Definitions
- the present invention relates to wireless communication technologies, and in particular, to a control method and system for a compressed mode. Background technique
- GSM Global System Mobile
- WCDMA Wideband Code Division Multiple Access
- E-UTRA Enhanced Global Radio Access
- the UTRAN system focuses on carrying ultra-high speed packet domain services.
- the above-mentioned handover process caused by the inter-system mobility management requires measurement of the target system and the target carrier frequency in the prior handover preparation phase to accurately perform the handover decision.
- the compression mode plays an important role in the inter-carrier and inter-system measurement.
- the terminal can measure the non-serving carrier frequency and the carrier frequency of other systems without configuring the dual receiver.
- a receiver terminal from the third-generation WCDMA system to the area covered by the second-generation GSM system, can only use the compressed mode for inter-system measurements.
- the compressed mode can also be used for terminal access to multiple carrier coverage areas of third-generation WCDMA systems.
- the terminal in compressed mode, the terminal can measure another non-serving carrier frequency without losing it. Any data transmitted on the service carrier frequency.
- the compression mode is defined as a transmission mode in which data transmission is compressed in the time domain to produce a transmission gap.
- the receiver of the terminal can use this transmission gap to tune to another carrier frequency for measurement.
- the transmission gap is typically determined by a description of the transmission gap pattern sequence.
- Each set of transmission gap pattern sequences is uniquely identified by the transmission gap pattern sequence identifier and can only be used for a transmission gap pattern sequence measurement application, that is, frequency division duplex measurement, time division duplex measurement,
- GSM carrier received signal strength indication Receiveived Signal Strength Indication
- GSM base station identification color code initial identification GSM base station identification color code recognition reconfirmation
- multi-carrier frequency measurement E-UTRA measurement, and the like.
- the transmission gap pattern sequence includes two alternate transmission gap patterns, namely a transmission gap pattern 1 and a transmission gap pattern 2, and each transmission gap pattern is One or two transmission gaps are provided within one transmission gap pattern length. Further, each transmission gap pattern sequence further includes a transmission gap connection frame number (CFN) indicating a start/stop compression mode time, and a transmission gap pattern sequence. The number of repetitions, etc., are determined based on the transmission gap pattern sequence measurement usage.

- the terminal In order to increase system capacity and user throughput, the compression mode starts later, the better, and the compression mode lasts as short as possible.
- the terminal In the prior art, the terminal generally controls the start or stop of the compressed mode. For example, the terminal determines that the quality of the wireless signal of the current serving cell is not good, and may need to prepare to switch to the inter-carrier/inter-system neighboring area, and then initiate the compressed mode. When the terminal determines that the wireless signal quality of the current serving cell is good or has obtained the measurement result, the compression mode is stopped. Correspondingly, when the terminal decides to start/stop the compression mode, it will inform the node B of the start/stop transmission gap pattern sequence.
- the existing compression mode control method has the following problems: When a large number of terminals appear in one cell, the available resources of the cell may not be sufficient to guarantee the quality of service of all services of all terminals, resulting in congestion or overload.
- a low-cost method for coping with congestion or overloaded cells is to balance services to The low-load neighboring area (that is, the load balancing mechanism), and the wireless signal is not problematic when the current serving cell is too high, and the wireless signal is usually not detected in the current serving cell. It is better.
