    • Femto cells that extend mobile network coverage into customer premises operate in a frequency band typically assigned to a macro network. As disclosed, to facilitate system discovery and registrations of mobile stations with femto cells, a carrier designates one the channels within the band as a primary channel for its femto cells. For example, neighbor list messages transmitted by macro network base stations can provide frequency and PN code information directing mobile stations to search the primary channel for a PN code of the femto cells. Also, a mobile station PRL may identify femto cells by SID/NID. The SID is that of the carrier's macro network, whereas the NID may be a NID of the macro network or one specifically assigned to femto cell operations. The PRL uses frequency acquisition information for the femto cells that is the same as or similar to that for one of the macro networks.
    • 将移动网络覆盖扩展到客户驻地的毫微微小区在通常分配给宏网络的频带中操作。 如所公开的,为了促进具有毫微微小区的移动站的系统发现和注册,载波将频带内的信道指定为其毫微微小区的主要信道。 例如,由宏网络基站发送的邻居列表消息可以提供频率和PN码信息,其指示移动台在主信道上搜索毫微微小区的PN码。 此外,移动站PRL可以通过SID / NID来识别毫微微小区。 SID是运营商的宏网络的SID,而NID可以是宏网络的NID或专门分配给毫微微小区操作的NID。 PRL使用与一个宏网络相同或类似的毫微微小区的频率获取信息。

    • A femto cell at a customer premises, such as an IP-based femto Base Transceiver System (IP-BTS), can be configured as a "private access" node intended to service a limited set of mobile stations. However, mobile stations not associated with the private femto cell may acquire and lock onto the femto BTS. To avoid service blockages in such cases, the private femto BTS will allow call access attempts by, and call deliveries to, a non-associated mobile station, despite the "private access" configuration. However, upon completion of call set-up, the non-associated mobile station is directed to initiate handoff, from the private femto cell coverage provided by the femto BTS into a cell coverage of a base station of the macro network, to conserve femto cell resources for use in servicing calls of the associated mobile station(s).
    • 诸如基于IP的毫微微基站收发器系统(IP-BTS)之类的客户驻地的毫微微小区可被配置为旨在服务有限的一组移动站的“专用接入”节点。 然而,与私有毫微微小区无关的移动站可以获取并锁定到毫微微BTS。 为了避免在这种情况下的服务阻塞,私人毫微微BTS将允许呼叫接入尝试,并且呼叫非接入移动台的传送,尽管有“私有接入”配置。 然而,在完成呼叫建立之后,非关联移动台被指示从毫微微BTS提供的私人毫微微小区覆盖范围开始到宏网络的基站的小区覆盖范围内的切换,以节省毫微微小区 用于维护相关移动台的呼叫的资源。
