Abstract
A method of processing a handover request from a base station controller (BSC) of a GSM (Global System for Mobile communication)-type network. The method comprises the steps of passing a handover request with GSM-type parameters from a base station controller (BSC) through a Master Switching Center (MSC) of the GSM-type network to a UMTS core network (CN) and to a Radio Network Controller (RNC) of the UMTS (Universal Mobile Telecommunications System) network, translating the GSM-type parameters to UTRAN parameters in the Radio Network Controller (RNC), and allocating UTRAN resources in response to the translated parameters.
Claims12
A method of establishing Universal Mobile Telecommunications System (UMTS) communication between User Equipment (UE) and a UMTS network, wherein the User Equipment is in communication with a Global System for Mobile communication (GSM)-type network, the method comprising:
- forwarding UMTS Terrestrial Radio Access Network (UTRAN) parameter information to the User Equipment via the GSM-type network;
- and
- in the User Equipment, interpreting the UTRAN parameter information and initiating communication with the UMTS network.
User Equipment for a UMTS network arranged to communicate over both a GSM network and said UMTS network, and comprising:
- means for receiving UTRAN parameters for setting up a UMTS call from the GSM network;
- and
- means for initiating communication with the UMTS network based on said parameters to enable a GSM call to be handed over to the UMTS network.
A message or data packet in a GSM network containing UTRAN parameters for handing over a GSM call to a UMTS network addressed to User Equipment engaged in a GSM call and capable of switching to a UMTS call.
