METHOD, DEVICE, AND SYSTEM FOR NOTIFYING MOBILE STATIONS PARTICIPATING IN A NON-LLE CALL OF NEW LLE CALL

摘要

A method of interoperating link layer encrypted (LLE) and non-LLE communications in a radio network include receiving, at a radio controller (RC), a new call request for an LLE call, determining that there are one or more currently active non-LLE calls, and causing a message to be transmitted on each channel carrying one of the one or more currently active non-LLE calls informing mobile stations (MSs) participating in the non-LLE calls that a new LLE call has been or is-to-be granted. MSs participating in one of the non-LLE calls and receiving the message determine from the message or via a call grant obtained via a control channel, whether the new LLE call is of interest, and if so, switching to a channel assigned to the new LLE call and participating in the new LLE call.
