The invention relates to a method and an arrangement for supporting TCP/IP services in a cellular radio access network connected to a telecommunications network offering TCP/IP services. In accordance with the invention, the bearer service parameters required by different TCP/IP services are predetermined in the radio access network, the correct parameters for a given connection being selected by identifying the TCP/IP service on the basis of the content of the first IP packet received. Thus, different TCP/IP services can be handled in different ways in the radio access network and a bearer service that best corresponds to the actual needs can be established through the radio access network. This way, good service quality to the user is ensured and, furthermore, optimization of the capacity of the radio access network is made possible when only correct-type capacity is reserved for each connection.

Determining bearer services in a radio access network

General Packet Radio Service is a new service designed for digital mobile systems. Because of bottlenecks, such as an air interface (Um), queues may be formed in routers. Long transmissions of data may slow the operation of interactive applications so that it is no longer sensible to use the applications. In the routers, separate queues are formed for each service, quality of service, connection, subscriber and/or application/application class. Quality of service can be indicated by providing each packet with an identity indicating the quality, or a change in the quality can be signalled as separate messages. The amount of data sent from a queue at one go may be controlled primarily based on quality of service of the subscriber. When packets are sent from a queue, it is monitored whether only a small number of packets remains in the queue, and if so, these packets are sent as well.

Prioritization of data to be transmitted in a router

A method and an equipment for packet prioritization when routing data packets is presented. Several priority classes are defined for the packets, and a first threshold value and a second, higher, threshold value is defined for each prioity class. In association with each packet, the oldest packet of a given prioritiy class is selected, and if the packet is older than the second threshold value of the priority class concerned, the packet is discarded, and the next priority class is selected. If the packet is older than the first threshold value of the priority class concerned, at least one packet of this priority class is transmitted until the oldest packet in the priority class is younger than the first threshold value of the priority class concerned, whereupon the next priority class is selected.

A cellular radio access network and a location updating in a cordless communications system, in a cellular radio access network ( ), which is connected to one or more core networks ( ) or services (SP to SP ), each of them having a dedicated mobility management. In a cell, identities of all those location areas are broadcast to which said cell belongs. A subscriber terminal (MS) sends to the radio access network only one location updating message irrespective of how many core networks ( ) or services (SP to SP ) have a simultaneously changing location area at a handover from one cell to another. On the basis of the information contained in the location updating message, the network ( ) defines the core networks or services and location areas to which the location updating applies and sends a location updating message informing the new location of the subscriber or the subscriber terminal separately to each defined core network or service.
