Description

一种会话方法、 系统及装置 本申请要求于 2008 年 4 月 23 日提交中国专利局、 申请号为 200810093945.7、 发明名称为 "一种会话方法、 系统及装置" 的中国 专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明实施例涉及通信技术领域， 特别是涉及一种会话方法、 系 统及装置。 背景技术
PoC ( Push to talk over Cellular, 无线一键通）即基于无线移动网 络的 "即按即讲" 业务， 是一种允许用户通过手机终端的特定按键进 行立即通信的半双工语音业务。 PoC是基于 VoIP ( Voice over IP, 基 于 IP网络的语音传输）技术的通信业务。 VoIP与传统的 PSTN( Public Switched Telephone Network,公共交换电话网 )电话采用的技术不同， 是一种利用 IP ( Internet Protocol, 网际协议） 网络和 IP协议 载语 音的通信方式。 PoC的本质是采用分组交换技术， 在蜂窝网上实现了 实时集群对讲功能。
现有的 PoC会话的建立过程， 通过 PoC Server检查被叫用户是 否已经上线， 如果用户上线则向核心网发送 SIP Invite请求， 邀请被 叫进入会话， 如果用户不上线， 则 PoC Server给主叫用户发送 4xx 响应， 放弃会话。 发明内容
本发明实施例提供一种会话方法、 系统及装置， 以实现用户离线 时保证用户获取离线时的呼叫情况， 提高用户的业务体验。
为达上述目的， 本发明实施例提供一种会话方法， 包括： 接收处于会话中的主叫用户邀请被叫用户加入所述会话的呼叫 请求；
根据所述呼叫请求检测所述被叫用户是否在线， 当检测到所述被 叫用户离线时， 记录所述邀请被叫用户加入所述会话的离线呼叫信 息；
当所述被叫用户上线时，检测所述离线呼叫信息中的所述会话是 否终止， 如果未终止， 则将所述被叫用户加入所述会话中。
本发明实施例还提供一种会话服务器， 包括：
接收模块，用于接收处于会话中的主叫用户邀请被叫用户加入所 述会话的呼叫请求；
第一检测模块， 用于检测所述被叫用户是否上线；
记录触发模块，用于在所述第一检测模块检测到所述被叫用户离 线时触发记录网元记录所述邀请被叫用户加入所述会话的离线呼叫 信息；
第二检测模块，用于在所述第一检测模块检测到所述被叫用户上 线时进一步检测所述被叫用户的离线呼叫信息中的会话是否终止； 会话邀请模块，用于将所述第一检测模块检测到上线的被叫用户 加入到所述离线呼叫信息中所述第二检测模块检测到的未终止的会 话中。
本发明实施例还提供一种记录网元， 包括：
离线呼叫信息记录模块，用于记录被叫用户离线时主叫用户邀请 所述被叫用户加入会话的离线呼叫信息，以便于会话服务器在所述被 叫用户上线时， 检测所述离线呼叫信息中的所述会话是否终止， 如果 未终止， 则将所述被叫用户加入所述会话中。
本发明实施例还提供一种会话系统， 包括： 会话服务器、 以及记 录网元； 其中，
所述会话服务器，用于接收处于会话中的主叫用户邀请被叫用户 加入所述会话的呼叫请求，根据所述呼叫请求检测所述被叫用户是否 在线， 当所述被叫用户上线时， 触发所述记录网元记录所述邀请被叫 用户加入所述会话的离线呼叫信息，进一步检测所述离线呼叫信息中 的所述会话是否终止， 如果未终止， 则将所述检测到上线的被叫用户 加入所述会话中；
所述记录网元，用于记录所述邀请被叫用户加入所述会话的离线 呼叫信息。
与现有技术相比， 本发明实施例的技术方案具有以下优点： 通过提供一种记录网元，用户可以获知自己未上线时的被呼叫信 息， 可以告知服务器如何保存对自己的呼叫记录； 上线后， 服务器可 按照用户设定的策略， 自动邀请用户加入当前还存在的会话中。 通过 这种装置可以减少用户遗失重要会话信息的几率，并且能增强用户好 的使用体验。 附图说明
图 1为本发明实施例一中的一种会话方法流程图；
图 2为本发明实施例二中的一种会话方法流程图；
图 3为本发明实施例三中的一种会话系统架构示意图。 具体实施方式
下面结合附图和实施例， 对本发明的具体实施方式作进一步 详细描述：
本发明实施例一提供一种会话方法， 如图 1 所示， 包括以下 步骤：
步骤 S101 , 接收处于会话中的主叫用户邀请被叫用户加入会 话的呼叫请求。
步骤 S102, 根据呼叫请求检测被叫用户是否在线， 当检测到被 叫用户离线时， 记录邀请被叫用户加入会话的离线呼叫信息。
步骤 S103 , 当被叫用户上线时， 检测离线呼叫信息中的会话是 否终止， 如果未终止， 则将被叫用户加入会话中。 本实施例中， 在步骤 S103之前还包括：
被叫用户获取离线呼叫信息，根据离线呼叫信息设置并记录呼叫 策略； 当被叫用户上线且离线呼叫信息中的会话未终止时， 获取呼叫 策略， 根据呼叫策略将被叫用户加入与呼叫策略对应的会话中。
其中， 被叫用户获取离线呼叫信息包括： 被叫用户发送请求， 接 收该请求对应的离线呼叫信息；或者被叫用户即时或定期接收离线呼 叫信息， 实现该被叫用户在离线状态下也能获取离线呼叫信息。
例如：通过一个记录网元来记录邀请被叫用户加入会话的离线呼 叫信息， 则通过向记录网元发送请求， 记录网元 ^据该请求向被叫用 户发送离线呼叫信息；或者记录网元即时或定期自动向被叫用户发送 离线呼叫信息的方式使被叫用户获取离线时的所有离线呼叫信息，根 据离线呼叫信息设置呼叫策略， 设置呼叫策略包括： 根据离线呼叫信 息设置所有离线呼叫信息中的主叫用户的优先级别信息，会话发起时 间的优先级别信息， 黑名单信息， 以及并发邀请的主叫用户信息中的 一种或多种。 然后， 被叫用户向记录网元发送根据离线呼叫信息设置 的呼叫策略； 当该被叫用户上线且离线呼叫信息中的会话未终止时， 获取呼叫策略，根据设置的呼叫策略将被叫用户加入与所述呼叫策略 对应的会话中。 例如： 加入优先级别高（可以以主叫用户或会话的发 起时间为依据）的会话中， 或者同时加入多个并发的会话， 或者拒绝 当前还未结束的会话。
通常的呼叫策略是根据记录的离线呼叫信息制定的， 其中， 系统 也会保存一些被叫用户已知或预置的呼叫策略。 例如： 当被叫用户未 制定特定的呼叫策略时，按会话发起时间的优先级别信息将被叫用户 优先加入未终止的发起会话时间最早的会话中；或者并发邀请该被叫 用户加入多个当前未终止的会话， 被叫用户在并发的会话中， 也能根 据自己的意愿进行相应处理， 也可以动态调整呼叫策略。
本实施例中，为了释放存储空间以及及时地清理离线呼叫信息和 对应的呼叫策略，可以进一步设置所述离线呼叫信息及根据所述离线 呼叫信息设置的呼叫策略的保存时长； 在保存时长超时后， 删除所述 离线呼叫信息和所述呼叫策略，或者将所述离线呼叫信息和所述呼叫 策略设置为无效状态并保存日志数据。
本实施例中， 离线用户可获知自己离线时的被呼叫信息， 当用户 设置有呼叫策略时，根据呼叫策略将用户加入与所述呼叫策略对应的 会话， 并通过设置黑名单屏蔽一些用户拒绝的会话， 进一步增强了用 户体验。
本发明实施例二提供一种会话方法， 如图 2所示， 将实施例一 应用到具体的场景中， 以 PoC服务器为代表的会话服务器根据用 户设置的和呼叫策略建立会话， 记录网元为 InviteLogBox (邀请记 录网元）， 在被叫用户上线后， 对被叫用户主动进行呼叫。 会话流 程如下：
步骤 S201 , 用户 A发送 SIP Register请求给核心网， 注册上 线。
步骤 S202, 核心网返回 200 OK, 用户 A注册成功。
步骤 S203 , 核心网发送 SIP Register给 PoC Server, 通知用户 上线，
步骤 S204, PoC Server返回 200 OK。
步骤 S205 , 用户 Α发送 Invite请求给核心网， 邀请用户 B和 用户 C进行 PoC 会话。
步骤 S206, 核心网将请求转发给 PoC Server 0
步骤 S207, PoC Server发现用户 B没有上线， 于是发送被叫 记录保存请求通知 InviteLogBox保存被叫记录， InviteLogBox才艮 据用户 B的预先设置， 记录本次 PoC会话的发起人， 发起时间， 被叫人， 会话主题等等信息。
步骤 S208, PoC Server向核心网发送 Invite请求，邀请用户 C 力口入会话。
步骤 S209, 核心网将请求发送给用户 C。
步骤 S210, 用户 C接受请求， 返回 200 OK, 加入会话。 步骤 S211 , 核心网发送用户 C的 200 OK给 PoC Server。 步骤 S212 PoC Server发送 200 OK给核心网。
步骤 S213 核心网将 200 OK发送给用户 A。
步骤 S214 用户 A返回 ACK确认响应给核心网。
步骤 S215 核心网转发 ACK给 PoC Server„
步骤 S216 PoC Server通过核心网向用户 C发送 ACK确认响 步骤 S217 , 核心网将 ACK确认响应发送给用户 C。
步骤 S218 , 用户 B通过各种方式 （可以在注册上线后获取， 且本发明实施例实现在用户注册上线前， 即离线状态下获取）， 通 过发送请求, ^口 XCAP ( Extensible Markup Language Configuration Access Protocol , 可扩展标记语言配置接入协议） 请求或 SIP ( Session Initial Protocol,会话初始化协议 )请求,向 InviteLogBox 获取自己的呼叫记录信息， 或者 InviteLogBox根据离线呼叫信息 通过各种方式即时或定期提供给离线的被叫用户 B。
步骤 S219 , InviteLogBox返回 OK, 并将用户 B的被呼叫记 录发送给用户 B。
步骤 S220, 用户 B设置自己的呼叫信息记录方式， 和被叫策 略。
在该步骤中， 用户的可设置项包括但不限于：
1 )保存某个、 某些或所有用户对自己的 1-1、 ad _ hoc会话邀 请记录；
2 )保存某个、 某些或所有群组的会话邀请记录。
3 )设置呼叫日志记录保存时间长度（即： 保存时长）。
4 )设置主叫用户优先级别， 即对主叫用户设定级别， 当用户 上线后， 服务器优先主动为级别高的主叫用户进行呼叫， 邀请用 户加入现存的会话中。
5 )设置群组的优先级别， 即对群组设定级别， 当用户上线后， 服务器优先主动为级别高的群组进行呼叫， 邀请用户加入现存的 会话中。 6 )设置按时间优先呼叫， 即设置按某个时间段或最近时间发 生的呼叫， 进行邀请。
7 )设置并发邀请个数， 即用户上线后， 如果当前还存在多个 会话， 服务器按照用户设置的并发邀请个数 N, 选择 N个会话发 起会话邀请。
8 )针对个人或群组设置不邀请列表， 即用户上线后， 即使当 前这些个人或群组的会话还存在， 服务器也不能发起邀请。
步骤 S221 , InviteLogBox接受用户 B的设置， 返回 OK信息， 发送呼叫记录。
在上述步骤 S218~S221 中， 用户 B获取被叫记录和设置呼叫 策略和用户注册上线不存在必然的时间的先后关系， 可以灵活设 置， 实现用户与 InviteLogBox的信息交互即可。
步骤 S222, 用户 B向核心网发送 SIP Register请求， 注册上 线。
步骤 S223 , 核心网返回 200 OK。
步骤 S224, 核心网向 PoC Server发送 Register, 通知用户 B 上线。
步骤 S225 , PoC Server返回 200 OK。
步骤 S226, PoC Server向 InviteLogBox发送呼叫策略查询请 求， 获取用户 B的上线呼叫策略。
步骤 S227 , InviteLogBox返回 OK, 并返回用户 B的被叫策 略。
步骤 S228, PoC Server检查到用户 A建立的会话依然存在， 并根据用户 B的被叫策略， 向用户 B发送 SIP Invite请求， 主动邀 请用户 B加入用户 A建立的会话中。
步骤 S229, 核心网将 Invite请求发送给用户 B。
步骤 S230, 用户 B返回 200 OK, 同意加入会话。
步骤 S231 , 核心网将 200 OK响应转发给 PoC Server。
步骤 S232, PoC Server发送 ACK确认响应。 步骤 S233 , 核心网将 ACK转发给用户 B。
本实施例中的 PoC 会话服务器在被叫用户离线时， 通知 InviteLogBox保存该用户的离线呼叫信息，当用户上线并设置有呼 叫策略时， 根据呼叫策略按该用户的意愿将该用户加入未终止的 会话中， 减少了用户遗失重要会话信息的几率。
本发明实施例三提供一种会话系统， 如图 3所示， 包括： 主叫用 户 1、 会话服务器 3、 记录网元 5以及被叫用户 7。
其中，会话服务器 3用于接收处于会话中的主叫用户 1邀请被叫 用户 7加入所述会话的呼叫请求， 根据所述呼叫请求检测被叫用户 7 是否在线， 当被叫用户 7上线时， 进一步检测记录网元 5记录的离线 呼叫信息中的所述会话是否终止， 如果未终止， 则将被叫用户 7加入 所述会话中；
记录网元 5用于记录所述邀请被叫用户 7加入所述会话的离线呼 叫信息。
其中， 会话服务器 3包括：
接收模块 31 ,用于接收处于会话中的主叫用户 1邀请被叫用户 7 加入所述会话的呼叫请求；
第一检测模块 33, 用于检测被叫用户 7是否上线；
记录触发模块 35, 用于在第一检测模块 33检测到被叫用户 7离 线时触发记录网元 5记录所述邀请被叫用户 7加入所述会话的离线呼 叫信息；
第二检测模块 37, 用于在第一检测模块 33检测到被叫用户 7上 线时进一步检测被叫用户 7的离线呼叫信息中的会话是否终止；
会话邀请模块 39, 用于将第一检测模块 33检测到上线的被叫用 户 7加入到所述离线呼叫信息中第二检测模块 37检测到的未终止的 会话中。
其中， 会话服务器 3还可以进一步包括： 呼叫策略查找模块 38, 用于查找被叫用户 7的呼叫策略， 供会话邀请模块 39根据所述呼叫 策略将被叫用户 7加入与所述呼叫策略对应的会话中。 其中， 记录网元 5 包括： 离线呼叫信息记录模块 51 , 用于记录 被叫用户 7离线时主叫用户 1邀请被叫用户 7加入会话的离线呼叫信 息， 将所述离线呼叫信息发送给离线的被叫用户 7。
该记录网元 5进一步包括：
第一时长设置模块 53 , 用于设置离线呼叫信息记录模块 51记录 的离线呼叫信, 的保存时长。
呼叫策略记录模块 55 , 用于记录被叫用户 7根据离线呼叫信息 记录模块 51的离线呼叫信息设置的呼叫策略。
第二时长设置模块 57, 用于设置述呼叫策略记录模块 55记录的 呼叫策略的保存时长。
在记录网元 5中， 当离线呼叫信息的保存时长超过第一时长设置 模块 53设置的保存时长后， 或呼叫策略的保存时长超过第二时长设 置模块 57设置的保存时长后，删除对应的离线呼叫信息和呼叫策略， 或者将对应的离线呼叫信息和呼叫策略设置为无效状态并保存曰志 数据以释放存储空间，并对记录的离线呼叫信息和呼叫策略进行有序 管理。
在该装置中， 记录网元 5可以集成在会话服务器 3上， 也可以独 立存放。 记录网元 5与会话服务器 3和被叫用户 7进行交互， 保存被 叫用户 7的离线呼叫信息， 减少了遗失重要会话信息的几率； 并通 过呼叫策略的设置和调用， 增强了用户体验。
本发明实施例的技术方案具有以下优点：
