    Abstract: A method is described, comprising: creating, at a coordinating server, a user page cache table, the user page cache table associates a user equipment (UE) identifier with a last known location of the UE and a virtual base station instance; creating, at the coordinating server, a neighbor relation table, the neighbor relation table associates each cell to neighbor cells; receiving, at the coordinating server from a core network, a paging message for a user equipment (UE), the paging message comprises a tracking area identity (TAI), the UE identifier, and the virtual base station instance; querying, at the coordinating server, in the user page cache table based on the UE identifier received in the paging message to identify the virtual base station instance and the last known location; forwarding, from the coordinating server to the last known location of the UE, the paging message based on the queried last known location.

    Abstract: Systems and methods are disclosed for a 3G gateway. In a first embodiment, a method is disclosed for a network, comprising: receiving a relocation request message at a home nodeB gateway (HNBGW), the HNBGW coupled to an operator core network, the relocation request message including a target super cell identifier and a user equipment (UE) identifier; sending a second relocation request message from the HNBGW to a coordinating node, the coordinating node having as its identifier the target super cell identifier; querying a lookup table at the coordinating node using the UE identifier to determine a target cell identifier; replacing, in the second relocation request message, the target super cell identifier with the target cell identifier to create a third relocation request message; and sending the third relocation request message to a target cell identified by the target cell identifier.

    Abstract: Systems and methods for MME adaptive selection are described. The method includes: initializing a health checkup algorithm at an eNodeB for each MME connected to as per configuration values; starting a health check timer for each MME; continuing with an Initial Attach procedure for incoming calls based on SAE-Temporary Mobile Subscriber Id (S-TMSI), (Globally Unique MME Identifier) GUMMEI, or capacity/load balancing considerations; on every UE attach attempt, incrementing a total calls count; and on every S1 AP Error Indication/no response from an ME, incrementing a total fail calls count; determining when the health check timer for an MME expires; calculating a failed calls/total calls percentage value. Based on the value of the timer, appropriate action is taken.

    Abstract: Systems and methods for improved paging are described. In one embodiment, a method is described, comprising: providing a combined database in a heterogeneous radio access network at a coordinating gateway between a plurality of radio access network nodes and a plurality of core network nodes; at the coordinating gateway, storing a first location of a user device in the combined database in association with a user device identifier and based on receiving a first user device registration request at a first radio access network; at the coordinating gateway, storing a second location of the user device in the combined database in association with the user device identifier and based on receiving a second user device registration request at a second radio access network; and querying the combined database for a last known location of the user device across both the first and the second radio access network.

    Abstract: A method and computer readable medium for identifying slow base stations and providing impact mitigation are described. In one embodiment, the method includes detecting that a first base station, using a first queue, is slow, wherein a slow base station is a base station that that cannot keep up with the rate at which a core node is generating update messages over a prolonged period; providing a slow base station queue; and moving the first base station from the first queue to the slow base station queue.
