Concentrator for multiplexing access point to wireless network connections
Systems and methodologies are described that facilitate multiplexing communications from multiple downstream access points to one or more mobility management entities (MME). In particular, a concentrator component is provided that can establish a single transport layer connection with an MME along with multiple application layer connections over the single transport layer connection for each of multiple downstream access points and/or related mobile devices. The downstream access points and/or mobile devices can provide identifiers, such as tracking identifiers, to the concentrator component, which can utilize the identifiers to track communications with the MME. In this regard, the MME can send paging messages, and the concentrator component can determine downstream access points related to the paging messages based on a stored association with a tracking identifier in the paging message.
