Abstract: The embodiments of the present disclosure provide a method for data transmission, an offload point device, a user equipment and a system. The method includes: updating, when a first air interface is unavailable, connection context information corresponding to service(s) of a user equipment on the first air interface, wherein the user equipment is connected to a core network through a first access network via the first air interface; sending a first message to the user equipment, wherein the first message carries updating information related to the updated connection context information; and performing data transmission with the user equipment according to the updated connection context information. The above-mentioned technical solution helps preventing all services corresponding to data transmission performed via the first air interface from being interrupted when the first air interface is unavailable, and guaranteeing continuity of the services as much as possible, thereby improving communication experience of a user.
