Abstract: Methods and systems for handling of an inbound Stream Control Transmission Protocol (SCTP) packet at an SCTP load balancer (SCTP LB) are described. In one embodiment a method includes receiving, at the SCTP LB, an SCTP packet; determining, by the SCTP LB, which tunneling mechanism to use for the SCTP packet; and tunneling the SCTP packet to a correct back-end server for further processing of the SCTP packet.

Abstract: Systems, methods and computer software are disclosed for handling Stream Control Transmission Protocol (SCTP) packets with T-bit set at an SCTP load balancer. In one embodiment a method is disclosed, the method including embedding bits in an SCTP verification tag during SCTP association to identify a correct backend-server instance; parsing the verification tag to obtain an embedded instance number of the backend server; and routing, based on the embedded instance number, the SCTP packets to a correct backend server for further processing.

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.

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 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.
