Title: Modular block switch assembly
Inventor: MENDELSON JAY J
IPC: H01H9/00
Filed: 2004-01-21
Abstract: An improved rocker-type switch has a toggle member pivotably mounted on a central pivot member in a frame of a top housing part joined to a bottom housing part holding switch contacts in a modular block subassembly. A pair of movable contact arms is actuated by spring-biased actuator members held in the central pivot member. The modular block subassembly has an insulative top block member, a top switch contact plate with switch contacts on upright tabs inserted through slots in the top block member, an insulative bottom block member sandwiching the top switch contact plate, and a bottom switch contact plate having switch contacts on upright tabs inserted through slots in the bottom and top block members, forming a pair of opposing switch contact positions for the movable contact arms. The switch contact plates have clip portions for inserting the tabs of respective switch contact terminal plates therein. For different switch configurations, e.g., single-pole, double-pole, 3-way, or 4-way operation, the switch contact plates are changed, but the same block subassembly and other parts can be used, thereby minimizing change of the surrounding parts, limiting insulative molding costs, eliminating tolerance stack-up, and facilitating assembly through automation.

Title: Selecting ggsn in shared mobile network
Inventor: HAUMONT SERGE
IPC: H04W28/00
Filed: 2003-01-07
Abstract: The invention relates to the packet switched portion of a mobile communications system in which two or more network operators share the same network. To allow the operators to compete with each other, they usually have a gateway node (GGSN1, GGSN2) of their own, although they share the serving node (SGSN1). In order to enable the selection of the gateway node (GGSN1, GGSN2), the invention involves maintaining information about predefined partner networks, i.e. shared networks an operator has in addition to its own networks. On the basis of the information a mobile station (MS2) can be connected to a gateway node (GGSN2) of its home network (PLMN2), provided that the visited network (PLMN1) is a partner network of the home network (PLMN2).  A visiting mobile station from outside the partner networks, however, can be connected to the visited gateway node (GGSN1).
