Abstract: Technologies directed to network address translation based on logical channels in a shared private network with a single ingress to an ISP and multiple customer devices are described. One method receives a first public IP address assigned to an endpoint device by an ISP. The method creates a sub-interface on a WAN interface and adds a first rule that translates the first public IP address to a first private IP address assigned to the customer STA and a second rule that translates the first private IP address to the second public IP address. The first customer STA creates a second sub-interface between the customer STA and the endpoint device, adds a third rule that translates the first private IP address to a second private IP address assigned to the first endpoint device, and adds a fourth rule that translates the second private IP address to the first private IP address.

Abstract: Sending short message service (SMS) messages and receiving a response report based at least in part on the sent SMS message, even if a communicative connection with the mobile communications network had been severed, so that duplication of the SMS message is avoided is disclosed. In this case, a communicative connection may be re-established and used to receive an acknowledgment from the mobile communications network and subsequently send another acknowledgement to the mobile communications network. The UE may also be configured to send an information element to the one or more elements of the mobile communications network to indicate that a communicative connection with the network is to remain established so that acknowledgements may be reconciled between the UE and the network. Additionally, the mobile communications network may be configured to transmit the SMS message only after receiving the acknowledgement from the UE, to avoid sending duplicate SMS messages.

Abstract translation: 发送短消息服务（SMS）消息并且至少部分地基于所发送的SMS消息来接收响应报告，即使与移动通信网络的通信连接已被切断，从而公开了避免SMS消息的复制。 在这种情况下，可以重新建立通信连接并用于从移动通信网络接收确认，并且随后向移动通信网络发送另一个确认。 UE还可以被配置为向移动通信网络的一个或多个元件发送信息元素，以指示与网络的通信连接将保持建立，使得可以在UE和网络之间协调确认。 此外，移动通信网络可以被配置为仅在从UE接收到确认之后才发送SMS消息，以避免发送重复的SMS消息。

Abstract: Receiving short message service (SMS) messages and providing a response report based at least in part on the received SMS message is disclosed. A user equipment (UE) may receive an SMS message via a communications link between the UE and a mobile communications network. The UE may be configured to determine if the SMS message was received with or without error. Based at least in part on this determination, the UE may generate the response report to provide to the mobile communications network. The UE may further identify that the communications link between itself and the mobile communications network may be severed. As a result, the UE may reestablish the communications link with the mobile communications network and then transmit the response report.

Abstract: Receiving short message service (SMS) messages and providing a response report based at least in part on the received SMS message is disclosed. A user equipment (UE) may receive an SMS message via a communications link between the UE and mobile a mobile communications network. The UE may be configured to determine if the SMS message was received with or without error. Based at least in part on this determination, the UE may generate the response report to provide to the mobile communications network.

Abstract: Systems and methods for routing pages to cellular phones (UE) not connected to a cellular network, but connected to a wireless local area network (I-WLAN), are disclosed. The system can route cellular pages to disconnected cellular devices using 3GPP AAA components, such as a Third Generation Partnership Project authentication, authorization, and accounting (3GPP AAA) server. The system can route pages via a home location register (HLR) connected to the I-WLAN or a mobile switching center (MSC) connected to the I-WLAN. The system can determine an appropriate MSC based on proximity of the MSC to the last known location of the UE, for example, or based on the MSC with the lowest utilization rates. The system can send a page to the UE via the I-WLAN instructing the UE to reconnect to the cellular network. The system can then send cellular data to the UE using the cellular network.

Abstract: Technologies directed to performing switchover across Internet service providers in a last-mile network are described. One method includes receiving, by a first wireless device, a destination address, a first network address of a first network addressing scheme, and a first message. The method further includes determining a first status of at least one of a first NSP or a second NSP. The first NSP uses a second network addressing scheme and the second NSP uses a third network addressing scheme. The method further includes determining a second network address of the third network addressing scheme. The method further includes sending, using the second NSP the second network address and the first message. The method further includes determining a third network address of a fourth network addressing scheme and sending to a fourth wireless device corresponding to the destination address the third network address and the first message.

Abstract: A secure communication channel is established between network devices separated by an unsecured physical space by dynamically performing server/client resolution based on comparison of unique identifiers of the devices. After a link between a first network device and a second network device is established, the devices exchange start frames in accordance with a network security protocol such as the Media Access Control Security (MACsec) protocol. Comparison logic at the first network device compares a value of a unique identifier of the first network device to a value of a unique identifier of the second network device obtained from the start frame transmitted by the second network device, and vice versa. Based on the comparison, one of the devices assumes a server/authenticator role, and the other device assumes a client/supplicant role. The devices operate in their determined roles to perform an authentication process and thereby establish a secure communication channel.

Abstract: Technology is described for using a first key to secure communications over a network link between a server and a client. A second key may be identified. A first message may indicate the server may receive data from the client using the second key but not to transmit data to the client using the second key, and that the first key is valid for sending and receiving data between the server and the client. A second message may indicate that the client may send and receive data with the server using the second key, and that the client may receive data from the server using the first key but not transmit data to the server using the first key. A third message may indicate that the server may send and receive data with the client using the second key, and that the first key is invalid for sending and receiving data between the server and the client.
