To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention Specific embodiment be described in detail.
Fig. 1 is a kind of flow chart of paging method of the embodiment of the present invention.
Paging method shown in FIG. 1 can be used for base station side, and the paging method may comprise steps of:
Step S101: resource indication information used in the random access to user equipment RP Radio Paging instruction triggering, it is described Resource indication information indicates dedicated preamble and the PRACH resource that each wave beam is specified；
Step S102: in each calling time of paging cycle, to the user equipment hair in leisure state or inactive state Paging indication information is sent, the paging indication information indicates that the paging state of user in each paging group, the paging state are It is paged or is not paged；
Step S103: receiving the dedicated preamble that the first user equipment in the paging group being paged is sent, and described first User equipment sends the dedicated preamble using the PRACH resource that its resident wave beam is specified；
Step S104: it is corresponding that the PRACH resource that the dedicated preamble uses is sent using first user equipment Wave beam sends the customer equipment identification being paged to first user equipment, to judge whether to continue for the first user equipment Execute random access.
In specific implementation, in step s101, base station can by resource indication information to user equipment indicate it is dedicated before Leading code and the corresponding Physical Random Access Channel of each wave beam (Physical Random Access Channel, PRACH) money Source.Wherein, each dedicated preamble can be used by multiple user equipmenies (User Equipment, UE)；Wave beam and PRACH Resource corresponds.For example, wave beam 1 is corresponding with PRACH1, wave beam 2 is corresponding with PRACH2, and wave beam 3 is opposite with PRACH3 It answers.
In the present embodiment, the dedicated preamble is exclusively used in the random access procedure of paging instruction triggering.
Furthermore, the dedicated preamble may include with the one-to-one lead code of each paging group, or with it is every What a one-to-one lead code of wave beam or all paging groups of all wave beams were used in conjunction with is exclusively used in the random of paging instruction triggering The corresponding lead code of access procedure.
Specifically, base station can send the resource indication information by system information, then UE is believed by decoding system Breath can obtain the resource indication information.The PRACH resource can send dedicated preamble for UE, and PRACH resource can be with It is the time-frequency location of resource.Closer, since the size of PRACH resource is fixed, such as 6 Physical Resource Block (Physical Resource Block, PRB), therefore the PRACH resource can be the initial position of time domain and rising for frequency domain Beginning position；It is also possible to the index of PRB.
In specific implementation, there are multiple calling times in each paging cycle, then in step s 102, base station is sought each The moment is exhaled, paging indication information is sent to the user equipment in leisure state or inactive state, to indicate to use in each paging group The paging state at family.Wherein, the paging state of user can indicate in the paging group with the presence or absence of user equipment quilt in paging group Paging.
Specifically, can indicate the paging state in paging group by bit map (bitmap) mode, 0 is represented accordingly Paging group is paged, and 1, which represents corresponding paging group, is not paged；It is also possible to the corresponding paging group of 1 representative to be paged, 0 represents accordingly Paging group is not paged.
User equipment after receiving paging indication information, it can be determined according to paging indication information belonging to paging group Whether it is paged.If the paging group where user equipment is paged, which needs to send Special leader to base station Code；If the paging group where user equipment is not paged, which does not need to send dedicated preamble to base station.Into One step, the specified PRACH resource of its resident wave beam can be used in user equipment.And then in step s 103, base station can be with Receive the dedicated preamble that the first user equipment in the paging group being paged is sent.
It is understood that the first user equipment in the embodiment of the present invention refers to the use belonged in the paging group being paged Family equipment.
It will be apparent to a skilled person that the first user equipment can be with to the process that base station sends dedicated preamble It is the process for initiating random access.
And then in step S104, the PRACH that the dedicated preamble uses is sent using first user equipment and is provided The corresponding wave beam in source sends the customer equipment identification being paged to first user equipment, to be used for first user equipment Judge whether to continue random access.That is, the wave beam that reception dedicated preamble can be used in base station is sought to send The customer equipment identification exhaled.
Then first user equipment, can be by the user equipment of itself after receiving the customer equipment identification being paged It identifies and is compared with the customer equipment identification being paged, if unanimously, continuing random access to base station, otherwise need not Continue random access.
In the present embodiment, user equipment can be used the specified dedicated preamble in base station and initiate random access request, base station According to the dedicated preamble or Physical Random Access Channel (Physical Random Access Channel, PRACH) received Resource, which determines to send, requests corresponding downlink wave beam, is then paged on the wave beam by accidental access response message instruction User list.For the customer equipment identification indicated in the customer equipment identification of itself and access response message to be checked, If customer equipment identification matches, the success of this user equipment is paged, which continues random access procedure；If Customer equipment identification mismatches, then pages the failure of this user equipment, which terminates access procedure.
It should be noted that the customer equipment identification can be service Temporary Mobile Subscriber Identity (Serving Temporary Mobile Subscriber Identity, S-TMSI) or international mobile subscriber identity (International Mobile Subscriber Identity, IMSI), the embodiment of the present invention is without limitation.
The embodiment of the present invention indicates that letter indicates that paging instruction triggers each wave beam and carries out what random access was specified by resource PRACH resource, for the first user equipment resided on same wave beam can be used identical PRACH resource send it is described specially With lead code, hence for the first user equipment for using identical PRACH resource, base station only needs to send the use being once paged Family device identification avoids base station and sends the customer equipment identification being repeatedly paged on same wave beam, and then saved downlink Resource.
Furthermore, base station can carry the customer equipment identification being paged in access response message, and one is concurrent Give the first user equipment.The embodiment of the present invention can be avoided by the specified PRACH resource used for paging reported based on wave beam Base station repeatedly sends the access response message including Called Subscriber identification information on same wave beam, reduces opening for downlink resource Pin.
Preferably, the dedicated preamble and paging group correspond, and step S103 may comprise steps of: receiving institute State the dedicated preamble corresponding with paging group belonging to first user equipment of the first user equipment transmission.
In the present embodiment, dedicated preamble and paging group are corresponded, for example, paging group PG1 corresponds to dedicated preamble P1, Paging group PG2 corresponds to dedicated preamble P2, and paging group PG3 corresponds to dedicated preamble P3.First user equipment can be according to its institute The paging group of category determines its used dedicated preamble, and is sent and determined using the PRACH resource that its resident wave beam is specified Dedicated preamble.Then base station is received and paging belonging to first user equipment using the wave beam that the first user equipment is resident The corresponding dedicated preamble of group.
Further, step S104 may comprise steps of: the Special leader sent according to first user equipment Code determines paging group belonging to first user equipment；The dedicated preamble is sent using first user equipment to use The corresponding wave beam of PRACH resource send in paging group belonging to first user equipment and sought to first user equipment The customer equipment identification exhaled.
In the present embodiment, then base station is when sending the customer equipment identification being paged, in order to avoid repeating to send, under saving Row resource first can determine corresponding paging group according to the dedicated preamble that the first user equipment is sent, then set to the first user Preparation gives the customer equipment identification being paged in the paging group belonging to it.User equipment due to residing in same wave beam uses phase Same PRACH resource, and the user equipment for belonging to same paging group uses identical dedicated preamble, then on same wave beam User equipment in same paging group, base station only needs to send the customer equipment identification being once paged, to save downlink money Source.
In a concrete application scene of the invention, base station indicates each paging group PG by system informationkIt is corresponding it is dedicated before Leading code is Preamblek, k=1~8；Each wave beam BeamnSpecified is used to page the PRACH resource for accessing and using as PRACHn, n =1~4.In calling time PO3, network passes through user equipment in each paging group on wave beam sweep method transmission calling time PO3 Paging state, paging indication information 01010001, i.e. paging group PG1, PG5, PG7Inside there is user equipment to be paged.Wherein, UE1 belongs to paging group PG1, UE2 belongs to paging group PG5, UE3 belongs to paging group PG5, UE4 belongs to paging group PG8.Therefore, UE1, UE2, UE3 need to carry out random access procedure.
Wherein, UE1 is resided on wave beam 1, therefore the PRACH resource PRACH that UE1 is specified in wave beam 11Upper transmission Special leader Code Preamble1To base station；
