Description

专线用户的实现方法 技术领域 本发明涉及移动通信***中的增强型码分多址高速分组数据技术 FIELD OF THE INVENTION The present invention relates to enhanced code division multiple access high speed packet data technology in a mobile communication system
( CDMA IX EV-DO, EDMA IX Evolution Date Only )， 尤其涉及一种基 于 CDMA IX EV-DO的网络***专线用户的实现方法。 (CDMA IX EV-DO, EDMA IX Evolution Date Only), especially relates to a method for implementing a dedicated subscriber of a network system based on CDMA IX EV-DO.
背景技术 Background technique
在移动通信***中， 对于希望获得更加快速或者更大容量数据处理服 务的用户而言， CDMA 2000技术的优化版本 CDMA IX EV-DO技术在数 据处理方面可以支持的最高传输速率能够超过 2Mbps， 其吞吐量能够超过 700kbps,因此这种数据传输速率将能够与有线数字用户环路（ DSL， Digital Subscriber Line )的数据传输速率相比； 与此同时， CDMA IX EV-DO技术 还可以支持对数据传输速度要求更加严格的服务， 如视频传输、 大型文件 下载等服务。 CDMA2000 IX EV-DO技术还能够以每兆字节最低成本来传 输数据， 这点将是促进无线互联网大量普及的一个重要因素。  In mobile communication systems, the optimized version of CDMA 2000 technology, CDMA IX EV-DO technology, can support data transmissions with a maximum transmission rate of more than 2 Mbps for users who wish to obtain faster or larger capacity data processing services. The throughput can exceed 700kbps, so this data transmission rate will be comparable to the data transmission rate of the Cable Digital Subscriber Line (DSL); at the same time, CDMA IX EV-DO technology can also support data transmission. Services that require more stringent speeds, such as video transmission, large file downloads, and more. CDMA2000 IX EV-DO technology can also transmit data at the lowest cost per megabyte, which will be an important factor in promoting the popularity of wireless Internet.
目前， 在 CDMA IX EV-DO网络***中， 用户终端和***之间建立呼 叫连接后， 由***根据各个用户终端上报的信号强度中最大的信号强度来 决定前向数据发送速率， 为了达到前向发送带宽吞吐量的最大化， 一般信 号强度较高的用户往往会得到较高的发送速率（即占用较宽的前向发送带 宽)， 信号强度较低的用户往往会得到较低的发送速率 （即占用较窄的前 向发送带宽）。  At present, in a CDMA IX EV-DO network system, after a call connection is established between a user terminal and a system, the system determines the forward data transmission rate according to the maximum signal strength of the signal strength reported by each user terminal, in order to achieve the forward direction. The maximum transmission bandwidth is maximized. Generally, users with higher signal strength tend to get higher transmission rates (that is, occupy a wider forward transmission bandwidth), and users with lower signal strength tend to get lower transmission rates ( That is, occupying a narrow forward transmission bandwidth).
在由用户终端至***的反向数据传输过程中 , 各个用户终端会根据系 统前向发送的反向激活位（RAB， Reverse Activity Bit )指示， 并依据*** 前向下发的转移概率表来上调或降低自身的反向数据发送速率。  In the reverse data transmission process from the user terminal to the system, each user terminal is instructed according to the reverse activity bit (RAB, Reverse Activity Bit) sent by the system forward, and is adjusted according to the transition probability table issued before the system. Or reduce its own reverse data transmission rate.
请参阅图 1 , 该图是目前在 CDMA IX EV-DO网络***中， 用户终端 上调或降低自身发送功率的过程示意图； 即：  Please refer to FIG. 1 , which is a schematic diagram of a process for a user terminal to increase or decrease its own transmit power in a CDMA IX EV-DO network system;
用户终端基于激活扇区 向广播的 RAB指示会自动进行反向发送速 率的调整；  The user terminal automatically adjusts the reverse transmission rate based on the active sector to the broadcast RAB indication;
一般情况下， ***在自身承载负荷较重时，将前向发送 RAB置位为 1 的指示信息； 在自身承载负荷较轻时， 将前向发送 RAB置位为 0的指示 息 In general, the system sets the forward transmit RAB to 1 when its own load is heavy. Indication information; when the bearer load is light, the forward transmission RAB is set to 0.
其中用户终端在 RAB=1时， 将以概率 q降低发送速率（其概率 q由 基站设定或由终端采用缺省值， 如图 1 中用户终端可以由发送速率 153.6Kbps 降低到发送速率 153.6Kbps x q4 = 76.8Kbps ); 如果用户终端的 反向发送速率已经低于 9.6Kbps， 将不再降低； When the user terminal is at RAB=1, the transmission rate will be reduced by the probability q (the probability q is set by the base station or the default value is adopted by the terminal. In FIG. 1, the user terminal can be reduced from the transmission rate of 153.6 Kbps to the transmission rate of 153.6 Kbps. Xq 4 = 76.8Kbps ); If the reverse transmission rate of the user terminal is already lower than 9.6Kbps, it will not be reduced;
用户终端在 RAB=0时， 将以概率 p上调发送速率 （其概率 p由基站 设定或由终端采用缺省值， 如图 1中用户终端可以由发送速率 9.6Kbps上 调到发送速率 9.6Kbps X pi = 19.2Kbps ); 如果用户终端的反向发送速率已 经高于最大限制速率 153.6Kbps， 将不再上调； 同时， 如果用户终端的反 向发射功率不足， 也将不再上调。  When RAB=0, the user terminal will increase the transmission rate with probability p (the probability p is set by the base station or the default value is adopted by the terminal. In Figure 1, the user terminal can be adjusted from the transmission rate of 9.6 Kbps to the transmission rate of 9.6 Kbps. Pi = 19.2Kbps); If the reverse transmission rate of the user terminal is already higher than the maximum limit rate of 153.6Kbps, it will not be up-regulated; meanwhile, if the reverse transmission power of the user terminal is insufficient, it will not be adjusted any more.
综上， 目前在 CDMA IX EV-DO网络***中， 用户终端和***之间建 立呼叫连接后， 由***根据各个用户终端上报的信号强度中最大的信号强 度来决定前向数据的发送速率， 同时为了达到前向发送带宽吞吐量的最大 化， 可以根据用户终端反向发送的反向激活（ RA， Reverse Activity )指示， 在***承载负荷和与用户终端之间的数据传输速率之间达到一个均衡。 但 是这种数据速率传输方式会造成信道条件相对不好的用户终端（即相对于 其他用户终端而言， 信号强度较低的用户）的数据传输速率很低， 严重时 甚至会掉线， 这样就无法实现对单个用户提供可保证的数据传输速率， 也 就无法满足用户对部分服务的需求， 如某些申请了 艮行业务的用户希望能 够采用有保证的专线速率来用于数据交换， 完成 ATM取款等操作。  In summary, in the CDMA IX EV-DO network system, after the call connection is established between the user terminal and the system, the system determines the transmission rate of the forward data according to the maximum signal strength of the signal strength reported by each user terminal, and simultaneously In order to maximize the throughput of the forward transmission bandwidth, an equalization between the system bearer load and the data transmission rate between the user terminal and the user terminal can be achieved according to the reverse activity (RA, Reverse Activity) indication sent by the user terminal in reverse. . However, this data rate transmission method causes a user terminal with relatively poor channel conditions (that is, a user with a lower signal strength than other user terminals) to have a low data transmission rate, and even drops the line when it is severe, so that It is impossible to provide a guaranteed data transmission rate for a single user, and thus cannot meet the user's demand for some services. For example, some users who apply for banking services want to use a guaranteed leased line rate for data exchange, complete ATM. Withdrawal and other operations.

具体实施方式 本发明提出的专线用户的实现方法要首先能够对某些用户提供可保 证的专线速率， 然后再根据其他非专线用户终端上报的信号强度来决定对 非专线用户的前向发送速率， 使得前向发送带宽的吞吐量尽可能到达最大 化； 同时还要根据专线用户申请的反向专线速率， 通过***指示的转移概 率表， 上调自身的反向发送速率到其申请的反向专线速率， 并对其他非专 线用户下发 RAB指示， 来使非专线用户上调或降低自身的反向发送速率， 从而实现在***承载负荷和与用户终端的数据传输速率之间达到一个均 衡。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The implementation method of the private line user proposed by the present invention can firstly provide a guaranteed dedicated line rate for some users, and then determine the forward transmission rate of the non-dedicated line user according to the signal strength reported by other non-dedicated user terminals. The throughput of the forward transmission bandwidth is maximized as much as possible; at the same time, according to the reverse dedicated line rate applied by the dedicated line user, the reverse transmission rate of the system is adjusted to the reverse dedicated line rate of the application through the transition probability table indicated by the system. The RAB indication is sent to other non-dedicated users to increase or decrease the reverse transmission rate of the non-dedicated subscribers, thereby achieving an equilibrium between the system bearer load and the data transmission rate of the user terminal.
下面结合各个附图， 对本发明专线用户的实现方法的具体实施方式进 行详细的阐述。 请参阅图 2， 该图是本发明专线用户的实现方法实施例流 程图， 按照图 2: The specific implementation manners of the implementation method of the private line user of the present invention will be described in detail below with reference to the accompanying drawings. Please refer to FIG. 2, which is a flow of an implementation method of a dedicated line user of the present invention. Chengtu, according to Figure 2:
步骤 S10, 设置专线用户所需的前向专线速率； 这主要是根据用户实 际需要享受何种数据通信业务， 来设置相应的前向专线速率；  Step S10, setting a forward dedicated line rate required by the dedicated line user; this is mainly to set a corresponding forward dedicated line rate according to what data communication service the user actually needs to enjoy;
步骤 S20, 用测试的方式（实际中采用电测试的方式）获得专线用户 所处位置的数据速率控制（DRC )值； 电测试， 即模拟用户在相应位置的 使用情况， 来测得用户在该位置接收前向信号的强度值；  Step S20, obtaining a data rate control (DRC) value of a location where the dedicated line user is located by using a test method (in practice, using an electrical test method); and electrically testing, that is, simulating a user's use at the corresponding location, to measure that the user is in the The position receives the intensity value of the forward signal;
步骤 S30 , 用步骤 S10中用户申请的前向专线速率除以步骤 S20中测 得的专线用户所处位置的 DRC值， 从而得到满足该用户前向专线速率的 前向发送时隙与前向发送总时隙的比值；  Step S30, dividing the forward dedicated line rate applied by the user in step S10 by the DRC value of the location of the dedicated line user measured in step S20, thereby obtaining a forward transmission time slot and forward transmission that meet the forward dedicated line rate of the user. Ratio of total time slots;
如上， 由于在 CDMA IX EV-DO移动通信***中， ***前向采用时分 多址结构， 用户的优先级和业务的优先级最终体现在用户对资源的占用比 例上， 也就是对时隙资源的占用比例上。 因此， 在 CDMA 1X EV-DO移动 通信***中， 专线用户如果希望得到签约的专线速率， 在自身所处位置特 定的 DRC情况下， 必须占用前向发送总时隙中的足够时隙数， 才能保证 得到签约的前向专线速率。  As above, since in the CDMA IX EV-DO mobile communication system, the system adopts a time division multiple access structure in the forward direction, the priority of the user and the priority of the service are finally reflected in the proportion of the user occupied by the resources, that is, the time slot resources. Occupancy ratio. Therefore, in the CDMA 1X EV-DO mobile communication system, if the leased line user wants to obtain the leased line rate, it must occupy a sufficient number of slots in the forward transmission total time slot in the case of a specific DRC in its own location. Guarantee the rate of the forward line of the contract.
其中这里所提及的专线用户可以为 CDMA IX EV-DO移动通信*** 中的固定用户 （指位置相对固定的移动台用户）或移动用户 （指可以随意 移动的移动台用户）。 其中对于某些固定用户而言， 其 DRC值是相对固定 的， 所以如果在专线用户开户之前， 对专线用户所处位置进行电测， 就可 以预测满足该用户专线速率时对前向发送资源的占用 （即需要的前向发送 时隙数）。  The dedicated line users mentioned here may be fixed users (referring to mobile station users with relatively fixed positions) or mobile users (referring to mobile station users who can move freely) in the CDMA IX EV-DO mobile communication system. For some fixed users, the DRC value is relatively fixed. Therefore, if the location of the dedicated line user is electrically measured before the dedicated line user opens an account, it can be predicted that the forward transmission resource is satisfied when the subscriber line rate is met. Occupied (ie the number of forward transmit slots required).
请参阅图 3, 该图是在本发明专线用户的实现方法中， 用户要享用专 线速率时所要占用的前向发送时隙示意图； 理论研究表明： 每个专线用户 对前向资源的占用比例（即对前向发送总时隙的占用比例）等于专线用户 的专线速率除以用户所处位置的 DRC值；  Please refer to FIG. 3 , which is a schematic diagram of a forward transmission time slot occupied by a user when enjoying a dedicated line rate in the implementation method of the private line user of the present invention; theoretical research shows: the proportion of each dedicated line user to the forward resource ( That is, the proportion of the total time slot for the forward transmission is equal to the line rate of the dedicated line user divided by the DRC value of the location where the user is located;
假设图 3中 （a ): 专线用户所处位置的 DRC=153.6Kbps， 专线用户申 请的实际专线速率 =38.4Kbps , 则该专线用户享用其签约的专线速率时， 占用前向发送时隙的数目和前向发送总时隙的数目之间的比例 =38.4/153.6=1/4; 如图中每 4个时隙中就要有一个时隙专门用来为该专线 用户前向发送数据； Assume that (a) in Figure 3: DRC=153.6Kbps where the dedicated line user is located, and the actual dedicated line rate applied by the leased line user=38.4Kbps, the number of forward transmission slots occupied by the dedicated line user when enjoying the leased line rate The ratio between the total number of forward transmission slots and the number of forward transmission slots = 38.4/153.6 = 1/4; one of every four time slots in the figure is dedicated to the dedicated line. The user sends data forward;
4『ϋ殳图 3中（b ): 专线用户所处位置的 DRC=153.6Kbps， 专线用户申 请的实际专线速率 =76.8Kbps , 则该专线用户享用其签约的专线速率时， 占用前向发送时隙的数目和前向发送总时隙的数目之间的比例 =76.8/153.6=1/2; 如图中每 4个时隙中就要有 2个时隙专门用来为该专线 用户前向发送数据；  4 ϋ殳 Figure 3 (b): The DRC of the dedicated line user is 153.6Kbps, and the actual line rate applied by the leased line user = 76.8Kbps, when the leased line user enjoys the leased line rate, when the forward transmission is occupied The ratio between the number of slots and the number of forward transmission total time slots = 76.8 / 153.6 = 1/2; in the figure, there are 2 time slots in every 4 time slots dedicated to the forward direction of the dedicated line user. send data;
假设图 3中 （c ): 专线用户所处位置的 DRC=153.6Kbps， 专线用户申 请的实际专线速率 =115.2Kbps， 则该专线用户享用其签约的专线速率时， 占用前向发送时隙的数目和前向发送总时隙的数目之间的比例 =115.2/153.6=3/4;如图中每 4个时隙中就要有 3个时隙专门用来为该专线 用户前向发送数据；  Assume that (c) in Figure 3: DRC=153.6Kbps where the dedicated line user is located, and the actual dedicated line rate applied by the leased line user=115.2Kbps, the number of forward transmission slots occupied by the dedicated line user when enjoying the leased line rate The ratio between the total number of forward transmission slots and the number of forward transmission slots = 115.2/153.6=3/4; as shown in the figure, there are 3 slots in each of the 4 slots to transmit data forward for the dedicated line subscriber;
假设图 3中（d ): 专线用户所处位置的 DRC=153.6Kbps, 专线用户申 请的实际专线速率 =153.6Kbps， 则该专线用户享用其签约的专线速率时， 占用前向发送时隙的数目和前向发送总时隙的数目之间的比例 =153.6/153.6=1 ; 如图中所有的时隙都将专门用来为该专线用户前向发送 数据。  Assume that (d) in Figure 3: DRC=153.6Kbps where the leased line user is located, and the actual leased line rate applied by the leased line user=153.6Kbps, the number of forward transmit slots occupied by the leased line user when enjoying the leased line rate The ratio between the total number of forward transmission slots and the number of forward transmission slots = 153.6/153.6 = 1; all time slots in the figure will be used exclusively for the dedicated line user to forward data.
步骤 S40， ***根据步骤 S30中所求取的比值， 利用前向发送总时隙 中的相应时隙为专线用户提供其申请的前向专线速率， 如上所述， 如果才艮 据用户申请的专线速率和用户所处位置的 DRC求得所述比值为 1/2，则系 统会将前向发送总时隙中的一半时隙用来为该专线用户前向发送数据， 达 到其申请的前向专线速率。  Step S40: The system provides the forward line rate of the application for the dedicated line user by using the corresponding time slot in the forward transmission total time slot according to the ratio determined in step S30, as described above, if the user applies for the dedicated line The rate and the DRC of the location of the user find that the ratio is 1/2, and the system uses half of the forward transmission total time slots to forward the data for the dedicated line user to reach the forward direction of the application. Dedicated line rate.
其中***在为专线用户提供前向专线速率时， 还要考虑如下过程： 根据上述步骤 S30所求取的比值， 计算为满足所有专线用户前向专线 速率将限制非专线用户接入的数目；  When the system provides the forward line rate for the dedicated line user, the following process is also considered: According to the ratio obtained in the above step S30, it is calculated that the forward dedicated line rate of all the dedicated line users will limit the number of access by the non-dedicated line users;
然后根据上述所求得的非专线用户接入数目， ***通过限制所述数目 的非专线用户接入， 来达到为所有专线用户提供其申请的前向专线速率的 目的。  Then, according to the number of non-dedicated user accesses obtained as described above, the system achieves the purpose of providing the forward line rate of the application for all the dedicated users by limiting the number of non-dedicated users.
由于本发明专线用户的实现方法需要在原有***资源准入控制的基 础上， 来保证专线用户的随时接入， 并且要求在专线用户接入后能够确保 该用户能得到自身申请的前向专线速率， 因此就需要根据专线用户对*** 前向发送资源的占用情况来对***准许接入的普通用户数目进行限制， 以 保证***的承载负载能够处于合理状态。 The implementation method of the dedicated line user of the present invention needs to be based on the original system resource access control to ensure the access of the dedicated line user at any time, and is required to be ensured after the dedicated line user accesses. The user can obtain the forward dedicated line rate of the application. Therefore, it is necessary to limit the number of ordinary users allowed to access the system according to the occupation of the forwarded resources of the system by the dedicated line user, so as to ensure that the load of the system can be in a reasonable state. .
因为考虑到专线用户对***前向资源的占用， 可以通过电测专线用户 所处位置的无线环境来求得相应的 DRC值， 并结合专线用户实际申请的 专线速率来计算专线用户要享用其申请的专线速率， 实际要占用前向发送 资源的比例情况， 然后才艮据所求取的比例来决定该专线用户能否得到其申 请的实际专线速率。 在***可以满足专线用户实际专线速率需求的情况 下， 则还要计算一个专线用户的加入所带来的前向资源占用将限制多少其 他非专线用户 （即普通用户）的加入， 即一个专线用户对前向发送时隙的 占用将相当于几个非专线用户对前向发送时隙的占用； 例如： 在一个小区 内， 一般会有 30个用户同时使用***的前向发送资源， 如果在该小区内， 一个专线用户享用其申请的前向专线速率， 将占用前向发送资源的 1/2， 则剩余前向发送资源能够支持非专线用户接入的数目就是 30 χ ( 1 - 0.5 ) = 15个， 即该专线用户的加入会限制 15个普通用户的加入。  Because the private line user's occupation of the system's forward resources is taken into consideration, the corresponding DRC value can be obtained by the wireless environment where the electric line user is located, and the line user actually applies for the line rate to calculate the line user to enjoy the application. The rate of the dedicated line, which actually occupies the proportion of forward-sending resources, and then decides whether the line user can get the actual line rate of the application according to the ratio. In the case that the system can meet the actual line rate requirements of the dedicated line users, it is also calculated that the forward resource occupancy caused by the joining of a dedicated line user will limit the number of other non-dedicated users (ie, ordinary users) to join, that is, a dedicated line user. The occupation of the forward transmission time slot will be equivalent to the occupation of the forward transmission time slot by several non-dedicated lines; for example: in a cell, generally 30 users use the forward transmission resources of the system at the same time, if In the small area, the rate of the forward line of a dedicated line user enjoying the application will occupy 1/2 of the forward transmission resource, and the number of remaining forward transmission resources capable of supporting non-dedicated line access is 30 χ ( 1 - 0.5 ) = 15, that is, the joining of the dedicated line user will limit the participation of 15 ordinary users.
由于对于专线用户而言， 如果该类用户的信道条件较差， 将会占用较 多甚至是***难以承受的前向发送资源 , 因此对该类用户的支持应当限于 该用户在一段时间内所处位置相对比较稳定， 即在专线用户开户前需要对 其进行电测， 确保用户所处位置的 DRC满足开户需求时才能给予开户， 即***要根据上述所求得的专线用户要达到其前向专线速率， 要占用的前 向发送时隙和前向发送总时隙之间的比值， 来判断是否能够为该专线用户 提供前向专线速率服务。 所谓确保用户所处位置的 DRC满足开户需求是 指用户所处位置的 DRC值应该是该专线用户所要申请的前向专线速率的 N倍以上（N>=1 )， 电测时要求对用户的最高前向发送速率能够达到其所 要申请的前向专线速率要求， 这样根据前述专线用户占用前向发送资源的 比例是其申请的前向专线速率除以用户所处位置的 DRC值， 才可以保证 专线用户占用前向发送资源的比例不会超过 1 , 以保证整个***前向发送 资源不致过渡耗尽到一个专线用户上， 保证其他用户的接入。  Because for the dedicated line users, if the channel conditions of such users are poor, it will occupy more forward transmission resources that are unbearable to the system. Therefore, support for such users should be limited to the user's time in a period of time. The location is relatively stable, that is, the dedicated line user needs to be electrically tested before opening an account, to ensure that the DRC of the user's location can meet the account opening requirements, that is, the system must reach the forward line according to the above-mentioned line-specific users. Rate, the ratio between the forward transmit time slot and the forward transmit total time slot to be used to determine whether the forward line rate service can be provided for the dedicated line user. The so-called DRC that ensures the location of the user meets the account opening requirement means that the DRC value of the location where the user is located should be more than N times the rate of the forward dedicated line to be applied by the dedicated line user (N>=1), and the user is required for the electrical measurement. The highest forward transmission rate can reach the forward private line rate requirement of the application, so that the ratio of the forward dedicated line rate of the application to the forward line user is the DRC value of the user's location. The proportion of leased resources that the leased line users use will not exceed one, so as to ensure that the forward transmission resources of the entire system will not be exhausted to a dedicated line user, and other users' access is guaranteed.
同时， 专线用户可能会因为在长期应用中无线环境的变化， 导致其前 向专线速率无法达到预期的效果， 这时就需要进行天线的调整， 当***无 法满足专线用户的专线速率时可以停止为其服务， 在能够提供的情况下再 继续为其提供专线速率服务。 要求***侧的基站能够通过空中接口资源优先调度专线用户， 其中确保专 线用户能够优先被调度到， 可以通过为专线用户所处位置的 DRC值乘以 一权重值来实现。 因为在基站对专线用户的调度过程中， 对专线用户所处 位置的 DRC值乘以一权重值 N，等同于使专线用户所处位置的 DRC值升 高了 N倍， 这样就可以保证专线用户能够优先被基站调度到。 同理， 如果 为专线用户所处位置的 DRC乘以足够大的权重值， 则可以保证专线用户 总能被基站调度到。 当然， 也可以通过其他调度策略来确保专线用户能够 被基站通过空中接口资源优先调度到， 这里不再赘述。 At the same time, dedicated subscribers may be due to changes in the wireless environment during long-term applications. The rate to the leased line cannot achieve the expected effect. In this case, the antenna needs to be adjusted. When the system cannot meet the leased line rate of the leased line user, it can stop serving it and continue to provide the line rate service if it can provide. The base station on the system side is required to preferentially schedule the dedicated line user through the air interface resource, wherein the dedicated line user can be preferentially scheduled, and can be implemented by multiplying the DRC value of the location where the dedicated line user is located by a weight value. Because in the scheduling process of the base station to the private line user, multiplying the DRC value of the location of the dedicated line user by a weight value N is equivalent to increasing the DRC value of the location of the dedicated line user by N times, thereby ensuring the dedicated line user. It can be preferentially scheduled by the base station. Similarly, if the DRC of the location where the leased line user is located is multiplied by a sufficiently large weight value, it can be guaranteed that the leased line user can always be scheduled by the base station. Of course, other scheduling policies can also be used to ensure that the dedicated line users can be preferentially scheduled by the base station through the air interface resources, and details are not described herein again.
同时， 为避免专线用户的前向发送速率超过其申请的专线速率， *** 可以通过对专线用户的前向发送速率进行速率限制来实现， 即可以通过网 络侧 （如无线接入网、 核心网或者 IP 网络等）对专线用户的前向发送速 率进行限速控制， 以确保对专线用户的前向发送速率不会超过其申请的前 向专线速率， 避免专线用户过渡占用***的前向发送资源。  At the same time, in order to prevent the forward transmission rate of the private line user from exceeding the rate of the dedicated line, the system can implement the rate limiting of the forward transmission rate of the private line user, that is, through the network side (such as the wireless access network, the core network, or IP network, etc.) The rate limit of the forward transmission rate of the leased line user is controlled to ensure that the forward transmission rate of the leased line user does not exceed the forward line rate of the application, and the private line user is prevented from using the forward transmission resource of the system.
为满足某些数据业务的要求， 在设置了专线用户所需的前向专线速率 的同时， 还要设置用户所需的反向专线速率； 以使专线用户可以根据*** 设置的反向转移概率表， 上调自身的反向发送速率， 并在上调到设置的反 向专线速率时， 保持在该反向专线速率上。 其中为实现专线用户在上调自 身的反向发送速率到其申请的反向专线速率时保持在该反向专线速率上 的方式可以通过***设置反向转移概率表中到达该专线用户所需的反向 专线速率后的上调概率为零来实现； 也可以通过***在检测到专线用户的 反向发送速率到达设置的该反向专线速率时， 向专线用户发送速率限制信 令（ Rate_Limit信令）来实现， 从而来限制专线用户的反向发送速率不会 超过其申请的反向专线速率， 以避免过渡占用***资源。  In order to meet the requirements of some data services, the forward line rate required by the line user is set, and the reverse line rate required by the user is also set; so that the line user can set the reverse transfer probability table according to the system setting. , up-regulates its own reverse send rate and remains at the reverse line rate when it is raised to the set reverse line rate. The way in which the private line user maintains the reverse dedicated line rate when the reverse transmission rate of the private line is raised to the reverse line rate of the application can be set by the system to set the reverse transfer probability table to reach the required line of the dedicated line user. The probability of the uplink to the dedicated line rate is zero; or the system may send the rate limiting signaling ( Rate_Limit signaling) to the dedicated line when the reverse transmission rate of the dedicated line user is detected to reach the set reverse line rate. This is implemented to limit the reverse rate of the private line user's reverse transmission rate beyond the reverse line rate of the application, to avoid the transition to occupy system resources.
其中， 反向发送资源的管理是通过控制用户终端的发射功率来保证专 线用户在一定的反向专线速率下， 其发送的信息总能够被正确解调的。 从 实际应用来看， 这种功控效果是基本令人满意的， 即通过功控方式可以保 证不管专线用户距离基站的距离是多远（正常覆盖下）， 相同反向发送速 率的用户对基站的干扰基本上是相同的（功控过程中可能会有波动， 此处 可以忽略不计）； 专线用户对其他用户的干扰及对基站反向承载负荷的贡 献也只和专线用户的反向发送速率及当前***总的承载负荷有关。 The management of the reverse transmission resource is to ensure that the dedicated line user can be correctly demodulated at a certain reverse dedicated line rate by controlling the transmission power of the user terminal. From In practical application, this kind of power control effect is basically satisfactory, that is, the power control mode can ensure that no matter how far the dedicated line user is from the base station (normal coverage), the user with the same reverse transmission rate to the base station The interference is basically the same (there may be fluctuations in the power control process, which can be ignored here); the interference of the private line user to other users and the contribution to the reverse bearer load of the base station is only the reverse transmission rate of the dedicated line user and The current total load carrying capacity of the system is related.
以上所述仅是本发明的优选实施方式， 应当指出， 对于本技术领域的 普通技术人员来说， 在不脱离本发明原理的前提下， 还可以做出若干改进 和润饰， 这些改进和润饰也应视为本发明的保护范围。  The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It should be considered as the scope of protection of the present invention.
