A method for a GSM/EDGE node (), comprising establishing a TBF to another node and entering a transmit state in which data blocks are transmitted via said TBF to said other node. The transmit state is left if () there are no data blocks to transmit and positive ACK/NACKs have been received for transmitted data blocks, and, upon leaving said transmit state, a timer is started for the release of said TBF and a predefined TBF mode is entered in which the TBF is regarded () as released if the TBF release timer expires before data blocks are received by the network node to transmit to the other node, while, if data blocks are received by the network node to transmit to the receiving node, the predefined TBF mode is exited, the timer is stopped () and reset, and the first state is entered.

Temporary block flow release

A method for resolving a Temporary Block Flow (TBF) in a wireless network including one or more mobile stations exchanging data with a base station system. The method comprises receiving a RLC/MAC block and retrieving a first TFI in the RLC/MAC header. The TFI is compared to an assigned TFI. The capability for the associated MS to resolve TBFs based on extended TFI addressing is determined. If the received first TFI matches assigned TFI and represents a comprehensive TFI for the associated MS, the payload of the RLC/MAC block is decoded. When the first TFI matches assigned TFI value and is identified as a code point to an eTFI, at least a predetermined field of the RLC data block is decoded and an extended TFI, eTFI, is retrieved. The eTFI is compared with an assigned eTFI. Following a match, the payload of the RLC data block is decoded.

Method and arrangement for resolving a temporary block flow

A method of operating a mobile station requesting uplink access from a base station subsystem includes transmitting a first access request to a base station subsystem, and looking for an assignment message matching the first access request from the base station subsystem during a response interval after transmitting the first access request. When an assignment message is not received during the response interval, a second access request is transmitted to the base station subsystem after expiration of a retransmission interval after transmitting the first access request, with the retransmission interval being longer than the response interval.

Methods of transmitting access requests using reduced response intervals and related mobile stations and base station subsystems

A method is implemented in a mobile device for managing access to resources of a cellular communication system. The cellular communication system includes a plurality of base stations providing wireless access to the resources of the cellular communication system. The mobile device implements an enhanced extended access class barring (EEAB) process to minimize overloading of the resources of the cellular communication system.

Enhanced extended access class barring

A base station subsystem (BSS) and a method are described herein for improving an Access Grant Channel (AGCH) capacity when a downlink Temporary Block Flow (TBF) is established for at least one mobile station and used for sending the respective downlink payload. Plus, a mobile station (MS) and a method are described herein for improving the AGCH capacity when the mobile station is sent information required for establishing a downlink TBF on which it receives its respective downlink payload.

Optimized system access procedures

A Mobile Station, MS (), for a cellular communications network (), arranged to be camped on one of a plurality of k available Common Control Channels, CCCHs, in a cell () in the cellular communications network (), the MS () also being arranged to make successive attempts at uplink CCCH access until the MS () gains CCCH access. The MS () is arranged to make CCCH access attempt number i on CCCH number x, where x is in the range of 1 . . . k, with x determined by a function in the MS (). Also, a network node, (), for a cellular communications network, arranged to transmit System Information messages, to the MSs () in a cell, and arranged to insert an Information Element, an IE, in an SI message, which IE defines which CCCHs in the cell that an MS () may use for uplink CCCH access attempts.

Common control channel access

The invention relates to a method in a mobile network for resolving a Temporary Block Flow, a TBF, in a wireless network including one or more mobile stations exchanging data with a base station system. The packet data is transmitted by means of one or more RLC/MAC blocks each associated with the TBF. The TBF is identified by means of an Temporary Flow Identity, a TFI, and associated to an MS. The inventive method is applicable in a wireless communication system with an extended TFI addressing space. The method comprises steps of receiving a RLC/MAC block and retrieving a first TFI in the RLC/MAC header. The TFI is compared to an assigned TFI. The capability for the associated MS to resolve TBFs based on extended TFI addressing is determined. If the received first TFI matches assigned TFI and represents a comprehensive TFI for the associated MS, the payload of the RLC/MAC block is decoded. When the first TFI matches assigned TFI value and is identified as a code point to an eTFI, at least a predetermined field of the RLC data block is decoded and an extended TFI, eTFI, is retrieved. The eTFI is compared with an assigned eTFI. Following a match, the payload of the RLC data block is decoded. The procedure is repeated for further RLC/MAC block associated with the TBF until the TBF is resolved. The invention also relates to a mobile station and a base station system used to resolve a TBF according to the inventive method.

It is presented methods and apparatuses for uplink resource utilization in a telecommunication system. More particularly, embodiments disclosed herein relate to a method performed in a user equipment (), said user equipment () having data (D) ready to transmit, the data pertaining to a traffic class (i). The method comprises establishing a connection with a radio network node () and receiving threshold parameter sets (Th) from the radio network node (). Each threshold parameter set (Th) comprising at least a minimum size limit (S) associated with respective traffic class (i). The threshold parameter sets (Th) are used to determine if the amount of data that the user equipment () has ready to transmit is large enough to be transmitted or if it has been waiting long enough to be transmitted. If it is the UE () transmits the data to the radio network node (). There are also presented a corresponding method performed in the network node () and a user equipment () and a network node () for performing the methods.

Methods and apparatuses for uplink resource utilization in a telecommunications system

A wireless communication network having received priority access requests on an access channel issues an implicit reject response on a grant channel, such as a flag or other value embedded in an explicit access grant or explicit access reject response. The implicit reject response applies to some or all outstanding low-priority access requests. At the expiration of a terminal's grant channel monitoring window, if it has detected an applicable implicit reject response but not an explicit response, the terminal will refrain from transmitting another access request for a predetermined or configurable duration. The implicit reject response may comprise a flag, or a value that implicitly rejects only a fraction of the outstanding low-priority access requests. The implicit reject response may comprise a duration that the terminal must wait prior to transmitting another access request, and may direct the terminal to directly monitor the grant channel without transmitting a subsequent access request.
