Embodiments of this application provide a communication method, an apparatus, and a system. The method includes: A proxy base station receives a MSG1 from a user equipment. The proxy base station sends a MSG2 to the user equipment in response to the MSG1, where the MSG2 includes a timing advance, and the timing advance is determined based on at least one of an internal processing delay of a signal extension system and a delay between the signal extension system and a signal source base station.

The invention relates to a method for discovering a home agent serving a mobile node upon the mobile node changing its mobility management scheme in a packet-switched network and the implementation of such method in a mobile node or home agent. In order to propose a home agent discover scheme that maintains session continuity in a seamless manner upon a mobile node changing its mobility management scheme, a mobile node comprises information on its location prior to changing the mobility management scheme to one of the first signaling messages transmitted upon changing the mobility management scheme (home agent discovery message). The receiving node uses this information to identify the home agent serving the mobile node or to provide a hint to the home agent where the mobile node is registered in a response message to the mobile node.

Methods, systems, and non-transitory computer readable media for validating a simulated component of a communication network using real traffic. More particularly, a simulator instantiates a simulation environment that includes a base station module, a user equipment (UE) module, and a simulated communication link therebetween. Real traffic generated by a non-simulated UE is sent to a proxy that routes the traffic to the UE module. As a result, test software instated in the simulation environment can be validated using traffic generated by a non-simulated UE.

A method of controlling communications within a wireless communications network is provided. The method comprises receiving, at a first infrastructure equipment acting as a donor node connected to a core network part of a wireless communications network, signals representing data from one or more others of infrastructure equipment, the data having been received at the one or more others of the infrastructure equipment from one or more communications devices or from other infrastructure equipment, and transmitting, by the first infrastructure equipment, the data from the one or more others of the infrastructure equipment to the core network part of the wireless communications network. At least one of the infrastructure equipment uses at least one spectral efficiency enhancing technique to receive the signals, the at least one spectral efficiency enhancing technique allowing the at least one infrastructure equipment to receive the signals in the backhaul communications link.

Embodiments described herein relate to methods and apparatuses for enabling remote management of a profile in an identity module in an NB-IoT device. A proxy server is configured with access to a database of one or more external identifiers associated with one or more respective NB-IoT devices, wherein the one or more external identifiers are used to address the respective one or more NB-IoT devices via an exposure function in a core network. A method in the proxy server comprises receiving a request to deliver a triggering message to the NB-IoT device, wherein the request comprises a device identifier; determining an external identifier based on the received device identifier; and delivering the triggering message to the NB-IoT device using the external identifier.

Embodiments of the present disclosure provide methods and apparatuses for flow control. A method at a service communication proxy (SCP) comprises creating a flow table entry including a match field and an instruction field. The method further comprises applying the flow table entry to match and process a service request from a network function (NF) consumer, wherein the service request may be to be served by a NF producer.

A cellular data communication network includes a BBU connected to a UPF by an IP network. A first translation module translates GFP packets into IP packets transmitted over the IP network. A second translation module translates the IP packets back into IP packets and forwards the IP packets to the UPF. A PFCP proxy intercepts control packets of the UPF. Information snooped by the PFCP proxy is provided to a routing/SDN controller that programs the translation modules and a routing module to perform routing of packets in bypass of the UPF.

Various arrangements for managing network channels are presented. A backend system may receive data from one or more data sources. The backend system may determine, based at least in part on the data received from the one or more data sources, a triggering event and a location related to the triggering event. The backend system may transmit, to an unmanned aerial vehicle (UAV), first location data associated with the location related to the triggering event. The backend system can receive, from the UAV, network congestion information associated with a connection between one or more devices and the UAV. Based at least in part on the network congestion information, the backend system may send second location data to the UAV.

A method for performing service authorization for private networks based on an enhanced PLMN identifier. The method includes receiving an attach request from a user equipment device (UE) via a private network, where the attach request includes an international mobile subscriber identity value (IMSI). The method further includes determining, based on the IMSI, an organization identifier and a token associated with the private network, where the token is included in an enhanced PLMN for granting the UE access to resources in the private network. The method further includes sending the token to the UE and a network proxy within the private network.

The Wireless-Node-Hub invention is a dual device invention for enabling wired sensor platforms to become wireless without the need of changing the sensors or the base unit(s) to which they are connected; but rather rely on modules which plug into the sensors and base units which enable the normally wired communication to become now wireless.
