Control system with predicted response time of field device via wireless network. RU patent 2447493.

FIELD: information technology.

SUBSTANCE: host computer communicates with field devices by means of sending control messages and receiving response messages via wireless network. When host computer sends control message via wireless network the host computer is given predicted response time within which a field device receiving the message should respond. Wireless network cycles between wait status and active status based on wireless network "current source connected/current source disconnected" cycle. Predicted response time is based on current status of wireless network, "current source connected/current source disconnected" cycle, and time of field device on, execution of action (like parameter measurement) and output of response messages.

EFFECT: providing possibility to determine if there was breakdown in connection with one of field devices when communicating via wireless network.

Protected processing of client system mandate for access to web-resources / 2447490
In this method, client computer system sends the first request for Web-based access to recourse, then it is forwarded to registration page providing interface for accepting user mandates. Client computer system which uses registration page to present user mandates to sever computer system receives encrypted data that represents part of user mandates and time-dependent signature. The mentioned signature has been obtained from part of user mandates time-dependent signature key. Encrypted data has been coded using time-dependent encryption key, and time-dependent signature key as well as time-dependent encryption key has been obtained from the key stored in memory of cyclically changed keys. In this process, client computer system sends the second request for Web-based access to resource that includes encrypted data.

Extended uplink for inactive state in wireless communication system / 2446637
Method is suggested to support work with extended uplink in inactive state. User equipment (UE) can send access preamble for arbitrary access being in inactive state, and can acquire message including resources distributed for UE. Distributed resources can be selected by Node B from pool of resources which can be predistributed to Node B extended uplink. UE can send information (e.g. planning information and/or its own identifier UE) to Node B c using distributed resources. UE can accept acknowledgment addressed to UE based on UE identifier. UE can remain in inactive state and continue to use distributed resources until they are released. Alternatively, UE can change from inactive state to active state and either continue to use distributed resources or accept distribution of new resources for active state.

Requests of uplink / 2446636
Systems and techniques are described which simplify generation of uplink requests which are responsible for bitrate of multiple unidirectional radio channels. In particular, priorities are assigned to one or more unidirectional radio channels served by user equipment. Additionally, each unidirectional radio channel is assigned a priority bitrate and maximum bitrate. Prioritised bitrates and maximum bitrates of at least one unidirectional channel are used to determine size of high priority queue and size of full queue. Sizes of queues are included in uplink resource request transferred to access point.

Wireless communication system / 2446635
Terminal measures wireless channel quality for each frequency band and notify base station about quality; base station determines frequency band to be used by terminal based on terminal notification. Then the terminal is grouped depending on difference and so on in frequency band in which the terminal is working, and notified to which terminal group it belongs; upon receiving notification from base station the terminal establishes its own and terminal group available frequency band and measures notified value of channel quality of available frequency band; measurement result is reported to the base station; the base station performs planning process for each available frequency band based on wireless channel quality of available frequency band of terminal and starts communicating with the terminal.
