Description

一种应用于GSM基站的节能方法 The method of one kind of energy is applied to the GSM base station

技术领域 FIELD

本发明涉及到移动通信系统中基站的节能方法,尤其涉及到有多个处理单元的容量较大的中心基站,在现有的业务处理流程中添加了新的模块,形成一个新的节能子系统,使基站能够根据业务负荷自动及时调整参与运行的处理单元数量,从而达到节省能源的目的。 The present invention relates to a power saving method in a mobile communication system, a base station, and more particularly to a plurality of processing units of larger capacity central base station, a new module is added in the existing business processes, forming a new energy subsystem , so the base station can be automatically adjusted in time involved in the processing unit operates according to the number of traffic load, so as to achieve energy saving.

背景技术 Background technique

GSM系统的设备可以分为交换分系统SSS,亦称为网络分系统,基站分系统BSS,移动站及操作维护分系统OSS四大分系统设备。 Device GSM system can be divided into the exchange subsystem SSS, also known as a network subsystem, the BSS base station subsystem, the mobile station and the operation and maintenance subsystem OSS four subsystems equipment. 在移动通信运营商的运营成本中,基站分系统所消耗的电力占到很大一部分,如果能够有效减少这部分开支,则会大幅度节省运营成本并达到节省能源消耗的目的。 In the mobile communication carrier operating costs, the power consumed by the base station subsystem accounted for a large part, if this part can be effectively reduced expenditure, operating costs and substantial savings will achieve savings in energy consumption.

基站分系统BSS主要负责GSM系统中与无线及传输相关的系统功能。 The base station subsystem BSS is mainly responsible for the GSM system and the transmission associated with the wireless system function. 如提供对无线资源的管理,向交换分系统提供与陆地有线信道对应的无线信道的分配,建立和释放,向移动用户提供通过有限的无线资源接入到网络的方法,以及控制移动用户越区切换管理等功能。 The management of the radio resources provided, allocation of radio channels corresponding to provide landline switching subsystems channel to establish and release, there is provided a method by limited wireless resources to the network access to mobile users, and to control handover the mobile user switch management.

实验数据表明,基站系统在每天24小时的每个小时内业务负载量是不同的,业务最高峰时业务量和最低时相差可以达十倍之多,但是即使在业务量最少的时段,现行的基站系统也是全功率运转的,这其中有一部分功率被浪费掉了,如果能够使基站根据业务量自动调整参与运行的处理单元数量,在业务量低谷时段关闭不必要的处理单元,则可以达到节省电力的目的。 Experimental data show that the base station system within 24 hours of each day, hour traffic load are different, when the traffic volume and traffic peak difference can be up to ten times as much as the minimum, but even the least traffic period, the current the base station system is operating at full power, of which a part of the power is wasted, if the base station is possible to automatically adjust the amount of traffic involved in the number of processing units running in a processing unit turn off unnecessary low traffic period, the savings can be achieved the purpose of power.

基站分系统主要有基站控制器BSC和基站收发信站BTS两个功能实体所组成。 The base station subsystem mainly composed of a base station controller BSC and the base transceiver station BTS two functional entities. 基站控制器实现的功能主要有: The base station controller to achieve the main function:

陆地信道管理,对A接口和Abis接口进行管理控制,执行BSC-BTS之间信道的分配(包括物理信道和逻辑信道)。 Terrestrial channel management, and the A interface of Abis interface for management control, performing channel allocation between BSC-BTS (including the physical and logical channels). 由于无线信道与Abis接口的陆地信道分配是一一对应的关系,因而BSC也就是负责无线接口上的信道分配。 Since the radio channel and a terrestrial channel Abis interface assignment is one to one relationship, thus BSC is responsible for channel allocation on the radio interface.

无线信道管理,执行对无线信道结构的管理(即逻辑信道的组合,物理信道的映射等),向用户分配专用信道,对射频信道的功率控制等。 Radio channel management, radio channel management structure performed (i.e., a combination of logical channels, the mapping of physical channels, etc.), dedicated channel is allocated to a user, the RF channel power control.

负责三种越区切换:BSC内部的小区内部,BSC内部的小区间以及BSC之间的业务越区切换。 Responsible for three kinds of handover: handover operations between the internal cells inside the BSC, inter-BSC cell and the interior of the BSC handover.

操作维护功能'包括对业务的测量和对某一移动站的观察。 The maintenance functions' comprises a measurement and observation of the traffic on a mobile station. BSC控制着这些观察和测量的触发,取样,收集数据,建立文件和传输文件到操作维护中心OMC-B。 BSC controls the triggering of these observations and measurements, sampling, data collection, transfer files to create a file, and operation and maintenance center OMC-B.

支持小区分裂或扩充,增加或减少基站收发信站的部分或全部设备,增加或减少无线陆地信道等。 Support division or cell expansion, increasing or decreasing some or all of the base transceiver station apparatus, increased or decreased wireless terrestrial channel and the like.

基站收发信站主要具有处理基站分系统有关无线接续的功能。 The main base transceiver station having a base station subsystem about wireless connection processing function. 包括:完成逻辑信道到物理信道的映射(包括信道组合等)。 Comprising: a complete logical to physical channel mapping (including a combination of channels, etc.). 对移动站随机接入和越区切换接入的检测。 The mobile station random access and handover access detection.

对无线信道的编码/解码,信道调制解调,交织和去交织,数据的加密和解密,TDMA帧建立,跳频等功能。 Radio channel encoding / decoding, channel modulation and demodulation, deinterleaving and interleaving, encryption and decryption of data, TDMA frame is established, frequency hopping function.

处理对其设备内各部分的操作维护功能。 Processing operations of the respective portions in its maintenance functions.

当移动站从空闲模式变化到专用模式,向基站发起接入请求,原因可能是下述之一: When the mobile station changes from idle mode to dedicated mode, an access request to the base station, may be one of the following reasons:

1. 执行小区位置更新。 1. Perform a cell location update.

2. 响应寻呼。 2. respond to a page.

3. 建立呼叫,包括附加业务请求,发送短信息请求。 3. The call is established, including an additional service request, sending a short message request.

无论哪种原因,移动站都是向基站发出信道接入请求,基站收发信站检测到该请求之后,交付给基站控制器由其给移动站业务分配信道并建立连接,从而移动站可以进行通信业务。 Whatever the reason, the mobile station is sent to a base station channel access request, the base transceiver station after the request is detected, delivered to the base station controller to the mobile station by its assigned traffic channel and establish a connection, whereby the mobile station can communicate business. 信道请求和分配过程如图1所示。 Channel request and assignment process is shown in Fig.

切换过程发生于网络指定移动站接入其他小区的信道,发生的原因多种多样,但切换决定权在基站控制器。 Handover process occurs in a given mobile network cell station access to other channels, the causes varied, but the handover decision in the base station controller. 一旦新小区选定,移动站就必须与原小区和新小区的管理实体进行传输协调。 Once a new cell is selected, the mobile station must be coordinated with the original transmission and the new cell cell management entity. 该处理总是由两个主要过程组成: This process always consists of two main processes:

(1) 基站控制器首先触发一系列事件,用以建立一条可能的路径。 (1) First, a base station controller triggers a series of events, to establish a possible path. 一旦路径建立,则向移动站发送切换指令。 Once the path is established, switching instruction is sent to the mobile station.

(2) 移动站按指令接入新信道,并触发网络交换路径,释放原路径。 (2) The mobile station according to instructions accessing the new channel, and trigger the network switching path, release the original path. 切换执行过程如图2所示。 2 handover execution procedure shown in FIG.

所谓的交换点可以是原BSC,也可是新BSC或者是其他单元,取决与越区切换的种类。 The switching point may be called the original BSC, but also the new BSC or other means, depending on the type of handover. 交换点负责建立到新的BSC所必须的有线资源和无线资源。 Exchange points responsible for establishing resources to wired and wireless resources necessary for the new BSC. 在本发明中涉及的越区切换均是BSC内部BTS之间切换,所以交换点就是原BSC。 Handover according to the present invention are switched between BSC internal handover BTS, so the switching point is the original BSC.

无论哪种类型的切换,当交换点收到切换完成信息后,都开始以某种适当的方式释放原来的路径和无线资源。 No matter what type of switch, after receiving the handover completion message exchange point, are beginning to release the original path and the radio resources in some appropriate manner.

若NEXT=b,则不采取任何动作; If NEXT = b, no action is taken;

若NEXT<b,则说明上一个周期中业务量呈减少趋势,应关闭不需要的无线收发信台以节省电能。 If NEXT <b, then the cycle was on a traffic decreasing tendency, need not be shut down the radio transceiver station to save power.

关闭的程序如下: Close procedure is as follows:

为当前开启的无线收发信台赋予l〜b的编号作为权重,业务负荷最大者为b,最轻者为1, 如遇相同者,则随机取其一赋以较大的权重。 L~b given for the current open number as a wireless transceiver station weights greatest traffic load is b, 1 is the lightest, such as those in case of the same, whichever is randomly assigned with a greater weight.

则l〜(b-NEXT)号无线收发信台将被关闭。 The l~ (b-NEXT) No. radio transceiver station will be closed. 按编号由低至高,依次将其上的业务转移至保留的无线收发信台并将其关闭。 By number from low to high, which in turn transferred to the traffic on the radio transceiver station and retained closed.
