A method to control the PDP context of a data packet and a mobile station to realise the method. The mobile station comprises a control element, which controls the classification of a data packet to be sent to a PDP context on basis of a first and a second identifier. The first identifier indicates the application that has created the data packet and the second identifier indicates a separate data flow of the application. The classification process is simplified and thus better suited to a mobile station with limited performance capacity.

Controlling PDP contexts in mobile stations

A method is disclosed for a mobile station (MS) for negotiating a set of Layer 3 parameters with a network device (NW) in association with the setup of a new Packet Data Protocol context. A request message ( ) is created for requesting the setup of a new Packet Data Protocol context, and a set of suggested Layer 3 parameters ( ) is inserted into the created request message. The request message is transmitted to the network device. After receiving from the network device a set of agreed Layer 3 parameters ( ), they are employed within the new Packet Data Protocol context the setup of which was requested.

Method and arrangement for implementing certain negotiations in a packet data network

An implementation of packet data control protocol (PDCP) parameter negotiation in a universal mobile telephone communications service (UMTS) which can also be used to improve GSM/GPRS XID negotiation methods, where the timing for exactly when the new parameters are to take effect must be known includes either a GPRS-type reset solution or a PDCP-header based change indicator solution. In the GPRS-type reset solution, PDCP negotiations are made and then connections are reset to put into effect the new PDCP parameters for use. The second solution is to add a change indicator, e.g., a bit (C-bit) to the PDCP-PDU's header part. The originator informs using this bit that new parameter values are to take effect for use.
