In recent years, GSM (Global System for Mobile Communications, global system for mobile communications）Number of users and voice service occur in that explosive growth.How more effective service more efficiently is provided for more users using existing base station and frequency resource, into one of most concerned problem of operator.

In 3GPP (3rd Generation Partnership Project, third generation partner program）GERAN (GSM EDGE Radio Access Network, evolved speed enhancing gsm wireless access network) in #33 plenary sessions, a kind of imagination for increasing voice capacity is suggested first, i.e. OSC (Orthogonal Sub Channel, orthogonal sub-channels）, access two MS (Mobile Station, movement station simultaneously in a physical slot by time）, it is made a distinction by orthogonal training sequence.This way can make available channel quantity double in the case where not increasing base station number and frequency resource.Later, this concept development turned into VAMOS (Voice services over Adaptive Multiuser Orthogonal Subchannels, the speech business based on adaptive multiuser orthogonal sub-channels）.In VAMOS systems, BSC (Base Station Controller, base station controller）Carry out data transmission using by two user's concurrent multiplexings to same slotted mode.Two users are multiplexed on same time slot and are referred to as " pairing ", according to the convention described to planisphere, the two can be referred to as to I roads user and Q roads user.When being multiplexed more than one user on some time slot in VAMOS modes, the time slot is claimed to be in VAMOS patterns.In existing VAMOS technologies, it is considered that I roads, which can access conventional mobile phone, (realizes DARP Phase I mobile phone, or mobile phone earlier）, Q roads, which must be accessed, realizes the mobile phone of VAMOS technologies.

VAMOS candidate technologies have OSC, a-QPSK (Quadrature Phase Shift Keying, QPSK）And co-TCH (Co- Traffic Channel, public voice channel）Deng these three candidate technologies are essentially identical in principle. The introducing of VAMOS technologies so that BSC, which can be used, carries out data transmission two user's concurrent multiplexings to same slotted mode.Due to now it is each with per family can by another user strong jamming, cause be in VAMOS pairing states under user channel quality degradation.Under this scene, the FER of data transfer rises, call voice Quality Down, it is impossible to provide the session service of high qos requirement, and damages user experience.

And the QoS information further comprises the information for whether allowing the channel of the distribution to be changed after the completion of channel distribution, such as：Full rate VAMOS channels whether are allowed to be converted to the information of half rate VAMOS channels, half rate VAMOS channels whether are allowed to be converted to the information of full rate VAMOS channels, full rate TCH channels whether are allowed to be converted to the information of half rate VAMOS channels, or the information for whether allowing half rate TCH channels to be converted to full rate VAMOS channels；And the QoS information further comprises the information that whether allows the channel of the distribution to be changed after the completion of channel distribution, such as：VAMOS channels whether are allowed to be converted to the information of TCH channels；Or whether allow TCH channels to be converted to the information of VAMOS channels. In certain embodiments of the invention, " channel rate and type " cell coding information is not limited to table 3, can also there is other forms.Table 3 is only a scheme of embodiments of the invention.

3) " Speech version allowed identifies (Permitted speech version indication) " cell is directed to speech business, and " Permitted speech version indication " cell is used for the Speech version for indicating that current business allows.The Speech version that session is finally used is selected by BSC based on priority.Its selection principle is as follows：

If having clear and definite channel speed requirement in " channel rate and type " cell, the requirement of " Permitted speech version indication " cell can not be sky, and the Speech version in cell according to priority should just sort.The Speech version that first byte is indicated is limit priority Speech version.

If only giving the priority principle of channel speed in " channel rate and type " cell, then the requirement of " Permitted speech version indication " cell can not be sky, and the Speech version in cell is first according to the priority ranking of channel speed, sorted for same channel speed by Speech version priority height.The Speech version that first byte is indicated is limit priority Speech version.

Under the ungratified scene of above-mentioned condition, the Speech version in cell according to priority should just sort.The Speech version that first byte is indicated is limit priority Speech version

Specific Speech version coding is as shown in table 4.

Table 4, Speech version coding information

5202nd, BSC is after the allocation request message of MSC transmissions is received, and the correspondence quality of service information determines the traffic channel types needed for the current business.

5203rd, the BSC correspondences traffic channel types distribute Traffic Channel for the current business.

Work as quality of service information, when representing current business such as the QoS information in embodiment for higher level business, the required traffic channel types of the current business to should determine that can be TCH channels, QoS information can also be corresponded to and determine that the TCH channels are half-rate channel or full speed channel, the quality of the conversation of senior various-service is so ensure that.When QoS information represents current business for common or relatively low level various-service, traffic channel types needed for should determine that current business can be VOMAS, or further determine that the VOMAS channels are half-rate channel or full speed channel, to make full use of system resource.

In embodiment, MSC can also indicate the channel information that BSC is preferentially distributed by the QoS information, it is possible to further indicate whether the conversion for allowing the channel to carry out full rate/half rate.Illustrate below and the embodiment of the present invention is illustrated, in following citing, MSC represents the QoS information of current business by " the channel rate and type " cell in allocation request message.

For example, for the not high speech business of a qos requirement, MSC includes 1,001 1011 this coding shown in table 3 in " channel rate and type " cell coding in the allocation request message, implication is：" complete/half rate TCH/VAMOS channels, half rate VAMOS channel priors.After the completion of the channel distribution of this request, complete half is not allowed to change ".Allow the priority of the Speech version used to define and see " Permitted speech version indication " cell.Thus BSC will be preferably the traffic assignments half rate VAMOS channels, and in follow-up voice call process, all no longer carry out channel conversion.

And for example, for the Client-initiated speech business of a high qos requirement, MSC includes 0,100 1011 this coding shown in table 3 in " channel rate and type " cell coding in the allocation request message, and implication is：" complete/half rate TCH/VAMOS channels, full rate TCH channel priors.After the completion of the channel distribution of this request, it is allowed to complete partly to change, complete half changes preferentially ".Allow the priority of the Speech version used to define and see " Permitted speech version indication " cell.Thus BSC will be preferably the traffic assignments full rate TCH channels, but can be preferably that user considers to be transformed on half rate TCH channels if user load is aggravated in follow-up voice call process.If user is in Half Speed When on rate TCH channels, serving cell load is still overweight can not to realize normal talking, then can consider whether to be switched on VAMOS channels for user.

For another example, for the speech business initiated the higher contracted user of qos requirement, MSC includes 0,001 1010 this coding shown in table 3 in " channel rate and type " cell coding in the allocation request message, and implication is：" complete/half rate TCH channels, full rate TCH channel priors.After the completion of the channel distribution of this request, complete half is not allowed to change ".Allow the priority of the Speech version used to define and see " Permitted speech version indication " cell.Thus BSC will be preferably the traffic assignments full rate TCH channels, and in follow-up voice call process, all no longer carry out channel conversion.So as to the business data transmission for the user for ensureing high qos requirement, Consumer's Experience is improved.

S204, in BSC it is that the feedback message that is assigned will be sent to MSC after current business distributes channel.This step is optional step.

In addition, if BSC, which is current business, converted channel, the feedback message of channel conversion can also be sent to MSC.

Embodiments of the invention are not limited to only be extended by " channel rate and type " in " Channel Type " cell, it can also realize the QoS information carrying by VAMOS channels in Assignment Request message by extending other different cells, for VAMOS a variety of channels of the traffic assignments including VAMOS, more data available transmission channels corresponding with customer demand are provided for client so as to realize under existing base station and frequency resource.

Embodiment two

The step of the present embodiment, can be identical with Fig. 2.When MSC sends allocation request message (Assignment Request) to BSC, the scheme of the present embodiment introduces a new cell in the request message, and the cell includes quality of service information of the current business based on VAMOS type channels.

Specifically, a kind of QoS extension frameworks based on VAMOS priority are proposed in the present embodiment.The framework is that ASSIGNMENT REQUEST message introduces a new cell, and " VAMOS priority schemes VAMOS preference^ MSC are by cell instruction BSC, the VAMOS channel types needed for the qos requirement of current business.BSC just blunt can adjudicate whether current business may be selected by VAMOS channel bearings in actually distribution wireless channel according to the cell. " VAMOS preference " specific coding information of cell is as shown in table 5.

The coding information of table 5, " VAMOS preference " cell

As shown in table 5, when MSC selects VAMOS the use priority only to use TCH channels, BSC will only be the traffic assignments TCH channels of terminal.The selection of complete/half rate TCH channels is selected by BSC according to existing " channel rate and type " cell in channel allocation.When MSC selects VAMOS the use priority only to use VAMOS channels, BSC will only be terminal distribution VAMOS channels.Channel speed selects full rate or half rate to be made decisions also according to existing " channel rate and type " cell.

If MSC selections VAMOS the use priority is TCH preferential, BSC will be preferably terminal distribution TCH channels.Channel speed selects full rate or half rate to be made decisions also according to " channel rate and type " cell.BSC can not be only met under the performance requirement of current area, such as not enough scene of channel capacity requirement for terminal distribution TCH channels, just decided whether as terminal distribution VAMOS channels.In communication process, when the channel quality and cell load of terminal, which change, requires that BSC progress channels are reconfigured, BSC also should be preferably terminal configuration TCH channels.

Similarly, the preferential scenes of VAMOS are selected for MSC, if current cell load is heavier, BSC will be preferably terminal distribution VAMOS channels.The selection of full rate or half rate TCH channels is selected by BSC according to existing " channel rate and type " cell in channel allocation.In communication process, when the channel quality and cell load of terminal, which change, requires that BSC progress channels are reconfigured, BSC should also pay the utmost attention to configure VAMOS channels for terminal.

For under the scene of TCH channels and VAMOS channels without prioritization, BSC can be according to RRM (the Radio Resource Manage, RRM of itself）The channel of algorithm arbitrary disposition user Type.

Embodiments of the invention are not limited merely to by adding " VAMOS preference " cell in Assignment Request message, the QoS information that other cells carry VAMOS channels can also be added, more data available transmission channels corresponding with customer demand are provided under existing base station and frequency resource for client so as to realize.

Embodiment three

The step of the present embodiment, can be identical with Fig. 2.When MSC sends allocation request message Assignment Request to BSC, " priority riority " cell of the scheme of the present embodiment in the request message includes QoS information of the current business based on VAMOS type channels.

Utilize original vacant bit in " priority " cell（Bit) 8, the bit is newly defined as " VAMOS permits VAMOS permitted " cell.The coding structure of " priority " cell is as shown in table 6.

The coding structure of table 6, " priority " cell The priority that the program is contracted only for client determines whether the qos requirement of current sessions business can use VAMOS channel bearings.For high-priority users, MSC indicates BSC by " VAMOS permitted " cell, and current business can not be configured on VAMOS channels.BSC will only be active user's distribution TCH channels.For domestic consumer, " VAMOS permitted " cell is then positioned to allow for current business configuration on VAMOS channels by MSC.The height for the User Priority that BSC is then indicated according to " priority " cell in cell load and Assignment Request message, the user of low priority is preferentially configured on VAMOS channels.It is worth noting that, under this scene, no matter which kind of degree cell load rises to, it is set to not allow high-priority users of the current business configuration on VAMOS channels for " VAMOS permitted " cell, will remain in all the time on TCH channels.

By " VAMOS permitted " bit, it may be such that BSC area separates the high priority session that can only be distributed on TCH channels, so as to ensure that the QoS service quality for being supplied to high ranked user. Embodiments of the invention are not limited merely to carry the QoS information of VAMOS channels by the vacant bit of " priority " in Assignment Request message, and the vacant bit in other cells can also be used to carry the QoS information of VAMOS channels.

Embodiments of the invention can correspond to different QoS requirement business by traffic assignments to include full rate TCH, half rate TCH and full rate VAMOS, a variety of channels such as half rate VAMOS, and whether to allow conversion to be defined in follow-up communication process, thus embodiments of the invention are further segmented by the qos requirement to VAMOS systems in granularity, so that gsm system is introducing VAMOS channels with the basis of extending power system capacity, the QoS service quality of high-priority users is in turn ensure that simultaneously, so as to ensure that the usage experience of high-priority users.Embodiments of the invention are realized provides more data available transmission channels corresponding with customer demand under existing base station and frequency resource for client, improves the service efficiency of Radio Resource, improves Consumer's Experience.As shown in figure 3, embodiments of the invention additionally provide a kind of distributor of gsm service channel, including：
