sea lily piano wire jewelry wholesale What is the communication BSC

zodiac jewelry wholesale BSC refers to the base station controller.
It is a connection point between the base station receiving platform (BTS) and the mobile exchange center (MSC). It also provides interfaces for the exchange information between the base station receiving and receiving platform and the mobile exchange center. A base station controller usually controls several base stations.
BSC's main functions are to perform wireless channel management, implement the establishment and demolition of calls and communication links, and control the switching of the transferred area in the controlled area in this control area.
The expansion information: General BSC consists of the following modules:
1) AM/CM module: the center of the road exchange and information exchange.
2) BM module: Complete call processing, signaling processing, wireless resource management, wireless link management and circuit maintenance function.
3) TCSM module: Complete the reuse and replacement function.
BSC's function list is as follows:
1) Pagagine management, BSC is responsible for allocating paging messages from MSC. In this regard, it is actually a special transparent channel between MSC and MS.
2) Transfer network management, BSC configuration, allocation and monitoring 64KBPS circuits between RBS, it also directly controls the exchange function in RBS. This exchange function can effectively use 64K circuits.
3) The code type transformation function, the four full -speed GSM channels are used as a 64K channel, the sound is encoded in the BSC, a PCM time slot can transmit 4 phonetic connections. This function is implemented by Trau.
4) Speaking coding.
5) The operation and maintenance of BSS, BSC is responsible for the operation and maintenance of the entire BSS. Such as system data management, software installation, device occlusion and unconticials, alarm processing, testing data collection, and receiving letter test.
6) The surveillance and management of wireless base stations, RBS resources are controlled by BSC, and at the same time, through the internal software testing and ring road test on the speech channel, BSC can also monitor the performance of RBS.

It is a connection point between the base station receiving station and the mobile exchange center. It also provides interfaces between the exchange information between the base station receiving platform (BTS) and the mobile exchange center (MSC). A base station controller usually controls several base stations. The main function is to perform wireless channel management, implement the establishment and demolition of calls and communication links.
The expansion data base station controller is between MSC and BTS. The task is to manage the wireless network, that is, the operation and maintenance of the wireless community and its wireless channels, wireless devices, and the business process of mobile platforms, and provide base stations to MSC between interface. Try to concentrate the functions of wireless control to BSC as much as possible to simplify the base station equipment. Its functions are as follows:

1. The surveillance and management of wireless base stations, RBS resources are controlled by BSC. At the same time, through the internal software testing and circuit test on the speech channel, BSC can also monitor the performance of RBS. Ericsson's base station uses internal software testing and circuit test to monitor TRX on the speaking channel. If the failure is detected, the RBS will be configured to activate the backup TRX, so that the original channel group remains unchanged.
2. The management of wireless resources, BSC configure business and control channels for each community. In order to re -configure accurately, BSC collects various statistical data. For example, the number of losses, success and unsuccessful switching, business volume of each community, wireless environment, etc., special record functions can track all events of the call process. These functions can detect network faults and fault devices.
3. Treatment the connection with the mobile platform, be responsible for the establishment and release of the connection with the mobile desk, allocate a logical channel for each way, the call period, the BSC monitor the connection, the signal strength and the quality of the phonetic voice of the mobile platform and the sending letter, and the measurement result of the measurement. Back to BSC.
Reference data base station controller

It is a connection point between the base station receiving station and the mobile exchange center. It also provides interfaces between the exchange information between the base station receiving platform (BTS) and the mobile exchange center (MSC). A base station controller usually controls several base stations. The main function is to carry out wireless channel management, implement the establishment and demolition of calls and communication links, and control the transfers of the transferred area in this control area.
generally consisting of the following modules:
am/cm module: the center of the road exchange and information exchange.
BM module: complete call processing, signaling processing, wireless resource management, wireless link management and circuit maintenance function. TCSM module: Complete the reuse and code transformation function.
Predent information can refer to mobile communication related knowledge.
The base station controller (BSC): BSC controls a group of base stations, its task is to manage wireless networks, that is, managing wireless communities and its wireless channels, operations and maintenance of wireless devices, the business process of mobile platforms, and providing base stations to base stations to providing base station to Interface between MSC. Concentrate the functions of wireless control to BSC as much as possible to simplify the equipment of the base station, which is a feature of GSM. Its function list is as follows:
1. The surveillance and management of wireless base stations, RBS resources are controlled by BSC. At the same time, through the internal software testing and circuit test on the speech channel, BSC can also monitor the performance of RBS. Ericsson's base station uses internal software testing and circuit test to monitor TRX on the speaking channel. If the failure is detected, the RBS will be configured to activate the backup TRX, so that the original channel group remains unchanged.
2. The management of wireless resources, BSC configure business and control channels for each community. In order to re -configure accurately, BSC collects various statistical data. For example, the number of losses, success and unsuccessful switching, business volume of each community, wireless environment, etc., special record functions can track all events of the call process. These functions can detect network faults and fault devices. 3. Processing the connection with the mobile platform, responsible for the establishment and release of the connection with the mobile platform, allocate a logical channel to each way. During the call period, the BSC monitor the connection, the mobile platform and the receipt letter measurement signal intensity and the quality of the voice voice. The measurement results return BSC. BSC decides the launching power of the mobile platform and the sender, and its purpose is to ensure good connection quality and reduce the interference in the network to minimize.
4. Positioning and switching, switching is controlled by BSC, and the positioning function of the positioning function is continuously analyzed the quality of the phonetic sound. As a result, the decision to switch should be divided into BSC switching. Switch. A special switch is called the community switch. When the BSC finds that the quality of a connection is too low, and the measurement result is not found in the measurement result, the BSC will be switched to another logical channel in this community. Hope the quality of calls will improve. Switching can be used to balance the load in the community. If the amount of calls in a community is too high, and the number of adjacent communities is small, and the signal quality can be acceptable, some calls will be forcibly switched to other communities to other communities.

6. The management of the transmission network, the BSC configuration, allocating and monitoring the 64kbps circuit between RBS, it also directly controls the exchange function in RBS. This exchange function can effectively use 64K circuits.
7. The code -type transformation function is used to complete the four full -speed GSM channels into a 64K channel. The sound encoding is completed in the BSC. A PCM time slot can transmit 4 phonetic connections. This function is implemented by Trau.
