For above-mentioned purpose, the feature and advantage that make the embodiment of the invention can be more obviously understandable, the embodiment of the invention is done further detailed explanation below in conjunction with accompanying drawing and embodiment.

Heterogeneous network in the present embodiment refers to the common cordless communication network of wireless communication system composition of different systems, it is understandable that, can comprise the wireless communication system of a plurality of different systems in the present invention in the heterogeneous network; Can be two or more, for example, (Wideband Code Division Multiple Access; Be called for short: WCDMA) system, (Code Division Multiple Access is called for short: CDMA) system; Global system for mobile communications (Global System For Mobile Communications; Be called for short: GSM), worldwide interoperability for microwave inserts (Worldwide Interoperability for Microwave Access, abbreviation: WIMAX); (Long Term Evolution is called for short: LTE) system or the like Long Term Evolution.For better understanding the present invention; The embodiment of the invention will be formed heterogeneous network with the wireless communication system of concrete LTE and two different systems of WCDMA and describe, but be equally applicable in the heterogeneous network that the wireless communication system of other different systems more than two forms.

In embodiments of the present invention, suppose, and the second communication system LTE system different with the first communication system standard forms heterogeneous network by the first communication system WCDMA system; To certain subscriber equipment business of (User Equipment is called for short UE), at first obtain this professional qos parameter from the shared core net of heterogeneous communication system; Send qos requirement message to two communication systems respectively then; In this qos requirement message, carrying is the information of two communication systems initial Q oS parameter of distributing respectively, and in this message, carries and require each communication system to feed back cell channel quality indicator (Channel Quality Indicator is called for short CQI) and the average down load in sub-district separately; Or CQI and ascending load; Distribute the qos parameter of two systems respectively according to received feedback information, or, data traffic; Or, up scheduling authorization.

Fig. 1 is a QoS of survice maintaining method schematic flow sheet in the embodiment of the invention heterogeneous network; As shown in Figure 1; QoS of survice maintaining method method in the heterogeneous network of the present invention is safeguarded the QoS that UE is professional in the network that at least two different systems communication systems are formed, its course of work can be described below.

S101, the shared core net of heterogeneous network is sent professional qos parameter

In the present embodiment, suppose the shared core net of LTE system and WCDMA system, this core net can be the core net of WCDMA system, and the RNC of WCDMA system can be used as the shared RNC of the heterogeneous network of LTE system and WCDMA system composition.Suppose the core net of the shared WCDMA of heterogeneous network that the first communication system WCDMA and the LTE of second communication system form; When initiating one when professional, core net with initiate this professional UE and consult this QoS of survice parameter of back decision, this qos parameter can comprise and amounts to Maximum Bit Rate (Aggregate Maximum Bit Rate; Abbreviation AMBR), guarantee bit rate (Guaranteed Bit Rate; Be called for short GBR), wherein, the concrete numerical value of AMBR and GBR can be relevant with type of service.The shared core net of heterogeneous network sends to this qos parameter the QoS attending device of heterogeneous network; Wherein, said QoS attending device can be the shared RNC of heterogeneous network, perhaps is arranged in the shared RNC of heterogeneous network; Perhaps be arranged in other communication equipments, the present invention does not limit.

S102 sends qos requirement message respectively to said at least two different systems communication systems.

Said qos requirement message is carried the information of the initial Q oS parameter of distributing for said two different systems communication systems and is required said at least two different systems communication systems to feed back the channel quality indicator (CQI) of sub-district, said UE place and the information of average down load.

For example, the QoS attending device of heterogeneous network can distribute initial Q oS parameter to different system, and requires the average down load of CQI and sub-district of sub-district, different communication system periodic feedback said UE place.

Give system and this initial Q of the LTE system assignment oS parameter of WCDMA respectively.It is understandable that, in order to satisfy this business realization, these two the initial Q oS of system parameters with need consult this professional qos parameter of back decision more than or equal to core net among the S101 and UE.

For example, the qos parameter of the initial Q oS parameter of these two communication systems business that equals respectively to determine among the S101; Perhaps, the qos parameter of the initial Q oS parameter of these two communication systems business that equals respectively to determine among the S101 is half the.

In this step, the QoS attending device of heterogeneous network can require the communication system of said at least two different systems to feed back the average down load of its sub-district CQI and sub-district respectively through qos requirement message simultaneously.For example; Is different in the WCDMA system with the residing sub-district of UE in the LTE system; Suppose the system at WCDMA, UE is in first sub-district, in the LTE system; UE is in second sub-district, and then WCDMA system and LTE system feed back the CQI and average down load of first sub-district and second sub-district respectively to the shared RNC of heterogeneous system.Particularly, this value of feedback can be to be reported to the residing base station in first sub-district and second sub-district respectively by UE, is reported to each self-corresponding RRC by the base station again, is fed back to the QoS attending device of heterogeneous network again by two RRC separately of system.For example, UE is periodic to base station reporting measurement data, and the QoS attending device that this value of feedback is fed back to heterogeneous network also can be periodic, and this cycle can be by the decision of heterogeneous system.

It is understandable that; Can send different qos requirement message to different systems respectively; For example; The QoS attending device of heterogeneous network send the first qos requirement message can for the WCDMA system, and the first qos requirement message is carried to be the assignment information of first communication system, the first initial Q oS parameter of distributing and to require the first communication system WCDMA periodically to send to the QoS of heterogeneous network attending device to use this professional UE in the WCDMA system, to belong to the information of the average down load of CQI and sub-district of sub-district.And; The QoS attending device of heterogeneous network can send the second qos requirement message to the LTE system, and the second qos requirement message is carried the assignment information of the second initial Q oS parameter of distributing for the LTE of second communication system and required the LTE of second communication system to send to the QoS of heterogeneous network attending device and uses this professional UE in this LTE system, to belong to the information of the average down load of CQI and sub-district of sub-district.

For example, divide timing in that two systems are carried out initial Q oS, can qos parameter that should business all be assigned to two systems, each system assignment qos parameter is respectively like this, AMBRn=AMBR/2, GBRn=GBR/2.It is understandable that, when the communication system of N different systems constitutes AMBRn=AMBR/N, GBRn=GBR/N, the different communication system of n representative wherein, N represents the total number of the system of different systems in this heterogeneous network, N=2 in the present embodiment, n=[1,2].

In another embodiment of the present invention, in that being carried out initial Q oS, at least two systems divide timing, and can all distribute qos parameter to each communication system is AMBRn=AMBR, GBRn=GBR, the wherein different communication system of n representative.It is understandable that after said two systems have been distributed initial Q oS respectively core net can send to data that should business the communication system of each different systems through the shared RNC of heterogeneous network at least.

S103, the said separately UE of communication system feedback of each different systems is at the average down load of the sub-district of each system CQI and sub-district;

The communication system of each different systems in the heterogeneous network can be according to the average down load of CQI and sub-district of sub-district, each self feed back of qos requirement message that receives said UE place; The average down load of CQI and sub-district of sub-district, the said UE of periodic feedback place separately for example; For example the RRC of WCDMA feeds back the average down load of CQI and sub-district of sub-district, said UE place, and the RRC of LTE feeds back the average down load of CQI and sub-district of sub-district, said UE place.If the system of a plurality of different systems is arranged, then the average down load of CQI and sub-district of sub-district, said UE place all feeds back in the system of a plurality of different systems.

S104 adjusts the qos parameter of said at least two different systems communication systems;

The QoS attending device of heterogeneous network is adjusted said at least two different systems communication system qos parameters according to the CQI of the sub-district that said at least two different systems communication systems are fed back respectively respectively with average down load.

For example; When heterogeneous system comprised the communication system of two different systems, the QoS attending device of heterogeneous network was adjusted the qos parameter of first communication system and second communication system according to the average down load information of CQI and sub-district of first communication system and second communication system feedback.

For example, the CQI of sub-district and local resource utilance are directly proportional, and when resource utilization was high more, the data that can transmit on the unit carrier resource were just many more.And the average down load in sub-district is high more, and then the load that can continue to increase of this sub-district is just few more.When the qos parameter of adjusting according to the average down load of CQI and sub-district to each system assignment, need make the qos parameter of adjusted each system be directly proportional with the CQI of the sub-district of using this professional UE in each communication system, to belong to, be inversely proportional to average down load.For realizing should business, the qos parameter that distributes in adjusted each communication system with need be more than or equal to this QoS of survice parameter that determines among the S101.

For example; When comprising the communication system of two different systems in the heterogeneous system; Through the average down load adjustment of CQI and sub-district qos parameter the time; Can be according to the calculated value adjustment qos parameter of employing formula a*CQI+ (the 1-a)/average down load in sub-district of each communication system, wherein, a=(0-1).It is understandable that; When comprising the communication system that surpasses two different systems in the heterogeneous system; The highest communication system of value of can be preferentially calculating gained at this formula is distributed qos parameter, further, and also can be in the difference between higher calculated value and the lower calculated value greater than preset thresholding; And when continuing to reach Preset Time, preferentially distribute qos parameter in the higher communication system of this calculated value.Further, when give calculated value higher the qos parameter that distributes of communication system and S101 in the qos parameter of the business that determines when also having difference, the difference of these two qos parameters distributed to another communication system.

When communication system is three and when above, according to the calculated value adjustment qos parameter of employing formula a*CQI+ (the 1-a)/average down load in sub-district of each communication system, wherein, a=(0-1) preferentially distributes qos parameter in the highest communication system of calculated value.Further, be higher than time high calculated value also can be preferentially for the highest and the highest said calculated value of calculated value and reach preset thresholding, and the communication system that continues to reach Preset Time is distributed qos parameter.Further; When there is difference in the qos parameter of the business that in giving calculated value qos parameter that higher communication system is distributed and S101, determines; Give other several communication systems with the difference mean allocation of these two qos parameters; Perhaps, will remain qos parameter according to the height of this formula calculated value of each system and distribute to other several communication systems from high to low.

S105 sends to each communication system respectively with adjusted qos parameter;

For example, the QoS attending device of heterogeneous network sends to adjusted qos parameter respectively the RRC of WCDMA system and LTE system.

In the present embodiment; At the beginning of business is initiated; The heterogeneous network core net is sent professional qos parameter, and the sub-district CQI according to different systems communication system under this heterogeneous network adjusts different systems communication system qos parameter with the average down load in sub-district again, make full use of a plurality of systems advantage; Efficient with more excellent satisfies QoS of survice, improves the wireless system resources utilance.

The present invention also provides QoS of survice attending device in a kind of heterogeneous network, is used for the professional QoS of network maintenance customer equipment UE that forms at least two different systems communication systems.

Fig. 2 is a QoS of survice attending device structural representation in a kind of heterogeneous network of the embodiment of the invention, and the QoS of survice attending device can be accomplished the part or all of step of QoS of survice maintaining method in the above-mentioned heterogeneous network in the said heterogeneous network.For ease of explanation, the QoS of survice attending device can comprise acquisition module 201, the first sending modules 202 in the said heterogeneous network, adjusting module 203, the second sending modules 204.

Acquisition module 201 is used for obtaining from least two shared core net of different systems communication system the qos parameter of said business.

Suppose the shared core net of LTE system and WCDMA system, this core net can be the core net of WCDMA system, and the RNC of WCDMA system can be used as the shared RNC of the heterogeneous network of LTE system and WCDMA system composition.Suppose the core net of the shared WCDMA of heterogeneous network that the first communication system WCDMA and the LTE of second communication system form; When initiating one when professional, core net with initiate this professional UE and consult this professional qos parameter of back decision, this qos parameter can comprise and amounts to Maximum Bit Rate (Aggregate Maximum Bit Rate; Abbreviation AMBR), guarantee bit rate (Guaranteed Bit Rate; Be called for short GBR), wherein, the concrete numerical value of AMBR and GBR can be relevant with type of service.Acquisition module 201 obtains that the shared core net of heterogeneous network sends above-mentioned qos parameter that should business.

First sending module 202; Be used for sending qos requirement message respectively at least two different systems communication systems, qos requirement message is carried the initial Q oS parameter information that distributes for each communication system and is required the channel quality indicator (CQI) of each sub-district, communication system feedback UE place and the information of average down load;

First sending module 202 can send qos requirement message respectively to different system, sends the first qos requirement message like the RRC that gives the WCDMA system, sends the second qos requirement message for the RRC of LTE system.

In the present embodiment; Because LTE system and WCDMA system form heterogeneous network; First sending module 202 carries the information into the first initial Q oS parameter of WCDMA system assignment in the first qos requirement message, and requires the first communication system WCDMA periodically to send this professional UE of use belongs to the average down load of CQI and sub-district of sub-district in the WCDMA system information to the QoS of heterogeneous network attending device.In the second qos requirement message, carrying the assignment information of the second initial Q oS parameter of distributing for the LTE of second communication system and requiring the LTE of second communication system to send to the QoS of heterogeneous network attending device uses this professional UE in this LTE system, to belong to the information of the average down load of CQI and sub-district of sub-district.It is understandable that, in order to satisfy this business realization, the first initial Q oS parameter and the second initial Q oS parameter and the qos parameter business that need be obtained more than or equal to acquisition module 201.For example, the first initial Q oS parameter and the second initial Q oS parameter equal the qos parameter of the business that acquisition module 201 obtained respectively; Perhaps, the first initial Q oS parameter and the second initial Q oS parameter equal qos parameter half the of the business that acquisition module 201 obtained respectively.

Adjusting module 203, the CQI of the sub-district that is used for feeding back respectively according to each communication system and average down load are adjusted the qos parameter of each communication system respectively;

Adjusting module 203 is adjusted said different systems communication system qos parameter according to the CQI of the sub-district that the different systems communication system is fed back respectively respectively with average down load.

For example, adjusting module 203 is adjusted the qos parameter of first communication system and second communication system according to the average down load information of CQI and sub-district of first communication system and second communication system feedback.

For example, the CQI of sub-district and local resource utilance are directly proportional, and when resource utilization was high more, the data that can transmit on the unit carrier resource were just many more.And the average down load in sub-district is high more, and then the load that can continue to increase of this sub-district is just few more.When the qos parameter of adjusting according to the average down load of CQI and sub-district to each system assignment, need make the qos parameter of adjusted each system be directly proportional with the CQI of the sub-district of using this professional UE in each communication system, to belong to, be inversely proportional to average down load.For realizing should business, the qos parameter that distributes in adjusted each communication system and the qos parameter business that need be obtained more than or equal to acquisition module 201.

When communication system is three and when above, according to the calculated value adjustment qos parameter of employing formula a*CQI+ (the 1-a)/average down load in sub-district of each communication system, wherein, a=(0-1) preferentially distributes qos parameter in the highest communication system of calculated value.Further, be higher than time high calculated value also can be preferentially for the highest and the highest said calculated value of calculated value and reach preset thresholding, and the communication system that continues to reach Preset Time is distributed qos parameter.Further; When give calculated value higher the qos parameter that distributes of communication system and S101 in the qos parameter of the business that determines when also having difference; Give other several communication systems with the difference mean allocation of these two qos parameters; Perhaps, will remain qos parameter according to the height of this formula calculated value of each system and distribute to other several communication systems from high to low.

Second sending module 204 is used for sending the qos requirement reallocation message to each communication system respectively, and the qos requirement reallocation message is carried adjusted qos parameter respectively.

Second sending module 204 sends the qos parameter of adjusting module 203 adjusted each systems respectively through the qos requirement reallocation message to different communication systems.

In another embodiment of the present invention, this adjusting module 203 can comprise:

Receiving element is used for receiving respectively the average down load information of CQI and sub-district of at least two different systems communication systems;

Adjustment unit is used for the qos parameter according at least two different systems communication systems of said information distribution of receiving element reception.

Understandable, in the present embodiment, the communication system of forming heterogeneous network can be arbitrary similar communication system known or that occur in the future, as long as the standard between these communication systems is different.In addition, in the present embodiment, the communication system of forming heterogeneous network can be two, and perhaps more than two, its implementation is similar.

In the present embodiment; In the communication system of two kinds of standards that comprise; First communication system is the WCDMA communication system, and when the second communication system was the LTE communication system, the QoS of survice attending device can be RNC in the heterogeneous network of the embodiment of the invention; This RNC can directly utilize original RNC in the WCDMA system, also can be the RNC that resets to this heterogeneous system integral body.Perhaps, in another embodiment of the present invention, the QoS of survice attending device can be an independently module that is arranged among the RNC in the said heterogeneous network.

In the present embodiment; At the beginning of business was initiated, acquisition module 201 obtained professional total qos parameter that the heterogeneous network core net is sent, and first sending module 202 sends qos requirement message to different communication systems; Adjusting module 203 is after receiving the message of feedback; According to the average down load adjustment of sub-district CQI and the sub-district different system qos parameter of the different system in the feedback message, second sending module 204 sends to each system with adjusted parameter, and the embodiment of the invention can make full use of the advantage of a plurality of systems when guaranteeing QoS of survice; Efficient with optimum satisfies QoS of survice, improves the wireless system resources utilance.

Another embodiment of the present invention provides QoS of survice maintaining method in a kind of heterogeneous network; Fig. 3 is a QoS of survice maintaining method schematic flow sheet in a kind of heterogeneous network of another embodiment of the present invention; As shown in Figure 3, QoS of survice maintaining method in a kind of heterogeneous network of the present invention comprises:

S301, the shared core net of heterogeneous network is sent professional total qos parameter and is distributed;

S302 sends qos requirement message respectively to said at least two different systems communication systems;

Give system and this initial Q of the LTE system assignment oS parameter of WCDMA respectively.It is understandable that, in order to satisfy this business realization, these two the initial Q oS of system parameters with need consult this professional qos parameter of back decision more than or equal to core net among the S301 and UE.

For example, the qos parameter of the initial Q oS parameter of these two communication systems business that equals respectively to determine among the S301 is half the.

For example, in another embodiment of the present invention, divide timing in that at least two systems are carried out initial Q oS, can all distribute qos parameter to each communication system is AMBRn=AMBR, GBRn=GBR, the wherein different communication system of n representative.It is understandable that after said two systems have been distributed initial Q oS respectively core net can send to data that should business the communication system of each different systems through the shared RNC of heterogeneous network at least.

S303, the communication system of said at least two different systems is sent the message of carrying initial flow control information (initial flow control info) and is given the QoS attending device.

Each communication system in said at least two different systems systems is the qos parameter and the service contracting QoS of original allocation relatively; Get the QoS that it has smaller value; Qos parameter according to this smaller value sends the message of carrying the initial flow control information to the shared RNC of heterogeneous system respectively again; Wherein, the flow that requires in the said initial flow control information is corresponding with the QoS of said smaller value.

S304 sends data for respectively each communication system according to the initial flow control information;

For example; Can know from this initial flow control information which kind of speed this base station can send downlink data with; The shared RNC of heterogeneous network sends the speed that downlink data can reach according to the base station of this professional data traffic and each system; The data traffic separated into two parts that this is professional carries out data to the communication system of said at least two different systems and sends.Further, can send the data of flow greatly to the bigger communication system of the speed that can reach.

S305, the average down load of CQI and sub-district of sub-district, each self feed back of the communication system of each different systems said UE place;

S306 distributes the data traffic of at least two different systems communication systems;

For example, when heterogeneous system comprises the communication system of two different systems, can be according to average down load information distribution first communication system of CQI and sub-district of said at least two different systems communication systems and the data traffic of second communication system.

For example, the CQI of sub-district and local resource utilance are directly proportional, and when resource utilization was high more, the data that can transmit on the unit carrier resource were just many more.And the average down load in sub-district is high more, and then the load that can continue to increase of this sub-district is just few more.When distributing to the data traffic of each system, need the data traffic of feasible each system that distributes to be directly proportional with the CQI of the sub-district of using this professional UE in each communication system, to belong to, to be inversely proportional to average down load according to the average down load of CQI and sub-district.

For example; When comprising the communication system of two different systems in the heterogeneous system; Through the average down load distribute data of CQI and sub-district flow the time; Can be according to the calculated value distribute data flow of employing formula a*CQI+ (the 1-a)/average down load in sub-district of each communication system, wherein, a=(0-1).It is understandable that; When comprising the communication system of two different systems in the heterogeneous system; Can be preferentially calculate the higher communication system distribute data flow of value of gained at this formula, further, also can be in the difference between higher calculated value and the lower calculated value greater than preset thresholding; And it is when continuing to reach Preset Time, preferential at the higher communication system distribute data flow of this calculated value.Further, when also having difference for the calculated value data traffic that higher communication system is distributed and this professional data traffic, the difference of data traffic is distributed to another communication system.

When communication system is three and when above, according to the calculated value distribute data flow of employing formula a*CQI+ (the 1-a)/average down load in sub-district of each communication system, wherein, and a=(0-1), preferential at the highest communication system distribute data flow of calculated value.Further, be higher than time high calculated value also can be preferentially for the highest and the highest said calculated value of calculated value and reach preset thresholding, and continue to reach the communication system distribute data flow of Preset Time.Further; When also having difference for the calculated value data traffic that higher communication system is distributed and this professional data traffic; Give other several communication systems with the difference mean allocation of data traffic; Perhaps, according to the height of this formula calculated value of each system remaining data traffic is distributed to other several communication systems from high to low.

Further embodiment of this invention provides QoS of survice maintaining method in a kind of heterogeneous network; Fig. 5 is a QoS of survice maintaining method schematic flow sheet in the embodiment of the invention heterogeneous network; As shown in Figure 5, QoS of survice maintaining method in a kind of heterogeneous network of the embodiment of the invention comprises:

S501, the shared core net of heterogeneous network are sent professional total qos parameter;

S502, send qos requirement message respectively to said at least two different systems communication systems;

Said qos requirement message is carried the information of the initial Q oS parameter of distributing for said two different systems communication systems and is required said at least two different systems communication systems to feed back the channel quality indicator (CQI) of sub-district, said UE place and the information of ascending load.

For example, the QoS attending device of heterogeneous network can distribute initial Q oS parameter to different system, and requires the CQI and the ascending load of cell of sub-district, different communication system periodic feedback said UE place.

Give system and this initial Q of the LTE system assignment oS parameter of WCDMA respectively.It is understandable that, in order to satisfy this business realization, these two the initial Q oS of system parameters with need be more than or equal to this professional qos parameter.

For example, the qos parameter of the initial Q oS parameter of these two communication systems business that equals respectively to determine among the S101 is half the.

In this step, the QoS attending device of heterogeneous network can require the communication system of said at least two different systems to feed back its sub-district CQI and ascending load of cell respectively through qos requirement message simultaneously.For example; Is different in the WCDMA system with the residing sub-district of UE in the LTE system; Suppose the system at WCDMA, UE is in first sub-district, in the LTE system; UE is in second sub-district, and then WCDMA system and LTE system feed back the CQI and the ascending load of first sub-district and second sub-district respectively to the shared RNC of heterogeneous system.Particularly, this value of feedback can be to be reported to the residing base station in first sub-district and second sub-district respectively by UE, is reported to each self-corresponding RRC by the base station again, is fed back to the QoS attending device of heterogeneous network again by two RRC separately of system.For example, UE is periodic to base station reporting measurement data, and the QoS attending device that this value of feedback is fed back to heterogeneous network also can be periodic, and this cycle can be by the decision of heterogeneous system.

It is understandable that; Can send different qos requirement message to different systems respectively; For example; The QoS attending device of heterogeneous network sends the first qos requirement message can for the WCDMA system; The first qos requirement message is carried to be the assignment information of first communication system, the first initial Q oS parameter of distributing and to require the first communication system WCDMA periodically to send to the QoS of heterogeneous network attending device to use this professional UE in the WCDMA system, to belong to the CQI of sub-district and the information of ascending load of cell; Or CQI and recruitment (the Rise Over Thermal of thermal noise of sub-district, place in the WCDMA system; Be called for short ROT); And the QoS attending device of heterogeneous network can send the second qos requirement message to the LTE system, and the second qos requirement message is carried the assignment information of the second initial Q oS parameter of distributing for the LTE of second communication system and required the LTE of second communication system to send to the QoS of heterogeneous network attending device and uses this professional UE in this LTE system, to belong to the CQI of sub-district and the information of ascending load of cell.

For example, the CQI of sub-district and local resource utilance are directly proportional, and when resource utilization was high more, the data that can transmit on the unit carrier resource were just many more.And ascending load is high more, and then the load that can continue to increase of this sub-district is just few more.When the uplink authorization scheduling of distributing to each system assignment according to CQI and ascending load, need to make that the data traffic of each system of distributing is directly proportional with the CQI of the sub-district of using this professional UE in each communication system, to belong to, and ascending load be inversely proportional to.

For example; When comprising the communication system of two different systems in the heterogeneous system, when distributing the uplink authorization scheduling, can distribute uplink authorization to dispatch according to the calculated value of employing formula a*CQI+ (the 1-a)/ascending load of each communication system through CQI and ascending load; Wherein, a=(0-1).It is understandable that; When comprising the communication system of two different systems in the heterogeneous system; The higher communication system of value of can be preferentially calculating gained at this formula is distributed the uplink authorization scheduling, further, and also can be in the difference between higher calculated value and the lower calculated value greater than preset thresholding; And when continuing to reach Preset Time, preferentially distribute the uplink authorization scheduling in the higher communication system of this calculated value.Further, when also having difference for the calculated value data traffic that higher communication system is distributed and this professional data traffic, the difference of data traffic is distributed to another communication system.

When communication system is three and when above, distribute the uplink authorization scheduling according to the calculated value of employing formula a*CQI+ (the 1-a)/ascending load of each communication system, wherein, a=(0-1) preferentially distributes the uplink authorization scheduling in the highest communication system of calculated value.Further, be higher than time high calculated value also can be preferentially for the highest and the highest said calculated value of calculated value and reach preset thresholding, and the communication system that continues to reach Preset Time is distributed the uplink authorization scheduling.Further; When also having difference for the calculated value data traffic that higher communication system is distributed and this professional data traffic; Give other several communication systems with the difference mean allocation of data traffic; Perhaps, according to the height of this formula calculated value of each system remaining data traffic is distributed to other several communication systems from high to low.

S505, the uplink authorization in allocation step scheduling sent to the communication system of at least two different systems respectively;

For example, the QoS attending device will be gone up the RRC that the uplink authorization scheduling that distributes in the step sends to WCDMA system and LTE system respectively.Concrete can send with the mode of prior art through the form of message.

In the present embodiment; At the beginning of business is initiated; The heterogeneous network core net is sent professional uplink authorization scheduling, and the sub-district CQI according to different system under this heterogeneous network distributes the uplink authorization of different system to dispatch with ascending load again, make full use of a plurality of systems advantage; Efficient with optimum satisfies QoS of survice, improves the wireless system resources utilance.

Another embodiment of the present invention also provides QoS of survice attending device in a kind of heterogeneous network; The QoS of survice attending device can be accomplished the part or all of step of QoS of survice maintaining method in the above-mentioned heterogeneous network in the said heterogeneous network; The technical scheme of present embodiment can be referring to Fig. 2, and is as shown in Figure 2
