<p>A method, device and system for updating routing area identifier are provided by the embodiments of the present invention. The update method comprises that an access network device constructs a first routing area identifier update message including a ground routing area identifier; said access network device sends said first routing area identifier update message to the user equipment, so that said user equipment uses said ground routing area identifier to replace an air routing area identifier stored in the local. In the routing area identifier update method and the access point device provided by the embodiments of the present invention, a routing area identifier update message is built by the AP before the UE performs a service interaction with the core network, and the UE is indicated to update the stored air RAI to the ground RAI stored by the core network, thus the successful ratio of the service interaction is ensured and the quality of the service serving is enhanced.</p> |
