"Technical stuff." What is the difference between the user database HSS in LTE networks and the HLR of traditional 2g/3g? Can I combine networking?

EPS HSS and HLR are respectively responsible for 4G user data and 2G/3G user data storage, the two main differences are:

(1) different stored data, including user dynamic information and static contract data, HSS storage user 4G dynamic information (such as user 4G location information), the user has 4G static contract data (such as User 4G APN and QoS signing data), HLR store users 2g/3g dynamic information (such as user 2g/ 3G location information), as well as user 2g/3g static contract data (such as telecom service contract information, supplementary business business contract information, 2G/3G APN and QoS signing data).

(2) The two belong to different grids, external interface, protocol and bearer mode, EPS-HSS through S6A, s6d interface and Mme, S4 SGSN connected, using diameter protocol, based on IP bearer, HLR through the C/D interface, GR interface and MSC/VLR, SGSN connected, Use the map protocol, based on TDM hosting.

EPS HSS and HLR are responsible for the user data storage, intelligent similar in the network, and the high coincidence rate of storage information, can be divided into a separate or integrated network. EPS HSS and HLR Convergence Network can reduce the multi-point opening, data inconsistency, authentication weight synchronization, data redundancy, complex network configuration and other problems, while reducing the equipment occupies a few energy consumption, is conducive to the future evolution of the network and development, the proposed integration network.
