摘要

A method and apparatus is provided for determining whether to transmit network slice selection assistance information to a network as part of radio connection establishment signaling. An indication from the network is received as to whether the network slice selection assistance information is required. The transmission of the network slice selection assistance information is activated when the information is determined to be required, or deactivated when the information is determined to not be required. The access stratum layer is informed by a non-access stratum layer about the network slice selection assistance information during an initiation of service request procedure when the user equipment is in a connection management idle state, and the network slice selection assistance information is transmitted in the radio connection establishment signaling to the network when the transmission of the information is activated.

說明書

In some instances it has been deemed beneficial to create the possibility for multiple virtual networks, that can operate independently, but which function within the same physical hardware. This can be called network slicing. In some instances, different slices may be configured and maintained in order to support different application, services, and/or in order to support other arrangements that may benefit from a form of separation from the other slices, where each slice may potentially have an alternative overall purpose. In essence, each slice is similar to a separate and distinct virtual network, where each particular network slice can have its own architecture, as well as have its own separate provision management and security, where each network slice can be tailored to take into account support, which is better adapted for the corresponding purpose associated with a particular slice.
