  • Patent number: 7236582
    Abstract: A signaling transfer point (STP) (or Signaling Server Global (SSG)) is described herein which includes a processor and a mapping database that can depending on the direction of a message change the Origination Point Code (OPC) or the Destination Point Code (DPC) and the Circuit Identification Code (CIC) contained in the message. As such, the STP can receive a message from a foreign switch located in another telecommunications network and redirect the message that was originally destined for an old switch, which is in the process being removed or has been removed, to a new switch which now hosts the trunks previously connected to the old switch. The return traffic from the new switch is also processed by the STP so that when the foreign switch receives the message, it will appear like it originated from the old switch. As a result, the user of the STP can transparently consolidate switches without affecting the SS7 database contained in other carrier networks.

  • Patent number: 6731934
    Abstract: A wireless communications network, a home location register and a method are provided that have an improved signal strength arbitration scheme which can ensure that a mobile terminal is registered at the most appropriate mobile switching center. In particular, the home location register includes a database coupled to a processor capable of implementing a signal strength arbitration scheme that assigns a provisional quality value to a registration signal that was received from a mobile switching center which failed to include a quality parameter within the registration signal, wherein that mobile switching center may now be considered and possibly registered as the most appropriate mobile switching center to process a wireless call of a mobile terminal that broadcasted a registration access signal to a plurality of mobile switching centers.
