Description

移动台相对基站的位置定向法、移动无线系统和定向设备 Position alignment method of the mobile station relative to the base station, the mobile radio system and orientation device

技术领域 FIELD

本发明涉及一种在按照移动无线标准工作的移动无线系统中对移动台相对于基站的位置进行定向的方法,以及涉及一种相应的移动无线系统和一种定向设备。 The present invention relates to a method in a mobile radio system operating in accordance with the standard mobile radio station relative to the position of the mobile station is directed, and to a corresponding mobile radio system and an orienting apparatus.

背景技术 Background technique

在3GPP(第三代合作计划)的范围内,目前对UMTS-TDD-标准(通用移动电信系统,时分双工)进行标准化。 Within the scope of 3GPP (Third Generation Partnership Project), the current standard for UMTS-TDD- (Universal Mobile Telecommunications System, Time Division Duplex) for standardization. 根据该标准规定(参见3GPPTS 25.224,V5.1.0,章5.6.3):对于移动台首次接入到移动无线网,需要发送一个接入序列来给出连接请求信令。 (See 3GPPTS 25.224, V5.1.0, Section 5.6.3) in accordance with the standard: the first access for the mobile station to the mobile radio network, the access needs to send a connection request signaling sequence given. 在该标准(3GPP TS25.223,V5.1.0,附录B,章B2)中定义了256种这样的接入序列。 256 kinds are defined in the access sequence of such standard (3GPP TS25.223, V5.1.0, to Appendix B, Section B2). 在UMTS-TDD-标准中规定的每个这种接入序列为128个码片长。 Each such access sequence in a predetermined standard UMTS-TDD- 128 chips long. 给每个基站或每个无线小区分配该256个接入序列中的8个。 To each base station or each wireless cell 256 allocate access to the eight sequences. 移动台通过固定地结合基站的其它小区参数(基本中间序列码,扰码)来获知可供使用的接入序列(参见3GPP TS 25.223,V5.1.0,章9.3中的表格)。 The mobile station access sequence may be learned by fixedly available in conjunction with other base stations of cell parameters (intermediate base sequence code, scrambling code) (see 25.223, V5.1.0, Chapter 9.3 in the form 3GPP TS). 于是,一个移动台可以随机地选择该8个接入序列中的一个,并将其传输给基站以发出连接请求信令。 Thus, a mobile station can randomly select one of the eight access sequences and transfer it to the base station to send a connection request signaling. 这是在所谓的上行链路导频时隙(UpPTS)中实现的,该导频时隙在时间上直接位于上行链路传输帧的第一个时隙之前。 This is achieved in a so-called uplink pilot time slot (UpPTS), the pilot slot in time slot is located directly before the first uplink transmission frame. 如果基站接收到所述接入序列中的一个,则它首先不知道该发射是来自于哪一个移动台。 If the base station receives an access sequence, it does not know that the first mobile station which is transmitting from. 因此,按照上述标准在下一个步骤中,由基站利用预先发送的接入序列给有关的移动台分配一个确定的RACH资源,移动台随后通过该RACH资源将一个用于标识自己的识别码发送给基站。 Thus, the above criteria a next step, the base station using a predetermined access sequence transmitted by the RACH resource is assigned to a determination of the mobile station, the mobile station then through a RACH resource identification code identifying itself to the base station . 在此,RACH资源的分配是通过所谓的FPACH(快速物理接入信道)实现的。 Here, the RACH resource allocation is achieved by so-called the FPACH (Fast Physical Access Channel). 利用该方式,基站最后可以确定是哪个移动台发出了连接请求信令。 With this embodiment, the base station may determine that the last mobile station which issued the connection request signaling.

在同样的移动无线标准中,需要规定相对于各个基站对移动台的位置进行定向。 In the same mobile radio standard, it is necessary for each base station relative to a predetermined location of the mobile station is oriented. 若在基站内采用了定向天线,则这种定向是可能的。 If the use of directional antennas in the base station, then this orientation is possible. 对于这种定向,目前规定由基站为此而分析UL DPCH(上行链路专用物理信道)上或PUSCH(物理上行链路共享信道)上的信号。 For this orientation, the analysis of the current signal on a predetermined UL DPCH (Uplink Dedicated Physical Channel) or a PUSCH (Physical Uplink Shared Channel) from the base station for this purpose. 这是一些业务信道,移动台在建立连接之后、也即在按照上述方式发出连接请求信令之后在这些业务信道上把有用数据传输给基站。 These are some of the traffic channel, the mobile station after a connection is established, i.e. after the connection request is issued in the signaling traffic channel to transmit useful data to the base station as described above. 对于这种连接建立,必须给各个移动台预留相应的传输资源(扩展码,频段,时隙)。 For such a connection is established, the reservation must respective transmission resources (spread code, frequency, time slot) to each mobile station. 在标准3GPP TS 25.225,V5.1.0,章5.2.14和TS 25.305,V5.4.0,章8中讲述过用UL DPCH或PUSCH来执行定向。 In standard 3GPP TS 25.225, V5.1.0, Chapter 5.2.14 and TS 25.305, V5.4.0, Chapter 8 describes through a UL DPCH or PUSCH performed orientation.

发明内容 SUMMARY

本发明所基于的任务在于用另一种方式来进行上述的定向。 The present invention is based on the object in that orientation to the above-described another way.

该任务利用权利要求1所述的方法、权利要求9所述的移动无线系统以及权利要求10所述的定向设备来解决。 This object is achieved with a method as claimed in claim 1, and a mobile radio system as claimed in claim 9, said orientation device according to claim 10 to resolve. 本发明的优选改进和扩展方案由从属权利要求给出。 Preferred modifications and developments of the invention are given by the dependent claims.

对于本发明的用于在按照移动无线标准工作的移动无线系统中对移动台相对于基站的位置进行定向的方法,其规定:由所述的移动台把一个接入序列传输给基站,以及借助由基站所接收的接入序列来执行定向。 For the method of the present invention in a mobile radio system operating in accordance with the standard mobile radio station relative to the position of the mobile station is directed, which is specified by: the mobile station transmitting the access sequence to a base station, and means access sequence received by the base station performs directional. 此处的接入序列涉及由移动无线标准规定的多个接入序列中的一个,以便被移动台用来向基站发送连接请求信令,在此,移动台可以被理解为各种任意的移动无线电台。 Access sequence herein relates to one of a plurality of predetermined access sequence by the mobile radio standard, so as to be used for the mobile station transmits a connection request signaling to the base station, in this case, the mobile station may be understood as any movement of the various radio station. 基站在这里可以被理解成静态或移动的各种任意的其它无线电台。 The base station may here be understood to various static or moving any other radio station. 移动无线系统在这里被理解成各种任意的无线系统,其中采用了所述的移动台和基站。 Mobile radio system is herein understood any of a variety of wireless systems, which use mobile station and the base station. 此处的移动无线标准被理解成所述无线系统之一所采用的、规定了用于发送连接请求信令的接入序列的各种标准。 Mobile radio standards to be understood herein as one of the radio system used, various standards for transmitting a predetermined connection request signaling of the access sequence.

在借助分配给各移动台的传输资源进行定向之前,首先按照上述的现有技术建立一个连接,在此期间本发明可以有利地实现已经在把传输资源分配给移动台之前就执行定向。 Means before transmission resources allocated to each mobile station oriented, first establish a connection according to the above prior art, during which the present invention may be advantageously implemented have been executed before the orientation allocating transmission resources to the mobile station. 这可以在移动台首次在移动无线系统中投入运行时在该移动台第一次接入到系统期间来实现,因为根据本发明,给定向采用了被规定用于发送连接请求信令的接入序列。 This may be when the mobile station is first put into operation in a mobile radio system in which the mobile station during a first access system to be realized, since according to the present invention, to use a directional access request signaling is transmitted is connected to a predetermined sequence.

相对于文章开头所述的现有技术,本发明具有以下优点:为了定向,不需要分配用于业务通信连接的传输资源,例如时隙、频段、扩展码或扰码等。 The prior art with respect to the beginning of the article, the present invention has the following advantages: For orientation, no traffic transmission resources allocated for the communication connection, for example slots, frequency bands, spreading or scrambling codes. 另一个优点在于,可以在一个为此特别预留的时隙(UpPTS)内发送譬如遵照UMTS-TDD-标准的接入序列,使得这些接入序列只与其它的接入序列形成干扰,而不会与业务信道形成干扰。 Another advantage is that, for this purpose may be sent in a particular reserved slot (UpPTS) in accordance with such standards UMTS-TDD- access sequence, such that the access sequence only interfere with other access sequence, without It will interfere with the traffic channel. 但是,通过合适地选择接入序列,接入序列之间的干扰可以远远小于由业务信道所带来的干扰。 However, by suitably selecting an access sequence, the interference between the access sequence can be much smaller than the interference caused by traffic channels.

本发明还有一个优点在于,定向已经可以在把信道分配给移动台之前被执行。 Yet another advantage of the present invention is that the orientation has to be performed prior to assigning a channel to the mobile station. 因此,譬如已经可以在信道分配时考虑定向的结果。 Thus, for example, the results may be considered already oriented in the channel assignment. 如果得知在所测定的方向上存在另一个尚能提供空闲资源的基站,而连接建立请求所指向的那个基站的传输资源已将近被用完,那么,尤其可以拒绝同时地通过该接入序列所发出的连接请求信令。 If another base station that offers free resources can still exist in the measured direction, and the connection establishment the base station transmission resource that the request is directed has nearly been used up, then, in particular, may be denied access sequence simultaneously by the issued connection request signaling.

根据本发明的第一实施方案,由移动台发送的接入序列既被用来执行定向,也被所述移动台用来发送连接请求信令。 According to a first embodiment of the present invention, access sequence transmitted by the mobile station is used to perform either orientation, is also used by the mobile station transmits a connection request signaling. 因此,发送接入序列和在基站内接收接入序列被有利地同时用于两个目的。 Thus, the access sequence transmitting and receiving in the base station access sequence is advantageously used for both purposes.

本发明该实施方案的另一改进规定,存储由基站所执行的定向的结果和存储从该结果到为进行该定向所采用的接入序列之间的对应关系。 This embodiment of the present invention is a further embodiment of the improvement predetermined, and stored in the storage orientation results performed by the base station is carried out to result from the correspondence relationship between the access sequences employed in this orientation. 由移动台在以后的时间点把一个明确地标识自己的识别码通知给基站。 By the mobile station at a later point in time to unambiguously identify its identification code to the base station. 产生从该移动台的识别码到为进行该定向所采用的接入序列之间的对应关系。 For generating a correspondence between the orientation of the access sequence used from the identification code to the mobile station. 最后,产生从所存储的结果经为进行该定向所采用的接入序列再到移动台的识别码之间的对应关系。 Finally, the results generated from the stored sequence for which the access by the orientation adopted then the correspondence between the identification code of the mobile station. 利用该方式可以有利地解决以下问题,即:在移动台通过发送接入序列被首次接入到移动无线系统时,基站首先并不知道它是哪个移动台,也即该有关的移动台具有何种识别码。 With this embodiment may advantageously solve the following problems, namely: When the mobile station access sequence is transmitted by the first access to the mobile radio system, the base station first is that it does not know which mobile station, i.e. the mobile station associated with the HE identification code. 根据本发明,虽然已经在该时间点上借助所接收的接入序列进行定向,但由于不知道该识别码,所以尚不能分配所求出的定向结果。 According to the present invention, although the access sequence has been received by the time point at orientation, but I do not know the identification code, it is not yet assigned orientation results obtained. 只有当移动台将其识别码告诉给基站之后,才在下一个步骤中执行该分配。 Only after the mobile station when it is told to the base station identification code, before the implementation of the allocation in the next step. 在此,可以通过重新传输事先已采用的接入序列来通知所述的识别码,使得能够简单地实现从该识别码到定向结果之间的对应关系。 Here, the identification code may be notified by the access sequence of the retransmission has been previously used, can be easily realized so that the correspondence relationship between the identification code from the orientation results.

优选地,移动台可以通过该移动台在首次接入移动无线系统时的上述第二个步骤来通知所述的识别码。 Preferably, the mobile station may be in the second step when the first access mobile radio system to notify the identification code by the mobile station. 如上所述的,该第二步骤规定:基站根据所接收的接入序列给移动台分配一个RACH资源,移动台随后在该资源上把连接建立所需要的其它信息传输给基站。 As described above, the provision of the second step: the base station allocating resources to the mobile station a RACH according to the received access sequence, then the mobile station in the connection establishment on the resource needed to transmit other information to the base station. 此时,该信息也包括移动台的识别码。 At this point, the information also includes the identification code of the mobile station. 另外,在所分配的RACH资源上,移动台还把同样的接入序列与所述的信息一起传输给基站,使得从所采用的接入序列到移动台的识别码之间实现明确的对应关系。 Further, on the RACH allocated resources, the mobile station also access the same information sequence is transmitted to the base stations together such that between the mobile station identification code to achieve a clear correspondence between the access sequence employed . 利用该方式能实现从定向结果到移动台的识别码之间的明确对应关系。 This embodiment can be realized by using a clear correspondence between the results from the directed to the mobile station identification code.

根据本发明的第二实施方案,给基站分配一个无线小区,其中无线小区被理解为基站的无线服务区。 According to a second embodiment of the present invention, to assign a cell radio base station, wherein the radio cell is understood as the wireless service zone of the base station. 在该实施方案中,所述为进行该定向所采用的接入序列至少在该基站的无线小区内被专门地预留以用于执行定向,以致于阻止用该接入序列在该无线小区内发送连接请求信令。 In this embodiment, the access sequence is employed for this orientation is exclusively reserved for the radio cells at least within the base station for performing the orientation so that the stop with the access sequence within the radio cell transmits a connection request signaling. 这有利地区分了以下的接入序列,即把在该无线小区内实际上被用于发送连接请求信令(如移动无线标准中所规定的一样)的接入序列与被用于定向的那些接入序列区分开来。 This advantageously distinguish the following access sequence, i.e. in the radio cell to actually be used to transmit a connection request signaling (e.g., a mobile radio as defined in the standard) in the access sequence for targeting those distinguish access sequence. 因此,尤其还可以执行定向而不发送连接请求信令-例如在已经给有关的移动台建立完通信连接的期间。 Thus, in particular, the orientation may also be performed without transmitting the connection request signaling - for example during the relevant mobile station has been completed to establish a communication connection. 在此,为专门执行定向而预留接入序列只被设定在某个时延内,使得在不同的时间点可以为此预留所述接入序列中的不同接入序列。 Here, the orientation is performed exclusively reserved access sequence is set only in a certain delay, so at different points in time different access sequences may be reserved in the access to do so. 于是,其余的接入序列分别被移动台用来发送连接请求信令。 Thus, the rest of the access sequences are used by the mobile station transmits a connection request signaling.

根据本发明的该实施方案的一种改进,由所述的基站给所述的移动台分配所述为定向目的而采用的接入序列。 An improved embodiment of the embodiment of the present invention, by the base station to the mobile station access sequence assigned to the purpose for which the orientation. 这在移动台发送接入序列之前实现,其前提是基站已得知移动台的识别码。 This mobile station transmits before the access sequence implemented, provided that the base station has informed the mobile station identification code. 然后,基站可以有目的地利用该移动台的识别码而通知该移动台:它应该发送哪个接入序列以用于定向的目的。 Then, the base station may have a destination using the identification code of the mobile station and notifies the mobile station: Which access sequence for targeting purposes it should send.

根据一种改进方案,由所述的基站给所述的移动台分配一个时间点以用于发送该接入序列。 According to one refinement, the base station to the mobile station according to a time distribution point for transmitting the access sequence. 这可以有利地实现:同一个接入序列可以同时地被分配给多个移动台以用于执行定向。 This may advantageously be achieved: the same access sequence may be simultaneously allocated to a plurality of mobile stations for performing orientation. 于是,可以简单地通过考虑接入序列在基站内的各个接收时间点来分配借助该接入序列所执行的定向的结果。 Thus, simply by means of directional distribution of the results of the access sequence performed by considering the respective reception time points of the access sequence within the base station. 也即,通过分配不同的时间点以让多个不同的接入电台发送同样的接入序列,将会自动地在基站内得到不同的接收时间点,从而可以实现从定向结果经接收时间点再到移动台识别码之间的对应关系。 That is, by allocating different time points to allow a plurality of different access station transmits the same access sequence, will automatically obtain different reception points of time within the base station, which can achieve the results directed again through the reception time point the correspondence between the mobile station identification number.

根据另一改进方案,由所述的基站给所述的移动台分配一个发射功率以发送为执行所述的定向而采用的接入序列。 According to a further refinement, by the base station to the mobile station is assigned a transmit power for transmitting the access sequence is performed according to the orientation adopted. 利用该方式可以确保由移动台发出的接入序列能以足够高的接收功率到达基站。 With this embodiment can ensure access sequence sent by the base station to the mobile station to reach a sufficiently high received power.

本发明的移动无线系统和本发明的用于对移动无线系统中的移动台位置进行定向的设备被如此构造,以致于其能执行本发明的方法和具有为此所需的装置。 Mobile radio system according to the present invention and the present invention for a mobile radio system mobile station position orienting device is so constructed that it can perform the method of the present invention and having a means necessary for this.

附图说明 BRIEF DESCRIPTION

下面借助附图所示的实施例来详细讲述本发明,其中:图1示出了移动无线系统的一部分, To describe in detail the present invention, wherein the embodiment illustrated in the drawings by the following: FIG 1 shows a part of a mobile radio system,

图2示出了图1所示移动无线系统的基站,以及图3示出了图2所示基站的存储器的内容。 Figure 2 shows a base station of the mobile radio system shown in Figure 1, and Figure 3 shows the contents of a memory shown in FIG. 2 the base station.

具体实施方式 Detailed ways

图1所示的是UMTS-TDD-移动无线系统SYS的一部分。 It is part of the UMTS-TDD- mobile radio system SYS shown in Fig. 显然本发明也可以应用于其它的移动无线系统。 Obviously the present invention may be applied to other mobile radio systems. 图1只给出了移动无线系统SYS的一个无线小区C。 FIG 1 shows a radio cell C. The mobile radio system SYS 该无线小区C属于基站BS。 The radio cell C belongs to base station BS. 在无线小区C中有一个移动台MS和另一个移动台MS1。 A mobile station MS and another mobile radio station MS1 ​​in the cell C. 在图1的括弧中示出的附图标记是表示可选择的信号。 In the parenthesis is shown in FIG. 1 is a selectable reference numerals signal. 下面来详细讲述本发明的第一实施例,其中没有传输这些可选择的信号。 The following describes in detail a first embodiment of the present invention, wherein these alternative no transmission signals.

如文章开头所述,UMTS-TDD-标准给每个无线小区C也规定了8个不同的接入序列,以便由移动台用来向基站发射连接请求信令。 As the beginning of the article, UMTS-TDD- standard to each radio cell C also provides for eight different access sequence to be used by the mobile station transmits a connection request signaling to the base station. 图1中的移动台MS把该接入序列S中的一个传送给基站BS以发出连接请求信令。 The mobile station MS in FIG. 1 transmits a sequence S of the access to the base station BS to send a connection request signaling. 基站BS配备了一个由天线场实现的定向天线A。 The base station BS is equipped with a directional antenna is achieved by the antenna field A. 借助定向天线A,基站BS能够通过测定接入序列S的入射方向来对移动台MS相对于基站BS的位置进行定向。 By means of directional antennas A, the base station BS can be oriented with respect to the position of the base station BS to the mobile station MS by determining the direction of incidence of the access sequence S. 借助定向天线对所接收的信号进行定向是本领域技术人员所公知的,在此不再赘述。 The received signal is performed by means of directional antennas are directional skilled in the art well known, are not repeated here. 每个移动台MS、MS1在连接请求时把所述接入序列中的一个发送给基站BS。 Each mobile station MS, MS1 transmits to a base station BS to the access sequence in the connection request. 为此,由基站来广播需要在其小区C内使用的全部8个接入序列,并由移动台从中随机地选取一个。 To this end, broadcast by the base station which requires the use of cell C in all eight access sequence, by the mobile station from a randomly selected. 移动台MS把接入序列S传输给基站BS,而另一移动台MS1则把另一个接入序列S1传输给基站BS。 The mobile station MS to access sequence transmitted to the base station S BS, the mobile station MS1 ​​and another put another access sequence S1 to the transmission base station BS. 基站BS针对每个接收的接入序列S、S1执行上述的定向。 The base station BS for each of the received access sequence S, S1 executes the orientation. 另外,该基站还在接下来的步骤中把所希望的连接用的传输资源分配给每个移动台MS、MS1。 Further, the base station is also the next step the desired allocation of transmission resources connected to each mobile station MS, MS1.

图2示出了图1的基站BS。 Figure 2 shows a base station BS of FIG. 所示的只是对理解本发明较为重要的部分。 It is shown only for understanding the more important parts of the present invention. 基站BS具有一个发射和接收单元TRx,它与定向天线A相连接。 The base station BS has a transmitting and receiving unit TRx, which is connected to the directional antenna A. 所述的发射和接收单元TRx与一个信号处理单元SIG相连接,该信号处理单元用于处理经天线A所接收的信号和需经该天线A传输的信号。 The transmitting and receiving unit and a signal processing unit TRx SIG is connected to a signal processing unit for processing via the antenna A and the signal received via the antenna A desired signal transmission. 另外,基站BS还具有一个用于执行上述定向的设备R。 The base station BS further includes a device for performing the above-described orientation R. 该定向设备分析经天线A所接收的接入序列S、S1,并求出所述接入序列入射到天线A的方向。 Analysis of the orientation device via the antenna A received access sequence S, S1, and obtains the access sequence to the incident direction of the antenna A. 定向的相应结果E、E1针对每个被接收的接入序列而被分开地存储在基站BS的存储器M中。 Orientation corresponding results E, E1 is stored in the memory M of the base station BS for each of the received access sequence separately.

在图3中以表格形式而摘要地示出了图2的存储器M的内容。 In FIG 3 a summary in table form and the content of the memory M shown in FIG. 2. 在此,存储器M具有成列的录入项,以用于位于无线小区C中的每个移动台MS、MS1。 Here, the memory M with the entries of a column, for each mobile station MS located in a cell C of the radio, MS1. 图3中的表格给出了存储器M在两个不同时间点t1,t2处的内容。 The table in Figure 3 shows two different points at times t1, t2, the contents of the memory M. 在第一时间点t1,通过基站BS已经从图1所示的两个移动台MS、MS1接收两个接入序列S、S1,并分别执行定向。 At a first time point t1, the mobile station MS has two shown in FIG. 1 via the base station BS, MS1 receives two access sequence S, S1, and respectively executes directive. 于是,在存储器中既存储接入序列S,也(与该接入序列相对应地)存储相应的结果E、E1。 Thus, both stored in a memory access sequence S, also (corresponding to the access sequence) stored in the corresponding result E, E1. 随后,如UMTS-TDD-标准中所规定的一样,由基站BS通过一个消息FP、FP1(见图1)给已经通过发送接入序列给出信令请求的每个移动台MS、MS1分配一个RACH资源,以用于移动台首次接入到移动通信系统中的第二个步骤。 Subsequently, as in UMTS-TDD- standard as specified by the base station BS through a message FP, FP1 (see FIG. 1) to each mobile station MS has been given of a signaling request by sending an access sequence, a dispensing MSl RACH resources for the first access to the mobile station in a mobile communication system, a second step. 在该第二个步骤中,每个移动台MS、MS1给基站BS发送一个识别码K、K1,该识别码明确地标识了各个移动台MS、MS1(见图1)。 In the second step, each of the mobile stations MS, MS1 to the base station BS sends an identification code K, K1, the identification code clearly identifies each mobile station MS, MS1 (Figure 1). 由于按照此处所考察的标准是由基站给移动台分配一个确定的RACH资源来执行所述的第二个步骤,所以基站可以明确地把所述的识别码K、K1分配给预先由有关的移动台MS、MS1发送的接入序列S、S1。 Since the RACH resource is assigned is determined in accordance with a standard herein investigated by the base station to the mobile station to perform the second step, the base station can explicitly said identification code K, K1 previously assigned to the mobile by the relevant station MS, the access sequence sent by S MS1, S1. 根据图3所示,随后在第二个时间点t2,与定向结果E、E1相对应地在基站BS的存储器M中存储各移动台MS、MS1的相应识别码K、K1。 According to FIG. 3, and then at a second time point T2, and the orientation results E, E1 corresponding to each of the mobile station MS stored in the memory M, the base station BS, the corresponding identification code MSl K, K1. 在此,这种对应关系通过在移动台首次接入到移动无线系统时的第一和第二个步骤中所采用的接入序列S、S1来实现。 Here, this relationship through a first access sequence S and a second step when the first mobile station to the mobile wireless access system employed, Sl achieved.

显然,图2所示的定向设备R和存储器M可以不在基站BS内,而是可以包含在位于基站BS之外的单元中,例如与移动无线系统的多个基站相连接的中央单元,如基站控制器。 Clearly, the orientation of the device in FIG memory M and R 2 may not be shown within the base station BS, but may include means located outside the base station BS, for example, a central unit and a plurality of base stations connected to mobile radio system, the base station controller.

在该第一实施例中,由基站BS对移动台MS、MS1在首次接入到移动无线系统SYS时的第一步骤中所传输的每个接入序列进行定向。 In this first embodiment, each of the access sequence by the base station BS to the mobile station MS, MS1 in the first step at the first access to the mobile radio system SYS in orienting transmitted.

接下来讲述本发明的第二实施例。 Next, about the second embodiment of the present invention. 对此请参考图1的括弧中所示的附图标记。 In this regard, please reference numeral 1 in parentheses refer to FIG. 在该实施例的无线小区C中,事实上并没有采用由UMTS-TDD-移动无线标准为此所规定的、被移动台用来向基站发送连接请求信令的所有8个接入序列。 In the radio cell C of this embodiment in fact does not use defined by the UMTS-TDD- mobile radio standards for this purpose, the mobile station is used to transmit all eight access sequence to the base station a connection request signaling. 替而代之的是,图1中的两个被用于定向的接入序列S、S1在该实施例中被专门地预留以执行所述的定向,从而不可能用于移动台的连接请求信令。 Is employed instead, two in FIG. 1 is oriented for access sequence S, S1 is specifically oriented to execute the reserved in this embodiment, thus making it impossible to connect the mobile station request signaling. 此时虽然可以在移动无线系统的另一个无线小区C中提供同样的接入序列以供支配,但一定不要预留该接入序列中的、与此处所考察的无线小区C相同的接入序列来执行定向。 At this time, although the access sequence may be provided in the same radio cell C to another mobile radio system for disposable, but must not be reserved in the access sequence, the same access sequence C and examined herein radio cell to perform orientation.

在该实施例中,基站BS给需要被定向的每个移动台MS、MS1分配一个预留的接入序列S、S1。 In this embodiment, each of the base station BS to the mobile station MS need to be oriented, MSl assigned a reserved access sequence S, S1. 而且,除了所述的接入序列S、S1之外,基站BS还给每个移动台MS、MS1分配一个发射功率P、P1和一个时间点t、t1,其中移动台随后应该以上述功率和在所述的时间点上发送各个接入序列S、S1。 Further, in addition to the access sequence S, S1, the base station BS back to each mobile station MS, MS1 is assigned a transmit power P, P1, and a time point t, t1, where the mobile station should be followed as described above power and transmitting each access sequence S, S1 is the point in time. 然后,基站BS借助分配给移动台MS、MS1的、且随后由给移动台发送给基站BS的接入序列S、S1来执行上述的定向。 Then, by the base station BS allocated to the mobile station MS, MS1, and then sent to the mobile station by the base station BS to the access sequence S, S1 to perform the above-described orientation.

为了在第二实施例中把接入序列S、S1分配给移动台MS、MS1,需要让基站预先知道各个移动台的识别码K、K1。 In a second embodiment, in order to allocate access sequence S, S1 to the mobile station MS, MS1, the base station needs to know in advance so that each mobile station identification number K, K1. 通过以上借助第一实施例所讲述的、按照UMTS-TDD-标准的两级式首次接入方法,基站BS便可以获得该信息。 The above embodiment describes the first embodiment, in accordance with UMTS-TDD- standard two-stage method by means of the first access, the base station BS can obtain the information. 如图1所示,在第二实施例中,当已经以业务信道的形式在移动台MS、MS1和基站BS之间建立用于有用数据传输的连接V、V1时,便执行所述的定向。 FIG orientation, in the second embodiment, when the traffic channel has the form of a V for establishing a connection in the useful data transmission between the mobile station MS, MS1 and the base station BS, V1, is executed in the FIG. 1 .

显然也可以组合所述的第一和第二实施例。 Obviously may be combined first and second embodiments described. 于是,时间上在先的定向可以与连接请求信令同时地被实现(根据第一实施例),并随后(在已有的连接中)按照第二实施例被更新。 Thus, the time preceding the connection request signaling orientation may be achieved simultaneously (a first embodiment), and then (in the conventional connection) is updated according to a second embodiment.

为代替在时间点T、T1发送接入序列S,基站BS也可以通知移动台MS、MS1:该移动台应该多次、例如周期性地发送接入序列S、S1,以便每次都能更新所述的定向。 In place of the time point T, T1 transmission access sequence S, the base station BS may inform the mobile station MS, MS1: the mobile station should repeatedly, for example periodically sends access sequence S, Sl, so that every time update the orientation.

作为在第二实施例中通告用于发送所述接入序列S、S1的发射功率P、P1的替换方案,或者在其基础之上,也可以规定:在移动台MS、MS1的接入序列S、S1的传输尝试失败的情况下,由移动台分别逐步地提高用于重新传输尝试的发射功率。 In a second embodiment, the advertisement for transmitting the access sequence S, S1 alternative transmission power P, P1, or on the basis thereof, can also be provided: a mobile station in the MS, MS1, access sequence S, S1 of the transmission case failed attempt, by the mobile station, respectively, gradually increase the transmission power for re-transmission attempts. 通过分配给移动台MS的时间点T发送接入序列S,基站BS可以明确地把所接收的接入序列S分配给移动台MS,而移动台也不必与接入序列同时地传输其识别码K。 Allocated to the point in time T of the mobile station MS sends an access sequence S, the base station BS may explicitly assigned to the received access sequence S to the mobile station MS, and the mobile station do not have access sequence transmitted simultaneously with its identification code K. 也即,基站BS知道它自己已经给哪个移动台MS、MS1分配了哪个接入序列S以便在哪个时间点T、T1上进行发送。 That is, the base station BS to know which mobile station MS has to itself, which MSl assigned access sequence to which S at time point T, the transmission T1. 因此,通过基站BS内的接收时间点,基站可以容易地确定出每次接收的接入序列S、S1来自于哪个移动台MS、MS1。 Thus, by receiving the time point of the BS in the base station, the base station can be readily determined each time the received access sequence S, Sl from which mobile station MS, MS1 on.
