Estimating the term…
A cellular telephone network comprising an exchange (101) and a voice messaging center (102) connected to the exchange, the exchange being connectable to a plurality of cellular telephones (103), each having an associated voice mailbox (VM1) at the voice messaging center (102), the exchange (101) being operable in the event of failure to connect a caller to a desired telephone (103) to divert the call to the voice messaging center (102) which can record a message from the caller in the associated mailbox (VM1). When such a message has been stored, the VMC transmits a "message waiting" flag for that telephone to the exchange (101). The exchange (101) transmits a "message waiting" signal to the telephone when it registers with a cell of the network, and/or if it initiates an outgoing call.
A communications system for connecting calls from a first user terminal to a desired one of a plurality of second user terminals via a network and operable if the system is unable so as to connect the first user terminal to the desired second user terminal, to store a message from the first user terminal, characterised in that the system includes means for detecting the registration of the second user terminal with the network, where registration is the transition from a state where the second user terminal is unable to make or receive calls to a state where it is able to do so, and means for automatically transmitting a message indication signal to the second user terminal when the second user terminal registers with the network, in the event that such a message has been stored, and
A cellular telephone system comprising an exchange and a voice messaging centre connected to the exchange, the exchange being connectable to a plurality of cellular telephones via a network, said exchange being operable in the event of a failure to connect a caller to a called telephone, to divert the call to the voice messaging centre, and said voice messaging centre being operable to record a message associated with said call, said system comprises means operable when said message has been stored to set a "message waiting" flag for said called telephone, and means for detecting when said called telephone registers with the cellular telephone network such that said network recognizes said called telephone as being associated with the network, whether a "message waiting" flag has been set, and if said flag for said called telephone is detected, means responsive thereto operable to send a "message waiting" signal to said called telephone, wherein registration is the transition from a state where the second user terminal is unable to make or receive calls to a state where it is able to do so.
A cellular telephone network comprising:
A method of operating a communication system, said system including an exchange, a voice messaging centre connected to the exchange and a plurality of user terminals connected to the exchange, said method comprising:
A communications system for connecting calls from a first user terminal to a desired one of a plurality of second user terminals via a network and operable if the system is usable so as to connect the first user terminal to the desired second user terminal, to store a message from the first user terminal, to store a message from the first user terminal, characterised in that the system includes means for detecting the registration of the second user terminal with the network, where registration is the transition from a state where the second user terminal is unable to make or receive calls to a state where it is able to do so, and means for automatically transmitting a message indication signal to the second user terminal when the second user terminal registers with the network, in the event that such a message has been stored,
A method of connecting a call from a first user terminal to a second user terminal via a communication network comprising, connecting the first and second user terminals if the second user is currently registered with the network and is available, and if the second user is currently unregistered or unavailable, storing a message from the first user terminal, and when the second user subsequently registers with the communication network, indicating to the second user terminal that the message is available to be replayed, wherein registration is the transition from a state where the second user terminal is unable to make, maintain or receive a call to a state where it is able to do so.
A communications systems for connecting a first user terminal to a desired one of a plurality of second user terminals via a network and operable if the system is unable so as to connect the first user terminals to the desired second user terminal, to store a message from the first user terminal, said system including means for detecting the registration of the second user terminal with the network, wherein the network in response to said means for detecting recognizes said second user terminal as being currently associated with the network and wherein registration is the transition from a state where the second user terminal is unable to make or receive calls to a state where it is able to do so, and means for automatically transmitting a message indication signal to the second user terminal when the second user terminal registers with the network, in the event that such a message has been stored,
A communications system for connecting a first user terminal to a desired one of a plurality of second user terminals via a network and operable if the system is unable so as to connect the first user terminal to the desired second user terminal, to store a message from the first user terminal, said system including means for detecting the registration of the second user terminal with the network, and means for automatically transmitting a message indication signal to the second user terminal when the second user terminal registers with the network, in the event that such a message has been stored, and
A cellular telephone network comprising:
A method of operating a communication system, said system including an exchange, a voice messaging centre connected to the exchange and a plurality of user terminals connected to the exchange, said method comprising:
A communications system for connecting calls from a first user terminal to a desired one of a plurality of second user terminals via a network and operable if the system is unable so as to connect the first user terminal to the desired second user terminal, to store a message from the first user terminal, characterised in that the system includes means for detecting the registration of the second user terminal with the network, wherein the network in response to said means for detecting recognizes said second user terminal as being currently associated with the network and wherein registration is the transition from a state where the second user terminal is unable to make or receive calls to a state where it is able to do so, and means for automatically transmitting a message indication signal to the second user terminal when the second user terminal registers with the network, in the event that such a message has been stored.
A cellular telephone network comprising an exchange and a voice messaging centre connected to the exchange, the exchange being connectable to a plurality of cellular telephones, said exchange being operable in the event of a failure to connect a caller to a called telephone, to divert the call to the voice messaging centre, and said voice messaging centre being operable to record a message associated with said call, said network comprising means within said voice messaging centre operable, when said message has been stored for said called telephone, to transmit a "message waiting" flag for that telephone to the exchange and said exchange including means operable, when such a flag is received, for calling that telephone when it registers with the cellular telephone network and for sending a "message waiting" signal.
