  • Publication number: 20100057485
    Abstract: Methods and apparatus enabling a wireless network to provide differentiated services to a machine-to-machine (M2M) client. In one embodiment, the wireless network comprises a UMTS network, and the Home Location Register (HLR) entity identifies subscriptions as machine-to-machine (M2M) enabled devices based on flags or other descriptors associated with each M2M device, and imposes one or more rule sets (e.g., service restrictions) based on this identification. The classification of M2M devices within the HLR may optionally include additional capability or profile data for the M2M device (e.g. static, low mobility, low data activity, etc.). Various other network entities may use the M2M identification to modify the delivered data service, so as to optimize network resources. Furthermore, monitoring of M2M client behavior can be used to detect and notify the network operator of abnormal, fraudulent, or malicious activity. Business methods utilizing the aforementioned methods and apparatus are also disclosed.

  • Publication number: 20100027787
    Abstract: Apparatus and method for generating a traffic encryption key includes generating a traffic encryption key for encrypting data transmitted as part of a service, the traffic encryption key having a validity equal to a traffic encryption key validity time period; checking whether a period for the service is longer than the traffic encryption key validity time period; and if the period of the service is longer than the traffic encryption key validity time period, ascertaining a residual period which indicates by what period the service is longer than the traffic encryption key validity time period of the traffic encryption key; generating a residual traffic encryption key which is used for encrypting data transmitted as part of a service; ascertaining a residual traffic encryption key validity time period which indicates for how long the residual traffic encryption key is valid; and associating the residual traffic encryption key validity time period with the residual traffic encryption key.

  • Publication number: 20100002582
    Abstract: Methods and apparatus that enable a wireless network to detect and manage impending congestion events caused by a plurality of mobile devices attempting to access the network in a brief space of time. In one embodiment, the network comprises a 3g (UMTS) cellular network, and includes a congestion management and avoidance entity that preemptively triggers a collision mode upon detecting an impending congestion event. This mode advantageously reduces processing burden on the base station by causing the mobile devices (UEs) to halt current access attempts, and invoke a multiple access scheme (e.g., wait a random amount of time before attempting further access attempts). The comparatively early detection and avoidance of collisions reduces the mobile device's power consumption, while addressing congestion events early in the wireless communication process so as to maintain optimal network conditions.

  • Publication number: 20090305671
    Abstract: Methods and apparatus that provide user access control within wireless networks such as those having both fixed and portable nodes. In one embodiment, the network comprises a 3G cellular network or Interworking WLAN (iWLAN), and the portable nodes comprise Home Node B (HNB) base stations. The HNB is configured to authenticate new users, and provide network access while still maintaining user privacy. The portable nodes also may operate in a number of different operating modes which provide different functional control over user access. In one variant, an easy-to-use owner-assigned ID based access control mechanism with a reliable unambiguous user ID is utilized. Methods for providing access control across differing network architectures and protocols, such the aforementioned iWLAN, and business methods, are also described.

  • Patent number: 7567654
    Abstract: A communication link from a first telecommunication device to a second telecommunication device is established via a telecommunication network. Initially, a plurality of multi-media objects, which are associated with a first telecommunication subscriber, are stored together with a respective reference number in the telecommunication network. An allocation representation of at least one data set is also determined, the representation indicating a specific call receiver with reference to a specific reference number of a multi-media object. Subsequently, a link set up request is sent from the first telecommunication device associated with the first telecommunication subscriber to the telecommunication network, the link set up request indicating that a communication link should be set up between the first telecommunication device and the second telecommunication device associated with a selected call receiver.

  • Patent number: 7561675
    Abstract: A communication link from a first telecommunication device to a second telecommunication device is established via a telecommunication network. Several multimedia objects of a telecommunication user are stored in the second telecommunication device along with a reference number. An allocation map is defined which indicates allocation of a specific call receiver to a specific reference number of a multimedia object. A request is then sent from the first telecommunication device associated with the first telecommunication user to the telecommunication network, the request indicating that a communication link should be established from the first telecommunication device to the second telecommunication device allocated to a selected call receiver.

  • Publication number: 20090176522
    Abstract: A method for carrying out a survey of a plurality of participant communication devices, and corresponding communication devices. In order to carry out a survey of a plurality of participant communication devices, each of these communication devices is successively assigned an exclusive transmission right to transmit at least one useful message during an authorization period, on the basis of a specific request signal, while the other participant communication devices are only assigned a reception right to receive at least one useful message. The communication device authorized to transmit determines a time window for each participant communication device to respond to the survey, within which the respective participant communication device can transmit its response signal in that it sends at least once its own specific request signal as response signal in order to request the exclusive transmission right.
