  • Apparatuses and methods for coordinating communication operations associated with a plurality of subscriber identities
    Patent number: 11382003
    Abstract: A mobile communication device including a Radio Frequency (RF) device and a controller is provided. The controller is coupled to the RF device and configured to allocate the RF device to selectively communicate with a Packet Switched (PS)-based network using a first subscriber identity or with a service network using a second subscriber identity, and ignore a paging message associated with the first subscriber identity during an ongoing on-demand service associated with the second subscriber identity.
    Type: Grant

  • Proxy server, computer program product and methods for providing a plurality of internet telephony services
    Patent number: 8588215
    Abstract: A proxy server including a system manager and a database is provided. The system manager includes an internal registrar module, an external registrar module, a session manager module and a signal routing module. The internal registrar module provides an internal register service for a plurality of nodes in a first service network. The external registrar module registers at an internet service provider providing network services in a second service network. The session manager module manages session processes in the first service network and the second service network and manages the network services shared between the registered nodes. The signal routing module routes control signals of the session processes between the first service network and the second service network. The database stores information related to the registered nodes.
