In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 is the flow chart for the accidental access method competition-based that one embodiment of the invention provides.As shown in Figure 1, this The method of embodiment includes:
Main UE in step 101, user group sends 2/ layer 3 of layer to network side equipment in group random access time window and disappears Breath, 2/ layer of 3 message of the layer include transmission demand instruction information, and the transmission demand instruction information is for obtaining network side equipment Know the information for having the UE of transmission demand in user group.
Wherein, the auxiliary UE in main UE and user group uses identical random access resource, and auxiliary UE is in group random access Between do not send sequence code to network side equipment in window, the random access resource include main UE in group random access time window The sequence code sent on running time-frequency resource to network side equipment and the running time-frequency resource used.
Step 102, main UE are received after network side equipment receives 2/ layer of 3 message of layer in group random access time window and are returned Notice message is completed in the access returned, to complete random access procedure.
Illustrating herein first, the network side equipment in the present embodiment and the subsequent each embodiment of the present invention can be base station, But not limited to this, it can also be other any equipment that the function of network side equipment in the embodiment of the present invention may be implemented.
In the present embodiment, UE is grouped to form user group, each user group includes two or more UE. User group can be preset, and the UE that preferably can choose same type constitutes same user group.For example, can choose has The UE of identical services type has the UE of same time lead (Timing Advance, referred to as TA) as same use Family group.Wherein, the scale of each user group and size without limitation, can be depending on practical applications.
In each user group, a UE is pre-selected as main UE, other UE and is referred to as auxiliary UE.In the present embodiment, A group random access is carried out as unit of user group.Main UE in each user group represents the user group initiation group random access mistake Journey, i.e., main UE are responsible for sending sequence code (preamble) and 2/ layer of 3 message of layer to network side equipment, and auxiliary UE is in group random access Between do not send sequence code to network side equipment in window.Master is known in advance in member (including auxiliary UE and main UE) in each user group The ID of UE and the identification information of user group.Optionally, the identification information of user group can be the ID of main UE in the user group, use The sequence code etc. that the ID of family group or the user group use, but not limited to this.
In the present embodiment, a group random access time window is defined for each user group, each user group is in its correspondence Group random access time window in, You Qizhu UE is to network side equipment initiation group random access.Group random access time window is practical On be a time range, such as can be from 1 point to 1 points 2 minutes, from 2 points 10 seconds etc. 22 minutes 30 seconds 20 minutes to 2 points.For with Main UE and auxiliary UE in the group of family use identical group of random access time window.
Before carrying out group random access, main UE or auxiliary UE can obtain the group random access time window used.Optionally, it uses Family group and network side equipment can make an appointment the group random access time window used, then the main UE in user group and auxiliary UE can be pre- First store the group random access time window of agreement.Based on this, auxiliary UE and main UE directly locally can obtain the group made an appointment Random access time window.Optionally, network side equipment can send the user group institute by the main UE into user group and auxiliary UE in real time The instruction information of the group random access time window used.Based on this, before step 101, main UE can receive network side equipment hair The instruction information of the group random access time window sent.In addition, when auxiliary UE can also receive the group random access of network side equipment transmission Between window instruction information.The instruction information for the group random access time window that main UE and auxiliary UE is sent according to network side equipment, knows The group random access time window that should be used.
For different user groups, a group random access procedure is identical, therefore the present embodiment is with one of user group For be illustrated.Specifically, the main UE of the user group can be used when group random access time window is opened in the user group The sequence code that the user group uses, initiation group random access procedure are sent to network side equipment on running time-frequency resource.Due to user group Interior all members share identical sequence code and running time-frequency resource, therefore all members can know that identical RAR disappears in user group Breath, which includes the information such as TC-RNTI, TA order (Command).Main UE in user group can be in group random access Between the RAR that network side equipment is sent is monitored in window, and receive network side equipment and receive the use returned after above-mentioned sequence code The corresponding RAR of family group；Meanwhile the auxiliary UE in user group can also receive network side equipment transmission in group random access time window RAR。
For main UE, if main UE is not properly received network side equipment return in RAR receiving time window RAR sends sequence code to network side equipment again after can keeping out of the way a period of time；If main UE is in group random access time window Be not properly received the RAR of network side equipment return, then it can be after group random access time window individually to network side Equipment initiates random access.Here RAR receiving time window and group random access time window is different concept, when RAR is received Between window be less than group a random access time window.If main UE is successfully received network side equipment return in group random access time window RAR, then uplink sending time is adjusted according to the TA order in the RAR that receives, and to network side on above-mentioned running time-frequency resource Equipment sends 2/ layer of 3 message of layer, and 2/ layer of 3 message of the layer includes transmission demand instruction information, for making network side equipment know this There is the information of the UE of transmission demand in user group.It follows that the transmission demand instruction information of the present embodiment is wanted to indicate to use There is the UE of transmission demand in the group of family, can be any information for meeting the requirement.Network side equipment receives 2/ layer of 3 message of layer Afterwards, it can therefrom obtain transmission demand and indicate information, and indicate that information is directed to the random access of the user group according to the transmission demand Process carries out respective handling, and then the user group returns to access and completes notice message, so that main UE and auxiliary UE in the user group Know that group random access procedure is completed.
For auxiliary UE, if auxiliary UE is successfully received network side equipment return in group random access time window RAR, then auxiliary UE can obtain TC-RNTI from the RAR received, and will continue to receive network in group random access time window Notice message is completed in the access that side apparatus is sent, after being successfully received access completion notice message, using TC-RNTI as user The C-RNTI of group, random access procedure of user group is completed where knowing it.If auxiliary UE in group random access time window not Be successfully received the RAR of network side equipment return, then it can be individually to network side equipment after group random access time window Initiate random access.
In the present embodiment, the main UE or auxiliary UE individually initiate random access to network side equipment and refer to main UE or auxiliary UE Random access procedure competition-based is initiated according to the prior art, this is repeated no more.
Before carrying out random access, auxiliary UE and main UE needs obtain the random access resource used in advance.Optionally, net Network side apparatus and user group are made an appointment the random access resource that the user group uses.Based on this, auxiliary UE and main UE can into Before row random access, the random access resource made an appointment is obtained.Optionally, group leader and auxiliary UE can also connect at random Before entering, the random access resource being used in conjunction with is calculated by public information.Here public information can be user group The information that all members in the user groups such as the ID of ID or main UE both know about.
In an optional embodiment, the transmission demand instruction information that main UE is sent to network side equipment includes the main place UE The mark of the quantity and user group of UE in user group.In the quantity and user group that transmission demand instruction information includes UE in user group Mark in the case where, need the cooperation of network side equipment to be just able to achieve transmission demand instruction information to having transmission in user group The instruction of the UE of demand.The present embodiment provides the processing modes of two kinds of network side equipments cooperation, but are not limited to both, both Processing mode difference is as follows:
The first processing mode of network side equipment includes: that network side equipment refers in the transmission demand for receiving main UE transmission After showing information, on the one hand can determine specifically which user group has transmission demand, another party's veil according to the mark of user group Network side apparatus distributes one section of transmission for the user group and requests resource, for supplying the user group according to the quantity of UE in the user group In there is the UE of transmission demand to send transfer request message, and then know the information for having the UE of transmission demand in the user group.Specifically , after network side equipment receives 2/ layer of 3 message of layer, it is directed to according to the quantity of UE in wherein user group and the mark of user group User group distribution transmission request resource, and contention resolution message is returned after receiving 2/ layer of 3 message of the layer, it is denoted as first Contention resolution message, first contention resolution message include the position instruction letter for the transmission request resource that network side equipment is distributed Breath.Here the position indication information of transmission request resource can be from three frequency resource, orthogonal code resource, time resource latitudes It is indicated.Later, network side equipment, which can also receive, has the UE of transmission demand to request resource according to the transmission in the user group The transfer request message that position indication information is sent on the corresponding position of transmission request resource.
The first processing mode based on above-mentioned network side equipment, for main UE, if main UE does not have transmission demand, Then main UE receives network side equipment after the first contention resolution message returned after receiving 2/ layer of 3 message of layer, do not need to Network side equipment sends transfer request message.If main UE has transmission demand, the implementation process of above-mentioned steps 102 includes: master UE receives the first contention resolved that network side equipment returns after receiving 2/ layer of 3 message of layer in group random access time window Message, first contention resolution message include the position indication information of transmission request resource；Main UE is according to from user group Location information and above-mentioned transmission request resource position indication information, in group random access time window transmission request resource Corresponding position on to network side equipment send transfer request message.In this embodiment, no matter main UE has transmission demand also It is no transmission demand, it is exactly network side equipment that notice message is completed in the access that main UE is received in group random access time window The first contention resolution message returned after receiving 2/ layer of 3 message of layer, first contention resolution message include transmission request The position indication information of resource.
The first processing mode based on above-mentioned network side equipment, for auxiliary UE, with main UE the case where is identical, here It wouldn't be described in detail, will be described in detail in subsequent embodiment.
Second of processing mode of network side equipment includes: that network side equipment refers in the transmission demand for receiving main UE transmission After showing information, on the one hand can determine specifically which user group has transmission demand, another party's veil according to the mark of user group Network side apparatus distributes one section of transmission for the user group and requests resource, for supplying the user group according to the quantity of UE in the user group In there is the UE of transmission demand to send transfer request message, and then know the information for having the UE of transmission demand in the user group.Specifically , after network side equipment receives 2/ layer of 3 message of layer, it is directed to according to the quantity of UE in wherein user group and the mark of user group User group distribution transmission request resource, and contention resolution message is returned after receiving 2/ layer of 3 message of the layer, it is denoted as first Contention resolution message, first contention resolution message include the position instruction letter for the transmission request resource that network side equipment is distributed Breath.Here the position indication information of transmission request resource can be from three frequency resource, orthogonal code resource, time resource latitudes It is indicated.Later, network side equipment, which can also receive, has the UE of transmission demand to request resource according to the transmission in the user group The transfer request message that position indication information is sent on the corresponding position of transmission request resource.Receiving transmission demand UE send transfer request message after, network side equipment can also return transmission request-reply message, with inform have transmission demand UE its successfully complete random access procedure.
Illustrate herein, the difference of second of the processing mode and the first processing mode of network side equipment is: network side After the transfer request message that the UE that equipment receives transmission demand is sent, transmission request-reply message can be returned.
Second of processing mode based on above-mentioned network side equipment, for main UE, if main UE does not have transmission demand, Then main UE receives network side equipment after the first contention resolution message returned after receiving 2/ layer of 3 message of layer, do not need to Network side equipment sends transfer request message, would not also receive the transmission request-reply message of network side equipment return.Cause This, in the case where main UE does not have transmission demand, the access that main UE is received in group random access time window completes notice and disappears Breath is exactly the first contention resolution message that network side equipment returns after receiving 2/ layer of 3 message of layer, first contention resolved Message includes the position indication information of transmission request resource.
If main UE has transmission demand, the implementation process of above-mentioned steps 102 includes: main UE in a group random access time window Interior the first contention resolution message for receiving network side equipment and being returned after receiving 2/ layer of 3 message of layer, first contention resolved Message includes the position indication information of transmission request resource；Main UE according to from user group location information and above-mentioned transmission The position indication information for requesting resource, to network side on the corresponding position of transmission request resource in group random access time window Equipment sends transfer request message；Main UE receives the transmission request-reply of network side equipment transmission in group random access time window Message, to complete random access procedure.Therefore, in the case where main UE has transmission demand, main UE is in a group random access time window It is exactly the transmission request-reply message that network side equipment returns that notice message is completed in the access inside received.
Further alternative, the transmission request-reply message that network side equipment returns includes the letter of the UE of transmission demand Breath.Network side equipment further indicates the information for having the UE of transmission demand by transmission demand request-reply message, is conducive to this There is the UE of transmission demand to determine a bit oneself to be successfully completed random access and can carry out data transmission.
Second of processing mode based on above-mentioned network side equipment, for auxiliary UE, with main UE the case where is identical, here It wouldn't be described in detail, will be described in detail in subsequent embodiment.
In the above-described embodiment, the transfer request message for thering is the UE of transmission demand to send to network side equipment can be but It is not limited to the active information of 1 symbol.
Either the first processing mode based on above-mentioned network side equipment is still based on based on above-mentioned network side equipment Second of processing mode, in the case where main UE has data transfer demands, when main UE is received in group random access time window Notice message is completed in the access that network side equipment is sent, and (for the first processing mode, access here completes notice message and is First contention resolution message；For second of processing mode, it is that transmission request-reply disappears that notice message is completed in access here Breath), after completing random access procedure, main UE can receive network side and set according to from the location information in user group The transfer resource that preparation is sent indicates information, and carries out data transmission on the transfer resource indicated by transfer resource instruction information.
Optionally, main UE carry out data transmission on transfer resource indicated by the above-mentioned transfer resource instruction information using Radio network temporary identifier can be public information or user group Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI) or It is to be determined according to default determining rule.Here public information refers to the information that all UE are known in advance in user group, such as The ID of user group, the ID of main UE, sequence code etc..
Further, above-mentioned default determining rule public information and the ID of main UE can be composed according to, or be root It is composed according to the ID of the C-RNTI and main UE of user group, but not limited to this.
