Abstract

A telephone handset is provided with a user interface which includes a display unit, audio output unit and various user actuable keys. A phone controller implements and responds to instructions from the user interface. Where the instructions from the user interface request the connection of a call, the phone controller connects the handset to a PSTN via one of a plurality of connection means provided. Similarly, in the event of an incoming call connection request received via any one of the connection means, the phone controller enables the connection of the call. The user may choose to accept or reject the connection using the interface. The handling of an incoming or outgoing call is determined by a connection routing engine. The connection routing engine comprises an identification unit, a rules unit, a comparison unit and an enabling unit.

Claims

1. A telephone handset of the type operable to make an outgoing connection to another handset or device and receive an incoming call from another handset or device, the telephone handset comprising:

at least one connection apparatus for connecting incoming or outgoing voice calls to other handsets or devices via a plurality of different networks or other links wherein the handset is further provided with a call handling engine comprising an identification unit, a rules unit, a comparison unit and an enabling unit,

wherein the identification unit is operable to identify the source of an incoming call or the destination of an outgoing call, the rules unit is operable to identify valid options for handling a requested incoming or outgoing call according to predetermined rules, the comparison unit is operable to rank the valid call handling options according to predetermined criteria and the enabling unit is operable to enable the top ranked handling option,

wherein the criteria for ranking the handling options include at least one of;

identified source;

identified destination;

cost, quality, reliability, availability, bandwidth of connection;

expected length of call;

time of call request;

expected duration of call; and

estimated power consumption; and

further wherein there are a number of different ranking criteria settings stored as different operating modes.

2. A telephone handset as claimed in claim 1 wherein the connection apparatus are each operable to connect the handset to a different form of wired or wireless network or link.

3. A telephone handset as claimed in claim 1 wherein the identification of valid handling options for making the requested call by the rules unit is determined by the identified source of an incoming call request or the identified destination of an outgoing call request.

4. A telephone handset as claimed in claim 3 wherein for outgoing calls this includes determining whether connection is possible or available via the or each connection apparatus.

5. A telephone handset as claimed in claim 3 wherein the identification of valid handling options is determined by at least one of:

reference to the time of the call request and the location of the handset.

6. A telephone handset as claimed in claim 1 wherein information relating to any or each of these criteria is stored in a suitable data storage unit, which is updated manually or automatically.

7. A telephone handset as claimed in claim 1 wherein the criteria used by the comparison unit are preset or automatically adjusted.

8. A telephone handset as claimed in claim 1 wherein the criteria used by the comparison unit are adjusted by a user of the handset or by an administrator and said adjustment is achieved by use of a user interface or in response to one or more calls or data messages received from an external source.

9. A telephone handset as claimed in claim 1 wherein the modes are implemented manually or automatically.

10. A telephone handset as claimed in claim 1 wherein the valid call handling options differ in respect of incoming or outgoing calls.

11. A telephone handset as claimed in claim 1 wherein for incoming calls, the handling options include any one or more of the following:

signaling the incoming call as usual, varying the signaling or omitting signaling;

automatically answering, diverting or dropping the call whether immediately, after a predetermined interval or after the playing of a recorded message;

automatically, dropping and returning the call whether immediately, after a predetermined interval or after the playing of a recorded message;

contacting one or more separate systems and modifying the configuration of those systems in response to at least one of the source of the incoming call, time at the device date at the device, source of call, destination of call, device location as determined geographically, device location as determined in relation to available data or cellular networks;

selecting an operating mode from the set of available operating modes; and

modifying the current set of rules used by the call handling engine.

12. A telephone handset as claimed in claim 1 wherein for outgoing calls, the handling options include at least one of:

blocking the requested call;

modifying the requested destination number whether by varying digits or otherwise;

diverting the requested call to an alternative destination;

making the call via a particular connection apparatus, connection network or link;

connecting the handset to a PBX from which further calls can be requested;

notifying one or more separate systems of the requested call notifying one or more systems of the connection status;

contacting one or more separate systems and modifying the configuration of those systems in response to at least one of the requested destination number, time and date at the device, source of call or destination of call, device location as determined geographically or in relation to available data or cellular networks;

selecting an operating mode from the set of available operating modes;

or

modifying the current set of rules used by the call handling engine.

13. A telephone handset as claimed in claim 1 wherein the handset indicates to a user which handling options have been enabled at one or more of the following times:

in advance of the requested connection, during the requested connection and after the requested connection.

14. A telephone handset as claimed in claim 13 wherein the indication is either automatic or may be in response to a user request.

15. A telephone handset as claimed in claim 1 wherein in the event of a failure to enable the top ranked handling option, the enabling unit may be operable to retry to enable the same option.

16. A telephone handset as claimed in claim 15 wherein in the event of continued failure to enable the top ranking option, the enabling unit is operable to attempt to enable the next highest ranking handling option.
