Abstract: A method for isolation in the CN domain of a network slice includes receiving a slice isolation policy and establishing a CN NSS isolation policy based on the slice isolation policy. When the CN NSS isolation policy includes a network resource isolation policy, the network resource isolation policy is mapped to a network resource allocation policy, a part of which relating to physical resources is sent to a network function management function (NFMF) and a part relating to virtual resources is sent to a network function virtualization management and orchestration function. When the NSS isolation policy includes an application level isolation policy, the application level isolation policy is mapped to an application level policy which is sent to the NFMF.

Abstract: A method, a device, an apparatus and a computer-readable storage medium for MAC address conflict detection. The method includes: in response to detecting a wireless local area network, transmitting, at a first device, a dummy MAC address of the first device to a second device in the wireless local area network, the dummy MAC address being different from a real MAC address of the first device; transmitting an address conflict detection request for the dummy MAC address to the second device; and in response to an address conflict detection response from the second device indicating that there is no conflict for the dummy MAC address, establishing a connection with the wireless local area network. The method may effectively protect privacy information for a user of a terminal device, while avoiding a MAC address conflict, such that the user can communicate in a secure network environment.

Abstract: Embodiments of the present disclosure relate to method and device for interworking between service function chain (i.e., service chain) domains In some embodiments, there is provided a communication method comprising: receiving, at a first logic node of a first service chain in a first domain, a first packet associated with a second service chain in a second domain; converting the first packet into a second packet comprising first interworking information between the first service chain and the second service chain, the first interworking information comprising a flag indicating that the second packet is an interworking packet, an address of the first logic node, a first flow identifier of the second packet, a first service path identifier of the second packet and metadata associated with the second service chain; transmitting the second packet to a second logic node in the second domain; and receiving from the second logic node a response to the metadata.
