       在通信系統(tǒng)中參與的終端（UA）之間信息的交互全部基于自身能力（Capability Information）；通常他們交換自身能力是初始通信設(shè)置中的一個強制內(nèi)容，有時終端提供這些信息則是為了回應對方的特殊要求。在WCDMA或LTE網(wǎng)絡(luò)中，終端是在RRC連接配置完成消息中攜帶這些表明其性能的特殊消息。

      這些有關(guān)自身能力（Capability Information）的信息對于溝通中的雙方來說都非常重要；這些信息可以自行配置后才可以與另一方進行溝通。此外在進行即時消息交流時這些信息也非常重要，因為在許多情況下信息交流失敗僅僅是因為終端不支持特定功能或特性。

      在IMS系統(tǒng)和基于IMS系統(tǒng)的應用程序中也使用類似的機制。對于IMS應用程序有幾種不同的機制消息，它們都攜帶了UE能力相關(guān)信息。對于IMS系統(tǒng)的故障排除，在開始進行故障排除之前，最好檢查一下UE功能的相關(guān)信息。


1.IMS系統(tǒng)中攜帶UE能力的SIP消息

        在IMS系統(tǒng)以下七種消息中攜帶了含有UE能力的消息，這些消息分別表明了其支持的功能或性能；


  •     注冊（REGISTER）中攜帶的UE能力消息

  •     發(fā)布（PUBLISH）中攜帶的UE能力消息

  •     選項（OPTION）中攜帶的UE能力消息

  •     通知（NOTIFY）中攜帶的UE能力消息

  •     邀請（INVITE）中攜帶的UE能力消息

  •    180振鈴中（Ringing）中攜帶的UE能力消息

  •    200（OK）應答中攜帶的UE能力消息


2.攜帶UE能力的消息內(nèi)容（下文中紅色字體部分）
