Problems solved by technology

In this way, the uplink information transmitted by the terminal using the HARQ method of the original cell cannot be demodulated in the target cell
[0016] Due to the different capabilities of the two base stations, the uplink information transmitted by the terminal using the HARQ method of the original cell cannot be demodulated in the target cell. When the terminal only supports HSUPA services, a real HSUPA link cannot be established in the target cell when soft handover is performed between the two cells. , the soft handoff cannot be successfully performed, and the activation set update performance requirements cannot be measured in this case

Embodiment Construction

[0040] The present invention needs to set soft handover performance requirements according to the ability of the cell to support HSUPA services, and perform soft handover performance evaluation on the soft handover behavior of the terminal. The soft handover performance requirements of the terminal usually include: links supported by the terminal at the same time, active set update, data streaming performance. The present invention can set one or more of the links supported by the terminal at the same time, the update of the active set, and the performance of the data flow according to the ability of the cell to support the HSUPA service. Here, the ability of the cell to support the HSUPA service includes: the base station has the chase only capability, the base station has the IR only capability, and the base station has the chase+IR capability.

[0041] When setting the links supported by the terminal at the same time according to the ability of the cell to support HSUPA ser...

Abstract

By representing the cell's supporting capability to HSUPA service in the requirement of soft-switch performance, the consistence between soft-switch performance estimation result and the soft-switch behavior is kept so as to be capable of accurately estimating the soft-switch performance of the terminal. The invention provides multi approaches for setting the requirement of soft-switch performance, which can be used in all situations occurring in the soft-switch process.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a soft handover performance evaluation method supporting HSUPA and a mobile terminal. Background technique [0002] UMTS (Universal Mobile Telecommunications System) is a third-generation mobile communication system that adopts WCDMA (Wideband Code Division Multiple Access) air interface technology. UMTS is mainly developed in the WCDMA / GSM global standardization organization 3GPP. [0003] With the development of third-generation mobile communication technology, people's demand for mobile communication is no longer satisfied with voice services. Since the third-generation mobile communication system can provide services with higher data rates than the second-generation mobile communication system, therefore, A large number of multimedia services emerge, such as video telephony, picture uploading, high-speed Internet browsing and other services. In order to enhance...
