Abstract:
A radiocommunication system supports high throughput rates over an air interface. An access network interface, e.g., between a base station and base station controller, conveys information between the base station and the rest of the terrestrial system. Techniques are provided to adjust transmission rates over the air interface based on loading of the access network. Techniques are also provided to control bandwidth allocation over the access network interface and distribute call blocking/delay percentages when there is an imbalance between the capacity of the air interface and the access network interface.

Abstract:
radio communications engineering. SUBSTANCE: process occurring in radio communication system is adapted to burst data transmission in compliance with FLOHA protocol of synchronized messages incorporating backup provision. Mobile stations of system are tailored to send access requests to base station during backup stage in mobile radio station which uses this protocol. Base station is tailored to receive access request from first mobile station and to execute it by sending channel backup message to it. Base station is tailored, in addition, to receive access request from at least second mobile station for which channel backup at the moment is impossible. According to proposed process, access request received from second mobile station is acknowledged in case channel backup cannot be executed by usual method. Acknowledgment is send in the form of access acknowledgment included in same channel backup message as that for first mobile station. In this way, access request is organized from each station of first group of mobile stations to base station in radio communication system congested at the time where there is no free channel for data transmission. EFFECT: enlarged functional capabilities. 7 cl, 2 dwg

Abstract:
In a multi-access environment, applications with high priority can temporarily, when needed, occupy parts or even complete resources from at least one of the accesses in a certain geographical area radio access can be secured for such applications. An area consisting of a number of cells is created In such an area, an application having high priority can have guaranteed resources on one pre-determined access while other "ordinary" traffic is temporarily directed to the other access(es) even if that may result in a lower Quality of Service (QoS) in that particular area.

Abstract:
cellular systems for burst data transmission. SUBSTANCE: automatic iteration request in cellular system for burst-data transmission to mobile objects using space-oriented redundancy protocol of ALOKHA system is made by assigning time identifying frame symbol to each data frame transmitted to or from mobile station. Assigned time-identifying frame symbol being used is the only one in location among sequences of frames transmitted at a time and can be assigned basing on information contained in data frame sent to mobile station or basing on information contained in channel redundancy message preceding data frame and sent to mobile station. Mentioned symbol can be also assigned basing on information contained in channel redundancy message preceding data frame sent from mobile station; symbol assigned is the only one in location among sequences of frames transmitted at a time. Time-identifying frame symbol is included in each block allotted to definite frame; automatic iteration request is just built around data block. Partial data frame is retransmitted in case of error in data transmission; this partial frame incorporates only blocks defined by type of automatic iteration request protocol being used such as selective or number reset one. Hence, primary block should not be entered for identifying mobile station. Blocks allotted to frames assigned to different mobile stations are compressed on downcoming link basing on time-identifying frame symbol. Mobile station introduces directive in random access request indicating that time-identifying frame symbol is already assigned. EFFECT: facilitated procedure. 20 cl, 6 dwg
Abstract:
A method and an apparatus for providing radio access bearer services for different applications in a network having a core network and a radio access network through radio access bearers between the networks are presented. One or more session traffic flows being sent by an application are identified, the identified session is characterized in the form of parameters needed for the determination of the one or more radio access bearers. The characterized parameters are converted into radio access bearer attributes. One or more radio access bearers defined by the attributes are requested and established. Each session is mapped onto a correct radio access bearer established upon receiving the request. The one or more radio access bearers are released when no longer needed.
