Detailed description of the invention

Below in conjunction with Figure of description and specific embodiment technical scheme done and further elaborate.Embodiment of the method one:

As it is shown in figure 1, the present embodiment provides a kind of information processing method, it is applied in base station；Described method includes:

Step S110: random access resource is divided into the first random access resource group and the second random access resource group；Wherein, described first random access resource group is for the Stochastic accessing of first kind subscriber equipment；Described second random access resource group is for the Stochastic accessing of Equations of The Second Kind subscriber equipment；

Step S120: obtain first random access parameter corresponding with described first random access resource group；Obtain second random access parameter corresponding with described second random access resource group；

Step S130: send described first random access parameter to described first kind subscriber equipment, described second random access parameter is sent to described Equations of The Second Kind subscriber equipment, wherein, described first random access parameter is used for indicating the available described first random access resource group of described first kind subscriber equipment, and described second random access parameter is used for indicating the available described second random access resource group of described Equations of The Second Kind subscriber equipment.

Described first kind subscriber equipment can be common subscriber equipment, concrete such as normal user equipments such as 2G subscriber equipment, 3G subscription equipment and 4G subscriber equipmenies, described normal user equipments can also be defined as the subscriber equipment except described Equations of The Second Kind subscriber equipment.Described Equations of The Second Kind subscriber equipment can be the subscriber equipment only supporting the first bandwidth, for instance only support the eMTC subscriber equipment of 1.4MHz communication technology.

In the present embodiment the random sources that described base station configures is divided into two groups, is the first random access resource group and the second random access resource group respectively；Each random access resource group at least includes a resource for Stochastic accessing.

The first random access parameter corresponding to the first random sources group and the second random access parameter corresponding to the second random access resource group will be obtained respectively in the step s 120.Described first random access parameter can be the contents such as the identification information of the resource in described first random access resource group.Same described second random access parameter can be the contents such as the identification information of the resource in described second random access resource group.

Described first random access parameter and the second random access parameter is sent in step s 130 respectively to two kinds of subscriber equipment, thus can inform the random access resource that first kind subscriber equipment and Equations of The Second Kind subscriber equipment can adopt when Stochastic accessing, when so facilitating subsequent base stations to carry out Stochastic accessing according to subscriber equipment, the random access resource of employing determines the type of subscriber equipment, thus adopting corresponding down channel to send information to different types of subscriber equipment.

Concrete as, when the subscriber equipment that current Stochastic accessing is determined in base station is normal user equipments, it is mutual that described base station can adopt physical downlink control channel PDCCH and Physical Downlink Shared Channel PDSCH and normal user equipments to carry out the information such as business datum.When the subscriber equipment of the current Stochastic accessing determined when base station is eMTC subscriber equipment, it is mutual that described base station can adopt enhancement mode Physical Downlink Control Channel EPDCCH and Physical Downlink Shared Channel PDSCH and eMTC subscriber equipment to carry out the information such as business datum.

Summary, present embodiments provide a kind of method that can be used for different types of subscriber equipment Stochastic accessing, by the division to random access resource, different types of subscriber equipment can be made to adopt different random access-in resource access base station, and the type according to random access resource determines subscriber equipment, information is carried out mutual from the down channel and subscriber equipment that can select correspondence, from solving prior art after the access of eMTC subscriber equipment, the problem that eMTC subscriber equipment can not be carried out effective response by base station.

Embodiment of the method two:

Random access resource for subscriber equipment Stochastic accessing to base station at least includes the resource such as running time-frequency resource and pilot code.Described first random access resource group and described second random access resource group all at least include running time-frequency resource and pilot code in the present embodiment；At least one of described first random access resource group and the running time-frequency resource of described second random access resource group and pilot code is different.

Namely when communicating, described first random access resource group and the pilot code in described second random access resource group have with running time-frequency resource one different, that is, can be that described first random access resource group is different with the pilot code in described second random access resource group, running time-frequency resource is identical, or described first random access resource group is identical with the pilot code in described second random access resource group, running time-frequency resource is different, or described first random access resource group is different with the pilot code in described second random access resource group, running time-frequency resource is also different.

Concrete such as first kind subscriber equipment employing A group pilot code Stochastic accessing base station, described Equations of The Second Kind subscriber equipment adopts B group pilot code Stochastic accessing base station, even if two class subscriber equipmenies are in the same time with same class running time-frequency resource access base station, the group of the pilot code that base station uses according to the subscriber equipment Stochastic accessing of described two types determines the type of subscriber equipment.

Described running time-frequency resource includes frequency resource and time resource；At least one of running time-frequency resource difference and frequency resource and time resource is different.Specifically when as described in the first random access resource group with as described in the second random access resource group be distinctive in that running time-frequency resource is different time.As the first random access resource group employing be first frequency range Stochastic accessing for first kind subscriber equipment, what the second random access resource group adopted is second frequency range Stochastic accessing for Equations of The Second Kind subscriber equipment, then base station is when receiving the Stochastic accessing of subscriber equipment, and which frequency range the frequency band sent according to random access request is positioned to determine the type of subscriber equipment.

The present embodiment on the basis of embodiment of the method one, the concrete difference defined between the first random access resource group and the second random access resource group, have and realize easy advantage.

Embodiment of the method three:

Described step S130 comprises the steps that

Utilize and the first broadcast channel sends described first random access parameter to described first kind subscriber equipment；

Utilize and the second broadcast channel sends described second random access parameter to described Equations of The Second Kind subscriber equipment；

Described first broadcast channel is different from described second broadcast channel.

Different broadcast channels it is commonly configured with between base station and different types of subscriber equipment, the random access parameter oneself needing to receive to facilitate different types of subscriber equipment to determine in the present embodiment, is respectively adopted the different broadcast channel corresponding to first kind subscriber equipment and Equations of The Second Kind subscriber equipment to broadcast described first random access parameter and the second random access parameter.

Concrete as, when the normal user equipments that first kind subscriber equipment is described in embodiment of the method one, the broadcast channel that can send system message 2 is adopted to be carried in described system message 2 (SIB2) by described first random access parameter sent along with SIB2.

Meanwhile, owing to adopting broadcast channel to send described first random access parameter and the second random access parameter, so can conveniently reside in the multiple subscriber equipmenies in the community that described base station is formed to receive, without the transmission of per user equipment, it is thus possible to improve transmitting efficiency and reduce the power consumption of base station.

Embodiment of the method four:

As in figure 2 it is shown, described method also includes:

Step S140: receive the random access request that subscriber equipment sends；

Step S150: determine the type of described subscriber equipment according to the random access resource sending described random access request；Wherein, when sending the random access resource that described random access request is described first random access resource group, it is determined that described subscriber equipment is described first kind subscriber equipment；When sending the random access resource that described random access request is described second random access resource group, it is determined that described subscriber equipment is described Equations of The Second Kind subscriber equipment.

Subscriber equipment receives the random access parameter of correspondence from the broadcast channel of base station, and first kind subscriber equipment adopts the first random access resource group to send random access request to described base station；Equations of The Second Kind subscriber equipment adopts the second random access resource group to send random access request to described base station；After receiving described random access request, base station first determines whether which random access resource group the random access resource sending the described random access request of energy is belonging to, so that it is determined that go out the type of the subscriber equipment sending described random access request, when allowing this subscriber equipment Stochastic accessing, determine according to the device type of this subscriber equipment and carry out downlink communication for its suitable down channel and this subscriber equipment, thus can ensure that subscriber equipment is able to receive that the data that base station sends, thus the efficient communication carried out between base station and subscriber equipment.

Concrete as, normal user equipments adopts the first random access resource group Stochastic accessing, and base station adopts Physical Downlink Control Channel and Physical Downlink Shared Channel and normal user equipments to communicate；EMTC subscriber equipment adopts the second random access resource group Stochastic accessing, and base station adopts enhancement mode Physical Downlink Control Channel to enter to communicate with subscriber equipment with Physical Downlink Shared Channel.

Embodiment of the method five:

As in figure 2 it is shown, described method also includes:

Step S140: receive the random access request that subscriber equipment sends；

Described method also includes:

Record the Stochastic accessing condition information of described first kind subscriber equipment in the first appointment time, form the first Stochastic accessing condition parameter；

Record the Stochastic accessing condition information of described Equations of The Second Kind subscriber equipment in the described first appointment time, form the second Stochastic accessing condition parameter；

According to described first Stochastic accessing condition parameter and described second Stochastic accessing condition parameter, adjust described first random access resource group and random access resource that the second random access resource group includes.

The time that the described first appointment time can be pre-configured with for base station, it is also possible to be from peripheral hardware or from Man Machine Interface receive time.Described first to specify the time span of time can be the time spans such as 10 seconds, 30 seconds, 15 seconds or 1 minute or 2 minutes.

The Stochastic accessing demand of current first kind subscriber equipment and Equations of The Second Kind subscriber equipment whether can be suitable in the present embodiment as much as possible in order to ensure the random resource allocation between the first random access resource group and the second random access resource group, record is also specified the time for time quantum length with first by the present embodiment, record the Stochastic accessing situation of the first kind subscriber equipment in time quantum and Equations of The Second Kind subscriber equipment, carry out the random access resource of adaptive adjustment the first random access resource group and the second random access resource group.

Assume that the Stochastic accessing of subscriber equipment is all utilize the random access resource in random access resource group based on the Stochastic accessing of competition, then random access resource is more few, the request of the subscriber equipment participating in Stochastic accessing is more many, then the probability of the random access failure of subscriber equipment is more high；Obviously in order to improve the probability of success of Stochastic accessing, it is possible to by increasing the quantity of the random access resource in a random access resource group, reduce the competitive strength between subscriber equipment, improve the success rate of Stochastic accessing.

If the total quantity of the random access resource of described base station is certain in the present embodiment, if the random access resource number that the first random access resource group includes is many, then the random access resource number that the second random access resource group includes is just few.Herein, the random access resource of the first random access resource group at least includes the running time-frequency resource for Stochastic accessing and pilot code.If now, the random access request number of first kind subscriber equipment is few, and the random access resource of the first random access resource group is many, to cause that the random access resource being partly comprised in the first random access resource group is in idle state, and the random access request of Equations of The Second Kind subscriber equipment is many, and the random access resource of the second random access resource group is many, will cause that Equations of The Second Kind subscriber equipment is high because of the mortality of the few Stochastic accessing of random access resource；Obvious above-mentioned situation can cause that the resource of random access resource is not well utilized, and the subscriber equipment low meeting of Stochastic accessing success rate simultaneously causes the problems such as the experience sense of user is differed from.

Therefore in the present embodiment within the first appointment time, the Stochastic accessing condition information of first kind subscriber equipment and Equations of The Second Kind subscriber equipment will be added up respectively, form the first Stochastic accessing condition information and the second Stochastic accessing condition information.Described first Stochastic accessing condition information and the second Stochastic accessing condition information can be Stochastic accessing success rate or mortality, or can also is that the random access request number etc. of dissimilar subscriber equipment reacts first kind subscriber equipment and the current Stochastic accessing condition information of Equations of The Second Kind subscriber equipment.After the second Stochastic accessing condition information of the first Stochastic accessing condition information and Equations of The Second Kind subscriber equipment that obtain first kind subscriber equipment, determine the need for adjusting the random sources number that the first random access resource group and the second random access resource include, and how to adjust the first random access resource group and random access resource that the second random access resource group includes.Concrete as, in the first current appointment time, the first random access resource group has part random access resource to be in idle state, and random access resource in the second random access resource group is substantially not enough, cause that the Stochastic accessing success rate of Equations of The Second Kind subscriber equipment is low, this determines that needs to adjust the random access resource number included in the first random access resource group and the second random access resource group, concrete as, reduce random access resource that the first random access resource group includes to increase the random access resource number that the second random access resource group includes, to reach to optimize the random access resource distribution of base station, improve the Stochastic accessing success rate of Equations of The Second Kind subscriber equipment simultaneously.

Random access resource in the first random access resource group adjusted in the present embodiment and the second random access resource group could be at least one of the running time-frequency resource of Stochastic accessing and pilot code.

Embodiment of the method six:

As in figure 2 it is shown, described method also includes:

Step S140: receive the random access request that subscriber equipment sends；

Described method also includes:

Described random access resource includes the packet of N kind；Wherein, the proportion that the corresponding described second random access resource group of n packet accounts for total described random access resource is the n-th proportion；(n+1)th proportion is more than the n-th proportion；Described N is the integer of not little 2；Described n is not less than 1 and integer less than described N；

The number of resources that the described first random access resource group of described adjustment and the second random access resource group include, including:

According to described first Stochastic accessing condition parameter and described second Stochastic accessing condition parameter, select the one in the packet of described N kind.

The present embodiment is based on a kind of method above mentioned embodiment providing concrete random access resource adjusting the first random access resource group and the second random access resource group.

Random access resource is defined by described base station in advance in N and be grouped；The proportion of random access resource numbers different in the first random access resource group and the second random access resource group in each packet is different, and namely namely the random access resource of the first random access resource group and the second random access resource group accounts for the proportion of total random access resource group is different.

Concrete as, when the first random access resource group is different with the running time-frequency resource for Stochastic accessing included of the second random access resource group, then in the first random access resource group in n packet, running time-frequency resource is different than the first random access resource group running time-frequency resource in the proportion of running time-frequency resource in upper total random access resource and (n+1)th kind of packet than the proportion of running time-frequency resource in upper random access resource.

When in the first random access resource group with the second random access resource group for the pilot code of Stochastic accessing different time, then in the first random access resource group in n packet pilot code than the proportion of pilot code in upper total random access resource and in (n+1)th kind of packet the first random access resource group pilot code be different than the proportion of pilot code in upper random access resource.

When the pilot code for Stochastic accessing included of the first random access resource group and the second random access resource group and running time-frequency resource are all different, then in the first random access resource group in n packet pilot code and running time-frequency resource than the proportion of pilot code and running time-frequency resource in upper total random access resource and in (n+1)th kind of packet the first random access resource group pilot code and running time-frequency resource be different than the proportion of pilot code and running time-frequency resource in upper random access resource.

In the present embodiment in order to accelerate to adjust the adjustment process of the first random access resource group and the second random access resource, N kind packet mode will be formed in advance, and from N kind mode, select one of which when needs adjust, have and realize easy advantage.

In concrete implementation process, can also according to default functional based method, the random access resource in the first random access resource group and the second random access resource group is adjusted with pre-fixed step size, specifically when as described in pre-fixed step size be 2 time, disposable can increase by two random access resources in a random access resource group, and another random access resource group reduces by two random access resources.Obvious above-mentioned method of adjustment is full of one and realizes easy and that the speed of response is high alternative, but is not limited to said method.

Embodiment of the method seven:

As in figure 2 it is shown, described method also includes:

Step S140: receive the random access request that subscriber equipment sends；

Described method also includes:

The present embodiment is based on, in a upper embodiment, specifically defining the first access failure number that described first Stochastic accessing condition parameter is described first kind subscriber equipment；And the second access failure number that described second Stochastic accessing condition parameter is described Equations of The Second Kind subscriber equipment.

If what the random access resource of presently described base station adopted is m packet；Described m is the positive integer being not more than described N；

Described according to described first Stochastic accessing condition parameter with described second Stochastic accessing condition parameter, adjust described first random access resource group and number of resources that the second random access resource group includes, including:

When the ratio of described first access failure number and described second access failure number is more than the first ratio, m-x is selected to be grouped；

When the ratio of described first access failure number and described second access failure number is less than the second ratio, m+x is selected to be grouped；

Described x is for adjusting step-length, for being not less than the integer of 1.

When described x is equal to 1, if being currently the 2nd kind of packet, then what the first random access resource group after adjusting and the second random access resource group adopted will be the 1st kind is grouped or the 3rd kind of packet.

It is the packet of determining Stochastic accessing of the ratio according to the first access failure number and the second random access failure number in the present embodiment；Such determine packet taken into account first kind subscriber equipment and the Stochastic accessing of Equations of The Second Kind subscriber equipment simultaneously, to take into account the Stochastic accessing success rate of first user equipment and the second subscriber equipment.

In concrete implementation process, it is also possible to according to priority principle under ensureing the Stochastic accessing situation of subscriber equipment of a type, carry out the adjustment of the random access resource of the first random access resource group and the second random access resource group.Concrete as, current first specifies the access of preferential first kind subscriber equipment in the time, need the Stochastic accessing success rate ensureing first kind subscriber equipment more than some threshold value, can also only add up the first Stochastic accessing success rate or mortality of first kind subscriber equipment in the present embodiment, further according to the first Stochastic accessing success rate or mortality, dynamically adjust the random access resource of the first random access resource group and the second random access resource group.

Described ratio is the first random access failure number and the ratio of the second random access failure number in the present embodiment, when implementing, the Stochastic accessing success rate in order to ensure first kind subscriber equipment Equations of The Second Kind subscriber equipment is in the first value range, first random access failure ratio and the second random access failure ratio can be compared, it is thus achieved that the 3rd ratio.Described first random access failure ratio is: first kind subscriber equipment ratio between random access failure number and its total Stochastic accessing number within the first appointment time；Described second random access failure ratio is: Equations of The Second Kind subscriber equipment is the comparison of ratio between random access failure number and its total Stochastic accessing number within the first appointment time.

Described first ratio and described second ratio can be ratio set in advance in the present embodiment, and described first ratio and described second ratio can equal can not also wait.

When described first ratio and the second ratio are equal, namely represent when the ratio of described first access failure number and described second access failure number is more than the first ratio, select m-x to be grouped；When the ratio of described first access failure number and described second access failure number is less than the first ratio, m+x is selected to be grouped；When the ratio of described first access failure number with described second access failure number is equal to the first ratio, it is possible to the packet keeping current is constant；Certainly, when implementing, it is also possible to when described first access failure number is equal to the first ratio with described second access failure number, m-x packet or m+x packet are selected.

When described first ratio and the second ratio difference, described first ratio is more than described second ratio.As when the first ratio is equal to X；Second ratio is equal to Y；X>Y；X and Y is positive number.When the ratio of the first access failure number and described second access failure number is more than X, m-x is selected to be grouped.When the ratio of the first access failure number and described second access failure number is less than, during in Y, selecting m+x to be grouped.When the ratio of the first access failure number and described second access failure number is more than during in Y and less than X, it is possible to keep current group constant.

When specifically adjusting, if presently described m is equal to 1, represent to be currently the 1st kind of packet, even if the ratio of described first access failure number and described second access failure number is more than the first ratio, it is grouped also without way reselection m-x, current group now can be kept constant, namely still select m to be grouped.If presently described m is equal to N, even if toilet states the first access failure number ratio with described second access failure number less than the second ratio, selects m+x to be grouped also without way, current group now can also be kept constant, namely still select m to be grouped.

Summary, the present embodiment provides a kind of method specifically how adjusting the random access resource number included in the first random access resource group and the second random access resource group based on any of the above-described embodiment, has and realizes easy advantage.

Additionally, information processing method described in the present embodiment can carry out by iterative cycles, concrete as performed by the cycle, as with the first appointment time for a time quantum, each time quantum carries out once described adjustment.Assume N=8, namely represent that base station realizes defining 8 packets, statistics and the record of the first random access information and the second random access information is all carried out in each time quantum, dynamically adjust according to record result, and the first random access parameter after adjustment and the second random access parameter are issued to different types of subscriber equipment, so return circulation dynamically to adjust, it is ensured that first kind subscriber equipment and Equations of The Second Kind subscriber equipment all can access base stations can to carry out effective information mutual with base station.

A concrete example is provided: random access resource is divided into two resource groups below in conjunction with above-mentioned any embodiment, even a random access resource group shares N number of packet configuration (N can be 8), and sequence number can represent eMTC resource group from small to large for 0-N-1 and account for the proportion increase of total PRACH resource.

The first step: initial setting up: base station carries out random access resource group division, initial time selects the 0th packet；And this information of the 0th packet will be selected, issue normal user equipments by system message SIB, on the other hand by issuing eMTC user for the broadcast channel of eMTC subscriber equipment.System message is the message utilizing BCCH to send.Described information is in above-described embodiment the first random access parameter and the second random access parameter.Described SIB and the broadcast channel to eMTC subscriber equipment transmission message are preferably difference.When implementing, different distinguishing identifier can be sent in different message, make different types of subscriber equipment can be respectively received the first random access parameter and the second random access parameter, and determine which group random access resource of selection accesses according to the communication identifier carried together.Now, distinguishing identifier sent along from the first random access parameter and the second random access parameter is different.

Second step: after subscriber equipment and base station synchronization, and after decoding the information obtaining broadcast channel, learn that the running time-frequency resource configuration of random access resource and resource divide configuration.If normal user equipments, then in the resource give domestic consumer, randomly choose one carry out random access resource, if eMTC subscriber equipment, then in the random access resource group of eMTC, randomly choose one carry out random access resource giving.

3rd step: base station is according to the random access request received, and the pilot code used according to it and/or running time-frequency resource determine the type of subscriber equipment.If eMTC subscriber equipment, then go to the 4th step, if normal user equipments then goes to the 5th step.

4th step: base station carries out the response to described random access request by EPDCCH and PDSCH on the frequency domain shared by the random access request of eMTC, namely adopts described EPDCCH and PDSCH to send accidental access response, and sends Msg3 to base station.

5th step: domestic consumer is carried out the response of regulation in R12 agreement namely PDCCH and PDSCH by base station；Namely described PDCCH and PDSCH is adopted to send accidental access response.

6th step: subscriber equipment checks the accidental access response RAR (RandomAccessResponse) that base station sends, and sends response (Msg3) to base station.

7th step: the base station Msg3 according to relative user equipment, responds and sends response message.Same is send response message by EPDCCH and PDSCH for eMTC user, is that PDCCH and PDSCH sends response message for normal user equipments.In statistics a period of time, the access request of (such as 10s) eMTC subscriber equipment and normal user equipments unsuccessfully counts and domestic consumer's access request unsuccessfully counts that then to think that the multi-upstream access of user unsuccessfully counts without user uplink access request be 0 respectively, and according to following criterion self-adaptative adjustment: when the statistics unsuccessfully counted, it is possible to the ID according to carrying in Msg3 is added up.

If the base station find that eMTC subscriber equipment random access failure number of users than upper normal user equipments random access failure number be more than or equal to certain threshold value (such as 2), then random access resource division grouping serial number adds 1, if having arrived maximum N-1, keeps.If the base station find that eMTC user sets random access failure number of users sets random access failure number less than certain threshold value (such as 0.5) than upper domestic consumer, then random access resource division grouping serial number subtracts 1, if having arrived minima 0, keeps.

The information that random access resource division after changing is grouped is informed to all subscriber equipmenies in base station range, for eMTC subscriber equipment then by the broadcast channel for eMTC, for normal user equipments, then passes through SIB.

Repeating the second to seven steps, base station self-adaptative adjustment PRACH resource divides configuration.
