Abstract

In methods and devices for providing a guaranteed quality of service to a subscriber of a service in a cellular radio system, a start position and an end position are received along with a required quality of service, QoS. Cell site positions are associated with possible user geographical/street paths that will take the subscriber from the start position to the end position and search for paths that will guarantee the required QoS. Based on the search the path that best satisfies the entered input criteria is selected and output to the subscriber.

Claims

1. A method of providing a guaranteed quality of service to a subscriber of a service in a cellular radio system, the method comprising:

receiving a start and an end position as a first input criteria from the subscriber,

receiving a required quality of service, QoS, as a second input criteria from the subscriber,

associating cell site positions with possible user geographical/street paths that will take the subscriber from the start position to the end position and search for paths that will guarantee the required QoS,

selecting the path that best satisfies the received first and second input criteria, wherein the path is selected, at least in part, based on a cost function having as input parameters one or more of;

coverage, cell load and handover cost, and

outputting the selected path to the subscriber.

2. The method according to claim 1 wherein other input criteria are received.

3. The method according to claim 2, wherein the other criteria is one or more of:

a maximum path length, a maximum estimated time to travel from the start position to the end positions, a stop position along the path from the start position to the end position, and a time when the travel from the start position to the end position is to take place.

4. The method according to claim 1, further comprising prompting the cellular radio system to reserve resources for the selected path.

5. The method according to claim 1, further comprising setting one or more parameters for the subscriber path to fulfill the QoS requirement.

6. The method according to claim 1, further comprising continuously determining the subscriber position and warning about one or more of interruptions, coverage issues and overload cells in response to the determined position.

7. A planning device for providing a guaranteed quality of service to a subscriber of a service in a cellular radio system, the device comprising:

controller circuitry for receiving a start position and an end position as a first input criteria from the subscriber,

controller circuitry for receiving a required quality of service, QoS, as a second input criteria from the subscriber,

controller circuitry for associating site positions with possible user geographical/street paths that will take the subscriber from the start position to the end position and search for paths that will guarantee the required QoS,

controller circuitry for selecting the path that best satisfies the received first and second input criteria, wherein the path is selected, at least in part, based on a cost function having as input parameters one or more of;

coverage, cell load and handover cost, and

controller circuitry for outputting the selected path to the subscriber.

8. The planning device according to claim 7, wherein the planning device is configured to receive other input criteria.

9. The planning device according to claim 8, wherein the other criteria is one or more of:

a maximum path length, a maximum estimated time to travel from the start position to the end position, a stop position along the path from the start position to the end position, and a time when the travel from the start position to the end position is to take place.

10. The planning device according to claim 7 wherein the planning device is configured to prompt the cellular radio system to reserve resources for the selected path.

11. The planning device according to claim 7, wherein the planning device is configured to prompt the cellular radio system to set one or more parameters for the subscriber path to fulfill the QoS requirement.

12. The planning device according to claim 7, wherein the planning device is configured to continuously determine the subscriber position and warning about one or more of interruptions, coverage issues and overload cells in response to the determined position.
