Abstract

The invention provides methods method for access selection in a Multi-Access Network offering a plurality of Access Technologies (AT). The device may comprises a Multi Access Management entity (MAM) and a plurality of Generic Link Layer Entities (GLL) associated to a plurality of Accesses (A) according to said plurality of Access Technologies (AT). The access selection comprises an Access determination and an Access configuration. In a first step a Generic Link Layer Entity (GLL) determines one or more Generic Performance Metrics (GPM) corresponding to one or more configurations of the Access (A). The Generic Link Layer Entity (GLL) sends the determined one or more Generic Performance Metrics (GPM) corresponding to one or more configurations of the access (A) to the Multi Access Management entity (MAM). The Multi Access Management entity (MAM) determines from received Generic Performance Metrics (GPM), which Access (A) offers a configuration (GPM), which is suited for an application/bearer requirements. Then, said Multi Access Management entity (MAM) sends the determined configuration to the Generic Link Layer Entity (GLL) associated to the determined Access (A). The determined Generic Link Layer Entity (GLL) configures the Access (A) based on the determined configuration received from the Multi Access Management entity (MAM). Furthermore, the invention relates to corresponding devices, modules and software.

Claims

1. A method for Access (A) selection in a Multi-Access Network offering a plurality of Access Technologies (T), the Multi-Access Network comprising a Multi-access Management Entity (MAM) and a plurality of Generic Link Layer Entities (GLL) associated with a plurality of Accesses (A) according to said plurality of Access Technologies (AT), the access selection comprising an Access determination and an Access configuration, the method comprising the steps of:

One or more GLL determining a plurality of Generic Performance Metrics (GPM) corresponding to a plurality of configurations of the plurality of Accesses (A);

the one or more of GLL sending the determined plurality of GPM to the MAM, said MAM determining from the determined plurality of GPM which one of the plurality of Accesses provides a configuration appropriate for application and bearer requirements;

said MAM sending the determined configuration to the one or more GLL associated to the one of the plurality of Accesses; and

said one or more GLL configuring the one of the plurality of Accesses (A) based on the determined configuration received from the MAM.

2. The method according to claim 1, further comprising the step of said one or more GLL associated with the determined Access (A) sends the plurality of Generic Performance Metrics (GPM) for the determined configuration.

3. The method according to claim 1, further comprising the steps of:

the Multi Access Management entity sending bearer requirements to the one or more GLL before the one or more GLL determines the plurality of Generic Performance Metrics (GPM) corresponding to the configurations of the Access (A), and

the one or more GLL having received bearer requirements determining the Generic Performance Metrics (GPM) on the basis of the received bearer requirements, whereby the Generic Performance Metrics (GPM), which do not meet the received bearer requirements, will not be reported.

4. The method according to claim 1, further comprising said one or more GLL determining the Generic Performance Metrics (GPM) corresponding to the configurations of the Access (A) by analytical derivation.

5. The method according to claim 1, further comprising the step of said one or more GLL determining the Generic Performance Metrics (GPM) corresponding to configuration of the Access (A) by way of mapping tables.

6. A method for a Generic Link Layer Entity (GLL) for providing Generic Performance Metrics (GPM) for access selection in a Multi-Access Network providing a plurality of Access Technologies (AT), the method comprising the steps of:

determining Generic Performance Metrics (GPM) corresponding to a configuration of an Access (A),

sending the determined Generic Performance Metrics (GPM) corresponding to the configuration of the Access (A) to a Multi Access Management entity (MAM),

receiving from said Multi Access Management entity (MAM) a determined configuration, and

configuring the Access (A) based on the determined configuration received from the Multi Access Management entity (MAM).

7. The method according to claim 6, further comprising the step of sending the generic performance metrics (GPM) for the determined configuration.

8. The method according to claim 6, further comprising the step of:

receiving from the Multi Access Management entity (MAM) bearer requirements, whereby the determination of the Generic Performance Metrics (GPM) is based on the received bearer requirements, and whereby Generic Performance Metrics (GPM), which do not meet the received bearer requirements, will not be reported.

9. The method according to claim 6, wherein said determination of the Generic Performance Metrics (GPM) corresponding to the configuration of the Access (A) is based on an analytical derivation.

10. The method according to claim 6, wherein said determination of the Generic Performance Metrics (GPM) corresponding to the configuration of the Access (A) is based on mapping tables.

11. A method for a Multi Access Management entity (MAM) for Access (A) selection in a Multi-Access Network providing a plurality of Access Technologies (AT), the method comprising the steps of:

receiving determined Generic Performance Metrics (GPM) corresponding to a configuration of an Access (A) from a Generic Link Layer Entity (GLL), whereby an Access (A) is associated to the Generic Link Layer Entity (GLL),

determining from said received Generic Performance Metrics (GPM), which Access (A) provides a configuration appropriate for application and bearer requirements,

sending the determined configuration to the Generic Link Layer Entity (GLL) associated to the determined Access (A) for causing the determined Generic Link Layer Entity (GLL) to configure the Access (A) based on the determined configuration received from the Multi Access Management entity (MAM), and

sending bearer requirements to one or more Generic Link Layer Entities (GLL).

12. A device for Access (A) selection in a Multi-Access Network providing a plurality of Access Technologies (AT), the device comprising:

a plurality of Accesses (A) according to said plurality of Access Technologies (AT); and

an associated, non-transitory machine-readable medium comprising instructions which, when executed by a processor cause the device to;

determine Generic Performance Metrics (GPM) corresponding to a configuration of a plurality of Accesses (A), and

determine from the Generic Performance Metrics (GPM), which Access (A) provides a configuration, appropriate for application and bearer requirements, whereby said Generic Performance Metrics (GPM) are programmed to configure the Access (A) based on the determined configuration.

13. A module for providing Generic Performance Metrics (GPM) for Access (A) selection in a Multi-Access Network providing a plurality of Access Technologies (AT), the module comprising:

an associated, non-transitory machine-readable medium comprising instructions which, when executed by a processor cause the module to;
