Title: X2 PROTOCOL PROGRAMMABILITY
Abstract:
A gateway for X2 interface communication is disclosed, comprising: an X2 internal interface for communicating with, and coupled to, a first and a second radio access network (RAN); an X2 language processing module for receiving messages from the first RAN according to a first X2 protocol and mapping the received messages to a second X2 protocol for transmission to the second RAN; and an X2 external interface for communicating with, and coupled to, a gateway in a a wireless telecommunications core network. The gateway may further comprise a database for storing a plurality of rules for performing mapping at the X2 language processing module, and a state machine for maintaining state of one of the first RAN or the second RAN, and an interpreter for executing executable code received as part of the received messages and altering the state machine based on the executed executable code, and a regular expression pattern matcher for identifying patterns in the received messages that are present in the first X2 protocol but not present in the second X2 protocol.
