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.

Systems and methods for remote scan and priority operations

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.

Methods and devices for supporting remote scan and priority operations

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.

Method and apparatus for accessing a wireless communication network

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.
