Method and device for realizing network roaming

Abstract

The invention provides a net surfing method for switching subscriber equipments among wireless access points. The method comprises the following steps that: when the physical link between a subscriber equipment and the corresponding wireless access point is disconnected, the connection of the equipment with an upper layer protocol is not interrupted, a timer is started, and the present conversation parameters of the subscriber equipments are stored; the subscriber equipment is connected with a new wireless access point; while in the situation that the physical link between the subscriber equipment and the new wireless access point is established before the timer expires, the subscriber equipment carries out communication by using the stored present conversation parameters. Accordingly, inconvenience to the subscriber caused by the current interruption of service is avoided in the process of the subscriber equipments switching the wireless access points, furthermore, the experience of the subscriber is increased.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network roaming implementation method and device for user equipment to switch between wireless access points. Background technique [0002] Wireless local area network technology is a widely used wireless access technology at present, which uses wireless signals to transmit user information. A common wireless local area network includes a wireless access point (Access Point, referred to as AP) and user equipment (User Equipment, referred to as UE). The UE is connected to the AP through a wireless network, and the AP is connected to a wired network. For networks that require user identity authentication, such as enterprise networks and public networks, it is also necessary to add an Access Controller (AC for short) to authenticate users. Only users who pass the AC authentication can access more A higher level of networking. [0003] At present, enterprise networks and public ...

Problems solved by technology

[0009] It can be seen that in the above process, there will be a short wireless link interruption phenomenon

However, the current PPPoE dial-up software on the UE will automatically prompt the user after detecting that the physical link is disconnected, and automatically or manually re-initiate PPPoE authentication according to the user's choice after the physical link is re-established to renegotiate the link parameters. Since PPPoE authentication takes a certain amount of time to complete, the current business of the user will be interrupted during this period of time, which will bring inconvenience to the user and reduce the user experience.
