Description

一种无线通信系统中信息虚拟双向的方法及装置 Information in a wireless communication system method and apparatus for bidirectional virtual

技术领域 FIELD

本发明涉及无线通信系统中信息发送和接收的方法,尤其是信息虚拟双向交互的方法。 The present invention relates to a wireless communication system and receiving method for transmitting information, in particular information of the virtual two-way interactive methods.

对于第一种方案,由主端定义若干个邮箱,每个邮箱对应一类或若干类信息。 For the first embodiment, the main end define several mailboxes, each corresponds to one type or several types of information. 用户通过电话或互联网对某些类信息进行订阅。 Users subscribe to certain types of information over the phone or Internet. 对于主端,当某类信息在不同时段存在相同点播操作时,主端将此类信息进行重复发送,从而降低了信道的使用率,浪费了信道资源。 For the master, when certain information is present in the same demand at different times of operation, the master terminal transmits this information repeatedly, thereby reducing the usage of the channel, a waste of channel resources. 对于终端,如果要增减某些信息,只能通过改变邮箱地址来实现,这样只能控制邮箱的收与不收,无法控制邮箱内的信息量。 For the terminal, if you want to increase or decrease certain information, it can only be achieved by changing the e-mail address, so can only control the mailbox and receive no income, can not control the amount of information in the mailbox. 如果每一个邮箱只对应一个独立信息,势必造成邮箱地址使用数量的大量增加,造成系统地址码的浪费和系统资源开销的增加。 If each mailbox corresponds to only one independent information, it will inevitably result in a significant increase in the number of e-mail address to use, resulting in increased waste system address code and system resource overhead. 实际中,地址码的使用数量和系统资源开销的增加,都将会受到主端系统及终端系统的较大限制。 In practice, use of the system resource overhead and increasing the number of address code, will have more restricted master end system and terminal system.

对于第二种方案,在整个传输系统中必须建立一条反向无线信道,用来接收终端发送的数据。 For the second embodiment, a reverse radio channel must be established throughout the transmission system, to receive the data sent by the terminal. 在反向信道带宽较窄的情况下,反向数据将随着终端数量的增加而增加,反向信道中将会出现信道拥塞的情况,使信息传输出现延迟,甚至引起主端系统的崩溃。 In the reverse channel bandwidth is narrow, the reverse data will increase the number of terminals increases, channel congestion situation of reverse channel will appear, so that information transmission delays, and even cause collapse of the primary side of the system. 对于手持式可移动终端而言,当其处于开机首次登陆网络或由一个蜂窝移动到另一个蜂窝时,终端都需要进行网络注册,此状态下和终端数据回传时,要求终端提供较大的工作电流来支持终端射频模块的启用,耗电量的增加将会影响终端的使用性能。 For hand-held mobile terminals may be, when it is on the first landing of a mobile network or cell to another, the terminal needs to be registered to a network, and the terminal data when the return this state, the terminal requires to provide greater operating current to support terminal RF module is enabled, power consumption increases will affect the performance of the terminal.

此外,为存储信息数据的订阅数据及接收到的数据,在数据接收装置中还包含存储装置。 Further, the data storage information for the subscription data and the data received in the data receiving apparatus further comprises a storage device.

由上述本发明采用的技术方案可以看出,本发明完全实现了本发明的目的,本发明的优点在于以下几个方面:(1)由于本发明在数据发送端使用要发送信息数据的信息特征和发送该信息的信道特征形成虚拟双向信令,在数据接收端,根据信息订阅情况进行信息的接收,这样,可以使数据接收端避免接收和保存大量自己不需要的信息,显著降低了终端功耗,同时使有限的存储空间内更多地保存自己想要的信息,从而更加有效地使用了存储空间;由于本发明较好地解决发送大容量信息内容与数据接收端电能有限、存储空间有限的矛盾,数据发送端就可以采集尽可能多的信息内容以供用户进行个性化选择。 As can be seen from the above technical solutions employed in the present invention, the present invention fully achieves the object of the present invention, the advantage of the invention lies in the following aspects: (1) Since the present invention is used in the data transmission side to send data to the feature information and channel characteristics to transmit the information to form a virtual bidirectional signaling, at the data receiving end, receiving information from the information subscriptions, this can make the data receiving terminal to avoid receiving and storing a large number of their unnecessary information, significantly reducing terminal function consumption, while the more information they want to save the limited storage space, so that more efficient use of storage space; due to the present invention solves large volume of information content transmitted with the data receiving terminal is limited power, storage space is limited contradictions, data sender can collect as much information as content for user personalization options.

(2)由于本发明采用信令与信息间隔发送的数据发送方式,避免了双向传输结构中的信道带宽不足所出现的数据传输延时和信道拥塞情况;同时,由于本发明不需要再占用信道回传信息,而是通过一次性广播方式发送信息,极大提高了信道的利用率。 (2) Since the present invention employs the data transmission method signaling information is transmitted every avoid data transmission delay and channel congestion channel bandwidth bidirectional transmission structure deficiencies occurring; Also, since the present invention does not require re-occupation of the channel return information, but the information is sent through a one-time broadcast, greatly improve the utilization of the channel.

(3)由于本发明用于订阅信息的信息目录表由数据发送端提供,供用户订阅信息使用,订阅后的信息目录表存储在数据接收端中,这样,在数据接收端可以实现信息的主动控制接收权力,在数据接收端即可以实现订阅的即时生效,而不需要再借助其他资源来实现信息订阅的修改。 (3) Since the present invention for the subscription information is provided by the table of contents information data sender, using the subscription information for the user, the table of contents information stored in the subscription data receiving end, so that, at the receiving end of data information may be implemented Active receiving power control, data reception terminal which can realize subscription with immediate effect, to achieve without the need to modify the information subscribe to the aid of other resources. 另外,这种方式的用户订阅信息的详细程度可以由数据发送端任意确定,增加了用户订阅信息的灵活性。 Further, in this way the user subscription level of detail may be arbitrarily determined by the data transmitting side, increasing the flexibility of the user subscription information.

(4)由于本发明的用户终端对接收到的信令进行身份验证,只有通过身份验证后才能接收信息,因此应用本发明,便于对用户进行分类管理和服务。 (4) Since the user terminal of the present invention, signaling the received authentication information received only authenticated, so the application of the present invention, facilitates the user to classify and manage services.

根据本发明所述的方法,第一,将系统传输信道划分为信令信道和数据信道,信息内容和信令在不同的信道上发送。 The method of the present invention, first, the system is divided into a transmission channel signaling channels and data channels, and signaling information content transmitted on different channels. 上述信道的划分可以是逻辑上的划分,也可以是物理上的划分;而且要将系统的所有终端设置为对信令信道打开、对数据信道关闭的的状态,以使数据接收端在没有收到虚拟双向信令之前,不会接收和存储任何受控信息;第二,要制定数据发送端和用户终端处理信息的协议或约定,以使数据发送端和用户终端能够按共同的标准处理信息。 Dividing said channel may be divided into logical, or may be divided physically; and all terminals To the system provided for the signaling channel is opened, the data channel closed state, so that the data receiving end is not received prior to the virtual bidirectional signaling, and does not receive any controlled information store; second, to develop a protocol data transmitting end and the information processing terminal or the user agreed to make the data transmission terminal and the user terminal capable of processing information according to a common standard .

图1是本发明的信息虚拟双向方法的流程图。 1 is a flowchart of the present invention, the information of a virtual two-way method.

在数据发送端:执行步骤1,提取要发送的信息数据的信息特征,选择要发送该信息数据的信道,提取该数据信道的信道特征,然后将上述信息特征和信道特征结合,形成虚拟双向信令并打包成数据包,然后发送包含要发送信息数据的信息特征和传送该信息数据的信道特征的虚拟双向信令数据包。 In the data transmission side: step 1, information of the feature information extracting data to be transmitted, to select the transmission channel the information data, extract the channel characteristics of the data channel, then the combination of the above information characteristics and channel characteristics, to form a virtual bi-directional channel so packaged into packets and then transmits feature information to be transmitted containing information data and transmitting the information channel wherein the virtual bidirectional signaling data packet. 在本步骤中,为加强数据的安全,也可以对所述数据包进行加密、压缩等处理。 In this step, in order to strengthen the security of the data, it may encrypt the packet data, compression processing.

接着进行步骤2,间隔一定的时间间隔后,发送信息数据;在发送信息数据之前,在要发送的信息数据前加入一个信息头,所述信息头的内容与所述信息目录表的数据结构以及虚拟双向信令中的信息特征相适应。 Followed by Step 2, after a certain interval of time interval, transmit information data; information before transmitting data, a header is added before the information data to be transmitted, the data structure of the content information and the header information and directory table information feature virtual two-way signaling fit.

此外,在数据发送端,还要有发送供用户订阅信息的信息目录表,以方便用户在数据接收端订阅信息。 Further, in the data transmitting side, but also for the user subscription information transmitting list information to the data reception terminal user subscription information.

在数据接收端:首先进行步骤3,接收数据发送端发送的数据;接着进行步骤4,判断接收到的数据是虚拟双向信令数据还是信息数据,如果是虚拟双向信令数据,根据该虚拟双向信令数据和数据接收端订阅的数据打开或关闭数据接收装置中相应信道的地址开关。 In the data receiving end: Step 3 is first data, receiving data sent by a transmitter; followed by a step 4, whether the received data is a virtual bidirectional signaling data or information data, if the data is a virtual bidirectional signaling, based on the bi-directional virtual signaling data and a data reception terminal to open or close subscription data in the data receiving apparatus corresponding to the address switch channels. 也就是说,在接收到虚拟双向信令数据后,还要判断数据接收端订阅的数据与虚拟双向信令中的信息特征所描述的信息数据是否相同,如果相同,打开数据接收装置中相应信道的地址开关准备接收所述信息特征所描述的信息数据,否则关闭数据接收装置中相应信道的地址开关拒绝接收该信息数据。 That is, after receiving the dummy bidirectional signaling data, but also to determine whether the information receiving terminal subscribed data and information data wherein the virtual bidirectional signaling as described in the same, if the same, the data receiving apparatus corresponding open channel the switch is ready to receive the address information of the data information of the features described, the data receiving apparatus is otherwise turned off respective channel address switch refuses to accept the message data. 这样,数据发送端单向发出的虚拟双向信令,控制了数据接收装置对虚拟双向信令中描述的数据的接收。 Thus, bidirectional data transmission terminal virtual unidirectional signaling sent, the control data receiving means for receiving data in virtual bidirectional signaling described. 因此,如果数据接收端接收到的是信息数据,并且该信息数据是本数据接收端订阅的数据,则接收该信息数据。 Thus, if the data information is received by the receiver data, the message data is present and the data reception terminal subscription data, the message data is received. 判断信息数据是否为该数据接收端订阅的数据,可以通过判断信息数据的信息头与相应信令的指示是否相符实现。 Determining whether the data information subscribed data receiving end for the data, by determining whether the message header information data indicating respective signaling consistent implementation.

在上述步骤4中判定接收的数据是虚拟双向信令数据后,还有一个判断步骤,对接收的虚拟双向信令进行身份验证,即判断该条信令该数据接收端是否有权接收该条信令,如果未通过验证,说明该数据接收端无权处理该条信令以及信令所描述的信息数据,因此终止所述步骤4以后的操作,如果通过验证,说明该条信令以及信令所描述的信息数据属于本数据接收端有权处理的范畴,因此继续所述步骤4。 After it is determined in step 4 the received data is a virtual bidirectional signaling data, and a determination step of receiving virtual bidirectional signaling for authentication, i.e. signaling data piece is determined whether the receiver is entitled to receive the article signaling, if not verified, the data indicates that the receiving side has no authority piece of signaling information and signaling data as described, thus terminating the 4 subsequent steps, if verified, and a signaling channel strip described order information data described in the data receiver belongs to the scope of the right to process, thus continuing the step 4.

根据本发明的实施,还可以在数据接收端订阅信息,根据所述接收到的信息目录表进行信息的订阅,并将订阅数据存储在接收端的存储器中。 According to an embodiment of the present invention may also be in the data receiving terminal subscription information, subscription information according to the received table of contents information and the subscription data stored in memory at the receiving end. 所述信息目录表是所有有权的数据接收端都能接收到的公共信息,如果数据接收端没有接收到新的信息目录表,则只能按照已存在的前次订阅的信息目录表接收信息数据。 The table of contents information is entitled to all of the data receiving end can receive public information, if the data receiving end does not receive new information table of contents, you can only receive information in the information table of the previous subscription already exists data. 实际中也可以在数据接收端设定信息目录表的生存周期等于数据发送端的发送周期,若数据接收端在规定的时间内没有收到新的信息目录表,自动删除当前的旧信息目录表。 The actual data can also set the receiving end of the life cycle information table of contents equal to the transmission cycle data transmitting end, if the data receiving end does not receive new information catalog tables within a specified period of time, automatically delete old messages current table of contents. 如果数据接收端没有信息目录表,则只能在接收到信息目录表并订阅信息后才能接收到所订阅的信息。 If the data receiver is not information table of contents, you can only subscribe to information received after receiving the information table of contents and subscription information.

图2是在用户终端执行信息接收的过程。 FIG 2 is a process executed in the user terminal information received. 在步骤A,进行信息的接收,如果接收到信息,在步骤B,判断接收到的信息是虚拟双向信令信息还是数据信息,如果是虚拟双向信令信息,步骤C进行虚拟双向信令的处理,否则在步骤H进行信息数据的接收;在步骤C,对接收的虚拟双向信令进行身份验证,即用户终端判断本用户是否有权接收该条虚拟双向信令,如果未通过验证,说明该用户终端无权接收该虚拟双向信令,因此回到步骤A继续接收信息,否则,在步骤D判断用户是否已订阅虚拟双向信令中的信息特征所描述的信息数据,该判断是根据用户订阅信息的结果完成的,用户通过信息目录表订阅信息,该信息目录表由数据发送端提供,供用户订阅信息使用,订阅后的信息目录表存储在用户终端中。 In Step A, receiving information, if the information is received in step B, and the received information is determined to be a virtual bidirectional signaling information or data information, if it is a virtual bidirectional signaling information, step C virtual processing bidirectional signaling otherwise, the received message data in step H; in step C, and the received virtual bidirectional signaling for authentication, i.e. the user terminal determines whether the user is authorized to receive this piece of dummy bidirectional signaling, if not verified, indicating that the a user terminal entitled to receive the virtual bidirectional signaling, so back to step a to continue receiving the information, otherwise, in step D is determined whether the user has subscribed information characteristic of information data in the virtual bidirectional signaling as described, the determination is based on user subscription result information is completed, the table of contents information through the user subscription information, the table of contents information provided from the data transmitting side, for the user to use the subscription information, the directory table stores the information in a user terminal subscription. 如果用户已订阅该虚拟双向信令所描述的信息,步骤E继续虚拟双向信令的后续处理,否则步骤F继续虚拟双向信令的后续处理;在步骤E,在数据接收端中打开虚拟双向信令中的信道特征描述的信道的开关,使数据接收端能够接收从该信道中传来的信息,然后步骤A继续接收信息;在步骤F,判断虚拟双向信令中的信道特征描述的信道开关在数据接收端中是否关闭,如果关闭,步骤A继续接收信息,否则在步骤G,在数据接收端中关闭虚拟双向信令中的信道特征描述的信道的开关,使数据接收端不能够接收从该信道中传来的信息,然后步骤A继续接收信息;在步骤H,在数据接收端中,通过已打开开关的信道接收订阅的数据,接收完毕后自动关闭相应数据信道,然后回到步骤A。 If the user has subscribed to the virtual bidirectional signaling information as described in Step E go on a virtual bidirectional signaling for subsequent processing, or virtual bidirectional signaling step continues subsequent processing F.; In step E, a virtual bi-directional channel open at the data receiving end channel switching channel characteristics make the described, so that the data receiving terminal capable of receiving information transmitted from the channel, then step a to continue receiving the information; in step F., the channel characteristic determines the virtual bidirectional signaling described channel switch is closed at the data receiving end, if closed, step a to continue receiving the information, or G at steps to close the switch channel channel characteristic virtual bidirectional signaling described in the data receiving end, so that the data receiver can not receive from the the channel information transmitted and received information continues in step a; in step H, the data at the receiving end, the received subscription opened by the switch channel data, is completed automatically turn off after receiving the corresponding data channel, and then returns to step a .

总之,在数据发送端提取要发送的信息的特征和发送该信息的数据信道的特征,用以形成控制用户接收信息的虚拟双向信令,用户终端根据接收的虚拟双向信令以及用户对信息的需求即可有选择地接收信息。 In short, the data transmission terminal extracting characteristic information to be transmitted and the transmission channel characteristic data of the information, the user receives the control information to form a virtual bidirectional signaling, the user terminal information received virtual bidirectional signaling and user needs to receive information selectively. 数据发送端的虚拟双向信令是对所有用户广播式发送,而不同用户却可以根据虚拟双向信令及自己对信息的需求有选择地接收信息,使得上述控制所有用户接收信息的信令客观上起到了对不同用户的控制作用,因此,上述由数据发送端单向发送的虚拟双向信令事实上起到了数据发送端和用户端双向的控制作用,构成了控制用户信息接收的虚拟双向信令。 Virtual bidirectional signaling data sender is sending broadcast to all users, but different users can selectively receive information based on the virtual bidirectional signaling and their information needs, such that the control signaling for all users receiving information from the objective to control the effect of different users, and therefore the data transmission from the end of the one-way transmission in fact a virtual bidirectional signaling plays a role in controlling bidirectional data transmitting side and the UE, constitute virtual bidirectional signaling information received by the user control. 由于上述通过数据发送端形成的虚拟双向信令来控制用户终端有选择地接收信息的方案已经由本发明详细公开,在此基础上的任何变化都应在本发明的保护范围之内。 Since the above-described virtual bidirectional signaling via the data transmission side is formed to control a user terminal to selectively receive information of the program by the present invention has been disclosed in detail, on the basis of any changes should be within the scope of the present invention.
