Background technique

With the rapid development of mobile communication technologies and the increasing demand for high-speed data services, high-speed packet data (HRPD) networks are evolving. In order to achieve interoperability with an Enhanced Universal Terrestrial Radio Access Network (E-UTRAN), the HRPD evolves into an EHRPD (Evolved High Rate Packet Data).

1 is a schematic structural diagram of interoperability between eHRPD and E-UTRAN in the prior art. As shown in FIG. 1, the network element in the E-UTRAN network includes: Mobility Management Entity (MME), packet data.

The network elements in the eHRPD network include: an evolved access network (eAN, Evolved Access Network), an evolved packet control function (ePCF, Evolved Packet Control Function), a high speed packet data service gateway (HSGW, HRPD Serving Gateway), and the like; eHRPD The enhancement of the original HRPD wireless and packet core network brings a series of new features. For example, eHRPD also includes a Packet Data Network (PDN) for support, bearer multiplexing, and network-side initiated quality of service ( QoS (Quality of Service), single access point name multi-packet data network connection (MUPSAP, Multiple PDN Connections to ASingle APN). After the PGW obtains the user's location, it can perform specific services based on the user's location information, such as assigning a specific address.

In the current eHRPD network, the PGW acquires the location information of the terminal, and first needs to send the terminal location information to the HSGW through the A11 signaling via the PCF, and then the HSGW forwards the PCR location to the PCRF through the diagnostic signaling, and finally the PCRF can pass the diagnostic signaling. Reach the PGW. Therefore, in the prior art, the PGW acquires the location information of the terminal, and not only needs to deploy the PCRF, but also needs the HSGW support policy control (PCC, Policy Control Charging) function, and under the premise that both the PCRF and the PGW subscribe to the terminal location change event push, Network elements need to be acquired through multiple signaling interactions, which greatly increases the complexity of the PGW acquiring terminal location information.

detailed description

2 is a schematic flowchart of a method for acquiring location information of a terminal by using a PGW. As shown in FIG. 2, the process of acquiring location information of the terminal by the PGW includes the following steps:

Step 201: The UE is successfully authenticated and attached to the eHRPD access network.

Step 202: The terminal initiates a PDN connection request from the primary connection to the HSGW, and notifies the HSGW by using a VSNCP configure request message.

Step 203: The HSGW sends an initial credit control request (CCR-I, Credit Control Request-initial) request to the PCRF, where the location information of the terminal carries the BSID (Base Station Identity Code).

Step 204: The PCRF returns an initial credit control response message (CCA-I, Credit Control Answer-initial) to the HSGW, and pushes the subscription terminal location change event to the HSGW;

Step 205: The HSGW sends a PBU message to the designated PGW, requesting to establish a Proxy Mobile IP (PMIP) tunnel of the terminal.

Step 206: The PGW completes the binding process of the terminal data session, and sends a PBA (Proxy Binding Acknowledgement) message to the HSGW.

Step 207: The HSGW sends a VSNCP configure response (VSNCP configure Ack) message to the terminal.

Step 208: The HSGW sends the VSNCP configuration request message again to complete the state machine negotiation of the point-to-point protocol (PPP).

Step 209: The terminal sends a VSNCP configuration response message correspondingly.

Step 210: The PGW sends a CCR-I request to the PCRF, and subscribes to the terminal location change event push;

Step 211: The PCRF successfully responds to the CCA-I to the PGW, and the response carries the location information BSID of the terminal. At this time, the terminal initial location information notification is completed.

Step 212: The terminal location is changed, and the PCF sends an A11 registration request message A11-RRQ request to the HSGW, where the location information of the terminal is carried, including the BSID and the Subnet of the terminal.

Step 213: The HSGW returns an A11 registration request to the PCF to respond to the A11-RRP response, and completes the A11 signaling interaction.

Step 214: The HSGW sends a CCR-U update request to the PCRF, where the terminal carries a new location information BSID, and notifies the PCRF terminal that the location changes.

Step 215: The PCRF returns a CCA-U response to the HSGW, and completes the diagnostic signaling interaction.

Step 216: The PCRF sends a Re-Auth-Request (RAR) request to the PGW, where the location information BSID of the terminal is carried, and the location of the PGW terminal is notified to be changed.

Step 217: The PGW returns a Re-Auth-Answer response (RAA) to the PCRF. At this point, the event push of the entire user location change to the PGW is completed.

It can be seen from the above process that even if the PCRF is deployed in the network and the HSGW supports the PCC function, it needs to perform 10 to 10 signaling interactions through steps 203-204, 210-211, and 212-217.

When the terminal does not need to perform tracking and positioning, the sending, by the HSGW, the PBU message carrying the location information includes: the HSGW periodically sending the extended location information of the terminal carrying the terminal according to a preset time period. PBU message to PGW;

Correspondingly, the location information of the terminal written by the HSGW in the extended PBU message includes: writing, in the extended PBU message, location information of the terminal in a preset time period; for example, writing in the PBU message All location information of the terminal within the PBU message transmission period. When the location of the terminal does not change during the preset time period, the HSGW does not send a PBU message to the PGW;

Or, when the terminal does not need to perform tracking and positioning, the HSGW sends the extended PBU message carrying the location information of the terminal to the PGW, including: when the network is refreshed or re-negotiated, the HSGW sends the extended carrying A PBU message with location information of the terminal to the PGW.
