Method and apparatus for configuring a voice over ip client connection

Abstract

A method for configuring a connection comprises receiving a request to connect a mobile device having a mobile device type to a communications network including a private branch exchange (PBX) system having a PBX type. Identification information including at least one of the mobile device type and the PBX type is provided. A PBX binding layer is selected based on the identification information. The selected PBX binding layer is provided to the mobile device for interfacing with the PBX system.

1 . A mobile device, comprising: 
 a library of PBX binding layers; and    a processing unit adapted to issue a request to connect to a communications network including a PBX system having a PBX type, receive identification information including at least the PBX type responsive to the request, and select one of the PBX binding layers from the library for interfacing with the PBX system based on the identification information.    
   
   
       2 . The device of  claim 1 , wherein the mobile device has a type, and the processing unit is further adapted to select one of the PBX binding layers from the library for interfacing with the PBX system based on the PBX type and the mobile device type.  
   
   
       3 . The device of  claim 1 , further comprising a user interface, wherein the user interface remains substantially unchanged following a transfer from the communications network to a different communications network having a different PBX type.  
   
   
       4 . The device of  claim 1 , wherein the PBX binding layer includes instructions for configuring access to services on the communications network based on a user profile associated with the mobile device.  
   
   
       5 . The device of  claim 1 , wherein the processing unit is configured to employ a voice over internet protocol (VOIP) for interfacing with the PBX system.  
   
   
       6 . The device of  claim 1 , further comprising a storage device that stores the library of PBX binding layers.  
   
   
       7 . The device of  claim 1 , wherein the library of PBX binding layers is received from a gateway in the communications network.  
   
   
       8 . The device of  claim 7 , wherein the library of PBX binding layers is wirelessly received from the gateway.  
   
   
       9 . A mobile device comprising: 
 a storage device configured to store a first PBX binding layer that facilitates communication between the mobile device and a first PBX system in a communications network, and to store a second PBX binding layer that facilitates communication between the mobile device and a second PBX system in the communications network; and    a processing unit coupled to the storage device, the processing unit being adapted to receive information indicative of a PBX type, select the first PBX binding layer if the PBX type identifies the first PBX system, and select the second PBX binding layer if the PBX type identifies the second PBX system.    
   
   
       10 . The mobile device of  claim 9 , the processing unit being adapted to reconfigure the mobile device to load the second PBX binding layer when the mobile device roams from a first area corresponding to the first PBX system to a second area corresponding to the second PBX system.  
   
   
       11 . The mobile device of  claim 9 , the processing unit being adapted to reconfigure the mobile device to load the first PBX binding layer when the mobile device roams from a second area corresponding to the second PBX system to a first area corresponding to the first PBX system.  
   
   
       12 . The mobile device of  claim 9 , further comprising a user interface, wherein the user interface remains substantially unchanged following a transfer from the first PBX system to the second PBX system, and following a transfer from the second PBX system to the first PBX system.  
   
   
       13 . The mobile device of  claim 9 , wherein the processing unit is configured to employ a voice over internet protocol (VOIP) for interfacing with the first PBX system and for interfacing with the second PBX system.  
   
   
       14 . The mobile device of  claim 9 , wherein the storage device is configured to receive the first PBX binding layer and the second PBX binding layer from a gateway in the communications network.  
   
   
       15 . The device of  claim 14 , wherein the first PBX binding layer and the second PBX binding layer are wirelessly received from the gateway.
