Adaptive R99 and HS PS (high speed packet-switched) link diversity for coverage and capacity enhancement of circuit-switched calls

摘要

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.

a memory to store executable instructions; and a processor, coupled to the memory, that facilitates execution of the executable instructions to perform operations, comprising:
subsequent to a circuit-switched communication session being determined to be established between an access point device and a user equipment via a radio bearer link that is shared by user equipments coupled to the access point device, determining ratio data indicative of a ratio of a first number of data transmissions sent from the access point device to the user equipment, to a second number of data transmissions sent from the user equipment to the access point device during the circuit-switched communication session, andbased on a determination that the ratio data satisfies a defined ratio criterion and retransmission data indicative of a rate at which information has been retransmitted between the user equipment and the access point device satisfies a defined retransmission criterion, reconfiguring the circuit-switched communication session between the access point device and the user equipment via a dedicated radio bearer link.
