时分同步码分多址系统的测量方法及双模终端 Measurement of the TD-SCDMA system and a dual mode terminal

技术领域 FIELD

[0001] 本发明涉及通信领域,特别涉及通信领域中的异系统测量技术。 [0001] The present invention relates to communication field, particularly to inter-system measurement technology in the communication field.

[0002] 背景技术 [0002] BACKGROUND OF THE INVENTION

[0003] 随着通信技术的不断发展,出现了各种类型的无线通信系统,如全球移动通信系统(Global System for Mobile communication,简称“GSM”),宽带码分多址(WidebandCode Division Multiple Access,简称“WCDMA”),时分同步码分多址(Time DivisionSynchronous Code Division Multiple Access,简称"TD-SCDMA,,),微波接入全球互通(Worldwide Interoperability for Microwave Access,简称"WiMAX,,),长其月演进(LongTerm Evolution,简称“LTE”),蓝牙,中国移动多媒体广播(China Mobile MultimediaBroadcasting,简称“CMMB”)等等。 [0003] With the continuous development of communication technology, the emergence of various types of wireless communication systems such as GSM (Global System for Mobile communication, referred to as the "GSM"), Wideband Code Division Multiple Access (WidebandCode Division Multiple Access, referred to as "WCDMA"), TD-SCDMA (Time DivisionSynchronous Code division Multiple access, referred to as "TD-SCDMA ,,), WiMAX (worldwide interoperability for microwave access, referred to as" WiMAX ,,), its length May Evolution (LongTerm Evolution, referred to as "LTE"), Bluetooth, China mobile multimedia broadcasting (China mobile MultimediaBroadcasting, referred to as "CMMB") and so on.

[0004] 其中,TD-SCDMA的子帧结构如图1所示,1个IOms的TD-SCDMA帧可分为2个5ms的子帧,每个5ms的子帧包含7个时隙(时隙0至时隙6)以及下行导频时隙DwPTS、保护间隔GP、上行导频时隙UpPTS。 [0004] where, TD-SCDMA subframe structure shown in Figure 1, a IOms the TD-SCDMA frame may be divided into two sub-frames of 5ms, each 5ms sub-frame includes seven time slots (time slots time slot 0 to 6) and the downlink pilot time slot DwPTS, guard interval GP, uplink pilot time slot UpPTS.

[0005] 目前,许多终端(如手机)都可支持两种无线系统(或无线标准),如既支持GSM又支持TD-SCDMA。 [0005] Currently, many terminals (such as mobile phones) can support two wireless systems (standard or wireless), such as support for both GSM and supports TD-SCDMA. 这种支持两种无线系统的终端通常称为双模终端。 This system supports two wireless terminals are typically referred to as a dual-mode terminal. 关于移动终端支持多种无线系统的技术方案可参见专利号为11136547的美国专利。 About mobile terminal supports multiple aspect wireless system may refer to U.S. Patent No.'s 11136547. 为了支持两种系统的模式切换,必须要支持异系统的测量。 In order to support two modes of switching of the system, we must support inter-system measurement.

[0006] 由于目前当GSM/TD-SCDMA双模终端处于GSM模式下时,GSM网络只广播TD-SCDMA频点,而不广播TD-SCDMA小区的方式,因此双模终端主要通过以下两种方案在GSM网络中发起对TD-SCDMA系统的测量: [0006] When due to the current GSM / TD-SCDMA dual-mode terminal is in GSM mode, GSM network broadcasts only TD-SCDMA frequency without broadcasting TD-SCDMA cell, thus a dual mode terminal through the following two schemes initiating measurement of the TD-SCDMA system in the GSM network:

[0007] 方式一:根据TD-SCDMA频点进行小区的盲搜即该频点下midamble (训练序列码)的确认,并要进行周期性的确认,根据确认的训练序列码进行接收信号码功率(ReceivedSignal Code Power,简称“RSCP”)的测量; [0007] Method 1: for the blind according to the TD-SCDMA cell frequency point of the frequency Instant confirmation the midamble (the training sequence code) and to periodically confirm reception signal code power according to the training sequence code confirmation (ReceivedSignal Code Power, referred to as "RSCP") is measured;

[0008] 方式二:对TD-SCDMA频点进行接收信号场强指示(Receiving SignalStrengthhdicator,简称“RSSI”)的测量而非RSCP的测量,因此无需确认各频点的训练序列码。 [0008] Second way: frequency of the TD-SCDMA reception signal strength indication (Receiving SignalStrengthhdicator, referred to as "RSSI") rather than measuring the RSCP measurements, there is no need to confirm the training sequence code for each frequency point.

[0009] 然而,本发明的发明人发现,对于方式一而言,由于根据目前中国移动的要求,在GSM系统下配置的TD-SCDMA系统频点个数最多为9个,要进行所有频点的midamble码检测,以及周期性的midamble码的确认,因此对终端的功耗增加是巨大的。 [0009] However, the present inventors found that, for an embodiment, since according to the current requirements of China Mobile, TD-SCDMA system in the GSM system configured frequency point number of a maximum of 9, all the frequencies to be detecting the midamble code, the midamble code and confirmed periodically, thus increasing the terminal power consumption is huge. 对于方案二而言,虽然通过采用RSSI的方式测量TD-SCDMA系统会带来实现简单,功耗低等优点,但是,以RSSI的方式实现的测量不够准确,在发生异系统间的模式切换时,因为测量的不准确性容易导致切换失败,以及各类测量精度的测试中不能满足测试需求。 For Option II, although the measurement by means of TD-SCDMA system will bring RSSI using simple, low power consumption, but the manner in RSSI measurement is not accurate enough, a mode switch between different phylogenetic because it is not easy to measure the accuracy of the switch fails, and a variety of measurement accuracy of the test can not meet the test requirements.

发明内容 SUMMARY

[0018] 选取模块,用于将RSSI测量模块测量到的各TD-SCDMA频点的RSSI值分别与第一门限值进行比较,选取RSSI值大于第一门限值的TD-SCDMA频点,如果不存在RSSI值大于第一门限值的TD-SCDMA频点,则选取模块等待接收下一个周期内RSSI测量模块测量到的各TD-SCDMA频点的RSSI值,其中,第一门限值为用于判断TD-SCDMA频点所对应的小区信号是否满足异系统切换要求的门限值; [0018] selection module, for the RSSI values ​​measured by the RSSI measuring module TD-SCDMA each frequency point are compared with a first threshold value, select the TD-SCDMA frequency RSSI value is greater than the first threshold value, If TD-SCDMA frequency RSSI value is greater than the first threshold value does not exist, the RSSI value selection module waits to receive the next cycle of the RSSI measurement module measures the TD-SCDMA each frequency point, wherein the first threshold value determining a cell for TD-SCDMA signal corresponding to the frequency point satisfies the requirements of the inter-system handover threshold;

[0022] 本发明实施方式与现有技术相比,主要区别及其效果在于: [0022] Embodiment of the present invention compared to the prior art, the main differences and effects in that:

[0023] 双模终端在周期性地发起对TD-SCDMA系统的测量时,先测量所有TD-SCDMA频点的RSSI,通过将各TD-SCDMA频点的RSSI值与一个用于判断小区信号是否满足异系统切换要求的第一门限值做比较,选取出RSSI值高于第一门限值的TD-SCDMA频点。 [0023] When the dual mode terminal periodically initiating measurement of the TD-SCDMA system, first of all measuring the RSSI frequency of TD-SCDMA, the RSSI value of each of TD-SCDMA with a frequency signal for determining whether the cell inter-system handover to meet the requirements of the first threshold value for comparison, the TD-SCDMA selected frequency RSSI value is above the first threshold value. 由于在TD-SCDMA系统中,RSSI的测量结果大于等于RSCP的测量结果(这里是指对TD-SCDMA的训练序列所在时隙进行测量,即对时隙0进行测量,以下同),因此在需要进行RSCP测量的TD-SCDMA频点下的小区应当是信号满足切换要求(即大于第一门限值)的情况下,信号满足切换要求的TD-SCDMA频点的RSSI也必定会大于第一门限值。 Since the TD-SCDMA system, the RSSI measurements greater than or equal RSCP measurements (here refers to the time slot where the training sequence is measured TD-SCDMA, i.e. slot 0 to be measured, hereinafter the same), and therefore need the RSCP measured for the cell of the frequency should be a TD-SCDMA to meet the switching request signal (i.e., greater than a first threshold value), the switch to meet the requirements of the RSSI signal TD-SCDMA frequency must also be greater than the first threshold limit. 对所选取的频点进行训练序列码的检测、RSCP的测量,并根据RSCP的测量结果进行TD-SCDMA小区的同步维持。 Of the selected frequency is detected, measured RSCP training sequence code, and synchronization maintenance TD-SCDMA cell of RSCP measurement result. 由于并非是对所有TD-SCDMA频点进行训练序列码的搜索、RSCP的测量,而是对过滤后的TD-SCDMA频点进行训练序列码的检测、RSCP的测量,因此可以大大降低搜索TD频点的个数,从而有效节省了终端的功耗。 Since a search is not the training sequence code, the RSCP measurement of all TD-SCDMA frequency, but the frequency of TD-SCDMA to detect the filtered training sequence code, the RSCP measurements, it is possible to greatly reduce the frequency search TD the number of points, thereby effectively saving the power consumption of terminals. 通过将测量分级,将超过门限的TD-SCDMA频点的测量优先级变高,对高优先级的频点进行RSCP测量。 By classifying the measurement, the measurement exceeds a threshold TD-SCDMA frequency becomes high priority, high-priority frequency point RSCP measurements. 由于重选的或者切换异系统(指TD-SCDMA) 最重要的部分就是要保证最强的小区能够经常而且准确地被测量,因此通过对优先级高的频点进行训练序列码的检测、RSCP测量,能够在节省功耗的同时,有效保证TD-SCDMA系统测量的准确度。 Since reselection or inter-system handover (of TD-SCDMA) the most important part is to ensure that the strongest cell can be measured frequently and accurately, and therefore by detecting the training sequence code of a frequency higher priority, the RSCP measurements, it is possible to save power consumption at the same time, effectively guarantee the accuracy of measurement of TD-SCDMA system. 另外,由于通过周期性地对TD-SCDMA系统进行测量,能够确保TD-SCDMA的同频小区能够被及时发现。 Further, since the periodically measured TD-SCDMA system, TD-SCDMA is possible to ensure the same frequency cell can be identified.

[0024] 进一步地,第一门限值为系统消息中广播的重选门限值。 [0024] Further, the first threshold is the threshold value reselection of the broadcast system message. 由于异系统的测量目的主要就是保证异系统间的切换能顺利执行,因此以系统消息中广播的重选门限值(如GSM的系统消息2qUater中广播的重选门限值)作为第一门限值,可以保证所选取的需要进行RSCP测量的小区是信号满足切换要求的小区。 Since the main purpose of measurement is to ensure inter-system handover between different systems can be smoothly performed, therefore reselection threshold value (e.g., GSM system message reselection threshold 2qUater in broadcast) system information broadcast in the first gate value, can be selected to ensure the required RSCP measured cell is a cell signal satisfies the handover requirements.

[0025] 进一步地,对未选取的各TD-SCDMA频点分别进行RSSI的测量,如果测量到的RSSI值大于第二门限值,则对大于第二门限值的RSSI值所对应的TD-SCDMA频点,进行训练序列码的检测,根据检测到的训练序列码对该TD-SCDMA频点下的小区进行RSCP的测量,并根据RSCP的测量结果进行TD-SCDMA小区的同步维持。 [0025] Further, each of the TD-SCDMA unselected frequency measurement RSSI, respectively, if the measured RSSI value is larger than a second threshold value, then the RSSI value is greater than the second threshold value corresponding to the TD -SCDMA frequency, detecting training sequence code, the measurement of RSCP in the TD-SCDMA cell frequency point according to the detected training sequence code, and synchronization maintenance TD-SCDMA cell of RSCP measurement result. 测量RSSI的频点仍有机会转为RSCP测量,可以有效避免应搜索的TD-SCDMA频点的遗漏。 Measuring the frequency of RSSI still have a chance into RSCP measurements can effectively avoid missing TD-SCDMA should search frequency point.

[0026] 其中,第二门限值大于或等于对选取的各TD-SCDMA频点下的小区测量到的RSCP值中的最大值,并且大于或等于第一门限值。 [0026] wherein the second threshold value is greater than or equal to the maximum value of the cell RSCP measured for each of the TD-SCDMA selected frequency points, and greater than or equal to the first threshold value. 由于在TD-SCDMA系统中,RSSI的测量结果大于等于RSCP的测量结果,也就是说,如果TD-SCDMA频点A的RSSI小于TD-SCDMA频点B的某个小区的RSCP,则A频点下所有的TD小区的RSCP必然小于频点B下该小区的RSCP。 Since the TD-SCDMA system, the RSSI measurements greater than or equal RSCP measurement result, that is, if TD-SCDMA RSSI is smaller than the frequency A TD-SCDMA RSCP certain frequency cell B, then A frequency TD all the cells must be smaller than the frequency RSCP RSCP at the B cell. 因此测量RSSI的频点转换为RSCP测量,需要满足的条件是测量的RSSI值大于测量到的RSCP值中的最大值,并且大于第一门限值,从而有效控制了终端用于测量TD-SCDMA系统的功耗。 Therefore the RSSI measured frequency is converted into RSCP measurement condition to be met is greater than the maximum measured RSSI value measured RSCP value and greater than a first threshold value, thereby effectively controlling the terminal for measuring the TD-SCDMA system power consumption.

[0027] 进一步地,对TD-SCDMA频点的下行同步码的检测需要执行M次,M为大于或等于1的整数;根据检测到的下行同步码,对相应的训练序列码的检测也需要执行P次,为大于或等于1的整数。 [0027] Furthermore, the detection of TD-SCDMA frequency downlink synchronization code needs to be performed M times, M being integer greater or equal to 1; according to the detected downlink synchronization code, detecting the respective training sequence code is also required P execution times, an integer greater than or equal to 1. 可有效保证测量的准确性。 Can effectively ensure the accuracy of measurement.

具体实施方式 Detailed ways

[0032] 在以下的叙述中,为了使读者更好地理解本申请而提出了许多技术细节。 [0032] In the following description, in order to enable the reader to better understand the application and made many technical details. 但是,本领域的普通技术人员可以理解,即使没有这些技术细节和基于以下各实施方式的种种变化和修改,也可以实现本申请各权利要求所要求保护的技术方案。 However, those of ordinary skill in the art can be appreciated, without these technical details and various changes and modifications based on the following embodiments, the present application may also be implemented as claimed in claim various technical solution.

[0033] 为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明的实施方式作进一步地详细描述。 [0033] To make the objectives, technical solutions, and advantages of the present invention will become apparent in conjunction with the following drawings, embodiments of the present invention will be described in further detail.

[0034] 本发明第一实施方式涉及一种时分同步码分多址系统的测量方法,具体流程如图2所示。 [0034] The first embodiment of the present invention relates to a method for measuring the TD-SCDMA system, the specific procedure shown in FIG.

[0035] 在步骤201中,双模终端利用能量窗的方式获取TD-SCDMA下行帧的位置。 [0035] In step 201, the dual-mode terminal using energy windows way to obtain a position downstream TD-SCDMA frame.

[0036] 接着,在步骤202中,双模终端利用在步骤201中获得的TD-SCDMA下行帧的位置,对所有频点进行一次能量检测,即对所有广播的TD-SCDMA频点进行TSO (时隙0)的midamble位置的RSSI能量检测。 [0036] Next, in step 202, the position of the dual-mode terminal uses a downlink TD-SCDMA frame obtained in step 201, once all the energy detection frequencies, i.e. for all TSO TD-SCDMA radio frequency ( RSSI energy slot 0) of the position detecting midamble. RSSI的测量在现有技术中已能实现,在此不再赘述。 RSSI measurements have been able to achieve in the prior art, which is not repeated herein.

[0037] 接着,在步骤203中,将测量到的各TD-SCDMA频点的RSSI值分别与第一门限值进行比较,选取RSSI值大于第一门限值的TD-SCDMA频点。 [0037] Next, at step 203, the measured RSSI values ​​to each of the TD-SCDMA frequency points are compared with a first threshold value, select the TD-SCDMA frequency RSSI value is greater than the first threshold value. 其中,第一门限值为用于判断TD-SCDMA频点所对应的小区信号是否满足异系统切换要求的门限值,如第一门限值为GSM 系统消息2qUater中广播的重选门限值(即TDD_0FFSET的门限值)。 Wherein the first determination threshold value for TD-SCDMA cell frequency point signal corresponding to the inter-system handover meets the threshold requirement, such as a GSM system, a first threshold value broadcast message 2qUater reselection threshold value (i.e., the threshold TDD_0FFSET). 如果没有超过第一门限值的TD-SCDMA频点(即选取的频点个数为0),则在等待一段时间(如步骤203' )后回到步骤202,即等待一个周期再进行所有频点的RSSI测量。 If there is no TD-SCDMA frequency exceeds a first threshold value (i.e., the number of the selected frequency is 0), then at a later time (step 203 ') returns to step 202, i.e., a waiting period then all RSSI measurement frequency points. 如果选取的频点个数大于0,则进入步骤204。 If the number of selected frequency is greater than 0, the process proceeds to step 204.

[0038] 接着,在步骤204中,利用相关的方法对所选取的频点(即超过门限的TD-SCDMA 频点)逐一进行32个SYNC_DL(下行同步码)的检测,为保证准确性,此步骤做M次,M > =1。 [0038] Next, in step 204, using an associated method for the selected frequency (i.e., exceeding the threshold TD-SCDMA frequency) one by one 32 SYNC_DL (downlink synchronization code) is detected, to ensure the accuracy, this step done M times, M> = 1. 对TD-SCDMA频点进行SYNC_DL的检测属于现有技术,在此不再赘述。 Detection of TD-SCDMA SYNC_DL frequency point belongs to the prior art, are not repeated here.

[0039] 接着,在步骤205中,对于每个超过第一门限值的TD-SCDMA频点,如果找到相应的SYNC_DL (设为N个),则通过N个SYNC_DL确定N个相对应的N个midamble码,为保证准确性,此步骤做P次,P > = 1。 [0039] Next, in step 205, for each of the TD-SCDMA frequency exceeds a first threshold value, and if it finds the corresponding SYNC_DL (set of N), N number of SYNC_DL determined by the number N corresponding to N a midamble code, to ensure the accuracy, this step is done with P, P> = 1.

[0040] 接着,在步骤206中,根据检测到的训练序列码对该训练序列码所对应的TD-SCDMA频点进行接收信号码功率RSCP的测量,并根据RSCP的测量结果进行TD-SCDMA小区的同步维持。 [0040] Next, in step 206, the measurement is received signal code power RSCP according to the TD-SCDMA to detect the frequency of the training sequence code corresponding to a training sequence code, and TD-SCDMA cell RSCP measurement result of coherency is maintained. 也就是说,对已经确认midamble的TD-SCDMA频点进行RSCP测量,并同时根据RSCP的测量结果进行TD-SCDMA小区的同步维持。 That is, has confirmed that the TD-SCDMA midamble frequency point RSCP measurement, while maintaining the synchronization of the TD-SCDMA cell RSCP of the measurement results. 对TD-SCDMA小区的同步维持与现有技术相同,如可通过接收下行导频时隙实现与TD-SCDMA小区的同步,在此不再赘述。 Synchronization of TD-SCDMA cells to maintain the same prior art, as may be achieved by receiving a downlink pilot time slot synchronization with TD-SCDMA cell, are not repeated here.

[0041] 周期性重复上述步骤202至206,以确保超过重选门限值的TD频点能够进行midamble码的及时更新。 [0041] periodically repeating the above steps 202 to 206, to ensure that the threshold value is exceeded reselection TD update frequency can be midamble code. 由于在现有协议中规定最迟在30s内测量到TD-SCDMA小区,因此在本实施方式中,将周期设置为30秒,能更好地与现有技术相兼容。 Since the latest measured in the TD-SCDMA cell in the existing protocol specified in the 30s, in the present embodiment, therefore, the period is set to 30 seconds, to better compatibility with the prior art.

[0042] 由于重选或者切换异系统QgTD-SCDMA)最重要的部分就是要保证最强的小区能够经常而且准确地被测量。 [0042] Since the reselection or handover most important part of the inter-system QgTD-SCDMA) is to ensure that the strongest cell can be measured frequently and accurately. 那么在众多频点下,就需要分优先级的策略。 So in many frequency points, on priority policy needs points. 由于根据目前中国移动的要求,在GSM系统下配置的TD-SCDMA系统频点个数最多为9个,因此必定会导致众多频点的轮换,因轮换而导致的TD-SCDMA测量周期加长就成为测量控制的重要问题。 Since the current requirements of China Mobile, the number of TD-SCDMA system frequency GSM system arranged in a maximum of 9, so will inevitably lead to numerous rotation frequency, because the resulting rotation of TD-SCDMA measurement period becomes longer important issue control measurements. 因此,分优先级就显得非常必要。 Therefore, prioritize it is very necessary. 在本实施方式中,由于加入了TD重选门限,大大降低了搜索TD-SCDMA频点的个数。 In the present embodiment, since the added reselection threshold TD, greatly reducing the number of search frequency of TD-SCDMA. 由于不需要搜索所有的TD-SCDMA频点的midamble码,因此可有效节省功耗(这主要是因为测量RSCP的开销比测量RSSI的开销大很多,有效的限制测量RSCP的TD频点则会很有效的控制功耗,以及较强频点的测量频率)。 Since no search midamble code all TD-SCDMA frequency points, thus saving power consumption (mainly because of the cost of measuring RSCP much larger than the RSSI measurement overhead, effectively limit the measurement of RSCP TD frequency will be very effective control of power consumption, and measuring the frequency of a strong frequency). 而且,由于在TD-SCDMA系统中,RSSI的测量结果大于等于RSCP的测量结果,因此在需要进行RSCP测量的TD-SCDMA频点应当是信号满足切换要求(即大于重选门限值)的情况下,信号满足切换要求的TD-SCDMA频点的RSSI也必定会大于重选门限值。 Further, since the TD-SCDMA system, the RSSI measurements greater than or equal RSCP measurement results, so the TD-SCDMA frequencies required RSCP measurements should be satisfied switching request signal (i.e., greater than a threshold value reselection) case next, RSSI signal meets the requirements of TD-SCDMA switching frequency must also be greater than the threshold value reselection. 因此通过将测量分级,超过重选门限的TD-SCDMA频点的测量优先级变高,对其进行RSCP测量,从而提高了测量准确度。 Therefore, by measuring the measurement hierarchy, than reselection threshold TD-SCDMA frequency becomes high priority, its RSCP measurements, thereby improving the measurement accuracy. 另外,由于目前GSM下只广播TD-SCDMA的频点,因此,需要对已广播的TD-SCDMA频点进行周期性的搜索,以确保TD-SCDMA的同频小区能够被发现。 Further, since only the current GSM broadcast frequency of TD-SCDMA, therefore, require periodic searches for the TD-SCDMA radio frequency has to ensure that the same frequency of TD-SCDMA cell can be found.

[0043] 本实施方式可应用在GSM/TD-SCDMA双模终端处于GSM模式下时,发起的对TD-SCDMA的测量。 When the [0043] embodiment of the present embodiment can be applied in GSM / TD-SCDMA dual-mode terminal is in GSM mode, initiating measurement of the TD-SCDMA. 但是,可以理解,本实施方式不仅对GSM/TD-SCDMA双模终端有效,而且对其他任何非TD-SCDMA模式下的终端需要测量TD-SCDMA小区时也有效。 However, it is understood that the present embodiment is not valid for the terminal GSM / TD-SCDMA dual-mode, but is also effective when measuring TD-SCDMA terminals in the cell needs to any other non-TD-SCDMA mode. [0044] 另外,值得一提的是,在本实施方式中,第一门限值为系统消息中广播的重选门限值。 [0044] Further, it is worth mentioning that, in the present embodiment, the first threshold is the threshold value reselection of the broadcast system message. 由于异系统的测量目的主要就是保证异系统间的切换能顺利执行,因此以系统消息中广播的重选门限值作为第一门限值,可以保证所选取的需要进行RSCP测量的TD-SCDMA频点是信号满足切换要求的小区的频点。 TD-SCDMA as the main purpose of measurement is to ensure inter-system handover between different systems can be successful, the message to a broadcast system reselection threshold value as a first threshold value, may be selected to ensure the required measuring RSCP frequency signal is frequency cell satisfies the handover requirements.

[0045] 此外,可以理解,第一门限值并非必须是系统消息中广播的重选门限值,也可以是该重选门限值上下一预定范围内的值,如比该重选门限值高3db或低3db等。 [0045] Further, it is understood, is not necessarily a first threshold value reselection threshold value of the system broadcast message, it may be a value within a predetermined range in the next reselection threshold value, such as the ratio of the gate reselection 3db 3db high or low limits and so on. 也就是说,第一门限值可以是根据根据系统消息中广播的重选门限值所获得的一个门限值,也可以是设置的其他门限值。 That is, the first threshold value may be a value based on a threshold gate according reselection of the broadcast system message obtained, may be another set threshold.

[0046] 本发明第二实施方式涉及一种时分同步码分多址系统的测量方法。 [0046] The second embodiment of the present invention relates to a method for measuring the TD-SCDMA system.

[0047] 第二实施方式在第一实施方式的基础上进行了改进,主要改进之处在于:在对选取的各TD-SCDMA频点进行RSCP的测量时,同时对未选取的其余各TD-SCDMA频点(即RSSI小于或等于重选门限值的TD-SCDMA频点)分别进行RSSI的测量。 [0047] The second embodiment is an improvement on the first embodiment, the main improvement is that: when the respective selected frequency TD-SCDMA RSCP is measured, while the rest of each unselected TD- SCDMA frequency (i.e., RSSI is less than or equal to the threshold value reselection frequency TD-SCDMA) to measure the RSSI, respectively. 如果对未选取的各TD-SCDMA频点测量到的RSSI值大于第二门限值,则对大于第二门限值的RSSI值所对应的TD-SCDMA频点,进行训练序列码的检测,根据检测到的训练序列码对该TD-SCDMA频点进行RSCP的测量,并根据RSCP的测量结果进行TD-SCDMA小区的同步维持,如图3所示。 If each of the TD-SCDMA unselected frequency measured RSSI value is larger than a second threshold value, the frequency of the TD-SCDMA RSSI value is greater than the second threshold value corresponding to the detected training sequence code, according to the detected training sequence code of the TD-SCDMA RSCP measurement of frequency, and synchronization maintenance TD-SCDMA cell RSCP measurement result, as shown in FIG. 其中,第二门限值大于或等于选取的各TD-SCDMA频点的RSCP值中的最大值,并且大于或等于第一门限值。 The maximum value of RSCP of each TD-SCDMA wherein the second threshold value is greater than or equal to the selected frequency points, and greater than or equal to the first threshold value. 比如说,如果选取的各TD-SCDMA频点的RSCP值中的最大值大于或等于第一门限值,则第二门限值为选取的各TD-SCDMA频点的RSCP值中的最大值;如果选取的各TD-SCDMA频点的RSCP值中的最大值小于第一门限值,则第二门限值为第一门限值。 For example, if the maximum values ​​of the TD-SCDMA RSCP selected frequency is greater than or equal to the first threshold value, the second threshold value is the maximum value of each TD-SCDMA RSCP selected frequency in ; if the maximum values ​​of the TD-SCDMA RSCP selected frequency is less than a first threshold value, the second threshold is a first threshold value.

[0048] 在本实施方式中,未被选取的各TD-SCDMA频点的频点仍有机会进行RSCP的测量,可以有效避免应搜索的TD-SCDMA频点的遗漏。 [0048] In the present embodiment, the frequency of each TD-SCDMA unselected frequency bins have an opportunity to measure the RSCP, can effectively avoid missing TD-SCDMA frequency point to be searched.

[0049] 另外,由于在TD-SCDMA系统中,RSSI的测量结果大于等于RSCP的测量结果,也就是说,如果TD-SCDMA频点A的RSSI小于TD-SCDMA频点B的某个小区的RSCP,则A频点下所有的TD小区的RSCP必然小于频点B下该小区的RSCP。 [0049] Further, since the TD-SCDMA system, the RSSI measurements greater than or equal RSCP measurement result, that is, if TD-SCDMA RSSI is smaller than the frequency A frequency of a TD-SCDMA cell B RSCP , then a frequency at all cells TD RSCP RSCP must be smaller than the frequency of the B cell. 因此,将第二门限值设置为选取的各TD-SCDMA频点的RSCP值中的最大值,也就是说,测量RSSI的频点转换为RSCP测量,需要满足的条件是测量的RSSI值大于测量到的RSCP值中的最大值,并且大于第一门限值,从而有效控制了终端用于测量TD-SCDMA系统的功耗。 Thus, the maximum value of the second RSCP threshold value set for the TD-SCDMA frequency selected in, say, the RSSI measured frequency is converted into RSCP measurement condition to be met is greater than the measured RSSI value maximum measured RSCP value and greater than a first threshold value, thereby effectively controlling power consumption of a terminal for measuring the TD-SCDMA system.
