Abstract
A method of communication mode change notification includes detecting (201), by a communication unit having an identification (ID) within a communications system having an infrastructure, that the communication unit's user initiated a communications mode change from a first communication resource to a second communication resource having an identity. The communication unit transmits (209) to the infrastructure a notification message including the ID and the identity of the second communication resource.

A method comprising the steps of:
- detecting, by a communication unit having an identification (ID) within a communications system having an infrastructure, that the communication unit's user initiated a communications mode change from a first communication path having a home system to a second communication path having an identity, wherein the infrastructure is affiliated with the home system of the first communication path;
- transmitting, by the communication unit to the infrastructure, a communications mode change message including the ID and the identity of the second communication path.

- determining, based on the identity of the first communication path, whether the infrastructure needs to be informed of the communications mode change;
- if the infrastructure needs to be informed of the communications mode change, transmitting, by the communication unit to the infrastructure, a communications mode change message including the ID and the identity of the second communication path.
