The first embodiment of the present invention is a network system 1, and its schematic diagram is depicted in Fig. 1.Network system 1 comprises user's device 11, femtocell thereof (femtocell) 13 and a micro base station management device 15, wherein, user's device 11 wirelessly communicates with femtocell thereof 13, femtocell thereof 13 wirelessly or wired mode one of them communicate with micro base station management device 15.
Please refer to Fig. 2, it describes the schematic diagram of femtocell thereof 13 and micro base station management device 15.Femtocell thereof 13 comprises Transmit-Receive Unit 131 and a processing unit 133, and Transmit-Receive Unit 131 and processing unit 133 are electrically connected; Micro base station management device 15 comprises Transmit-Receive Unit 151 and a processing unit 153, and Transmit-Receive Unit 151 and processing unit 153 are electrically connected.Wherein, Transmit-Receive Unit 131 and Transmit-Receive Unit 151 wirelessly or wired mode one of them be electrically connected.
First, illustrate how femtocell thereof 13 of the present invention sets up an interference figure.In true environment for use, one or more contiguous femtocell thereof may be had in the communication range of femtocell thereof 13 simultaneously, because the communication range of contiguous femtocell thereof and femtocell thereof 13 overlaps, therefore, when femtocell thereof 13 carries out Signal transmissions separately with contiguous femtocell thereof, the interference in communication is just likely caused.In order to avoid interference problem, femtocell thereof 13 must set up the interference figure of record and contiguous femtocell thereof relative distance.
After femtocell thereof 13 is started shooting, first femtocell thereof 13 is registered to micro base station management device 15; Then, femtocell thereof 13 sends a broadcast singal by Transmit-Receive Unit 131, wherein, in order to record compared with the contiguous femtocell thereof within the scope of large regions, femtocell thereof 13 sends this broadcast singal with twice power level, and namely this broadcast singal can be passed to twice communication distance.After one or more contiguous femtocell thereof around femtocell thereof 13 receives this broadcast singal, return a response signal immediately to femtocell thereof 13, the processing unit 133 of femtocell thereof 13 just can learn the identity (identification of contiguous femtocell thereof according to this response signal; ID), and record the distance between contiguous femtocell thereof and femtocell thereof 13, finally, femtocell thereof 13 sets up an interference figure according to the result detected.
Refer to Fig. 3, it describes the schematic diagram of the interference figure that femtocell thereof is set up.5 contiguous femtocell thereofs are had in the adjacent domain that have recorded femtocell thereof 13 in interference Figure 130, its work D is respectively femtocell thereof A-E, and the distance that have recorded between femtocell thereof 13 and each contiguous femtocell thereof, distance such as between femtocell thereof A and femtocell thereof 13 is 3 meters (3m), by that analogy.Accordingly, ID and the distance of other femtocell thereof in femtocell thereof 13 adjacent domain just can be learnt according to interference Figure 130.
The person of should be specified, in the present embodiment, femtocell thereof 13 sends the broadcast singal of twice power level to detect the contiguous femtocell thereof in twice communication distance, in other embodiment, femtocell thereof also can send the broadcast singal of any power level to detect the contiguous femtocell thereof in femtocell thereof adjacent domain, does not therefore limit the scope of the invention with the size of detection range.
When user's device 11 is for use wireless network resource, user's device 11 sends request signal 110 a to femtocell thereof 13, comprises a request frequency range and a request service credit rating distinguished symbol (QoSclassidentifier in request signal 110; QCI), wherein, this request frequency range is in order to represent the wireless network frequency range required by user's device 11, and this request service credit rating distinguished symbol is then in order to indicate the service quality (QualityofService required by user's device 11; QoS) grade.
The Transmit-Receive Unit 131 of femtocell thereof 13 is after reception request signal 110, request signal 110 is sent to processing unit 133, and first processing unit 133 can judge the frequency range whether femtocell thereof 13 can provide request signal 110 to ask and service quality rating; If not, represent that femtocell thereof 13 cannot provide service required by request signal 110, then processing unit 133 throws aside request signal 110, and namely femtocell thereof 13 does not provide wireless network resource to user's device 11; If so, then processing unit 133 is determined further.
More be provided with a queue in femtocell thereof 13, this queue is sent to service request pending in femtocell thereof 13 in order to scheduling.In detail, in high capacity when, femtocell thereof 13 may receive the service request of multiple user's device simultaneously, and therefore each service request can be temporary in queue by processing unit 133, more sequentially processes each service request according to the priority of each service request.
On the other hand, request signal 110 has more first-class and treats time limit D
qCI (110), wait for time limit D
qCI (110)then can the stand-by period in order to what represent request signal 110, wait for time limit D
qCIbeing determined by the QCI of request signal, different QCI corresponds to different wait time limit D
qCI.Generally speaking, the higher service quality rating permissible wait time limit is shorter; Anti-, the lower service quality rating wait time limit that then tolerable is longer.
From the above, processing unit 133 is after judging its frequency range that request signal 110 can be provided to ask and service quality rating, processing unit 133 can first calculate a queue wait time, and this queue wait time represents that femtocell thereof 13 processes the time of the required cost of whole pending service request in this queue.Then, processing unit 133 judges the wait time limit D of request signal 110
qCI (110)whether be not less than (being namely more than or equal to) this queue wait time.If not, represent that femtocell thereof 13 cannot in wait time limit D
qCI (110)interior process request signal 110, then processing unit 133 throws aside request signal 110; If so, represent that femtocell thereof 13 can in wait time limit D
qCI (110)interior process request signal 110.
Separately answer expositor, at Long Term Evolution (LoneTermEvolution; LTE) in specification, for the wireless network resource demand of different kenel, two large kinds can be divided into, be respectively and ensure bit rate (GuaranteedBitRate; GBR) service request and non-guaranteed bit rate (non-GuaranteedBitRate; Non-GBR) service request.Specifically, namely service request as voice service belongs to the service request ensureing bit rate, because voice service must use a specific frequency range to transmit package incessantly, compared with interruption when cannot allow package transmission, therefore femtocell thereof must be given security the wireless network resource of bit rate; Relatively, namely the service request of service on net belongs to the service request of non-guaranteed bit rate, the transmission of webpage package is compared with interruption when can allow package transmission, namely webpage package does not need continual transmission, as long as transmit complete within the special time cycle, therefore femtocell thereof can be given security the wireless network resource of bit rate.
In addition, according to the specification of LTE, according to the service quality (QoS) that request signal is asked, can be subdivided into nine priority (priority) grades again, different priority levels corresponds to different data transmission rate (datarate) demands and postpones to limit.Therefore, according to the specification of LTE, each request signal priority level just can be sorted out.
The processing unit 133 of femtocell thereof 13 in judging its frequency range that request signal 110 can be provided to ask and service quality rating, and can in wait time limit D
qCI (110)after interior process request signal 110, just by request signal 110 scheduling in this queue.Then, processing unit 133 is according to the priority level of each request signal in this queue, pick out the request signal that a priority level is higher, and the ID of femtocell thereof 13 self is additional to the higher request signal of this priority level, and by Transmit-Receive Unit 131, request signal higher for this priority level is sent to micro base station management device 15, can learn that its request signal received is from femtocell thereof 13 in order to do micro base station management device 15, and carry out follow-up wireless network resource distribution.
In the present embodiment, request signal 110 and interference Figure 130 are sent to micro base station management device 15 by processing unit 133, micro base station management device 15 is then described in detail in detail below and how carries out wireless network resource distribution.Head answers expositor, and in the present embodiment, network system 1 adopts orthogonal frequency division multi-task to access (OrthogonalFrequencyDivisionMultipleAccess; OFDMA) wireless communication system standards, OFDMA is a kind of multiple access framework in conjunction with frequency domain and time domain; Therefore, under the framework of OFDMA, as long as by by distribution suitable on frequency domain and time domain for wireless network resource, just interfering with each other between different users's signal can be avoided.
In order to wireless network resource is carried out, frequency domain and time domain are distributed, first must define a resource block (ResourceBlock; RB).Specifically, a resource block refers to the unit frequency range on frequency domain and the unit interval in time domain; For example, in the present embodiment, each resource block is defined as the 2Mbps (Megabitspersecond) on frequency domain, and 0.1 microsecond (microsecond in time domain; Ms), that is a resource block refer to frequency range 0.1 microsecond that can use 2Mbps.Accordingly, the wireless network resource distribution that micro base station management device 15 is carried out is the distribution carrying out resource block.
Generally speaking, micro base station management device 15 has multiple resource block, and in order to manage multiple femtocell thereof, each femtocell thereof can receive the request signal that one or more user's device sends, the interference figure that received request signal and its are set up is sent to micro base station management device 15 by each femtocell thereof, and micro base station management device 15 just distributes these resource block to each request signal according to the interference figure of the request signal received and each femtocell thereof.
In the present embodiment, the Transmit-Receive Unit 151 of micro base station management device 15 is after reception request signal 110 and interference Figure 130, just request signal 110 and interference Figure 130 are sent to processing unit 153, processing unit 153 then can distribute to an available resource blocks quantity m of request signal 110 according to interference Figure 130 statistics.Specifically, adjacent domain due to femtocell thereof 13 has possibility causes interference femtocell thereof A-E with it, therefore micro base station management device 15 must according to interference Figure 130, get rid of femtocell thereof A-E use and the resource block of interference can be caused, to count available resource blocks quantity m with femtocell thereof 13.
