A data transmission method and a first electronic device are provided. The data transmission method includes: sending a first request to a second electronic device in a case that a first electronic device accesses a network hotspot of the second electronic device; receiving a first response of the network hotspot that is fed back by the second electronic device in response to the first request. The first response includes the hotspot information. The data transmission method further includes when the hotspot information does not include a Domain Name Service (DNS) parameter of the network hotspot, configuring a data network route to transmit first data, and configuring a target policy route to transmit second data. The second data is data transmitted between the first electronic device and the network hotspot.

Methods and systems are disclosed for configuring a network consisting of an IP Policy Management (IPPM) service and a plurality of distributed network devices supporting DHCP and other service roles wherein network devices are discovered by the IPPM service and the configuration for each of the network devices is determined by the selection of a policy, wherein the policy is made up of a plurality of rules specific to the service roles and capabilities of the network devices, and the configuration of each of the network devices is deployed via the network to the network devices.

An apparatus in a computer network system extracts network traffic metadata related to a client computing device of a local network. The network traffic metadata is required by a device fingerprinting process. In response to detecting a multicast DNS (mDNS) packet query in the network traffic metadata, the apparatus collects an mDNS hostname related to the client computing device from the mDNS packet query. In response to determining, at a first point in time, that a dynamic host configuration protocol (DHCP) hostname related to the client computing device is unavailable in the network traffic metadata, the apparatus assigns the mDNS hostname to the client computing device.

An address management method, system, and device to avoid a problem that a same Internet Protocol (IP) address is assigned to different packet data unit (PDU) sessions and to effectively use IP addresses in an address pool. The method includes: obtaining, by a session management network element, an identifier of a user plane function network element serving a terminal and session information of the terminal; determining, by the session management network element based on the identifier of the user plane function network element and the session information, an address pool identifier corresponding to the session; sending, by the session management network element, the address pool identifier to a server, where the address pool identifier is used to assign an IP address to the session; and receiving, by the session management network element from the server, the IP address corresponding to the session.

When a failed connection is detected from a first radio unit (RU) to the cellular site router (CSR), activation of an existing backup cabled connection from the first RU to the CSR through a cabled connection between the first RU and a second RU of the cellular telecommunications tower may be performed. In one example, a first RU and second RU each have two physical network ports. The activation of the existing backup cabled connection from the first RU, via the second RU, to the CSR may include causing the first RU to enter from a normal operating mode into an Open Radio Access Network (O-RAN) cascade operating mode to attempt to attain network connectivity for the first RU using the second physical network port of the first RU.

Embodiments enable seamless Wi-Fi roaming by providing a user with a single username that is associated with a set of resources in the seamless network that includes different Wi-Fi networks (e.g., Wi-Fi networks with different domain names). As a user travels from a first access point in a first Wi-Fi network to a second access point in a second Wi-Fi network within the seamless network, network elements in the seamless network may recognize the user's single username as an already established session (e.g., with the first access point) and direct traffic accordingly to the second access point. Embodiments also satisfy business requirements by updating accounting data accordingly by indicating that the user accessed the seamless network from the first Wi-Fi network. Embodiments allow a user roaming on the seamless network to experience the policies and network requirements associated with the Wi-Fi domain of the second access point.

Embodiments of a device and method are disclosed. In an embodiment, a method of automatic network service initiation involves pairing a first network device of a network service block (NSB) with an installer device at a customer site, at the first network device of the NSB, obtaining first network service configuration information from the installer device, performing automatic network service initiation of the first network device of the NSB based on the first network service configuration information, at a second network device of the NSB that is connected with the first network device of the NSB, obtaining address information of a cloud server from the first network device of the NSB, at the second network device of the NSB, obtaining second network service configuration information from the cloud server based on the address information, and performing automatic network service initiation of the second network device of the NSB based on the second network service configuration information.
