Systems and methods for determining that a maximum number of IP sessions have been established are provided. There are instances when the mobile device transmits a request to the wireless network. According to an aspect, in the event that the maximum number of IP sessions is already established for the mobile device, the wireless network transmits a response indicating that the request cannot be fulfilled. The mobile device determines based on the response that the maximum number of IP sessions is already established, which allows the mobile device to determine the maximum number of IP sessions that can be supported so that IP sessions can be managed accordingly.

System and method for determining that a maximum number of IP sessions have been established

Systems and Method are provided for managing IP sessions based on how many IP sessions are supported. According to an embodiment of the application, the wireless network determines how many IP sessions can be supported for the mobile device residing in a given area such as a routing area, and to transmit to the mobile device an identification of how many IP sessions can be supported. According to another embodiment of the application, the mobile device receives the identification of how many IP sessions can be established, and manages IP sessions based on the identification. Since the mobile device is privy to how many IP sessions can be established, the mobile device is able to properly manage IP sessions.

System and method for managing IP sessions based on how many IP sessions are supported

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.
