The present application is the U.S. national phase of PCT Application No. PCT/CN2017/080601 filed on Apr. 14, 2017, which claims a priority of the Chinese patent application 201610237638.6 filed on Apr. 15, 2016, which are incorporated herein by reference in their entirety.
The present disclosure relates to the field of communication technology, in particular to a Service Provider Identifier (SP-ID) indication method, an SP-ID indication device, a User Equipment (UE), and an access device.
MulteFire is an uplink transmission method newly defined on the basis of a Licensed-Assisted Access (LAA) downlink transmission method in a Long Term Evolution (LTE) Release 13 (R13), and it may operate individually at an unlicensed frequency spectrum (i.e., stand-alone LTE-U). The MulteFire may support one or both of two network modes (or network services), i.e., a Public Land Mobile Network (PLMN) access mode and a Neutral Host Network (NHN) access mode.
In order to support a plurality of service providers in a MulteFire network (e.g., an NHN network), i.e., to enable the plurality of service providers to provide services through the MulteFire network, Participating Service Provider Identity (PSP-IDs) have been introduced. The PSP-IDs are adopted to indicate different PSPs. For example, a plurality of PSP-IDs may be adopted to indicate a plurality of PSPs supported by a UE. However, the current research in the communication field focuses on how to report the PSP-IDs at a UE side, i.e., there is an urgent need to provide a scheme for reporting the PSP-IDs by the UE.
