Abstract: Allow adaptive automatic detail diagnostic log collection for self - diagnosis and auto -recovery. In an embodiment, a group communication server determines that a fault has occurred with a group communication between wireless communication devices. The group communication server determines a set of events to log based on the fault, and instructs components that host the group communication to begin logging a set of events. Upon determining that logging the set of events can no longer be performed, such as due to too high of a load within a component of the group communication, the group communication server adapts the logging by logging a second set of events that will not cause too high a load, and can dynamically when resources become available. In an embodiment, a second event may be logged before a first event because no resources (CPU memory or buffer is in overflow or load is high at a node) are available for logging the first event now. Only after determining that the first event can be logged, the logging begins for the first event.

Abstract: Embodiments are directed to selecting a physical layer for an access terminal's (AT's) participation in a communication session. In an embodiment, the AT can register its priorities for multiple physical-layer systems as well as contact information by which an application server can contact the AT over each system. The AT selectively updates the system prioritization and/or contact information. When the AT joins or initiates a communication session, the application server supports the AT on a highest-priority system through which the AT can be contacted. The system supporting the AT's session can change upon request by the AT, the initiative of the application server and/or a detected triggering event. In a further embodiment, multiple systems can be used concurrently to support the AT's session, such that the AT can send and/or receive signaling and/or media for at least a portion of the communication session over the multiple systems concurrently.
