Problems solved by technology

Since the IUB port is often used for measurement, when a Node B (Node B) configures multiple multi-carrier frequency cells, numerous and too frequent measurement report messages will waste a large amount of IUB port bandwidth and affect the CPU processing capacity

Embodiment Construction

[0021] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] As shown in Figure 1, the process for RNC to initiate a common measurement in a multi-carrier cell is:

[0023] Step S102: RNC sends a public measurement initialization message to Node B, and the initialization message includes the measurement range of this measurement;

[0024] When the RNC decides to initiate a public measurement in a multi-carrier cell, the RNC sends a public measurement initialization message to the Node B, and specifies the scope of this measurement by filling in frequency information and time slot information according to actual needs. For carrier frequency level measurement, when RNC decides that the measurement range is all carrier frequencies, RNC does not carry carrier frequency information; when RNC decides that the measurement range is a specific carrier frequency, RNC fills in the frequency information of the...

Abstract

The invention discloses a public measurement method suitable for TD-SCDMA system, which comprises the following steps: 1. RNC sends a public measurement initialization message to NodeB, and the initialization message includes the measurement range of this measurement; 2. After the NodeB receives the public measurement initialization request, it starts the public measurement according to the measurement scope specified by the RNC, and returns a public measurement initialization response message to the RNC after the public measurement is started successfully; 3. The NodeB sends a public measurement report message to the RNC, and the measurement The report message carries the measurement results of all relevant measurements within the range specified by the RNC; 4. The RNC receives the public measurement report message from the NodeB, and extracts each carrier frequency and / or time slot according to the carrier frequency and / or time slot information in the message The specific measurement results of the gap. The method of the invention greatly reduces the public measurement report messages of the IUB port, remarkably reduces the processing load of the RNC, NodeB and CPU and the occupation of the transmission bandwidth of the IUB port, and improves the system performance and stability.

Description

Technical field [0001] The invention relates to the field of TD-SCDMA wireless communication, in particular to an optimization method for the initiation and reporting process of the public measurement of IUB interface cells in the TD-SCDMA system. Background technique [0002] In the TD-SCDMA system, in order to solve the problem of limited code channels, multi-carrier technology is introduced, which improves the capacity and acceptance of a single cell in the system. Among them, a multi-carrier cell means that multiple carriers are provided in one cell, and each cell uses one of the carriers as the main carrier. The system provides BCH (broadcast channel), UpPCH (uplink pilot channel), and DwPCH (downlink pilot channel) on the main carrier. Frequency channel) and other common channels are used for system information broadcasting and terminal access, while on other carriers (hereinafter referred to as auxiliary carriers), only service channels are provided. After the introduction...
