Abstract

A cellular telephone network comprising an exchange (101) and a voice messaging centre (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 centre (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 centre (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.

Description

~ 1- 2064813 CArr COMPr~TION SYST~

This application reLates to a system for connecting two communications terminals; particularly, but not exclusively, for voice communications; especially by cellular radio voice communication.
It is, of course, annoying when, for some reason, connection to a desired user telecommunications terminal is not possible. This is particularly so with cellular phones, which are often switched off, unattended or out of range, so that resulting call completion rates for land-to-mobile traffic are low (especially at certain times of day).
Messaging services are well known; in particular, in a voice messaging service such as Voicebank (TM), a spoken message is digitally recorded in the mailbox number of the subscri-bed for whom it is intended, which can then retrieve by himself dialling that mailbox. However, since not every user has a mailboJx~ voice messaging is not of itself usually an option ~ a call to a desired user cannot be established~ Moreover, a second, different number must be recalled and dialled by the caller, and there is also no guarantee that the called party will play the message.
When a user knows that he will be unavailable, he could divert his calls to his voice mailbox, but he must remember to do so and, of course, he may not be aware that he ~n unavailable (for example, if he is out of range).
According to the present invention, there is, in one aspect, provided 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 to connect 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, and is arranged automatically to transmit a message -
- 2 - 2064813 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 so to connect the first user terminal to store a message from the first user terminal, characterised in that the system includes means for detecting the availability of the second terminal for communication, and is arranged automatically to transmit a message indication signal to the second user terminal when the second terminal is available in the event that such a message has been stored.
The invention is most useful when the second user terminals are cellular telephones.
In another aspect, there is provided 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, the exchange being operable in the event of a failure to connect a caller to a desired said telephone, to divert the call to the voice messaging centre, and the voice messaging centre being operable to record the call, characterised in that the voice messaging centre is operable, when such a message has been stored for a said telephone, to transmit a "message waiting" flag for that telephone to the exchange and the exchange is operable, when such a flag is received, to call that telephone when that telephone registers with the cellular telephone network and to send a ~message waiting" signal.
Other aspects of the invention are as claimed.
The invention will now be illustrated, by way of example only, with reference to the accompanying drawings in which:-- Figure 1 depicts schematically a system according to the invention.

W O 91/03137 PC~r/GB90/01328
3 20~8~3 - Figure 2 is a flow diagram of the operation of a system according to a first aspect of invention; and - Figure 3 is a flow diagram of the operation of a system according to a second aspect of the invention.

Referring to Figure 1, the system comprises at least one exchange (EMX) 101 and at least one (centrally located) Voice Messaging Centre (VMC) 102; whilst these could of course be co-located, it is equally convenient to provide a direct commllnic~tion link between existing such centres. The ~x~h~n~e (ENX) 101 is connectable to a plurality of subscriber cellular telephones 103 (MOB-l, etc).
Each cellphone 103 on the system would have associated with it a mailbox (VMl) on VMC 102. Mailbox numbers will preferably be identical to the "host" cellphone number.
It will, of course, not be necessary for a user to7 know his mailbox number; the access to the mailbox is controlled between the exchange (EMX) ~ and the Voice Messaging Centre (VMC) 102.
Referring to Figure 2, when a caller (Sl) (104, Fig 1) attempts to call (1) a cellular telephone (MOB-l), he will, if possible (2), be connected (3) as usual. If connection is not possible, the EMX software will check
(4) whether, for that telephone (MOB-l), the automatic messaging option is enabled and, if not, terminate the call (5) as in the prior art. If the option is enabled, the Px~h~nge (EMX) routes the call (6) to the Voice Messaging Centre (VMC), together with the identity of the mailbox (VMl) corresponding to the cellphone (MOB-l) for W O 91/03137 P ~ /GB90/01328 206~8~ - 4 ~

which the message is intended. The caller (Sl) (104, Fig 1) can then choose (7) either to leave a message or not;
this choice might conveniently be offered by a vocal prompt, and a speaker-independent voice recogniser used to recognise a Yes/No response, or the caller may be allowed to register a 'no' response by terminating the call thanging up) within, say, 5 seconds of hearing the prompt. If no message is to be recorded, the call is terminated as before (5). If a message is to be left, it is recorded (8) by the Messaging Centre (VMC) in known fashion, and the call is terminated as before (5).
Although the exhange (ENX) transfers a call to the voice messaging centre (VMC), it does not monitor whether a message has been left or retrieved. It is the task of the VNC to monitor the status of each voice mailbox and inform (9) the EMX of any change, by sending a signal to set or cancel a "message ~-;ting" flag at the Px~h~nge (EMX). It will be the VNC's responsibility to deal with message housekeeping such as automatic deletion after a given period (e.g. several days or weeks), and to signal -~
any status change to the ENX. The VMC will not set the flag each time there is a new message, only when the status changes from no unread messages to one unread message.
To signal between the EMX and VNCr it would be desirable to use some standard data link such as X-25, but it is acceptable to use a telephony sign~ll;ng system such as DTMF to transfer a command digit and mobile identity.
For the latter, it is proposed that the VMC will dial the ENX over direct trunks and that the ENX will know from the digits sent and the trunk used:-a) the mobile identity;

W O 91/03137 PC~r/GB90/01328 ~ ~ 5 ~ ~ 0,6. ~8 1 3 b) whether to set or cancel the "message waiting"flag for that mobile.
It must be possible for these flag setting and flag resetting signals to be routed through transit ENXs if necessary as there will not (with mobile users) always be direct connection between each ENX with a subscriber file and the corresponding YNC.
If no message waiting indication is av~ hle~
cellular telephone users of the invention would be required to regularly access their mailbox to see if any messages have been left. Therefore, in another aspect of the invention, the system automatically indicates to the subscriber when such messages are available.
l. Message waiting indication on call origination In one such embodiment, the indication would be set when the cellphone originates a call if there are unread messages in the mailbox. Nessage retrieval or message time-out (e.g. message deletion after 24 hours) cancels the message waiting indication.
2. Message waiting indication on cellphone registration In a second such embodiment, the message waiting indication would be sent when the cellphone registers. The customer has the option of retrieving messages at this point; the system may allow him to exercise this option by keying, e.g., the SEND key or it may alternatively replay the messages automatically unless he takes some action (e.g. terminates the call).
If a mobile for which a message is waiting registers, then the system will attempt to call the mobile and, if W O 91/03137 ~ P ~ /GB90/01328 ~81~ - 6 - ~

the call is answered, send the indication (preferably, a recorded voiced announ~PmPnt). These calls from the system to the mobile will not be diverted and the action may be limited to one attempt - i.e. not repeated each time the mobile registers.
If the "message waiting" flag is cleared by the VMS
and subsequently set again because a new message has been stored, then the system may try c~ll;ng the mobile after registration.
Referring to Figure 3, one such method of system operation for indicating that a message is waiting will be disclosed.
If the 'message waiting' flag is set (10) and a mobile registers (11), the status of a 'mobile called?~ flag associated with the (or each) message is tested (12). The flag will be set if the mobile has already been notified of the or each message but has not read it so that the 'message waiting' flag is still set.
If the 'mobile called?' flag is set, the EMX monitors whether the mobile attempts to call out (13) within a predetermined time. If the mobile makes no call attempts, the EMX takes no further action (but leaves the status of the flags unaltered).
If the mobile is attempting to call out, then upon its connection to the EMX, the ENX plays (14) the 'message waiting' recorded announcement, and then continues call processing as usual (15).
When the call is completed, and whilst the mobile is still registered, if it attempts to originate further calls the ENX returns to stage 13 and the same process occurs.
Returning to stage 12, if there is a message waiting the presence of which has not been indicated to the mobile W O 91/03137 2 0 6 4 813 PC~r/GB90/0l328 user, the ENX tests (13a) as above whether the mobile is attempting an outgoing call and, if it is, the ENX
procedes as above (14,15) (except that the 'mobile called?' flag is reset after the message).
If it is not, the EMX attempts to place a call to the mobile (16). Should the mobile not answer (17) (due, perhaps, to interference) the ENX takes no further steps (and leaves the status of both flags unchanged). It will be appreciated that at this point other actions, such as a second attempt at calling the mobile, could be undertaken.
If the mobile answers, the EMX plays the 'message waiting' recorded announcement (14a) and resets the Imobile called?' flag. The EMX then tests whether the mobile wishes to hear the message, by waiting a predetermined time (e.g. 5 seconds) and monitoring whether the mobile user has ended the call (18). If he has done so, no further action is taken. If he has not, it is assumed that he wishes to hear the or each message. The EMX therefore connects him to the VMC (19), specifically to his r~llhox and instructs the VMC to replay the or each message.
Although the invention could be implemented on a mandatory basis, it is preferred to provide the invention as a selectable mode of operation of a telecommunication system. Preferably, each user terminal is provided with a way of sign~ ng to the system mode for that terminal is desired (ie to turn on or off the call storing).
The Voice Messaging Centre preferably provides the usual known features offered by voice mail facilities, such as 'message replay', or 'message delete~.
Although the invention has been described as applied to cellular telephones, it is in its broadest sense -W O 91/03137 P ~ /GB9o/01328 2064~13 - 8 - ~

A~pl;C~hle to other classes of subscriber terminal.
It will be understood that, although voice messaging has been described, the invention could equally be applied to store a voiceband data message or even, where a digital network is employed, to store either voice or data messages in the format in which they are transmitted (for example, ASCII characters).
