摘要： A system and method for identifying the accessibility of a base station in a communication system. The system includes at least one Closed Subscriber Group (CSG)-Open (hybrid) base station. The base station can apply a base station identifier, such as a CSG identifier, as a cyclic redundancy check (CRC) mask to a first broadcast channel communication and can include the base station identifier in the payload of, or as a CRC mask applied to, a second broadcast channel communication. A mobile station can determine from the base station identifier in the first broadcast communication if the mobile station is a member authorized closed access to the base station. The mobile station can determine from the base station identifier in second first broadcast communication if the mobile station is a non-member authorized open access to the base station.

摘要： A subscriber station can efficiently determine an accessible base station by scanning a subset of base stations based on an optimized list received from a serving base station. The subscriber station includes a white list that contains information regarding a number of closed subscriber group (CSG) base stations to which the subscriber station is subscribed. The subscriber station can transmit a request message that includes one or more of: indication of whether the detected identifier of the femto base station is in the whitelist or not; and its location information. In response, the base station can send a message that includes the nearby femtocells and whether the femtocell is accessible or inaccessible to the subscriber station. The femto base station can be designed to be in transmission off mode when none of its subscribers is in its coverage. The serving base station can select a set of the accessible femtocells to the subscriber station, and request the selected femtocells to monitor an uplink signaling of the subscriber station so that the femtocell can be awaken when the femtocell is in transmission off mode or be aware that the subscriber station is in proximity, if the uplink signaling is detected.

摘要： Prior to a change in a configuration, such as a change to the carrier frequency, bandwidth, base station type, and so forth of the base station, the base station can inform a subscriber station to prepare for the reconfiguration by sending a message to the subscriber station. The message informs the subscriber station regarding the change in configuration and a timing regarding the change. The base station can command the subscriber station to handover to the serving base station with the new configuration or the subscriber station can choose to handover to the serving base station with the new configuration. The subscriber station can perform network reentry to the serving base station with the new configuration at the time of or after the new configuration is effective. A communication context between the stations can be maintained and the network reentry can be optimized by omitting one or more operation procedures.
摘要翻译：在更改配置之前，例如对基站的载波频率，带宽，基站类型等的改变，基站可以通知向用户站准备重新配置，通过向用户站。该消息通知用户站关于配置的变化和关于改变的定时。基站可以命令用户站用新配置切换到服务基站，或者用户台可以选择用新配置切换到服务基站。用户站可以在新配置有效时或之后使用新配置来对服务基站执行网络重入。可以维护站之间的通信环境，并且可以通过省略一个或多个操作过程来优化网络重入。

摘要： A first base station and mobile station are capable of mitigating interference resulting from communications from a second base station. The base station can determine if at least a portion of a paging slot overlaps with an available interval (AI) of the second base station in which the second base station transmits. The first base station adjusts an occurrence of the paging slot such that the paging slot overlaps and/or occurs within an unavailable interval (UAI) of the second base station wherein the base station does not transmit or transmits with limited resources.The mobile station also can determine if at least a portion of a listening slot overlaps with the AI and, using the same procedure that the first base station uses to recalculate the paging slot, recalculates the listening slot such that the listening slot overlaps and/or occurs within the UAI of the LDC mode.
