Abstract: A method for producing a wafer interposer (210) for use in a wafer interposer assembly is disclosed. The wafer interposer (210) is produced by attaching solder bumps (140) to a lower surface of a support (120). First electrical terminals (130) are attached to an upper surface of the support (120) and substantially correspond to the solder bumps (140). First electrical pathways are provided that passes through the support (120) and connect the solder bumps (140) to the first electrical terminals (130). Second electrical terminals (310) are attached to the upper surface of the support (120). Second electrical pathways (320) connect the first electrical terminals (130) to the second electrical terminals (310).

Abstract: An integrated radio telecommunications network which integrates an ANSI-41 circuit switched network and a General Packet Radio Service (GPRS) packet data network to support a mobile station which operates in both the ANSI-41 network and the GPRS network. An interworking function interfaces a mobile switching center (MSC) in the ANSI-41 network with a serving GPRS switching node (SGSN) in the GPRS network by mapping circuit switched signaling utilized by the MSC into GPRS packet switched signaling utilized by the SGSN, and mapping GPRS packet switched signaling into circuit switched signaling. An interworking GPRS base station controller interfaces the SGSN with a GPRS/ANSI-136 base station which supports both ANSI-136 operations and GPRS operations. The interworking GPRS base station controller adapts the traffic signaling format utilized by the SGSN into an air interface traffic signaling format utilized by the GPRS/ANSI-136 base station.
