Abstract

An apparatus and associated method employ the concept of a central busy list for coordinating the receipt of incoming calls to a subscriber subscribing to the calling services of separate first and second communication networks. The central busy list apparatus cooperates with the networks to register a current call by a subscriber serviced by the first network, to receive a request for interruption of the call serviced by the first network to allow the subscriber to receive an incoming call to be serviced by the second network, to send a request to disconnect to the first network when a priority of the current call is lower than the priority of the incoming call, and to deny interruption of the current call by the incoming call when the priority of the current call is higher.

Claims

1. In a multi-network communication system including at least a first and second communication networks, said first network servicing subscribers with a first set of call types of system serviceable call types and said second network servicing subscribers with a second set of call types of the system serviceable call types, a method for coordinating the receipt of incoming calls to a subscriber subscribing to the system serviceable call types of at least said first and second networks, comprising the steps of:

registering a current call associated with the first set of call types by a subscriber serviced by the first network;

receiving a request, from the second network, for interruption of the current call serviced by the first network to allow the subscriber to receive an incoming call associated with the second set of call types to be serviced by the second network;

sending a request to disconnect service to the current call to the first network when a priority of the subscriber to maintain access to the current call is lower than a priority of the subscriber to be given access to the incoming call; and

denying interruption of the current call by the incoming call when the priority to maintain access of the current call is higher than the priority to be given access to the incoming call,

wherein the first and second sets of call types are different system serviceable call types, and whereby said system serviceable call types comprise at least two of the following call types;

(a) telephone interconnect calls and circuit data calls serviced by a message switching center,

(b) dispach calls serviced by a dispatch application processor;

(c) packet data type call serviced by a packet data service system, and

(d) paging requests serviced by short message service switching system.

2. The method of claim 1, further comprising, upon completion of the step of receiving a request from the second network, the steps of:

prompting the subscriber when an incoming call request is received, and

assigning the associated priorities to the current and incoming calls on the basis of a priority election by the subscriber.

3. The method of claim 1, wherein the step or registering the current call includes the step of registering the call type of the current call serviced by the first network, and the steps of sending a request to disconnect and denying interruption include the step of comparing the call type of the incoming call and the registered call type of the current call.

4. The method of claim 1, wherein the steps of sending a request to disconnect and denying interruption are executed on the basis of a predefined service priority list associated with the subscribe.

5. The method of claim 1, wherein the step of registering is performed by a device adding a subscriber'"'"'s identification information to a central busy list,

when the current call is terminated, the method further comprising the steps of removing the subscriber'"'"'s identification information from the central busy list.

6. The method of claim 5, wherein said central busy list includes identification information for all subscribers currently involved in a call being serviced by either of the first and second networks and a queue of incoming calls for at least one subscriber currently involved in a call.

7. The method of claim 1, wherein said first network is a dispatch system network providing a group call to multiple subscribers at one time, said step of registering the current call involves the step of registering all the current calls of the individual subscribers associated with the group call.

8. The method of claim 7, wherein when an incoming call from the second network is received for one of the subscribers among said individual subscribers involved in the group call, the method further comprising the steps of prompting only said one subscriber of the incoming call request, and assigning a priority to the current and incoming calls on the basis of a priority election by said one subscriber.

9. In a multi-network communication system including a first communication network for servicing subscribers with a first set of call types of system serviceable call types and a second communication network servicing subscribers with a second set of call types of the system serviceable call types, a monitoring apparatus for coordinating the receipt of incoming calls to a subscriber subscribing to the system serviceable call types provided by at least the first and second networks, the apparatus comprising:

means for registering a current call associated with the first set of set types by a subscriber serviced by the first network;

means for receiving a request, from the second network, for interruption of the current call serviced by the first network to allow the subscriber to receive an incoming call associated with the second set of call types to be serviced by the second network;

means for sending a request to disconnect service to the current call to the first network when a priority of the subscriber to maintain access to the current call is lower than a priority of the subscriber to be given access to the incoming call; and

means for denying interruption of the current call by the incoming call when the priority to maintain access of the current call is higher than the priority to be given access to the incoming call,

wherein the first and second sets of call types are different system serviceable call types, and whereby said system serviceable call types comprise at least two of the following call types;

(a) telephone interconnect calls and circuit data calls serviced by a message switching center,

(b) dispatch calls serviced by a dispatch application processor;

(c) packet data type calls serviced by a packet data service system, and

(d) paging requests serviced by a short message service switching system.

10. The apparatus of claim 9, further comprising:

means for prompting the subscriber when an incoming call request is received; and

means for assigning the associated priorities to the current and incoming calls on the basis of a priority election by the subscriber.

11. The apparatus of claim 9, wherein the means for registering the current call includes means for registering the call type of the current call serviced by the first network, and wherein the means for sending a request to disconnect and the means for denying interruption include means for comparing call type of the the coming call and the registered call type of the current call.

12. The apparatus of claim 9, wherein the means for sending a request to disconnect and the means for denying interruption include a predefined service priority list associated with the subscriber.

13. The apparatus of claim 9, wherein the means for registering includes means for adding a subscriber'"'"'s identification information to a central busy list, and further includes means for removing the subscriber'"'"'s identification information from the central busy list when the current call is terminated.

14. The apparatus of claim 13, wherein said central busy list includes identification information for all subscribers currently involved in a call being serviced by either of the first and second networks and a queue of incoming calls for at least one subscriber currently involved in a call.

15. The apparatus of claim 9, wherein said first network is a dispatch system network providing a group call to multiple subscribers at one time, said means for registering the current call includes means for registering all the current calls of the individual subscribers associated with the group call.

16. The apparatus of claim 15, further comprising:

means for prompting only one subscriber involved in the group call of an associated incoming call request; and

means for, in response to said prompt, allowing said one subscriber to dynamically assign a priority to the current and incoming calls on the basis of a priority election made thereby.
