20080200173 | Method and arrangement for controlling cell change and a terminal of a cellular system - The invention relates to an improved method and arrangement for controlling a cell change performed by a terminal of a cellular radio system. In particular the invention relates to a cell change in a situation where the terminal is connected to a special service provided by its current cell, e.g. to the GPRS service (General Packet Radio Service). An essential idea of the invention is that in conjunction with a cell change order a base station sends to the terminal information about whether the terminal is allowed not to carry out the cell change order if the terminal does not know the timing information of the new cell assigned to it. This information is advantageously sent in a signalling message of a certain service, such as the GPRS service. It is an advantage of the invention that a terminal connected to a certain service will not make unnecessary cell change attempts which are doomed to fail. The invention helps direct the cell change in such a manner that the load caused by possible repeated cell change attempts on the terminal and radio signalling is low. | 08-21-2008 |

A local database that indicates measurement report status of the plurality of user equipments is dynamically updated based on the received measurement reports, and a request for a next measurement report is restricted to a limited number of the UEs based on the updated measurement report status. In various embodiments, the measurement report status indicates battery status for each of the UEs, the request includes a parameter by which the UEs generate a number and compare against to determine if they should report, and the UEs determine based on the parameter and a metric of their own battery status. Apparatus, method and computer programs are detailed for both the network side and the UE side of an overall system. | 08-28-2008 |

The indication can be implicit in the position of the particular resource allocation within the plurality of resource allocations as arranged during the connection setup, or it may be explicit with the resource allocation such as from a bit stolen from the CRC field. The persistent allocation can be terminated in multiple ways, including overwriting with a new persistent allocation, sending an end bit or no data, or sending an improper CRC field which is arranged by an absence of both a NACK from the UE and a re-transmission from the network as a terminating condition. | 09-25-2008 |

The context identifier may be a random number, a C-RNTI, an eNB-ID, or a token.
