Abstract
Methods are disclosed for sharing location and route information between communication units (e.g., talkgroup members) that are subscribed to a group location sharing service. The group location sharing service is event-based, such that the communication units may form a subset of a talkgroup desiring to actively participate or monitor an event. Communication units de-subscribe from the group location sharing service or talkgroup when they no longer desire to participate or monitor the event. Service levels may be determined for various subscribers to the group location sharing service. The service levels may include, for example, an information transmission service level and information reception service level that determine an amount, type, and/or timing of information to be sent or received by particular subscribers.
