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 method of interpreting an authorization token is described herein. The service can receive an authorization token from a client device, and validate a signature of the authorization token. The service can identify an allowed function value associated at least part of an entitlement representation contained in a body of the authorization token. The service can convert the allowed function value to an allowed function bitmask that includes bits at a plurality of bit positions that are set to values indicating whether the subscriber element has attributes associated with each of the plurality of bit positions on a predefined attribute list. The service can determine whether the allowed function bitmask indicates that the subscriber element has one or more qualifying attributes that entitle a user of the client device to access the service.

The present invention is related to a wireless transmit/receive unit (WTRU) for providing advanced security functions. The WTRU includes trusted platform module (TPM) for performing trusted computing operations; and a secure time component (STC) for providing a secure measurement of a current time. The STC and the TPM are integrated to provide accurate trusted time information to internal and external to the WTRU. The STC may be located on an expanded a subscriber identity module (SIM), on the WTRU platform, or two STCs may be used, one in each location. Similarly, the TPM may be located on an expanded SIM, on the WTRU platform, or two TPMs may be used, one in each location. Preferably, the STC will include a real time clock (RTC); a tamper detection and power failure unit; and a time report and sync controller.

A method for facilitating collection and display of information related to data usage by a plurality of mobile devices is disclosed. The method involves receiving first quantity information and sending a first identifier associated with the plurality of mobile devices and first activity-related information including the first quantity information to a server. The method also involves receiving group activity-related information associated with the plurality of mobile devices, the group activity-related information derived at least in part from second activity-related information including second quantity information, and producing signals for causing a display to display information derived from the group activity-related information. A method of associating a plurality of mobile devices in a group is also disclosed. Systems and computer-readable media for facilitating collection and display of information related to data usage by a plurality of mobile devices and for associating a plurality of mobile devices in a group are also disclosed.

Telecommunication services systems and methods are disclosed. The telecommunication services systems and methods preferably enable a buyer to certify and activate a used wireless telecommunications device. The systems and methods may also be employed to provide the buyer with specialized pricing options and other customized services.

The present invention discloses methods and systems for communicating at a cellular router between a first wireless communication module and a first subscriber identity module (SIM). The cellular router receives a first request from a first wireless communication module and encapsulates the first request in a first modified request. The cellular router then sends the first modified request to a first SIM card in a first communication apparatus and waits for a first modified reply. While waiting for the first modified reply the cellular router sends at least one halt message to the first wireless communication module after a first time threshold. After receiving the first modified reply, the cellular router decapsulates the first modified reply to retrieve a first reply and sends the first reply to the first wireless communication module where the first modified reply is a reply to the first.

Briefly, in accordance with one or more embodiments, for example, a method and/or system is provided to at least authenticate a mobile subscriber that has been registered via a registration process comprising. A current international mobile subscriber identifier (IMSI) associated with a mobile telephone number received electronically via a network is queried. A database entry created via the registration process including an IMSI associated with a received mobile telephone number at the time of mobile subscriber registration is also queried. At least the current IMSI and the IMSI of the database entry are compared. Account status of the mobile subscriber based at least in part on a match between the current IMSI and the IMSI of the database entry is verified. Verifying the account status includes determining creditworthiness with respect to the account of the mobile subscriber.

A VoWiFi registration control method and apparatus, an electronic device, and a server, are provided. A method on an electronic device side includes: obtaining first feature information of an electronic device; and controlling, in a case that the first feature information does not match second feature information, termination of VoWiFi registration in a process of performing VoWiFi registration. The first feature information is position feature information determined based on a first position of the electronic device, and the second feature information is position feature information determined based on a second position of the electronic device.

This Application sets forth techniques for provisioning and activating electronic subscriber identity modules (eSIMs) for mobile wireless devices. An eSIM is reserved during a sales order process and later activated during device activation after receipt by a user. An option for eSIM installation in place of (or in addition to) physical SIM installation is provided when purchasing the mobile wireless device. The reserved eSIM can replace a previous SIM/eSIM or be a new eSIM. During device activation, installation and activation of the eSIM occurs. Activation of the eSIM can occur before or after deactivation of a transferred SIM/eSIM. The mobile wireless device accounts for propagation delay of eSIM activation through MNO servers by disabling and re-enabling the eSIM until initial attachment to an MNO cellular wireless network succeeds or a maximum number of retry attempts is reached.
