Abstract

Methods and apparatuses are provided that facilitate establishing an interface for communications between access points. Where access points operate in a same local or enterprise network, an interface can be established via the local or enterprise network instead of (or in addition to) a wireless operator network. A source access point can determine an address over which to request establishment of the interface based at least in part on an identifier of a target access point. In another example, target access point can determine an address to provide to the source access point for establishing the interface based at least in part on an identifier of the source access point.
