Radio sharing for multiple wireless subscriber identities

Abstract

The described technology is generally directed towards sharing a radio by multiple subscriber identities at a device. A time division multiplexing pattern at the device radio gives primary radio use to a first subscriber identity, while also providing time windows for radio use to a second subscriber identity. In response to a communication by the second subscriber identity, the time division multiplexing pattern can be changed to give the primary radio use to the second subscriber identity. Also, a radio resource control protocol can designate appropriate states for the different subscriber identities, designating the subscriber identity with primary radio use as connected, while the other subscriber identity is designated as inactive or idle.

What is claimed is: 
     
         1 . A method, comprising:
 facilitating, by a device comprising a processor, usage of a first time division multiplexing pattern by a radio of the device,   wherein, during the usage of the first time division multiplexing pattern, a radio resource control protocol is in an idle state for first subscriber radio use, and the radio resource control protocol is in a connected state for second subscriber radio use; and   in response to a communication associated with the first subscriber radio use being communicated, facilitating, by the device, usage of a second time division multiplexing pattern by the radio,   wherein, during the usage of the second time division multiplexing pattern, the radio resource control protocol is in the connected state for the first subscriber radio use, and the radio resource control protocol is in the idle state for the second subscriber radio use.   
     
     
         2 . The method of  claim 1 , wherein the first time division multiplexing pattern comprises first time windows for the first subscriber radio use and second time windows for the second subscriber radio use, and wherein the second time division multiplexing pattern comprises third time windows for the first subscriber radio use and fourth time windows for the second subscriber radio use. 
     
     
         3 . The method of  claim 1 , wherein the first subscriber radio use is associated with a first subscriber identity stored at a first subscriber identity module, and wherein the second subscriber radio use is associated with a second subscriber identity stored at a second subscriber identity module. 
     
     
         4 . The method of  claim 1 , wherein the communication associated with the first subscriber radio use comprises a random access channel communication. 
     
     
         5 . The method of  claim 4 , wherein the random access channel communication comprises a two-step random access channel communication. 
     
     
         6 . The method of  claim 1 , wherein the communication associated with the first subscriber radio use comprises a radio resource control protocol connection re-establishment message. 
     
     
         7 . The method of  claim 1 , wherein, during the usage of the first time division multiplexing pattern, the second subscriber radio use comprises a voice call. 
     
     
         8 . The method of  claim 1 , wherein the communication associated with the first subscriber radio use is responsive to a page communication. 
     
     
         9 . A device, comprising:
 a processor; and   a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
 setting a first time division multiplexing pattern to be used at the device, 
 wherein, when the first time division multiplexing pattern is being used, a radio resource control protocol is in a connected state for first subscriber radio usage, and the radio resource control protocol is an idle state for second subscriber radio usage; and 
 in response to participating in a communication associated with a second subscriber radio usage, setting a second time division multiplexing pattern to be used at the device, 
 wherein, when the second time division multiplexing pattern is being used, the radio resource control protocol is in an inactive state for the first subscriber radio usage, and the radio resource control protocol is in the connected state for the second subscriber radio usage. 
   
     
     
         10 . The device of  claim 9 , wherein the first time division multiplexing pattern and the second time division multiplexing pattern facilitate sharing of a radio between the first subscriber radio usage and the second subscriber radio usage. 
     
     
         11 . The device of  claim 9 , wherein the first time division multiplexing pattern comprises first time windows for the first subscriber radio usage and second time windows for the second subscriber radio usage, and wherein the second time division multiplexing pattern comprises third time windows for the first subscriber radio usage and fourth time windows for the second subscriber radio usage. 
     
     
         12 . The device of  claim 9 , wherein, when the first time division multiplexing pattern is being used, the first subscriber radio usage comprises an active data session, and wherein, when the second time division multiplexing pattern is being used, the second subscriber radio usage comprises communication of voice call data pursuant to a voice call. 
     
     
         13 . The device of  claim 9 , wherein participating in the communication associated with the second subscriber radio usage is responsive to a voice call page communication received at the device. 
     
     
         14 . The device of  claim 9 , wherein participating in the communication associated with the second subscriber radio usage comprises initiating a random access channel communication, and wherein the random access channel communication comprises a radio resource control protocol connection re-establishment message. 
     
     
         15 . The device of  claim 9 , wherein, when the second time division multiplexing pattern is being used, the second subscriber radio usage comprises communication of voice call data pursuant to a voice call, and wherein the operations further comprise setting a third time division multiplexing pattern to be used at the device in response to a termination of the voice call. 
     
     
         16 . A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
 using a time division multiplexing pattern at a device, wherein the time division multiplexing pattern comprises different time windows for first radio use associated with a first subscriber identity and second radio use associated with a second subscriber identity; and   in response to receiving a page communication associated with a paged subscriber identity from a group of identities, the group comprising the first subscriber identity and the second subscriber identity, generating a time division multiplexing pattern coordination request in order to modify the time division multiplexing pattern at the device.   
     
     
         17 . The non-transitory machine-readable medium of  claim 16 , wherein the operations further comprise sending the time division multiplexing pattern coordination request via a first network associated with the first subscriber identity or via a second network associated the second subscriber identity.
