Title:
COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/029795
Kind Code:
A1
Abstract:
A system is described in which a default mobility management entity (MME) receives, from a base station, a request for setting up a communication connection to a mobile device having an associated usage type. The default MME sends, to the base station and responsive to the request, a message identifying a dedicated MME, to which the request should be re-routed, the dedicated MME having a supported service type corresponding to the usage type associated with the mobile device. The base station sends a response to the default MME, the response indicating whether re-routing to said dedicated MME is was successful or not (e.g. due to an overload of the dedicated MME). If the re-routing was not successful, the default MME attempts to serve the mobile device instead of the dedicated MME.
