Fig. 5 is the structural representation of communication system provided in an embodiment of the present invention.Embodiment various embodiments of the present invention to current MSA technologies after being improved, it is proposed that a kind of new shunting multiplexing mechanism.Various embodiments of the present invention can be applied in the application scenarios including user equipment and two base stations.The two base stations can be macro base station；It can also be micro-base station；Can also be respectively macro base station and micro-base station.User equipment can for mobile phone or other can with base station carry out radio communication terminal device.
In LTE system, in the case of not using shunting mode, following communication process is included between base station and UE.
Base station sends uplink transmission resource approval message on Physical Downlink Control Channel (physical downlink control channel, PDCCH)；UE is according to the uplink transmission resource approval message received, it is determined that to be included in medium access control（Media Access Control, MAC) layer Packet Data Unit (Packet Data Unit, PDU) in each logical channel data total amount, and MAC layer control unit（Control Element, CE) allocation space.
UE, can be by the Service Data Unit of Different Logic channel according to default multiplexing rule when sending upstream data to base station（Service Data Unit, SDU) in data, and data in the CE of MAC layer are assembled in PDU corresponding with the base station.The data in PDU are assembled to, the base station corresponding to it can be sent to.
Specifically, can include one or more logic channels in UE, each logic channel is correspondingly arranged on a variable Bj, and the variable is used for the amount for representing the allocated resource of the corresponding logic channel first run.At the beginning of logic channel is established, Bj initial value is 0, i.e., in an initial condition, without available resources in logic channel；Hereafter, the amount of the available resources in logic channel is in each Transmission Time Interval（Transmission Time Interval, TTI) in, i.e., in every millisecond, it is incremented by with a fixed Walk length, the size of the Walk length is priority bit speed（Priority Bit Rate, PBR) .Wherein, each logic channel is respectively arranged with corresponding PBR.But, direct relation is had no between the height of the priority of logic channel and the PBR of logic channel size, the higher logic channel of priority, its PBR is not necessarily high；Priority is relatively low Logic channel, its PBR is not necessarily low.
The amount of the allocated resource of the amount of available resources, the i.e. first run, can correspondingly be reduced after business datum is assigned in each logic channel, the numerical value of reduction PDU data volume is assembled to for this this logic channel；Growth thereafter over time is continued reinforcement mouthful by the amount for the resource being allocated in the logic channel, but can't be increased unlimitedly.The amount of the allocated resource of each logic channel first run is respectively provided with respective maximum, i.e. its PBR and amount of storage duration（Bucket Size Duration, BSD) product.Wherein, PBR and BSD numerical value can be configured by base station to UE；Or voluntarily set by UE, and signals base after the setup.
Because logic channel is corresponding with type of service, when there is business to be sent in UE, according to the type of business to be sent, it is determined that the logic channel being transmitted to business to be sent.Data in business to be sent are loaded into the logic channel by the amount for the resource being allocated according to the first run in logic channel, UE.
If the amount of resource currently allocated is more than or equal to the data volume of business to be sent in the logic channel, business to be sent can be fully loaded on the logic channel；If the amount of resource currently allocated is less than the data volume of business to be sent in the logic channel, the partial data of the amount of current allocated resource can will be equal in business to be sent, is first loaded on the logic channel.
Orders of the UE according to the priority of each logic channel from high to low, the data in each logic channel are assembled in the corresponding PDU of target BS, and the amount for the resource for being correspondingly respectively allocated logic channel reduces the size of loaded data volume.Hereafter, for being more than the data that logic channel is currently allocated the amount of resource in business to be sent, UE does not consider further that logic channel is allocated the size of the amount of resource in the second wheel assembling, but the part that will not sent in business to be sent, it is fully loaded on corresponding logic channel.Data in the higher logic channel of priority, are first assembled in the corresponding PDU of target BS by orders of the UE according to the priority of each logic channel from high to low；Data in the logic channel that priority is higher are assembled in the corresponding PDU of the target BS after all assembling is finished, then by the data in the relatively low logic channel of priority.
After the shunting multiplexing mechanism proposed in employing various embodiments of the present invention, the communication process between base station and UE is as follows.
Fig. 1 is the flow chart of service shunting method provided in an embodiment of the present invention, as shown in figure 1, this method includes：
101st, user equipment is according to the type of service of business to be sent, it is determined that logic channel corresponding with the type of service, the first diverting coefficient corresponding with first base station and the second shunting corresponding with the second base station Coefficient.Wherein, the first run that the allocated resource of the logic channel first run includes being obtained according to first diverting coefficient distributes first resource, and the first run obtained according to second diverting coefficient distributes Secondary resource.
Specifically, UE includes one or more logic channels, each logic channel is used for the business datum for transmitting corresponding type of service.That is, types of service of the UE according to business, can determine and utilize which logical channel transmission business.Also include at least one pair of diverting coefficient corresponding with each type of service difference in UE, UE can determine and diverting coefficient is handled the business using which according to the type of service of business.
When thering is business datum to need to be sent to base station in UE, according to the type of service of business to be sent, it is determined that needing the logic channel and a pair of diverting coefficients utilized.A pair of diverting coefficients include the first diverting coefficient and the second diverting coefficient, and the two diverting coefficients are corresponding with two base stations respectively.Business to be sent is sent on two base stations by UE using a pair of diverting coefficients, to play a part of shunting multiplexing.
Diverting coefficient can be set by base station for UE, can voluntarily be set by UE and signals base.The base station can be first base station or the second base station or other base stations.
Because diverting coefficient is corresponding with type of service, therefore for control signaling or for the business datum of delay sensitive, a pair of diverting coefficients corresponding with this kind of business can be set to 0 and 1.Wherein, the corresponding diverting coefficient in the preferable base station of current channel transmission mass ratio is set to 1, the reliability of data is received that is, can be handled for this kind of business without shunting to increase base station.Thus, it is possible to effectively improve transmission quality.
In actual applications, for the data service insensitive to time delay, the first diverting coefficient and/or the second diverting coefficient corresponding with the second base station with first base station can be dynamically adjusted according to the quality and first base station and the load condition of the second base station of transmission.
For example, if the load of first base station is relatively heavy, the load of the second base station is relatively light, then can set smaller by the first diverting coefficient corresponding with first base station, such as 0.3;The second diverting coefficient corresponding with the second base station is set larger, such as 0.7.So as to so that 70% data of the data service are sent to the second base station, and 30% data are sent to first base station, can effectively carry out the load balancing between base station.
UE is after the logic channel for needing to utilize is determined, in addition it is also necessary to determine the amount of the allocated resource of the logic channel first run.The allocated resource of the logic channel first run includes two parts, is that the first run obtained according to the first diverting coefficient distributes first resource respectively, and the first run obtained according to the second diverting coefficient is distributed Secondary resource.That is, UE is according to the proportionate relationship between the first diverting coefficient and the second diverting coefficient, by the overall partition of available resources being allocated in the first run of logic channel for two parts.
" the allocated resource of the logic channel first run " described in various embodiments of the present invention refers to when current business to be sent is loaded to corresponding logic channel, the current resource being allocated in the logic channel, the maximum of resource that the size of the resource is likely less than or can be allocated equal to the logic channel.
Because UE needs to send business to be sent to two base stations, there is PDU corresponding with each base station respectively in UE, it is therefore desirable to business to be sent is respectively assembled to the two base stations and distinguished in corresponding PDU.Respectively in PDU corresponding with each base station free space number, set by corresponding base station.
Correspondingly, the resource that the logic channel first run is allocated is divided into after first run distribution first resource and first run distribution Secondary resource, this two parts resource is corresponding with two base stations respectively, that is, the business datum in this two parts resource will be mounted in PDU corresponding with two base stations respectively.
In this case, logic channel no longer needs to be associated with single base station, but can be diverted to the business datum transmitted in each logic channel on two base stations, effectively optimizes the effect of Network Load Balance.
Wherein, the computational methods and dynamic changing process of the amount of available resources current in logic channel, can be used and similar implementation in the prior art.
102nd, the delineation of activities to be sent, according to first diverting coefficient and second diverting coefficient, is the first packet and the second packet by user equipment.
Specifically, UE is after the first diverting coefficient and the second diverting coefficient is determined, it is two parts, respectively the first packet and the second packet by delineation of activities to be sent according to the proportionate relationship between the first diverting coefficient and the second diverting coefficient.
Wherein, the first diverting coefficient, first run distribution first resource and the first packet are all corresponding with first base station；Second diverting coefficient, first run distribution Secondary resource and the second packet are all corresponding with the second base station.
103rd, user equipment is more than or equal to the data volume of first packet in the amount for judging the first run distribution first resource, and the amount of first run distribution Secondary resource is when being more than or equal to the data volume of second packet, first resource is distributed using the first run, first packet is assembled in PDU corresponding with the first base station, and Secondary resource is distributed using the first run, second packet is assembled in the corresponding PDU in second base station.
Specifically, UE is after by delineation of activities to be sent for the first packet and the second packet, respectively Judge whether the amount of first run distribution first resource is more than or equal to the data volume of the first packet, and whether first run distribution Secondary resource is more than or equal to the data volume of the second packet.If the two conditions are satisfied by, then it represents that have enough resources to be used to send the business to be sent in logic channel.
