A method and system of detecting a delinquent mobile user device. An international mobile subscriber identity (IMSI) of a subscriber identity module (SIM) card of the user device is determined by the user device. The IMSI is sent to a Remote Recovery Server (RRS). A message is received from the RRS as to whether the IMSI is authorized for the user device. Upon determining that the IMSI is not authorized for the user device, a notification is displayed on a display of the user device.

A network access control method includes obtaining network information of an electronic device, determining, using the network information, whether the electronic device needs to use a first access point name (APN) network channel, and generating a network channel switching instruction in response to determining that the electronic device needs to use the first APN network channel. The network channel switching instruction instructs to switch the electronic device from a second APN network channel to the first APN network channel. The second APN network channel has access to more network resource addresses than the first APN network channel.

The present system relates to a server providing data connectivity to an electronic device. The server includes a memory storing data connectivity policy information for the electronic device. The policy information defines a data traffic threshold marking a change in data traffic billing for data traffic the electronic device may exchange with service provider(s) over a telecommunication network. The server has a receiver, which monitors data traffic from instances of applications installed on the electronic device, and has a usage monitor, which maintains a first quantity indicative of the monitored data traffic. A data connectivity policy manager detects that the first quantity exceeds the data traffic threshold of the data connectivity policy, determines a first application requesting such traffic, retrieves a second application linked to the first application, the second application having data traffic billing specific to the second application, and presents the second application to the electronic device.

Telecommunications data usage management may be provided. A network state associated with a communication network may be identified. Upon determining that the network state is not in compliance with a data usage policy, access to the communication network may be restricted for at least one application.

Methods and apparatus for managing quality of service for video streaming, in which a Policy and Charging Rules Function (PCRF) in a Policy Charging Control (PCC) architecture of a telecommunications system receives from a Policy Control Enforcement Function (PCEF) a notification indicating that a video service has started for streaming video content to a user equipment (UE). A first Quality of Service (QoS) setting for streaming the video service to the UE is determined. First QoS setting data identifying the first QoS setting is transmitted to the PCEF. The PCEF transmits a further notification to the PCRF indicating that a particular stage has been reached. The PCRF receives the notification from the PCEF. In response to the further notification, a second QoS setting specifying a lower QoS than the first QoS setting for streaming the video service after the particular stage is determined. The PCRF identifies the second QoS setting to the PCEF.

System and methods are disclosed that improve the speed, efficiency and usefulness of providing telecommunication service by computerized telecommunication service. In some embodiments, systems and methods described herein enable a user to receive the telecommunication service to a mobile device of the user, such as by adding data service, minutes and/or text messages to the prepaid plan, in response to having an advertisement played on or otherwise delivered via the mobile device. An ad may be displayed or otherwise played on the mobile device or inserted into messages sent by the user via the mobile device for the user to received minutes, data or texts added to their prepaid plan. The service carrier may split compensation received from an advertiser for playing an ad on a customer's device between the service carrier and the customer.

A method for improving the reliability of a security system includes determining an amount of cellular communication data usage over a cellular communication connection since the beginning of a predefined period of time and a remaining amount of cellular communication data for the remainder of the predefined period of time based at least in part on the amount of cellular communication data usage over the cellular communication connection since the beginning of the predefined period of time and a predefined cellular data usage cap for the predefined period of time. When a determination is made that a projected amount of cellular communication data usage is expected to exceed the predefined cellular data usage cap at or before the end of the predefined period of time, one or more operations of the security system are changed to reduce the amount of cellular communication data usage by the security system.

Dynamic adjustment of consumption limits governing the consumption of credit units from a “provider account” (24) offers numerous advantages in the context of Online Charging (OC), both to the involved communication network operator(s) and to the users or applications associated with the UEs (12) that use communication services subject to credit availability in the provider account (24). Specifically, two or more “consumer” accounts (26), each associated with one or more UEs (12), consume credit units from the provider account (24), for authorizing communication-usage by the associated UE(s) (12), subject to a respective consumption limit, which may be regarded as defining an allocated share of the credit units in the provider account (24), for use by the consumer account (26). Adjusting the consumption limits one or more times during the validity period of the credit units offers the opportunity to rebalance the credit allocations, such as in view of aggregate rates or amounts of consumption or consumption imbalances.
