Description

改变业务信道速率提高蜂窝通信系统业务容量 Traffic channel rate changes to improve traffic capacity of a cellular communication system

发明领域本发明与提高蜂窝无线电通信系统的业务容量有关,具体地说,涉及在需要额外的业务容量时通过改变所请求的或初始选择的业务信道速率来提高业务容量的技术。 Field of the Invention The present invention to improve the cellular radio communications system traffic capacity related, in particular, relates to a technique for improving traffic capacity over the traffic channel rate or an initial selection of the requested change in the need for additional traffic capacity.

发明背景和概述在全球数字移动通信系统(GSM)中,为语音编码器规定了两种比特率:全速率和半速率。 BACKGROUND AND SUMMARY OF THE INVENTION In a global digital mobile communication system (GSM), a speech encoder provides two bit rates: full rate and half rate. 全速率相应于13kbits/s(千比特/秒)的比特率,而半速率相应于6.5kbits/s的比特率。 Full rate corresponds to 13kbits / s (kilobits / second) bit rate, and half rate corresponds to a bit rate 6.5kbits / s of. 在GSM系统中的业务信道可以支持一个全速率语音呼叫或两个半速率语音呼叫。 A traffic channel in the GSM system can support one full rate speech call or two half rate speech calls. 语音编码显著地降低了无线电接口的比特率(高比特率要占用太多的频谱),但是仍能提供可接受的语音质量。 Speech coding significantly reduces the bit rate of the radio interface (higher bit rates take up too much of the spectrum), but still providing acceptable speech quality. 通常,语音编码发送的是有关语音的信息而不是语音本身,接收方可以根据这信息恢复语音信号。 Typically, speech coding is transmitted information about the speech itself, rather than voice, the receiver can recover the voice signal in accordance with this information.

GSM还采用时分多址(TDMA),将每个射频载波分成八个时隙(TS)。 GSM also employs time division multiple access (TDMA), each radio carrier is divided into eight time slots (TS). 一个TDMA帧内的一个时隙称为一个物理信道,而每对频率载波包括八个物理信道。 A timeslot one TDMA frame is called a physical channel, and each pair of frequency carriers includes eight physical channels. 语音及其他信息在映射为物理时隙信道的逻辑业务信道(TCH)上发送。 Speech and other information is transmitted on a physical slot is mapped logical channel traffic channel (TCH). 在全速率业务信道内,一个用户分配使用单个物理信道/时隙。 In the full rate traffic channel, a user is assigned a single physical channel / time slot. 对于半速率业务信道情况,两个移动台共享同一个物理信道/时隙,两个移动台交替使用分配的这个时隙。 For the case of half-rate traffic channels, two mobile stations share the same physical channel / time slot, two mobile stations assigned to this time slot are used interchangeably.

移动电话系统运营方生活在一个高度竞争的世界。 Mobile telephone system operators to live in a highly competitive world. 为了得到成功,一个移动电话系统运营方必须提供:覆盖--任何地方都能建立呼叫容量--任何时候都能建立呼叫质量--通话清晰、不受打扰和不中断。 In order to get success, a mobile telephone system operators must provide: coverage - anywhere establish call capacity - at all times to establish a call quality - Call clear, undisturbed and uninterrupted.

本发明针对的是容量。 The present invention is directed to capacity.

提高容量的传统方法是为基站配备尽可能多的收发机,投入大容量基站控制器。 Traditional methods to improve the capacity of the base station is equipped with as many transceivers, the base station controller into a large capacity. 虽然这在业务需求在时间上是均匀分布的人口稠密区是一个彻底的策略,但是在只是在一些短时间内业务需求高的地区,如在早晨和傍晚期间是高峰的某些街道,这种策略就不大合理了。 While this densely populated area in the business needs over time is evenly distributed is a thorough strategy, but in just a short time in some high-demand areas of business, such as in the morning and during the evening peak is certain streets, such strategy is not a reasonable large. 较困难的问题是怎样有效和经济地满足临时性的大业务量的需求。 The more difficult question is how to efficiently and economically meet temporary high traffic demands.

因此,本发明的主要目的是动态地提高系统容量,以有效和经济的方式满足临时性的大业务量的需求。 Therefore, a primary object of the present invention to dynamically increase system capacity, efficient and economical way to meet temporary high traffic demands.

本发明的另一个目的是增强提供需要全速率业务信道的连接的服务的能力。 Another object of the present invention is to enhance the ability to provide services that require a full rate traffic channel connection.

现在有一些移动台能以不同的比特率进行无线电通讯,而且将来这样的会有更多。 There are a number of mobile stations capable of radio communications at different bit rates, and so there will be more in the future. 为了说明本发明起见(并不是说本发明就局限于所假设的情况),一些移动台假设为能够在全速率和半速率两种信道上进行收发。 For purposes of illustration of the present invention (not to say that the present invention is limited to the case where it is assumed), some of the mobile station is assumed to be able to send and receive full-rate and half rates of the two channels. 这样的移动台称为具有“双速率”能力。 Such a mobile station referred to as having "dual rate" capability. 双速率移动台通过一个初始信道请求消息或者也可能在定期的登记消息中向蜂窝网表明它们的双速率能力。 The dual rate mobile station an initial channel request message or may indicate their dual rate capability to the cellular network at periodic registration messages. 较高速率的信道可以在业务条件有利的情况下使用,而半速率信道在出现临时性的大业务量情况期间使用。 A higher rate channel can be used in favorable traffic conditions, and the half-rate channel in the event of use during temporary high traffic conditions.

本发明按照以下方法提高蜂窝无线电通信系统的容量。 The present invention increases the capacity of the cellular radio communications system in accordance with the following method. 开始,建立一个高速率的业务信道,用来与位于一个特定小区内的一个移动台进行通信。 Starts, a traffic channel is established high rate, used to communicate with is located within a particular cell of a mobile station. 然后,确定这个小区的当前通信业务负荷。 Then, determining a current traffic load of the cell. 如果确定的通信业务负荷超过一个门限,就将一个双速率移动台用来进行通信的高速率业务信道切换到在这个小区内可用的另一个低速率业务信道。 If the determined traffic load exceeds a threshold, the mobile station will be one pair of rate for high-rate traffic channel for communication is switched to another lower rate traffic channel available within the cell. 对于当前激活的这些业务信道,维护一个列有当前分配给那些双速率移动台的高速率业务信道的表。 For currently active traffic channels, that maintaining a table that lists the high-rate dual-rate traffic channel is currently assigned to the mobile station.

在从高速率业务信道切换到低速率业务信道前,确定是否允许这样的切换。 Before switching from the higher rate traffic channel to a low rate traffic channel, determining whether to allow such switching. 如果是,进行区内切换(intra-cell handover),最好切换到一个当前已经在支持另一个低速率呼叫的业务信道上。 If yes, the switching area (intra-cell handover), the current is preferably switched to a traffic channel is already supporting another lower rate call. 否则,分配任何可用的低速率业务信道。 Otherwise, assign any available lower rate traffic channel.

在呼叫建立时,如果小区内当前通信业务负荷超过门限,就为一个涉及双速率移动台的呼叫请求分配一个低速率业务信道。 In call setup, if the current traffic load in the cell exceeds the threshold, it relates to a dual rate mobile station call requests allocation of a low-rate traffic channel. 如果小区内通信业务负荷降低,就可以将一个因为通信业务负荷高开始建立的或者后来切换到低速率信道的呼叫切换到一个高速率信道上。 If the traffic load within the cell is reduced, since it may be a high traffic load the start switch to establish a call or a later low-rate channel is switched to a high-rate channel.

附图详细说明在以下说明中,为了能对本发明有彻底的了解提出了一些具体详细,诸如特定的实施例、硬件、技术等等,这些都是解释性的,而不是限制性的。 Detailed Description of the Drawings In the following description, in order to provide a thorough understanding of the present invention provides a number of specific details, such as particular embodiments, hardware, techniques, etc., these are illustrative, and not restrictive. 然而,熟悉这种技术的人员很清楚,本发明可以实际应用于具体细节与此不同的其他实施方式。 However, persons skilled in this art it is clear that the present invention can actually be applied to the specific details of various other embodiments of this embodiment. 例如,虽然本发明的一个具体实施例是以GSM蜂窝电话网为背景说明的,但熟悉该技术的人员可以理解,本发明可以在任何蜂窝电话系统内实现。 For example, although a specific embodiment of the present invention is a GSM cellular telephone network as described in the background, those skilled in the art will appreciate that the present invention may be implemented in any cellular telephone system. 在其他一些情况下,众所周知的方法、接口、设备和信令技术的详细说明都省去了,以免不必要的细节反而使本发明的说明模糊不清。 In some other instances, well-known methods, interfaces, devices and signaling techniques detailed description are omitted in order to avoid unnecessary detail but obscure the description of the present invention.

因为本申请可以适用于任何蜂窝电话通信系统,所以现在概括地说明本发明的第一典型实施例。 Since the present application may be applicable to any cellular telephone communications systems, it is now generally be described a first exemplary embodiment of the present invention. 图1这个流程图示出了改变信道速率例行程序(方框10)的各个步骤。 Figure 1 illustrates the flow channel rate change routine (block 10) of the respective steps. 假设通信业务负荷开始比较轻或者是中等,因此按照标准的信道请求和指配过程为在一个特定的小区、扇区或其他位置区内的移动台呼叫建立第一速率的业务信道(方框12)。 Start assumed traffic load is relatively light or medium, so according to the standard channel request a traffic channel (block 12 and the assignment process to the mobile station in a particular cell, a sector or other area of ​​the call set-up position of the first rate ). 然后,确定这个小区或位置区内的通信业务负荷(方框14)。 Then, the traffic load is determined (block 14) of the cell or location area. 在方框16作出判决,确定这个小区或位置区的通信业务负荷是否超过一个门限,即确定业务需求是否已临时增大。 In decision block 16 to determine whether the traffic load of the cell or location area exceeds a threshold, i.e. to determine whether the service demand has temporarily increased. 如果不是,继续如建立时那样进行移动通信(方框17)。 If not, the mobile communication continues (block 17) is established as above. 然而,如果通信业务负荷超过一个门限,就将一个正在一个业务信道上以第一速率进行的双速率移动台的通信切换到另一个业务信道上以较低的第二速率进行通信(方框18)。 However, if the two-rate traffic load exceeds a threshold, it will be a traffic channel is performed at a first communication rate of the mobile station to switch to another traffic channel in a second lower rate communication (block 18 ). 此外,新的对双速率移动台的呼入就作为低速率呼叫而不是高速率呼叫建立,直到通信业务负荷降低到门限以下。 In addition, the new dual-rate of the mobile station to an incoming call as a high rate instead of a low-rate call setup until the traffic load decreases to below the threshold. 如果通信业务负荷显著降低,可以将一些呼叫随意地从低速率业务信道切换到可用的高速率业务信道(方框17)。 If the traffic load decreases significantly, calls may optionally be switched from a number of low rate traffic channels to available higher rate traffic channels (block 17).

因此,本发明通过利用一些在一个小区内工作的双速率移动台的低速率能力提供了临时提高这个小区的业务容量的能力。 Accordingly, the present invention provides the ability to temporarily increase the traffic capacity of the cell to use some operating in the dual rate mobile station within a cell of the low-rate capability. 因为这些通信连接只是在服务小区内移动,即区内切换,所以并不增大干扰电平,犹如采用切换到其他小区的越区切换会出现的那样。 Since only mobile communication connections in the serving cell, i.e. handover area, the interference level does not increase, if handover to another cell using handover occurs as. 本发明的另一个优点是不需要附加硬件。 Another advantage of the invention is that no additional hardware. 不需要为保证有足够的能力应付临时性的大业务量需求配置一些备用而通常不用的基站收发机。 Does not need to ensure sufficient capacity to cope with temporary high traffic demands some spare usually arranged without a base station transceiver. 本发明的又一个优点是移动通信网络运营方可以通过适当改变通信业务负荷门限值控制各个小区对业务需求的处理。 A further advantage of the invention is a mobile communications network operator can control the value of the respective cell processing business needs by appropriately changing the traffic load threshold. 适当取值的门限可以保证在大业务量期间只有最少数的具有双速率能力的移动台受到区内切换到低速率业务信道的影响。 Appropriately-valued threshold ensures that only a high traffic during the minimum number of mobile stations having dual rate capability are affected zone switching to a low rate traffic channel. 本发明还在呼叫建立时根据当前小区通信业务负荷情况选择具体业务信道的信道速率,使得在大业务量期间使用低速率建立涉及双速率移动台的通信,进一步提高业务容量。 The present invention is also selected to establish the call when the particular traffic channel rate channel according to the current cell traffic load situation, so that the establishment of a communication involving dual rate mobile station using a low rate during high traffic, to further increase traffic capacity.

下面将说明应用于基于GSM的蜂窝通信系统的本发明的第二典型实施例。 The following will be described a second exemplary of the present invention is applied to GSM-based cellular communication system according to an embodiment. 然而,熟悉该技术的人员可以理解,本发明并不局限于基于GSM的蜂窝通信系统。 However, one skilled in the art will appreciate that the present invention is not limited to GSM-based cellular communication system.

图2以功能方框图的形式例示了一个典型的基于GSM的蜂窝通信系统30。 Figure 2 illustrates the form of a functional block diagram of a typical GSM-based cellular communication system 30. 网关移动业务交换中心(GMSC)36将这个蜂窝通信网对接到其他远程通信网,包括公众电话交换网(PSTN)32、互联网34、其他蜂窝网,以及诸如综合业务数字网(ISDN)之类的其他类型的通信网。 Gateway mobile services switching center (GMSC) 36 to the cellular communication network to receive other remote communication networks, including the public switched telephone network (PSTN) 32, Internet 34, other cellular networks, as well as Integrated Services Digital Network (ISDN) or the like other types of communication networks. 网关移动业务交换中心36与一个或多个移动业务交换中心(MSC)38连接。 Gateway mobile services switching center 36 is connected to one or more mobile services switching center (MSC) 38. 每个移动业务交换中心38与一个或多个基站控制器(BSC)42连接。 Each mobile services switching center 38 is connected to one or more base station controllers (BSC) 42. BSC处理所有的包括对基站44的管理和遥控的与无线电有关的操作,以及处理包括切换的对移动台46的连接。 BSC handles all management includes a base station and a remote radio related operations 44, and the processing including handover connection to the mobile station 46. 每个BSC42与多个基站(BS)44连接,这些基站44与移动无线电台(MS)46进行通信。 Each of the plurality of base stations and BSC42 (the BS) 44 connected to these base stations 44 communicate with a mobile radio station (MS) 46.

网关TYISC 36是在移动无线电通信网内对移动用户呼叫的接口点。 Gateway TYISC 36 is the interface point in the mobile radio network to the mobile user's call. 虽然为了清晰起见GMSC 36示为一个独立的节点,但是它也可以设置成与MSC 38一起。 Although the GMSC 36 is shown for clarity as a separate node, but it can also be provided together with the MSC 38. 每个移动业务交换中心38执行与涉及移动台(MS)46的呼叫关联的电话交换操作,包括与其他电信网32和34对接和为移动台发起的呼叫进行路由选择。 Each mobile services switching center 38 executes a telephone call directed to a mobile station associated with (MS) 46 of the switching operations, including docking with other telecommunications networks 32 and 34 and the mobile station originated call routing.

每个MSC38配有一个访问用户位置寄存器(VLR)40,它包括一个数据库,其中存有它所配合的MSC38需要的临时用户信息,以便为在这个MSC的业务区内的移动台提供服务。 Each MSC38 with a visitor location register (VLR) 40, which includes a database of user information stored therein temporary MSC38 need it fit to provide services in the mobile station within the service area of ​​the MSC. 通常,在一个移动台进入一个访问网或业务区时,它要向VLR40登记。 In general, when a mobile station enters an access network or service area, it was about to VLR40 registration. 然后,VLR40向这个移动台的归属用户位置寄存器(HLR)41请求和接收有关这个漫游移动台的数据,存储起来。 Then, the VLR 40 requests the home location register of the mobile user station (HLR) 41 and receives data about the roaming mobile station, and stored. 结果,在这个访问移动台涉及到呼叫时,VLR40就已经具有建立呼叫所需的信息。 As a result, the mobile station when it comes to access to the call, VLR40 already has the information needed to establish the call. 虽然VLR40可以是一个独立的节点,但是最好与它所配合的MSC集成在一起,以省去两个节点之间的信令交换。 Although VLR40 may be a separate nodes, but it is preferably integrated with the MSC fitted together, eliminating the need to exchange signaling between the two nodes.

归属用户位置寄存器(HLR)41是一个存储和管理用户业务预约情况的数据库节点。 A home location register (HLR) 41 is a database node that stores and manages the user service subscription situation. 为每个"归属"移动用户,HLR41存有永久性的用户数据,例如在PSTN编号计划中唯一标识移动电话机的移动台ISDN号码(MSISDN),以及分配给每个移动用户、在移动网内用于呼叫的唯一标志的国际移动用户标志(IMSI)。 For each "home" mobile subscriber, HLR41 there permanent user data, such as mobile station ISDN number uniquely identifying the mobile phone (MSISDN), and assigned to each mobile user in the PSTN numbering plan, within the mobile network unique identifier for the mobile subscriber international call flag (IMSI). 所有与网络有关的用户信息都接至IMSI。 All information related to the network users are connected to the IMSI. HLR41存有一个业务表,列出了核准使用的移动用户和与当前为移动用户服务的VLR40的地址相应的当前用户位置号码。 HLR41 there a service table that lists mobile user and VLR40 approved for use with the current address of the service to the mobile subscriber corresponding to the current user location number.

确定了服务MSC/VLR(在归属网或访问网内的),对移动台46的呼叫就通过服务MSC传送给与被叫移动台当前所在小区配合的基站44。 Determining service MSC / VLR (home network or in the visited network), the mobile station 46 calls the called mobile station on the given station is currently located in the cell with the serving MSC 44 by transmitting. 利用众所周知的已确定的协议和形成文件的各种GSM标准中的过程,通过基站44与移动台46之间的无线电接口建立呼叫连接。 Protocol has been determined using known formation and various documents in the GSM standard, the radio between the mobile station 46 through the base station to establish a call connection interface 44.

在呼叫建立期间,根据有关可用信道的特性,在本发明中特别还根据移动台的能力,为基站与移动台之间的无线电连接分配逻辑业务信道。 During call setup, according to the characteristics of the available channels, in accordance with the present invention, particularly also the ability of the mobile station, the logical connection is assigned a radio traffic channel between the base station and the mobile station. 在连接已经通过一个分配的业务信道(例如一个TDMA时隙)建立后,对信号强度和语音质量进行监测,监测结果送到BSC,BSC根据那些报告可以启动连接切换。 After a connection has been established through the assigned traffic channel (e.g. a TDMA time slot), the signal strength and voice quality monitoring, the monitoring results to the BSC, BSC may initiate a connection switching based on those reports.

在发起呼叫时,BSC为移动台分配一个可用的业务信道(TCH)。 When initiating a call, BSC allocate an available traffic channel (TCH) to a mobile station. 在当前的CSM系统中,一个业务信道(TCH)可以支持单个全速率的通信(如在图3的50所示),也可以支持两个半速率的通信(如在图3的22和24所示)。 CSM in the current system, a traffic channel (TCH) may support a single full rate communication (e.g., 50 shown in FIG. 3), it may also support two half rate communications (such as 22 and 24 in FIG. 3 shown). 典型的全速率通信相应于比特率为13kbits/s,而典型的半速率通信相应于比特率为6.5kbits/s。 Typical full rate communication corresponds to a bit rate of 13kbits / s, while the typical half rate communication corresponds to a bit rate of 6.5kbits / s. 当然,全速率业务信道是指一个当前支持单个全速率呼叫的业务信道,而半速率业务信道是指一个当前支持一个或两个半速率呼叫的业务信道。 Of course, a full rate traffic channel means a traffic channel currently supporting a single full rate call, and the half-rate traffic channel means a traffic channel currently supporting one or two half rate calls.

下面结合图4.说明BSC42、基站44和双速率移动台46的较详细的方框图。 Described below in connection with FIG. 4. more detailed block diagram BSC42, the base station 44 and mobile station 46 of the dual rate. 只是为了例示和说明,示出的是功能方框图。 Only for illustration and explanation, it shows a functional block diagram. 然而,那些操作可以用任何适当的电子线路来执行,包括DSP、AGIC、适当编程的主处理机等。 However, those operations may be performed by any suitable electronic circuitry including DSP, AGIC, suitably programmed main processor and the like.

在每个基站的小区、扇区或位置区内的通信业务负荷由BSC42监测。 In the cell of each base station, traffic load, or position of a sector area monitored by BSC42. 然而,这种操作或功能可以由诸如MSC38、每个基站之类的其他实体或者其他无线电网控制实体执行。 However, this operation or function may be made, such as MSC 38, each of the other entities like base stations or other radio network control entity. BSC42包括一个通信业务负荷检测器50,在这个简化的例子中,用来监测由基站44服务的区域X内的通信业务负荷。 BSC42 includes a traffic load detector 50, in this simplified example, to monitor the traffic load in area X by the base station 44. BSC42为每个在它控制下的基站的这种区域执行同样的任务。 BSC42 for each such area the base stations under its control perform the same task. 通信业务负荷检测器50包括一个比较器52和一个全速率业务信道(TCH)占用计数器54。 Traffic load detector 50 includes a comparator 52 and a full-rate traffic channel (TCH) occupies counter 54. 计数器54通过加1和减1来跟踪呼叫区域“X”当前占用的业务信道的总数。 Counter 54 to keep track of the total number of traffic channels currently occupied by the paging area "X" by addition and subtraction 1 1. 一个业务信道如果不能用来支持一个全速率呼叫,就认为是被占用的,也就是说这个信道已部分或者完全分配给了电路交换或分组交换业务。 If a traffic channel can not be used to support a full rate call, it is considered to be occupied, that is to say the channel is assigned to the partially or fully circuit switched or packet switched service. 计数器54的输出与一个门限值(T)一起送至比较器52。 The output of counter 54 with a threshold value (T) to the comparator 52 together. 门限值可以相应于由移动网运营方设置的一定的业务信道数。 The threshold value may correspond to a certain number of traffic channels provided by the mobile network operator. 在计数器的输出超过这个门限时,比较器产生一个通信业务负荷信号,可以用来使控制器56内的一个对于小区X的高负荷标志置位。 The output of the counter exceeds this threshold, the comparator generates a traffic load signal, can be used in the controller 56 so that a high load flag is set for the X cells. 最好,这个门限值(T)具有迟滞(hysteresis),以使不希望有的信道速率切换减到最少。 Preferably, this threshold value (T) having hysteresis (Hysteresis), so that undesired channel rate switching is minimized. 因此,控制器56从各个基站44接收信道请求,向这些基站发布移动通信的信道分配。 Thus, the controller 56 receives the channel request from each base station 44, to release the base stations of the mobile communication channel assignment. 控制器56访问存储器58,存入一个列出当前分配到全速率业务信道的具有双速率能力的移动台的表。 The controller 56 accesses the memory 58, stores a table listing the currently assigned to a full rate traffic channel of the mobile station has the dual rate capability. 在执行信道分配和信道撤消中,控制器56分别递增和递减相应基站区域的全速率TCH占用计数器54。 Performing channel assignment and revocation of the channel, the controller 56 increments and decrements, respectively, the corresponding base station area of ​​the full rate TCH occupied by counter 54.

每个基站44,例如示出的对于小区X的基站,包括许多收发机,用来建立和维护在与区域X内受服务的移动台的无线电接口上的各个信道。 Each base station 44, such as illustrated cell X for a base station, comprising a number of transceivers used to establish and maintain various channels over the radio interface within the area X and services by the mobile station. 一个简化的基站收发机的例子示于方框44,它包括一个基带处理电路60。 Examples of a simplified base station transceiver shown in block 44, which includes a baseband processing circuitry 60. 基带处理电路60通过开关62可切换地连接到全速率编码器/解码器64和半速率编码器/解码器66之一,而全速率编码器/解码器64和半速率编码器/解码器66在相反端通过开关70可切换地连接到收发电路72和天线76。 Baseband processing circuitry 60 switchably connected via switch 62 to the full rate encoder / decoder 64 and a half rate encoder / decoder 66 one, while the full-rate encoder / decoder 64 and a half rate encoder / decoder 66 at the opposite end connected to the transceiver circuit 72 via the switch 70 and the antenna 76 switchably. 基站控制器74执行一系列基站控制操作,包括根据一个特定的通信在一个业务信道上以全速率还是以半速率进行设置开关62和70的位置。 The base station controller controls the base station 74 performs a series of operations, including at half rate or full rate setting switch in a traffic channel in accordance with a particular communication position 62 and 70.

图4中示出的双速率移动台46,除了其他器件,还包括一个基带处理电路80。 FIG 4 shows the dual rate mobile station 46, among other components, further comprises a baseband processing circuitry 80. 基带处理电路80通过开关82可切换地连接到全速率编码器/解码器84和半速率编码器/解码器86之一,而全速率编码器/解码器84和半速率编码器/解码器86的输出端通过开关88可切换地连接到收发电路90和天线94。 Baseband processing circuitry 80 switchably connected to a full-rate encoder / decoder 84 and a half rate encoder / decoder 86 through one switch 82, the full-rate encoder / decoder 84 and a half rate encoder / decoder 86 the output can be switchably connected to the transceiving circuit 90 through the switch 88 and the antenna 94. 双速率移动台控制器92执行一系列控制功能,包括按照移动台接受的是全速率还是半速率信道分配(开始时或切换后)控制开关82和88的位置。 The dual rate mobile station controller 92 performs a series of control functions, including the mobile station is received in accordance with the full rate or half rate channel assignment (or switched after start) position of the control switches 82 and 88.

下面结合图5A所示的流程图说明本发明的第二实施例的工作情况。 Below in connection with FIG. 5A shown in a flowchart illustrating the operation of the second embodiment of the present invention. 当然,基站和基站当前服务的一些移动台是支持和允许改变信道速率的。 Of course, some of the base station and the mobile station currently serving base station is to support and to allow to change the channel rate. 如果不支持或允许改变信道速率,可以阻塞信道速率的改变。 If not allowed to change the channel or the rate to be blocked to change channel rate. 例如,开始分配到一个全速率呼叫的某些呼叫类型,例如数据呼叫之类,在有些情况下,在呼叫开始建立为一个全速率连接后可能不允许改变为半速率呼叫。 For example, some call types is assigned to begin a full-rate call, for example, a data call or the like, in some cases, may not be allowed during call establishment is changed to a half rate call after one full rate connection.

第一个步骤是通信业务负荷检测器利用全速率占用计数器54的输出、门限输入和通信业务负荷检测器50内的比较器52确定通信业务负荷,这在这个第二实施例中相应于当前分配了的全速率业务信道数(方框100)。 The first step is the traffic load detector using the full-rate occupied by the output of the counter 54, and a threshold input traffic load detector comparator 52 determines the traffic load 50, which corresponds to the current distribution in this second embodiment, the number of full rate traffic channels (block 100). 在方框102进行判决,确定当前的通信业务负荷是否超过门限(最好包括一个迟滞值)。 Performed at decision block 102, it is determined whether the current traffic load exceeds a threshold (preferably comprises a hysteresis value). 如果没有,控制返回到方框100,监测通信业务负荷,此时不需要改变信道速率。 If not, control returns to block 100 to monitor the traffic load, the rate at this time does not need to change the channel.

如果这个小区内的通信业务负荷超过门限,BSC控制器56就产生一个在这个小区X内当前分配到全速率业务信道而如果必要的话可以使用半速率业务信道的双速率移动台的表58(方框106)。 If the traffic load in the cell exceeds the threshold, BSC controller 56 generates a current distribution in the cell X to a full rate traffic channel if necessary can use double rate and a half rate traffic channel of the mobile station table 58 (square block 106). 在方框108控制器56做出判决,确定是否有任何双速率移动台包括在这个表内。 Make a decision in block 108 controller 56 determines whether there are any dual rate mobile stations included in this table. 如果没有,控制返回到方框100,重复上述过程。 If not, control returns to block 100 to repeat the above process.

然而,如果有当前分配到一个全速率业务信道的双速率移动台列在表内,就在方框110做出另一个判决,确定区域X的基站配有的任何业务信道是否具有一个空闲的半速率连接。 However, if there are dual rate currently assigned to a full rate traffic channel of the mobile station listed in the list, another decision to be made at block 110 to determine the base station with any area X and some have a traffic channel is idle half rate connections. 如上面结合图3所述,一个业务信道可以支持两个半速率业务信道连接。 As described above in conjunction with FIG. 3, a traffic channel can support two half rate traffic channel connection. 因此,用两个半速率呼叫完全地占用这种业务信道效率较高。 Thus, with two half rate calls occupy completely this higher traffic channel efficiency. 于是将列在这个表的顶上的双速率移动台的当前在全速率业务信道上的呼叫切换到剩余的空闲半速率连接(方框112)。 In the dual-rate would then be the top row of the table is switched to the mobile station currently remaining idle half rate connection (block 112) call a full rate traffic channel. 这个切换为其他呼叫请求释放了一个全速率业务信道,在大业务量需求期间可能有些呼叫请求需要一个全速率业务信道。 Release of a full rate traffic channel for other call this handover request, the call request may be some need for a full rate traffic channels during high traffic demand. 或者,释放的全速率信道可以用来支持两个新的半速率呼叫连接。 Alternatively, the release of full-rate channel can be used to support two new half rate call connection.

BSC控制器56为基站控制器74和移动台控制器92产生必要的切换命令。 The controller 56 is a base station controller BSC 74 and the mobile station controller 92 generates the necessary handover command. 在移动台46起初将一个“信道请求”消息发送给它的服务基站时,基站就用一个“信道需要”消息包括这个信道请求消息,发送给BSC。 When a mobile station 46 will initially "channel request" message to its serving base station, the base station with a "desired channel" message includes the channel request message is sent to the BSC. 信道请求的一个部分表明移动台可以用来通信的信道类别,例如全速率、半速率等等。 A portion of the channel request indicates that the mobile station can be used to the type of communication channel, e.g. full rate, half rate and the like. 然后BSC通过服务基站将一个“信道分配”命令发送给移动台,其中含有一个对需用来建立或切换呼叫的初始或新的半速率业务信道的信道说明。 The BSC then serving base station by a "channel assignment" command to the mobile station, wherein the channel comprises an initial or a new half rate traffic channel is used to establish or switch the call for an explanation. 基站激活这个新的半速率业务信道。 The base station activates the new half rate traffic channel. 对于切换来说,在这个新的业务信道得到确认时,BSC控制器56就通过老的全速率业务信道将一个消息发送给移动台,其中含有有关这个新的半速率业务信道的频率、时隙和输出功率的信息。 For handover, in when the new traffic channel is confirmed, the BSC controller 56 sends a message via the old full rate traffic channel to the mobile station containing a frequency related to the new half rate traffic channel, timeslot information and power output. 移动台调谐到新的频率,在相应时隙上发送切换接入突发脉冲串。 The mobile station tunes to a new frequency, transmits handover access bursts on the appropriate time slot. 一旦检测到和确认了那些突发脉冲串,移动台就发送一个切换完成消息,从而使老的全速率业务信道去活,可以指配给其他通信使用。 Once detected and confirmed those bursts, the mobile station sends a handover complete message, so that the old full rate traffic channel is deactivated, may be assigned to other communications use.

另一方面,如果没有能用另一个空闲的半速率连接支持一个当前半速率连接的业务信道,就在方框114做出判决,确定是否有任何两个半速率信道连接都空闲着的业务信道,也就是一个可以用来支持一个全速率连接或两个半速率连接的业务信道。 On the other hand, if no further use idle half rate traffic channel connection supporting a current half rate connection, it is made in decision block 114, it is determined whether any two half rate channels are connected to the idle traffic channel , i.e. be a support for a full rate connection or two half rate traffic channel connection. 如果没有,就清除双速率移动台表58(方框122),过程返回方框100。 If not, remove the dual rate mobile station table 58 (block 122), the process returns to block 100. 相反,如果有一个可用的半速率信道连接,就对列在表58的顶上的移动台执行切换,从一个当前的全速率连接切换到一个在方框114确定的空闲业务信道上的新的半速率连接(方框116)。 Conversely, if there is an available half rate channel connection, executed in the switching table 58 atop the mobile station columns, switching from a current full rate connection to the idle traffic channel at a block 114 determines new half rate connection (block 116). 在方框112或116执行切换时,删除列在表58的顶上的移动台表项(方框118)。 When block 112 or 116 performs handover deleting columns 58 on top of the table entries of the mobile station (block 118). 然后在方框120做出判决,确定通信业务负荷是否小于门限一个迟滞量。 Is then made at decision block 120, it is determined whether the traffic load is less than a threshold hysteresis. 如果不是,小区仍处于大业务量情况下,可以通过将信道速率从全速率改变为半速率连接增添附加容量。 Under high traffic, the half rate connection may add additional capacity by changing the channel rate from full rate, if not, is still in the cell. 相反,如果通信业务负荷已经充分降低到门限以下,就在方框122清除表58,过程返回方框100。 Conversely, if the traffic load has been sufficiently reduced to below the threshold, block 100 returns to block 122 to clear the table 58, process.

如果在判决方框102确定通信业务负荷超过门限,BSC控制器56就试图通过为新的呼叫请求分配容许/可能的半速率业务信道以提高容量,见图5A中的标志A,下面将结合图5B所示流程图进行说明。 In decision block 102 determines if the traffic load exceeds the threshold, the BSC controller 56 will attempt to allocate a new call request permissible / possible half rate traffic channels to increase capacity, the flag shown in Figure 5A A, below in connection with FIG. the flowchart shown in 5B. 在大业务量负荷情况下,每接收到一个新的信道请求(方框130),就根据在这个信道请求消息中含有的与这个信道请求关联的移动台能够处理什么类型的信道的指示确定移动台的速率能力(方框132)。 In high traffic load condition, each receives a new channel request (block 130), it is possible to handle any type of channel based on the channel request from the mobile station to the channel associated with the request message contained indicating the determined movement stage rate capability (block 132). 如果需要一个全速率业务信道(无论是什么原因),就继续信道建立,分配一个全速率业务信道,假如有一个全速率业务信道可用的话。 If you need a full-rate traffic channel (for whatever reason), the channel will continue to build, assign a full-rate traffic channel, if there is a full-rate traffic channel is available. 然而,如果对于这个当前的呼叫请求不需要一个全速率业务信道,就分配一个半速率业务信道(方框136),然后控制返回到图5中的方框100。 However, if the request for the current call does not require a full rate traffic channel, allocates a half-rate traffic channels (block 136), then control returns to block 100 in FIG. 5. 在检测到通信业务负荷已经充分降低时,可以执行一个任选的过程,将一些正在进行的半速率呼叫有选择地切换到可用的全速率信道上。 Upon detecting the traffic load has been sufficiently reduced, an optional process may be performed, some of the ongoing half rate calls to selectively switch the available full rate channels.

考虑以下这个简单的例子。 Consider the following simple example. 假定基站44具有总共四个收发机,每个收发机包括八个时隙信道。 Assumed that the base station 44 has a total of four transceivers, each transceiver includes eight time slot channels. 因此,这个基站包括总共三十二个时隙,其中有三个用于控制信道信令,而留下的二十九个时隙用于业务信道。 Thus, the base station includes a total thirty-two slots, three of which for control channel signaling, leaving the twenty-nine time slots for traffic channels. 再假设所有的基站收发机都能够传送全速率和半速率信道。 Suppose that all the base station transceiver can transmit full rate and half rate channels. 假设有一半的移动台能够进行双速率通信,而另一半只能进行全速率通信。 Suppose half of dual rate mobile station can communicate, and the other half only full rate communication. 通信业务负荷门限设置为百分之七十五,迟滞为百分之五。 Traffic load threshold is set to 75 per cent to five per cent hysteresis. 对于这例子来说转换成业务信道数,就是门限为二十二个业务信道,迟滞为一个业务信道。 For example, it is converted into a number of traffic channels, that threshold is twenty-two traffic channel, hysteresis is a traffic channel. 因此,高负荷标志在当前占用的业务信道达到二十三个或更多个时置位,而在当前占用的业务信道少于二十一个时复位。 Thus, a high load flag in the traffic channel currently occupied by three or more reaches20 When set, and less than twenty reset when a traffic channel currently occupied.

假定这些业务信道当前是这样使用的:二个业务信道作为分组数据信道分配,十个业务信道由只能够全速率的移动台占用,一个业务信道由二个半速率呼叫占用,二个业务信道每个各由一个半速率呼叫占用,七个业务信道由当前正采用全速率连接的双速率移动台占用。 It assumed that the traffic channels are currently used in this way: two traffic channels as a packet data channel allocation, ten traffic channel consists of only movable stations occupies the full rate, a traffic channel calls is occupied by two half rate, two traffic channels per each call occupies one of a half rate, seven traffic channels are currently being employed by the dual rate mobile station full occupancy rate of the connection. 加起来,总共有二十二个业务信道被占用,因此大业务量负荷标志不置位。 Add up to a total of twenty-two traffic channel is occupied, so high traffic load flag is not set.

假设,又为另一个双速率移动台建立一个全速率呼叫。 It is assumed, and the mobile station establishes a call to another full rate double the rate. 于是大业务量负荷标志置位。 Thus high traffic load flag is set. 基站控制器56产生一个列有切换候选对象的双速率移动台表。 The base station controller 56 generates handover candidate lists a dual rate mobile station table. 这个表包括八个表项,与当前正在使用全速率连接的八个双速率移动台相应。 This table includes eight table entries, and are in full rate eight dual rate mobile stations corresponding connector. 这些全速率连接每次一个地切换成半速率信道,直到高负荷状况缓解。 These full rate connections each switched to a half rate channel until the high load condition ease. 例如,将第一个全速率连接移到一个部分已经分配给传送一个半速率呼叫连接的业务信道中的业务信道上的一个空闲的半速率连接。 For example, the first full rate connection is moved to a transfer portion has been assigned a half-rate call a half rate traffic channel idle traffic channel connection. 在这个第一切换后,占用的业务信道数等于二十二,假如没有建立新的呼叫,那这个数并没有低到足以使高负荷标志复位。 After this first handover, the number of traffic channels occupied by equal XXII, if not establish a new call, and that this number is not low enough to reset the high load flag. 于是,将第二个连接移到第二个部分已分配的业务信道的空闲部分。 Thus, the second connection is moved to the idle part of the second portion of the allocated traffic channel. 占用的业务信道数降低为二十一,这同样没有低到足以使高负荷标志复位。 The number of traffic channels occupied by the twenty-first reduced, which also is not low enough to reset the high load flag. 将第三个全速率连接移到一个空闲的全速率信道上的一个半速率信道。 The third full rate connection is moved to an idle full rate channel and a half rate channel. 再将第四个连接移到这个业务信道上的另一个可用的半速率连接。 Then another fourth connection over this traffic channel available half rate connection.

通过将这四个全速率连接转换到四个新的半速率连接,占用的业务信道数从二十三减少到二十。 These four connection by converting full rate to half rate four new connection, the number of traffic channel occupancy from twenty-three reduced to twenty. 结果,就以成本比较来说最低的执行区内切换腾出了四个附加业务信道,可以用来为其他呼叫服务。 As a result, it is relatively low cost of implementation of district switched to free up four additional traffic channels can be used for other call services. 从而用动态方式有效地满足了业务需求浪涌,而不需要补充基站收发机。 Dynamic manner thereby effectively meet business needs surge without the need to add a base transceiver station.
