Systems, methods, and devices for facilitating wireless communication
First Claim
1. A communication method of a radio access network node in a wireless communication system, the communication method comprising:
- receiving, from a communication device, a first message for establishing a communication connection;
sending the first message to a first core network node;
receiving, from the first core network node, a second message including information identifying a group of at least one core network node;
selecting a second core network node based on the second message; and
sending a third message including the first message to the second core network node,wherein the third message includes Information indicating that the first message shall not be rerouted, andwherein the information identifying a group of at least one core network node is the information indicating that the first message shall not be rerouted.

Abstract
A communication system is disclosed in which a base station receives, from a communication device, NAS signalling for establishing a connection via the base station. The base station forwards the NAS signalling to a default MME for setting up the connection to the default MME. The default MME sends, responsive to the base station forwarding the NAS said signalling, a message identifying an MME group to which the NAS signalling should be rerouted. The base station selects an MME based on the message identifying the MME group, and forwards the NAS signalling to the selected MME, and includes information indicating that the NAS signalling shall not be rerouted.
