Digital cellular telecommunications system (Phase 2+) (GSM); Universal Mobile Telecommunications System (UMTS); LTE; Multimedia priority service feasibility study
|Publication Date:||1 May 2022|
This Technical Report (TR) presents the results of the feasibility study on Multimedia Priority Service. The intent of this feasibility study is to assess the ability of 3GPP specifications to meet high-level requirements identified for Multimedia Priority Service. This feasibility study consisted of a multi-step process, namely:
- Identify high-level requirements for Multimedia Priority Service.
- Determine relevant 3GPP specifications for Multimedia Priority Service.
- Perform a Gap Analysis to assess the ability of existing 3GPP specifications to meet the high-level Multimedia Priority Service requirements.
The present document also presents the results of the subsequent feasibility study on Multimedia Priority Service - Phase 2 for Rel-17 identifying new use cases and associated capabilities to account for current and anticipated MPS User needs for priority voice, data, and video communication capabilities. The feasibility study on Multimedia Priority Service - Phase 2 also identifies new potential requirements for the normative stage 1 requirements specified in TS 22.153.
Additional functionalities not documented in this TR are considered outside the scope of this TR. Such additional functionality may be on a network-wide basis, nation-wide basis or particular to a group of users..
The Multimedia Priority Service is intended to be utilised for both Voice and Data in the Packet-switched (PS) domain and the IP Multimedia Subsystem (IMS).
The Multimedia Priority Service is intended to interwork with external networks to provide an end-to-end service. Therefore, service interactions with external networks are considered within the scope of this document, although the specification of these interactions may be in other standards. If this occurs, a reference to that specification is made.
