Super-Charged network
Super-Charged network, also known as a Super-Charger network, is a telecommunications term that refers to a particular standardized implementation of a 3GPP 3G telecommunications network. 3GPP has standardized Super-Charger networks in TS 23.116, the Super-Charger technical realization, and defines a Super-Charged network as a "''UMTS network in which the Super-Charger mechanism is being used to optimise mobility management signalling''."
==Background==
A regular UMTS network can be retrofitted to provide Super-Charger support by providing Super-Charger support within each network entity. Once a network entity has been modified to support Super-Charger functionality it is referred to as a Super-Charged network entity. For example, a HLR with Super-Charger functionality would be referred to as a Super-Charged HLR.〔
In a regular telecommunication network environment, transferring from a previous network to a serving network (i.e. handing off) uses a substantial amount of signalling traffic. For 3GPP networks, when the user equipment (UE) enters the serving network from the previous network, the UE triggers a Location Update request to be sent from the UE to the serving network's VLR. The serving network's VLR passes the Location Update request to the UE's home network's HLR. The HLR then performs two operations: 1) sends a Cancel Location message to the previous network's VLR, in an effort to remove the subscriber's data from the previous network, and 2) sends an Insert Subscriber Data message to the serving network's VLR, in an effort to add the subscriber's information to the serving network. After acknowledgments from the respective VLRs have been received for these steps, the HLR will send a Location Update confirmation back to the serving network, which forwards it to the UE, thereby informing the UE that the location update processing is complete by all parties involved.〔
However, when the UE jumps back and forth between the previous and serving networks, the signalling overhead resulting from the frequent Location Update messages is substantial and the resulting traffic is burdensome to the network.〔
