Abstract

A system (2) and method for optimizing handoff processing in networks with fully collapsed base station routers is disclosed. In accordance with exemplary embodiments of the present invention, handoff processing is optimized by allowing base station routers (4, 20a, 20b) to automatically discover, and maintain lists (10, 24a, 24b) of, their neighbor base station routers. Using the list of discovered neighbor base station routers, a base station router polls its neighbors for a list of all active users. The base station router then polls the Context Transfer Server (CTS) database for these users' contexts (1226a, 26b). Accordingly, instead of polling the CTS database during handoff, the present invention allows a base station router to activate the context from local memory.
