Specific embodiment
It will be appreciated by those skilled in the art that as described in the background art, when user equipment be based on the prior art and network start with
Machine accesses (Random Access, abbreviation RA), when with to the network request ascending resource, even if the user equipment requests
With highest priority (or the user equipment has highest access priority), the user sets the upstream data of transmission
Standby ascending resource request may still be refused by network.Wherein, the ascending resource request, which can be carried on, is sent to network
In random access lead code.For example, all ascending resources of the network are each assigned to other earlier than the user equipment
Send the user equipment of random access lead code；Although alternatively, the random access lead code of the user equipment is multiple with other
The random access lead code of user equipment is sent to the network simultaneously, but network fails reception or decoding has compared with Gao You
The corresponding ascending resource request of the upstream data of first grade.Sometimes, the random access of the user equipment with highest priority
Lead code may reach network side after the random access lead code of the lower user equipment of other priority, at this point, preferentially
The higher data of grade instead can be just processed after the lower data of priority, for example, the user with higher priority sets
Standby upstream data request can be just processed after the upstream data request of the user equipment with more low priority.
Inventor the analysis found that, this is because it is existing establish random access during, user equipment can not
The priority for indicating the upstream data that its this request of network uploads, also results in network that can not receive random access preamble
The priority that user equipment requests the upstream data sent is understood when code, so that network is not known how more rationally, efficiently
Distribute its ascending resource.
In order to solve this technical problem, in user equipment side, user equipment according to the priority of upstream data determine with
Machine access lead code, the random access lead code are selected from candidate random access preamble set；It is sent to network described random
Access lead code, the random access lead code are at least used to request to send the upstream data.It will be appreciated by those skilled in the art that
Technical solution based on the embodiment of the present invention, user equipment can indicate that it is asked to network in the random access lead code of transmission
The priority of the upstream data of transmission is sought, to enable the network to judge whether according to the priority of the upstream data to give the use
Family equipment uplink authorization.
Further, in network side, network receives the random access lead code that user equipment is sent, the random access preamble
For code at least for requesting to send upstream data, the random access lead code is selected from candidate random access preamble set；According to
The random access lead code determines the priority of the upstream data；According to the priority of the upstream data to the user
Equipment sends feedback information, to allow or refuse the request of the random access lead code.It will be appreciated by those skilled in the art that this hair
The technical solution of bright embodiment can ensure that there is the higher ascending resource request of priority higher probability to obtain uplink authorization,
To more reasonably optimize the random access process for ascending resource request.
It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, with reference to the accompanying drawing to this
The specific embodiment of invention is described in detail.
Fig. 1 is a kind of flow chart of accidental access method of the first embodiment of the present invention.Wherein, by being established with network
Random access, user equipment (User Equipment, abbreviation UE) can send random access lead code to the network, to ask
It asks to the network and sends upstream data；The present embodiment can be the specific stream that the random access is described from user equipment side
Journey.
Specifically, in the present embodiment, the accidental access method may include steps of:
Step S101 determines random access lead code, the random access lead code choosing according to the priority of upstream data
From candidate random access preamble set.
Step S102 sends the random access lead code to network, and the random access lead code is at least used to request
Send the upstream data.
More specifically, the candidate random access preamble set may include multiple random access lead codes.It is preferred that
Ground, candidate's random access preamble set can be one section of continuous preamble sequence (alternatively referred to as bit sequence).
Further, the user equipment can by the random access lead code to network request ascending resource, with
The upstream data is sent to network based on the ascending resource.
Further, user equipment can request network reserving resources by random access lead code, for passing through in the future
The resource sends scheduling request (Scheduling Request, abbreviation SR) to network, meanwhile, the user equipment can also lead to
It crosses the random access lead code request and data is sent to network by random access process (procedure).
Further, in response to the random access lead code, the network can choose to be awarded in random access response
The upstream request of power or refusal user equipment can more indicate whether it is user equipment future in the random access response
The SR that may be sent retains resource.Wherein, the resource can be one group of resource.
Further, the multiple random access lead code can correspond respectively to the upper line number with different priorities
According to.For example, the higher and lower upstream data of priority can correspond respectively to difference in the candidate random access lead code
Random access lead code.Wherein, about the judgment criteria of the height of the priority can by those skilled in the art according to
Actual needs determines.
Further, the priority of the upstream data can be based on the excellent of the affiliated channel of the upstream data or channel group
First grade；Request sends the priority of the user equipment of the upstream data；And/or the type of service of the upstream data
(traffic type) is determined.Alternatively, the priority of the upstream data can also be based on the user equipment (or the use
Family device request transmission upstream data) service type determine.
Further, the channel group can be used for transmitting upstream data and/or signaling, wherein the channel group can be with
Including at least one channel.For example, (4 channel groups are at most configured with) when the quantity of the channel group is not more than four,
The channel group can be logic channel group (Logical Channel Group, abbreviation LCG), and be contained in the logic letter
The channel of road group can be logic channel (Logical Channel, abbreviation LC).In another example when the quantity of the channel group is big
When four, the channel group (can be able to be channel group as defined in existing protocol, also not for other kinds of channel group
Exclude channel group as defined in future protocol), and the channel for being contained in same channel group can have identical attribute, it is such as preferential
Grade, Packet Delay Budget (packet delay budget), packet loss (packet error loss rate) etc..It is excellent at one
It selects in example, different random access lead codes can correspond to different priorities in candidate's random access preamble set
Channel or channel group.
Further, the step S101 may include step: according to the affiliated channel of the upstream data or channel group
Priority selects corresponding random access lead code from the candidate random access preamble set.
It is possible to further be indicated on described by Backoff instructions field associated with the random access lead code
The priority of row data.
As a non-limiting embodiment, the Backoff instructions field can be carried on the random access lead code.
For example, the Backoff instructions field carried in the random access lead code is bigger, corresponding to the random access lead code
The channel priority it is lower, corresponding request is lower by the priority for the upstream data that the channel is sent.Ability
Field technique personnel understand that different random access lead codes can correspond to different bit sequences, set when network receives user
When the random access lead code that preparation is sent, the network can determine the user according to the bit sequence of the random access lead code
Channel (or channel group) belonging to the upstream data that this request of equipment is sent, so it is excellent based on the channel (or channel group)
First grade determines the priority of the upstream data.
As another non-limiting embodiment, the Backoff instructions field can be in the random access lead code
Implicitly (implicitly) is indicated.For example, the prefixed time interval by keeping for Backoff instructions field, the random access
The bit sequence of lead code can serve to indicate that the length of the Backoff instructions field.
Alternatively, the resource for sending the random access lead code can serve to indicate that user equipment needs to be implemented how many
Backoff, wherein the resource may include the resource in time domain and frequency domain.For example, if preamble sequence X (connects at random
Enter the bit sequence X of lead code) it is to be sent by time-domain resource t1, then the preamble sequence X can correspond to Backoff and refer to
Show domain t1；If the preamble sequence X is sent by time-domain resource t2, the preamble sequence X be can correspond to
Backoff instructions field t2.It will be appreciated by those skilled in the art that by the priority for defining resource, the network can notify user
The priority for the data that equipment is sent according to its needs selects corresponding resource to send the random access lead code.
Further, priority is higher, and corresponding Backoff instructions field can be shorter, correspondingly, having higher priority
User equipment can choose and be associated with the random access lead code of shorter Backoff instructions field and be sent to the network.
Preferably, the corresponding relationship of the Backoff instructions field and the priority of the upstream data can be carried on institute
The system information for stating network transmission, alternatively, user equipment side can also be programmed in advance by hard coded.Wherein, the system
Information may include minimum system information (Minimum System Information, abbreviation MSI), and those skilled in the art are also
It can according to need and the corresponding relationship is carried by other systems information.
Further, if logic channel group or other channel (such as logics for including by the channel group of channel group creating
Channel) with equal priority (such as the data priority having the same transmitted on these channels), then these channel groups
It can correspond to identical random access lead code.
Alternatively, when multiple channels that channel group includes have different priorities when, can also be by multiple random access before
Leading code respectively corresponds the channel in the channel group with different priorities.
Further, the user that the candidate random access preamble set can send the upstream data with request sets
Standby device type is corresponding, such as based on cellular narrowband Internet of Things (Narrow Band Internet of Things, abbreviation
NB-IoT).For example, network can preset different candidate random access lead code collection for the user equipment of distinct device type
It closes, when the user equipment is needed by sending random access lead code to request multi-upstream access, the user equipment can be with
It receives the system information of Web broadcast and therefrom obtains the candidate random access lead code for corresponding to equipment of itself type, Jin Ercong
Before choosing the random access for the priority for corresponding to the upstream data that this needs uploads in candidate's random access lead code
Leading code.
As a non-limiting embodiment, sensor (sensor) and mobile phone can correspond to different device types,
And then correspond to different candidate random access preamble sets, to obtain better efficiency.For example, corresponding to the time of sensor
It selects the possibility numerical value of the Backoff instructions field of random access lead code in random access preamble set that can be less than and corresponds to hand
The correspondence numerical value of the Backoff instructions field of random access lead code in the candidate random access preamble set of machine, so that mobile phone
Sensor can be lagged behind by the dispatching uplink resource request that random access is sent to be authorized, to ensure that sensor can be preferential
Data are uploaded, and allow sensor to obtain longer dormancy time, and channel can be immediately accessed upon wake-up.Alternatively, not
With the specific value of Backoff instructions field of the candidate random access preamble set random access lead code that includes can also be with
Partly or entirely overlapping, so that the user equipment of distinct device type can obtain balanced authorization probability.
Further, the priority of the upstream data and the robustness of the random access lead code are proportional.For example,
For the upstream data with higher priority, it is corresponding the upstream data can be improved by way of increasing cyclic prefix
The robustness of random access lead code, so that the random access lead code described in noise circumstance remains to be properly received by network
And parsing.In another example can also by way of increasing the sequence repetition number of the random access lead code, improve it is described with
The robustness of machine access lead code, it will be appreciated by those skilled in the art that other can be improved the robust of the random access lead code
The mode of property is equally applicable to the technical solution of the embodiment of the present invention, and it will not be described here.
It, can be in the poor application scenarios of the signal transmission qualities such as noise circumstance as a non-limiting embodiment
Suitably increase the robustness of corresponding random access lead code according to the priority of the upstream data, described is connect at random with improving
Enter the probability that lead code is properly received and is correctly decoded and (alternatively referred to as parse) by network, so that it is guaranteed that with before the random access
The authorized rate of the corresponding ascending resource request (alternatively referred to as uplink access request) of leading code.
Further, accidental access method described in the present embodiment can be comprising steps of receive the feedback letter of the network
Breath；In response to the feedback information, Xiang Suoshu network sends or does not send the upstream data.For example, working as the feedback information
It, can be based on the uplink of network distribution when receiving information (alternatively referred to as ascending resource request receives information) for uplink access request
Resource sends the upstream data, and the ascending resource is carried on the feedback information.In another example when the feedback information is upper
Row access request refusal information (or other are used to indicate the upper line number that network does not have resource to can satisfy user equipment requests upload
According to priority information, alternatively referred to as ascending resource request refusal information) when, the user equipment can not be sent on described
Row data.
Further, the uplink access request can be sent while sending random access lead code or later.Example
Such as, can be carried in the random access lead code be used to indicate user equipment will in later send uplink access request instruction
Information, after the network receives the random access lead code, the user equipment the instruction information instruction time to
The network sends the uplink access request.
By upper, using the scheme of first embodiment, user equipment can indicate network by the random access lead code
The type of service (or service type) for sending the user equipment of the ascending resource request, so that the user with higher priority
The ascending resource request of equipment can have higher authorization probability.
