1. both terminals are switched on and connected
2. both terminals are “on hook”
3. the terminal has been “off hook” within a predetermined timeout period.
The process 25 for determining availability of the users 3, 6 operates as shown in FIG. 3. The status of both the calling party 3 and called party 6 are checked from time to time (either periodically 30 as represented in FIG. 3, or by simply cycling through all callback requests in turn). Both the calling party 3 and called party 6 are checked to determine whether the user is connected (313, 316) and on hook (333, 336). If a “timeout” flag has been set (343, 346) a further check is made (353, 356) to determine if the user has gone from “off hook” to “on hook” within the predetermined timeout period. If all the checks 313, 316, 333, 336 and (if applied) 353, 356 are positive, the callback alert 27 is sent to the calling party 3, which initiates a new call attempt 200, as shown in FIG. 2.
This embodiment increases the likelihood that a callback alert is only sent when it is likely to succeed in connecting the parties. However, at the time of the call attempt, the second user 6 may be connected to the network (not busy or switched off) but using a terminal 6 a and/or connection 7 having limited capabilities. If the first user 3 a attempts to send the other user 6 a a large quantity of data which would take a very long time to download, or to attempt to discuss visual data not readable on the terminal 6 a, the call, although connected, will be unsuccessful in achieving the intentions of the caller 3 a. It would be preferable for the user 3 to wait until the called party 6 is using a more suitable terminal 6 b and or connection 8. There is also the possibility that when these conditions are met, the caller himself may have moved to a less suitable connection 3 b.
FIG. 4 illustrates an improved callback process which improves the success of the call attempts by ensuring that both users are connected by way of terminals and connections suitable for the proposed task. In this process the availability criteria 263, 266 are modified to include physical characteristics of the connection such as the type of terminal in use, and the available bandwidth (tests 323, 326) These criteria may be set by the calling party according to the nature of the communication required. For example, if the caller wishes to transmit a large data file, but it is not urgent, a callback may be requested for a time when both parties are connected to high bandwidth connections 4, 8. (It may also be appropriate to require that the called party's terminal 6 b has sufficient memory to accept the data). If a video conference is required, a callback may be requested for a time when both parties are connected to terminals 3 b, 6 b having audio-visual capability, and appropriate bandwidth to support it.
12. A method according to claim 7, wherein the criteria for generating a callback alert are modified if a first alert fails to result in a completed call.
