Priority Bearers In A Mobile Telecommunication Network
First Claim
1. A method for transferring a packet on a bearer in a mobile telecommunication system, the system comprising:
- an operator;
a mobile terminal;
a network with one or more network nodes (Node B) supporting flow of a packet to the mobile terminal (downlink) and from the mobile terminal (uplink);
the method comprising the steps of;
setting up multiple parallel bearers for bearing the packets across a radio interface;
associating each of 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;
using the bearer priority level to prioritise access to and associated reservation of the radio resources, characterized in setting up said multiple parallel bearers before a session on application level is initiated for bearing the packet across a radio interface; and
, if radio resources should be reserved, reserving the radio resources of said network for any of the multiple parallel bearers after said setting up of the bearers.

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 prioritise 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 prioritise the access to the radio resources.

2. A method for transferring an uplink packet on a bearer in a mobile telecommunication system, the system comprising:
-
an operator;
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);
the method comprises the steps of;
setting up multiple parallel bearers for bearing packets across a radio interface;
associating each of said multiple parallel bearers with a bearer priority level of traffic handling;
determining a priority level of said uplink packet;
mapping the uplink 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, the step of mapping is characterized in that the network determines the bearer to which the uplink packet shall be mapped, based on matching the priority level of the uplink packet with the priority level of the bearer;
the network constructs an uplink packet filter for the determined bearer and signals this to the mobile terminal;
once the uplink packet is to be transferred, the mapping is performed within the mobile terminal, based on the uplink packet filter signalled from the network. - View Dependent Claims (3, 4, 5, 6)

7. A method for transferring a packet on a bearer in a mobile telecommunication system, the system comprising:
-
an operator;
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);
the method comprises the steps of;
setting up one or multiple parallel bearers for bearing packets across a radio interface;
associating said one or 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, characterized in that 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.

8. A method for transferring a packet on a bearer in a mobile telecommunication system, the system comprising:
-
an operator;
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), the method comprises the steps of;
setting up multiple parallel bearers for bearing the packet across a radio interface;
associating each of 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, characterised in that the step of determining a priority level of said packet is decided by a policy control function in the network, according to policies configured by the operator. - View Dependent Claims (9)

10. A method for transferring a packet on a bearer in a mobile telecommunication system, the system comprising:
-
an operator;
a mobile terminal;
a network with one or more network nodes (Node B) supporting flow of a packet to the mobile terminal (downlink) and from the mobile terminal (uplink);
a mobile connection between the network and said mobile terminal, the method comprising the steps of;
setting up one or multiple parallel bearers for bearing packets across a radio interface;
associating each of said one or 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;
deciding to switch the channel state of the mobile connection by state transition signalling between the network and the mobile terminal, based on arrival of the packet and packet arrival statistics from the past; and
using the bearer priority level to prioritise the access to the radio resources where the step of using the bearer priority level to prioritise the access to the radio resources is characterized in that;
the network reassigns resources from a mobile terminal with only low bearer priority level(s) to a mobile terminal with a high bearer priority level, by switching the mobile connection of the high priority terminal to a channel state permitting a high data rate, and switching the mobile connection of the low priority terminal to a channel state permitting lower data rates.
