Embodiment 1

[0031] The present invention provides a method for obtaining the position information of the second switching point, referring to Figure 4 , the method includes:

[0032] 101. Perform cell search, and acquire system information of the serving cell where the repeater resides.

[0033] 102. Decode the above system message to obtain the downlink time slot number of the serving cell where the cell resides.

[0034] 103. According to the downlink time slot number, determine the location information of the second handover point of the serving cell where the camping is located.

[0035] Specifically, the above step 101 may include:

[0036] 101A. Search for a downlink pilot time slot DwPTS.

[0037] Use the power characteristics of the downlink pilot time slot to identify the approximate position of the downlink pilot time slot, that is, the approximate position of the SYNC-DL downlink synchronization code. The existing methods including but not limited to the sliding search powe...

Embodiment 2

[0066] The present invention also provides a wireless terminal module, which can be used to obtain the second switching point position information for a TD-SCDMA-based repeater, refer to Figure 5 , the wireless terminal module includes:

[0067] The search unit 51 is configured to perform a cell search and obtain system information of the resident serving cell where the repeater is located;

[0068] The decoding unit 52 is configured to decode the above-mentioned system message, and obtain the downlink time slot number of the above-mentioned camped serving cell;

[0069] A determining unit 53, configured to determine the location information of the second switching point of the above-mentioned camped serving cell according to the downlink time slot number;

[0070] It should be noted that the wireless terminal module is a TD-SCDMA wireless terminal baseband demodulation module, which may also be referred to as a wireless terminal module for short.

[0071] Specifically, the...

Embodiment 3

[0101] The present invention also provides a repeater 10, such as image 3 As shown, the repeater 10 includes a wireless terminal module 50 for obtaining the position information of the second switching point for the repeater. The wireless terminal module 50 is the wireless terminal module described in Embodiment 2, and its specific Please refer to Embodiment 2 for details, and details are not repeated here.

[0102] Optionally, the wireless terminal module 50 is built in the repeater.

[0103] Further, repeater 10 also includes:

[0104] The monitoring module 20 is configured to adjust the position switch of the second switching point of the repeater in real time according to the location information of the second switching point of the serving cell where the wireless terminal module 50 resides.

[0105] Optionally, the position information of the second switching point above can be expressed in binary form, which needs more than 3 bits to represent, and the wireless termin...

Abstract

The embodiment of the invention relates to the technical field of communication, and discloses a method for acquiring location information of a second switching point, and a wireless terminal module and a repeater. The method comprises that: cell searching is performed, and a system message of a residence service cell in which the repeater is positioned is acquired; the system message is decoded, and a downlink time slot number of the residence service cell is acquired; and the location information of the second switching point of the residence service cell is confirmed according to the downlink time slot number. With application of the embodiment of the invention, the location information of the second switching point can be dynamically acquired in a real-time and accurate way. Compared with methods adopted in the prior art, the method is adaptable to a network of which the second switching point dynamically changes.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for acquiring position information of a second switching point, a wireless terminal module and a repeater. Background technique [0002] In the TD-SCDMA communication system, the length of a TD-SCDMA wireless frame defined by 3GPP is 10ms, and the 10ms wireless frame is divided into two subframes with the same structure, and the length of each subframe is 5ms. Each subframe is divided into 7 regular time slots (also called business transmission time slots) with a length of 675us, Ts0 to Ts6, and 3 special time slots: DwPTS (Downlink Pilot Time Slot, downlink pilot time slot), GP (Guard Period, guard time slot) and UpPTS (Uplink Pilot Time Slot, uplink pilot time slot), the subframe structure is as follows figure 1 shown. Regular time slots are used to transmit user data or control information. Among these 7 conventional time slots, Ts0 is always fixedly used as...
