Embodiment Construction

[0032] The solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0033] When an HSDPA user uses the HS-PDSCH channel for communication connection, the system monitors the signal quality of the active set cell and the monitoring set cell at any time, and determines the user's current optimal cell, and the cell with the best signal quality is the optimal cell. Among them, the active set cells are the set of cells that maintain DPCH channel connection with the user; the monitoring set cells are the set of measurement cells issued by the system to the UE (user terminal), including the adjacent cells of the active set cells. For the measurement of the same-frequency cells, the UE generally uses 1D events according to the signal quality of each cell (1D events are the same-frequency measurement event reports specified in the WCDMA standard. When the optimal cell changes, the UE reports 1D events and triggers 1D events. Th...

Abstract

Present invention discloses a switching control method for high-speed physics down shared channel service cell. It contains A, base station system determining user's current optima cell, B, judging whether said user's high-speed physics down shared channel current service is concordance with current optima cell, if it is not, then switching said service cell to optima cell. Said invention can keep high-speed physics down shared channel in signal best cell as possible, thereby fully utilizing high-speed down grouping accessing technical superiority providing high-speed steady down data transmission to user.

Description

technical field [0001] The invention relates to the field of WCDMA mobile communication, in particular to a switching control method of a serving cell of a high-speed physical downlink shared channel. Background technique [0002] In the fifth edition of WCDMA technology, HSDPA (High Speed ​​Downlink Packet Access) technology is introduced. It is a modulation and demodulation algorithm proposed to meet the asymmetrical requirements of uplink / downlink data services. It can be used in Without changing the existing WCDMA network structure, the service rate of downlink data can be increased. HSDPA realizes downlink high-speed data transmission by adopting a series of key technologies such as adaptive modulation and coding (AMC), hybrid retransmission (HARQ), and fast scheduling of base stations. [0003] HSDPA technology adds three channels, which are high-speed physical downlink shared channel (HS-PDSCH) for transmitting data information in the downlink, high-speed shared cont...
