Patent number: 8989001Abstract: Various topologies of a quality of service application controller and related techniques to optimize the communications performance an application executing on a device participating in a communications environment are disclosed. The communications environment may include a cellular network, an unlicensed spectrum network, or a combination of the two. The quality of service application controller observes one or more key performance indicators of the communications network, and retrieves a policy from a policy store specific to the application. The quality of service application controller then modifies the execution of the application and/or the configurable aspects of the communications environment to optimize the communications performance of the application.Type: GrantFiled: December 4, 2012Date of Patent: March 24, 2015Assignee: T-Mobile USA, Inc.Inventors: Pablo Tapia, Mehul Shah, Alexandru Catalin Ionescu

Patent number: 8923873Abstract: A telecommunication device having a network interface module that is operable to detect an action at a network-driven application of the telecommunication device, which uses broadband Internet access to carry out its primary application functions. The network interface module then determines whether the detected action initiates a data transfer request corresponding to an application-specific rule identifying a timing sensitivity of the network-driven application. Then, based on this determination, the network interface module identifies and triggers a transition to a designated radio resource control (RRC) connected mode channel for a data transfer of the network-driven application to another network device, to improve a user's quality of experience (QoE) by reducing latency associated with the data transfer.Type: GrantFiled: November 13, 2012Date of Patent: December 30, 2014Assignee: T-Mobile USA, Inc.Inventors: Pablo Tapia, Alexandru Catalin Ionescu

Publication number: 20140269611Abstract: Devices configured to initiate a handover of a communication session of a user device from an access network associated with unlicensed spectrum to a circuit-switched access network are described herein. The devices may provide a handover request to a server associated with the circuit-switched network, receive a response from the server indicating that the circuit-switched access network has been prepared for the handover, and instruct the user device connect to the circuit-switched access network to continue the communication session. The devices may initiate the handover responsive to measurement reports received from the user device.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Applicant: T-MOBILE USA, INC.Inventors: Alexandru Catalin Ionescu, Robert F.

Publication number: 20140181316Abstract: A system and method that allows mobile device applications to receive changes in registration status from application services that are accessed via an Internet Protocol Multimedia Subsystem (IMS). Applications on a mobile device subscribe to receive notifications of changes in registration status for requested services. When a change to the registration status of a service occurs, a notification message is transmitted to the application on the mobile device. Notifications of changes in status are thereby received by each application on a per-application-service basis. In some embodiments, when a request to register with an application service fails, the corresponding notification message includes a reason for the failure. In some embodiments, notification messages are originated by a registration manager that operates in the IMS and transmitted to an IMS client operating on a mobile device.Type: ApplicationFiled: December 17, 2013Publication date: June 26, 2014Applicant: T-Mobile USA, Inc.Inventor: Alexandru Catalin Ionescu

Patent number: 8676187Abstract: Methods that facilitate automatic selection of service bearers in a mobile based on user-initiated policies and service-provider-initiated policies set forth in a policy document are described herein. The mobile device initially receives a policy document from either the mobile device manufacturer or the service provider before the mobile device is provisioned on a communications network. The mobile device user and the service provider may make subsequent changes to the policy document. When a user-initiated policy change conflicts with a service-provider-initiated policy, the user-initiated policy change is disregarded in favor of the service-provider-initiated policy. The mobile device automatically selects an appropriate bearer based at least on the availability of service bearers in the current environment and the policies set forth in the policy document.Type: GrantFiled: February 8, 2012Date of Patent: March 18, 2014Assignee: T-Mobile USA, Inc.Inventors: Alexandru Catalin Ionescu, Giridhar Sreenivas

Publication number: 20130286227Abstract: The techniques and systems described herein are directed, in part, to interactions between one or more mobile device applications, mobile device modems (or communication hardware), networks, and other devices. In some embodiments, a device may record a video using a camera. The device may then increase a block size of a first portion of a frame in the video to create a modified video where the first portion includes a larger block size than a second portion of the frame of the modified video. The increased block size may reduce an amount of data used to transmit the modified video to another device using the network communication.Type: ApplicationFiled: March 15, 2013Publication date: October 31, 2013Applicant: T-MOBILE USA, INC.Inventors: Kevin Lau, Jie Hui, Pablo Tapia, Alexandru Catalin Ionescu

Publication number: 20130258966Abstract: An application controller of a telecommunication device to determine, for a packet flow of an application, a quality-of-service rule associated with the application is described herein. The application controller then configures a data bearer for a wireless communication stack of the telecommunication device with a quality-of-service specified by the quality-of-service rule and provides a packet of the packet flow for transmission to a remote recipient via the configured data bearer.Type: ApplicationFiled: March 15, 2013Publication date: October 3, 2013Applicant: T-MOBILE USA, INC.Inventors: Pablo Tapia, Mehul Shah, Alexandru Catalin Ionescu

Publication number: 20130239189Abstract: A bootstrap authentication framework may automatically provide stored authentication credentials to an application server on behalf of an application. The bootstrap authentication framework may receive an access request from a protocol handler to access the authentication credentials stored in a subscriber identity module (SIM) of the electronic device. The access request may be initiated by an application that uses the authentication credentials to access a network service on an application server. In turn, the bootstrap authentication framework may provide the authentication credentials to the protocol handler when a digital signature associated with the protocol handler indicates that the protocol handler is allowed to access the authentication credentials.Type: ApplicationFiled: March 6, 2013Publication date: September 12, 2013Applicant: T-Mobile USA, Inc.Inventors: Alexandru Catalin Ionescu, Adrian Buzescu

Publication number: 20080294729Abstract: An email object is provided that fulfills requirements defined in the OMA MEM Enabler, where email messages are represented as extensible markup language documents. Filters created using XPath allow an email client to indicate what email messages are to be advertised as new and later downloaded. Table of content information can also be provided without the need for downloading an entire email object first, as well as additional information about each body part. Therefore, referencing body parts for downloading email body parts step-by-step or for use in a reply/forward without download use case, as well as allowing for the downloading of alternative content (e.g., content-adaptation) is provided. Data synchronization protocols are used to allow the email client to keep an equivalence relationship between main email storage on the email server and local mail storage on the email client side when transferring email messages between the email client and email server.Type: ApplicationFiled: May 22, 2007Publication date: November 27, 2008Inventors: Catalin Ionescu, Zoltan Ordogh
