20120269145 | Method and Arrangement for Resolving a Temporary Block Flow - 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. | 10-25-2012 |
20130016602 | SIMPLIFIED SIGNALING FOR SMALL DATA TRANSMISSIONS - A signaling procedure for establishing and terminating connections for small data transmissions (SDTs) by wireless devices.

20140051443 | Methods and Apparatus for Enhancing Circuit-Switched Call Fallback (CSFB) Service for a Shared Network Node - Methods and apparatus enhance a circuit-switched call fallback (CSFB) service for a user equipment (UE) currently connected to a source cell in a serving radio access technology (RAT) communications network. Multiple different mobile network operators share a target CSFB cell selected for CSFB from one or more circuit-switched capable cells that supports circuit-switched services. Each mobile network operator is associated with a corresponding mobile network identifier. The UE transmits a first message requesting a CSFB service to a source cell radio network node serving the source cell. The source node, in response to the first message, sends a second message to the UE including preferred mobile network identifier information and a target CSFB cell identifier. The UE transmits a third message to a target cell node serving the target CSFB cell to trigger the establishment of a circuit-switched call connection for the UE in the target CSFB cell. The target cell radio network node receives the third message, which includes preferred mobile network information to permit the target node to direct the third message to a core network node operated by one of the mobile network operators identifiable based on the preferred mobile network information. That core network node then initiates the requested CSFB service for the UE. Based on the preferred mobile network identifier information, the UE determines whether a location area update procedure must be performed in the target CSFB cell, and if so, transmits a fourth message to trigger the location area update procedure prior to triggering the establishment of a circuit-switched call connection. | 02-20-2014 |

20140146671 | IMPLICIT REJECT RESPONSE - 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.

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. | 05-29-2014 |
