    • A system and method for handoff in an integrated cell. A user equipment selects an integrated cell as a target cell supporting a target network based on a white list and physical cell identities. A cell-to-cell handoff is performed to the target cell. After the cell-to-cell handoff, a base station of the target cell establishes a communication session directly to a service. Then, the user equipment determines whether or not a physical cell identity of a base station of the target cell is an integrated physical cell identity. The user equipment turns on a module for the target network when the physical cell identity of the base station is determined to be the integrated physical cell identity. A heterogeneous-network handoff is then performed, and the base station communicates directly with a service server using a mapping table in order to seamlessly provide the service to the user equipment.
    • 用于集成单元中切换的系统和方法。 用户设备基于白名单和物理小区标识,选择集成小区作为支持目标网络的目标小区。 对目标小区执行小区切换。 在小区到小区切换之后,目标小区的基站直接建立到服务的通信会话。 然后,用户设备确定目标小区的基站的物理小区身份是否是综合的物理小区身份。 当基站的物理小区标识被确定为集成的物理小区标识时,用户设备打开用于目标网络的模块。 然后执行异构网络切换,并且基站使用映射表直接与服务服务器通信,以便无缝地向用户设备提供服务。

    • Described embodiments provide a method of a circuit switched (CS) fallback procedure at a first network providing only a packet switched (PS) service. A CS fallback procedure may be initiated upon a receipt of a call associated with a CS service. One of carriers assigned to a second network that provides a circuit switched (CS) service may be selected. Then, a second network cell mapped to a serving cell of the first network and using the selected carrier may be selected as a target cell. The user equipment may be handed over o to the selected second network cell in order to provide a requested CS service.
    • 所描述的实施例提供了仅提供分组交换(PS)服务的第一网络处的电路交换(CS)回退过程的方法。 可以在接收到与CS服务相关联的呼叫时发起CS回退过程。 可以选择分配给提供电路交换(CS)服务的第二网络的运营商之一。 然后,可以选择映射到第一网络的服务小区并使用所选择的载波的第二网络小区作为目标小区。 可以将用户设备交给所选择的第二网络小区,以便提供所请求的CS服务。

    • The disclosure is related to measuring macrocell quality of a macrocell using femtocells. A method may be provided for measuring macrocell quality of at least one macrocell using a femtocell base station. The method may include measuring, by the femtocell base station, macrocell quality of at least one macrocell based on event information, generating macrocell quality report information based on a result of the measuring, and transmitting the generated macrocell quality report information to a server through a femtocell gateway. The measuring macrocell quality may include determining whether a macrocell identifier is present in the event information, measuring the macrocell quality of a target macrocell corresponding to the mermen identifier of the event when the macrocell identifier is present in the event information, and measuring the macrocell quality of substantially all neighbor macrocells when the macrocell identifier is absent from the event information.
    • 本公开涉及使用毫微微小区测量宏小区的宏小区质量。 可以提供一种用于使用毫微微小区基站测量至少一个宏小区的宏小区质量的方法。 该方法可以包括:基于事件信息,由毫微微小区基站测量至少一个宏小区的宏小区质量,基于测量结果生成宏小区质量报告信息,并通过以下步骤将所生成的宏小区质量报告信息发送到服务器 毫微微蜂窝网关。 所述测量宏小区质量可以包括确定所述事件信息中是否存在宏小区标识符,当所述宏小区标识符存在于所述事件信息中时,测量与所述事件的美人标识对应的目标宏小区的宏小区质量,以及测量所述宏小区质量 当从事件信息中不存在宏小区标识符时,基本上所有的邻居宏小区。
