Method and system for address translation and aliasing to efficiently utilize UFMI address space
First Claim
1. A method for facilitating dispatch communications between a first subscriber on a first network and a second subscriber on a second network, the method comprising:
- providing the first subscriber with an inter-working urban fleet member identifier (UFMI);
providing the first subscriber with access to a set of global inter-working UFMIs;
mapping an address of the second subscriber on the second dispatch network to the UFMI, wherein the UFMI represents an address of the second subscriber on the first network; and
mapping the address of the second subscriber to a select one of the global UFMIs when the address of the second subscriber has been mapped by at least a predetermined number of users of the first network.

Abstract
An address server comprising a UFMI server application adapted to allocate an inter-working UFMI to an iDEN subscriber unit and map the inter-working UFMI to an external subscriber address. The inter-working UFMI is associated with an iDEN network, and the external subscriber address is associated with an external network. The address server includes an iHLR, a data storage storing a pool of reusable iDEN UFMIs and mapped pairs of iDEN UFMIs to external subscribers. The mappings are stored on a per user, per fleet or per account basis. The data storage also stores a pool of global iDEN UFMIs. Use of the inter-working UFMIs facilitates dispatch communications between the iDEN subscriber unit and the external subscriber.

8. An address server comprising:
-
a urban fleet member identifier (UFMI) server application adapted to allocate an inter-working UFMI to a subscriber unit and map the inter-working UFMI to an external subscriber address; and a data storage storing a cool of global UFMIs, wherein the inter-working UFMI is a global UFMI. - View Dependent Claims (9, 10, 11, 13, 14, 15)

12. The address server of clam 8 wherein the UFMI server application is further adapted to perform steps comprising:
-
assigning a global UFMI to the external subscriber address when a number of reusable inter-working UFMIs mapped to the external subscriber address exceeds a predetermined threshold; for each subscriber unit having an associated reusable UFMI mapped to the external subscriber address, notifying the subscriber unit of the global UFMI; and releasing each associated reusable UFMI.

16. A mobile device including logic for performing steps comprising:
-
receiving a request to store user information associated with an external subscriber unit; transmitting a request for an inter-working urban fleet member identifier (UFMI) to an address server, the request including a mobile device identifier and the user information; receiving a UFMI;
external address mapping; andstoring the mapping on the mobile device. - View Dependent Claims (17, 18, 19)

20. A communications system comprising:
-
an address server including a data storage storing a pool of inter-working urban fleet member identifiers (UFMIs) and a memory storing program logic for instructing the address server to perform steps including; receiving a request for an inter-working UFMI; authenticating the request; allocating the inter-working UFMI to a subscriber if the request is authenticated; and mapping the allocated inter-working UFMI to an external subscriber; and storing the mapping in the data storage. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
