1. A method, comprising:
creating, at a 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; wherein the virtual base station instance manages a plurality of base stations of the radio access technology presented by the virtual base station instance;
creating, at the server, a neighbor relation table, the neighbor relation table associates each cell to neighbor cells;
receiving, at the server from the core network, a paging message for a user equipment (UE), the paging message comprising a tracking area identity (TAI), the UE identifier, and the virtual base station instance;
querying, at the 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; and
forwarding, from the server to the last known location of the UE, the paging message based on the queried last known location for the UE identifier received in the paging message,
thereby making efficient use of radio resources and computing resources to page the UE; wherein the virtual base station virtualizes a plurality of different base stations to a core network using a single identifier.
