Abstract

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 (511) is created for requesting the setup of a new Packet Data Protocol context, and a set of suggested Layer 3 parameters (510) 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 (514), they are employed within the new Packet Data Protocol context the setup of which was requested.

Claims

1. A method for a mobile station for negotiating a set of upper layer parameters with a network device, comprisinges the steps of

creating a request message for requesting the setup of a new Packet Data Protocol context,

inserting into the created request message a set of suggested upper layer parameters,

transmitting the request message to the network device,

receiving from the network device a set of agreed upper layer parameters and

employing the agreed upper parameters within the new Packet Data Protocol context the setup of which was requested.

2. A method according to claim 1, wherein the step of inserting into the created request message a set of suggested upper layer parameters comprises inserting into the created request message a set of Layer 3 parameters, and the step of receiving from the network device a set of agreed upper layer parameters comprises receiving from the network device a set of Layer 3 parameters.

3. A method according to claim 1, wherein the step of inserting into the created request message a set of suggested upper layer parameters comprises inserting into the created request message a set of L3CE parameters, and the step of receiving from the network device a set of agreed upper layer parameters comprises receiving from the network device a set of L3CE parameters.

4. A method according to claim 1, wherein the step of inserting into the created request message a set of suggested upper layer parameters comprises inserting into the created request message a set of upper layer parameters that are common to all Packet Data Protocol contexts of the mobile station.

5. A method for a network device for negotiating a set of upper layer parameters with a mobile station, comprising the steps of

creating an accept message for accepting a routing area update transmitted by the mobile station,

inserting into the created accept message a set of suggested upper layer parameters,

transmitting the accept message to the mobile station,

receiving from the mobile station a set of agreed upper layer parameters and

employing the agreed upper layer parameters within the Packet Data Protocol context which was subject to the negotiation.

6. A method according to claim 5, additionally comprising the step of providing said set of suggested upper layer parameters from an upper layer protocol entity to a mobility management protocol entity before inserting them in the created accept message.

7. A method according to claim 5, wherein said step of receiving from the mobile station a set of agreed upper layer parameters comprises extraction of said parameters from a received routing area update complete message.

8. A method according to claim 5, wherein each set of upper layer parameters is a set of Layer 3 parameters.

9. A method according to claim 5, wherein each set of upper layer parameters is a set of L3CE parameters.

10. A method according to claim 5, wherein said set of upper layer parameters is common to all Packet Data Protocol contexts of the mobile station.
