AI Technical Summary

Problems solved by technology

[0007] 1) Since there are two TC codec conversions in the transmission of the voice frame, it will cause a large delay, reduce the voice quality, and increase the waste of TC resources and Ater interface transmission resources;
[0008] 2) It will increase the bandwidth consumption of the Abis interface transmission network, and will cause the bottleneck of Abis interface transmission resources;
[0009] 3) Due to the participation of MSC, it will increase the waste of existing CN side network resources

Embodiment 1

[0084] Embodiment one, such as Figure 4 as shown, Figure 4 It is a schematic diagram of communicating and exchanging in the same BTS under the IP mode, and the method of the first embodiment includes:

[0085] Step 401, the BSC judges that the calling and called MSa and MSb are under the same BTS, specifically as follows Figure 4 As shown, it can be under BST1.

[0086] Step 402, the BSC determines that the speech coding rates in the access information of the calling mobile station and the called mobile station are the same, or if the speech coding rates in the access information of the calling mobile station and the called mobile station are different , adjust the speech coding rates of the calling and called mobile stations to the same rate.

[0087] Step 403, the BSC sends an instruction for communication exchange to the BTS1, the instruction carries an IWF table, and the information of the IWF table, such as:

[0088] uplink speech frame

downlink speech...

Embodiment 2

[0092] Embodiment two, such as Figure 5as shown, Figure 5 It is a schematic diagram of communication exchange in different BTSs, the method of the second embodiment includes:

[0093] Step 501, the BSC judges that the calling mobile station MSa and the called mobile station MSb come from different BTSs, and these different BTSs can communicate with each other through the IP transmission network, specifically as Figure 5 As shown, MSa may come from BTS1, MSb may come from BTS3, and BTS1 and BTS3 may communicate through an IP transmission network.

[0094] Step 502, the BSC determines that the speech coding rates in the access information of the calling mobile station and the called mobile station are the same, or if the speech coding rates in the access information of the calling mobile station and the called mobile station are different , adjust the speech coding rates of the calling and called mobile stations to the same rate.

[0095] Step 503, the BSC sends an instruc...

Embodiment 3

[0101] Embodiment three, such as Figure 6 as shown, Figure 6 It is a schematic diagram of performing communication exchange at the IP convergence BTS, the method of the third embodiment includes:

[0102] Step 601, the BSC judges that the calling mobile station MSa and the called mobile station MSb come from different BTSs, and these different BTSs are in different IP transmission networks, but they can be aggregated through IP transmission and converged BTSs for transmission and intercommunication, specifically as follows Figure 6 As shown, it may be: MSa comes from BTS1, MSb comes from BTS3, and BTS1 and BTS3 can communicate with each other through IP transmission and aggregation BTS.

[0103] Step 602, the BSC determines that the speech coding rates in the access information of the calling mobile station and the called mobile station are the same, or if the speech coding rates in the access information of the calling mobile station and the called mobile station are diff...

Abstract

In the embodiment, the invention discloses a method for carrying out the communication switching on a base transceiver station (BTS) and a base subsystem, relating to a telecommunication technology. The invention solves the problem of the communication switching between a calling mobile platform and a called mobile platform positioned on the same BTS set. The method comprises that whether the calling mobile platform and the called mobile platform are from the same BTS set of the same base controller BSC is judged; if yes, the calling mobile platform and the called mobile platform carry out the communication switching in a transmission convergence BTS of the BTS set; and the base subsystem comprises the base controller and the base transceiver station. The embodiment of the invention ensures that the calling mobile platform and the called mobile platform from the same BTS set can realize the communication switching in the transmission convergence BTS of the BTS set without coding / decoding for a voice frame through a converter TC.

Description

technical field [0001] The present invention relates to telecommunication technology, in particular to a method and a base station subsystem (Base Station Subsystem, BSS) for performing communication exchange at a base transceiver station (Base Transceiver Station, BTS). Background technique [0002] Taking the Global System for Mobile communications (GSM) as an example, in the GSM system, the base station subsystem usually includes: a base transceiver station, a base station controller (BaseStation Controller, BSC) and / or a transcoder (Transcoder, TC). The BTS communicates with the mobile station (Mobile Station, MS) through the Um wireless interface, and the TC is externally connected to the Mobile Switching Center (Mobile Switching Center, MSC) through the A interface. Inside the BSS, the BSC is connected to the BTS through the Abis interface, and to the TC through the Ater interface. connected. [0003] According to the GSM protocol, the BSS does not provide the switch...
