  • Patent number: 9854504
    Abstract: In one embodiment, a method is provided for customization of a mobile communications device's data session retry mechanism in a wireless packet data service network. The mobile communication device requests activation of a data session with a node via the wireless network and receives a reject message via the wireless network in response to the request for activation of the data session, the reject message including a cause code. If the cause code corresponds to a no-retry behavior of the data session retry mechanism of the mobile communication device, the mobile communications device no longer requesting activation of a data session with the node.

  • Patent number: 9838923
    Abstract: Systems, methods, and software can be used to transmit data over a radio access technology (RAT). In some aspect, a data transmission using a first radio access technology (RAT) is initiated at a mobile device. A timer is started at a first value. When the timer expires, it is determined that data remains to be transmitted. In response to determining that data remains to be transmitted: the data transmission is suspended, and a search is initiated for a second RAT for transmitting the remaining data. The second RAT provides a higher data rate than the first RAT.

  • Patent number: 9628633
    Abstract: A method at a user equipment to verify enablement of data billing splitting using a virtual subscriber identity module platform (‘VSP’) service, the method including receiving a credential at the user equipment, the credential including an international mobile subscriber identity (IMSI) from a physical universal integrated circuit card (UICC) subscriber identity module (SIM) application; storing the credential on the user equipment; checking, at a VSP service module on the user equipment, whether the credential matches an IMSI of a UICC currently inserted into the user equipment; if the checking determines a match, enabling the data billing splitting; and if the checking determines a mismatch, preventing enablement of the data billing splitting.

  • Patent number: 9237509
    Abstract: Systems and methods for determining that a maximum number of IP sessions have been established are provided. There are instances when the mobile device transmits a request to the wireless network. According to an aspect, in the event that the maximum number of IP sessions is already established for the mobile device, the wireless network transmits a response indicating that the request cannot be fulfilled. The mobile device determines based on the response that the maximum number of IP sessions is already established, which allows the mobile device to determine the maximum number of IP sessions that can be supported so that IP sessions can be managed accordingly.

  • Patent number: 9154913
    Abstract: Methods and devices for implementing subsystem or functional aspect restrictions on a wireless handheld communication device. Data defining geographical boundaries of a restricted operating area is stored on the device. The present position of the device is ascertained and a determination is made whether the device is located within the restricted operating area. A restriction on the subsystem or functional aspect is imposed when it is determined the device is within the restricted operating area. The subsystem or functional aspect restriction can be communicated to the device via a wireless communication network. Additionally, the restrictions and boundaries can be communicated to the device as part of an IT security policy.
