Measuring method for inter-system and wireless network controller thereof

Abstract

The embodiment of the invention discloses a measuring method for an inter-system. The method comprises the following steps that time slot allocation is carried out on an idle interval used for measurement by a wireless network controller to obtain allocation parameters of the idle interval used for measurement; the allocation parameters of the idle interval used for measurement include a start time slot and an end time slot of the idle interval used for measurement, and the time span of the idle interval used for measurement is shorter than the time span of the idle interval of the system; and the allocation parameters of the idle interval used for measurement are sent to a user terminal by the wireless network controller, so that the inter-system is measured within the time interval between the start time slot and the end time slot by the user terminal according to the allocation parameters of the idle interval used for measurement. The embodiment of the invention also discloses a wireless network controller. According to the method disclosed by the invention, the system idle interval and the usable time of front and rear subframes can be increased, and the business rate of the user terminal and the handling capacity of a communication system are improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a measurement method of different systems and a wireless network controller thereof. Background technique [0002] In a wireless communication system (such as a TD-SCDMA system), the system requires user terminals to be able to switch to other systems such as LTE. In order to realize handover between systems, the user terminal needs to measure the signal quality of the cell of the handover target system before handover, that is, the user terminal needs to measure the different system. In the prior art, the user terminal periodically vacates a system idle interval of 1 frame (i.e. 10ms) every 4 frames (i.e. 40ms) or 8 frames (i.e. 80ms) to measure different systems. In the 10ms system idle interval , the user terminal only measures the different systems and does not perform service scheduling with the base station. [0003] In the long-term research and development,...

Problems solved by technology

[0003] The inventors of the present application have found in the long-term research and development that, on the one hand, for services such as HSDPA, HSUPA, and HSPA, the user terminal needs to feed back the ACK information of the second subframe before it to the base station on the HS-SICH of the current subframe, but in the current In the state-of-the-art configuration method for inter-system measurement, since the system idle interval itself is idle for 2 subframes, the 2 subframes (10ms) before the system idle interval and the 1 subframe (5ms) after the system idle interval cannot perform HSDPA Waiting for business scheduling, for the user terminal, an unavailable time of 15ms is added within a period of 40ms or 80ms; Or 6 ms of 80 ms can be measured. In the prior art, there is redundancy in the system idle interval of 10 ms. The configuration method of different system measurement in the prior art seriously affects the normal business scheduling, user terminal rate and throughput of the communication system.
