DCFirst Claim
1. A system for signal processing in a mobile communication system, the system comprising:
- a base transceiver station (BTS) for communicating configured to communicate a call signal with a mobile terminal selected from plural a plurality of mobile terminals;
a base station controller (BSC) for controlling configured to control wireless communication between the BTS and the mobile terminal;
a BSC matching unit (BSCMU), being connected to the BSC through a first dedicated line, configured to convert a first dedicated-line data signal transmitted by the BSC into a first set of IP packets and convert a second set of IP packets into a second dedicated-line data signal to be transmitted to the BSC; and
a BTS matching unit (BTSMU), being connected to the BTS through a second dedicated line, configured to convert the first set of IP packets into the first dedicated-line data signal to be transmitted to the BTS and convert the second dedicated-line data signal transmitted by the BTS into the second set of IP packets to be transmitted to the BSCMU, wherein the BTSMU is further configured to communicate the IP packets with the BSCMU via an IP network.

Abstract
Various embodiments of the invention relate to a low-cost network system that can reduce the network cost by connecting a base station controller (BSC) with a base transceiver station (BTS) by the use of matching units that match an E1/T1 line to an IP line. In one embodiment, the system comprises a BSC matching unit (BSCMU) and a BTS matching unit (BTSMU). The BSCMU, connected to the BSC through a first dedicated line, converts a first dedicated-line data signal, received from the BSC, into a first IP signal to be transmitted through an IP line and converts a received second IP signal into a second dedicated-line data signal to be transmitted to the BSC. The BTSMU, connected to the BTS through a second dedicated line, converts the first IP signal into the first dedicated-line data signal to be transmitted to the BTS and converts the second dedicated-line data signal, received from the BTS, into the second IP signal.
