Description

一种减少延时的方法及 RNC 技术领域
本发明涉及通信领域, 尤其涉及一种减少延时的方法及 RNC。 背景技术
在 UMTS ( Universal Mobile Telecommunications System, 通 用移动通信系统) 中, 若主叫用户要对被叫用户进行语音通信, 首 先主叫 UE ( User Equipment , 用户设备) 和被叫 UE 需要分另1 J和网 络连接, 随后主叫 UE和被叫 UE通过网络进行语音通信。 其中, 一 个 UMTS 系统至少包括: MSC ( Mobi le-services Swi tching Centre, 移动业务交换中心) , 至少一个 RNC ( Radio Network Control ler , 无线网络控制器) , 一个基站 nodeB, 以及至少一个主叫 UE和被叫 UE。
通常, 主叫 UE呼叫被叫 UE 的流程如图 1 所示: ( 1 ) 主叫 UE 和 RNC 建立 RRC ( Radio Resource Control , 无线资源控制协议) 连接过程; ( 2 ) 主叫 UE 发送第一 CM Service Reques t ( Connect Management Service Request, 连接管理月良务请求) 至 MSC, 请求 服务; ( 3 ) MSC 和 RNC 进行安全认证过程, 验证主叫 UE 是否为合 法用户, 以及 MSC和 RNC对主叫 UE进行加密的过程, 若主叫 UE不 是合法用户, 则中断呼叫流程; ( 4 )若主叫 UE是合法用户, 则 MSC 接收主叫 UE 的呼叫请求, 并发送 CM Service Accept ( Connect Management Service Accept , 连接管理月良务接^:反馈) 至主叫 UE;
( 5 ) 主叫 UE发送 Call Setup 消息 ( 包含被叫 UE 的信息, 如电话 号码)至 MSC; ( 6 ) MSC发送 Call Proceeding反馈消息至主叫 UE;
( 7 ) MSC发送第一 RAB assignment reques t ( Radio Access Bearer assignment request, 无线接人 ^载分西己请求) 至 RNC , 以使得 RNC 进行 RAB指派; ( 8 ) 主叫 UE和 RNC进行建立 RB ( Radio Bearer, 无线承载 ) 过程; ( 9 ) 在建立 RB 完成后, RNC 发送第一 RAB assignment r epons e ( Radio Access Bearer assignment r epons e , 无线接入承载分配响应 ) 至 MSC; ( 10 ) MSC发送 Paging寻呼消息 至被叫 UE; ( 11 ) 被叫 UE 和 RNC建立 RRC连接过程; ( 12 ) 被叫 UE发送 Paging Re s pons e寻呼响应消息至 MSC , 请求服务; ( 13 ) MSC和 RNC进行安全认证过程, 验证被叫 UE是否为合法用户, 以及 MSC和 RNC对被叫 UE进行加密的过程, 若被叫 UE 不是合法用户, 则中断呼叫流程; ( 14 ) 若被叫 UE 是合法用户, 则 MSC发送 Call Setup 消息至被叫 UE; ( 15 ) 被叫 UE发送 Call Confirm反馈消息 至 MSC; ( 16 ) MSC发送第二 RAB assignment request 至 RNC, 以 使得 RNC进行 RAB指派; ( 17 ) 被叫 UE和 RNC进行建立 RB过程; ( 18 ) 在建立 RB 完成后, RNC 发送第二 RAB assignment reponse 至 MSC; ( 19 ) 被叫 UE发送 Alerting振铃消息至 MSC; ( 20 ) MSC 发送 Alerting 振铃消息至主叫 UE; ( 21 ) 被叫 UE 摘机, 并发送 Connect连接消息至 MSC; ( 22 ) MSC发送 Connect连接消息至主叫 UE。 这时主叫 UE和被叫 UE可以开始通话。 其中, 这里提到的连接 主叫 UE和被叫 UE的可以是相同的 MSC, 也可以是不同的 MSC; 如果 连接主叫 UE和被叫 UE的是不同的 MSC, 那么连接主叫 UE的 MSC和 连接被叫 UE的 MSC之间会进行相应的通讯。
从现有的主叫 UE呼叫被叫 UE的流程可以看出, 主叫 UE建立连 接的过程和被叫 UE 建立连接的过程是两个独立的串行过程。 因 此, 主叫 UE 呼叫被叫 UE 的时间是主叫 UE 建立连接的时间与被叫 UE建立连接的时间的总和, 进而产生了较长的呼叫延时 (通常情况 下为 5 秒左右) , 在网络拥塞的情况下, 甚至会花费更长的时间。 为了减少呼叫延时, 现有方法 1 的流程如图 2 所示: MSC 通常在获 得主叫 UE发送的 Call Setup消息之后就发送寻呼消息至被叫 UE, 以使得被叫 UE开始建立连接。 即流程图 1 中, 在步骤 ( 5 ) 主叫 UE 发送 Call Setu 消息至 MSC之后, MSC就可以给被叫 UE发送 Paging 寻呼消息, 即完成步骤 ( 10 ) 以及后续的被叫过程, 而无需等待步 骤 ( 9 ) 主叫 UE 建立好 RB之后再开始步骤 ( 10 ) 寻呼被叫 UE, 这 样主叫 UE和被叫 UE 的流程很大部分能够并行完成, 因此能减小寻 呼过程中产生的呼叫延时。 然而这种方法需要对 MSC 进行改进, 即 MSC需要在步骤( 5 )后, 而不是步骤( 9 )后进行对被叫 UE的寻呼。 对于该方法, 如果 MSC 不进行改进, 整个呼叫流程就没有改变。 RNC没有任何作为, 完全依赖于 MSC的改进。
现有技术中还提供了一种方法 2, 在上述现有方法 1 的基础上 进行再次改进: 步骤 ( 19 ) 被叫 UE发送 Alerting 振铃消息至 MSC 在步骤 ( 15 ) 后就执行, 即在步骤 ( 16 ) 、 ( 17 ) 以及 ( 18 ) 前 ( RB 建立过程完成之前) 发送, 主叫步骤 ( 7 ) 、 ( 8 ) 以及 ( 9 ) 改在步 骤 ( 19 ) 之后进行。 但是对于方法 2, 虽然发送 Alerting振铃消息 的时间提前了, 但是要真正使主叫 UE和被叫 UE 能通话, 还是必须 等到 RB建立完成后, 所以呼叫建立所需的整个时间并没有减少。 发明内容
