ADAPTIVE R99 AND HSPA LINK DIVERSITY FOR COVERAGE AND CAPACITY ENHANCEMENT OF CIRCUIT-SWITCHED CALLS |
摘要 |
<p>A system and methodology that facilitates adaptive link diversity for enhanced coverage and capacity during user data communication in a UMTS (Universal Mobile Telecommunications System) is provided. Specifically, current radio conditions associated with the user data are monitored and analyzed. Moreover, a switching and/or concurrent transport mechanism is implemented for communication between a NodeB and UE (User Equipment), when the current radio conditions change beyond a predefined level. In particular, a CS (Circuit Switched) over HSPA (High Speed Packet Access) connection is reconfigured to an R99 (Release 99) CS connection, or a concurrent R99 CS connection is provided along with the CS over HSPA connection, when detected that radio conditions have degraded beyond a predefined threshold. In one aspect, the selection between switching to a new transport mechanism and, adding a concurrent transport mechanism is based on an analysis and/or operator defined conditions.</p> |
