2 Overview of 14.4 kbit/s Circuit Switched Data Carrying data services in the CS domain enables operators to provide more services and increase the revenue.

Huawei GSM BSS supports the transfer of PS services on individual speech channels with a high rate of 14.4 kbit/s for transparent data services or 14.5 kbit/s for non-transparent data services. This rate is higher than the common rate of Circuit Switched Data (CSD) services. In this manner, the user experience is improved.

3-1

3 Technical Description To support this feature, the MSC must support the data service of 14.4 kbit/s on a single timeslot.

At the BSC, select NT14_5K and T14_4K in the Data Service Allowed parameter to support 14.5 kbit/s non-transparent data services and 14.4 kbit/s transparent data services.

When an MS initiates a CSD service at a rate of 14.4 kbit/s, the MSC informs the BSC of the service in the assignment message. The BSC then assigns a TCHF to the MS for the call.
