Embodiment Construction

[0027] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Based on the requirement of inter-system measurement in connection state stipulated by the protocol, that is (1) use the frame (Search Frame) without BSIC confirmation to perform TD measurement in GSM / GPRS connection mode. That is, if the network sends the parameter '3G_SEARCH_PRIO', 3G measurement is required, and the UE can use 25 idle frames in 13s to perform TD measurement in GSM / GPRS connection mode; (2) support the measurement of 64 inter-RAT cells , up to 3 TDD (time division duplex) frequency points, and a maximum of 32 cells on a TDD frequency point. According to the analysis of "idle frame" and "idle time slot" in the GSM / GPRS connection mode, it can be known that there is one idle frame every 26 frames; the idle window around the idle frame is 10 time slots.

[0029] The present invention realizes that the flow process of ...

Abstract

The invention discloses a method for completing TD neighbor measurement based on a GSM idle frame, comprising the following steps: A. searching TD system timing with the GSM idle frame; B. according to the TD system timing, computing the observation time difference OTD of a subdistrict to be measured; and C. receiving the midamble correlative data of the subdistrict with the idle frame, and computing the receiving signal code power of the subdistrict under a frequency point. Based on the measurement request of a protocol, the method analyzes GSM multiframe structure, gives a specific realizing method for measuring the TD neighbor under a GSM/GPRS connection state based on an Idle frame with the idle frame appointed by the protocol, and effectively meets a real-time requirement, namely, the TD measurement is completed within 3s.

Description

technical field [0001] The present invention relates to GSM (Global System For Mobile Communications, Global Mobile Communications) / GPRS (General Packer Radio Service, General Radio Packet Service) connection state based on Idle frame (idle frame) to complete TD (Time Division, time division) neighboring cell measurement Technical field, the present invention specifically relates to a method for completing TD neighbor cell measurement based on idle frames. Background technique [0002] Single antenna is the same radio frequency channel to be time-division multiplexed between TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) and GSM mode; in addition, the key to realize dual-mode is that the terminal When staying in any mode, it is necessary to regularly measure the parameters related to neighboring cells in another mode, and perform cell reselection and handover as needed. In order to realize dual-mode and double-cut, the inter-system measurement of GSM / TD-...
