Priority bearers in a mobile telecommunication network
First Claim
1. A method for transferring a packet on a bearer in a mobile telecommunication system, wherein the system comprises:
- a mobile terminal;
a network with one or more network nodes supporting flow of a packet to the mobile terminal (downlink) and from the mobile terminal (uplink);
said method comprising the steps of;
setting up one or multiple parallel bearers for bearing packets across a radio interface;
associating said multiple parallel bearers with a bearer priority level of traffic handling;
determining a priority level of said packet;
mapping the packet to one of the multiple parallel bearers based on the priority level; and
,using the bearer priority level to prioritise the access to the radio resources;
wherein the step of setting up one or multiple parallel bearers consists in that the network initiates the set up of a bearer with a signal to the mobile terminal; and
,wherein the mapping of a packet in the downlink direction to one of the multiple bearers is controlled by configuring a packet filter for the bearer, containing the IP address and/or port number and/or Protocol Id of the packet, in a Gateway node terminating the bearer.

Abstract
Method for switching a packet to a bearer in a mobile telecommunication network, by setting up multiple parallel bearers for bearing the packet across a radio interface; associating the bearers with a bearer priority level of traffic handling; determining a priority level of the packet; mapping the packet priority level to the bearer priority level; switching the packet to one of the bearers based on the mapping; using the bearer priority level to prioritize the access to the radio resources. A further method for switching a packet by setting up multiple parallel bearers without resource reservation; associating each of the bearers with a bearer priority level; mapping a flow of packets to one of the bearer priority levels, when a service is started; switching each packet to one of the multiple bearers based on the mapping; using the bearer priority level to prioritize the access to the radio resources.

15. A method for transferring a packet on a bearer in a mobile telecommunication system, wherein the system comprises:
-
a mobile terminal; a network with one or more network nodes supporting flow of a packet to the mobile terminal (downlink) and from the mobile terminal (uplink); said method comprising the steps of; setting up one or multiple parallel bearers for bearing packets across a radio interface; associating said multiple parallel bearers with a bearer priority level of traffic handling; determining a priority level of said packet; mapping the packet to one of the multiple parallel bearers based on the priority level; and
,using the bearer priority level to prioritise the access to the radio resources; wherein the step of setting up one or multiple parallel bearers consists in that the network initiates the set up of a bearer with a signal to the mobile terminal; wherein an event triggers the setting up of multiple parallel bearers, the event comprising one of the group including; the establishment of a first bearer for Internet Protocol connectivity; a user of the mobile terminal accessing a specific Universal Resource Locator or Internet Protocol address though the mobile terminals triggers said setting up of multiple parallel bearers; and
,a signalling message on application level, such as a Session Initiation Protocol message.

17. A method for transferring a packet on a bearer in a mobile telecommunication system, wherein the system comprises:
-
a mobile terminal; a network with one or more network nodes supporting flow of a packet to the mobile terminal (downlink) and from the mobile terminal (uplink); said method comprising the steps of; setting up one or multiple parallel bearers for bearing packets across a radio interface; associating said multiple parallel bearers with a bearer priority level of traffic handling; determining a priority level of said packet; mapping the packet to one of the multiple parallel bearers based on the priority level; and
,using the bearer priority level to prioritise the access to the radio resources; wherein the step of setting up one or multiple parallel bearers consists in that the network initiates the set up of a bearer with a signal to the mobile terminal; wherein the step of determining a packet priority level is based on a parameter selected from the group comprising; a type of application flow; a service level; a charging level; a Universal Resource Locator of an application server; an Internet Protocol address of an application server; a general subscription level of the subscriber; and
,whether the subscriber is authorised to activate the service.
