A system is disclosed for providing Open RAN CU-UP high availability, the system comprising: at least one active CU-CP; at least one active CU-UP in communication with the at least one active CU-CP; and at least one standby CU-UP in communication with the at least one active CU-CP; wherein when a message may be received from a CU-CP that detects a failure of the at least one active CU-UP, the at least one standby CU-UP may be configured to take over and become an active CU-UP, thereby providing failover redundancy for the at least one active CU-UP.

OpenRAN intelligent dynamic CU-UP scaling solution

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 for establishing indirect and/or dual connectivity between virtualized 5G gENBs and virtualized 4G eNodeBs for dynamic X2 is disclosed. In one embodiment a method includes virtualizing, with a HetNet Gateway (HNG), BBUs and home eNodeBs over a standard S1 interface; establishing the HNG as a macro interfacing an EPC on 3GPP standard interfaces; communicating with an MME over the S1 interface for control plane signaling; and communicating with SAEGW over a standard GTPU interface for a data plane.

ENDC connectivity with virtualized eNBs

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

Systems, methods and computer software are disclosed for resolving multiple contexts for a User Equipment (UE) in a wireless network. In one embodiment a method includes maintaining, for a coordinating node hosting a first Radio Access Technology (RAT) controller and a second RAT controller simultaneously, a centrally maintained database; determining, based on the contents of the centrally maintained database, when the UE is registering with the second RAT controller while currently registered with the first RAT controller; and sending, by the second RAT controller, a deregistration command to the first RAT controller the UE was registered with, wherein context is freed and wherein resources held at both the coordinating node and at a base station are freed.
