A signaling compression method for MCPTT trunking communication system based on carrier aggregated broadband system
Ziguang Niu, Li Hai, Chen Xu · 2017
This paper proposes a novel signaling compression method to meet the requirement of the MCPTT call service under limited physical carrier capacity of carrier aggregated broadband system. In addition, we design an architecture that hosts compression proxies on both the user and network side without the modification of core network of LTE system. The signaling compression method has been implemented on different platforms to verify the feasibility of our method. The test results show that the method meet the requirement of call services in MCPTT.
