In one non-limiting aspect thereof the exemplary embodiments of this invention provide a method, a computer program product and a mobile station operable in accordance therewith to originate a request at the mobile station to terminate reception of a Multimedia Broadcast/Multimedia Service radio bearer; and to transmit the request to a wireless network that is the source of the Multimedia Broadcast/Multimedia Service radio bearer. In another non-limiting aspect thereof the exemplary embodiments of this invention provide a method, a computer program product and a wireless network node operable in accordance therewith to receive a request from a mobile station to terminate reception of a Multimedia Broadcast/Multimedia Service radio bearer and, in response, to send the mobile station a PACKET TBF RELEASE message that includes an identification of the mobile station and a TBF_RELEASE_CAUSE value defined as Stop Receiving MBMS Radio Bearer.

Method, apparatus and computer program for terminating mobile station receipt of multimedia broadcast/multimedia service (MBMS) service bearer

A method for performing cell re-selection in a cellular network includes a subscriber terminal measuring received powers of neighbour cells in accordance with system information received from a current cell, selecting one of the neighbour cells as a new cell, the subscriber terminal receiving a part of the system information sent by the new cell, calculating the time used for receiving the system information of the new cell by employing the length information in the system information part sent by the new cell, and deciding whether to continue the re-selection of said new cell on the basis of the calculated time.

Cell re-selection utilizing system information length

A system, apparatus, computer program product, and method for controlling output power levels of over-the-air (OTA) transmission signals from a terminal operable on a network. At least one parameter used by the terminal in establishing its proper RF output power level is provided by the network in a channel assignment message(s). The terminal can then define the proper output power level in changing circumstances, such as where the common broadcast channel is mapped on a different band than traffic channels, in connection with handover or DTM operations, etc. Further, the parameter is provided via the channel assignment message(s) in connection with DTM operation after handover, where the common broadcast channel is mapped on the same frequency band as the traffic channel. When the proper output power level has been defined using the parameter received from the channel assignment message, the terminal can communicate information to the network using the proper output power level.

A method for performing cell re-selection in a cellular network includes a subscriber terminal measuring received powers of neighbor cells in accordance with system information received from a current cell, selecting one of the neighbor cells as a new cell, the subscriber terminal receiving a part of the system information sent by the new cell, calculating the time used for receiving the system information of the new cell by employing the length information in the system information part sent by the new cell, and deciding whether to continue the re-selection of said new cell on the basis of the calculated time.

The invention relates to a method for performing cell re-selection in a cellular network, and a subscriber terminal and a network part using the method. In the method: () the subscriber terminal measures received powers of neighbour cells in accordance with system information received from a current cell; () one of the neighbour cells is selected as a new cell; () the subscriber terminal receives a part of the system information sent by the new cell; () the time it takes to receive the system information of the new cell is calculated using length information in a system information part sent by the new cell.

A method and arrangement is provided for controlling cell reselection by a terminal of a cellular radio system, in particular where the terminal is connected to a special service, such as a General Packet Radio Service. A base station transmits information to the terminal about whether the terminal may try cell reselection when required. This information is transmitted in the signaling message of a certain service, such as the GPRS service. A terminal connected to the certain service obtains information about whether it may directly change the serving base station to another base station offering a corresponding service, without temporarily accessing the signaling function of a lower level system. Cell reselection is facilitated such that loading on the terminal and on radio signaling is as low as possible.

Method and arrangement for managing cell reselection in a terminal for a cellular system

The invention pertains to an improved method and arrangement for cell selection performed by a mobile station in a cellular radio system. Particularly the invention pertains to cell selection in a situation where the mobile station is connected to a special service such as the GPRS (General Packet Radio Service) offered by the current cell. An essential idea of the invention is that a base station sends to the mobile station information about whether the base station of a neighbouring cell offers the same service. This information is sent preferably in a signalling message of a certain service, such as the PSI message of the GPRS system ( ) or in a system information SI message of a lower-level service, e.g. in a SI message. The mobile station changes serving base stations directly, without having to use lower-level system signalling ( ) in between. The invention helps adjust cell reselection such that the load on the mobile station and radio signalling, caused by measurement of possible new cells and by message traffic, is as small as possible.
