Description
Technical field
The present invention relates to the mobile communication technology field, particularly relate to the methods, devices and systems of code conversion and rate adapted.
Background technology
GSM (Global System for Mobile communication, global system for mobile communications) is a second generation digital cellular mobile communication systems, and BSS (Base Station Subsystem, base station sub-system) is the Radio Access Network of GSM.The GSM network architecture and the BSS position in GSM can be with reference to shown in Figure 1.
In the tradition, NSS (Network SubSystem, network subsystem) side adopts the physical transfer of 64k bit/s speed to transmit the user's voice data, and the interface between the BSS, is defined by the A interface.The BSS side adopts the more voice coding modes such as RPE-LTP (the Regular Pulse Excited Long TermPrediction of low rate, Regular-Pulse Excitation-long-term prediction, be full rate FR), CELP (Code Excited LinearPredictive Coding, Qualcomm Code Excited Linear Prediction (QCELP), i.e. enhanced full rate EFR) etc.; In BSS inside, the band width in physical speed of the required Abis interface of these voice coding modes (interface between base station and the BSC) is all less than 16kbit/s.User data on the Um Interface is arranged to use the 8bit/s or the 16kbit/s transmission bandwidth of Abis interface, is delivered to BSC inside.
TRAU (Transcoder/Adaptor Unit, code conversion and Rate Adapter Unit) is special relatively functional unit in the GSM system, and it finishes NSS side standard 64kbit/s speed and BSS inside than conversion between the low rate and submultiplex function.Point out that the BSS system needs the TRAU function in the regulation in People's Republic of China's communication industry standard " YD/T883-1999900/1800MHz TDMA digital cellular mobile communication systems second stage base station sub-system equipment and technology requires and the wireless index method of testing " the 4th chapter, and defined seven kinds of deployment forms.
The method that realizes code conversion and rate adapted in the background technology can be divided into two classes basically:
The first kind is that the TRAU that will realize code conversion and rate adaptation function is positioned over the BSS outside, is an independent physical entity.Directly join by simple transmission cable (as E1/T1/STM-1/IP etc.) between TRAU and the BSC, be connected by transmission network (as SDH, PDH etc.) between TRAU and the MSC.Its concrete structural representation can be with reference to shown in Figure 2.
TRAU function in the such scheme, use machine frame packing in physics realization is stand-alone network elements on logic realization or be the network element that is subjected to BSC control.At this moment, the flow process that user data transmits in BSC and TRAU can be with reference to shown in Figure 3.
The technical problem of background technology 1 is:
1, be connected by transmission cable between TRAU and the BSC, TRAU and BSC need to increase interface unit (interface board) respectively and come the adapted transmission cable; Be connected by transmission network between TRAU and the MSC, TRAU and MSC need to increase interface unit (interface board) respectively and come the adapted transmission network;
2, the TRAU function needs the machine frame of physics physically, needs operator to provide the machine room space to hold the TRAU function; These machine frames have increased the power consumption of system;
3, to carry out repeatedly exchange and switching to user data, not only reduce QoS (Quality of Service, service quality), also reduce the reliability of whole network simultaneously user data;
4, TRAU is placed on the BSS side, a plurality of user speech can not be carried out multiplexingly, can not utilize the submultiplex function (can with at least 4 user's voice data multiplexs on a 64Kpbs) of TCSM, the resource of having wasted transmission network.
The implementation method of the second class background technology is the outside that TRAU is arranged on BSS, occurs as an independent physical entity.Join by transmission network (as SDH, PDH etc.) between TRAU and the BSC, directly be connected by simple transmission cable (as E1/T1/STM-1/IP etc.) between TRAU and the MSC.Its structure can be with reference to shown in Figure 4.This technical scheme has overcome the 4th technical problem of first kind technical scheme, still, its TRAU function, machine frame cabinet packing that equally need be independent in physics realization is stand-alone network elements on logic realization or be the network element that is subjected to BSC control.At this moment, the schematic flow sheet that user data transmits in BSC and TRAU can be with reference to shown in Figure 5.
The technical problem of background technology 2 is:
Though background technology 2 has overcome the 4th technical problem of background technology 1, still exist with background technology 1 in identical preceding 3 technical problems.
Comprehensive above the analysis, as seen, there are the following problems at least in the background technology:
Because can not being embedded in the base station controller, code conversion in the background technology and rate adaptation function realize, thereby make under the situation that the transmission network available transmission resources is enriched day by day, the base station controller disposal ability constantly strengthens, the code conversion and the rate adaptation function entity that exist with physically independent community's form, in occupation of more space and resource, increased the power consumption of system; The more important thing is, increased user data exchange and switching number of times, thereby reduced the service quality that offers user data.
Summary of the invention
In view of this, the purpose of the one or more embodiment of the present invention is to provide the methods, devices and systems of a kind of code conversion and rate adapted, with realization code conversion and rate adaptation function are embedded in the base station controller, the system resource that code conversion and rate adaptation function are occupied in the minimizing background technology, reduce the number of times of user data exchange switching, improve the quality of user's service.
For addressing the above problem, the embodiment of the invention provides
The method of a kind of code conversion and rate adapted comprises:
Reception is set up the user data connection requests or is discharged the user data connection requests;
If detect embedded code conversion and rate adaptation function, then:
For the described user data connection requests of setting up, assigned code conversion and rate adapted resource; Or,
