  • Publication number: 20130017804
    Abstract: A system for efficiently transmitting requests for data access from a wireless communications device to a radio access network. Requests for data access may be aggregated to more efficiently use radio resources. Aggregated requests may not be transmitted until a total number of requests or size of aggregated requests exceeds a threshold. Regardless of aggregation, requests may be stored until a timer expires, and then transmitted to the radio access network. Request priority, environmental data, and device data may be taken into account in determining when to transmit requests for data access.

  • Patent number: 7912456
    Abstract: A voicemail system (100) has a wireless unit (102) for conveying wireless messages to multimode mobile devices (108) by way of a wireless communication network (106) operating independently of a telephony system (105) also capable of communicating with said devices, and a voicemail server (104) coupled to the telephony system and the wireless unit. The voicemail server is programmed to store (208) a message from a calling party when the multimode mobile device of the called party is inaccessible by way of the telephony system, construct (210) a voicemail notification corresponding to the recorded message, and transmit (218) a wireless message including the voicemail notification directed to a select multimode mobile device.

  • Patent number: 7593379
    Abstract: A method and system to provide service availability to multi-mode terminals in different access networks is presented. In an embodiment, a computer-readable medium includes instructions that, when executed by a computer, cause the computer to automatically enable first call forwarding prior to a wireless multi-mode communication terminal access from a first communication network to a second communication network, where first calls are redirected from a first directory number of the first communication network to a second directory number of the second communication network. The computer-readable medium also includes additional instructions that, when executed by the computer, cause the computer to automatically disable second call forwarding subsequent to the wireless multi-mode communication terminal access change when the second call forwarding conflicts with the enabled first call forwarding.

  • Patent number: 7406334
    Abstract: Mobile terminals, such as cell phones, having an internal memory and operating in a GSM wireless network environment with a SIM, store private content such as images, ring tones, buddy lists, email and the like, in the terminal memory. The private content is associated with the IMSI/MSISDN information of the content owner. The terminal correlates the IMSI/MSISDN information of the SIM with the IMSI/MSISDN information of the private content to grant access to the content only upon a positive content/SIM correlation.

  • Publication number: 20060045252
    Abstract: Devices, methods and systems for enhanced ringing features on communications terminals. Flexible user-established rules, customized in a subscriber profile database, enable the ring-tone to vary based on caller-id, caller priority, call-urgency (as determined by caller), call context and so forth. Call set-up logic applies the profile rules prior to completing the call set-up. “Buzz-tones” extend the basic distinctive ringing feature to the “silent” mode that is currently available on cell-phones, which is of particular utility to subscribers with hearing disabilities. Other kinds of alerts (audio/motion/visual) like flashing colors on a display, moving pictures and the like, and any combination of notification modes, are contemplated by alternative embodiments.
