Step S120: the first random access parameter corresponding with the first random access resource group is obtained；Obtain with Corresponding second random access parameter of the second random access resource group；

S130: Xiang Suoshu first kind user equipment of step sends first random access parameter, and the second class of Xiang Suoshu is used Family equipment sends second random access parameter, wherein first random access parameter is used to indicate the first kind and uses The available first random access resource group of family equipment, second random access parameter are used to indicate second class and use The available second random access resource group of family equipment.

The first kind user equipment can be common user equipment, it is specific such as 2G user equipment, 3G subscription equipment and 4G The normal user equipments such as user equipment, the normal user equipments can also be defined as in addition to the second class user equipment User equipment.The second class user equipment can be the user equipment for only supporting the first bandwidth, such as only support that 1.4MHz is logical The eMTC user equipment of letter technology.

The random sources that the base station configures are divided into two groups in the present embodiment, are the first random access resource group respectively With the second random access resource group；Each random access resource group includes at least the resource for being used for random access.

Corresponding first random access parameter of the first random sources group and second will be obtained respectively in the step s 120 at random Corresponding second random access parameter of access-in resource group.First random access parameter can be first random access resource The contents such as the identification information of the resource in group.Same second random access parameter can be second random access resource The contents such as the identification information of the resource in group.

In step s 130 respectively to two kinds of user equipment send first random access parameter and second with Machine access parameter can thus inform what first kind user equipment and the second class user equipment can be used in random access The random access resource that random access resource uses when so that it is convenient to which subsequent base stations are according to user equipment progress random access is come really The type of user equipment is determined, to send information to different types of user equipment using corresponding down channel.

Specifically such as, when base station determines that the user equipment of current random access is normal user equipments, the base station can To carry out business datum using physical downlink control channel PDCCH and Physical Downlink Shared Channel PDSCH and normal user equipments Etc. information exchanges.When the user equipment for the current random access that base station is determined is eMTC user equipment, the base station can be with Business is carried out using enhanced Physical Downlink Control Channel EPDCCH and Physical Downlink Shared Channel PDSCH and eMTC user equipment The information exchanges such as data.

In summary, a kind of method that can be used for different types of user equipment random access is present embodiments provided, is led to The division to random access resource is crossed, different types of user equipment can be made to use different random access-in resource access base station, And user equipment is determined according to the type of random access resource, from corresponding down channel and user equipment can be selected to carry out Information exchange, after it can solve eMTC user equipment access in the prior art, base station cannot carry out eMTC user equipment effective The problem of response.

Embodiment of the method two:

Random access resource for user equipment random access to base station includes at least running time-frequency resource and pilot code etc. Resource.The first random access resource group and the second random access resource group include at least time-frequency in the present embodiment Resource and pilot code；The running time-frequency resource and pilot code of the first random access resource group and the second random access resource group At least one is different.

Pilot tone i.e. when being communicated, in the first random access resource group and the second random access resource group Code with running time-frequency resource have one it is different, that is to say, that can be the first random access resource group and described second with Pilot code in machine access-in resource group is different, running time-frequency resource is identical or the first random access resource group and described second with Pilot code in machine access-in resource group is identical, running time-frequency resource is different or the first random access resource group and described second with Pilot code difference in machine access-in resource group, running time-frequency resource are also different.

Specific such as first kind user equipment uses A group pilot code random access base station, and the second class user equipment uses B Group pilot code random access base station, even if two class user equipmenies are in the same time with same class running time-frequency resource access base station, base station The group of the pilot code used according to the user equipment random access of two type determines the type of user equipment.

The running time-frequency resource includes frequency resource and time resource；Running time-frequency resource difference, that is, frequency resource and time resource At least one is different.The specific difference as worked as the first random access resource group and the second random access resource group When being running time-frequency resource difference.As the first random access resource group using the first frequency range for first kind user equipment Random access, the second random access resource group are used for the random access of the second class user equipment using the second frequency range, then base It stands in the random access for receiving user equipment, which frequency range the frequency band sent according to random access request is located to determine The type of user equipment.

The present embodiment on the basis of embodiment of the method one, specifically define the first random access resource group and second with Difference between machine access-in resource group has the advantages that realize easy.

Embodiment of the method three:

The step S130 can include:

First random access parameter is sent to the first kind user equipment using on the first broadcast channel；

Second random access parameter is sent to the second class user equipment using on the second broadcast channel；

First broadcast channel is different from second broadcast channel.

Different broadcast channels is commonly configured between base station and different types of user equipment, in the present embodiment in order to Different types of user equipment is facilitated to determine that oneself needs received random access parameter, is respectively adopted corresponding to first kind user The different broadcast channels of equipment and the second class user equipment broadcast first random access parameter and the second random access Parameter.

Specifically such as, when first kind user equipment is normal user equipments described in embodiment of the method one, use can be sent out The broadcast channel of system message 2 is sent to be carried on first random access parameter in the system message 2 (SIB2) and SIB2 It sends together.

At the same time, due to sending first random access parameter and the second random access parameter using broadcast channel, The multiple user equipmenies that can be conveniently resided in the cell that the base station is formed in this way receive, and do not have to the hair of per user equipment It send, so as to improve transmitting efficiency and reduce the power consumption of base station.

Embodiment of the method four:

As shown in Fig. 2, the method also includes:

Step S140: the random access request that user equipment is sent is received；

Step S150: the class of the user equipment is determined according to the random access resource for sending the random access request Type；Wherein, when sending the random access resource that the random access request is the first random access resource group, institute is determined Stating user equipment is the first kind user equipment；It is the second random access resource group when sending the random access request Random access resource when, determine the user equipment be the second class user equipment.

User equipment receives corresponding random access parameter from the broadcast channel of base station, and first kind user equipment uses First random access resource group sends random access request to the base station；Second class user equipment is provided using the second random access Source group sends random access request to the base station；After receiving the random access request, base station first determines whether to send energy The random access resource of the random access request be which random access resource group belonged to, so that it is determined that go out to send it is described with The type of the user equipment of machine access request, the equipment class when allowing the user equipment random access, according to the user equipment Type, which is determined, carries out downlink communication for its compatible down channel and the user equipment, ensures that user equipment can in this way The data for receiving base station transmission, to carry out the efficient communication between base station and user equipment.

Specifically such as, normal user equipments use the first random access resource group random access, and base station uses physical down control Channel and Physical Downlink Shared Channel processed are communicated with normal user equipments；EMTC user equipment is provided using the second random access Source group random access, base station is using enhanced Physical Downlink Control Channel and Physical Downlink Shared Channel and user equipment into logical Letter.

Embodiment of the method five:

As shown in Fig. 2, the method also includes:

Step S140: the random access request that user equipment is sent is received；

The method also includes:

The random access condition information of the first kind user equipment in the first specified time is recorded, first is formed and connects at random Enter condition parameter；

Record the random access condition information of the second class user equipment in first specified time, formed second with Machine accesses condition parameter；

According to the first random access condition parameter and the second random access condition parameter, adjustment described first with The random access resource that machine access-in resource group and the second random access resource group include.

First specified time can be the base station preconfigured time, be also possible to connect from peripheral hardware or from human-computer interaction The mouth received time.Whens the time span of first specified time can be 10 seconds, 30 seconds, 15 seconds or 1 minute or 2 minutes etc. Between length.

In the present embodiment in order to ensure random between the first random access resource group and the second random access resource group Whether resource allocation can be applicable in the random access demand of current first kind user equipment and the second class user equipment as far as possible, this Embodiment will also record the first kind user equipment and the using the first specified time as time quantum length, in record time quantum The random access situation of two class user equipmenies comes adjustment the first random access resource group and the second random access resource of adaptability The random access resource of group.

Assuming that the random access of user equipment is to be based on competition using the random access resource in random access resource group Random access, then random access resource is fewer, and the request for participating in the user equipment of random access is more, then user equipment with The probability of machine access failure is higher；Obviously it in order to improve the probability of success of random access, can be connect at random by increasing by one Enter the quantity of the random access resource in resource group, to reduce the competitive strength between user equipment, improve random access at Power.

If the total quantity of the random access resource of the base station is certain in the present embodiment, if the first random access provides The random access resource number that source group includes is more, then the random access resource number that the second random access resource group includes is just few.Herein, The random access resource of first random access resource group includes at least the running time-frequency resource and pilot code for random access.If this When, the random access request number of first kind user equipment is few, and the random access resource of the first random access resource group is more, will lead The random access resource that is partly comprised in the first random access resource group is caused to be in idle state, and the second class user equipment Random access request is more, and the random access resource of the second random access resource group is more, will lead to the second class user equipment because with The failure rate of the few random access of machine access-in resource is high；Obvious above situation will lead to the resource of random access resource not by very Good utilization, while the problems such as the low experience sense that will lead to user of user equipment random access success rate is by difference.

Therefore in the present embodiment within the first specified time, first kind user equipment will be counted respectively and the second class user sets Standby random access condition information forms the first random access condition information and the second random access condition information.Described first Random access condition information and the second random access condition information can be random access success rate or failure rate, or can be with Be random access request number of different type user equipment etc. reaction first kind user equipment and the second class user equipment currently with Machine accesses condition information.When the first random access condition information and the second class user equipment for obtaining first kind user equipment After second random access condition information, it is determined whether need to adjust the first random access resource group and the second random access resource Including random sources number, and how to adjust the first random access resource group and that the second random access resource group includes is random Access-in resource.Specifically such as, the first random access resource group has part random access resource to be in the first current specified time Idle state, and the random access resource in the second random access resource group is obviously not enough, leads to the second class user equipment Random access success rate is low, this is to determine to need to adjust in the first random access resource group and the second random access resource group to include Random access resource number, specifically such as, reduce the first random access resource group random access resource for including with increase by second with The random access resource number that machine access-in resource group includes to reach the random access resource distribution of optimization base station, while improving the The random access success rate of two class user equipmenies.

The random access in the first random access resource group and the second random access resource group adjusted in the present embodiment Resource can be at least one of running time-frequency resource and pilot code for random access.

Embodiment of the method six:

As shown in Fig. 2, the method also includes:

Step S140: the random access request that user equipment is sent is received；

The method also includes:

The random access resource includes the grouping of N kind；Wherein, corresponding second random access resource of n grouping The specific gravity of group Zhan total random access resource is the n-th specific gravity；(n+1)th specific gravity is greater than the n-th specific gravity；The N be not small 2 it is whole Number；The n is the integer not less than 1 and less than the N；

The number of resources for adjusting the first random access resource group and the second random access resource group and including, comprising:

According to the first random access condition parameter and the second random access condition parameter, the N kind point is selected One of group.

The present embodiment provide based on the above embodiment a kind of specific the first random access resource group of adjustment and second with The method of the random access resource of machine access-in resource group.

Random access resource is formd in N in advance in the base station and is grouped；First random access in each grouping The specific gravity of different random access resource numbers is different in resource group and the second random access resource group, i.e., namely first with The specific gravity of the total random access resource group of the random access resource Zhan of machine access-in resource group and the second random access resource group is different 's.

Specifically such as, when the first random access resource group and the second random access resource group include for random access When running time-frequency resource difference, then n grouping in the first random access resource group in running time-frequency resource than upper total random access resource When the first random access resource group running time-frequency resource is than in upper random access resource in the specific gravity of middle running time-frequency resource and (n+1)th kind of grouping The specific gravity of frequency resource is different.

When the first random access resource group in the second random access resource group be used for random access pilot code difference when, Then in the first random access resource group in n grouping pilot code than the specific gravity of pilot code in upper total random access resource and the The first random access resource group pilot code is different than the specific gravity of pilot code in upper random access resource in the grouping of n+1 kind.

When the pilot code for random access for including of the first random access resource group and the second random access resource group And running time-frequency resource it is different when, then pilot code and running time-frequency resource are more total than upper in the first random access resource group in n grouping In random access resource in the specific gravity of pilot code and running time-frequency resource and (n+1)th kind of grouping the first random access resource group pilot code and Running time-frequency resource is different than the specific gravity of pilot code and running time-frequency resource in upper random access resource.

In the present embodiment in order to accelerate adjust the first random access resource group and the second random access resource adjustment Journey will form N kind packet mode in advance, select wherein one group from N kind mode when needing to adjust, and have and realize simplicity The advantages of.

During concrete implementation, it can also be connect at random according to preset functional based method with pre- fixed step size adjustment first Enter the random access resource in resource group and the second random access resource group, it, can be with one specifically such as when the pre- fixed step size is 2 Secondary property increases by two random access resources in a random access resource group, and another random access resource group reduces two Random access resource.Obvious above-mentioned method of adjustment is full of one and realizes easy and high speed of response optional method, but not office It is limited to the above method.

Embodiment of the method seven:

As shown in Fig. 2, the method also includes:

Step S140: the random access request that user equipment is sent is received；

The method also includes:

The present embodiment is based in a upper embodiment, specifically defines that the first random access condition parameter is described first First access failure number of class user equipment；And the second random access condition parameter is the of the second class user equipment Two access failure numbers.

If it is m grouping that the random access resource of presently described base station, which uses,；The m is just whole no more than the N Number；

It is described according to the first random access condition parameter and the second random access condition parameter, adjust described the The number of resources that one random access resource group and the second random access resource group include, comprising:

When the ratio of the first access failure number and the second access failure number is greater than the first ratio, m- is selected X grouping；

When the ratio of the first access failure number and the second access failure number is less than the second ratio, m+ is selected X grouping；

The x is adjusting step, for the integer not less than 1.

When the x is equal to 1, if being currently the 2nd kind of grouping, the first random access resource group adjusted and second is at random What access-in resource group used will be the 1st kind of grouping or the 3rd kind of grouping.

It is to be determined according to the ratio of the first access failure number and the second random access failure number at random in the present embodiment The grouping of access；It is such to determine that grouping has combined connecing at random for first kind user equipment and the second class user equipment Enter, to take into account the random access success rate of the first user equipment and second user equipment.

During concrete implementation, connecing at random for the user equipment of a type can also guaranteed according to priority principle In the case of entering, the adjustment of the random access resource of the first random access resource group and the second random access resource group is carried out.Specifically Such as, in current first specified time preferential first kind user equipment access, need to guarantee first kind user equipment at random connect Enter success rate greater than some threshold value, can also only count in the present embodiment the first random access of first kind user equipment at Power or failure rate, further according to the first random access success rate or failure rate, dynamic adjusts the first random access resource group and the The random access resource of two random access resource groups.

The ratio is the ratio of the first random access failure number and the second random access failure number, In in the present embodiment In order to guarantee that the random access success rate of first kind user equipment the second class user equipment is in the first range when specific implementation In value, the first random access failure ratio can be compared with the second random access failure ratio, obtain third ratio.Institute State the first random access failure ratio are as follows: first kind user equipment within the first specified time random access failure number and its always with Machine accesses the ratio between number；The second random access failure ratio are as follows: the second class user equipment is within the first specified time Random access failure number is compared with the ratio between its total random access number.

First ratio and second ratio can be preset ratio, first ratio in the present embodiment It can be equal with second ratio or differs.

When first ratio and equal the second ratio, that is, indicate to connect when the first access failure number with described second When entering unsuccessfully several ratio greater than the first ratio, m-x grouping is selected；When the first access failure number and second access When the ratio of failure number is less than the first ratio, m+x grouping is selected；When the first access failure number and second access lose When losing several ratio equal to the first ratio, current grouping can be kept constant；It certainly in specific implementation, can also be when described When first access failure number and the second access failure number are equal to the first ratio, m-x grouping or m+x grouping are selected.

When first ratio and the second ratio difference, first ratio is greater than second ratio.Such as when first Ratio is equal to X；Second ratio is equal to Y；X>Y；X and Y is positive number.When the first access failure number and the second access failure number Ratio be greater than X when, select m-x grouping.When the ratio of the first access failure number and the second access failure number is less than in Y When, select m+x grouping.When the ratio of the first access failure number and the second access failure number is greater than in Y and when being less than X, Current group can be kept constant.

In the specific adjustment, it if presently described m is equal to 1, indicates currently to be grouped for the 1st kind, even if first access The ratio of failure number and the second access failure number is greater than the first ratio, and reselection m-x grouping of also having no idea at this time may be used To keep current group constant, i.e., m is still selected to be grouped.If presently described m is equal to N, even if toilet states the first access failure Less than the second ratio, selection m+x grouping of also having no idea can also be protected several and the second access failure number ratio at this time It is constant to hold current group, i.e., m is still selected to be grouped.

In summary, the present embodiment is based on any of the above-described embodiment and provides how one kind specifically adjusts the first random access money The method for the random access resource number for including in source group and the second random access resource group has the advantages that realize easy.

It is specific as executed by the period in addition, information processing method described in the present embodiment can be carried out with iterative cycles, such as with First specified time was a time quantum, and each time quantum carries out the primary adjustment.Assuming that N=8, i.e. expression base station is real 8 groupings are now formd, the system of the first random access information and the second random access information is all carried out in each time quantum Meter and record carry out dynamic adjustment according to record result, and by the first random access parameter adjusted and the second random access Parameter is issued to different types of user equipment, returns to circulation dynamic in this way and adjusts, it is ensured that first kind user equipment and the Two class user equipmenies energy access base station can simultaneously be interacted with base station progress effective information.
