Abstract

In a multi-channel mobile radio telephone system with multiple base stations covering different geographical areas, mobiles may move freely from area to area and automatically originate and receive calls to and from a landswitched telephone network by direct dialing to and from anywhere in the system by means of a Roving Mobile Call System (RMCS). Mobile subscribers operating out of range of their home base stations (where they are registered for billing purposes) may originate any class of call via any base station in the system and be billed by the home base station by means of intercommunicating base stations in a Roving Mobile Ticketing System (RMTS). Provision is made for tariff sharing as necessary by participating stations. All call signalling and central signalling is performed out-of-band. Call signalling from any base station to mobiles is common to all radio channels transmitted by that station. Mobiles may be in the standby condition on any radio channel regardless of whether it is in use for communications purposes or not. Mobiles are directed to various channels for communications by the terminal equipment.
