技术领域Technical Field
本发明涉及广播网络传输技术领域，尤其涉一种移动通信网络辅助广播网络的收发方法及其装置。The present invention relates to the technical field of broadcast network transmission, and in particular to a method and device for transmitting and receiving broadcast networks assisted by mobile communication networks.
背景技术Background technique
在现有的广播网络传输机制中，通常不涉及上行链路，即用户仅单向的接收广播网络下发的业务，而不上传任何信息，若用户接收到的内容发生丢包情况，也无法向广播网络侧进行反馈，进而导致广播业务的接收质量较差。此外，由于广播网络中的广播基站的覆盖范围通常较大，对于处于覆盖范围边缘、有覆盖阴影或高速移动的用户，发送丢包的情况将更为严重。In the existing broadcast network transmission mechanism, the uplink is usually not involved, that is, the user only receives the services sent by the broadcast network in a one-way manner, and does not upload any information. If the content received by the user is lost, it cannot be fed back to the broadcast network side, resulting in poor reception quality of the broadcast service. In addition, since the coverage range of the broadcast base station in the broadcast network is usually large, the packet loss will be more serious for users at the edge of the coverage range, in coverage shadows, or moving at high speed.
因此，现亟需一种能够提高广播网络业务的传输质量，进而可以提升广播网络系统性能的方法。Therefore, there is an urgent need for a method that can improve the transmission quality of broadcast network services and thus improve the performance of the broadcast network system.

具体实施方式Detailed ways
下面结合附图和具体实施例对本发明作进一步说明，但不作为本发明的限定。The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.
本发明针对广播网络业务传输，提供一种移动通信网络辅助广播网络的传输方法，如图1所示，包括：The present invention provides a method for transmitting broadcast network services by a mobile communication network, as shown in FIG1 , comprising:
广播网络将第一信息发送给用户；以及向移动通信网络发送对应于第一信息的第二信息，第一信息的第一序列号与第二信息的第二序列号呈对应关系；The broadcast network sends the first information to the user; and sends the second information corresponding to the first information to the mobile communication network, wherein the first serial number of the first information corresponds to the second serial number of the second information;
使移动通信网络在接收到用户的反馈信息后，根据反馈信息指示的用户对第一信息的接收状态，将对应的第二信息传输至用户。After receiving feedback information from the user, the mobile communication network transmits corresponding second information to the user according to the user's reception status of the first information indicated by the feedback information.
具体地，考虑到广播网络的单向性，无法在用户未成功接收到广播网络下发的信息时进行及时调整，本发明基于移动通信网络的双向性，提供一种移动通信网络辅助广播网络的传输方法，在用户未成功接收广播网络下发的第一信息时，用户可以根据对第一信息的接收状态，生成反馈信息并上传至移动通信网络，以接收到移动通信网络从广播网络收到的对应于第一信息的第二信息，实现信息的正确传输，由此可见，本发明提供的移动通信网络辅助广播网络的传输方法，通过移动通信网络的双向传输，及时获取用户对于广播业务的接收状态，并可以向用户进行补包重传，提高广播网络业务传输质量，提升广播网络系统性能。Specifically, considering the unidirectionality of the broadcast network, it is impossible to make timely adjustments when the user fails to successfully receive the information sent by the broadcast network. The present invention is based on the bidirectionality of the mobile communication network and provides a transmission method for a mobile communication network to assist the broadcast network. When the user fails to successfully receive the first information sent by the broadcast network, the user can generate feedback information based on the reception status of the first information and upload it to the mobile communication network, so as to receive the second information corresponding to the first information received by the mobile communication network from the broadcast network, thereby realizing the correct transmission of the information. It can be seen that the transmission method for a mobile communication network to assist the broadcast network provided by the present invention can obtain the user's reception status of the broadcast service in a timely manner through the bidirectional transmission of the mobile communication network, and can retransmit the packet to the user, thereby improving the transmission quality of the broadcast network service and enhancing the performance of the broadcast network system.

In the specific numbering process, consecutive first serial numbers can be sequentially numbered according to the order in which the first information arrives, wherein the value of the first serial number can be from small to large or from large to small; then, the corresponding second information is generated through operations such as copying according to the first information, and the second serial number corresponding to the first serial number is included in the second information; finally, the second information is transmitted to the mobile communication network.
需要注意的是，此时的第一序列号和第二序列号呈等值关系，即第一信息和第二信息的数据部分相同，序列号也相同。It should be noted that at this time, the first serial number and the second serial number are in an equal value relationship, that is, the data part of the first information and the second information are the same, and the serial numbers are also the same.

The PDCP sequence numbers obtained by the above two mapping methods have a specific corresponding relationship.
进一步地，对PDCP序列号进行映射方式可以为等值映射，固定倍数映射，可以使固定差值映射。其中，当上述两个PDCP实体对两个PDCP序列号进行映射方式相同均为等值映射时，而第一序列号和第二序列号又相同时，对于第一信息而言，它的第一PDCP序列号与第一序列号相同，对于第二信息而言，它的第二PDCP序列号与第二序列号相同，此时第一信息和第二信息分别具有相同第一序列号和第二序列号，也具有相同的第一PDCP序列号和第二PDCP序列号。Furthermore, the mapping method for the PDCP sequence number can be equal value mapping, fixed multiple mapping, or fixed difference mapping. Among them, when the two PDCP entities map the two PDCP sequence numbers in the same way, which is equal value mapping, and the first sequence number and the second sequence number are the same, for the first information, its first PDCP sequence number is the same as the first sequence number, and for the second information, its second PDCP sequence number is the same as the second sequence number. At this time, the first information and the second information have the same first sequence number and second sequence number, respectively, and also have the same first PDCP sequence number and second PDCP sequence number.
再进一步地，广播基站中的第一PDCP实体和/或移动网络基站中的第二 PDCP实体可以获知的自身对PDCP序列号进行编号时的映射方式，和/或对方对 PDCP序列号进行编号时的映射方式，和/或第一信息和第二信息通过两种映射方式所得到的PDCP序列号所呈的特定的对应关系。这三者可以通过以下方式的任意组合获知：协议规定和网络通知，在网络通知中又可以包括：广播核心网通知、广播接入网通知、广播应用层/服务端通知、移动通信核心网通知、移动通信接入网通知、移动通信应用层/服务端通知。Furthermore, the first PDCP entity in the broadcast base station and/or the second PDCP entity in the mobile network base station can obtain the mapping method when numbering the PDCP sequence number, and/or the mapping method when the other party numbers the PDCP sequence number, and/or the specific corresponding relationship between the PDCP sequence numbers obtained by the first information and the second information through the two mapping methods. These three can be obtained through any combination of the following methods: protocol provisions and network notifications, and the network notifications can include: broadcast core network notifications, broadcast access network notifications, broadcast application layer/server notifications, mobile communication core network notifications, mobile communication access network notifications, and mobile communication application layer/server notifications.
本发明的一种实施方式中，移动通信网络对第二信息的处理过程还包括：首先，缓存第二信息；In one embodiment of the present invention, the processing of the second information by the mobile communication network further includes: first, caching the second information;
随后，在反馈信息指示用户成功接收第一信息时，或缓存第二信息的时间超过第一预设时间时，清除第二信息。Subsequently, when the feedback information indicates that the user has successfully received the first information, or when the time for caching the second information exceeds a first preset time, the second information is cleared.
具体地，当移动通信网络中的第二PDCP实体从上层收到第二信息后，首先将缓存第二信息；随后，在反馈信息指示用户成功接收第一信息时，清除第二信息，也就是说，移动通信网络中的第二PDCP实体通过反馈信息中的接收状态确认用户的PDCP实体已经成功收到第一信息时，第二PDCP实体将丢弃缓存的第二信息，即PDCP SDU以及其所对应的PDCPData PDU。Specifically, when the second PDCP entity in the mobile communication network receives the second information from the upper layer, it will first cache the second information; then, when the feedback information indicates that the user has successfully received the first information, the second information will be cleared. That is to say, when the second PDCP entity in the mobile communication network confirms through the receiving status in the feedback information that the user's PDCP entity has successfully received the first information, the second PDCP entity will discard the cached second information, i.e., the PDCP SDU and its corresponding PDCPData PDU.
或者，在缓存第二信息的时间超过第一预设时间时，清除第二信息，也就是说，移动通信网络中的第二PDCP实体配置了discardTimer，那么在接收到第二信息后，启动对应的discardTimer，若该discardTimer超过第一预设时间，第二 PDCP实体将丢弃缓存的第二信息，即PDCP SDU以及其所对应的PDCP Data PDU。Alternatively, when the time for caching the second information exceeds the first preset time, the second information is cleared. That is to say, if the second PDCP entity in the mobile communication network is configured with a discardTimer, then after receiving the second information, the corresponding discardTimer is started. If the discardTimer exceeds the first preset time, the second PDCP entity will discard the cached second information, that is, the PDCP SDU and its corresponding PDCP Data PDU.
需要注意的是，如果相应的第二消息，即其中的PDCP Data PDU已经被移动通信网络的第二PDCP实体发送给下层，那么将生成丢弃指令并发送给下层。It should be noted that if the corresponding second message, ie the PDCP Data PDU therein, has been sent to the lower layer by the second PDCP entity of the mobile communication network, then a discard instruction will be generated and sent to the lower layer.
本发明的一种实施方式中，移动通信网络对第二信息的处理过程还包括：首先，缓存第二信息；In one embodiment of the present invention, the processing of the second information by the mobile communication network further includes: first, caching the second information;
随后，根据一组第二信息生成对应的一组喷泉码，并清除一组第二信息；Subsequently, a corresponding set of fountain codes is generated according to the set of second information, and the set of second information is cleared;
并在反馈信息指示用户成功接收一组第二信息所对应的一组第一信息时，或缓存一组喷泉码的时间超过第二预设时间时，清除一组喷泉码。When the feedback information indicates that the user has successfully received a set of first information corresponding to a set of second information, or when the time for caching a set of fountain codes exceeds a second preset time, a set of fountain codes is cleared.
具体地，对移动通信网络中的第二PDCP实体从上层收到的一个或多个第二信息，即一个或多个PDCP SDU和/或其所对应的PDCP PDU，首先将缓存第二信息，随后采用特定的计算方式，对这组第二信息生成对应的一组喷泉码。此处的喷泉码可为LT码、或Raptor码、或在线码等。Specifically, for one or more second information, i.e., one or more PDCP SDUs and/or PDCP PDUs corresponding thereto, received by a second PDCP entity in a mobile communication network from an upper layer, the second information is first cached, and then a corresponding set of fountain codes is generated for the set of second information using a specific calculation method. The fountain code here may be an LT code, a Raptor code, an online code, or the like.
随后，根据这一组第二信息生成对应的这组喷泉码，并清除这组第二信息，也就是说，在计算得出喷泉码后，立刻将一个或多个PDCP SDU和/或其所对应的PDCP PDU进行丢弃。Subsequently, the corresponding set of fountain codes is generated according to the set of second information, and the set of second information is cleared, that is, after the fountain code is calculated, one or more PDCP SDUs and/or their corresponding PDCP PDUs are immediately discarded.
最后，在反馈信息指示用户成功接收这组第二信息所对应的一组第一信息时，清除这组喷泉码，即移动通信网络中的第二PDCP实体通过反馈信息中的接收状态确认用户的PDCP实体已经成功收到第一信息时，第二PDCP实体将丢弃这组喷泉码；或者，当缓存这组喷泉码的时间超过第二预设时间时，清除这组喷泉码，即移动通信网络中的第二PDCP实体为生成的喷泉码配置discardTimer2，在生成喷泉码后启动对应的discardTimer2，若该discardTimer2超过第二预设时间，第二PDCP实体将丢弃这组喷泉码。Finally, when the feedback information indicates that the user has successfully received a group of first information corresponding to the group of second information, the group of fountain codes is cleared, that is, when the second PDCP entity in the mobile communication network confirms through the receiving status in the feedback information that the user's PDCP entity has successfully received the first information, the second PDCP entity will discard the group of fountain codes; or, when the cache time of this group of fountain codes exceeds the second preset time, the group of fountain codes is cleared, that is, the second PDCP entity in the mobile communication network configures discardTimer2 for the generated fountain code, and starts the corresponding discardTimer2 after the fountain code is generated. If the discardTimer2 exceeds the second preset time, the second PDCP entity will discard the group of fountain codes.
本发明的一种实施方式中，移动通信网络传输第二信息的处理过程还包括：In one embodiment of the present invention, the process of transmitting the second information through the mobile communication network further includes:
在反馈消息指示用户未成功接收第一信息时，When the feedback message indicates that the user has not successfully received the first information,
确定对应于第一信息的第一PDCP序列号的第二PDCP序列号；Determine a second PDCP sequence number corresponding to the first PDCP sequence number of the first information;
将包含第二PDCP序列号的第二信息传输至用户。The second information including the second PDCP sequence number is transmitted to the user.
具体地，用户接收信息的PDCP实体，根据对第一信息的接收状态，生成反馈信息，反馈信息可以为PDCP status report，也可以为一种新的反馈信息。并通过用户与移动通信网络中的移动通信基站之间的上行链路发送给移动通信基站。移动通信基站中的第二PDCP实体收到反馈信息之后，将在根据反馈信息所指示的第一信息的接收状态得出用户未成功接收第一信息时，第二PDCP实体将根据对两个PDCP序列号进行编号的映射方式以及两个方式之间的对应关系，在第二 PDCP实体缓存的所有信息中，确定对应于第一信息的第一PDCP序列号的第二 PDCP序列号，并将包含第二PDCP序列号的第二信息发送给用户，以完成用户初次对广播网络下发的第一信息接收失败时，再次接收移动通信网络下发的对应信息的目的，进而提升广播网络的信息传输质量。Specifically, the PDCP entity that receives the information from the user generates feedback information based on the reception status of the first information. The feedback information can be a PDCP status report or a new feedback information. And it is sent to the mobile communication base station through the uplink between the user and the mobile communication base station in the mobile communication network. After the second PDCP entity in the mobile communication base station receives the feedback information, when it is concluded that the user has not successfully received the first information based on the reception status of the first information indicated by the feedback information, the second PDCP entity will determine the second PDCP sequence number corresponding to the first PDCP sequence number of the first information from all the information cached by the second PDCP entity based on the mapping method for numbering the two PDCP sequence numbers and the correspondence between the two methods, and send the second information containing the second PDCP sequence number to the user, so as to complete the purpose of receiving the corresponding information sent by the mobile communication network again when the user fails to receive the first information sent by the broadcast network for the first time, thereby improving the information transmission quality of the broadcast network.
此处需要说明的是，反馈消息所指示的用户未成功接收第一信息状态包括：广播网络未发送第一信息或发送的第一信息错误、信道传输过程中第一信息出现丢包等情况、用户成功接收第一信息但未成功解码等。It should be noted here that the status of the user's failure to successfully receive the first information indicated by the feedback message includes: the broadcast network failed to send the first information or sent the first information incorrectly, the first information was lost during channel transmission, the user successfully received the first information but failed to decode it successfully, etc.
本发明的一种实施方式中，移动通信网络传输第二信息的处理过程还包括：In one embodiment of the present invention, the process of transmitting the second information through the mobile communication network further includes:
在反馈消息指示用户未成功接收第一信息时，When the feedback message indicates that the user has not successfully received the first information,
首先，确定对应于第一信息的第一PDCP序列号的第二PDCP序列号；First, determining a second PDCP sequence number corresponding to the first PDCP sequence number of the first information;
随后，确定第二PDCP序列号所对应的第二信息所在的一组第二信息；Subsequently, determining a group of second information to which the second information corresponding to the second PDCP sequence number belongs;
最后，将这组第二信息所对应的一组喷泉码中的一个或多个喷泉码传输至用户。Finally, one or more fountain codes in a group of fountain codes corresponding to the group of second information are transmitted to the user.
具体地，用户的反馈信息的接收状态得出用户未成功接收第一信息时，第二 PDCP实体将根据对两个PDCP序列号进行编号的映射方式以及两个方式之间的对应关系，在第二PDCP实体缓存的所有信息中，首先确定对应于第一信息的第一PDCP序列号的第二PDCP序列号，随后，确定第二PDCP序列号所对应的第二信息所在的一组第二信息，这组第二信息可以包括一个或多个第二信息，最后将这组第二信息所对应的一组喷泉码传输至用户，这组喷泉码可以包括一个或多个喷泉码，相应地，用户接收到喷泉码后，将通过对应的解码方式得到对应于广播网络下发的第一信息的第二信息，以完成用户初次对广播网络下发的第一信息接收失败时，再次接收移动通信网络下发的对应信息的目的，进而提升广播网络的信息传输质量。Specifically, when the reception status of the user's feedback information indicates that the user has not successfully received the first information, the second PDCP entity will, based on the mapping method for numbering the two PDCP sequence numbers and the correspondence between the two methods, first determine the second PDCP sequence number corresponding to the first PDCP sequence number of the first information among all the information cached by the second PDCP entity, and then determine a group of second information including the second information corresponding to the second PDCP sequence number, which may include one or more second information. Finally, a group of fountain codes corresponding to the group of second information is transmitted to the user, which may include one or more fountain codes. Accordingly, after receiving the fountain code, the user will obtain the second information corresponding to the first information sent by the broadcast network through the corresponding decoding method, so as to complete the purpose of receiving the corresponding information sent by the mobile communication network again when the user fails to receive the first information sent by the broadcast network for the first time, thereby improving the information transmission quality of the broadcast network.
如图3所示，本发明还提供一种移动通信网络辅助广播网络的接收方法，用户接收广播网络下发的第一信息；As shown in FIG3 , the present invention also provides a method for receiving a mobile communication network assisted by a broadcast network, wherein a user receives first information sent by the broadcast network;

第一信息的第一序列号与第二信息的第二序列号呈对应关系。The first serial number of the first information corresponds to the second serial number of the second information.
如图2所示，还提供一种移动通信网络辅助广播网络的传输系统，包括：As shown in FIG2 , a transmission system of a mobile communication network assisting a broadcast network is also provided, including:

具体地，本发明考虑到广播网络的单向性，无法在用户未成功接收到广播网络下发的信息时进行及时调整，本发明基于移动通信网络的双向性，提供一种移动通信网络辅助广播网络的传输系统，其中的广播网络用于发送第一信息至用户，以及向移动通信网络发送对应于第一信息的第二信息，而移动通信网络用于接收用户上传的反馈信息，并根据反馈信息指示的用户对第一信息的接收状态，将对应的第二信息传输至用户，使在用户未成功接收广播网络下发的第一信息时，接收到移动通信网络从广播网络收到的对应于第一信息的第二信息，实现信息的正确传输，由此可见本发明提供的移动通信网络辅助广播网络的传输系统，通过移动通信网络的双向传输，及时获取用户对于广播业务的接收状态，并可以向用户进行补包重传，提高广播网络业务中传输质量，提升广播网络系统性能。需要注意的是，广播网络将第一信息发送给用户，以及广播网络向移动通信网络发送第二信息这两个步骤之间不存在特定的先后顺序。Specifically, the present invention takes into account the unidirectionality of the broadcast network and cannot make timely adjustments when the user fails to successfully receive the information sent by the broadcast network. Based on the bidirectionality of the mobile communication network, the present invention provides a transmission system of a mobile communication network assisting a broadcast network, wherein the broadcast network is used to send a first message to the user, and to send a second message corresponding to the first message to the mobile communication network, and the mobile communication network is used to receive feedback information uploaded by the user, and transmit the corresponding second information to the user according to the user's reception status of the first information indicated by the feedback information, so that when the user fails to successfully receive the first information sent by the broadcast network, the second information corresponding to the first information received by the mobile communication network from the broadcast network is received, and the correct transmission of the information is achieved. It can be seen that the transmission system of the mobile communication network assisting the broadcast network provided by the present invention can obtain the user's reception status of the broadcast service in a timely manner through the bidirectional transmission of the mobile communication network, and can perform packet supplementation and retransmission to the user, thereby improving the transmission quality in the broadcast network service and improving the performance of the broadcast network system. It should be noted that there is no specific order between the two steps of the broadcast network sending the first information to the user and the broadcast network sending the second information to the mobile communication network.
