Abstract
The invention provides a method and a system for acquiring user contracting data. The GPRS (general packet radio service) network of a system comprises an HLR (home location register), and an EPS (evolved packet system) network comprises an SGSN (service GPRS support node) and an HSS (home subscriber server), wherein both the HLR and the HSS are user contacting data memories and are directly connected; the SGSN is used for sending a user operation request of a user to any one of the two user contacting data memories when a 2G (2nd generation) user or a 3G (3rd generation) user or an LTE (long term evolution) user is accessed and acquiring the user contacting data of the user from the user contacting data memory receiving the transmitted user operation request; and the contacting data memory is used for transmitting the user operation request to the other user contacting data memory when the user is judged to be not managed by per se after the user operation request is received from the SGSN. The invention can quickly acquire the user contacting data on the premise of simplifying system operations when the 2G/3G user and the LTE user are uniformly operated.
Description
Technical field
The present invention relates to wireless packet domain and evolution territory in the mobile communcations system, relate in particular to a kind of method and system of obtaining user contracting data.
Background technology
As shown in Figure 1, third generation partner program (3rd Generation Partnership Project, be called for short 3GPP) at second generation mobile communication (2rd Generation, be called for short 2G)/3G (Third Generation) Moblie (3rd Generation, abbreviation 3G) portable terminal has defined a network architecture when inserting, be GPRS (General Packet Radio Service is called for short GPRS) network, in this network, comprise following network element:
The GSM EDGE Radio Access Network network is GERAN (GSM/EDGE Radio AccessNetwork, wherein, global mobile communication GSM full name is Global System for Mobilecommunication, enhanced data rates for gsm evolution technology EDGE full name is Enhanced DataRate for GSM Evolution), be also referred to as the 2G/2.5G Radio Access Network.
The global system for mobile communications terrestrial access network is UTRAN (UMTS TerrestrialRadio Access Network, wherein, the full name of global system for mobile communications UMTS is UniversalMobile Telecommunications System), be also referred to as the 3G Radio Access Network.
Gateway GPRS Support Node is GGSN (Gateway GPRS Support Node, wherein GPRS GPRS full name is General Packet Radio Service), be to be responsible for user equipment (UE) (User Equipment) accessing group data net (Packet Data Network in the GPRS network, abbreviation PDN) gateway, distributing user IP address is the user's anchor point in the GPRS network.
Serving GPRS Support Node is the mobile management node that SGSN (Serving GPRS Support Node) is a portable terminal when UTRAN and GERAN insert, the server of interim storaging user data, the context of being in charge of and storing UE is (such as the user ID of UE, mobility management states, user security parameters etc.), for the user distributes temporary mark, be to be responsible for this user is carried out authentication when UE quarters at this Routing Area or this network.
Attaching position register is HLR (Home Location Register), is used for the permanent storage user contracting data in the 2G/3G network.
To be called the grouping system of evolution be EPS (Evolved PacketSystem) in the system of mobile wireless network of future generation in the Long Term Evolution of 3GPP definition (Long Term Evolution the is called for short LTE) system, wherein comprised following network element:
The wireless access network of evolution is E-RAN (Evolved Radio Access Network), and higher up-downgoing speed can be provided, lower transmission delay and reliable more wireless transmission.The network element that comprises among the E-RAN is that the Node B of evolution is eNodeB (Evolved NodeB), for the access of terminal provides Radio Resource.
Home subscriber server is HSS (Home Subscriber Server), is used for the permanent storage user contracting data in the EPS network.
Packet Data Network is PDN (Packet Data Network), for the user provides professional network.
The packet-based core networks of evolution (E-Packet Core) have improved lower delay, and allow more wireless access system to insert, and have comprised following network element:
Mobile management entity is that MME (Mobility Management Entity) is used for the chain of command functional entity, the server of interim storaging user data, be in charge of and store the UE context (such as the user ID of UE, mobility management states, user security parameters etc.), for the user distributes temporary mark, be to be responsible for this user is carried out authentication when UE quarters at this tracing area or this network; Handle all non-access layer informations between MME and the UE; Triggering is in the paging of SAE.
Gateway is Serving GW (Gateway), and this gateway is a user entity, is responsible for the user face data route and handles, and termination is in the downlink data of the UE of idle condition.The System Architecture Evolution of management and storage UE is SAE (System Architecture Evolution) carrying (bearer) context, such as IP bearer service parameter and network internal routing iinformation etc.Gateway is the anchor point of 3GPP internal system user face, and a user can only have a gateway a moment.
Packet data network gateway is PDN GW, is to be responsible for the gateway that UE inserts PDN, and distributing user IP address is the mobility anchor point of 3GPP and non-3GPP connecting system simultaneously.The user can insert a plurality of packet data network gateways at synchronization.
Strategy and to add up to the expense regulation function entity is PCRF (Policy and Charging RuleFunctionality), this functional entity are Qos (Quality of Service) rule and charging regulation according to the service quality that the configuration information of business information and user signing contract information and operator produces the control user data delivery mainly.This functional entity also can be controlled the foundation and the release of carrying in the Access Network.
Physically, gateway Serving GW and packet data network gateway PDN GW may unify.
In the EPS network, also still have SGSN, but this SGSN is different with SGSN in the original GPRS network.The SGSN that is in the original GPRS network (being the 2G/3G network) is called as Gn/Gp SGSN, and Gn/Gp SGSN can only link to each other with the PDN GW of GGSN or embedded GGSN function by the Gn/Gp interface.The SGSN that is in the EPS network is called as S3/S4SGSN, and S3/S4SGSN can link to each other with SGW by the S3/S4 mouth, links to each other with GGSN by the Gn/Gp mouth.Gn/Gp SGSN can only link to each other with 2G/3G user's subscription data register HLR in addition; And S3/S4 SGSN both can link to each other with 2G/3G user's subscription data register HLR, also can link to each other with the subscription data server HSS that supports LTE user.
The system framework of present 3GPP protocol definition, in actual operation, just brought problem: if operator uses S3/S4 SGSN to finish the access of GERAN and UTRAN, when a user inserts, because S3/S4 SGSN does not know that this user is a pure 2G/3G user or supports the LTE user that 2G/3G inserts, and can't determine from HLR still to be that the HSS place obtains user contracting data.
This moment, possible a kind of solution was that requirement operator is when operation, 2G/3G user and LTE user's strictness are distinguished, be that 2G/3G user and LTE user use the diverse section, if S3/S4SGSN this moment finds that the user is the user who belongs to 2G/3G user number section, just to HLR request user contracting data; If find that the user is the user who belongs to LTE user number section, just to HSS request user contracting data.But this 2G/3G user and LTE user use the diverse section, be very disagreeableness in actual operation, if promptly this user is originally pure 2G/3G user, want to become LTE user now, just must change Subscriber Number, this is the problem that a lot of users are unwilling to face, and also is that operator does not want the scheme that adopts.
Also having a kind of possible solution is when each user inserts, S3/S4 SGSN attempts, promptly send request to HLR or HSS earlier,, send request to another one HSS or HLR again if do not return when failing because finding this user among HLR or the HSS.It is to address this problem that this each user inserts the mode of attempting.But this solution can be brought S3/S4 SGSN and HLR, a large amount of failures when HSS is mutual, and influences network operation.
