Abstract: When a land mobile radio connection is unavailable for a subscriber device, the subscriber device may use an alternative connection. A gateway may be used to allow the subscriber device to connect to the zone controller of a land mobile radio network via an alternative network. The gateway may be configured to perform remote scan and priority operations, similar to the scan operations the subscriber device would ordinarily perform locally. The gateway may receive a scan list from the subscriber device and call notifications from the zone controller. Using the scan list, the gateway may evaluate the call notifications, determine whether they should be sent to the subscriber device, and send them to the subscriber device over the alternative connection. The gateway may be able to adjust the remote scan and priority operations based on receiving different scan lists from the subscriber device or by generating different versions itself.

Abstract: When a land mobile radio connection to a land mobile radio network is unavailable for a land mobile radio subscriber device, the subscriber device may connect to an alternative network using an alternative connection. The subscriber device may send a copy of a scan list to a gateway configured to perform remote scan and priority operations, similar to the scan operations the subscriber device may ordinarily perform locally. Using the received scan list, the gateway may evaluate the call notifications, determine whether they should be sent to the subscriber device, and send them to the subscriber device over the alternative connection to the alternative network. The subscriber device may receive call notifications over the alternative connection and join active radio calls over the alternative connection. The subscriber device may be able to alter remote scan and priority operations by dynamically altering and sending the scan list over the alternative connection.

Abstract: To address the need for more resource efficient methods of providing service in multi-RAN communication systems (600), various embodiments are described for informing a cross-paging RAN that a targeted remote unit (601) is not accepting a service request, for informing a serving RAN that the targeted remote unit is accepting the service request, and for informing an IMS (IP Multimedia Subsystem) network (611) that the targeted remote unit is moving from the serving RAN to the cross-paging RAN (or simply moving to another RAN without being cross-paged). Thus, embodiments such as those described herein can enable multi-RAN communication systems to more quickly release unneeded resources, to reduce the amount of unnecessary paging, and to minimize cross-paging when an IMS core network is available to deliver voice over IP (VoIP) calls.

Abstract: A communication system is provided that minimizes access message collisions when multiple mobile stations attempt to access a network after updating configuration information and/or access parameters information via a same overhead message by providing for each such mobile station to determine whether, or when, to convey an access message based on a time period corresponding to a wait for the overhead message by the mobile station.

Abstract: A method and apparatus for managing paging related delays between a mobile station and a base station is provided, which includes the use of a fractional slot cycle index. A first value for the slot cycle index, which is equal to an integer value less than a desired fractional slot cycle index value, is selected for use during a period of time corresponding to a determined proportion of a reduced slot cycle period, and a second value for the slot cycle index, which is equal to an integer value greater than a desired fractional slot cycle index value, is selected for use during a period of time corresponding to a remaining portion of the reduced slot cycle period.

Abstract: A system and method is disclosed to provide inter-packet-node paging between communication networks. The networks recognize whether inter-network paging is supported therebetween and advertise overlapping codes between networks having adjacent location areas. When the mobile station moves from the first network to the second network, the first network determines whether the second network shares an overlapping code therewith. If the networks share an overlapping code, the first network sends a paging request to the second network including link configuration information and the notification for the mobile station, wherein the notification can be delivered to mobile station in the second location area of the second communication network without the mobile station having to register in the second communication network.
