Description
Technical field
The present invention relates to the communications field more particularly to a kind of switching handling methods and base being related to local call local exchange
It stands subsystem.
Background technology
In existing global system for mobile communications (Global System for Mobile Communications, abbreviation
For GSM) in, including core net (Core Network, referred to as CN) and access net (Access Network) two parts, wherein
Core net includes mobile switching centre (Mobile Switching Center Server, referred to as MSC Server or MSC)
With Media Gateway (Media GateWay, referred to as MGW), access net includes base station sub-system (Base Station
Subsystem, referred to as BSS) and mobile terminal (Mobile Station, referred to as MS).Lead between core net and access net
It crosses A mouthfuls to be attached, be communicated by Um Interface between base station sub-system and mobile terminal.As shown in Figure 1.
Currently in order to saving transfer resource, local call local exchange function (Local Call Local are introduced
Switch, abbreviation LCLS), i.e., directly the user-plane voice of a side of local call is not sent to separately by the MGW of core net
One side.Gsm system after call is established, if when without using local call local exchange function, user that BSS can will be received from MS
Face data is transmitted to MGW, and the user face data received from MGW is transmitted to MS.And in use local exchange function, BSS can be incited somebody to action
The user face data that MS is received from side is transmitted to other side MS, avoids user face data passing to MGW processes, to reduce
From the expense of transfer resource.As shown in Figure 2.
After using local exchange function, when the one party MS of call needs to be switched to another BSS, due to cutting
The both sides to converse after changing will provide service by different BSS, therefore can cause to may require that release local exchange in handoff procedure
Function.And during switching, for the MS not switched over, BSS needs simultaneously that the uplink user face data received is same
When be sent to core net and link-local.
A kind of triggering BSS has been contained in 48.008 V10.4.0 of 3GPP TS while sending uplink user face number at present
According to the granting to core net and link-local, after BSS receives switching command, the uplink that the MS never switched over is received is used
Family face data is sent to core net and link-local simultaneously.But due to the switch instances that BSS can not know switching MS, cause
BSS can not adjust the sending method to the uplink user face data of terminal in time.
Invention content
After using local exchange function, when side, MS needs to be switched to another BSS, the other side is not carried out
The BSS needs of the MS of switching will receive that uplink user face data is double simultaneously to issue core net and link-local, but the BSS can not
Sending method of the adjustment to the uplink user face data of terminal in time.
The technical problem to be solved in the present invention is to provide a kind of switching handling method being related to local call local exchange and
Base station sub-system, the BSS for solving the MS not switched in the both ends conversed by link-local can not in time be adjusted to terminal
Uplink user face data sending method the problem of.
