Publication number: 20130252584Abstract: A method and article of manufacture to reactivate a user identity card for a mobile station that communicates with a network is described. The user identity card is initially activated with the network. The user identity card has a unique identifier. Activation includes communicating with the mobile station from the network and programming the user identity card with network parameters. The network parameters programmed on the user identity card are then cleared after a preset period of time. The user identity card is reset to an unactivated state and then the user identity card can be reactivated with the network.Type: ApplicationFiled: March 22, 2012Publication date: September 26, 2013Applicant: Cellco Partnership d/b/a Verizon WirelessInventors: Ruben CUADRAT, Praveen VENKATARAMU, Rama YADDANAPUDI, Warren Hojilla UY, Xuming CHEN

Patent number: 8533369Abstract: A smart card determines if the smart card has been inserted into a device, and retrieves a device identifier and at least one application configuration value from the device if the smart card has been inserted into the device. The smart card compares the retrieved device identifier and the at least one application configuration value with a device identifier and at least one application configuration value previously stored in the smart card. The smart card causes the retrieved device identifier and the at least one application configuration value to be sent to an Over The Air (OTA) server if the comparison indicates that the retrieved device identifier or the at least one application configuration value is different than the previously stored device identifier or the at least one application configuration value, so that the OTA server can supply application parameter changes to the mobile device for future device operation.Type: GrantFiled: May 16, 2012Date of Patent: September 10, 2013Assignees: Cellco Partnership, Verizon Patent and Licensing Inc.Inventors: Xuming Chen, Bjorn Lennart Hjelm, Praveen Venkataramu, Andrew Youtz

Patent number: 8503983Abstract: A method is performed by a user device and a smart card inserted into the user device. The method includes storing, in the smart card, information to permit the user device to communicate with a particular network; identifying a first smart card identifier associated with the smart card; identifying a second smart card identifier associated with a previous smart card inserted into the user device; comparing the first smart card identifier and the second smart card identifier to generate a first comparison result; pushing, by the smart card and to the user device, the information when the first comparison result indicates that the first smart card identifier matches the second smart card identifier; and obtaining, by the user device, access to the particular network using the information received from the smart card.Type: GrantFiled: June 18, 2012Date of Patent: August 6, 2013Assignees: Verizon Patent and Licensing Inc., Cellco PartnershipInventors: Xuming Chen, Bhaskar Srinivasiah

Patent number: 8494522Abstract: Identification of radio coverage of a mobile station (MS) via a pico cell, such as an IP-BTS in a user premises (e.g. residence or business customer location), enables a mobile/wireless service provider to differentiate between coverage under a pico cell and coverage under a macro network. In a disclosed example, when the MS requests registration/authentication through a pico cell, a related signaling message includes a pico cell identifier (pID). A home location register (HLR) is provisioned with a pID, so that the HLR can decide to accept or reject the registration/authentication requests. For example, if the particular MS is provisioned for services from a specific pico cell, the HLR will grant the registration/authentication and allow the network to process calls for the mobile station through the identified pico cell. This enables the provider to allow discounted services through pico cell, e.g. as a replacement for a landline.Type: GrantFiled: August 30, 2007Date of Patent: July 23, 2013Assignee: Cellco PartnershipInventors: Xuming Chen, Phillip Andrew Ritter

Publication number: 20130157700Abstract: A device receives, from an application server, a message destined for a user equipment, and reformats the message into a non-access stratum (NAS) transparent message. The device also provides, to a home subscriber server, a query for an identification of a mobility management entity serving the user equipment, and receives, from the home subscriber server, the identification of the mobility management entity serving the user equipment. The device further provides the NAS transparent message to the identified mobility management entity, where the mobility management entity forwards the NAS transparent message to the user equipment.Type: ApplicationFiled: December 20, 2011Publication date: June 20, 2013Applicant: VERIZON PATENT AND LICENSING, INC.Inventors: Xuming CHEN, Andrew YOUTZ, Ho Yin CHEUK

Patent number: 8260258Abstract: Provisioning of target related information into an IP Multi-media Subsystem (IMS) communications network, to provide lawful intercept, utilizes an interface between a lawful intercept server (LIS) and one or more of the Home Subscriber Servers (HSSs) of the network. The LIS provisions an HSS with target information for LI, with respect to a subset of the overall list of LI targets, that is to say with respect to those of targets homed on the respective HSS. The HSS provisions the target list for its subset down to Call Session Control Function elements (CSCFs) logically attached to that HSS, to enable each CSCF to intercept signaling messages relating to communication for identified target user equipment (UE) devices. The intercepted signaling enables the LIS to identify a location of a target UE device in an access network and instruct a network control point to intercept content of communications for that UE device.Type: GrantFiled: May 13, 2008Date of Patent: September 4, 2012Assignee: Cellco PartnershipInventors: Mingxing Li, Phillip Andrew Ritter, Xuming Chen
