Patent number: 8819499Abstract: Error information is sent from a terminal adaptor that accesses a wireless network to terminal equipment coupled to access the wireless network through the terminal adaptor. The error information is sent in response to existence of any one of a plurality of errors conditions with respect to access to the wireless network. The error information includes an error type identifying a domain associated with a source of the error condition being reported and an error code providing a reject error cause for the error condition. One of the error conditions may include an unsolicited error received by the terminal adaptor from the wireless network or when a request by the TA is ignored by the wireless network.Type: GrantFiled: June 9, 2011Date of Patent: August 26, 2014Assignee: AT&T Mobility II LLCInventors: Yunpeng Li, Inderpreet Singh Ahluwalia

Patent number: 8639290Abstract: Devices and methods are disclosed by which a smart card or UICC that is removably insertable into a wireless terminal will only allow operation in either a specific terminal or a specific set of terminals. A mechanism to restrict the set of terminals that a UICC will operate with based upon logic embedded in a memory within the UICC. The UICC receives specific information from the wireless terminal when the terminal is turned on. If the information received satisfies a plurality of rules or conditions stored within the UICC, the UICC functions normally and the terminal may be registered with the network. If the UICC is inserted in an unsupported terminal, the UICC will refuse to function normally. This provides a deterrent against UICC theft.Type: GrantFiled: September 25, 2009Date of Patent: January 28, 2014Assignee: AT&T Intellectual Property I, L.P.Inventors: Jason Brown, Inderpreet Singh Ahluwalia

Patent number: 8436840Abstract: Disclosed are devices and methods that relate to an LCD device responding to an AT command that solely activates the backlight of the LCD device. An LCD device is programmed to respond to two distinct backlight AT commands. One AT command turns the backlight on, and another AT command turns the backlight off. These backlight AT commands are programmed into LCD device testing equipment so that accurate photographs are taken of the LCD device, and results are improved. The backlight AT commands are also used as part of the programming for user-end applications.Type: GrantFiled: December 12, 2008Date of Patent: May 7, 2013Assignee: AT&T Mobility II LLCInventor: Inderpreet Singh Ahluwalia

Patent number: 8380207Abstract: A system and methodology that resolves complex mobility handling issues in Long Term evolution (LTE) networks, overlaid with Universal Mobile Telecommunications System (UMTS) macro and UMTS femtocells that share a common UMTS Absolute Radio Frequency Number (UARFCN), is provided. Moreover, an LTE user equipment (UE) includes a femto identification component that differentiates between the UMTS macro and UMTS femtocells by employing Location Area Code (LAC) data. In an aspect, the femto identification component ensures that the LTE UE connects to the UMTS femtocell as soon as the LTE UE enters the UMTS femtocell coverage area, even when the LTE radio frequency (RF) signal is deemed sufficient for communication. Further, the femto identification component ensures that the LTE UE stays connected to the LTE network, as long as possible, while outside of the UMTS femtocell coverage area.Type: GrantFiled: February 22, 2011Date of Patent: February 19, 2013Assignee: AT&T Mobility II LLCInventors: Yonghui Tong, Inderpreet Singh Ahluwalia, Arthur Brisebois, Yung Choi-Grogan

Publication number: 20120302239Abstract: The disclosed subject matter relates to an architecture that can provide enhancement with respect to circuit switched fall back. In particular, the architecture can reduce the signaling and delay of conventional systems that are necessitated by establishing a radio resource control connection prior to establishing the circuit switched fall back connection. For example, when user equipment is not in a radio resource control connected state at the time of a circuit switched fall back call, the radio resource control connection can be at least partially avoided by responding to a radio resource control connection request message with a radio resource control connection reject message that includes target cell reselection information.Type: ApplicationFiled: May 26, 2011Publication date: November 29, 2012Applicant: AT&T MOBILITY II LLCInventors: Weidong Hu, Inderpreet Singh Ahluwalia, Yung Choi-Grogan

Publication number: 20120280813Abstract: An apparatus includes a memory containing a subscriber entitlement profile for a subscriber to a wireless communications network. The apparatus includes a controller configured to provide an indication of whether the subscriber is entitled to a service based on the subscriber entitlement profile. The memory and controller may be included in an integrated circuit card. The service may be unassociated with a rate plan associated with the subscriber. The apparatus may include a service entitlement facility configured to access a service of the communications network based on a user request for the service and the indication. The service entitlement facility may be further configured to determine whether or not a subscriber is entitled to the service of the wireless communications network based on the subscriber entitlement profile stored in the memory and further configured to access the service if the subscriber is entitled to the service.Type: ApplicationFiled: May 5, 2011Publication date: November 8, 2012Inventors: Inderpreet Singh Ahluwalia, Weidong Hu

Patent number: 6606486Abstract: A text entry method simplifies entry of the text messages in a mobile phone having a limited number of entry keys. A word list is stored in the phone's memory. The word list is divided into a plurality of groups and each group is associated with a particular group key on the keypad. The user first selects a word group by pressing the corresponding group key. The user can then scroll through the words in the group to select the desired word. The selected word may optionally then be translated into a codeword and the codeword then transmitted to a remote location. Individual characters may also be selected and translated in a similar manner in some embodiments.Type: GrantFiled: July 29, 1999Date of Patent: August 12, 2003Assignee: Ericsson Inc.Inventors: Aaron David Cubbage, Inderpreet Singh Ahluwalia
