Study on Network Slice Capability Exposure for Application Layer Enablement
The study identifies the SA1 requirements and potential vertical requirements of network slice capability exposure that have yet to be realized, and proposes application architecture aspects solutions and enhancements to SEAL. Based on any gaps found between requirements and existing capabilities, the present document includes: identification of key issues, solutions, corresponding evaluations and conclusions to ensure the efficient network slice capability exposure.
The study takes into consideration the SEAL architecture specified in 3GPP TS 23.434 [2], network slicing related architecture and services(such as services of NEF) specified in 3GPP TS 23.501 [3] and 3GPP TS 23.502 [4], network slicing management capability provisioning and architecture specified in 3GPP TS 28.531 [5] and 3GPP TS 28.533 [6], requirements specified in TS 22.261 [7].
