Abstract
In a radio network, the implementation of IP signaling may be used to provide end-to-end Quality of Service. This may be accomplished by mapping corresponding parameters between the IP protocol and the radio network protocol in order to achieve the desired delay and bandwidth requirements. Various events in the state machines of the protocols may also be used to trigger interworking functions.
Claims9
A method in a mobile terminal for providing support for IP signaling, wherein the mobile terminal is in communication with a local user's terminal equipment and is also in communication with a radio network, the method comprising the steps of:
- terminating a PATH message transmitted by the user's terminal equipment;
- determining whether to create a new PDP context or modify an existing PDP context based on the RSVP parameters contained in the PATH message;
- and
- transmitting a request to create or modify the PDP context through the radio network.
A method in a mobile terminal for providing support for IP signaling, wherein the mobile terminal is in communication with a local user's terminal equipment and is also in communication with a radio network, the method comprising the steps of:
- receiving a message from the radio network;
- determining from the message whether an application in the terminal equipment requires RSVP signaling;
- generating a PATH message;
- transmitting the PATH message to the terminal equipment;
- receiving a RESV message from the terminal equipment;
- determining requirements for a PDP context;
- and
- transmitting a request to create or modify the PDP context through the radio network.
A method in a mobile terminal for providing support for IP signaling, wherein the mobile terminal is in communication with a local user's terminal equipment and is also in communication with a radio network, the method comprising the steps of:
- receiving a PATH message transmitted by the user's terminal equipment;
- modifying the PATH message according to a local configuration;
- transmitting the modified PATH message to the radio network;
- receiving a RESV message from the radio network in response to the PATH message;
- determining whether to create a new PDP context or modify an existing PDP context based on RSVP parameters contained in the RESV message;
- transmitting a request to create or modify the PDP context through the radio network;
- receiving a response to the request to create or modify a PDP context from the radio network;
- and
- transmitting the RESV message to the terminal equipment.

- receiving a response to the request to create or modify the PDP context from the radio network;
- and
- transmitting the RESV message to the radio network.
A method to include IP QoS information in a PDP context and to carry the QoS information through a UMTS network, the method comprising the steps of:
- including the QoS information in the PDP context;
- and
- interworking between the QoS information and RSVP in a GGSN.
