1. A method performed by a first communication node, comprising:
receiving a request from a communication device to establish a first connection associated with a second connection previously established between the communication device and a second communication node, wherein the request comprises first authentication information generated by the communication device;
sending a message to the second communication node to retrieve context information of the communication device, the message comprising a cell identifier (ID) of a cell that is (i) associated with the first communication node and (ii) corresponds to a first public land mobile network (PLMN) indicated in system information of the cell, for determining second authentication information generated by the second communication node; and
establishing the first connection between the communication device and the first communication node based on a determination that the second authentication information matches the first authentication information, wherein the second authentication information is based on a predetermined subset of input parameters, and
wherein the predetermined subset of input parameters are based on a first PLMN value of a plurality of PLMN values, wherein the first PLMN value corresponds to the first PLMN that corresponds to the cell ID of the cell and is associated with the first communication node in the message.
