  • Patent number: 9007990
    Abstract: A packet-switched wireless communications network includes a mobile station and a radio network controller that are able to establish a radio connection therebetween. Messages are exchanges over one or more traffic channels to establish a packet-switched services session between the mobile station and the radio network controller. The radio connection is not closed until all messages for establishing the packet-switched services session have been exchanged between the mobile station and the radio network controller.

  • Publication number: 20120120937
    Abstract: A packet-switched wireless communications network includes a radio network controller that receives, from a mobile station, a mobile station identifier over a wireless link. The radio network controller provides packet-switched services without providing circuit-switched services. A session is established, based on the mobile station identifier, between the radio network controller and a packet data service node that provides an interface to a packet-switched network.

  • Patent number: 7889731
    Abstract: A system and non-transitory computer storage medium storing a computer program for delivering messages to a wireless access terminal are provided. A messaging center is in communication with a 1xEV-DO network. The messaging center is arranged to receive a message having a telephone number as a destination address for delivery to the wireless access terminal. The messaging center has a storage device and a central processing unit. The storage device stores a mapping between the telephone number, a mobile static identifier corresponding to a user of the wireless access terminal and a destination address corresponding to an IP address of the wireless access terminal in the 1xEV-DO network. The central processing unit is in communication with the storage device. The mapping between the telephone number and the IP address is based on a correspondence between the telephone number and the mobile static identifier.

  • Patent number: 7720056
    Abstract: A method and system including messaging center connectable to a first communication network and a second communication network. The messaging center is arranged to receive a message having a destination address based on the first communication protocol for delivery to a wireless access terminal. The messaging center has a storage device and a central processing unit in communication with the storage device. The storage device stores a mapping between a first destination address corresponding to a first communication protocol destination address of the wireless access terminal in the first communication network and a second communication protocol destination address corresponding to a destination address of the wireless access terminal in the second communication network.

  • Patent number: 7352768
    Abstract: A wireless communications network includes cell segments each having at least a first type wireless link and a second, different type wireless link. Network access equipment is able to hand off mobile stations between the first type and second type wireless links to balance the loading of the wireless links. In one example implementation, the first type wireless link is a 1×EV wireless link, and the second type wireless link is a 1×RTT or other CDMA 2000 wireless link. The carriers can be co-located within a common cell segment, or located within different cell segments.

  • Patent number: 7280510
    Abstract: A wireless communications system includes access networks and access terminals. Within each cell or cell sector, reverse links and forward links are defined between an access network and multiple access terminals in the cell or cell sector. Based on a reverse data rate threshold value calculated from noise measurements, the access network indicates to access terminals within its cell or cell sector whether activity on reverse links are to be increased or decreased.
