線電話機の登録を解除するものである。The roaming information registration / cancellation method disclosed in Japanese Patent Application Laid-Open No. 63-280524 is a plurality of portable radio telephones having a multi-channel access function and a plurality of distributed individual and joint access types. In a system that enables automatic connection of incoming and outgoing calls within a predetermined service area by using a connection device and a wireless line control device connected to and installed in a PBX or an exchange, a unique ID number is given to each system and a home memory is provided. Station system to other I
When the wireless telephone moves to the system of D number and receives the notification signal including the system number which is periodically transmitted from the connection device, automatic location registration is performed to the wireless network control device of the movement destination, When moving from the system to the home memory station or any other system, if the periodical access from the wireless telephone to the destination wireless circuit control device is interrupted for a predetermined period, the wireless telephone is registered as moving to another system. In addition, the wireless network controller of the moving destination activates a timer for each wireless telephone and performs polling in order to confirm the location of the wireless telephone.
When there is no response from the wireless telephone to polling before the timer stops, the wireless telephone registration is canceled assuming that the wireless telephone has moved to another system.

の移動検出に時間がかかる。As described above, in the conventional roaming registration / cancellation method, the wireless telephone moves from the system of the home memory station to the system of another ID number and is periodically transmitted from the connection device. When receiving the notification signal including the system number, perform automatic location registration to the destination wireless network controller, and when moving from this destination system to the home memory station or any other system,
When the periodical access from the wireless telephone to the destination wireless network controller is interrupted for a predetermined period, the wireless telephone is deregistered as if it moved to another system, and
To confirm the location of the wireless telephone, the wireless network controller at the movement destination activates a timer for each wireless telephone and performs polling, and if there is no response from the wireless telephone to the polling before the timer is stopped, another wireless system control device Since the wireless telephone is deregistered as if it moved, it takes time to detect movement of the wireless telephone when the wireless telephone frequently repeats movement.
