Abstract: A method and an apparatus are described for increasing the flexibility of uplink resource allocation for a mobile station (MS) (100), that is backwards compatible with earlier standards that provide only a single data flow per MS. The method includes steps of (A) associating an allocated uplink resource (an Uplink State Flag (USF)) with one or more Temporary Block Flows (TBFs) for a Packet Data Channel (PDCH), and not with a MS per se (although a given USF is associated with only a single MS); and (B) using a Temporary Flow Identity (TFI) for identifying a TBF, where a TFI may be unique to a PDCH and, if not, is unique with respect to the MS on a PDCH (and hence with respect to the USF). The result is that the MS is enabled to send any of its TBFs on allocated resources of the same PDCH. An uplink resource may be allocated to the MS dynamically using the Uplink State Flag (USF) or by using a fixed allocation. A total of n Radio Bearers are associated with a single TBF, where n?1.

Abstract: In the LAPDm a short message service is implemented by pre-emption of every second signalling message when there is a short message to be sent. Same pre-emption mechanism is also needed when the RLC/MAC protocol is used on the data link layer instead of the LAPDm. The mechanism is provided by defining at least two different identities to be used with frames transmitted on the signalling channel; and pre-empting frames on the MAC at least on the basis of the identity relating to a frame. The identities are preferably identified on the basis of the signalling radio bearer of the frame.

Abstract: The invention relates to allocating memory resources for packet data transfer on a layer 2 link in an acknowledged mode over an air interface between a mobile station and a network. In order to allow dynamic use of existing resources, a common memory is defined to be shared by at least two parallel layer 2 links and memory is allocated for each parallel layer 2 link from the common memory.

Abstract: The invention relates generally to a method and an arrangement for transferring information in a packet radio service. The invention further concerns the technology of transferring control information relating to packet data transfer resources on individual packet-switched radio connections at the interface between a transmitting device and a receiving device. It s an objective of this invention to provide a method and a system that offers solutions to the prior art problems. Especially, it is an object of this invention to provide a solution for signalling, which enables the use of more than one connection (TBF) and time slot for packet data transfer in one data transfer direction, and the use of asymmetric resources for uplink/downlink data transfer. The objectives of the invention are fulfilled by providing a procedure, in which the one and same uplink control channel is used for transferring uplink control information, which relates to at least two downlink TBFs.

Abstract: A method for operating a wireless communications system includes a step of signalling, between a mobile station to a network, that the mobile station or the network is temporarily ceasing transmission of circuit switched information (DTX), which could be voice frames or data frames. For the case of voice, the method further includes a step, executed in the network, of determining if a current uplink or downlink voice traffic channel that is assigned to the mobile station can be retained by the mobile station, or whether the current uplink or downlink voice traffic channel must be released by the mobile station. Only if it is determined that the current uplink or downlink voice traffic channel must be released by the mobile station, does the network signal to the mobile station to release the channel.

Abstract: A method and an apparatus are described for sending packet data over a wireless link. The method includes sequentially multiplexing a plurality of radio bearers onto one Temporary Block Flow (TBF) by performing, for a first radio bearer, transmitting the first radio bearer identity to a receiver in at least one first Radio Link Control (RLC) block of a Temporary Block Flow (TBF); upon an occurrence of a change from the first radio bearer to a second radio bearer, transmitting the second radio bearer identity to the receiver in at least one subsequent Radio Link Control (RLC) block of the same TBF; and, at the receiver, sequentially demultiplexing the plurality of radio bearers from the one Temporary Block Flow (TBF) by first detecting the presence of the radio bearer identities in received RLC blocks.

Abstract: The invention relates to methods for providing parameter values required at different locations of a cellular communications system for packet header creation, to cellular communications systems and to their components. In order to enable a supply of continuous values for said parameters after a change of access of a user equipment from one network element to another, it is proposed that the parameter is either continuously stored and/or generated in the user equipment throughout a connection or transmitted from a first network element to the user equipment when the access of the user equipment is changed from the first to a second network element. On the other hand, it is proposed that the user equipment transmits said parameter to a network element to which it changes or that the network element to which the user equipment was connected transmits said parameter to the network element to which the user equipment changes.

Abstract: Apparatus, and an associated method, facilitates changeover of mode of operation of a mobile station operable in a cellular communication system. Changeover of the mode of operation of the mobile station is required when the mobile station is operated in the packet mode and a circuit-switched call is to be terminated at the mobile station. A page is transmitted to the mobile station which includes an allocation of time during which a response to a page forming a request to suspend the packet mode of operation is to be generated.

Abstract: For transmitting information about the neighbouring cells to mobile stations, a base station of a cellular radio system creates a message (27, 27′) containing information about the neighbouring cells and transmits it to the mobile station. In addition to the transmission frequencies used in the neighbouring cells, the base station includes in the message other information characterizing the neighbouring cells (32a, 32b, 32c, 34). In particular, the base station includes in the message information about the quality of service offered to mobile stations by each of the neighbouring cells mentioned in the message. On the basis of the message, the mobile station makes a preliminary selection of a group of the most advantageous new cells and performs measurements among this preliminary selection in order to find a suitable new cell (41, 47). If the measurements show that there is at least one suitable new cell among the preliminary selection, the mobile station selects a new cell from this group (42).

Abstract: A method of operating a mobile telephone within a geographical area having overlapping coverage from a first, GSM, network and a second, UMTS, network, where said GSM network is the home network (HPLMN) of the mobile communication device and said GSM and UMTS networks provide respective first and second sets of services in said geographical area. The method comprises registering the telephone with the GSM network when a service of said first set is requested and registering the device with the UMTS network when a service of said second set, but not of said first set, is requested. The method provides the mobile telephone with a roaming for service function.

Abstract: Cellular radio system base stations (10, 12) offer various service levels and transmit control messages (14) indicating said service levels. Terminals (20) store information (22) about previous connections and, based on that information or on their own capability, produce a prediction on the service level required by the next connection. A terminal selects a cell such that the service level in the cell matches the terminal's prediction on the service level required.
