  • Patent number: 8577395
    Abstract: Apparatus, and an associated method, for facilitating paging of an access terminal operable in a radio communication system. The access terminal detects a first page message that does not include an access sequence identifier. The access terminal responds to the first page message without waiting for detection of a second page message that includes an access sequence ID. The response to the first page message includes an access sequence ID retrieved from a shared pool of access sequence IDs stored at the access terminal.

  • Patent number: 8520518
    Abstract: Techniques for controlling wireless network operations associated with a flow control process of a wireless network involving a data session established between a mobile station and a service node. The network processor examines quality of service (QoS) data associated with the data session. The network processor causes the flow control process to be bypassed for the mobile station based on the QoS data indicating that the data session is associated with a predetermined traffic class (e.g. background traffic class). This serves to prohibit the flow control process from stopping the flow of data packets in the data session without terminating the data session based on detection of an out-of-coverage condition. Otherwise, the network processor allows the flow control process to be performed for the mobile station based on the QoS data indicating that the data session is not associated with the predetermined traffic class.

  • Patent number: 8457660
    Abstract: A technique for conserving power in a mobile communication device operative in a wireless communication network is described. The mobile device identifies a condition to change a parameter in the wireless communication network. However, the mobile device delays for a period of time until an expected message used for registration is to be sent to the wireless communication network. The mobile device provides the parameter within the expected message used for registration, and causes the expected message used for registration to be transmitted to the wireless communication network.

  • Patent number: 8447877
    Abstract: In accordance with the teachings described herein, systems and methods are provided for always-on wireless IP communication. An access provider network (APN) that includes an always-on packet data serving node (PDSN) may be used to communicate over a wireless communication link with a mobile station. The PDSN may include an inactivity timer and may be used to set the inactivity timer to an inactivity timer starting value and send a starting value estimate to the mobile station over the wireless communication link, wherein the starting value estimate is a function of the inactivity timer starting value. The mobile station may include an inactivity timer estimate and may be used to receive the starting value estimate and set the inactivity timer estimate to the starting value estimate. The mobile station may also be used to reset the inactivity timer estimate to the starting value estimate when the mobile station communicates with the APN.

  • Patent number: 8391448
    Abstract: A voicemail system apparatus produces a voicemail notification message corresponding to a voicemail message received and saved at a voicemail system, and causes the voicemail notification message to be sent to a mobile device. Subsequently, the apparatus causes a voicemail deletion notification message to be sent to the mobile device, where the voicemail deletion notification message indicates that the voicemail message will be deleted by the voicemail system. In response to expiration of a voicemail message time expiration period associated with the voicemail message, the apparatus deletes the voicemail message at the voicemail system. On the other hand, prior to expiration of the voicemail message time expiration period, and in response to receiving a save command from the mobile device for resaving the voicemail message, the apparatus saves the voicemail message at the voicemail system and updates the voicemail message time expiration period.

  • Patent number: 8364178
    Abstract: An apparatus, and an associated methodology for a communication system in which an access terminal is paged by a page sent on a paging channel. Hashes are generated by a hash generator at an access network to identify where in the paging message that page indications are to be positioned. And, hashes are generated at the access terminal to identify where in a received page that page indications are located.

  • Publication number: 20130022198
    Abstract: A method for establishing a link key between correspondents in a public key cryptographic scheme, one of the correspondents being an authenticating device and the other being an authenticated device. The method also provides a means for mutual authentication of the devices. The authenticating device may be a personalized device, such as a mobile phone, and the authenticated device may be a headset. The method for establishing the link key includes the step of introducing the first correspondent and the second correspondent within a predetermined distance, establishing a key agreement and implementing challenge-response routine for authentication. Advantageously, main-in-the middle attacks are minimized.

  • Publication number: 20130016840
    Abstract: A method of providing certificate issuance and revocation checks involving mobile devices in a mobile ad-hoc network (MANET). The wireless devices communicate with each other via Bluetooth wireless technology in the MANET, with an access point (AP) to provide connectivity to the Internet. A Certificate authority (CA) distributes certificates and certification revocation lists (CRLs) to the devices via the access point (AP). Each group of devices has the name of the group associated with the certificate and signed by the CA. A device that is out of the radio range of the access point may still connect to the CA to validate a certificate or download the appropriate CRL by having all the devices participate in the MANET.

  • Publication number: 20130005364
    Abstract: An apparatus, and an associated methodology, for facilitating paging of a mobile station pursuant to a two-step paging procedure. A unique identifier of the mobile station that is to be paged is hashed into a first group of hashed values and at least a second group of hashed values. The first group of hashed values are used by page message generator to generate a page on a first paging channel. And, the second group of values are used by a page message generator to generate a page on a second paging channel. All of the bits of the unique identifier are sent to page the mobile station. The mobile station determines therefrom whether the mobile station has been paged.
