Abstract: Described are call handling methods performed by a carrier network or client stations. A method performed by a carrier network includes designating rules for call handling for an account, receiving first and second voice calls for the account, wherein the voice calls may be either an incoming calls or originated calls and handling the first and second voice calls for the account based on the rules. A method performed by a client station includes receiving a first invitation to a first call, responding to the first invitation causing the first call to be active, receiving a second invitation to a second call while the first call remains active and responding to the second invitation causing the second call to be active and the first call to be on hold, the client station is prevented from originating a call when one call is active and one call is on hold.

Abstract: Determining whether to operate in a single radio access technology (RAT) mode or a dual RAT mode for a user equipment (UE) having a radio capable of communicating using at least a first RAT and a second RAT. The UE may determine whether current path loss for the first RAT exceeds a maximum path loss. Based on the results of determining whether the current path loss for the first RAT exceeds the maximum path loss, the UE may determine whether to operate in the single RAT mode or the dual RAT mode. Accordingly, based on this determination, the UE may operate in the single RAT mode or the dual RAT mode based on the determination.

Abstract: A station that performs methods related to emergency calls. In one example, the station determines that a first connection to a cellular network is unavailable, the client station being associated with a home network having a home Public-Safety Answering Point (PSAP), the station disposed at a location outside the home network, the location having a remote PSAP. The station determines a second connection to a WiFi network is available, establishes the second connection to the WiFi network and performs an emergency call over the WiFi network. The emergency call being routed to the remote PSAP associated with the location. In another example, the station determines it is capable of performing an emergency call over a cellular network, receives a request to perform an emergency call, determines whether a circuit switched radio access technology (CS-RAT) is available and performs the emergency call over a WiFi network when the CS-RAT is unavailable.

Abstract translation: 执行与紧急呼叫有关的方法的电台。 在一个示例中，站确定到蜂窝网络的第一连接不可用，该客户站与具有归属公共安全应答点（PSAP）的家庭网络相关联，该站位于归属网络外部的位置， 该位置具有远程PSAP。 站确定到WiFi网络的第二连接可用，建立到WiFi网络的第二连接并且通过WiFi网络执行紧急呼叫。 紧急呼叫被路由到与该位置相关联的远程PSAP。 在另一个示例中，站确定它能够通过蜂窝网络执行紧急呼叫，接收执行紧急呼叫的请求，确定电路交换无线电接入技术（CS-RAT）是否可用并且执行紧急呼叫 当CS-RAT不可用时的WiFi网络。
