Description
Technical field
The present invention relates to moving communicating field, the method and system of phase mutual interference between base station sub-system (BSS) when referring to especially a kind of solution use single time slot multiuser channel voice of self adaptation (VAMOS).
Background technology
Tradition global system for mobile telecommunications (GSM, Global System for Mobile Communications) network architecture of system as shown in Figure 1, comprise core net, base station controller (BSC, Base Station Controller) and base station (BTS, Base Transceiver Station) three layers, BSC and BTS can be collectively referred to as again base station sub-system (BSS Base Station Subsystem).Wherein, the interface between core net and the BSC is called the A interface, and the interface between BSC and BTS is called Abis interface, and the interface between BTS and portable terminal (MS) is called Um Interface; Core net, BSC and BTS collaborative work provide complete mobile voice service function to MS.
Tradition GSM is time division multiple access (TDMA, Time Division Multi Access) system, power system capacity is subject to time slot (TS, Time Slot) resource, and a TS can only carry a full rate (FR simultaneously, Full Rate) voice user or two half rates (HR, HalfRate) voice user.Evolution along with technology, the technology that many raising spectrum utilization efficiencies occurred, single time slot multiuser channel voice (VAMOS, the Voice services over Adaptive Multi-user channels on One Slot) technology of self adaptation is wherein a kind of.The VAMOS technology allows to carry simultaneously two FR voice users or 4 HR voice users on a TS, thereby has improved whole GSM network to the support of voice user's capacity under the prerequisite that does not require the increase frequency spectrum resource.
Along with the continuous maturation of the development of VAMOS technology and evolution, technology, operator also constantly increases the requirement of VAMOS technology, also more pays close attention to the VAMOS technology to the performance impact of network simultaneously.
And in the prior art, because BSS can not be known the situation of other BSS use VAMOS, so BSS can only consider to use VAMOS pairing or contact to match to MS according to the situation of self using VAMOS.This just causes after using the VAMOS function, the problem that the VAMOS pairing channel between BSS exerts an influence mutually.For example: the BTS1 under the BSS1 has carried out the VAMOS pairing with user 1 and user 2, the frequency 1 of use, and the BTS2 under the BSS2 has carried out the VAMOS pairing with user 3 and user 4, the frequency 1 that also uses.At this moment, if BTS1 and BTS2 from very close to, these four users will produce mutual interference.
