  • Patent number: 7263354
    Abstract: Provided is a method and system for enabling mobile devices, radio access networks (RANs), and core networks (CNs) based on different specifications and underlying technologies to communicate. The mobile device and the RAN may be based on one technology, such as a code division multiple access (CDMA) specification, while the CN may be based on another technology, such as a global system for mobile communications (GSM) specification. The method takes a CDMA message received by the RAN, converts it into a corresponding GSM message, and passes it to the CN. Alternatively, a new GSM message may be created. Similarly, a GSM message from the CN may be converted into a CDMA message (or a new CDMA message may be created) and the CDMA message passed on to the RAN. The method may also initiate a function or procedure in one portion of a network using one technology when a certain message is received from another portion of the network using a different technology.

  • Patent number: 7054661
    Abstract: The present invention provides a system and method for migrating a control of a wireless communication service provided to a mobile station (MS) in a first network depending on a first technology to a second network depending on a second technology. When receiving a request for the wireless communication service in the first network by a mobile switch center (MSC), at least one instruction is obtained to grant or deny the wireless communication service from a first control device in the second network, the first control device providing the instruction based on its communication to a management subsystem for the control of the wireless communication service. If the wireless communication service is granted, a second control device in the first network controlled by the first control device allows the MS to execute the wireless communication service with a receiver.

  • Patent number: 7016359
    Abstract: A method and system is provided to allow wireless systems to support many new voice and data services. An example of a service provided is the ability to switch a requested voice call into a packet data call and vise versa without the interaction of the user.

  • Patent number: 6772224
    Abstract: A method and system is provided for routing at least one message from one or more subscribers of a communications network in a network node, the network node having a plurality of processing cards (Pcards). First, at least one Pcard is designated to service messages from a predetermined set of subscribers. When receiving a message from a subscriber of the predetermined set, the Pcard that is designated for the subscriber is determined and the received message is routed to the determined Pcard. The Pcard also has an associated database containing profile information for the subscribers using the Pcard.

  • Patent number: 5978358
    Abstract: The switch capacity prediction process of the present invention collects operational measurements from the cellular switch. These operational measurements indicate the frequency of the call events processed by the switch. The other input/output (I/O) time used by the call processor to process messages not related to call processing is separated from the call processing I/O time. A relationship between the other I/O time and the sum of the call processing time and call processing I/O time is determined. A weighted average is determined from the summation of the products of: the frequency of events and the call processing time, the frequency of events and the call processing I/O time, and the other I/O time. The weighted average is then divided into the call processor occupancy time, in hours, to determine the switch capacity.

  • Patent number: 5828963
    Abstract: A micro-cellular radio communications system (microsystem) is arranged to re-use radio frequency channels which are assigned for use in a cellular radio system (macrosystem) in the same vicinity. The microsystem maintains a list of each frequency channel which is in current use in any microcell of the microsystem. In each microcell of the microsystem a signal characteristic, for example received signal strength, of each frequency channel, is repeatedly measured when the channel is not in current use in any microcell of the microsystem, and the measurements are used to determine a long-term statistical preference for re-use of a favoured set of the frequency channels in that microcell. For each microcell, the frequency channels in the favoured set are given a short-term order for actual use in dependence upon frequent measurements of the signal characteristic for the microcell regardless of whether or not the channel is in current use in any other microcell of the microsystem.
