Method for backup connection and an electronic device using the method
First Claim
1. A method for establishing a wireless data transfer connection between a remote application and a controlling application, where the wireless link from the remote application is implemented by a wireless terminal connected to the remote application, the method comprising:
- arranging a group of allowable connection parameter settings in a pre-determined order, each connection parameter setting corresponding to a different service bearer;
attempting to use a default connection parameter setting, wherein the default connection parameter setting corresponds to a default service bearer;
detecting that the default service bearer is not usable to establish a wireless data transfer connection;
serially selecting another connection parameter setting for the wireless link from the group of allowable connection parameter settings in the pre-determined order one-after-another until a usable service bearer is identified to perform the wireless data transfer; and
after identification of the usable service bearer and a successful wireless data transfer, setting the default connection parameter setting to the usable service bearer.

Abstract
The invention relates to a method for establishing an at least partially wireless data transfer connection between a remote application and a controlling application. The wireless connection is implemented by a wireless terminal connected to the remote application. The wireless terminal can select from a group of allowable connection parameter settings a usable connection parameter setting for the wireless link, if a default connection parameter setting for the wireless link is not usable. The invention relates also to a wireless terminal using the method and a computer program implementing the method in the wireless terminal.

5. A wireless terminal configured to be connected to a remote application, the wireless terminal comprising transmitting and receiving means, a memory, an application interface and a control unit, where the control unit further comprises a control logic, the control logic configured to attempt to use a default connection parameter setting, wherein the default connection parameter setting corresponds to a particular service bearer;
- to detect that the default connection parameter setting for the wireless link is not usable; and
to serially select another connection parameter setting for the wireless link from a group of allowable connection parameter settings, wherein each of the allowable connection parameter settings corresponds to a different service bearer, the group of allowable connection parameter settings being ordered in a pre-determined order, and wherein the connection parameter settings are serially selected, one-after-another, in the pre-determined order, until a usable service bearer is identified to perform the wireless data transfer; and
after identification of the usable service bearer and a successful wireless data transfer, to set the default connection parameter setting to the usable service bearer. - View Dependent Claims (6, 7, 8, 9)

10. A memory embodying a computer program configured to perform operations that control a connection setup of a wireless terminal when executed by control logic of the wireless terminal, the operations comprising:
-
detecting a need for a data transfer across a wireless link; checking a default connection parameter setting, wherein the default connection parameter setting corresponds to a particular service bearer; attempting to establish a connection with the default connection parameter setting; determining if the data transfer connection has been established using the default connection parameter setting; if no data transfer connection has been established, trying a second time to establish a data transfer connection with the default connection parameter setting; if no data transfer connection is established after the second try, serially selecting another connection parameter setting for the wireless link from a group of allowable connection parameter settings, wherein the group of allowable connection parameter settings is ordered in a pre-determined order, each of the connection parameter settings in the group of allowable connection parameter settings corresponding to a different service bearer, and wherein the connection parameter settings are serially selected, one-after-another in the pre-determined order, until a usable service bearer is found; establishing a data transfer connection with the usable service bearer; and after identification of a usable service bearer and a successful wireless data transfer, setting the default connection parameter setting to the usable service bearer. - View Dependent Claims (11)

12. A method for establishing a wireless data transfer connection between a remote application and a controlling application, where the wireless link from the remote application is implemented by a wireless terminal connected to the remote application, the method comprising:
-
detecting that a default connection parameter setting for the wireless link is not usable, wherein the default connection parameter setting corresponds to a particular service bearer; determining if a command has been received from a controlling application changing a default order for selection of connection parameter settings to a new order and, if so, selecting a connection parameter setting in the new order established by the controlling application, wherein each of the connection parameter settings in the default and new orders corresponds to a different service bearer; and if no command has been received from the controlling application, selecting the connection parameter setting for the wireless link from a group of allowable connection parameter settings in the default order; serially selecting another connection parameter setting for the wireless link from the group of allowable connection parameter settings in the default order one-after-another until a usable connection parameter setting is identified, wherein the usable connection parameter setting corresponds to a particular service bearer; and after identification of a usable service bearer and a successful wireless data transfer, setting the default connection parameter setting to the usable service bearer.

13. A method for establishing a wireless data transfer connection between a remote application and a controlling application, where the wireless link from the remote application is implemented by a wireless terminal connected to the remote application, the method comprising:
-
arranging a group of allowable service operators in a pre-determined order, wherein a service operator ordered first comprises a default service operator; arranging a group of allowable connection parameter settings in a pre-determined order, wherein each of the connection parameter settings corresponds to a different service bearer, and wherein a connection parameter setting ordered first comprises a default connection parameter setting; attempting to use the default service operator; if the default service operator is not usable, serially selecting another service operator from the group of allowable service operators in the pre-determined order one-after-another until a usable service operator is found; detecting a need for a data transfer over a wireless link; attempting to use the default connection parameter setting; detecting that the default connection parameter setting is not usable; serially selecting another connection parameter setting for the wireless link from the group of allowable connection parameter settings in the pre-determined order one-after-another until a usable connection parameter setting is identified, wherein the usable connection parameter setting corresponds to a particular service bearer; and after identification of a usable service bearer and a successful wireless data transfer, setting the default connection parameter setting to the usable service bearer.
