Description
Technical field
The present invention relates to moving communicating field, particularly relates to a kind of solve using adaptive single time slot multiuser channel voice
(VAMOS) method and system interfered when between base station sub-system (BSS).
Background technology
The net of shop mobile communication (GSM, Global System for Mobile Communications) system
Network framework as shown in figure 1, including 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 base station sub-system (BSS Base Station again
Subsystem).Wherein, the interface between core net and BSC is referred to as A interfaces, and the interface between BSC and BTS is referred to as Abis interface,
Interface between BTS and mobile terminal (MS) is referred to as Um Interface；Core net, BSC and BTS are cooperated, and complete move is provided to MS
Dynamic voice service function.
Traditional GSM is time division multiple acess (TDMA, Time Division Multi Access) system, and power system capacity is limited to
Time slot (TS, Time Slot) resource, and a TS can only carry simultaneously a full rate (FR, Full Rate) voice user or
Two half rate (HR, HalfRate) voice users of person.With the evolution of technology, there are many raising spectrum utilization efficiencies
Technology, adaptive single time slot multiuser channel voice (VAMOS, Voice services over Adaptive Multi-user
Channels on One Slot) technology is one kind therein.VAMOS technologies allow to carry two FR simultaneously on a TS
Voice user or 4 HR voice users, so as to improve whole GSM network pair on the premise of not requiring to increase frequency spectrum resource
The support of voice user's capacity.
With the continuous development and evolution of VAMOS technologies, the continuous maturation of technology, requirement of the operator to VAMOS technologies
Also it is continuously increased, while also focuses more on performance impact of the VAMOS technologies to network.
And conventionally, as BSS can not know that other BSS uses VAMOS situation, therefore BSS can only basis
Itself considers MS is matched or contacted using VAMOS to match using VAMOS situation.This, which is resulted in, is using VAMOS functions
Afterwards, the problem of VAMOS pairing channels between BSS mutually have an impact.Such as：BTS1 under BSS1 carries out user 1 and user 2
VAMOS pairings, the frequency 1 that uses, and user 3 and user 4 have been carried out VAMOS pairings by the BTS2 under BSS2, are also used
Frequency 1.Now, if BTS1 and BTS2 from it is close if, this four users will produce mutual interference.
The content of the invention
In view of this, it is a primary object of the present invention to provide a kind of solution using the side interfered between BSS during VAMOS
Method and system, to solve to use VAMOS situation each other due to that between BSS can not know, between caused BSS the interference of user ask

Embodiment
The present invention is solved using the core concept of the scheme interfered between BSS during VAMOS：Pass through the logic between BSS
Interface, send or receive VAMOS relevant information.
Specifically, as shown in Fig. 2 the method for the present invention includes：
Step 201, logic interfacing is configured between BSS；
As shown in figure 3, the present invention is on the existing gsm network architecture, an interface is configured between BSS and BSS, is passed through
The interface, VAMOS relevant information can be mutually transmitted between BSS.
It is preferred that the interface between BSS and BSS is a logic interfacing, the logic interfacing be based on Internet Protocol (IP,
Internet Protocol) carry or be time-multiplexed (TDM, Time Division Multiplex) carrying.
Message format between BSS uses the message transfer part in signalling system No.7 (Signalling System No.7.)
(MTP, Message Transfer Part) and SCCP (SCCP, Signalling Connection
Control Part) regulation.VAMOS relevant information is transmitted between BSS by above-mentioned message.
Step 202, VAMOS relevant information is transmitted between BSS by logic interfacing.
VAMOS relevant information includes one or more VAMOS unpaired messages.Each VAMOS unpaired messages include：Send
Frequency point information used in one group of terminal of VAMOS pairings and the cell at place letter are carried out under the BSS of VAMOS relevant information
Breath.
After the relevant information for receiving VAMOS, this method also includes：
Receive and carry out VAMOS pairings under BSS of the BSS of VAMOS relevant information according to the relevant information for sending VAMOS
One or more groups of terminals used in frequency point information, determine untapped frequency；
One or more groups of terminals under the BSS for the relevant information for receiving VAMOS are carried out according to untapped frequency
VAMOS is matched.
Between BSS by logic interfacing transmit VAMOS relevant information flow as shown in figure 4, in this embodiment it is assumed that
A logic interfacing is configured between BSS1 and BSS2, specifically, transmitting VAMOS by logic interfacing between BSS1 and BSS2
Related news flow, including：
Step 401, BSS1 sends message by logic interfacing to BSS2, and BSS1 VAMOS correlation is carried in the message
Information.
Wherein, frequency point information used in one group of terminal of VAMOS pairings and this group of terminal place will be carried out under BSS1
Cell information be referred to as a VAMOS unpaired message；When there is multigroup terminal to carry out VAMOS pairings under BSS1, then BSS1
VAMOS relevant information just includes multiple VAMOS unpaired messages.
As a kind of implementation, VAMOS relevant information can also be sent together with other information.
Step 402, BSS2 receives the message of BSS1 transmissions by logic interfacing, knows and VAMOS pairings are carried out under BSS1
Frequency used in one or more groups of terminals, it is possible thereby to determine untapped frequency.When to one or more groups of ends under BSS2
When end carries out VAMOS pairings, preferentially using the untapped frequency of above-mentioned determination.
Step 403, after BSS2 receives the message that BSS1 sends by logic interfacing, i.e. BSS2 receive BSS1 VAMOS
Relevant information after, give BSS1 send confirmation message.
It should be noted that requirement of the above-mentioned steps 402 with step 403 without tandem, step 402 are not required for
BSS2 is immediately performed after receiving the message of BSS1 transmissions, can be performed in step 403 after have sent confirmation message to BSS1,
It can be performed simultaneously with step 403.
In order to realize above-mentioned solution method, solved present invention also offers a kind of using being interfered between BSS during VAMOS
System, including：Configuration module and transport module；Wherein：
Configuration module, for configuring logic interfacing between BSS；
Transport module, for transmitting VAMOS relevant information between BSS by logic interfacing.
It is preferred that configuration module, is additionally operable to be carried based on Internet Protocol (IP) or time division multiplexing (TDM) is carried on
Logic interfacing is configured between BSS.
VAMOS relevant information includes one or more VAMOS unpaired messages.
Each VAMOS unpaired messages include：Send one group of end that VAMOS pairings are carried out under the BSS of VAMOS relevant information
Frequency point information used in end and the cell information at place.
The system also includes sending BSS and receives BSS,
Accordingly, transport module, it is additionally operable to the relevant information for sending BSS VAMOS being transferred to reception BSS；
BSS is received, after the relevant information for being additionally operable to receive VAMOS, the one of VAMOS pairings is carried out under BSS according to sending
Frequency point information used in group or multigroup terminal, determines untapped frequency；And according to untapped frequency to itself one group
Or multigroup terminal carries out VAMOS pairings.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.
