技術領域

本發明涉及處于增強前向接入信道(FACH，Forward Access Channel)態下的終端對系統信息及測量控制消息的處理技術，尤其涉及一種增強前向接入信道態下小區信息處理方法及裝置。

背景技術

在時分雙工同步碼分多址(TDD-SCDMA，Time Division Duplexing-Synchronous Code Division Multiple Access)系統中，在沒有引入增強前向接入信道(E-FACH，Ehance Forward Access Channel)的情況下，終端在FACH態只能工作在主載頻，對于同頻異頻只能進行小區重選相關評估，而不會進行測量準則相關的評估，終端在FACH態會不斷監控鄰近小區，并根據服務小區信號情況進行鄰區測量的評估，以便在有好的鄰區出現或服務小區信號變差時選到一個合適的鄰區。引入增強FACH后，終端在增強FACH態可以工作在主載頻，也可以工作在輔載頻，在增強FACH態下不僅要進行小區重選相關的評估，還可以接收測量控制進行測量準則評估及上報。

對于增強FACH，在第三代合作伙伴計劃(3GPP，3rd Generation Partnership Project)25.331a10協議8.4.1.6.1及8.4.1.6.2中，描述了終端從專用信道(DCH，Dedicated Channel)態轉入增強FACH態后對同頻異頻測量的處理。以同頻為例，原文描述如下：

8.4.1.6.1Intra-frequency measurement

Upon transition from CELL_DCH to CELL_FACH/CELL_PCH/URA_PCH state,the UE shall:

1>stop intra-frequency type measurement reporting；

1>if the transition is due to a reconfiguration message which included the IE"Primary CPICH info"(for FDD)or"Primary CCPCH info"(for TDD),and the UE selects a cell other than that indicated by this IE on the current frequency(in case the IE"Frequency info"is not received)or other than that indicated by this IE on the frequency indicated by the IE"Frequency info"(when the IE"Frequency info"is included)；or

1>if the transition is due to a reconfiguration message which does not include the IE"Primary CPICH info"(for FDD)or"Primary CCPCH info"(for TDD)；or

1>if the transition is not due to a reconfiguration message:

2>delete the measurements of type intra-frequency associated with the variable MEASUREMENT_IDENTITY.

1>begin monitoring cells listed in the IE"intra-frequency cell info list"received in System Information Block type 12(or System Information Block type 11,according to subclause 8.1.1.6.11).

1>for 1.28Mcps TDD,if after state transition the UE enters CELL_FACH state and is working on the secondary frequency:
