Communication system including a femtocell and communication method thereof

摘要

The communication system comprises a base station (BS), a femtocell and a core network. The femtocell deployed within the signal coverage of the BS establishes a first wired connection with an internet service provider (ISP) network and a first wireless connection with a user equipment (UE). The core network establishes a second wired connection with the ISP network and a third wired connection with the BS. The core network is configured to determine that a voice data transmission service is about to be provided to the UE, and transmit a first radio access bearer (RAB) setup request message to the BS to enable the BS to establish a second wireless connection with the femtocell according to the first RAB setup request message so that the UE performs a voice data transmission with the core network via the first wireless connection, the second wireless connection and the third wired connection.

1. A communication system, comprising:
a base station (BS), having a signal coverage; a femtocell, being deployed within the signal coverage, establishing a first wired connection with an internet service provider (ISP) network, and establishing a first wireless connection with a user equipment (UE); and a core network, establishing a second wired connection with the ISP network, establishing a third wired connection with the BS, and being configured to determine that a voice data transmission service is about to be provided to the UE, and transmit a first radio access bearer (RAB) setup request message to the BS when the voice data transmission service is about to be provided to the UE to enable the BS to establish a second wireless connection with the femtocell according to the first RAB setup request message so that the UE performs a voice data transmission with the core network over the BS and the femtocell via the first wireless connection, the second wireless connection and the third wired connection; wherein the core network further performs a non-voice data transmission with the UE over the ISP network and the femtocell via the first wireless connection, the first wired connection and the second wired connection.
