Background technique

LTE (Long Term Evolution) is a long-term evolution of the UMTS (Universal Mobile Telecommunications System) technology standard developed by the 3GPP (The 3rd Generation Partnership Project).

The LTE introduces the S4SGSN (S4Serving GPRS Support Node, the service general packet radio service support node supporting the S4 interface) network element, which is used to provide services for the traditional 2G/3G wireless access, as shown in Figure 1, which includes the following Network element:

GSM EDGE Radio Access Network (GSM/EDGE Radio Access Network): The network element includes a BTS (Base Transceiver Station) and a Base Station Controller (BSC) to provide access for the terminal. Wireless resources.

UTRAN (UMTS Terrestrial Radio Access Network): The network element includes a NodeB (Node B) and an RNC (Radio Network Controller). Compared with GERAN, it can provide users with higher Up and down rate.

S4SGSN: A server that temporarily stores user data. It is responsible for managing and storing the UE (User Equipment) context (such as UE/user ID, mobility management status, user security parameters, etc.), and assigns temporary identifiers to users. The corresponding tracking area or network is responsible for authenticating the user of the UE; processing all non-access stratum messages between the S4SGSN and the UE.

SGW (Serving GW): The gateway is a user plane entity responsible for user plane data routing processing and terminating downlink data of the UE in idle state. It is also responsible for managing and storing the SAE (System Architecture Evolution) bearer context of the UE, such as IP (Internet Protocol) bearer service parameters and network internal roads. By information and so on. It is the anchor point of the internal user plane of the 3GPP (The 3rd Generation Partnership Project) system. One user can only have one Serving GW at a time.

HLR (Home Location Register): saves the user's authentication and subscription information, dynamically updates the location information of the user, and can provide the information of the user to the S4SGSN network element.

HSS (Home Subscriber Server): A new network element for the LTE network, which is used to replace the HLR network element and has the same functional capabilities as the HLR.

In the LTE network construction process, there are a large number of traditional 2G (second generation communication system) / 3G (third generation communication system) users, based on various factors, in reality, these user subscription data cannot be migrated from HLR to new at the same time. The HSS network element, such that there is a part of the user's subscription data in the HLR, and some in the HSS situation; after these users access the S4SGSN, the S4SGSN needs to know the location of the user's subscription data when requesting the user's subscription data. In order to solve this problem, the current method is to statically configure the location information of the subscription data for the user in advance on the S4SGSN, for example, on the HLR or on the HSS, and the S4SGSN can query the location and initiate the acquisition request according to the configuration. But this approach has at least the following problems:

1. The amount of data to be configured is huge, resulting in a large workload and error-prone;

2. The user's subscription data changes frequently. For example, today's user's subscription data is on the HLR, but the next time or tomorrow will be migrated to the new HSS. In this case, the configuration should be updated in time, otherwise it will lead to errors. The contract data of the user is not obtained, so the maintenance cost and the difficulty are great.
