Abstract

A radio frequency communications system ( 100 ) includes wireless terminals ( 102 ) and base sites ( 104 ). The wireless terminals communicate with the base sites over a radio frequency channel ( 106 ). The base sites are interconnected to each other and other network elements via a packet network. The communication system has a radio frequency channel ( 400 ) with time slots ( 406, 408 ) for transmission of both delay-sensitive data, such as streaming audio and video, and non-delay-sensitive data. A method and apparatus are provided for determining whether a time slot in the radio frequency channel is to be allocated to delay-sensitive data or non-delay-sensitive data ( 704, 706, 708 ). Each packet of data transmitted over the wireless channel has a type of service field ( 900 ). The type of service field has a precedence or priority value ( 902 ) and a service type ( 904 ). The priority values are used to determine which packet should be transmitted across the radio frequency channel next and the service type determines the transmission protocol.

Claims

exact text as granted — not AI-modified
1 - 10 . (canceled)  
     
     
         11 . In a wireless communications system where packets of data are transmitted over a wireless channel, a method for determining which packet of a plurality of packets should be transmitted next over the wireless channel, the method comprising the steps of: 
 determining a precedence value for each packet to be transmitted over the wireless channel;    selecting a packet to be transmitted next over the wireless channel based on the precedence value, wherein the precedence value for each packet is determined based on whether the each packet includes data to set up communications over the wireless channel.    
     
     
         12 . The method of  claim 11  wherein the precedence value for each packet is determined based on whether the each packet includes audio or video data.  
     
     
         13 . The method of  claim 12  wherein the precedence value for each packet is determined based on whether the each packet includes emergency data.  
     
     
         14 . The method of  claim 13  wherein the precedence value for each packet is determined based on whether the each packet includes non-delay critical data.  
     
     
         15 . The method of  claim 11  wherein the precedence value for a packet that includes data to set up communications over the wireless channel is of a higher priority than precedence values for other packets.  
     
     
         29 . In a wireless communications system where packets of data are transmitted over a wireless channel, an apparatus for determining which packet of a plurality of packets should be transmitted next over the wireless channel, the apparatus comprising: 
 a processor that: 
 determines a precedence value for each packet to be transmitted over the wireless channel; and  
   a wireless modem coupled to the processor that: 
 selects a packet to be transmitted next over the wireless channel based on the precedence value, wherein the precedence value for each packet is determined based on whether the each packet includes data to set up communications over the wireless channel.  
   
     
     
         30 . The apparatus of  claim 29  wherein the precedence value for each packet is determined based on whether the each packet includes audio or video data.  
     
     
         31 . The apparatus of  claim 30  wherein the precedence value for each packet is determined based on whether the each packet includes emergency data.  
     
     
         32 . The apparatus of  claim 31  wherein the precedence value for each packet is determined based on whether the each packet includes non-delay critical data.  
     
     
         33 . The method of  claim 29  wherein the precedence value for a packet that includes data to set up communications over the wireless channel is of a higher priority than precedence values for other packets.  
     
     
         34 - 36 . (canceled)
