上述所有可选技术方案，均可按照任意结合形成本发明的可选实施例，在此不再一一赘述。
在实际场景中，指定通信服务系统可以是指一个包含了多个不同功能平台的服务器集群，参见图3，该指定通信服务系统可以包括诸如用于提供信令接入服务的接入平台、用于提供消息与状态服务的消息平台、用于提供富媒体策略服务的富媒体平台、用于提供富媒体数据服务的基础架构平台、用于提供音视频策略服务和音视频数据服务的音视频平台和用于提供身份校验服务的资料关系链平台等等，客户端通过信令通道与服务端的各个不同服务器之间进行数据和信令的交互。
为了便于理解，下面针对各个平台以及平台之间的交互进行介绍：
(1)接入平台，用于信令接入服务。该接入平台的具体功能包含外网接入调度、消息/信令分发、数据加密等。
(2)消息平台，用于提供消息与状态服务。该消息平台的具体功能包括提供用户实例注册与在线状态管理、消息过滤与转发、协议转换、链路加密、鉴权、用户身份校验收敛等，是基础即时通讯能力的关键服务。
(3)富媒体平台，用于提供富媒体策略服务。该富媒体平台的具体功能包括提供与富媒体策略相关的后台接口，如秒传、获取上传/下载地址的接口等。
(4)基础架构平台，用于提供富媒体数据服务。该基础架构平台的具体功能包括提供数据存储与接入相关的后台接口，如数据上传/下载接 入、存储、索引等。
(5)音视频平台，用于提供音视频策略服务和音视频数据服务。该音视频平台的具体功能包括提供与音视频策略相关的后台接口，如创建房间、查询房间信息等，还包括提供音视频数据中转与流量控制相关的后台接口等。
(6)资料关系链平台，用于提供身份校验服务。该资料关系链平台的具体功能包括提供外部账号与通信体系内部账号的互转、各类账号的身份校验接口等。
基于上述图3中的系统架构，图4是本发明实施例所示的一种提供指定通信服务的方法的流程图。参见图4，该实施例具体包括：
401、第三方应用客户端向信令接入服务器发送指定通信服务请求，该指定服务请求携带本端的第三方应用标识和第一用户身份标识，该信令接入服务器用于提供指定通信的接入服务。
该第一用户可以是终端上任一第三方应用客户端的用户，该应用预先在信令接入服务器的服务提供商处注册了指定通信服务，因此，当第一用户需要在该第三方应用客户端上使用指定通信服务时，可以触发指定通信服务请求，并将该指定通信服务请求发送至信令接入服务器，该指定通信服务可以是音视频服务、消息服务或富媒体服务等，本发明实施例对此不作限定，在发送指定通信服务请求时，该指定通信服务请求可以携带该指定通信服务标识，如，当该指定通信服务为音视频服务时，该指定通信服务请求可以携带音视频服务标识，而当该指定通信服务请求为富媒体服务时，该指定通信服务请求可以携带富媒体服务标识。
需要说明的是，该应用客户端的开发商预先可以对该客户端进行注册，以使得该应用客户端能够使用本发明实施例中所提供的指定通信服务。
参见图5，该注册过程可以有如下步骤：
第一步，为申请接入的应用进行注册。
需要使用指定通信服务的应用开发商可以向指定通信服务系统(即服务提供商)注册开发者账号。该注册过程可以是应用开发商向信令接入服务器发送注册请求，由信令接入服务器根据注册请求所携带的应用标识以及目标接入服务等信息，对应用开发商进行审核。在实施中，应用开发商可以在请求注册阶段进行付费，由服务提供商确认付费成功后，为该应用开发商的应用进行注册，当然，该付费过程可以是线上进行或线下进行，本发明实施例对此不做限定。
需要说明的是，上述注册请求携带应用标识以及目标接入服务的同时，还可以携带应用的其他基本信息，如应用编号、应用接入所需信息等等，这些信息还可以是在实际的注册阶段由应用开发商提供，本发明实施例对此不作限定。
对于一个应用开发商来说，可以注册开发者账号，以使得该应用开发商能够基于该开发者账号，录入应用相关信息，以便该应用开发商所录入的应用客户端使用由指定通信服务系统提供的指定通信服务。
第二步，指定通信服务系统为注册成功的应用颁发应用标识和应用校验数据，该应用标识用于唯一标识该应用，该应用校验数据用于对该应用的合法性进行校验。
当服务提供商管理员对该应用的注册审批通过后，可以为注册成功的应用颁发用于唯一标识该应用的应用标识(Appid)，并为该应用颁发应用校验数据(Appkey)，其中，该应用校验数据可以根据该应用的基本信息生成，该生成过程可以应用预设加密算法进行，在此不做赘述。终端可以在安装该应用时，获取到该应用标识和应用校验数据，以便后续在应用运行过程中，可以基于该应用标识和应用校验数据向指定通信服务系统请求指定通信服务。
上述注册可以基于实施例中所提供的OAUTH协议，使得在后续应用用户使用指定通信服务系统提供的指定通信服务时，OAUTH的授权不会使信令接入服务器触及到用户的帐号信息(如用户名与密码)，即指定通信服务系统无需使用用户的用户名与密码就可以申请获得该用户资源的授权，其保密性较 好、安全性较高。
402、信令接入服务器在接收到终端的指定通信服务请求时，将该指定通信服务请求发送至资料关系链平台。
403、资料关系链平台对该应用标识和该第一用户身份标识进行验证，并向信令接入服务器返回验证结果。
该验证过程可以看做是对信令通道的初始化过程，在该验证过程中，资料关系链平台根据接收到的指定通信服务请求中所携带的应用标识和第一用户身份标识进行验证，当验证通过时，可以为该第一用户提供如音视频服务等指定通信服务。
404、如果该应用标识和第一用户身份标识验证通过，信令接入服务器与该第三方客户端建立信令通道，所述信令通道用于提供信令传输接口。
其中，该第三方客户端内可以提供指定通信服务SDK，如音视频SDK，其中封装有信令接入服务器地址以及指定通信服务所必须的功能接口，供客户端业务侧使用。该信令通道可以由信令SDK建立，该信令SDK封装了信令接入服务器地址以及指定通信服务SDK与后台之间的通讯接口、提供外部账号与通信体系内部账号之间的转换接口。该信令通道的建立可以包括指定通信服务SDK和信令SDK与信令接入服务器的多次数据交互，本发明实施例对此不作赘述。
405、信令接入服务器还用于基于所述信令通道，通过消息平台、音视频平台和富媒体平台中至少一个平台为所述第三方应用客户端提供指定通信服务。
该信令接入服务器可以基于信令通道和多种指定通信平台为第三方应用客户端提供指定通信服务，包括消息服务、音视频服务以及富媒体服务等。
406、如果信令接入服务器接收到该第一用户的结束音视频服务请求，指定通信服务系统销毁该信令通道。
当会话结束时，信令接入服务器销毁该信令通道，也即是销毁为提供指定 通信服务而创建后台在线实例。
当信令接入服务器与终端之间建立该信令通道时，在指定通信服务侧为该第一用户创建一在线实例，基于该在线实例，为第一用户提供指定通信服务，下面分别以音视频服务、消息服务以及富媒体服务等不同的指定通信服务流程为例，对各个流程进行详细介绍：
对于音视频服务来说，在提供音视频通信服务的过程中，终端和指定通信服务系统之间的交互可以包括下述步骤A1-A4：
A1、终端通过该信令通道向该信令接入服务器发送音视频房间创建请求。
当第一用户想要进行音视频通信时，可以在终端上进行操作，以触发音视频房间创建请求。
A2、信令接入服务器接收到音视频房间创建请求时，将音视频房间创建请求发送至音视频平台，由音视频平台为第一用户分配音视频数据服务地址。
A3、音视频平台基于所述音视频数据服务地址，创建音视频房间。
需要说明的是，音视频平台在创建音视频房间时，可以基于音视频策略服务进行。如，可以根据用户级别等不同用户属性，为不同的用户创建不同的房间，如房间容纳人数不同、房间中可分享数据类型不同等等，用户级别高的用户所创建房间的容纳人数可以大于用户级别低的用户所创建房间的容纳人数。当然，具体是否根据用户属性进行区分或者如何进行区分，可以根据该应用与指定通信服务系统在注册过程中的协商确定，本发明实施例对此不作赘述。
A4、音视频平台基于所述音视频房间，为第一用户提供音视频通信服务。
具体地，在音视频房间创建成功后，第一用户可以通过所述信令通道向所述信令接入服务器发送第二用户标识和音视频房间标识，使得所述信令接入服务器通过消息平台向所述第二用户发送邀请消息，当所述第二用户接受邀请时进入所述音视频房间；所述第一用户向所述音视频数据地址发送音视频数据，使得音视频平台将所述音视频数据发送至所述音视频房间内的第二用户。
当音视频平台对音视频房间创建成功时，可以将该音视频房间标识发送至 第一用户，使得第一用户通过业务后台或消息平台邀请第二用户进入音视频房间，第一用户以及第一用户所邀请的第二用户可以通过该音视频数据服务地址，进行后续的音视频通话，由音视频平台对用户之间的通话数据进行实时转发。
当第二用户接收到来自发起者的邀请消息之后，向音视频平台请求加入音视频房间(即加入此次音视频会话)，加入成功后，会从音视频平台所提供的音视频策略服务中得到音视频数据服务地址，随后第二用户即可加入音视频房间，并与房间内的其他用户进行实时的音视频交流。
所邀请的第二用户可以是第一用户的用户关系链上的用户，也可以是与第一用户不存在任何用户关系的用户。该邀请可以通过输入用户标识、用户名称或用户群组标识，甚至输入电话号码等形式进行，也即是，终端在获取第二用户时，可以获取第一用户在终端上输入的用户标识、用户名称或用户群组标识等。对于不同类型的客户端，在获取第二用户时，可以有不同的获取对象。如，对于即时通信类的客户端，其获取对象可以是用户标识等，对于如信息分享平台类的客户端，其获取对象可以为用户群组标识等。
进一步地，第一用户可以对创建的音视频房间进行解散等处理，用户均可以根据自身的需要退出或再次加入音视频房间，当音视频平台检测到当前音视频房间内所有用户均已经退出房间时，销毁该音视频房间。可选地，在上述情况下，音视频平台可以通过信令接入平台向曾经加入过该音视频房间的第一用户和第二用户发送房间解散通知，并在发送通知后，对音视频房间进行销毁处理，以避免对音视频平台中音视频数据服务的空间的过度占用。
当然，在音视频房间销毁后，也可以对之前创建的在线实例进行销毁。该在线实例的销毁可以是在音视频房间销毁后，在预设时长内没有接收到第一用户的其他请求时进行。该预设时长可以由注册应用和指定通信服务系统之间约定，本发明实施例对此不作限定。
对于消息收发来说，在提供音视频通信服务的过程中，终端和指定通信服 务系统之间的交互可以包括下述步骤B1-B5：
B1、第一用户向信令接入服务器发送消息发送请求，该消息发送请求携带消息内容和目标用户。
第一用户可以向其他用户发送消息，当然，其发送对象也可以是第一用户所选中的任一用户，该任一用户可以是与第一用户在同一账号机制下的用户，也可以是由指定通信服务系统提供服务的用户。
B2、信令接入服务器将该消息发送请求发送至消息平台。
B3、消息平台根据第一用户的消息发送请求携带的目标用户，查找目标用户的在线实例。
B4、如果找到该目标用户的在线实例，消息平台向目标用户发送该消息内容。
B5、如果未找到该目标用户的在线实例，消息平台缓存该消息内容，直到该目标用户来注册在线实例，向该目标用户发送该消息内容。
在上述步骤B2-B5中，对于消息平台来说，如果该目标用户也由指定通信服务系统提供服务，并在消息平台上注册有在线实例，则可以实时将消息内容转发至该目标用户，而如果当前该目标用户并没有使用指定通信服务系统的服务，如处于离线状态等，则可以缓存消息内容，在后续该目标用户来注册后，再进行消息的转发。该过程也可以是基于目标用户在消息平台上注册时所使用的联系信息进行，如，目标用户设置了离线消息提醒或是消息转发机制，还可以由消息平台根据其设置的具体机制，采用与其联系信息对应的联系方式，进行提示。如，目标用户设置了邮件提醒，则可以将该消息内容或用于提示消息内容的提示信息发送至目标用户设置的电子邮箱中。
对于富媒体服务来说，在提供富媒体服务的过程中，终端和指定通信服务系统之间的交互可以包括下述步骤C1-C5：
C1、终端通过该信令通道向该信令接入服务器发送富媒体上传请求。
C2、信令接入服务器将富媒体上传请求发送至资料关系链平台，由资料关 系链平台对该数据传输请求进行验证。
该富媒体上传请求可以携带应用标识和第一用户身份标识，以便资料关系链平台对其进行验证，当验证通过时，为该第一用户提供富媒体服务。
C3、当资料关系链平台对所述富媒体上传请求验证通过时，由富媒体平台为第一用户分配富媒体数据服务地址和富媒体文件标识。
富媒体数据服务地址是指用于存储富媒体数据的存储空间地址，该数据传输请求还可以携带数据大小等相关信息，以使得富媒体平台为该数据分配相应的存储空间，为了便于后续对存储数据的查询等操作，富媒体平台还为该富媒体数据分配文件标识。
C4、富媒体平台接收所述第一用户上传至所述富媒体数据服务地址的富媒体文件。
C5、当接收到第二用户发送的下载请求，富媒体平台根据所述下载请求携带的富媒体文件标识，向所述第二用户发送所述富媒体数据服务地址，使得所述第二用户下载所述富媒体文件。
第一用户可以将该富媒体文件标识发送给第二用户，使得第二用户基于该富媒体文件标识从富媒体平台上进行富媒体文件的下载，该下载的具体过程可以是第二用户向富媒体平台发送携带富媒体文件标识的下载请求，当富媒体平台可以根据该富媒体文件标识，向第二用户发送对应的富媒体数据服务地址，从而使得第二用户从该富媒体数据服务地址中下载富媒体文件。
需要说明的是，上述消息服务和音视频服务以及多媒体数据服务均可以是在同一个服务过程中并存，如在指定通信服务系统在为第一用户提供音视频服务时，还可以为第一用户提供消息服务和多媒体数据服务中的至少一种，以通过整个指定通信服务系统中的多个平台为该第三方应用客户端提供至少两种指定通信服务，使得客户端用户在使用音视频服务或多媒体数据服务时，仍可以通过文本等消息服务，进行消息交互，从而提高了指定通信服务的灵活性。
针对目前音视频即时通讯领域研发门槛和运营维护成本较高，中小应用开 发商虽有很强的需求却受限于自身研发和运营能力而无法独立提供服务等问题，提出了一种高质量、低成本、接入灵活、使用方便、产品覆盖领域广泛的开放的音视频即时通讯系统解决方案。利用本发明提出的技术解决方案，应用开发商可以不必关注后端服务的运营部署，而只需将精力集中在其擅长的领域，以极小的开发代价、低廉的运营成本即可享受到高品质的实时音视频即时通讯服务，从而更容易快速打造出自己的精品应用、迅速占领市场。
本发明实施例所示的方法，通过基于第三方应用客户端的请求，在第三方应用客户端与能够指定通信服务系统之间建立信令通道，为第三方应用提供了接入指定通信服务的基础，能够为不具备音指定通信能力的应用提供了相对独立的指定通信服务，提高了应用的使用灵活性，降低了应用开发商在指定通信服务时所需的运营成本以及开发成本。
