Description

Business transmitting method and device
Technical field
The present embodiments relate to field of communication technology more particularly to a kind of business transmitting methods and device.
Background technique
IPTV (Internet Protocol Television, network protocol television) business is a kind of Medium, to the skill of the UE such as mobile phone, computer and DTV STB (User Equipment, user equipment) transmission business Art.Specifically, when IPTV access net use wireless access way, and using CPE (Customer Premise Equipment, Customer terminal equipment) carry out " last one kilometer covering " when, content operator sets program source contents by gateway, base station Preparation is sent to cpe end, then, sends its UE connected for IPTV service by CPE, corresponding UE terminal receives the business and solves Code plays corresponding video.
Wherein, when base station is when emitting wireless signal, transmission range is longer between base station and UE, the loss of signal and dry It disturbs also bigger, also, shelter may be there is also in signals transmission, therefore, the CPE institute in cell edge is received Signal quality is usually poor, for the QoS (Quality of Service, service quality) for the poor CPE that ensures signal quality, When so, to the CPE transmission services, need to consume more Internet resources, for example, higher transmission power.
In general, base station passes through the transmission mode of multicast to CPE transmission services, specifically, multicast is the biography of point to multi--point Defeated mode, in transmission services, base station is a and the business data packet replicated is same by business datum packet replication to be sent When sent to more CPE.It can be seen that using the transmission mode transmission services of multicast, business that base station is sent to each CPE Data packet is with portion, and therefore, the Internet resources distributed are also fixed and invariable.And base station is generally according to most of CPE's Signal quality distributes Internet resources, and therefore, using the transmission mode of multicast, the QoS of the preferable CPE of signal quality can guarantee, And the QoS of the poor CPE of signal quality will be poor, for example, received error code of service rate is higher, so as to cause UE without Method normal play corresponding video, the usage experience of user are also poor.
Summary of the invention
The embodiment of the invention provides a kind of business transmitting method and devices, to solve to carry out multicast biography using wireless network When defeated, the QoS of the poor CPE of signal quality poor problem.
In a first aspect, the embodiment of the invention provides a kind of business transmitting methods, this method comprises: in IPTV service, Each CPE under wireless signal covering sends service request to the base station for emitting the wireless signal, when base station receives target When the service request of CPE, the channel state information parameters and service identification of target CPE are read from service request, it is then possible to By the relationship of channel state information parameters and the first preset threshold, the signal quality of target CPE is determined, and then determine target The business of CPE transmits strategy.
Specifically, the first preset threshold is what the Internet resources according to needed for different channels state information parameters were set, when When the channel state information of target CPE is greater than the first preset threshold, it is believed that the signal quality of target CPE is preferable, can be by target CPE is as service CPE；When the channel state information of target CPE is less than the first preset threshold, then it is assumed that the signal of target CPE Second-rate, base station can concentrate the relaying CPE for selecting a service CPE as target CPE from service CPE, and control relaying CPE is to target CPE transmission services.Wherein, the service identification for relaying CPE is identical as the service identification of target CPE.
Using this implementation, base station can determine the letter of target CPE by the channel state information parameters of target CPE Number quality, in turn, when the signal quality of target CPE is poor, the preferable CPE of a base station selected signal quality is target CPE Junction traffic, to add relay on the basis of original signal network, the CPE that can ensure signal quality poor receives industry The QoS of business saves Internet resources.
With reference to first aspect, in a first possible implementation of that first aspect, base station can receive every clothes When the service request of business CPE, the service identification and channel state information parameters of respective service CPE are read from service request, so Afterwards, base station can filter out service identification all service CPEs identical with the service identification of target CPE, and form service to be selected CPE collection concentrates the selection maximum service CPE to be selected of channel state information parameters from the service CPE to be selected, as target in turn The relaying CPE of CPE.
Using this implementation, base station can precisely, efficiently determine the relaying CPE of target CPE, so as to improve industry The efficiency of business transmission.
With reference to first aspect, in a second possible implementation of that first aspect, base station can also be supported in target CPE When ProSe function, running time-frequency resource and temporary identifier are distributed for target CPE, then, it is wide that the running time-frequency resource can be used in target CPE Existing signal is broadcast, and temporary identifier is carried in discovery signal, and base station maintenance temporary identifier pass corresponding with service identification System.
At the same time, there are all alternative CPE of relaying permission, send relaying to base station according to some cycles always and ask It asks.Since every alternative CPE for being not alternative CPE concentration has the ability to provide relay services, base station is receiving every After the relay request of alternative CPE, its channel state information parameters and service identification can be read, and according to channel state information Parameter filters out service CPE collection from alternative CPE concentration.
Further, since the service CPE that current and not all service CPE is concentrated is required to provide relay services, furthermore, it is desirable to The service identification of the target CPE relayed has stored in base station, therefore, base station can read stored in corresponding relationship it is every The corresponding temporary identifier of a service identification, and each temporary identifier is distributed into corresponding service and identifies corresponding service CPE, it obtains Relay CPE collection.In turn, every relaying CPE monitoring discovery signal of triggering relaying CPE collection, meanwhile, it compares respectively self-contained Temporary identifier in temporary identifier and discovery signal, when the temporary identifier of relaying CPE is identical as the temporary identifier in discovery signal When, relaying CPE of the relaying CPE as corresponding CPE.
Using this implementation, different temporary identifiers is distributed for different service identifications in base station, and in selecting after CPE When, using temporary identifier as reference frame, to not use service identification in information interactive process, guarantee the hidden of service identification Private and safety.
With reference to first aspect, in first aspect in the third possible implementation, in the temporary identifier that base station is distributed It is provided with timestamp, which is used to record the effective time of the temporary identifier, and in effective time, which can be with It uses, after length expires when active, temporary identifier failure, at this point, target CPE can be sent to base station obtains new temporary identifier Request, it is that target CPE distributes new temporary identifier that base station, which can respond the request, and at the same time, base station is by phase in corresponding relationship The corresponding temporary identifier of service identification is answered to be revised as new temporary identifier.
It using this implementation, relays CPE and is matched with target CPE by temporary identifier, and each temporary identifier is only Whithin a period of time effectively, it to can not only guarantee the normal matching of relaying CPE and target CPE, but also can be improved each The safety of a CPE associated traffic data.
With reference to first aspect, in the 4th kind of possible implementation of first aspect, base station may determine that the letter of target CPE Whether channel state information parameter is greater than the second preset threshold, presets if the channel state information parameters of target CPE are greater than second Threshold value illustrates that the signal quality of target CPE is relatively preferable, even if the resource that distribution is less, it is also ensured that business transmission Therefore QoS can control relaying CPE by way of multicast to target CPE transmission services；If the channel status of target CPE Information parameter, if illustrating to distribute less resource, may not can guarantee the QoS of business transmission less than the second preset threshold, therefore, Relaying CPE be can control by way of unicast to target CPE transmission services.
Using this implementation, base station can also relay CPE's according to the network performance of relaying CPE and target CPE, control Service transferring mode, thus on the basis of guaranteeing the QoS of target CPE, so that the embodiment of this programme is more flexible, in turn Applicability is wider.
Second aspect, the embodiment of the invention also provides a kind of business transmitting method, the realization processes and first of this method Aspect and each implementation of first aspect are similar, but this method protects this programme from another dimension.
Specifically, the attenuation degree and transmission range of signal are proportional due in wireless transmission, and therefore, second aspect Method, with physical distance be with reference to dimension.When receiving the service request of target CPE, base station is read from service request The location information and service identification of target CPE, and according to positional information calculation target CPE at a distance from base station, if the two Distance is greater than the first preset threshold, illustrates that the signal quality of target CPE is poor, can be that target CPE transmits industry by relaying CPE Business；If the distance of the two less than the first preset threshold, illustrates that the signal quality of target CPE is preferable, can using target CPE as Service CPE.
Using this implementation, base station can determine the signal quality of target CPE by target CPE at a distance from base station, In turn, when the signal quality of target CPE is poor, the preferable CPE of a base station selected signal quality relays industry for target CPE Business, to add relay on the basis of original signal network, the CPE that can ensure signal quality poor receives business QoS saves Internet resources.
Other possible implementations of second aspect, the realization process of second aspect is similar to first aspect, but second In other possible implementations of aspect, the signal quality of target CPE is determined, specifically at a distance from base station by target CPE , details are not described herein again for the embodiment of the present invention.

Specific embodiment
With reference to the accompanying drawing, the embodiment of the present invention is described.
Wherein, since to before CPE transmission services, base station needs to be business data packet distribution money according to the performance of CPE Source, therefore, when passing through the transmission mode transmission services of multicast, for the QoS for the relatively poor CPE that ensures signal quality, base Resource can be distributed according to the worst CPE of signal quality by standing, to be necessarily required to increase distributed resource.However, most of Resource needed for CPE may be relatively fewer, and therefore, this kind of mode of operation not only causes the waste of base station resource, moreover, to neighbouring The interference that the CPE in region is generated also will increase.
In view of this, proposing the business transmitting method of the embodiment of the present invention, mentioned referring to Fig. 1, Fig. 1 for the embodiment of the present invention The method flow diagram of the business transmitting method of confession.The embodiment of the present invention is applied in base station side, can not change base station resource point On the basis of matching, the QoS for the received business of poor CPE that ensures signal quality.The present embodiment the following steps are included:
Step S101 reads the channel state information parameters and service identification of target CPE from service request.
Wherein, in IPTV service, when UE program request IPTV service, each CPE under wireless signal covering is to hair The base station for penetrating the wireless signal sends service request, may include in service request the location information of corresponding CPE, identity information, Service identification and channel state information parameters.Wherein, the identity information of CPE may include the IP address (Internet of CPE Protocol Address, internet protocol address), port numbers or MAC Address (Media Access Control, physically Location)；Service identification can be channel multicast group address；Channel state information parameters include CQI (Channel Quality Indicator, channel quality instruction), for indicating the channel quality of the CPE.
Based on this, base station, can be using the CPE as current target after the service request for receiving each CPE CPE reads the channel state information parameters and service identification of target CPE, from its service request to believe according to channel status Breath parameter judges whether target CPE needs other CPE to provide relay services, and selects matched CPE according to service identification.
Whether step S102 detects channel state information parameters less than the first preset threshold.
Wherein, before the business transmission strategy for determining target CPE, base station should determine the signal matter of target CPE first Amount, if the signal quality of target CPE is relatively preferable, target CPE can be directly by base station transmission services, also, are somebody's turn to do Target CPE can provide sufficiently large gain also for business data packet, and then provide the service of relay services as to other CPE CPE.And if the signal quality of target CPE is relatively poor, target CPE not can guarantee reliable business and receive, institute With this programme will select the relatively preferable CPE of a signal quality for target CPE junction traffic.
Since the channel state information parameters of target CPE indicate the current channel conditions of target CPE, usually in general, Channel status is good, so that the received signal quality of target CPE is preferable, it is on the contrary then poor.
Based on this, in the present embodiment, when can be transmitted according to business, the money of network needed for channel state information parameters Source presets the first threshold of channel state information parameters, in turn, it can be determined that the channel state information parameters of target CPE Whether first preset threshold is less than, if the channel state information parameters of target CPE are less than first preset threshold, then it is assumed that Target CPE needs lower modulation coding scheme and higher transmission power to transmit data, can be target by relaying CPE CPE transmission services；And if the channel state information parameters of target CPE are greater than first preset threshold, then it is assumed that target CPE's Signal quality is preferable, and the demand to base station resource is relatively fewer, to will not lead to unreasonable Network resource allocation, can incite somebody to action Target CPE is as service CPE.
It should be pointed out that the first preset threshold is not a specific numerical value, but the value set according to demand is implemented, Therefore, the embodiment of the present invention is not specifically limited the first preset threshold.
Step S103 concentrates the relaying CPE for selecting a service CPE as target CPE from service CPE.
Wherein, by the description of above-mentioned steps it is found that the CPE that channel state information parameters are greater than the first preset threshold is service CPE, therefore, in the present solution, service CPE collection is the set for the CPE that channel state information parameters are greater than the first preset threshold；Relaying CPE is the service CPE for other CPE transmission services.
When the channel state information parameters of target CPE are less than first preset threshold, the business of target CPE transmits strategy It is that, by relaying CPE transmission services, therefore, base station should concentrate the relaying CPE of selection target CPE from service CPE.This programme In, it can be, but not limited to the relaying CPE for concentrating selection target CPE from service CPE by two ways, regardless of using which kind of side Formula, relaying service identification corresponding to CPE should be identical as the service identification of target CPE, and in turn, relaying CPE can be for certainly The business of body provides sufficiently large gain, and is transferred to target CPE.
Specifically, in an alternate embodiment of the present invention where, base station can be asked in the business for receiving every service CPE When asking, the service identification and channel state information parameters of respective service CPE are read from service request, then, base station can sieve Service identification all service CPEs identical with the service identification of target CPE are selected, and form service CPE collection to be selected, in turn, from The service CPE to be selected concentrates the selection maximum service CPE to be selected of channel state information parameters, the relaying CPE as target CPE.
Certainly, it should be pointed out that service CPE to be selected concentration may only include a service CPE to be selected, at this point, this to Choosing service CPE is the maximum service CPE to be selected of channel state information parameters.If service CPE to be selected concentrates channel status letter Ceasing the maximum service CPE to be selected of parameter is more, then one can be randomly choosed from the maximum service CPE to be selected of information parameter Relaying CPE of the service CPE to be selected as target CPE.
In addition, base station can also trigger target CPE broadcast discovery signal in another alternative embodiment of the invention, And out-trunk CPE collection is screened, then, every relaying CPE that relaying CPE is concentrated is needed with current respectively by monitoring discovery signal The CPE to be relayed is matched, and finally, relaying CPE concentrates every relaying CPE to establish one by one with the CPE relayed is currently needed With relationship.
Specifically, matching for target CPE can be read when base station determines that target CPE needs other CPE to provide relay services Confidence breath, and judge whether target CPE supports ProSe function (adjacent service) by its configuration information, if target CPE is supported ProSe function, eNB send the instruction of broadcast discovery signal to target CPE.It wherein, include eNB in the instruction of broadcast discovery signal For the running time-frequency resource of the transmission discovery signal of target CPE distribution, and the temporary identifier for indicating service identification.Wherein, should The service identification of temporary identifier and target CPE are in corresponding relationship, and the base station stored corresponding relationship.
After target CPE receives the instruction of broadcast discovery signal, broadcast discovery signal, and corresponding temporary identifier is carried It was found that in signal.Wherein, it should be noted that the CPE of current institute relaying in need passes through same radio resource broadcast and finds Signal, therefore, if every CPE carries service identification in discovery signal, the privacy of service identification and safety will Threat is received, this is based on, different temporary identifiers is distributed for different service identifications in base station, and in selecting when CPE, to face When mark be used as reference frame, thus in information interactive process do not use service identification, guarantee service identification privacy and Safety.
In addition, in practical applications, CPE is safeguarded by different operators, and, it is not mentioned in the default privilege of every CPE For the permission of relay services.When respective operator is wanted to promote safeguarded CPE, it can open safeguarded CPE's manually Relay services permission, and after opening relay services permission, CPE periodically sends relay request to eNB.Wherein, the relaying Request may include location information, identity information, service identification and the channel state information parameters of the CPE.And base station is receiving To after relay request, by the corresponding CPE of every relay request alternately CPE, alternative CPE collection is obtained.
Since the relay services permission of CPE is open-minded by operator, and operator it is not intended that safeguarded CPE signal quality Whether relay services are enough to provide, so, alternative CPE concentrates the existing CPE for being enough to provide relay services, also has in can not providing After the CPE of service, therefore, base station can read the channel state information parameters of each CPE after obtaining alternative CPE collection, To filter out service CPE collection in alternative CPE collection according to channel state information parameters.
Further, the CPE for currently needing to relay may be one more than, and the industry that the CPE for needing to relay is mutual Business mark may be different, and the corresponding temporary identifier of each service identification, and base station maintenance service identification and temporary identifier Corresponding relationship.So base station can read the corresponding temporary identifier of each service identification stored in corresponding relationship, and will be every A temporary identifier distributes to corresponding service and identifies corresponding service CPE, obtains relaying CPE collection, then, to the every of relaying CPE collection Platform relays the radio resource of CPE distribution discovery signal.
Relay services are provided since which platform target CPE every relaying CPE currently can not determine to, it is receiving After radio resource, every relaying CPE passes through radio resource monitoring discovery signal, and compares self-contained interim mark respectively Know with the temporary identifier in discovery signal, when the temporary identifier for relaying CPE is identical as the temporary identifier found in signal, in this After relaying CPE of the CPE as corresponding CPE, identical, the interim mark in entrained temporary identifier and target CPE discovery signal Know identical relaying CPE, as the relaying CPE of target CPE.
It can be seen that this programme relays CPE, energy by channel state information parameters and service identification, for target CPE selection It is enough to increase new relay on original network, so as to multiplexed network resource, improve the QoS of target CPE.
In addition, the safety in order to guarantee business transmission, is provided with timestamp in the temporary identifier that base station is distributed, this when Between stab effective time for recording the temporary identifier, for example, effective time is 10 minutes.In effective time, the interim mark Knowledge can be used, and after length expires when active, temporary identifier failure newly be faced at this point, target CPE can send to obtain to base station When the request that identifies, it is that target CPE distributes new temporary identifier that base station, which can respond the request, and at the same time, base station is closed corresponding Corresponding service identifies corresponding temporary identifier and is revised as new temporary identifier in system.
It can be seen that relaying CPE is matched with target CPE by temporary identifier, and is each faced using this implementation When mark only whithin a period of time effectively, and can also to can not only guarantee to relay the normal matching of CPE and target CPE Enough improve the safety of each CPE associated traffic data.
Step S104, control relay CPE to target CPE transmission services.
On the basis of above-mentioned steps, after the relaying CPE for determining target CPE, relaying CPE can control to target CPE Transmission services.
Certainly, relaying CPE can by WLAN (Wireless Local Area Networks, Wireless LAN) or Person 3G/4G network is to target CPE transmission services, since WLAN performance is relatively stable, if relaying CPE is used WLAN can also control the industry of relaying CPE according to the channel state information parameters of target CPE to target CPE transmission services, base station Business transmission mode.
Specifically, base station may determine that whether the channel state information parameters of target CPE are greater than the second preset threshold, if The channel state information parameters of target CPE are greater than the second preset threshold, illustrate that the signal quality of target CPE is relatively preferable, even if Multicast does not provide retransmission mechanism, it is also ensured that therefore the QoS of business transmission can control relaying CPE by way of multicast To target CPE transmission services；If the channel state information parameters of target CPE less than the second preset threshold, illustrate channel at this time State is poor, may not can guarantee the QoS of business transmission, therefore, can control relaying CPE by way of unicast to target CPE transmission services.
Wherein, when the transmission services by the way of multicast, relaying CPE is for target CPE one MAC layer multicast of distribution Location, and inform its BSSID (Basic Service Set ID) and channel used, when relaying CPE receives the industry of base station transmission When data packet of being engaged in, MAC header is added for business data packet, and the business data packet for adding MAC header is transmitted to target CPE.Wherein, Address 1 in the MAC header of addition is set as MAC layer multicast address, and address 2 is set as the MAC Address of relaying CPE, and address 3 is arranged For multicast source address.
When the transmission services by the way of unicast, BSSID and channel used are informed target CPE by relaying CPE, and are recorded The MAC Address of target CPE adds MAC header when relaying CPE receives the business data packet of base station transmission for business data packet, And the business data packet for adding MAC header is transmitted to target CPE.Wherein, the address 1 in the MAC header of addition is set as target CPE MAC Address, address 2 be set as relaying CPE MAC Address, address 3 is set as multicast source address.
In addition, it should be noted that, relaying CPE is when to target CPE transmission services, it is also necessary to relaying CPE connection UE transmission services relay the CPE also available terminal quantity for needing transmission services, and/or, the quantity of contention channel works as end Quantity is held, and/or, when the quantity of contention channel is greater than certain value, then industry is transmitted to target CPE and UE by the way of multicast Business；Conversely, work as terminal quantity, and/or, when the quantity of contention channel is less than the value, then to target CPE by the way of unicast With UE transmission services.Specifically, multicast transmission mode and unicast transmission mode are detailed in foregoing description, the embodiment of the present invention is herein not It is described in detail again.
It can be seen that base station can also be according to the network performance of relaying CPE and target CPE, control relaying CPE in this programme Service transferring mode, thus on the basis of guaranteeing the QoS of target CPE so that the embodiment of this programme is more flexible, into And applicability is wider.
By the description of the present embodiment it is found that the business transmitting method of the embodiment of the present invention, is believed by the channel status of CPE Breath, can determine the signal quality of the CPE, when the signal quality of CPE is poor, using the relatively good CPE of signal quality as Trunking, thus by increasing new relay on original network, with obtained by relaying transmission gain and So that the high efficiency of transmission of original multicast, and then network side resource consumption can be reduced, and the poor CPE that ensures signal quality connects The QoS of receipts business.
