Although this method violates the operator's desire for a smooth transition and minimal impact on the existing network, even so, due to various operational reasons, some users still cannot be cut over to the HSS

Embodiment 1

[0044] like figure 2 As shown, this embodiment is in figure 1 An interface Sx is added between the HLR and the HSS. Sx is an interface symbol, and the type of this interface can be defined as a Gr interface. And in the HSS of the EPC, the routing redirection function of the HLR of 2G / 3G is added. In the text, such an HSS is also called EPC HSS / FNR (Flexible Number Routing, referred to as FNR, which is translated as routing redirection in the text).

[0045] like image 3 As shown, three kinds of user information are stored in the EPC HSS / FNR of this embodiment:

[0046] The newly added EPS users store CS and Evolved Packet Core (EPC: EvolvedPacket Core) data of such users, and store PS data for backward compatibility;

[0047] For 2G / 3G upgrade users, store CS and EPC data of such users, and store PS data for backward compatibility;

[0048] Unmigrated 2G / 3G users store the identification information of the 2G / 3G users and the routing information of the corresponding HLR ...

Embodiment 2

[0060] The system architecture based on this embodiment is also as figure 2 As shown, an interface Sx is added between the HLR and the HSS, and the EPC HSS / FNR also needs to save the identification information of the 2G / 3G user and the routing information of the corresponding HLR.

[0061] The scenario of this embodiment is that a 2G / 3G user uses an LTE mobile phone to access the EPC from the e-UTRAN. During the attachment process or post-attachment service request process and location update message, the MME sends a corresponding query user information request to the EPCHSS / FNR. After receiving the request, the EPC HSS / FNR finds the The corresponding HLR sends the request to the HLR through the interface Sx, the HLR processes the request after receiving the request, and sends the information to be returned to the EPCHSS / FNR, and the EPC HSS / FNR sends it to the MME. Likewise, the above-mentioned request for querying user information may be an authentication request, a locati...

Abstract

The invention relates to routing redirection method and system for user information query, which are applied to a scene for accessing a 2G / 3G (second generation / third generation) user into an EPC (Evolved Packet Core) system by a GERAN (Gsm Edge Radio Access Network) or UTRAN (Umts Terrestrial Radio Access Network). An SGSN (Serving GPS Support Node) passing through when the 2G / 3G user is accessed transmits request message for querying user information, identification information carrying the user and the routing information of the SGSN to an HSS (HomeSubscriber Server) of an EPC; after the HSS receives the information, the user is judged to be an unmigrated 2G or 3G user and the request message contains the routing information of the SGSN, an HLR (Home Location Register) for storing the user information is queried according to the identification information of the user, and the request message is forwarded to the HLR; and after receiving the request message transmitted by the HSS, the HLR processes the request message and transmits user information needing to be returned to the SGSN. The invention ensures that the 2G / 3G user can be also accessed into an EPS (Evolved Packet System) under the condition of not carrying out data migration and develop businesses.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a route redirection method and system for user information query of 2G / 3G users. Background technique [0002] In related technologies, figure 1 is a schematic diagram of an architecture of an evolved packet system (Evolved Packet System, referred to as EPS), such as figure 1 As shown, the EPS of the 3rd Generation Partnership Project (referred to as 3GPP) consists of an Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN), a mobile management unit (Mobility Management Entity, referred to as MME), serving gateway (Serving Gateway, referred to as S-GW), packet data network gateway (Packet DataNetwork Gateway, referred to as P-GW or PDN GW), home subscriber server (HomeSubscriber Server, referred to as HSS), Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF for short) and othe...
