Methods for informing subscribers of adjacent sites
First Claim
1. A method for informing a mobile device of adjacent sites in a RF communication system wherein the RF communication system comprises a first network and a second network comprising the steps of:
- at a mobile device in the first network of the RF communication system;
updating a signaling gateway with position information of the mobile device wherein the signaling gateway interfaces between the first network and the second network; and
receiving a list of adjacent sites in the second network from the signaling gateway.

12. A method for informing a mobile device of adjacent sites in a RF communication system wherein the RF communication system comprises a first network and a second network comprising the steps of:
at an adjacent site information gateway, wherein the adjacent site information gateway interfaces between the first network and the second network of the RF communication system;
maintaining knowledge of sites in the second network;
receiving position information from the mobile device, wherein the mobile device is in the first network;
determining a list of adjacent sites in the second network from the maintained knowledge and the received position information; and
sending the determined list to the mobile device. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method for informing a mobile device of adjacent sites in a RF communication system wherein the RF communication system comprises a packet data network and a channelized network comprising the steps of:
at a mobile device in the packet data network of the RF communication system;
receiving a list of multicast addresses from a gateway, wherein each multicast address is associated with a geographic area;
determining a multicast address based upon a position of the mobile device;
sending a join message to the packet data network to become a member of a multicast group associated with the determined multicast address wherein the gateway interfaces between the packet data network and the channelized network; and
receiving a list of adjacent sites in the channelized network from the gateway. - View Dependent Claims (20)
