Method and apparatus for implementing high speed business measurement between systems

Abstract

The invention provides a method for realizing measurement among systems under a high-speed service. The method comprises the following steps: receiving effective data sent within continuous idle time windows are received; performing leading zero padding and tailing zero padding on the received effective data; performing sliding synchronous burst detection on the data padded with zero by using training sequence codes, and detecting a base station identification code after obtaining the complete synchronous burst effective data. The invention further provides a device for realizing the measurement among the systems under the high-speed service. By the method and the device, BSIC detection of neighbor cells is carried out by the idle time widows consisting of special time slots, which causesthe terminal to realize neighbor cell measurement among the systems to further complete the switching among the systems when available conventional idle time windows do not exist within a service time slot under the high-speed service.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for realizing inter-system measurement under high-speed services. Background technique [0002] In a mobile communication system, for a single-antenna multi-mode terminal, it is necessary to periodically measure all configured neighboring cells according to protocol requirements in connection mode, so as to realize service handover between different cells or cells with different access technologies. At the same time, for systems without compressed mode, in some high-speed service situations, the idle time window for neighbor cell measurement is very small, and generally only neighbor cell measurement within the system can be completed, so it is difficult to It is required to periodically measure neighboring cells of different systems, that is, in this case, it is impossible to complete service handover between systems. For example, in the TD-SCDM...

Problems solved by technology

At the same time, for systems without compressed mode, in some high-speed service situations, the idle time window for neighbor cell measurement is very small, and generally only neighbor cell measurement within the system can be completed, so it is difficult to It is required to periodically measure the adjacent cells of different systems, that is, in this case, the service handover between systems cannot be completed

For example, in the TD-SCDMA system, if the terminal is doing high-speed services, such as 2.8Mbps HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access) services or UL (uplink) 384kbps / DL (downlink) 384kbps services, the current Only TS0, DwPTS (Downlink Pilot Timeslot, downlink pilot time slot), GAP (guard time slot) and UpPTS (Uppiink Pilot Timeslot, uplink pilot time slot) are left for inter-cell measurement, but these 4 time slots A total of only 950us, and the minimum requirement for the idle time window for GSM cell BSIC (BaseStation Identity Code, base station identification code) detection is 962us, therefore, it is impossible to perform synchronization detection between GSM cells, at most only for GSM neighboring cells RSSI (Received Signal Strength Indicator, received signal strength indication) measurement, unable to complete the BSIC detection required by the network

[0003] Of course, in the prior art, multi-antenna terminals can be used to process high-speed data services, but the cost of multi-antenna terminals is high, the requirements for digital baseband processors are also high, and the power consumption is large, which is not conducive to improving work efficiency and saving costs.

[0004] At present, in addition to using multi-antenna terminals, there are usually two methods to solve the above problems: one is not to perform inter-system measurement, and the idle time window is only used for the measurement of neighboring cells within the system, that is, the measurement results of neighboring cells of different systems are not reported Or report the lowest measured value; the other is to only measure RSSI without cell synchronization measurement

However, neither of these two methods can or cannot effectively measure neighboring cells of different systems, thus making it impossible to realize inter-system handover of services in this case. In the case that the current 3G network coverage is not complete, it will be largely affect the quality of service of high-speed data services
