TERMINATING CALL HANDLING FOR POWER SAVING ACTIVATED USER EQUIPMENT
The embodiments herein relate to terminating call handling for power saving activated user equipment. In one embodiment, there proposes a method in a IP Multimedia Subsystem Application Server, IMS-AS, for handling a terminating call for a User Equipment, UE, using power saving functionality, comprising: obtaining power saving information of the UE; handling the terminating call based on the power saving information. With the embodiments, the time and network resource for the terminating call can be saved and the user's experience can be enhanced.
DISCONTINUOUS RECEPTION (DRX) ENHANCEMENTS IN LTE SYSTEMS
Embodiments of a system and method for providing DRX enhancements in LTE systems are generally described herein. In some embodiments, a system control module is provided for controlling communications via a communications interface. A processor is coupled to the system control module and is arranged to implement an inactivity timer and an on-duration timer for determining an active time for monitoring subframes on the physical downlink control channel for control signals, the processor further monitoring subframes after the active time.
System for managing electrical consumption in an appliance
Some appliances, normally supplied by a mains supply, also comprise an emergency supply by batteries able to take over from the mains supply. The batteries used by the emergency supply are generally protected by a fuse. These appliances are liable to consume greater than what could be supplied by the batteries of the emergency supply. When there is a break in the mains electrical supply, it is then preferable to limit the current consumed by the appliance in order not to damage the fuse protecting said batteries. However, the fuses are hardware modules having a reaction time of a few hundreds of milliseconds. If it is wished not to damage the fuse, it is therefore essential to reduce the current consumption of the appliance within a time less than the reaction time of the fuse. The invention relates to a system and method for instantaneously reducing the electrical consumption of an appliance in the event of a break in the mains supply.
Wakeup system and method for devices in power saving mode
A computer device may include a memory storing instructions and a processor configured to execute the instructions to select a broadcast method for a wakeup signal for a wireless communication device; instruct a base station to broadcast the wakeup signal using the selected broadcast method; and provide information identifying the selected broadcast method to the wireless communication device. The processor may be further configured to receiving a wakeup request from a machine-type communication interworking function (MTC-IWF) device; map the received wakeup request to a wakeup signature beacon signal associated with the wireless communication device; and instruct the base station to transmit a wakeup signature beacon signal to the wireless communication device based on the received wakeup request.
COMMUNICATION APPARATUS, CONTROL METHOD OF COMMUNICATION APPARATUS, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM
A communication apparatus receives a radio frame complying with an IEEE802.11 series standard, acquires information of a WUR (Wake-up Radio) Discovery element included in the received frame, and decides, based on the information of the WUR Discovery element, a WUR channel used to wait for a WUR Discovery frame.
Key Derivation for a Module Using an Embedded Universal Integrated Circuit Card
A module with an embedded universal integrated circuit card (eUICC) can include a received eUICC profile and a set of cryptographic algorithms. The received eUICC profile can include an initial shared secret key for authentication with a wireless network. The module can receive a key K network token and send a key K module token to the wireless network. The module can use the key K network token, a derived module private key, and a key derivation function to derive a secret shared network key K that supports communication with the wireless network. The wireless network can use the received key K module token, a network private key, and the key derivation function in order to derive the same secret shared network key K derived by the module. The module and the wireless network can subsequently use the mutually derived key K to communicate using traditional wireless network standards.
User Equipment Operating Mode Control
A notification regarding a transition of a User Equipment (UE) from a standby operating mode to an active operating mode is exchanged between a UE and a network element in a communication network. The notification could be an uplink notification that is transmitted by the UE to the network element in response to an operating mode transition criterion for the UE being met at the UE, or a downlink notification that is transmitted by the network element to the UE in response to an operating mode transition criterion for the UE being met at the network element. The UE transitions from the standby operating mode to the active operating mode in response to the operating mode transition criterion being satisfied. The transmitter of the notification, which could be the UE or the network element, could also perform grant-free transmission of data without first receiving a response to the notification.
STAGGERED EXTENDED SLEEP CYCLES, COMPRISING ON AND OFF SLEEP DURATIONS, IN WIRELESS DEVICES
Extended sleep in a wireless device. In an embodiment, synchronized parameters, used by a wireless device to define an extended-sleep cycle, are stored at a system. Based on the synchronized parameters, the system determines a transmission time at which to transmit a message over the wireless communication network such that the message will be received by the wireless device during a portion of the extended-sleep cycle during which the wireless device is monitoring paging occasions. The message is then queued until it is transmitted at the transmission time.
Communications device and method
A communications device establishes a communications context for communicating data packets using a packet communications bearer from the communications device via mobile communications network in a connected state and releases communications context when in an idle state. A controller is configured in combination with a receiver to receive signalling information providing an indication of one or more functions performed by at least one of the receiver, a transmitter, or the controller which can be changed in a power saving state, and when in either the idle state or the connected state, to enter the power saving state in which the one or more of the operations performed by at least one of the receiver, the transmitter, or the controller are changed in accordance with the indication of the changed functions received in the signalling information from the mobile communications network.
Set of Servers for "Machine-to-Machine" Communications Using Public Key Infrastructure
A set of servers can support secure and efficient Machine to Machine communications using an application interface and a module controller. The set of servers can record data for a plurality of modules in a shared module database. The set of servers can (i) access the Internet to communicate with a module using a module identity, (i) receive server instructions, and (iii) send module instructions. Data can be encrypted and decrypted using a set of cryptographic algorithms and a set of cryptographic parameters. The set of servers can (i) receive a module public key with a module identity, (ii) authenticate the module public key, and (iii) receive a subsequent series of module public keys derived by the module with a module identity. The application interface can use a first server private key and the module controller can use a second server private key.
