20080254804 | Scheduling of Mobile Terminals in a Mobile Communication System - The invention relates to a method for scheduling mobile terminals within a mobile communication network and to a base station performing this method. Further, the invention relates to a method for acting upon the reception of scheduling grants in a mobile communication system and to a mobile terminal performing this method. To allow the serving cell to control resource utilization for uplink transmissions of UEs in soft-handover, without thereby decreasing the system throughput of UEs in the serving cell which are not in soft-handover, the invention proposes to use control information transmitted via a shared absolute grant channel to the UEs along with an absolute grant, wherein the control information indicate whether the absolute grant is valid for mobile terminals in soft-handover only. | 10-16-2008 |
20080311923 | Fast Radio Bearer Establishment in a Mobile Communication System - The invention relates to methods for establishing a radio bearer between a network element terminating radio resource control protocol and a mobile terminal. The invention provides RNC for establishing a radio bearer between the RNC and a mobile terminal, especially adapted mobile terminals and a system comprising the network element and at least one mobile terminal. In order to reduce the delays implied by the signaling in the procedure the invention proposes two mechanisms. The first mechanism aims at reducing the delay implied by setting up the radio link for the radio bearer by preconfiguring a pool of resources comprising a set of at least radio bearer configuration and making the available radio bearer configurations known to the mobile terminals. The second mechanism aims at avoiding the delay implied by the explicit assignment of a radio network temporary identifier by signaling a set of available identifiers from which the mobile terminal may choose an identifier. | 12-18-2008 |
20090221293 | TRANSMISSION AND RECEPTION OF BROADCAST SYSTEM INFORMATION IN A MOBILE COMUNICATION SYSTEM - The present invention relates to a method and transmission apparatus for transmitting broadcast system information in a mobile communication system. Further, the invention relates to a method and mobile terminal receiving the broadcast system information. To provide an improved method for broadcasting broadcast system information the invention suggests mapping different partitions of broadcast system information to a shared transport channel or a broadcast transport channel for transmission. The mapping may take into account parameters inherent to the mobile terminals to which the broadcast system information is to be transmitted and/or parameters inherent to the different partitions of broadcast system information. | 09-03-2009 |
20090274086 | IMPROVED ACQUISITION OF SYSTEM INFORMATION OF ANOTHER CELL - Method for informing a mobile terminal (MN), which is located in a first cell, on system information of a second cell. In particular, pointers to the system information are transmitted from the base station of the first cell to the mobile node, while the mobile node is located in the first cell. The MN processes said pointer, comprising e.g. information on the transmission format and timing of system information in the second cell. Using an acquisition gap assigned by the network, the MN changes the frequency to the second frequency so as to acquire the system information based on the previously received scheduling information. Thus, the acquisition time for important system information may be reduced, as no Master Information Block on the second frequency has to be processed first, in order to acquire the system information. | 11-05-2009 |
20090280823 | EFFICIENT PAGING MECHANISM WITH SCALABLE BANDWIDTH ALLOCATION - The invention relates to an improved paging procedure for mobile nodes in a mobile communication system. A UE in idle mode is paged by a network entity via a selectable frequency subband of the system bandwidth. For every resource block, comprising part of the paging message or a diversity repetition thereof, a respective frequency subband is selected based on various parameters. These parameters may include: load in the subbands, UE capability in the tracking area and/or importance of paging information within the resource block. Furthermore, additional parity bits may be transmitted instead of the diversity repetition of the paging message, wherein the resource blocks, comprising the additional parity bits, are also transmitted via selectable frequency subbands. Thereby, the delay for changing from the idle to the active state of a mobile node may be reduced by increasing reliability of paging message transmission and resources may be utilized more efficiently. | 11-12-2009 |
20100022250 | TRANSMISSION AND RECEPTION OF SYSTEM INFORMATION UPON CHANGING CONNECTIVITY OR POINT OF ATTACHMENT IN A MOBILE COMMUNICATION SYSTEM - Method for informing a mobile terminal on target cell-specific system information to facilitate a mobility procedure such as handover or cell reselection in a mobile communication network. Further a radio resource control apparatus, a mobile terminal and a system comprising the radio resource control apparatus and the mobile terminal are provided. The invention suggests improvements to current mobility procedures so as to reduce the interruption time implied by the procedures. More specifically, it is proposed to include at least one pointer to target cell-specific system information to a control message, such as a handover indication or connection release message, pointing the mobile terminal to system information in the target cell relevant for system access and/or to perform mobility procedures. Further, a portion of the target cell-specific system information may also be comprised in the control message. | 01-28-2010 |
