SELECTED ESTABLISHMENT OF UNIDIRECTIONAL CHANNEL IN EXTENDED UNIVERSAL TERRESTRIAL RADIO ACCESS (E-UTRA) AND EXTENDED PACKET SYSTEM (EPS)

摘要

FIELD: information technologies.;SUBSTANCE: basic network object in a wireless network may send a request to an access point to establish a unidirectional channel, which contains a list of unidirectional channels for their establishment with a joined mobile device. The request to establish a unidirectional channel comprising a list of unidirectional channels includes separate messages of a level, which is not related with access provision (NAS), corresponding to each unidirectional channel in the list. Separate NAS messages may be related to each record about a unidirectional channel in the list. The access point may accept the list and try to initialise one or more unidirectional radio channels in the list. Since NAS messages separately correspond to the specified unidirectional channel, the access point may forward NAS messages to a mobile device only for unidirectional channels, which are initialised successfully, letting for their selective establishment. Besides, the access point may provide to the basic network a condition of initialisation for individual unidirectional channels.;EFFECT: reduced time costs for successful tuning of requested unidirectional channels by a basic station for a mobile device.;50 cl, 15 dwg
