支持异构终端通过云平台接入的会议系统及接入方法Conference system and access method supporting heterogeneous terminal access through cloud platform

技术领域technical field

本发明涉及一种支持异构终端通过云平台接入的会议系统及接入方法。The present invention relates to a conference system and an access method for supporting heterogeneous terminals to access through a cloud platform.

背景技术Background technique

随着宽带的普及和市场对移动办公需求的不断增长，对于会议系统的需求亦随之大幅增加。With the popularity of broadband and the growing demand for mobile office, the demand for conference systems has also increased significantly.

值得注意的是，专用会议系统存在价格昂贵的问题，故中小企业通常不会购置该类系统，并倾向以市面上现有的通讯软件实现一对一或多方参与的虚拟会议；然而，现有的通讯软件通常存在通讯延迟、低清晰度等明显不利于会议进行的干扰因素，难以获得良好的使用者体验，同时，现有不同种类通讯软件之间无法进行音频或视频的实时交互通讯，例如微信帐号与QQ帐号之间无法实现实时通讯。It is worth noting that dedicated conference systems are expensive, so small and medium-sized enterprises usually do not purchase such systems, and tend to use the existing communication software on the market to realize one-to-one or multi-party virtual conferences; however, existing The communication software usually has communication delay, low definition and other interference factors that are obviously unfavorable to the conference, and it is difficult to obtain a good user experience. Real-time communication is not possible between WeChat accounts and QQ accounts.

反观大企业和政府单位则倾向于购置价格高昂、专业的会议系统(VMR)，以实现通讯低延迟、高清晰度的良好使用者体验；然而，专用会议系统仅支持专用软件、硬件终端及PSTN电话，换言之，在企业或政府单位之外的会议参与者只要不具备前述终端即无法参与该虚拟会议，造成实际使用上的不便，同时，现有不同种类的专用软件、硬件终端之间也同样无法进行音频或视频的实时交互通讯。且专用会议系统硬件设备不仅价格高昂，购置后更需要企业配置专人进行系统维护管理或协助访问操作，也无法依企业需求快速增加新的会议桥。On the other hand, large enterprises and government units tend to purchase expensive and professional conference systems (VMR) to achieve a good user experience with low communication delay and high definition; however, dedicated conference systems only support dedicated software, hardware terminals and PSTN Telephone, in other words, conference participants outside the enterprise or government unit cannot participate in the virtual conference as long as they do not have the aforementioned terminals, causing inconvenience in actual use. Real-time interactive communication with audio or video is not possible. Moreover, the dedicated conference system hardware equipment is not only expensive, but also requires the enterprise to configure special personnel for system maintenance and management or assist in access operations after purchase, and it is impossible to quickly add new conference bridges according to the needs of the enterprise.

所以，现有通讯软件及专用会议系统在使用上存在原有会议系统难以接入与其他会议系统及/或通讯软件进行整合的技术问题，例如：Therefore, there are technical problems in the use of existing communication software and dedicated conference systems that the original conference system is difficult to access and integrate with other conference systems and/or communication software, such as:

(1)当企业内部原有的会议系统处于仍可使用，但存在部分使用问题而需要引入新的会议系统时，新、旧系统之间无法兼容并用。(1) When the original conference system in the enterprise is still available, but there are some problems in use and a new conference system needs to be introduced, the new and old systems cannot be used together.

(2)企业已有惯用的会议系统，但多数对外会议的参与者只有通讯软件能够使用时，则难以有效使用原有的会议系统，且对外会议的使用者体验相当受到限制。(2) The enterprise already has a conventional conference system, but when most of the participants of the external conference only have communication software to use, it is difficult to use the original conference system effectively, and the user experience of the external conference is quite limited.

(3)快速发展的集团公司内部没有做好信息技术统一规划，各子公司内部分别采用了不同的会议系统，导致会议系统之间整合困难且成本高昂。(3) The fast-growing group company has not made a unified plan for information technology, and each subsidiary has adopted different conference systems, which makes the integration of conference systems difficult and costly.

对于会议系统参与人数的限制，现有通讯软件及专用会议系统都有上限限制，从而存在原有会议系统的接入容量不易扩大或加强的技术问题，例如：For the limitation of the number of participants in the conference system, the existing communication software and the dedicated conference system have upper limits, so there are technical problems that the access capacity of the original conference system is not easy to expand or strengthen, such as:

(1)原有会议系统的参与人数接入容量有时会不敷使用，向会议系统服务厂商购买接入容量更高的帐号，导致固定支出的成本增加，但高接入容量的帐号未能有效被使用的状况。(1) The access capacity of the number of participants in the original conference system is sometimes insufficient. Purchase an account with a higher access capacity from the conference system service manufacturer, resulting in an increase in the cost of fixed expenses, but the account with high access capacity is not valid. status of being used.

(2)企业扩张后需要更接入容量更大的会议系统，但原为小型企业时采用的如钉钉等现有通讯软件已形成企业内部惯用的会议通讯方式，两者难以无法兼容并用。(2) After the enterprise expands, it needs to connect to a conference system with a larger capacity, but the existing communication software such as DingTalk used in the original small enterprise has formed the usual conference communication method within the enterprise, and it is difficult for the two to be compatible and used together.

对于跨团队/公司的虚拟会议，容易发生参与团队/公司之间的会议系统不同而无法实现高效率会议的使用需求。对于跨国虚拟会议，通过电话接入现有专用会议系统存在国际长途电话太贵的问题，而通过Internet接入专用会议系统则容易因国际出口带宽窄导致音质差的状况，难以保障良好的使用者体验。For cross-team/company virtual meetings, it is easy to encounter different meeting systems between participating teams/companies, and the use of high-efficiency meetings cannot be achieved. For transnational virtual conferences, accessing the existing dedicated conference system by telephone is too expensive for international long-distance calls, while accessing the dedicated conference system through the Internet is prone to poor sound quality due to the narrow international egress bandwidth, making it difficult to ensure good users. experience.

此外，由于现有通讯软件及会议系统只能与相同的软件终端或硬件终端进行通讯，使参与者之间能够获得彼此的身份信息或者私下加好友，从而不符合部分工作具有中介性质的会议发起者的使用需求。In addition, because the existing communication software and conference system can only communicate with the same software terminal or hardware terminal, so that participants can obtain each other's identity information or add friends privately, which does not meet the initiation of conferences with intermediary nature of some work. users' needs.

综上，现有的通讯软件及专用会议系统的软件终端或硬件终端，确实不符合实际使用需求，有待进一步开发及改进。To sum up, the existing communication software and the software terminal or hardware terminal of the dedicated conference system do not meet the actual use requirements and need to be further developed and improved.

The terminal sends an account login request. If the initiator logs in to the account, the cloud platform binds the initiator account with the heterogeneous terminal that initiated the conference, generates a new heterogeneous terminal number after the binding is completed, and imports the usage record of the account to The conference initiates a heterogeneous terminal; if the initiator does not have an account, the cloud platform controls the terminal layer to send an account registration request to the conference initiating heterogeneous terminal through the middle layer, and sends an account registration request for the conference when the initiator completes the registration Initiate a heterogeneous terminal to generate a new heterogeneous terminal number;

Sending an account login request, if the initiator logs in to the account, the cloud platform detects whether the initiator account and the heterogeneous terminal number are bound. The use record of the organization terminal determines the meeting preference of the initiator. If there is no binding relationship between the initiator's account and the heterogeneous terminal number, the cloud platform determines that the initiator uses the unbound heterogeneous terminal to send a meeting application and records the meeting according to the initiator's account. Determine the conference preference of the initiator; if the initiator does not have an account, the cloud platform sends an account registration request to the heterogeneous terminal through the middle layer control terminal layer, and when the initiator completes the registration, the registered account is registered with the conference initiating heterogeneous terminal to bind.
