  • Patent number: 10477394
    Abstract: A wireless communication device communicates with a GPRS wireless network where ciphering has gone out of sync between the wireless communication device and the wireless network. The wireless communication device triggers an authentication procedure that re-synchronizes the ciphering. Following the trigger, the wireless communication device and the wireless network continue the authentication procedure so that ciphering parameters can be negotiated again and data communication can resume.

  • Patent number: 9532372
    Abstract: In one aspect, the invention provides apparatuses and methods for wirelessly transmitting application data utilizing priority information for each radio link control (RLC) data block transmitted. Advantageously, the application data with a relatively high transmission priority is not substantially delayed by the transmission of application data with substantially lower transmission priorities.

  • Patent number: 8619665
    Abstract: Solutions are described that enable a user equipment (UE) for a communication system always to derive required identifiers using an international mobile subscriber identity (IMSI) even when the UE has only a subscriber identity module. One solution is based on a table, or list, that is maintained in the UE. Another solution is based on always taking a predetermined number of digits of the IMSI. Yet another solution is based on try-and-fail signaling. In consequence, the UE does not always need to know how many digits of the IMSI are used to indicate a mobile network code, which in some situations is impossible to know anyway.

  • Patent number: 8351973
    Abstract: A mobile station receives data for sending to a destination device and determines whether to send the data to the destination device via either short message service (SMS) over service access point identifier 0 (SAPI-0) or SMS over SAPI-3, where SAPI-0 and SAPI-3 comprise different service access points associated with a data link layer of a mobile network. The mobile station selectively sends the location information to the destination device via either SMS over SAPI-0, or via SMS over SAPI-3, based on the determination.

  • Publication number: 20100278164
    Abstract: A method comprising operating a base station is disclosed. The operating consists of providing synchronisation for mobile stations; and broadcasting information comprising information about an access point enabling generic access network, GAN, communication, from the base station operating a pure broadcasting telecommunication cell. An access area of the access point and the pure broadcasting telecommunication cell cover essentially the same area. Therefore, mobile stations able to receive the broadcasting information become aware of accessibility to the access point. Corresponding base station, mobile station, telecommunication system, and computer program are also disclosed.

  • Publication number: 20020119774
    Abstract: A method for selecting a public land mobile network to serve a mobile station includes the step of receiving at the mobile station a list of data associated with networks neighboring the PLMN currently serving the mobile station. A new PLMN to serve the mobile station is selected based upon the list of data, and the mobile station changes to the selected new PLMN.
