Abstract:
A method for choosing channel coding and/or interleaving scheme is applied in a communication connection over a radio interface between a terminal and a base station of a cellular packet radio system. A certain decision-making device allocates channel coding and/or interleaving schemes to communication connections. A request message is communicated (to the decision-making device, indicating a certain set of Quality of Service parameters associated with a certain first communication connection. The set of Quality of Service parameters is mapped to a certain first channel coding and/or interleaving scheme as a part of the channel coding and/or interleaving scheme allocation made by the decision-making device. The first channel coding and/or interleaving scheme is communicated to the base station and the terminal for them to apply said first channel coding and/or interleaving scheme in the first communication connection.
Abstract:
The invention provides a method of handing over user equipment from a source cell to a target cell in a cellular communications network. The cellular communications system comprises a plurality of control units. The method comprises the steps of receiving a message indicating if the operation of the radio link control protocol is to be continued or reset when changing cell, resetting the operation of the radio link control protocol if the message indicates that the current radio link control protocol is to be reset, or continuing the operation of said radio link control protocol if the message indicates that the radio link control protocol is to be continued.
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:
A packet-switched handover from a first cell to a second cell in a cellular network is discussed. Packet-switched services are provided for a mobile station in the first cell based on a set of information relating to provision of packet-switched services and a protocol for handling provision of packet-switched services for mobile stations, said protocol being a protocol between a cell and a respective control network element. In a control network element relating to the first cell a first message is received, which indicates a request for a packet-switched handover for a mobile station. In response to said first message, a second message is sent to the second cell. This second message requests creation of a set of information relating to provision of packet-switched services for the mobile station in the second cell, and the second message belongs to said protocol for handling provision of packet-switched services for mobile stations.
Abstract:
The invention relates to a method and an arrangement for indicating requirements for broadcast and multicast service reception. A basic method comprises a step of transmitting a message indicating the requirements over the air interface to terminals within the service range. An alternative method comprises a step of informing the terminal's capabilities to the system which deduces on the basis of informed data whether the terminal is capable of joining the service or not. A wireless system comprising a network element and at least one wireless terminal operable in the system is presented. The wireless terminal is capable of receiving the broadcast message indicating the requirements and sending a capability notification. The network element is capable of receiving the notification and sending the message indicating the requirements. Service requirements and corresponding terminal capabilities are divided into a number of capability classes which can be announced instead of explicit data.
Abstract:
The invention relates generally to a method and an arrangement for transferring information in a packet radio service. Especially the invention applies to transferring delay sensitive data, such as speech and video data, in a mobile cellular telecommunications system. It is an object of this invention to provide a solution, in which the physical connection of a packet radio service is kept reserved also during the passive periods of a session but the same physical resource can still be shared between multiple users. In the present solution after the end of an active period of data transmission a predetermined time period is waited until the connection is released. The length of the time period is informed to the mobile station by the network on a dedicated or on a broadcast channel. The length of the time period is preferably made dependent on the required quality of service value of the connection and on the momentary communication activity in the network or cell.

Abstract:
A method and an arrangement for transferring information including delay sensitive data, such as speech and video data, in a packet radio service is provided. Data blocks are transmitted from a mobile station to a radio resource entity during a first active data transfer period using an uplink temporary block flow (TBF) connection. The uplink TBF connection is maintained during a passive period that follows the first active data transfer period, wherein during the passive period the mobile station does not send data blocks to the radio resource entity.
