摘要:
Network discovery comprises discovering networks being available for a device and automatically providing communication settings for at least one of discovered networks to the device. The network discovery may be device initiated or network-initiated. The communication settings provision may be effected by network discovery functionality or another functionality such as device management functionality.

A mobile station executed method, wherein upon changing from a current cell to a new cell in a wireless packet data network the mobile station enters the new cell; generates a cell change packet data unit (PDU) message for informing the network of the location of the mobile station in the new cell; buffers the cell change PDU message into a PDU transmit queue before any buffered PDUs that were present before the mobile station entered the new cell; and transmits the buffered cell change PDU before any of the buffered PDUs that were present before the mobile station entered the new cell.

When a user of a mobile communication device is roaming in a visited network, an active network selection policy is formed of one or more partial policies. The partial policies typically include the network selection rules of the visited network, but may also include user home network rules, global network selection rules of the home network and/or further network selection rules of the home network. At least some of the partial policies, such as the network selection policy of the visited network, may be in accordance with Automatic Network Discovery and Selection Function (ANDSF) mechanisms.
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.

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.

A method for assigning sending permissions in a telecommunications system and a telecommunications system comprising a unit (20) providing access to said system for at least one telecommunication terminal (40) and a control unit (11) for scheduling data transfer between said at least one telecommunication terminal and the telecommunications system, whereby the control unit (11) is located apart from the access providing unit (20) and whereby said data transfer takes place on at least one transmission channel and more than one telecommunication terminal is arranged to use the same transmission channel so that a telecommunication terminal is allowed to send on the transmission channel when a sending permission is assigned to said telecommunication terminal, whereby the access providing unit (20) is arranged to assign a sending permission to the telecommunication terminal.
摘要:
The invention relates to arranging the transmission of packets between a mobile communication device and a mobile communication network. At least one temporary block flow is set up, and data is transmitted in packets in packet data traffic channels in a first direction from the mobile communication device to the mobile communication network. At the end of the transmission, information about the end of the block flow is set in the last packet, wherein the receiver of the packets acknowledges packet reception. After the end of the transmission of packets in said first direction, a determined time is waited until an acknowledgement is transmitted. If, while waiting, the mobile communication network detects a need for transmission of packets in the second direction from the mobile communication network to the mobile communication device, at least one packet data traffic channel is set up for data transmission in said second direction.
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.
