Embodiment 1

[0073] Figure 5 It is the first method of the load reporting method between the UMTS system and the LTE system in the embodiment of the present application. The main idea of ​​the first method of this application is: the UMTS base station and the LTE base station are in one device, which is called a multi-mode base station. Through the internal interface, the UMTS base station can obtain the load information of the LTE cell, and the LTE base station can also obtain the load information of the UMTS cell. load information. Afterwards, the UMTS base station reports the load information of the LTE cell to the base station controller of the UMTS system, and the base station controller can refer to the load information of the LTE cell during handover and load sharing. Such as Figure 5 As shown, the method includes the following steps:

[0074] Step 501: the radio network controller RNC of the UMTS system sends a resource status request message to the base station of the UMTS sy...

Embodiment 2

[0088] Image 6 It is another embodiment of the first method of the load reporting method between the UMTS system and the LTE system in the embodiment of the present application. Such as Image 6 As shown, the method includes the following steps:

[0089] Step 601: The base station of the UMTS system sends an information notification message to the RNC. The purpose of the message is to inform the RNC that the base station is a multi-mode base station and can provide load information of an LTE cell.

[0090] The message contains one or more of the following information

[0091] 1) Instructions for multi-mode base stations;

[0092] 2) The information of the LTE cell, including the information of the LTE cell on the multi-mode base station, the cell information includes at least the cell unique identifier CGI, and may also include information such as the frequency of the cell;

[0093] 3) The information of the LTE cell, including the information of the LTE cell on the multi...

Embodiment 3

[0109] Figure 7 It is another embodiment of the first method of the load reporting method between the UMTS system and the LTE system in the embodiment of the present application. Such as Figure 7 As shown, the UMTS and LTE base stations are in one device, which is a multi-mode base station, and the method includes the following steps:

[0110] Step 701: The base station of the UMTS system sends a status report to the RNC of the UMTS system.

[0111] The message contains the unique identifier of the LTE cell and the load of the cell. The base station of the UMTS system obtains the load information of the LTE cell through the internal interface, and can also obtain the load information of the surrounding LTE cells through the LTE base station on the multi-mode base station, and the UMTS base station sends the load information to the RNC through step 701.

[0112] Step 702: The RNC of the UMTS system sends a status report confirmation message to the base station of the UMTS ...

Abstract

The application discloses a method for a load report between a universal mobile telecommunications system UMTS and a long term evolution LTE system. A radio network controller RNC of the UMTS sends a resource state request message to a base station of the UMTS. The base station of the UMTS sends a resource state report message to the RNC. The resource state report message carries unique identification of an LTE community and load information of the community. According to the technical scheme of the application, the method for the load report between the UMTS and the LTE system is optimized. The base station of the UMTS reports the load information of the LTE community to the controller of the base station, or the base station in which the LTE community is located reports community information of the UMTS to other eNBs so that forwarding through a core network is not needed, burden of the core network is reduced, delay of the load report is reduced and network efficiency is enhanced.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to a load reporting method between a UMTS system and an LTE system. Background technique [0002] Modern mobile communication technologies tend to provide users with high-speed multimedia services, among which UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) and LTE (Long Term Evolution, Long Term Evolution) are more typical. [0003] figure 1 It is a system architecture diagram of the LTE system. next to figure 1 The various components of the LTE system shown are introduced: [0004] UE (User Equipment, user equipment) 101 is a terminal device used to receive data. [0005] E-UTRAN (Evolved UMTS Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) 102 is a radio access network, including: a macro base station (eNodeB (eNB for short) / NodeB ), the macro base station is also calle...
