“小區(qū)廣播”--是通過小區(qū)廣播信道(CBCH)將信息(如地理位置、天氣狀況等信息)傳到手機,再由用戶選擇接收的一種功能,通過此功能可向用戶提供位置信息,天氣預(yù)報等服務(wù)。 是向中國移動的手機客戶按區(qū)域、按頻道發(fā)送各種實時、動態(tài)的分類信息的業(yè)務(wù)。它將使您的手機如同收音機一樣,可以隨時隨地接收您感興趣的頻道內(nèi)容,讓您充分享受通信新生活。 小區(qū)廣播的特點 1、免費資訊:客戶通過小區(qū)廣播接收到的信息全部免費。 2、自主性:您可自主選擇頻道,設(shè)置不同頻道的開關(guān),接收您需要的信息。 3、區(qū)域性:可在不同的小區(qū)內(nèi)接收到不同的信息。 *不同型號的手機“小區(qū)廣播”的名稱不同,如摩托羅拉、西門子為“小區(qū)廣播”;諾基亞為“信息臺”;愛立信、三星為“小區(qū)信息”。其它型號手機請參照手機說明書。 *適用對象:全球通、神州行,以及在本地區(qū)內(nèi)漫游的外地客戶。 小區(qū)廣播的應(yīng)用范圍? 1. 應(yīng)用方向 預(yù)警 小區(qū)廣播基于位置,速度快,適用于預(yù)警信息發(fā)布。 公眾信息 向公眾發(fā)布政府公告,氣象預(yù)報等公眾信息。 提高品牌認知度 向手機用戶提供免費和增值業(yè)務(wù),提升品牌。 2. 使用方式 預(yù)警信息發(fā)布 自然災(zāi)害、事故災(zāi)難、衛(wèi)生事件、安全事件預(yù)警 政府及公共事業(yè)部門 招商引資、信息送達、公告宣傳、傳播理念 會展中心、體育中心 現(xiàn)場介紹、場地指引 重要集會、大型慶典活動 活動指導(dǎo) 機場、車站、碼頭 城市介紹、景點介紹、城市天氣 旅游景點 景點介紹、整合信息、景點天氣 品牌宣傳 產(chǎn)品推介、品牌宣傳、促銷互動 小區(qū)廣播與手機短信結(jié)合能夠互動,可以實現(xiàn)如下增值業(yè)務(wù): 小區(qū)廣播問卷調(diào)查 投訴建議 短信抽獎活動 Q:能否接收多個頻道? A:根據(jù)手機接收性能的不同,部分手機可以,部分手機不行。隨著每個頻道信息發(fā)送密度的加大,我們建議用戶盡量不要同時接收多個頻道,以免影響接收效果。 Q:所有的手機都能收到小區(qū)廣播嗎? A:絕大多數(shù)手機都支持小區(qū)廣播,但是需要注意的有以下幾點: *現(xiàn)在的小區(qū)廣播只有中文內(nèi)容,所以要求是中文手機,部分只是中文菜單的手機(中文字庫不完整)也會不正常。 *必須在手機上進行開通操作才能接收。 Q:一般多少分鐘一條信息? 3分鐘 Q:我在哪里能夠了解小區(qū)廣播業(yè)務(wù)? A:您可以通過廣東移動的1860咨詢熱線;廣播新干線客服熱線83510305、www.gmcc.net了解本業(yè)務(wù),或點擊小區(qū)廣播專用網(wǎng)站()。另外,您還可以在廣東移動的各個營業(yè)點索取小區(qū)廣播的宣傳單張。 Q:小區(qū)廣播在什么時間播出? A:具體時間隨頻道不同而不同,詳細情況請看我們在宣傳單張、網(wǎng)站和小區(qū)廣播播放內(nèi)容中的介紹。 Q:誰能接收到小區(qū)廣播? A:只要是中國移動的手機用戶,包括全球通、動感地帶、神州行(包括大眾卡)用戶,都可以在廣州市區(qū)范圍內(nèi)(包括番禺、花都、從化、增城)接收到小區(qū)廣播。 Q:一定要設(shè)置小區(qū)廣播的頻道嗎? A:是的,要收到小區(qū)廣播信息必須打開小區(qū)廣播的接收設(shè)置,同時將有內(nèi)容發(fā)送的頻道號輸入。 Q:收到新的信息會沖掉舊的信息嗎? A:是的。如果不察看,收機上只能保留下最新的信息,舊的信息會被沖掉。就象看電視一樣,如果某個時間的節(jié)目你沒有看,它就會過去。 Q:小區(qū)廣播的信息能存儲嗎? A:部分手機能存,部分手機不能存;但是小區(qū)廣播信息的存儲位置和短信息的存儲位置是不一樣的;而且小區(qū)廣播的信息通常只能存最新的一條。通常手機可以翻屏顯示,就能夠存,只能滾動顯示,一般不能存。 Q:為什么我的手機接收信息時顯示不完整? A:有限制,我們實際播出的內(nèi)容最大字數(shù)為80-120個字(包括標點)。小區(qū)廣播理論值上每條信息最大可以發(fā)送600字,但是因為各款手機接收性能不一致,如三星的部分型號手機只能接收40字,顯示不完整,所以取較低的發(fā)送字數(shù)。 The CBS service is analogous to the Teletex service offered on television, in that like Teletex, it permits a number of unacknowledged general messages to be broadcast to all receivers within a particular region. CBS messages are broadcast to defined geographical areas known as cell broadcast areas. These areas may comprise of one or more cells, or may comprise the entire PLMN. Individual CBS messages will be assigned their own geographical coverage areas by mutual agreement between the information provider and the PLMN operator. CBS messages may originate from a number of Cell Broadcast Entities (CBEs), which are connected to the Cell Broadcast Centre. CBS messages are then sent from the CBC to the BTSs, in accordance with the CBS''s coverage requirements. The CBS message comprises of 82 octets, which, using the default character set, equates to 93 characters. Up to 15 of these messages (pages) may be concatenated to form a macromessage. Each page of such macromessages will have the same message identifier (indicating the source of the message), and the same serial number. Using this information, the MS is able to identify and ignore re-broadcasts of already received messages. CBS messages are broadcast cyclically by the BTS at a frequency and for a duration agreed with the information provider. The frequency at which messages are repeatedly transmitted will be dependent on the information that they contain; for example, it is likely that dynamic information such as road traffic information, will require more frequent transmission than weather information. The repetition period will also be affected by the desire for messages to be received by high speed mobiles which rapidly traverse cells. All suitably equipped mobiles within the catchment area of the transmitting BTS will be able to receive the broadcast messages, provided that they are switched on and in the idle state. CBS messages may be broadcast on two different cell broadcast channels, which are characterized by different QoS. A MS is always able to read the basic channel (see [8]). The reading of the extended channel may collide with other tasks of the MS. Therefore the probability of receiving a CBS message on the extended channel is smaller than on the basic channel. The reading of the extended channel for MSs is optional. The scheduling on the channels will be done independently. To permit mobiles to selectively display only those messages required by the MS user, CBS messages are assigned a message class which categorises the type of information that they contain and the language in which the message has been compiled. Through the use of appropriate MMI, the user is then able to ignore message types that he does not wish to receive, e.g. advertising information or messages in an unfamiliar language.
