PURPOSE:To automatize the registration and release of absence transfer by registering and releasing absence transfer by means of the notice of a charging stop and a charging start from a pocket bell. CONSTITUTION:When the pocket bell 2 is taken out from a charger 3, a charging stop detection notice part 20 detects the charging stop and gives a notice to an exchange 1 via a pocket bell master unit 5. When the pocket bell 2 is set in the charger 3, a charging start detection notice part 21 detects the charging start and gives the notice to the exchange 1. When the absence transfer registration part 120 of the exchange 1 receives the notice of the charging stop, it registers the pocket bell 2 to the absence transfer registration part 120. When an absence transfer release part 121 receives the notice of the charging start, it releases the registration of the transfer destination. Thus, the registration and release of absence transfer can automatically be executed. When the power of the pocket bell 2 is turned off and when charging quantity becomes less than prescribed quantity, it is preferable to release the registration of an absence transfer destination. |
