A related method is provided for exchanging secure communications between senders and recipients, where the communication device(s) or point(s)-of-presence associated with the recipients can vary over time.

A method for operating a first distributed unit (DU) includes participating in a link layer context transfer with a second DU, establishing a user data path for a mobile device, the user data path connecting the mobile device with a centralized unit (CU) including a radio control protocol entity communicating with the mobile device, and storing first user data for the mobile device received from the CU and second user data for the mobile device received from the second DU. The method includes establishing a connection with the mobile device, sending the first user data and the second user data to the mobile device, and adapting the link layer context to operate in the first DU for exchanging data between the CU and the mobile device, wherein adapting the link layer context includes associating an uppermost protocol layer of the first DU with a lowest protocol layer of the CU.

A communication device (UE) conducting wired and/or wireless communications may issue service requests using zero-round-trip-time (zero-RTT) connectivity. The UE may obtain, prior to initiating an application, an address corresponding to a service and a security credential for use in accessing the service. The UE may receive, after initiating the application, an instruction to issue a service request, and generate the service request that may include a service identifier corresponding to the service, the address corresponding to the service, and the security credential for use in accessing the service. The UE may then transmit the service request to an edge server associated with the service. The edge server may route the service according to the service identifier. Multiple data centers/servers may advertise their services to the edge server associated with the service, facilitating fast routing of the service request by the edge server associated with the service.

A method includes sending identification information for a mobile hotspot device from that device to a cloud-based computer processing system, sending identification information for a security monitoring device from that device to an app on a user's mobile device, prompting the user, via the app, to provide the identification information for the mobile hotspot device to the user's mobile device, and sending a pairing request from the app to the cloud-based computer processing system. The pairing request includes the identification information for the mobile hotspot device that was provided by the user and the identification information for the security monitoring device. The method further includes sending a response to the pairing request from the cloud-based computer processing system to the app, and using information in the response to establish a wireless connection between the mobile hotspot device and the security monitoring device.

Techniques for location source control for paired devices are described. Location source control selects a location source for a mobile device. The mobile device can receive, from an application program, a request for determining a location of the mobile device. The mobile device can determine a first location estimate using a location subsystem of the mobile device. The mobile device can determine whether to provide the first location estimate as input to the application program, or to provide a second location estimate as input to the application program. The second location estimate can be an estimated location of the companion device and determined by the companion device.

Apparatus and methods are provided for peer-to-peer communication network and multi-channel operation over OFDMA. In novel aspect, the communication device sends a first frame to reserve a time period for one or more peer-to-peer services in a wireless communication network, establishes one or more sessions with one or more peer-to-peer communication devices in the time period reserved for a subset of the one or more peer-to-peer services, transmits a second frame allocating radio resource for a subset of communications devices of the one or more communications devices, and sends or receives one or more data frames to/from one or more peer-to-peer communication devices concurrently using OFDMA, wherein the one or more data frames are received during the reserved time period. In one embodiment, the communication device is non-AP. In another embodiment, the second frame indicates resource blocks allocated for each of the one or more peer-to-peer communication devices.

A movable device and a method for monitoring an operation cycle of an appliance are disclosed. For example, the movable device includes an operational detection component to receive operational feedback of the appliance, wherein the operational feedback comprises a vibration of the appliance and an audible signal of the appliance, a wireless interface to establish a wireless connection with a mobile endpoint device, a processor in communication with the operational detection component to determine when the appliance is in the operation cycle based upon the operational feedback and to generate a notification message that is sent to the mobile endpoint device when the appliance has completed the operation cycle, a housing enclosing the operation detection component, the wireless interface and the processor and a connection component coupled to the housing to removably couple the apparatus to the appliance.

A method and system are proposed for establishing a requested connection between a source node and a destination node in a telecommunications network. The system and method are described in relation to a 3GPP network, but are applicable to other types of networks. The method includes generating a source application identifier for the connection within the source node, retrieving a source node identifier for the source node and transmitting the source application identifier and the source node identifier to the destination to provide a source connection identifier for the requested connection between the source node and the destination node.

A method for use in establishing a packet data network, PDN, connection from a user equipment or UE, to a 3GPP core network via a non-3GPP access network. The method comprises receiving at the non-3GPP access network a request to establish the PDN connection; communicating with the 3GPP core network to establish a tunnel for the PDN connection between the non-3GPP access network and the 3GPP core network and to assign an IP address for the tunnel, which tunnel IP address is used subsequently by the non-3GPP access network to distinguish between the new PDN connection tunnel and at least one other such PDN connection tunnel already established for the UE, wherein the 3GPP core network is responsible for assigning the IP address, and sending address information from the non-3GPP access network to the 3GPP core network.

A method is described for operating a device in a wireless communication system. The device communicates with a base station using a subframe for the device only; detects, by the device, a problem with a connection between the device and the base station. The device starts a timer upon detecting the problem with the connection between the device and the base station. The device releases a restriction of using the subframe for the device only, if the timer expires. The problem with the connection between the device and the base station is associated with a radio link failure. The detection of a problem with the connection between the device and the base station comprises detecting consecutive out-of-sync indications.
