Problems solved by technology
However, the cell ID provided by the UE cannot be considered authentic
The charging research group of 3GPP standards believes that if untrusted cell IDs are used in location-based charging and charging, it will cause very serious problems
However, the mechanism is not very efficient
If this mechanism is adopted, it will bring a large amount of message load to the data exchange domain (PS, Packet Switch)
In addition, the P-GW or GGSN cannot directly transmit the obtained trusted cell ID to the Home Subscriber Server (Home Subscriber Server, HSS) or any other application server in the IMS network
[0010] So far, in the existing standards and practical applications, there is no charging based on trusted location information using the SIP protocol in IMS and LTE networks

Embodiment Construction
[0025] figure 1 A schematic diagram of a network topology structure according to a specific embodiment of the present invention is shown. figure 1 A structural diagram of charging systems in LTE and IMS networks is shown. Among them, the LTE network is the bearer network, which is responsible for the transmission of data and signaling. The LTE network includes various gateways, such as S-GW and P-GW, and also includes base stations in the access network (referred to as NB in 2G networks, and in In the 3G network, there are evolved NB (referred to as eNB for short), and a mobility management entity (Mobility Management Entity, MME). The IMS network includes a home subscriber server (Home Subscriber Server, HSS), a proxy call / session control function (Proxy-Call / Session Control Function, P-CSCF), a serving call / session control function (Serving-Call / Session Control Function, S-CSCF), Offline Charging System (OFFline Charging System, OFCS), Online Charging System (Online Char...

The invention provides a method and a device for obtaining and using position information. A mobile management entity obtains credible user position information from a base station by a mobile management entity, and the credible position information is provided to a home subscriber server. By enhancing an interface between the home subscriber server and a service call / session control function, an interface between an agent user server and the service call / session control function, an interface between application servers, and an interface between an online charging system and an off-line charging system, the home subscriber server can provide the credible user position information to network units. An interface between an online charging system and the service call / session control function, an interface between the offline charging system and the service call / session control function, an interface between the agent user server and the service call / session control function, and an interface between the application servers are also enhanced so as to support the transmission of the credible user position information in the above interfaces.
Description
technical field [0001] The invention relates to an Internet Protocol Multimedia Subsystem, in particular to a method and device for acquiring and using position information in the Internet Protocol Multimedia Subsystem. Background technique [0002] Location information is very important in mobile voice and data charging. The location information typically includes the cell ID of the cell where the user terminal is located or the sector ID of the sector where the user terminal is located. [0003] In a traditional voice call network, a mobile switching center (Mobile Switching Center, MSC) usually provides a cell ID or a sector ID for a charging system for location-based charging and charging. The Cell ID or Sector ID provided by the MSC is considered authentic. [0004] In an LTE network, a base station (eNodeB, eNB, equivalent to NB in GPRS and UMTS networks) communicates with a Signaling Gateway (S-GW) or a public data network gateway ( The Public Data Network Gatewa...
