Multi-Mode Base Station realizes it generally being that base station unit with multiple types is integrated into an equipment, normally adopts simple integrated forming on basis, single mode base station.On the hardware resource, but partial sharing (such as rack, fan, power supply, transmission etc.) between the various communication standards of Multi-Mode Base Station, and remainder keeps independent; And software function and protocol stack structure are continued to use the framework of public network macro base station substantially, and its topological diagram as shown in Figure 1.

Shown in topological diagram, existing Multi-Mode Base Station is communicated by letter by the radio open realization with terminal, is connected by cable transmission network (normal operation ATM or IP transmission technology) with BSC/RNC/EPC/AC etc.For the GSM/UMTS standard, Multi-Mode Base Station is between terminal and the wireless controller (BSC/RNC); For the LTE pattern, Multi-Mode Base Station is between terminal and evolution core net; For the WIFI pattern, Multi-Mode Base Station is between terminal and AC.The below further sets forth the structure of Multi-Mode Base Station take the GSM/UMTS standard as example.

As shown in Figure 2, existing GSM/UMTS network configuration is that middle wireless network is comprised of the two layers of mesh meta structure: the ground floor network element is base station (BS), and second layer network element is radio network controller (RNC or BSC).Directly do not connect between the base station, many stylobates station is connected to a RNC/BSC, and many RNC/BSC are connected to concentrated core network element equipment (MSC/SGSN); A RNC/BSC can control many stylobates station, is responsible for many stylobates station administration, and the cooperation between the base station is all finished by RNC/BSC, all must pass through RNC/BSC alternately between all base stations.

As can be known; for indoor scene; if adopting above Multi-Mode Base Station disposes; to run into because base station number is too many; the BSC, the RNC that need are more; not only cause constructional difficulties owing to the network configuration bulky complex, and the high network construction cost that causes of the equipment cost of BSC, RNC is higher, complex structure can increase simultaneously the propagation delay time of packet and increase the probability of network failure.

For overcoming the above problems, use for reference the flat network topology structuring concept among the LTE, the utility model proposes the novel Multi-Mode Base Station that network and other corresponding networks to the GSM/UMTS standard carry out flattening.

Summary of the invention
