Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] To obtain the time base relationship of different communication modes, it is necessary to use registers to latch the time base difference between different modes, and then obtain the time base difference by accessing the registers to further calculate the time base relationship between different communication modes. Therefore, the latching and acquisition of the time base difference is a preparatory step for calculating the time base relationship, and the latching and acquisition process of the time base difference of the present invention are as follows:

[0031] 1) Select one of the various communication modes as the reference mode, and the rest as non-reference modes;

[0032] 2) For each non-reference mode, configure the first register an...

Abstract

The method includes steps: (1) at time of starting up frame in reference communication mode (RCM), using first register to latch time base difference between RCM and non-RCM; at time of starting up frame in non-RCM, using second register to latch time base difference (TBD) in the first register; (2) based on frame number n in RCM at sampling time, frame number m in non-RCM, difference value Y of frame length between RCM and non-RCM, and relation of big and small between latched value in first register and latched value in second register to determine corresponding relation between TBD represented by latched value in second register and frame number at sampling time; based on the corresponding relation to obtain time base value. The invention lists all five corresponding relations between TBD and frame number, and also discloses method for determining each corresponding relation. The invention can decide time base relation between two modes precisely and smartly.

Description

technical field [0001] The present invention relates to a time-based relationship acquisition technology in multi-mode mobile communication, in particular to a time-based relationship acquisition method and an acquisition device in multi-mode mobile communication. Background technique [0002] With the development of communication technology, TD-SCDMA (Time Division Synchronous Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), and CDMA2000 (Qualcomm's Code Division Multiple Access standard) in the third generation mobile communication technology (3G) ) will be networked one after another. Therefore, in order to meet the needs of users for different network modes, mobile communication technology is also moving to dual-mode (such as GSM (Global System for Mobile) / TDD-LCR (Time Division Duplex Low Chip Rate, which is TD- A version of SCDMA), GSM / WCDMA) and even multi-mode development. [0003] GSM / TDD-LCR dual-mode mobile communication technology ...
