Methods and systems for concurrent receipt of incoming calls from a wide area cellular network and a private radio communications network
First Claim
1. A method for concurrent receipt by a mobile terminal of incoming calls from both a private radio communications network having a beacon channel and a wide area cellular network having a paging channel, comprising the steps of:
- monitoring for paging messages from the wide area cellular network at a first predetermined time interval corresponding to the paging channel of the wide area cellular network;
monitoring for beacon transmissions from the private radio communications network at a second predetermined time interval corresponding to the beacon channel of the private radio communications network;
selecting between executing said monitoring for paging messages step and said monitoring for beacon transmissions step when said first predetermined time interval and said second predetermined time interval conflict;
accessing the wide area cellular network when a paging message is received in said monitoring for paging messages step indicating receipt of an incoming call on said wide area cellular network; and
, accessing the private radio communications network when a beacon transmission is received in said monitoring for beacon transmissions step indicating receipt of an incoming call on said private radio communications network.

Abstract
Concurrent receipt of incoming calls from both a private radio communications network connected to a public switched telephone network and a wide area cellular network also connected to the public switched telephone network are provided by a radio communications mobile terminal supporting concurrent receipt of incoming calls from the two uncoordinated networks. The mobile terminal wakes up from a lower power sleep mode to monitor for paging messages on the paging channel of the wide area cellular network. The mobile terminal also wakes up to monitor for beacon transmissions from the private radio communications network on the beacon channel of the private radio communications network. When incoming calls are indicated as pending in either network, the mobile terminal accesses the network having an incoming call and receives the call. The mobile terminal may optionally deregister from the wide area cellular network when it establishes access to a private radio communications network and only periodically wake up from its lower power sleep mode to monitor for incoming calls on both the wide area cellular network and the private radio communications network.

11. A method for concurrent receipt by a mobile terminal having a sleep mode of incoming calls from both a private radio communications network having a beacon channel and a wide area cellular network having a paging channel, comprising the steps of:
-
periodically monitoring for paging messages from the wide area cellular network at first predetermined time intervals corresponding to the paging channel timing of the wide area cellular network; periodically monitoring for beacon transmissions from the private radio communications network at second predetermined time intervals corresponding to the beacon channel timing of the private radio communications network; selecting between executing said periodically monitoring for paging messages step and said periodically monitoring for beacon transmissions step when said first predetermined time interval and said second predetermined time interval conflict; accessing the wide area cellular network when a paging message is received in said periodically monitoring for paging messages step indicating receipt of an incoming call on said wide area cellular network; accessing the private radio communications network when a beacon transmission is received in said periodically monitoring for beacon transmissions step indicating receipt of an incoming call on said private radio communications network; and
,entering the sleep mode to conserve mobile terminal power when the mobile terminal is not performing said steps of monitoring or accessing the wide area cellular network or the private radio communications network.

12. A mobile terminal for concurrent receipt of incoming calls from both a private radio communications network having a beacon channel and a wide area cellular network having a paging channel, comprising:
-
receiving means for receiving said beacon channel and for receiving said paging channel; page monitoring means operatively connected to said receiving means for receiving paging messages from said wide area cellular network at a first predetermined time interval corresponding to said paging channel of said wide area cellular network; beacon monitoring means operatively connected to said receiving means for monitoring beacon transmissions from said private radio communications network at a second predetermined time interval corresponding to said beacon channel of said private radio communications network; and
,power control means responsive to at least one of said page monitoring means or said beacon monitoring means, said power control means comprising means for placing said mobile terminal in a lower power sleep mode in which said mobile terminal does not communicate with said private radio communications network or said wide area cellular network and means for placing said mobile terminal in a higher power active mode in which said mobile terminal monitors for communications from said private radio communications network or said wide area cellular network, at least during said first predetermined time interval or said second predetermined time interval. - View Dependent Claims (13, 14)
