An access management account that includes an access identifier may be used to control access to telecommunications services or applications. An access identifier is designated for obtaining access to multiple telecommunications services or applications, in which the multiple telecommunications services or applications are accessible to a user through multiple user accounts that are protected by account credentials. Once the access credential is designated, the access credential may be used to determine whether access to the one or more telecommunications services or applications is to be granted instead of using the account credentials of the multiple user accounts.

Identity and access management

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. In some embodiments, notification messages are originated by each application service and transmitted directly to subscribed applications.

System and method for subscribing for internet protocol multimedia subsystems (IMS) services registration status

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.

Application controller for quality-of-service configuration of a telecommunication device radio

A secure operating environment for a telecommunication device is disclosed, where a trusted execution environment (TEE) can establish both first secure communication (SC) channel between the TEE and a security-enabled SIM card, and a second SC between a service provider entity and Trustlet application, which is a component of the TEE of the telecommunication device. The telecommunication device may include a processor(s), an identification module, and a memory including the TEE and a normal operating environment (NOE). The TEE can be operated by the one or more processors to establish the first SC channel, authenticate a service identifier of the identification module, and establish the second SC channel, prior to an execution of the NOE.

Secure environment for subscriber device

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.

Bootstrap authentication framework

Techniques are described herein for deciding whether to unlock functionality of a telecommunication device based on one or more policies. A policy engine remote from the telecommunication device may receive, via a user interface associated with the policy engine, a request to unlock the functionality. The policy engine may then decide whether to unlock the functionality and, in response to deciding to unlock the functionality, may cause transmission of instructions to the telecommunication device to unlock the functionality.

Remote unlocking of telecommunication device functionality

A system and method to determine a type of wireless network that is to be used for an emergency communication session that is initiated at a mobile device. A Session Initiation Protocol (SIP) header is modified to introduce an emergency call mode preference (ECMP) field into the header. When a mobile device registers a session with an IP Multimedia Subsystem (IMS), the ECMP field is populated by the service provider with information that conveys the preferred network to use when an emergency communication session is initiated by a user of the mobile device. In the event of a subsequent request to start an emergency communication session using the mobile device, the mobile device utilizes the preferred network to establish communication.

Emergency call mode preference in wireless communication networks

Techniques to optimize video-call communications are disclosed. The link quality capability of a wireless video-call session and the requirements of the video-call session are determined. The link quality capability determination is based at least on measurements through the entire communications chain, including user, client device, operating system, application, air interface, cell sector, and backhaul parameters. Those parameters may be determined from static profiles, dynamically determined or be statistically derived. Client device response may include adapting the rate of data captured by a video camera, microphone, or other data capture device used in the video-call session. For video-conferencing scenarios, communications throughput is optimized by consolidating video streams.

Optimizing video-call quality of service

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. For example, the application's data throughput may be increased, the power draw of the application may be minimized, data requested by the application may be minimized, or the apparent response time of the application's response to a web service may be minimized.

Quality of service application controller and user equipment application profiler

A device-type locking procedure is disclosed, where a trusted execution environment (TEE) of a user device retrieves a telecommunication service plan type identifier stored on an identification module of the user device. The TEE of the user device then initiates a service authentication procedure for a telecommunication service provider of the user device, based on the received plan type identifier and in conjunction with an optional service plan provisioning process. A service plan indicated by the plan type identifier is subsequently compared to a designated user device service plan via the TEE. Based on the comparison results, a determination is then made as to whether the user device should be locked or unlocked, depending on the device's current operating state.

Mobile device-type locking

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.
