Coordinating data calls on a mobile device with multiple modems

Abstract

A method for inter-modem coordination is described. A first data connection to a network in a first network coverage area using a first air interface provided by a first modem is established. The method also includes detecting a second network coverage area with a second air interface provided by a second modem. A data call state of the second modem is determined by the first modem. The first data connection to the network by the first modem is terminated when the data call state of the second modem is no data call. A data call state of the first modem is determined by the second modem. A second data connection to the network using the second air interface provided by the second modem is initiated when the data call state of the first modem is no data call.

What is claimed is: 
     
         1 - 8 . (canceled) 
     
     
         9 . A method for inter-modem coordination, comprising:
 establishing a data connection between a tethered terminal and a network on a first air interface using a first modem;   receiving notification of a message from the network on a second air interface using a second modem;   determining a data call state of the first modem by the second modem; and   receiving the message over the second air interface for the tethered terminal using the second modem when the data call state of the first modem is no data call.   
     
     
         10 . The method of  claim 9 , further comprising determining a call type of the first modem by the second modem when the data call state of the first modem is one of bringing up data call, data call established, and data call being torn down. 
     
     
         11 . The method of  claim 10 , further comprising rejecting the message over the second air interface when the call type is tethered. 
     
     
         12 . The method of  claim 10 , further comprising receiving the message over the second air interface using the second modem when the call type is embedded. 
     
     
         13 . The method of  claim 9 , wherein receiving the message over the second air interface using the second modem comprises establishing a tethered circuit switched data call with a tethered device on an Rm link. 
     
     
         14 . The method of  claim 9 , wherein the data call state is one of no data call, establishing a data call, data call established and data call being torn down. 
     
     
         15 . The method of  claim 9 , wherein the message is a paging message. 
     
     
         16 . The method of  claim 9 , wherein the method is performed by a user equipment comprising the first modem and the second modem. 
     
     
         17 - 24 . (canceled) 
     
     
         25 . A wireless device configured for inter-modem coordination, comprising:
 a processor;   memory in electronic communication with the processor;   instructions stored in the memory, the instructions being executable by the processor to:
 establish a data connection between a tethered terminal and a network on a first air interface using a first modem; 
 receive notification of a message from the network on a second air interface using a second modem; 
 determine a data call state of the first modem by the second modem; and 
 receive the message over the second air interface for the tethered terminal using the second modem when the data call state of the first modem is no data call. 
   
     
     
         26 . The wireless device of  claim 25 , wherein the instructions are further executable to determine a call type of the first modem by the second modem when the data call state of the first modem is not no data call. 
     
     
         27 . The wireless device of  claim 26 , wherein the instructions are further executable to reject the message over the second air interface when the call type is tethered. 
     
     
         28 . The wireless device of  claim 26 , wherein the instructions are further executable to receive the message over the second air interface using the second modem when the call type is embedded. 
     
     
         29 . The wireless device of  claim 25 , wherein receiving the message over the second air interface using the second modem comprises establishing a tethered circuit switched data call with a tethered device on an Rm link. 
     
     
         30 . The wireless device of  claim 25 , wherein the data call state is one of no data call, establishing a data call, data call established and data call being torn down. 
     
     
         31 . The wireless device of  claim 25 , wherein the message is a paging message. 
     
     
         32 - 36 . (canceled) 
     
     
         37 . A wireless device configured for inter-modem coordination, comprising:
 means for establishing a data connection between a tethered terminal and a network on a first air interface using a first modem;   means for receiving notification of a message from the network on a second air interface using a second modem;   means for determining a data call state of the first modem by the second modem; and   means for receiving the message over the second air interface for the tethered terminal using the second modem when the data call state of the first modem is no data call.   
     
     
         38 . A computer-program product for inter-modem coordination, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions comprising:
 code for causing a wireless device to establish a data connection between a tethered terminal and a network on a first air interface using a first modem;   code for causing the wireless device to receive notification of a message from the network on a second air interface using a second modem;   code for causing the wireless device to determine a data call state of the first modem by the second modem; and   code for causing the wireless device to receive the message over the second air interface for the tethered terminal using the second modem when the data call state of the first modem is no data call.
