The second update 81 establishes the upper second communication and the upper communication respectively established by 62 The signaling interaction of the MS SGSN line routing update, the second block 82 is completed by the update, and the message is switched to the SRNS through the interface.
本 , 第二更新 MS SGSN 交互, 通 建立 所 建立的第二通信 和 BSS建立的 BSS SGSN 同的第 通 The second update MS SGSN interacts with the establishment of the established second communication and the BSS SGSN established by the BSS.
( U-PS接口連接) 中特MS SGSN在 由 更新流程中的相 消息, 以完成 由 更新。 均上 本 相比, 本 中 的第二更新 是通 MS SGSN交互未完成的路由 更新流程, 而 SRNS上 的下行分組數 仍然是通 第 通信 和第二通信 的, 而 了 S 的承載和控制 的特性,支持控制 和用戶 的分別 , 增 了 的 活性。  (U-PS interface connection) The special MS SGSN is in the update process by the phase message to complete the update. Compared with the above average, the second update in the present is the routing update process that is not completed by the MS SGSN interaction, and the number of downlink packets on the SRNS is still the communication and the second communication, and the bearer and control of the S are Features, support for control and user differentiation, increased activity.
步 , 接收 61 接收到的上 切換 消息中 帶有 SRNS的上下文,本 的 BSS 可以 步包括第 83, 于根 上 SRNS的上下文, 接收SRNS 建立 62所建立的上 第 通信 的 的下行分組數 建立 62所建立 的上 第二通信 向上 MS 送上 下行分組數 &。  Steps: Receiving 61 the context of the SRNS received in the received handover message, the BSS of the present step may include the 83th, in the context of the SRNS on the root, and receive the number of downlink packets established by the SRNS establishment 62 to establish 62 The established second communication sends the number of uplink and downlink packets to the MS.
本 ,通 建立 所建立的 BSS SRNS 同的第 通信 , SRNS可以直接 BSS 令交互, 而  Ben, the establishment of the established BSS SRNS with the same communication, SRNS can directly BSS to make the interaction, and
的 SGSN, 減少了 S 統同切換 中 岡 同的交互, 而可 以減少 的信令 荷和切換的 建立 所建立的 BSS SRNS 同的第 通信 , SRNS上的下行分組數 可以直接 通 第 通信 至 BSS, 前特到 的 SGSN, 減少了 切換的 。 The SGSN reduces the interaction between S and the switch, and can reduce the signaling load and the establishment of the BSS SRNS established by the handover. The number of downlink packets on the SRNS can be directly communicated to the BSS. The special SGSN reduces the switching.
本 可以提供 S 統同的切換 統,包含上 本 、 本 和本 提供的 BSS, 以及均上BSS通信的 SRNS。 其 , SRNS可以包括 , 于 BSS 同的第 接口向 BSS 送上 切換 消息。 上 切換 消息中 可以 步 帶有 SRNS的上下文, 相 , SRNS 可以 步包括第二 , 于 BSS的建立 所建立的上 第 通信 向 BSS 的下行分組數 。 This can provide the same switching system of S, including the BSS provided in the current, the present and the present, and the SRNS in the BSS communication. The SRNS may include sending a handover message to the BSS on the same interface as the BSS. On the switch message can The step with the SRNS context, phase, SRNS may include the second, the number of downlink packets of the upper communication to the BSS established by the establishment of the BSS.
本 , 通 BSS所建立的 BSS SRNS 同的 5 通信 , SRNS可以直接 BSS 令交互, 而  Ben, through the BSS SRNS established by BSS, the same 5 communication, SRNS can directly BSS to make interaction, and
的 SGSN, 減少了 S 統同切換 中 岡 同的交互, 而 可以減少 的信令 荷和切換的 BSS 所建立的 BSS SRNS 同的第 通信 , SRNS上的下行分組數 可以 直接通 第 通信 至 BSS, 前特到 的 SGSN,0 少了切換的 。  The SGSN reduces the interaction between S and the switch, and can reduce the signaling load and the BSS SRNS established by the switched BSS. The number of downlink packets on the SRNS can be directly communicated to the BSS. The special SGSN, 0 has less switching.
