) connections on a 3GPP interface, such as using The Internet access point name (Access Point Name, APN) accesses the Internet gateway, uses the session initiation protocol APN to access the IMS network gateway, uses the default APN to access the operator's default gateway, etc. In the prior art, the multi-PDN connection of the mobile terminal may be realized through an interconnection protocol (Internet Prot...
