Abstract

The invention discloses a method and device for moving and switching the position of a mobile terminal in a VoIP system. The method and the device disclosed by the invention are applied in a mobile distributed survivable environment. The method comprises the following steps that: the mobile terminal is accessed to a new network node, such that a new network layer identifier and a new service node signalling address are obtained; whether the mobile terminal is in a service or not is judged; re-registration is carried out on the original service node when the mobile terminal is in the service; a network layer identifier in a name and address mapping relationship in the mobile terminal is updated to the new network layer identifier; a mapping relationship of a signalling address and a service address of the mobile terminal and a mapping relationship of a signalling address and a service address of a corresponding communication side are updated on the original service node; and the mobile terminal performs service data communication with a client side at a corresponding communication side by adopting a new service address. According to the invention, a method that a visit mode is combined with an ownership mode is adopted; service communication in motion is realized; and the mobile management effect is realized.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method for realizing mobile switching of a mobile terminal in a VoIP system. Background technique [0002] Session Initiation Protocol (SIP for short) is widely used in VoIP (Voiceover Internet Protocol, VoIP for short) system of VoIP. The application development of wireless network has been widely used in the core network of mobile and telecommunication operators, and there is a trend of application development in other special fields. [0003] In the application of wireless networks, terminal mobility is its basic attribute. The most commonly used mobility management mechanism in the IP technology system is MIP technology, but because MIP technology requires both network nodes and terminal devices, and there is a certain amount of overhead It has not been widely used, so when the IP layer fails to provide effective support for terminal mobility, the mobility manage...
