摘要:
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.

摘要:
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 allocating resources for individual radio connections at the interface between a transmitting device and a receiving device, especially the allocation of radio resources for a packet-switched radio connection. According to the invention a new TBF is created (306) e.g. when data transfer requires a change of communication parameters (305), and thus there are no pauses in the data transfer due to the release procedures of the existing TBF. The inventive solution saves network resources and facilitates providing simultaneously different services, such as transferring IP telephony and Mobility Management messages.
摘要:
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.

摘要:
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.

Data may be transferred on a packet radio network by creating a connection between two network entities. The data flow may contain active and passive periods. A connection may be maintained during a passive period for a predetermined amount of time or until further data becomes available for transfer.

A method as described by which an application executing in an application layer of a multi-layer communication protocol forming part of a general packet radio service (GPRS) session can signal for the setup and release of Temporary Block Flow (TBF) which will not be released during application execution in silent (inactive) periods. When applications such as voice, telnet or web browsing have specific traffic type data that have inactive periods between active periods are to be carried over GPRS, the session consists of multiple active periods. Current TBF release procedures lead to multiple TBF setups during such sessions. With the method described, a special type of TBF can be set up with special procedures for release of this TBF which greatly minimizes the need for multiple TBF setups during a session containing data transfers with inactive periods between active data transmissions.
摘要:
A method is presented for implementing a cell change for a mobile station (MS) in a packet-switched cellular radio system comprising a first base station (BTSold), a second base station (BTSnew) and a controlling unit (PCU, PCUold) controlling the operation of at least the first base station (BTSold). The method comprises the steps of establishing at the controlling unit (PCU, PCUold) the knowledge about the mobile station's (MS) need for performing a cell change from the cell of the first base station (BTSold) to the cell of the second base station BTSnew) while the mobile station (MS) is still communicating with the first base station (BTSold), transmitting from the controlling unit (PCU, PCUold) towards the mobile station through the first base station (BTSold) a first message (207, 309, 410) in order to fix an oncoming first moment of lime (209) as the moment of performing cell change and from said first moment of time onwards (209) providing access for the mobile station to the cell of the second base station.
