A communications method, device, and system for solving the connection and communications efficiency problem due to the presence of a large number of cells. The method comprises: a first local controller determines that a user equipment needs to establish a data bearer; data bearer configuration information for transmitting user data is generated; the data bearer configuration information is transmitted to a first local gateway and/or at least a first small base station, so that the network element entity that has received the data bearer configuration information establishes a data transmission channel according to the data bearer configuration information, the user equipment belonging to the first local controller and the first local gateway, the first small base station providing services to the user equipment.

Systems, methods, apparatuses, and computer program products for reference signal adaptation based on incoming user mobility information are provided. One method includes receiving, by a target base station, a request to begin transmitting reference signals for mobility measurements. The request may be received from a source base station serving a user equipment. In addition, the request may be received when a handover of the user equipment is impending.

A network device with wireless access point capabilities selectively captures PDUs detected on an instrumented interface(s) to capture those of one or more types/subtypes “of interest.” PDU types/subtypes that network device interface(s) has been instrumented to treat as “of interest” include those transmitted during a device's initial network activity during startup or attempted establishment of a wireless network connection. The interface(s) instrumented for targeted PDU capture can include wireless and/or wired (e.g., Ethernet) interfaces that are received on raw sockets so that each header type of a captured PDU is written to the PDU capture file. Prior to upload of a PDU capture file to a system from which it can be retrieved for analysis, the network device adds network metadata to the file based on context of the environment in which the network device operates. The network metadata can include IP address and/or network topology information determined at runtime.

A 5G communication system includes at least one visited network slice; a home network slice; and a bridge entity. The at least one visited network slice comprises a visited radio access network (RAN) entity. The home network slice comprises a home Access and Mobility Management Function (AMF) entity. The bridge entity coupled between the visited RAN entity and the home AMF entity, wherein the bridge entity is configured to route a registration request message of a roaming user equipment (UE) received from the visited RAN entity to the home AMF entity.

A system and method is disclosed of extracting information from real-time network packet data to analyze connectivity data for client devices in a network. The method includes: detecting when client devices initiate a connectivity event; after detecting a connectivity event, waiting a period of time for the client device to either reach or fail to reach a network connected state; after waiting a period of time, recording connectivity event information; and sending the recorded connectivity event information to an analytics system for network incident and/or network congestion analysis.

The invention relates to a method, network ad network entity for establishing a communication session between a calling subscriber residing in a first Visited IMS network and a called subscriber roaming in a second Visited IMS network. The method includes routing a first Invite request for the communication session via a media path extending from the first Visited IMS network via a Home IMS network of the called subscriber to the second Visited IMS network, and establishing the communication session. The method further includes inserting an additional IMS network entity, residing in the second Visited IMS network, in the part of the media path extending from the first Visited IMS network to the Home IMS network of the called subscriber and removing the Home IMS network of the called subscriber from the media path.

Communications control in response to establishment of a multi-access PDN connection or with rejection of establishment of a multi-access PDN connection is performed based on a response to a PDN connectivity establishment request from a terminal device. This provides a method of communication control and the like in response to a multi-access PDN connectivity establishment request from the terminal device.
