Charging method and device under hybrid networking

This application claims priority to Chinese Patent Application No. 201310452641.6, entitled "Billing Method and Apparatus under Hybrid Networking", filed on September 25, 2013, the entire contents of which are hereby incorporated by reference. Combined in this application. Technical field

The present invention relates to the field of data processing technologies, and in particular, to a charging method and apparatus in a hybrid networking. Background technique

LTE (Long Term Evolution) is a 3G (3rd Generation, 3rd Generation) next-generation evolution technology that not only has 100Mbit/s data download capability, but also supports multi-band, high bandwidth, low latency, The characteristics of being suitable for networking with multiple networks are becoming more and more important in communication technology.

For example, TD-LTE (TD-SCDMA Long Term Evolution, long-term evolution of TD-SCDMA) TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) and FDD LTE (Frequency Division Duplex Long Term Evolution) The long-term evolution of frequency division multiplexing is two network standards of LTE. Among them, FDD LTE has good coverage and is suitable for coverage. TD-LTE has relatively large spectrum bandwidth and is suitable for capacity. With the increasing scarcity of spectrum resources and the rapid development of high-traffic data services, FDD LTE / TD-LTE hybrid networking has become a trend.

For example, some operators' LTE experimental networks are adopting the strategy of "hybrid networking and synchronous deployment". The same NIC implements two wireless access modes, TD-LTE and FDD LTE, to perform LTE network test verification. In the future, the networking strategy for this hybrid networking is: Large-scale, wide-coverage 4G (4th, Generation, fourth-generation) networks use the FDD system, while densely populated areas in the city will use the TDD system to absorb excess traffic. , in order to achieve the purpose of making full use of frequency resources. Come on LTE itself It is said that the similarity between TD-LTE and FDD LTE is 90%, which is consistent in the operation standards and specifications of the core network and the core network. Therefore, one EPC (Evolved Packet Core) is shared for the two types of LTE access networks. The evolved packet core network) provides technical guarantees for the core network, as shown in Figure 1.

In the case of hybrid networking, TD-LTE and FDD LTE share an EPC core network, and users move between the two radio access networks. In the actual application process, the operator needs to know the service traffic generated by the users of the EPC core network in the two systems. However, because there is no hybrid network in the existing network, the existing 3GPP (3rd) The Generation Partnership Project, the third-generation mobile communication standardization organization), the protocol and the process in the protocol specification are not differentiated from the FDD network standard or the TDD network standard. The 3GPP related specifications also do not describe the related processes and protocols in the case of hybrid networking. The EPC core network only It is possible to perform unified charging for E-UTRAN (Evolved Universal Terrestrial Radio Access Network), and it is impossible to distinguish between TD-LTE and FDD LTE network standards. When the two network standards are respectively composed of the corresponding EPS (Evolved Packet System), there is no impact on the operation of the network, but in the case of FDD LTE and TD-LTE hybrid networking, EPS Department

(Business & Operation Support System, Operation Support System) cannot separately formulate charging policies and count business traffic for the services generated under the two network systems. Therefore, the flexibility of charging is poor. Summary of the invention
