Method and apparatus for updating and using updated group aliases and incident IDs
First Claim
1. In a two-way radio frequency (RF) communications system having at least one fixed terminal, one or more channels, and a plurality of subscriber units, the method comprising, at a first subscriber unit:
- monitoring, on a first channel, for communications of a first group associated with a first group ID stored at the first subscriber unit to which the first subscriber unit is subscribed;
receiving an updated group alias assign message, addressed to the first group and including the first group ID, that maps the first group ID to an updated text-based group alias included in the updated group alias assign message, wherein the updated text-based group alias describes one or more of a location, purpose, and function of the first group and associated first group ID for a temporary period of time; and
displaying, on a display of the first subscriber unit, the updated text-based group alias, instead of the first group ID or a first group alias associated with the first group ID and stored at the first subscriber unit, during subsequent communications with the first group, the subsequent communications including the first group ID.

Abstract
An updated group alias, based on one or more of a location, function, and purpose of a group, is transmitted to a subscriber unit (SU) and displayed at the SU, in place of a previously provisioned group ID or group alias associated with the group, during communications with, or when the SU is tuned to, the group. An incident ID, associated with one or more groups and identifying an incident, is received and stored at a SU. The SU embeds the stored incident ID in all future communications with the one or more groups and, upon request, scans a set of groups and/or channels for communications having the incident ID embedded therein. An incident ID alias described one or more of a name, location, function, or purpose of the incident, may also be received and associated with the incident ID.

-
monitor, on a first channel, for communications of a first group associated with a first group ID stored at the first subscriber unit to which the first subscriber unit is subscribed; receive an updated group alias assign message, addressed to the first group and including the first group ID, that maps the first group ID to an updated text-based group alias included in the updated group alias assign message, wherein the updated text-based group alias describes one or more of a location, purpose, and function of the first group and associated first group ID for a temporary period of time; and display, on a display of the first subscriber unit, the updated text-based group alias, instead of the first group ID or a first group alias associated with the first group ID and stored at the first subscriber unit, during subsequent communications with the first group, the subsequent communications including the first group ID. - View Dependent Claims (15, 16)

17. In a two-way radio frequency (RF) communications system having at least one fixed terminal, a plurality of channels, an infrastructure device, and a plurality of subscriber units, the method comprising the steps of, at the infrastructure device:
-
receiving an association that maps a first group ID, associated with a first group, to a corresponding updated text-based group alias that describes one of a purpose and function of the first group and associated first group ID for a temporary period of time; and responsive to receiving the association, transmitting an instruction addressed to the first group and including the first group ID that all subscriber units that are currently subscribed to the first group are to temporarily associate the specified updated text-based group alias with the first group ID and to display the specified updated text-based group alias during subsequent communications with the first group, but to retain the first group ID in storage and continue to use the first group ID in the subsequent communications with the first group. - View Dependent Claims (18)
