Description
Technical field
The present invention relates to the mobile communication technology field, particularly the method and the device of managing subscriber location information in the EPS network.
Background technology
Along with science and technology development, communication network has been passed through from CS (Circuit Switched, circuit switching) network to the evolution that is carried as main PS (Packet Switched, packet switching) network with IP.Be carried as a key issue of carrying out telecommunication service in the main packet switching network with IP is to need to consider QoS (Quality of Service, service quality), to satisfy the requirement of user to communication quality.For example: the user carries out video call service, carries out effects such as needing to guarantee video is clear, smoothness in the process in business; In addition, be carried as the business that main packet switching network can also provide multiple class simultaneously, for example: web page browsing, file download, video request program etc. with IP.Like this, just require network must have the ability of distinguishing charging according to different business stream.At the demand, 3GPP (Third Generation PartnershipProject, third generation partner plan) has defined PCC (Policy Control and Charging, policy control and charging) framework.This framework is by detecting at the various flows that is carried as on the main packet switching network with I P, reaches to carry out purposes such as QoS control, charging, gate at Business Stream.After this, realize two-forty, the low transfer of data requirement that postpones and support multiple access technology in the main packet switching network in order to reach being carried as with IP, the system architecture of 3GPP from the PCC framework progressively to EPS (Evolved PacketSystem, evolved packet system) architecture evolution.
At present, in PCC R7 framework, defined the dependent event that some customer locations change, for example: SGSN (Serving GPRS Supporting Node, GPRS (General Packet Radio Service, GPRS) service support node) change incident, RAI (Routing Area Identify, Tracking Area Identifier) change incident.PCRF (Policy Control and Charging Rules Function, policy control and charging rule functions) can subscribe to these incidents by the Gx interface as required, like this after customer location changes, PCEF (Policy and Charging Enforcement Function, strategy and charge execution function) with the SGSN address after the customer position information change, the RAI value reports PCRF by the Gx interface, and PCRF will formulate corresponding PCC or QoS rule according to the information after changing.The Gx interface is primarily aimed at the GPRS access way.
Yet, after the grouping system architecture evolution, 3GPP inserts the framework of EPS network and inserts PCC R7 framework with the GPRS access way and compare bigger variation has taken place, for example: (the Mobility Management Entity of the MME in the framework of EPS network, Mobility Management Entity), SGW (Serving Gateway, gateway) replaced the function of the SGSN in the PCC R7 framework, unified PGW (Packet Data Network Gateway, packet data network gateway) has replaced the relevant gateway entity of access way traditional in the PCC R7 framework in the framework of EPS network.At this moment, the demand of PCEF after the customer position information that PCRF reports can not satisfy architecture evolution among the PCC R7.
Summary of the invention
In order to solve in the prior art, PCEF problem of customer position information demand in the EPS network architecture after the customer position information that PCRF reports can not satisfy architecture evolution among the PCC R7, the embodiment of the invention provides the method and the device of managing subscriber location information in a kind of EPS network.
The method of managing subscriber location information in a kind of EPS network that the embodiment of the invention provides comprises:
Obtain the described customer position information in the EPS network;
According to described customer position information, generate strategy.
The device of managing subscriber location information in a kind of EPS network that the embodiment of the invention provides comprises:
Information acquisition unit is obtained the described customer position information in the EPS network;

As shown in Figure 1, the method flow diagram of managing subscriber location information in a kind of EPS network that provides for the embodiment of the invention; This method comprises:
S101: obtain the described customer position information in the EPS network; Just PCRF obtains the information of the current position of user by policy execution entity.
S102:, generate strategy according to described customer position information.The customer position information that the PCRF basis gets access to is corresponding strategic decision-making or rules for quality of service for the user formulates.
As shown in Figure 2, the method flow diagram of managing subscriber location information in the another kind of EPS network that provides for the embodiment of the invention; This method comprises:
S201: subscribe to the described customer position information in the EPS network;
This step can be arranged to be obtained before the customer position information, is used for the incident that PCRF changes to PGW booking reader's positional information, for example: the incident that incident that the incident that MME changes, SGW change and TAI change.
S202: policy execution entity is obtained the described customer position information in the EPS network;
Policy control entity herein comprises PGW, SGW gateway; For example: under the EPS network architecture that the 3GPP based on GTP-base S5 inserts, when customer location changes, cause when MME, SGW, TAI etc. change, the incident that incident that the incident that MME changes, SGW change and TAI (Tracking Area Identify, trace regions sign) change sends to PGW by SGW with new MME address, SGW address and TAI value;
Under the EPS network architecture that the 3GPP based on PMIP-base S5 inserts, when customer location changes, cause when MME, SGW, TAI etc. change that the incident that incident that the incident that MME changes, SGW change and TAI change is directly obtained new MME address and TAI value by SGW from MME.
S203:PCRF receives the described customer position information in the EPS network that described policy execution entity reports;
Wherein, PCRF can obtain user position information according to above-mentioned PGW and SGW;
For example: under the EPS network architecture that the 3GPP based on GTP-base S5 inserts, PCRF can obtain new MME address, SGW address and TAI value by PGW;
Under the EPS network architecture that the 3GPP based on PMIP-base S5 inserts, PCRF can obtain new MME address, SGW address and TAI value by SGW.
S204: determine that described customer position information changes; After getting access to new MME address, SGW address and TAI value, MME address, SGW address and the TAI value of PCRF basis customer position information formerly and new MME address, SGW address and TAI value compare judgement.If customer position information changes, PCRF formulates corresponding strategy according to customer position information after changing; If customer position information does not change, PCRF does not change distributing policy.This step can be selected to judge according to the needs of actual conditions.
S205: formulate corresponding strategy according to customer position information after changing.
PCRF formulates corresponding strategy according to customer position information after changing; Promptly formulate corresponding strategy according to new address information.Wherein, described strategy comprises: policy control and charging regulation and rules for quality of service.Described customer position information comprises: Mobility Management Entity address, gateway address, TAI value.
