Methods and systems for configuring multi-mode mobile stations
View Patent ↗Devices and methods are provided for configuring multi-mode mobile stations. When the number of data sessions available to a multi-mode mobile station changes, the multi-mode mobile station sends information to configuration server sufficient to determine the capability of the network and identify the multi-mode mobile station. The number of data sessions available to a multi-mode mobile station may change for example due to the multi-mode mobile entering a network, changing radio access technologies (RAT) used in the network or changing radio network controllers having the same or a different respective number of data sessions. A configuration server receives the information sent by the multi-mode mobile station and selects configuration information for configuring the multi-mode mobile station to support services/applications that are subscribed to by a user of the multi-mode mobile station. In some embodiments the selection of configuration information is made at least in part based on the information received by the configuration server from the multi-mode mobile station. Once the configuration information has been selected, the configuration server sends the configuration information to the multi-mode mobile station. The multi-mode mobile station receives the multi-mode mobile station specific configuration information and automatically configures itself according to the configuration information.

9. The method of claim 7 further comprising sending data for N services/applications on M PDP contexts, where N≧2, and 1≦M<N.
10. The method of claim 9 wherein sending data for N services/applications on less than N PDP contexts comprises sending data for N services/applications on one PDP context.
11. The method of claim 10 , further comprising sending data for N services/applications on the one active PDP context, wherein sending data comprises:
sending packet based traffic of each of the N services/applications to a router adapted to determine from packet header information in the packet based traffic a particular service/application the packet based traffic is associated with.
12. The method of claim 9 , wherein at least one service/application of the N services/applications comprises an always-on service/application.
13. The method of claim 9 , wherein the N service/applications comprise one or more types of services/applications selected from the group of: wireless application protocol (WAP) service, mobile message service (MMS) wireless modem service, SIP/IMS (Session Initiation Protocol /IP Multimedia Subsystem) service and push e-mail service.
14. The method of claim 1 , wherein configuring the multi-mode mobile station comprises enabling and disabling services/applications for use by the multi-mode mobile station as a function of the configuration information.
15. A method for configuring a multi-mode mobile station over the air comprising:
receiving information comprising at least an identification of the multi-mode mobile station, an identification of a network serving the multi-mode mobile station and an identification of a current radio access technology (RAT) used in the serving network, upon an occurrence of an event that may result in a change in the number of data sessions available to the multi-mode mobile station;
selecting configuration information for the current RAT in the serving network based on the received information for configuring a respective data session used by the multi-mode mobile station, the configuration information comprising a respective configuration profile for each of at least one data session;
