Example Embodiment

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] like Figure 4 As shown, in the UMTS system, the CN30 and the UTRAN60 are connected through an Iu interface, where the Iu interface is the same as the Iu interface stipulated in the 3rd Generation Partnership Project (3GPP for short) protocol.

[0052] In UTRAN60, there are several RNS61, and each RNS61 is connected through Iur interface, wherein the Iur interface is the same as the Iur interface stipulated in the 3GPP protocol. Physically, the Iur interface can be realized through direct physical connection between RCHE65 in RNS61 or through transmission network connection.

[0053] Each RNS61 contains one RCHE65 and several RTS68, and each RTS68 is connected to RCHE65 through the Iut interface. It should be noted that the Iut interface is a newly defined interface in the present invention, which is different from the Iub interface stipulated in the 3GPP protocol.

[0054] RCHE65 is used to allocate and control the radio resources of TRS68 connected or related to it, that is, connection establishment and disconnection, handover, macro-diversity combination, radio resource management control, etc. Specifically, it includes performing system information broadcasting and system access control functions, mobility management functions such as handover and RTS68 migration, and radio resource management and control functions such as macro-diversity combining, power control, and radio bearer allocation. It should be noted that the above functions are the same as those of the original RNC25.

[0055] In addition, RCHE65 in the present invention is also responsible for the processing of baseband data. That is, the uplink completes functions such as demodulation and decoding processing, and the downlink completes functions such as channel coding, forward modulation, and power control.

[0056] This shows that RCHE65 of the present invention and figure 2 and image 3 The difference between the RNC25 in the prior art is that there is one more baseband data processing function. In fact, the functions to be realized by the BB module 51 in the original NodeB28 are transferred to the RCHE65 in the present invention.

[0057] Therefore if Figure 5 As shown, structurally, the RCHE65 of the present invention includes the original RNC25 and the BB module 51 in the NodeB28, and these two modules are connected to each other.

[0058] The RTS68 is used to perform intermediate frequency and radio frequency processing on the baseband signal sent to it by the RCHE65, and communicate with the UE through a wireless interface.

[0059] like Figure 5 As shown, the RTS68 includes an IF module 52 and an RF module 53 connected to each other, and the BB module 51 originally in the NodeB28 is transferred to the RCHE65. It should be noted that the IF module 52 and the RF module 53 in the RTS68 are completely the same in function and structure as the IF module 52 and the RF module 53 in the NodeB28. The RF module 53 communicates with the UE through the transmitting antenna. The IF module 52 is connected with the BB module 51 in the RCHE65 through the Iut interface.

[0060] In the present invention, since the BB module 51 is transferred to the RCHE65, the baseband processing resources of the BB module 51 can be shared in the entire RNS61 range, reducing the number of BB modules 51 with high cost, so the wireless access In terms of network, the total cost will be greatly reduced.

[0061] In addition, since the baseband processing is concentrated in RCHE65, the negotiation signaling between RCHE65 and RTS68 will be greatly reduced, that is, the message flow of internal nodes in the radio access network will be greatly reduced, thereby reducing signaling load and improving service establishment efficiency.

[0062] Compared with NodeB, the functions of RTS68 are simplified, so the volume will be easier to make smaller to meet the needs of operators.

[0063] Although the present invention has been illustrated and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein, and without departing from the spirit and scope of the invention as defined by the appended claims.
