Abstract:
1. A method for synchronizing interface information in a telecommunications system that includes a first radio access network (RAN) node, a neighboring RAN node, and a mobility management entity (MME) of a core network, wherein the first RAN node does not need to authenticate with the core network through a signaling exchange before the interface information is synchronized between the first RAN node and the neighboring RAN node, the method comprising: determining, by the first RAN node without performing an authentication with the core network through the signaling exchange, whether a condition for sending S1 interface information is fulfilled, the S1 interface information including information indicating that an S1 interface exists between the first RAN node and the MME; sending, by the first RAN node without performing the authentication with the core network through the signaling exchange, the S1 interface information to a neighboring RAN node through an X2 interface between the first RAN node and the neighboring RAN node responsive to the first RAN node determining that the condition for sending the S1 interface information is fulfilled; receiving, by the neighboring RAN node, the S1 interface information; and configuring, by the neighboring RAN node, interface information of the first RAN node in accordance with the received S1 interface information when no previous S1 interface information of the first RAN node existed in the neighboring RAN node, or, updating, by the neighboring RAN node, interface information of the first RAN node in accordance with the received S1 interface information when previous S1 interface information of the first RAN node existed in the neighboring RAN node.
