The invention relates to a method of limiting the size of synchronization messages between a first synchronization device and a second synchronization device. The first device specifies a maximum message size for synchronization messages to be sent to the first device and transmits information on the maximum message size to the second device. The second device transmits to the first device one or more synchronization messages which are equal to or smaller than the maximum message size of the first device.

Data synchronization

A method of arranging synchronization of databases, the method comprising the steps of establishing a transport layer connection for synchronization between a first and a second device which synchronize databases. During initialization of synchronization a first update identifier, which is stored at least in the first device and describes the latest synchronization event the devices have performed in the databases, and a second update identifier, which is defined by the first device and describes the present synchronization, are transmitted from the first device to the second device. The second update identifier is stored in the first and the second device. The contents of the first update identifiers stored in the devices are updated in the first and the second device if synchronization has been performed and after this said transport layer connection has been ended substantially properly.

Synchronization of database data

A method for arranging a packet radio service in a wireless telecommunication system comprising at least one mobile station. The method comprises activating in the mobile station at least one packet data context for packet-switched data transmission of an application in the mobile station. In the mobile station, a busy condition is automatically set for the packet data context for suspension situations. When the packet data context in the mobile station is requested to be suspended, the packet data context is prevented from being suspended in response to the packet data context suspension request being received from outside the application.
