Abstract

The invention relates to a method for selecting transmission entities for supporting services within and between networks. The problem of selecting a transmission entity, taking as well a plurality of service parameter as a plurality of transmission entities into account, is solved by sending a request including a set of parameter to a number of transmission entities. The receiver of said request check, whether they support the requested service, or if they can offer an alternative. They transmission to different transmission entities is performed offering a number of alternatives.

Claims

1. A method for the selection of at least one transmission entity out of a plurality of transmission entities of a telecommunication system, comprising the steps of:

receiving an initiating event notification at a first transmission entity;

determining service parameters and defining a requested service responsive to receipt of the initiating event notification;

requesting submission of bids according to said service parameters from other transmission entities;

receiving a plurality of bids at said first transmission entity;

analysing the plurality of bids; and

selecting at least one transmissions entity of the other transmission entities responsive to the analysed plurality of bids if an appropriate transmission entity is available, wherein the step of selecting further comprises the steps of;

if no appropriate transmission entity is selected, modifying the request for the submission of bids;

sending the modified request for the submission of bids to at least one transmission entity;

receiving at least one bid;

analysing the at least one bid; and

if no appropriate transmission entity is available, rejecting the requested service.

2. The method of claim 1, wherein the step of selecting further comprises the step of deciding which of the plurality of bid is the most appropriate in comparison to the service parameters.

3. The method of claim 1, wherein the step of selecting further comprises the steps of:

sending the bids to another transmission entity; and

receiving an identification of the selected at least one transmission entity.

4. The method of claim 1, wherein the step of receiving of bids is terminated after at least one of a threshold number of received bids or a selected amount of time or a combination of both.

5. The method of claim 1, wherein the request for the submission of bids is sent by using a multicast service.

6. The method of claim 1, wherein the request for the submission of bids is sent by using a broadcast service that is limited to a certain area.

7. The method of claim 1, wherein one transmission entity of the plurality of transmission entities comprises a software agent from another transmission entity, communicating with a software agent of the selected at least one transmission entity.

8. The method to claim 1, further including the step of sending a mobile agent to the first transmission entity in the case of a start/restart of the first transmission entity.

9. The method of claim 1, wherein the request for submission of bids further includes the step of informing the other transmission entities when the reception of a bid will be accepted.

10. A transmission entity, comprising:

a processing unit for processing bids, generating requests for submission of bids, generating bids, and processing bids;

a routing unit receiving the processed bids from the processing unit and generating switching information;

a switching unit for receiving the switching information from the routing unit and switching calls according to said switching information;

an I/O unit for receiving bids from and sending bids to other transmission entitles;

a storage unit for storing bids received by the I/O unit before they are processed by the processing unit; and

an enrol unit for securing reception of requests for submission of bids by performing at least one of the following functions;

subscribing the transmission entity in at least one anycasting group, the at least one anycasting group used for the distribution of requests for the submission of bids;

subscribing the transmission entity in at least one multicasting group, the group used for the distribution of requests for the submission of bids;

receiving a mobile agent from a transmission entity;

sending a mobile agent to a transmission entity;

or

sending the transmission entity'"'"'s address to further transmission entities.

11. A method for the selection of at least one transmission entity out of a plurality of transmission entities of a telecommunication system, comprising the steps of:

receiving an initiating event notification at a first transmission entity;

determining service parameters and defining a requested service responsive to receipt of the initiating event notification;

requesting submission of bids according to said service parameters from other transmission entities;

receiving a plurality of bids at said first transmission entity;

analysing the plurality of bids; and

selecting at least one transmissions entity of the other transmission entities responsive to the analysed plurality of bids if an appropriate transmission entity is available, wherein the step of selecting further comprises the steps of;

if no appropriate transmission entity is selected, selecting one predefined transmission entity.

12. The method of claim 11, wherein the step of selecting further comprises the step of deciding which of the plurality of bid is the most appropriate in comparison to the service parameters.

13. The method of claim 11, wherein the step of selecting further comprises the steps of:

sending the bids to another transmission entity; and

receiving an identification of the selected at least one transmission entity.

14. The method of claim 11, wherein the step of receiving of bids is terminated after at least one of a threshold number of received bids or a selected amount of time or combination of both.

15. The method of claim 11, wherein the request for the submission of bids is sent by using a multicast service.

16. The method of claim 11, wherein the request for submission of bids further includes the step of informing the other transmission entities when the reception of a bid will be accepted.

17. The method of claim 11, wherein said step of selecting said predefined transmission entity further comprises the steps of:

modifying the request for the submission of bids;

sending the modified request for the submission of bids to at least one transmission entity;

receiving at least one bid;

analyzing the at least one bid; and

if no appropriate transmission entity is available, selecting said predefined transmission entity instead.
