Description

A method, system and service platform for a service platform to obtain a user's mobile phone number

technical field

The invention relates to a method for a service platform to obtain a user's mobile phone number under a strategy and billing control framework, and belongs to the field of communication networks.

Background technique

PCC (Policy and Charging Control, Policy and Charging Control) architecture is the QoS (Quality of Service, Quality of Service) guarantee mechanism of the next-generation core network evolution SAE (System Architecture Evolution, System Architecture Evolution) project. Figure 1 shows the network architecture of the end-to-end service quality assurance solution.

Among them, PCRF (Policy and ChargingRulesFunction, policy and charging rule function device) is the centralized decision-making point of the QoS rules of this architecture, and the input of its decision comes from AF (ApplicationFunction, application function device, which is usually implemented by the service platform, and in the IMS network by In the service information (service flow description, service flow bandwidth requirement, service flow media type, service ID, etc.), user ID and SPR (SubscriptionProfileRepository, user attribute storage) provided by the Rx interface of the access domain (implemented by the P-CSCF of the access domain) Included user subscription information and locally configured operator policies.

Among them, in the 3GPP network, the PCRF generates the authorized QoS rules and sends them to the policy and charging enforcement functional entity PCEF (Policy and Charging Enforcement Fucntion, implemented by P-GW under LTE, and implemented by GGSN under 2G/3G), and PCEF according to Authorize QoS rules for policy enforcement; in non-3GPP networks (such as WLAN, Wimax), PCRF generates authorized QoS rules and sends them to BBERF (BearingBindingandEventReportFunction, bearer binding and event reporting functional entity), and BBERF executes according to authorized QoS rules Policy enforcement.

Chinese patent application number 20071015713.3, publication date 2009-04-29, invention name: "NAT Technology Implementation Method in PCC Architecture, PCRF and AF" discloses a business process based on PCC architecture, wherein, in UE (UserEquipment , when the user terminal) initially attaches to the network, it is necessary to establish an IP-CAN (IP-Connectivity Access Network, IP connection access network) session between the user terminal and the network side, and the UE carries out its own business based on the established IP-CAN session. The disclosed process is shown in Figure 2 and Figure 3, where the process in Figure 2 is briefly described as follows:

Steps 301 to 302: PCEF receives the IP-CAN session establishment request message (Gx interface, adopting Diameter protocol) sent by UE, and requests PCRF to issue the default PCC rules of the UE; among them, the session between PCEF and PCRF for session one.

In the above process, it is required to provide the address of the UE to the PCRF after step 302 or step 310 (not shown in the figure, used when the PCEF cannot obtain the address of the UE in step 302), wherein, in step 302 It also needs to carry the user identity (IMSI or MSISDN) of the UE.

Among them, the IP-CAN session established by the process shown in Figure 2 establishes a default bearer between the UE and the PCEF. Based on the default bearer established in session 1, the UE can initiate a service request, such as initiating a login request or an IMSInvite request etc. In order to control the services to be carried out by the UE, it is necessary to formulate appropriate PCC rules for the services requested by the UE.

Fig. 3 is a flow chart of service control for UE under the PCC architecture. According to Fig. 3, the process is described as follows:

Steps 401-403: After the AF is triggered, define the service information of the UE, send the service information of the UE to the PCRF through an Rx interface message (AAR message), and initiate a session between the AF and the PCRF. The service information of the UE may include the UE's network address, network identifier, service data flow description information, and the like. Wherein, the session between the AF and the PCRF is called session two.

Step 404: After the PCRF receives the AAR message from the AF, it stores the service information of the UE in it. If the PCRF does not store the user subscription data, it executes step 405; otherwise, it executes step 407.

Steps 405-406: PCRF sends a request message requesting user subscription data to SPR; SPR returns user subscription data to PCRF after receiving the request message.

Steps 407-409: PCRF binds session 1 and session 2 according to the network address of UE sent by AF in session 2 and the network address of UE received from PCEF in session 1. After the binding is successful, PCRF The PCC rules can be formulated and stored, and the PCC rules can be delivered to the PCEF.

In addition, according to the existing technology, usually a service hopes to identify the user in a certain way. Considering the uniqueness of the mobile phone number, the operator generally uses the user's mobile phone number as the best user identification method. For this reason, the service platform needs Obtain the mobile phone number of the user.

Among them, in the existing PS domain network environment, the operator usually sets a specific APN (AccessPointName, access point, such as CMWAP), and under this APN, the IP route between the UE and the server is inserted into the network via a mobile phone number. element (for example, WAP gateway), and this network element inserts the mobile phone number of the user in the request initiated by the UE to the service platform, wherein, Fig. 4 is a network schematic diagram of obtaining the mobile phone number of the user under the environment of the PS domain in the prior art;

As shown in Figure 4, when the UE opens the connection to CMWAPAPN, the communication between the UE and the server in the PDN (Public Data Network, public data network) network passes through the GGSN and the WAP gateway, and the WAP gateway forwards the uplink from the UE to the PDN direction on behalf of the UE. During message, for specific message protocol (limited as HTTP and WAP protocol, insert mobile phone number at the head of the message of each above-mentioned agreement.

Moreover, the insertion function of the mobile phone number inserted into the network element can be implemented in a proxy mode, or in a routing mode (at this time, the network element is a routing device, which has a deep analysis function and can insert data in the forwarded IP packet).

The above solutions are usually only open to the operator's own business. The user does not need to input or perceive the user's mobile phone number. The service platform (especially the operator's own business platform) can make full use of the user's mobile phone account to send Deduction of fees and in-depth user portraits are carried out during the user's business use.

But there is following shortcoming in above-mentioned prior art:

1. It can only insert the user's mobile phone number into a few text-type protocol (such as HTTP protocol) messages, and cannot be compatible with other protocols, such as binary private protocols, which are very important for the relatively small bandwidth of mobile communication networks; For example, the SIP protocol is text-based, and a single message usually exceeds 1K bytes, while the same message in binary design only needs 40 bytes, and the delay difference introduced by this is as much as 25 times, and the absolute difference can reach 250ms. It is difficult to accept today's increasing emphasis on user-perceived quality.

2. Because the role of each message cannot be distinguished, the WAP gateway can only insert the user's mobile phone number into all messages from the mobile phone to a specific (realized by the whitelist function of the WAP gateway) service platform, which brings considerable delay;

3. In order to realize the mobile phone number insertion function, the WAP gateway needs the protocol analysis function. The above-mentioned analysis process introduces a lot of time delay, which deteriorates the user experience. At the same time, the rapid development of the mobile Internet also requires the WAP gateway to continue to expand, which introduces a lot of costs. overhead.
