Description

一种基站重构方法 A base station reconstruction method

本发明涉及在无线通信网络的不同无线收发信机设备之间指派通信信道的一种方法和装置。 A method and apparatus for assigning a communication channel between the present invention relates to a wireless communication network, different wireless transceiver equipment. 本发明尤其涉及在蜂窝无线通信网络中不同无线收发信机设备之间的数据传输信道上提供无线信道重构故障的无缝恢复的一种方法和装置。 The present invention particularly relates to data transmission channels between the different radio transceiver equipment in a cellular radio communication network to provide a method and apparatus for seamlessly recover reconstituted wireless channel failure.

近来,用于移动通信的无线通信网已非常普遍。 Recently, wireless communication network for mobile communication has been very popular. 这种无线通信网在各用户的移动无线收发信机设备之间建立相互通信,前述移动无线收发信机设备作为第一无线收发信机设备,此后称为移动台MS。 Such a wireless communication network to establish mutual communication between the user's mobile wireless transceiver devices, the mobile radio transceiver device as a first wireless transceiver equipment, hereinafter referred to as mobile station MS.

这种蜂窝网络一般由多个静止的无线收发信机设备组成,前述静止的无线收发信机设备作为第二无线收发信机设备,此后称为基站BS。 Such a cellular network generally consists of a plurality of stationary radio transceiver device composed of the stationary radio transceiver device as a second wireless transceiver equipment, hereinafter referred to as base station BS. 可以假定每个基站由无线网络控制器设备RNC控制。 Each base station may assume control of the radio network controller device RNC. 不同移动台MS之间的通信通过至少一个中间基站BS建立。 Communication between different mobile station MS is established by at least one intermediate base station BS. 各基站BS通过其无线覆盖区定义无线小区。 Each cell radio base station BS is defined by its wireless coverage area. 在小区中出现的移动台MS与小区的基站BS建立无线连接。 The base station BS in the cell appears in the cell of the mobile station MS establishes a wireless connection.

这种蜂窝无线网中采用的传输原理一般基于多址接入方法。 This transmission principle employed in the cellular radio network typically multiple access method. 按照这种方法,多个用户例如按照已知的时分多址接入(TDMA)方案,或者按照称为宽带码分多址(W-CDMA)的方案,共享同一信道。 According to this method, a plurality of user, for example according to known time division multiple access (TDMA) scheme, or in accordance with the program called Wideband Code Division Multiple (W-CDMA), and share the same channel. (传输原理例如在欧洲电信标准委员会(ETSI)所发布的GSM规范中规定。这样,在TDMA传输中,(物理)信道被划分成多个时隙,将这些时隙指派给各用户用于通信,时隙分成组,形成帧单元。但是,按照W-CDMA,存在划分成时隙的无线帧,但是多个时隙被指派给同一用户。按照W-CDMA,多址接入基于传输中使用的码,而不是时间。)这种帧中传送的数据包括需要在用户之间传送的实际信息(例如语音数据),以及用于建立和/或维护用户间和/或用户MS和各基站BS间的通信信道的控制数据。 (E.g. predetermined transmission principle in the European Telecommunications Standards Institute (ETSI) GSM specifications published. Thus, in TDMA transmission, the (physical) channel is divided into a plurality of time slots, these time slots will be assigned to each user to communicate , time slots are divided into groups to form a frame unit. However, according to W-CDMA, the presence of a radio frame is divided into time slots, multiple slots are assigned to the same user according to W-CDMA, multiple access transmission based on the use of code, rather than the time.) this data frame transmission includes actual information (e.g., voice data) to be transmitted between users, and for establishing and / or maintaining between users and / or user MS and the base stations BS a control data communication channel between. 数据在所谓的上行传输UL中从各移动台MS传送到小区的基站BS,在所谓的下行传输DL中从基站BS传送到各移动台MS。 Data transmission in a so called uplink transmission UL from each mobile station MS the base station BS to the cell transmitted from the base station BS to each mobile station MS in a so-called downlink transmission DL. 上行和下行传输的各个信道物理上彼此不同,每个基站BS被设计成为上行和下行传输分别提供至少一个信道。 On each of the physical channels uplink and downlink transmission different from each other, each base station BS is designed to uplink and downlink transmission are provided at least one channel. 但是,基站可以调整成为每个传输方向,上行UL或下行DL,分别提供多个不同信道。 However, the base station may be adjusted for each transmission direction, the DL downlink or uplink UL, respectively, a plurality of different channels.

无线通信网中的实际传输通过用户MS和小区基站BS之间的无线路径实现。 The actual transmission in a wireless communication network implemented over the radio path between the user and the MS cell base station BS. 无线路径(空中接口Um)层1(L1物理层)是传输的最低层,由其物理参数和/或其它特性P,P'定义。 Wireless path (air interface Um) layer 1 (L1 physical layer) is the lowest layer of the transmission, by the physical parameters and / or other characteristics of P, P 'is defined. 无线路径特性在物理参数方面,包括例如频率,传输的信号功率,以及小区干扰值。 Wireless channel characteristics in terms of physical parameters, including for example the frequency, power signal transmission, and cell interference values. 无线接口的第1层参数还包括例如前向纠错编码,交织,第一层数据流复用成物理信道的配置。 The first layer further comprises parameters of a wireless interface, for example, forward error correction coding, interleaving, a first layer data streams into physical channel configuration. 物理信道的频率取决于基站侧可用的频率(信道)和/或小区中的业务量负荷,而信号功率参数取决于基站的环境(有或无例如山谷的乡村地区)或者人口密集的城市区域和/或基站BS和与所述基站通信的移动台MS之间的距离。 The frequency of the physical channel depend on the frequency base station side is available (channel) and / or traffic load in the cell, and the ambient signal power parameter depends on the base station (with or without, for example, in rural areas the valley) or densely populated urban areas and / distance between the base station BS and the mobile station MS or the base station in communication.

建立新的、释放旧的或者修改已指派的用户数据流传送业务集(承载业务)都需要修改物理层的参数,例如新的前向纠错编码或者(作为CDMA特定参数)信道化码,还需要考虑改变的环境情况,例如因为移动台MS正远离基站,在基站BS到移动台MS之间的视距范围内有一座山。 Create a new, release the user data from the old or to modify the assigned streaming service set (bearer services) requires the modification of parameters of the physical layer, such as the new forward error correction coding, or (as a CDMA-specific parameter) channelization codes, further need to consider the environmental conditions change, for example because the mobile station MS from the base station n, the base station BS to the hill there is a line of sight between the mobile station MS.

L1参数P,P'的集合以数据传输(消息)的形式从无线网络控制器RNC发送到基站BS和移动台MS。 L1 parameter P, the set of P 'in the data transmission (message) is sent as the radio network controller RNC from base station BS and mobile station MS. 如果参数合法,那么这种消息可以还包括开始时间,即帧编号。 If the parameter is legitimate, then this message may also include the start time, that is, frame number. 该消息通过专用于信令信息传输的(逻辑)信令信道,表示改变实际参数集的请求,例如从集P改变到修改集P'的请求。 The message on the signaling information transmitted through a dedicated (logical) signaling channel, the actual change request represents a parameter set, such as a change to the modified set from the set P P 'requests.

但是,可能会出现改变和/或调整无线接口的信令过程失败的情况。 However, the situation changed and / or adjust the radio interface signaling process failure may occur.

此外,即使将参数传送给移动台MS,该移动台也可能出于某些原因无法应用所传送的参数。 Further, even if the MS transmission parameters to the mobile station, the mobile station may not be applied for some reason transmitted parameters. 因此,会出现这样的情况:一组新参数P'仅在网络侧合法,即由无线网络控制器RNC和基站BS使用(假定新的L1参数集的同步正常无误),而移动台MS仍使用迄今为止合法的参数集P进行通信。 Thus, there will be such a situation: a new parameter set P 'only legitimate network side, i.e. the radio network controller RNC and the base station BS uses (assuming a new set of parameters L1 normal correct synchronization), but still using the mobile station MS P parameter set valid date communication.

显然,这会导致基站BS和移动台MS之间的参数失配。 Obviously, this will result parameter between the base station BS and the mobile station MS mismatch. 因此,这可能会导致移动台MS检测到无线链路故障。 Accordingly, this may cause the mobile station MS detects a radio link failure. 此外,在WCDMA中,即使到专用物理控制信道的同步正常,也无法再解码从移动台MS到基站BS(上行UL)的数据传输所使用的物理信道。 Further, in WCDMA, even normal to the synchronization dedicated physical control channel, it can not be re-decoded from the mobile station MS to the physical channel base station BS (uplink UL) data transmission is used.

上述现象将会导致故障,如果参数失配无法纠正,故障又会导致通信(呼叫)丢失(或者无法建立)。 The above phenomenon will lead to failure, if the parameter mismatch can not be corrected, will lead to the failure of communication (call) is lost (or can not be established).

此外,在最少的情况下,网络侧一般能在一个交织周期之后发现故障(交织表示了将脉冲串差错变成随机差错的一种差错控制技术,如同在例如Y.Akaiwa所著以下文献第287页所描述的那样:“Introduction To Digital Mobile Communication”,John Wiley &Sons,New York,USA,1997)。 Further, in a minimum, the network side is generally found after a failure interleaving period (expressed interleaving the error burst error into a random error control technique, as written in the literature e.g. Y.Akaiwa 287 as described on page: "Introduction to Digital Mobile Communication", John Wiley & amp; Sons, New York, USA, 1997). 但是,在作出涉及信道状态的决定时,需要多个交织周期。 However, when the decision relates to channel state, it requires a plurality of interleaved cycles. 因此,只能在检测到故障之后才能将信道故障通知给无线网络控制器。 Thus, the channel can only be a failure notification to the radio network controller after a fault is detected.

因此,本发明的一个目的是提供一种方法和相应的设备,用于在无线通信网的第一无线收发信机设备和第二无线收发信机设备之间指派通信信道,它消除了上述缺陷。 It is therefore an object of the present invention is to provide a method and corresponding apparatus, for assigning a wireless communication channel between a first wireless communication network and a second transceiver device wireless transceiver device, which eliminates the aforementioned drawbacks . 本发明尤其旨在提供一种网络侧无线信道重构的无缝恢复的方法和设备。 In particular, the present invention aims to provide a method and apparatus to restore a seamless network side radio channel reconstruction.

该目的通过在无线通信网的第一无线收发信机设备和第二无线收发信机设备之间指派通信信道的一种方法实现,该方法包括以下步骤:监控指派的第一通信信道的参数,检测改变所述第一通信信道的所述被监控参数的请求,在检测到改变参数的请求之后,激活第二通信信道用于所述第一和所述第二无线收发信机设备之间的通信,解码这两个通信信道,判断是否已成功解码了所述附加激活的第二通信信道,在判断出已成功解码了所述第二通信信道之后,释放所述第一通信信道,仅通过所述第二通信信道继续通信。 This object is achieved by a method for assigning a wireless communication channel between a first wireless communication network and a second transceiver device wireless transceiver device to implement, the method comprising the steps of: a first communication parameters to monitor the assigned channel, detecting the change of the first communication channel request parameters to be monitored, after detecting a request to change the parameters for activating a second communication channel between said first and said second radio transceiver device after the communication, the decoding both communication channels, determining whether the successfully decoded additional activation of the second communication channel has been successfully decoded is judged in said second communication channel, said first communication channel is released, only by said second communication channel continue the communication.

此外,以上目的通过在无线通信网的第一无线收发信机设备和第二无线收发信机设备之间指派通信信道的一种设备实现,包括监控装置,用于监控指派的第一通信信道的参数,检测装置,用于检测改变所述第一通信信道的所述被监控参数的请求,激活装置,用于在检测到改变参数的请求之后,激活第二通信信道用于所述第一和所述第二无线收发信机设备之间的通信,解码装置,用于解码这两个通信信道,判断装置,用于判断是否已成功解码了所述附加激活的第二通信信道,释放装置,用于在接收到已成功解码了所述第二通信信道的判断结果之后,释放所述第一通信信道,仅通过所述第二通信信道继续通信。 Further, the above object is achieved by an apparatus for assigning a communication channel between a first wireless communication network radio transceiver device and the second wireless transceiver devices implemented, including monitoring means for monitoring a first communication channel assigned to parameter detecting means for detecting a change of the first communication channel request parameters to be monitored, the activation means, after detecting the request for change of parameters, activates the second communication channel for the first and communications decoding means between the second wireless transceiver apparatus for decoding both communication channels, judging means for judging whether the decoding has been successfully activated the additional second communication channel, the release means, after receiving a successful decode for the result of the determination in the second communication channel, said first communication channel is released, only the second communication channel to continue communication.

本发明的进一步特点在各相关的权利要求中定义。 Further features of the present invention are defined in the relevant claims. 基于按照本发明的方法和设备,可以实现以下优点和改进:(1)在出现参数改变时,物理L1层的无线参数P可以安全地重新定义。 The method and apparatus of the present invention can achieve the following advantages and improvements based on: (1) in case of parameter changes, the physical layer L1 P radio parameters can be redefined safely.

(2)可以减少丢失的呼叫率,即丢失呼叫的数量。 (2) can reduce the call loss rate, i.e., the number of lost calls.

(3)在按照WCDMA原理工作的网络中,可以迅速地,很可能在单个交织周期之后,检测出无线信道重构时出现的故障。 (3) operating in accordance with WCDMA network in principle, it can be quickly, probably after a single interleaving period, when a failure is detected wireless channel reconstruction. 此外,(故障)无线信道重构的恢复不会引起上行方向UL传输的任何数据丢失。 In addition, (a fault) the radio channel to recover any data reconstructed without causing loss of the uplink direction UL transmission.

因此,减少了网络控制器的无线资源的处理负荷。 Thus, reducing the processing load of the radio network resource controller.

下面结合附图描述本发明,在附图中:图1概要地示出了无线通信网络的部件;图2(由图2A & 2B组成)的流程图说明了按照本发明一种实施例的可调设备的方法和操作。 The present invention is described below in conjunction with the accompanying drawings, in which: FIG 1 schematically shows components of a wireless communication network; (FIG. 2A & amp; 2B composition) of FIG. 2 illustrates a flowchart of one embodiment according to the present invention. adjustable apparatus and method of operation.

按照本发明,如果空中接口参数集P改变(或被改变)成第一层的新参数集P'(是指按照OSI/ISO通信层模型的第一层),已指派的(“原”)第一层上行和/或下行参数在基站BS中保持活跃,直至移动台MS成功启用了新的通信信道。 According to the present invention, if the air interface change parameter set P (or changed) to a new set of parameters of the first layer P '(means in accordance with OSI / ISO layer a first communication layer model), has been designated ( "original") a first layer of uplink and / or downlink parameter in the base station BS remain active until the mobile station MS successfully enabled a new communication channel.

换句话说,例如在上行传输(UL)中,为新的通信信道UL2激活基站BS侧的新的硬件资源,而不需要释放为分配给前一(“原”)无线通信信道UL1的资源,UL2的特征由新参数集P'指定。 In other words, for example, in the uplink transmission (UL), the hardware resources for the new base station BS side UL2 activate new communication channel, without releasing the resources allocated to the previous ( "original") of a wireless communication channel UL1, characterized in UL2 'specified by the new parameter set P. 更精确地讲,存在一个从移动台MS到基站BS的物理信道传输,但基站BS侧有两个接收单元R,它们分别利用各移动台MS的不同的第一层参数工作。 More precisely, there is a MS from the mobile station the physical channel transmission base station BS, the base station BS side two receiving units R, respectively, with different parameters of the work of the first layer of the mobile station MS. 这样,基站BS中仅有一个接收单元R可以接收移动台MS的信号,它可以提供正确的解码结果。 Thus, only one base station BS receiving unit R may be the mobile station MS receives a signal, it can provide a correct decoding result.

如果在下行DL方向上,新参数和原第一层参数都保持活跃,则意味着有两个传输无线通信信道(基站的发射机单元)活跃。 If the DL in the downlink direction, the new parameters and the original parameters of the first layer remain active, it means that there are two transmitting wireless communication channel (the base station transmitter units) active. 图1概要示出了以上解释的这种情况。 1 schematically shows such a situation as explained above. 无线网络控制器设备RNC与无线网络的基站BS通信,并控制该基站。 BS base station radio communication network with a radio network controller device RNC and the base station control. 但是,应当注意到,实际上无线网络控制器设备RNC控制网络的多个基站。 However, it should be noted that, in fact, the radio network controller device RNC controls a plurality of base stations of the network. 基站BS与出现在基站小区中的移动台MS通信。 The base station BS MS communicates with the base station appears in the cell the mobile station.

具体而言,从移动台MS到基站BS的上行方向UL上的数据传输通过上行通信信道(使用参数集P的UL1,或者使用参数集P'的UL2)实现。 Specifically, the MS data transmission from the mobile station to the base station BS uplink UL direction through the upward communication channel (UL1 using the parameter set P, or a parameter set P 'of UL2) implementation. 在给出的例子中,所用的上行通信信道UL1、UL2在第一层(L1)参数P、P'上有所不同。 In the example given, the upward communication channel used UL1, UL2 in the first layer (L1) parameters P, the different P '. 从基站BS到移动台的下行方向DL上的数据传输通过下行通信信道DL。 From the base station BS downlink data transmission on the DL to the mobile station via a downlink communication channel DL. 在基站侧,上行方向上传送的数据的接收由基站中两个活跃的接收单元实现(图1中由R标记),每个单元分别使用参数集P、P'接收。 Receiving data transmitted on the base station side, the base station in the uplink direction is realized by two active receiving unit (labeled by R in FIG. 1), receives each unit using the parameter set P, P '.

应当理解,给出的情况仅是一个例子。 It should be appreciated that, given merely one example. 商用基站可以有多个信道,分别超过两个上行和/或一个下行信道,图仅示出了可以实现本发明的基站的最小需求。 Commercial base station may have a plurality of channels, respectively, more than two upstream and / or downstream channel, the figure shows only the minimum requirements for a base station may be implemented according to the present invention. 本发明仅需要基站具有足够的硬件资源,能够为连接临时分配附加数量(例如双倍)的硬件资源。 The base station of the present invention need only have a sufficient hardware resources to an additional number (e.g. double) for connecting temporary assignment of hardware resources. 如果多于一个移动台MS同时与基站BS通信,则应当有足够的硬件资源和通信信道,使得可以为每个移动台MS指派两个不同的信道用于通信,在基站BS的小区中,这两个信道不同时用于通信。 If more than one mobile station MS communicates with the base station BS at the same time, it should have enough hardware resources and communication channels, such that each mobile station MS may be assigned two different channel for communication, the base station BS in the cell in which two channels are not simultaneously used for communication. 但是,为了进一步解释方便,以下描述仅针对单个移动台。 However, for convenience of further explanation, the following description is only for a single mobile station.

图2给出的流程图说明了可调设备的方法和操作。 Figure 2 shows a flow chart illustrates a method and apparatus tunable operation. 该设备(图1中未示出)形成图1所示的基站BS的部件。 The apparatus (not shown in FIG. 1) forming part of the base station BS 1 shown in FIG.

现在参看图2A,整个过程开始于步骤S1。 Referring now to Figure 2A, the process begins at step S1. 在后续步骤S2中,检查移动台MS和基站BS之间的上行通信信道,例如UL1,是否活跃。 In a subsequent step S2, it is checked uplink communication channel between a base station and a mobile station MS the BS, UL1 and for example, is active. 这种上行通信信道由基站BS中可用的至少两个接收单元R中的一个接收,接收单元在图1所示例子中标记为R[UL1(P)]。 Such an upward communication channel received by the base station BS is available at least two receiving units in R, the receiving unit in the example shown in FIG. 1 labeled as R [UL1 (P)]. 如果没有检测到活跃的上行通信信道(步骤S2中的NO),则过程重复,直至检测到活跃的第一上行通信信道UL1(步骤S2中的YES)。 If it detects no active uplink communication channel (NO in step S2), then the process is repeated until an active first uplink communication channel UL1 (YES in step S2). 响应于这种检测,在步骤S3,监控所述通信信道UL1的L1参数集P。 In response to such detection, at step S3, the monitoring of the communication channel UL1 L1 of the parameter set P. 在步骤S4中,检测无线网络控制器RNC侧是否同时指令改变前一监控的参数P。 In step S4, the radio network controller RNC side detecting whether an instruction to change the parameters of the previous simultaneously monitored P. 如果没有检测到参数改变请求/指令(步骤S4中的NO),则上行通信中维持(步骤S5)通信信道UL1以前指派/激活的接收单元R[UL1(P)](利用第一层参数集P接收),流程返回到步骤S3。 Previously, if not detected parameter change request / instruction (NO in step S4), the uplink communication is maintained (step S5) a communication channel UL1 assignment / active receiving unit R [UL1 (P)] (with the first layer parameter set P received), the flow returns to step S3. 但如果检测到L1参数集的改变请求,即需要为新的通信信道UL2激活新参数P',则过程前进到步骤S6。 However, if a change is detected L1 parameter set request, i.e., the need for a new communication channel UL2 activate the new parameter P ', then the process proceeds to step S6. 在步骤S6中,在移动台MS和基站BS之间的上行通信中激活通信信道UL2(利用第一层参数集P'接收)的附加的新接收单元R[UL2(P')]。 In step S6, activation of the communication channel UL2 in an uplink communication between a mobile station MS and base station BS (first layer using the parameter set P 'received) additional new reception unit R [UL2 (P')]. 应当注意到,在这种情况下,通信信道UL1和UL2的基站BS的接收单元R同时活跃,同时从移动台MS到基站BS仍只有一个物理信道传输。 It should be noted that, in this case, the communication channel UL1 UL2 base station BS and the reception unit R simultaneously active, while the base station to the mobile station MS from the BS still has only one physical channel transmission.

在后续步骤S7中,为通信信道UL1和UL2的L1参数(P,P')解码上行物理信道上传送的数据。 In a subsequent step S7, the communication channel UL1 and UL2 of L1 parameters (P, P ') decodes the uplink data transmission on a physical channel. 此后,在步骤S8中,判断利用通信信道UL2上附加激活的接收单元传输的数据的解码是否正确。 Thereafter, in step S8, the decoded data is determined using an additional activation unit for transmission received on the communication channel UL2 is correct. 如果规定通信信道UL2的L1参数集的传输数据的解码失败,即判断解码出错,(步骤S8中的NO),则该方法进入分支,在步骤S9中继续(图2B)。 If the predetermined data transmission L1 decoding parameter set fails the communication channel UL2, i.e. determination is decoded in error, (NO in step S8), the method proceeds branch continues (FIG. 2B) in step S9.

现在参看图2B,在步骤S9中确定表征通信信道UL1的L1参数集的传输数据的解码是否仍成功。 Referring now to decode the transmission data 2B, the determined set of parameters characterizing L1 communications channel UL1 in step S9 whether the still successful. 如果确定利用定义通信信道UL1的参数集P解码传输数据不成功(步骤S9中的NO),则流程进行到步骤S10。 If it is determined using the parameter set defines communications channel UL1 transmission of data is not successfully decoded P (S9 NO in step), the flow proceeds to step S10. 在步骤S10中,可以证实通信(呼叫)已被终止或丢失,因为利用定义通信信道UL1、UL2的参数集都不能解码数据。 In step S10, it was confirmed that the communication (call) has been lost or terminated, as defined using the communication channel UL1, UL2 set of parameters can not decode the data. 但如果利用通信信道UL1的参数集解码成功(步骤S9中的YES),则流程进行到步骤S11。 However, if a communication channel using the parameter set decoded UL1 successful (YES in step S9), the flow proceeds to step S11. 在步骤S11中,利用原先为信道UL1(具有“原”参数P)指派的参数继续通信。 In step S11, using the previously assigned a channel UL1 continue the communication parameters (with the "original" parameter P). 即,继续使用接收单元R[UL1(P)],同时释放单元R[UL1(P')],使其又处于空闲状态。 That is, continue to use the receiving unit R [UL1 (P)], while the releasing unit R [UL1 (P ')], and it is in an idle state. 这确保了不会因无法成功建立具有新参数P'的新通信信道UL2而丢失数据。 This ensures that no inability to successfully establish a new communication channel UL2 has a new parameter P 'of lost data. 此后,在步骤S12中,通知无线网络控制器RNC无法建立新信道UL2用于移动台MS和基站BS之间的通信。 Thereafter, in step S12, notifies radio network controller RNC can not create a new channel UL2 for communication between the mobile station MS and base station BS. 无线网络控制器RNC可以采取另一适当的行动来改变参数集,利用改动后的参数集建立新的通信信道。 Radio network controller RNC can take appropriate action to change another parameter set, establish a new communication channel using the parameter set changes.

再次参看图2A,如果利用表示通信信道UL2参数解码发送的数据成功,即判定解码正确(步骤S8中的YES(是)),则该方法流继续到步骤S13。 Referring again to FIG. 2A, data indicating if the use of a communication channel UL2 transmitted successfully decoded parameters, i.e., the correct decision decoding (YES in step S8 (Yes)), the method flow proceeds to step S13. 在步骤S13,释放采用通信信道UL1的参数P的前一指派/活跃接收单元R[UL1(P)],移动台MS和基站BS之间的通信利用通信信道UL2继续,即接收单元R使用通信信道参数集P'进行接收。 In step S13, the release using previous assigned parameter P communication channel UL1 to / Active reception unit R [UL1 (P)], a communication use between the mobile station MS and base station BS communication channel UL2 continues, i.e., the receiving unit R using the communication channel parameter set P 'reception. 这样,通信信道UL2是指派的通信信道,流程返回到步骤S2。 Thus, the communication channel UL2 is assigned a communication channel, the flow returns to step S2. 如果指令了其它参数,则重复该处理。 If the other parameters of the command, the process is repeated.

通过以上描述,可以清楚地知道从移动台到基站只有一个物理信道传输,但基站中为同一移动台MS激活了具有不同第一层参数(P,P')的两个接收单元,图1概要示出了这种情况。 By the above description, it is clear from the mobile station to the base station knows only one physical channel transmission, but the base station is activated in the receiving unit having a first layer two different parameters (P, P ') of the MS for the same mobile station, FIG. 1 schematically this situation is shown. 基站侧的这两个接收单元中只有一个接收可以正确解码的信号。 Both the base station side reception unit receiving only one signal may be correctly decoded.

需要注意,尽管图2A的步骤S13提到将UL2设置成UL1,但这只是为了解释只涉及两个通信信道的情况。 Note that, although the step S13 of FIG. 2A will be referred UL1 and UL2 provided, this is for explanation relates to the case where only two communication channels. 通信信道UL2的特性当然由它的指定参数集P'来定义。 Characteristics of the communication channel, of course, UL2 'is defined by its assigned set of parameters P.

通过以上描述,可以清楚地知道按照本发明,基站BS侧总选择能够提供连续解码的L1帧的通信信道。 By the above description, will be clear to the present invention, the base station BS capable of providing a continuous side header select a communication channel decoded frames L1. 具体而言,在成功重构情况下,不需要将基站处理的临时资源激活和去活的整个重构过程都通知无线网络控制器RNC。 Specifically, in the case of successful reconstruction, the base station does not need to process the temporary resource activation and deactivation of the entire reconstitution process will notify the radio network controller RNC. 因此,减少了无线网络控制器RNC的处理负荷。 Thus, reducing the processing load of the radio network controller RNC. 只有在以新参数建立新的通信信道失败,而维持原参数以使数据和呼叫不会丢失时,才涉及无线网络控制器RNC。 Only when creating a new communication channel failure with the new parameters, while maintaining the original data and the parameters that the call is not lost, it relates to a radio network controller RNC. 整个过程对移动台是透明的。 The entire process is transparent to the mobile station.

以上针对仅提供两个上行信道(接收单元R)的基站的例子描述了本发明。 Only two examples provided above for the uplink channels (the receiving unit R) of a base station described in the present invention. 但是,如果可以使用多于两个上行通信信道UL,那么在步骤S6中必须决定为新参数选择哪个信道。 If, however, may use more than two uplink communication channel UL, it must decide which channel is selected as a new parameter in step S6.

前面提过,本发明要求指令改变其参数集的每个通信信道配备有附加的硬件资源(例如在考虑上行UL传输时,是接收单元R)。 Mentioned earlier, the present invention is to change its parameter set request command of each communication channel is equipped with additional hardware resources (e.g., in consideration of the uplink UL transmission, a reception unit R). 但是,从避免提供大量通常无用的硬件资源角度来看,可能不希望为所有可用信道固定提供两倍数量的硬件资源。 However, to avoid unnecessary to provide a large amount of hardware resources generally perspective, you may not wish to provide twice the number of fixed hardware resources for all available channels. 出于实际因素考虑,可以考虑在通信信道参数集的请求改变可能足够的情况下,为每个基站附加地激活单个通信信道。 For practical considerations, consider the case where a sufficient change may request a communication channel parameter set, additionally activate a single communication channel for each base station. 其原因是,可以认为基站BS侧同时指令改变通信信道参数集的可能性相当低。 The reason is the possibility that the base station BS side can simultaneously change the communication channel instruction parameter set quite low.

为此,可以采取措施确保基站BS的所有可用通信信道中有至少一个通信信道可以被指派用于步骤S3到S13。 To this end, measures can be taken to ensure that all communication channels available for the base station BS with at least one communication channel may be assigned for steps S3 to S13.

具体而言,可以规定在检测到已指派的通信信道(正在进行的呼叫)的数量已到达可用通信信道的总量减1时,禁止建立移动台MS和基站BS之间的新的通信。 Specifically, a predetermined amount is detected in the number of communication channels (ongoing call) has reached the assigned communication channel when the available minus 1, prohibit the establishment of a new communication between the mobile station MS and base station BS.

以上给出的本发明的描述主要考虑了上行传输信道。 Description of the invention given above mainly considered an uplink transport channel. 但是,下行传输资源也可以利用类似于以上描述的方式激活。 However, the downlink transmission resource may be activated using a manner similar to that described above. 但是,这需要将两个信道所引起的干扰考虑在内,并且需要无线资源调度需求的允许,因为在CDMA中,所有的信号都同时发送且相互干扰。 However, it is necessary to consider interference caused by the two inner channels, and the need to allow radio resource scheduling demands, as in the CDMA, all signals are transmitted simultaneously and interfere with each other.

应当理解,以上描述和附图仅用于通过例子说明本发明。 It should be understood that the above description and drawings are merely illustrative of the invention by way of example. 在后附权利要求书的范围内,本发明的优选实施例可以有所变化。 Within the scope of the appended claims, a preferred embodiment of the present invention may vary.
