A method, computer readable media and system for providing X2 Gateway (GW) multi-cell support, comprising: are presented. In one embodiment a method includes providing a system having a Virtual Radio Unit (VRU) in communication with a Het Net Gateway (coordinating server); exchanging non-content X2 request messages between the VRU and the coordinating server; exchanging non-content X2 response messages between the VRU and the coordinating server; and wherein the non-content X2 request messages and the X2 response messages are used to communicate multiple cells served by the VRU to the coordinating server.

X2GW multi-cell support

A method is disclosed for providing distributed paging optimization, the method comprising: connecting a group of radio access network nodes, each supporting multiple small cells, to a gateway which acts as a virtual core network to the multiple small cells and acts as an eNodeB virtualizing the multiple small cells toward a core network; sending, by the gateway, in response to a paging request from the core network, a plurality of recommended cell IDs or base stations using a private information element (IE) in a paging request; and sending paging requests in response to the paging request from the core network to only the plurality of cell IDs or base stations recommended by the gateway.

Distributed paging optimization

Methods, systems and computer readable media are disclosed for providing optimized X2 cell reporting. A method includes selecting a subset of virtualized BaseBand Units (vBBU) vnodes to a macro peer that have either reported the X2 peer eNB as a neighbor, or host a cell that the X2 peer eNodeB (eNB) has reported as a neighbor while advertising the neighboring cells towards macro; and advertising cells of this subset of vBBU vnodes as served-cells in X2-Setup Request/Response towards a macro.

Optimized X2 cell reporting

Methods, systems and computer readable media are disclosed for operating a wireless network system. In one embodiment a method includes defining a plurality of Information Elements (IEs) relating to a retransmit timer value and a retransmit count; including, by the Mobility Management Entity (MME), the plurality of IEs in a first message sent to an eNodeB with a timer value and a retransmission count for the message; processing, by the eNodeB, the message, buffering the request, and starting a corresponding timer; and sending, by the eNodeB when a response from a User Equipment (UE) is not received before the timer expires, a stop retry message indication to the MME.
