Embodiment 1

[0048] see figure 2 , which is a base station structure diagram of an LTE base station in the present invention, the base station includes a master BBU201, a slave BBU202, a slave BBU203, an IR switch 204 and an RRU205:

[0049] The main BBU 201 includes a main control unit 206 and n baseband processing units 207, where n is a natural number greater than or equal to 1.

[0050] The main control unit 206 of the main BBU is connected to the IR switch 204 and used to send configuration commands to the IR switch 204 .

[0051] What needs to be explained here is that the main BBU mentioned here does not specifically refer to a certain BBU, but can be any one of the BBUs connected to the IR switch. It is only necessary to load the corresponding control program to the main control unit of the BBU and communicate with the IR switch. The above functions can be realized by connecting, that is to say, when the main BBU fails during operation, other BBUs connected to the IR switch can b...

Embodiment 2

[0065] On the basis of Example 1, please refer to image 3 , which is another base station structural diagram of an LTE base station of the present invention:

[0066] The master control unit 208 of the slave BBU is connected to the master control unit 206 of the master BBU, and is also used to monitor the working status of the slave BBU 202 and send a maintenance request to the master control unit 206 of the master BBU according to the working status, The maintenance request includes address information of the baseband processing unit to be replaced and information about antenna data processed by the baseband processing unit.

[0067] The master control unit 210 of the slave BBU is connected to the master control unit 206 of the master BBU, and is used to monitor the working status of the slave BBU 203 and send a maintenance request to the master control unit 206 of the master BBU according to the working status. The maintenance request includes address information of the ba...

Embodiment 3

[0076] see Figure 5 , which is another base station structure diagram of an LTE base station in the present invention, including a clock unit 501, a master BBU201, a slave BBU202 and a slave BBU203:

[0077] The clock unit 501 is connected to the main control unit of each BBU outside the BBU, and is used to synchronize the clock frequency of each BBU.

[0078] The existing BBUs all have a clock unit, which is installed inside the BBU where it is located, and is used to provide the clock frequency for the BBU where it is located. This embodiment provides a clock unit 501, which is a separate device and is not subordinate to any BBU. It can provide synchronous clock frequency for all connected BBUs, and can provide services for the LTE base station described in Embodiment 1 or Embodiment 2. Multiple BBUs connected to the IR switch can be provided by the same clock unit The clock frequency of the base station not only greatly improves the stability of the entire base station, b...

Abstract

An embodiment of the invention discloses a long term evolution (LTE) base station and a base band resource exchanging method. The LTE base station is characterized by comprising a radio remote unit (RRU), at least two indoor base band processing units (BBUs) and an IR switch positioned outside the BBUs. The RRU is used for transmitting the received antenna data to the IR switch; the at least two BBUs include a main BBU and at least one auxiliary BBU subjected to the main BBU; a master control unit of the main BBU is connected with the IR switch and used for transmitting configuration commands to the IR switch; and the IR switch is positioned outside the BBUs and used for establishing paths enabling the received antenna data to flow to the BBUs according to the configuration commands of the main BBU and distributing the antenna data. By means of the method for exchanging the data outside the BBUs, exchange of the data among a plurality of BBUs can be achieved, and expansibility and flexibility of the LTE base station are greatly improved.

Description

technical field [0001] The present invention relates to the field of LTE base stations, in particular to an LTE base station and a method for exchanging baseband resources. Background technique [0002] In the wireless communication base station system, the technology of the baseband resource pool is often used. That is, the data of multiple sector antennas is distributed to multiple baseband processing units in the form of space division exchange, so that the many-to-many correspondence between baseband processing units and antennas can be achieved. When a certain baseband processing unit fails , the switching unit can route the antenna data to the normal baseband processing unit, ensuring that the functions of the entire base station will not be paralyzed. [0003] At present, the general LTE (Long Term Evolution) base station structure is more in the mode of BBU (Indoor Baseband Processing Unit) + RRU (Radio Remote Unit), such as figure 1 As shown, BBU1 is composed of m...
