Description
Technical field
This application involves fields of communication technology, more particularly, to a kind of sending method of clustering paging message.
Background technique
Group system has strict requirements to call set-up time, and usual group is exhaled settling time to be no more than 300ms, individual calling
Settling time is no more than 500ms.Call establishment include Signalling exchange, media parameter negotiate, carrying establish and etc., if
Called terminal is in Idle state, it is also necessary to page to it.And the paging mechanism of standard LTE, the smallest paging cycle also need
32 radio frames are wanted, i.e. 320ms is unable to satisfy the requirement of group system fast call establishment.In order to accelerate the hair of paging message
Chance is sent, allows cluster user by Quick Paging, is commonly designed clustered paging control channel (TPCCH) bearing cluster paging letter
Breath, the period that TPCCH is sent can be configured to several lesser radio frames of numerical value, in calling time (defined PF and PO subframe)
After arrival, pass through TPCCH channel signalling of bouquet paging message.For group-calling service, called terminal can remain idle after being paged
State is answered group and is exhaled；For single call service, pages called terminal and make it into connected state, restore eat dishes without rice or wine connection and signaling connection.
Existing clustered paging mainly includes that group exhales paging, individual calling paging quickly to carry out call setup.Exhale one of group
Key property is the entrance that lags, and can answer in time group with the user being added after guarantee and exhale, therefore group exhales paging information not only to wrap
It includes group and exhales paging when establishing, further include that group exhales lasting period periodically to lag into paging, and group exhales paging when establishing
Being divided into group exhales the group initially set up under the scenes such as paging and mobile management that enlarging is exhaled to page.
For dynamic reorganization, it is distant it is dizzy it is/distant to get killed/bring back to life, supplementary services, the group system such as real-time short data also require quickly finger
Order issues so that business comes into force as early as possible.The paging of the point-to-point supplementary service associated terminal of IDLE state is usually passed through in existing system
Period, longer LTE PCCH channel issued, in order to accelerate issuing for cluster instruction, can also on TPCCH channel bearing point pair
Point supplementary service needs to solve at this time the Trigger Problems of various cluster service paging information to the paging information of terminal.
In addition, interface-free resources are limited to, the group paging or point-to-point paging acknowledgment carried in a clustering paging message
Quantity is conditional.When calling time arrives, foundation (enlarging) paging, point-to-point benefit are exhaled in the individual calling paging at the moment, group
Service paging is filled, is lagged in addition the group that may be triggered is exhaled into paging, paging acknowledgment quantity is likely to will exceed TPCCH channel
The capacity of upper single paging message leads to paging cycle hereafter, will also continue the related paging for sending previous moment, at this
It under kind scene, needs to consider the dispatching method that network side MAC layer sends paging message, is guaranteed according to group service characteristic all kinds of
The orderly transmission of service paging information to meet requirement of the group system to performances such as call set-up times, and accelerates instruction
It issues and comes into force.
Existing scheme is general, and only carrying group exhales paging and individual calling paging information on TPCCH channel, and when transmission, which is not distinguished, seeks
Type is exhaled, is scheduled using first in first out or the method sorted by priority, if only suitable according to the transmission of first in first out
Sequence may result in higher newly-built group of service priority when paging capacity has been expired and paging acknowledgment exhaled to be delayed by transmission, can not
Meet the requirement of call set-up time；If only sorted by priority, because group calling priority is usually above individual calling, when an individual calling
When paging is triggered, it may come to lag and exhale paging to be delayed by transmission below into group, and the point-to-point supplementary service of cluster is not
Have call priority information, also has no idea to carry out priority ranking.
In order to solve the problems, such as that paging acknowledgment congestion, the prior art propose multiple calling times in a paging cycle
Send the scheme of paging message.Specifically, the first calling time of the configuration information instruction paging cycle of TPCCH channel, such as
The fruit moment, there are not sent paging acknowledgments, and the next calling time in this period is indicated in paging message.The program is not
The trigger condition for specifying all kinds of paging informations, its essence is the sending cycles for shortening clustering paging message, increase the power consumption of UE
Amount, it is larger to the change of existing clustered paging mechanism, it cannot guarantee that the orderly of all kinds of paging informations when paging capacity has been expired
It sends.
Therefore, the orderly transmission of all kinds of service paging information is not can guarantee when paging capacity has been expired in the prior art.

Therefore the orderly transmission that can guarantee all kinds of service paging information meets the requirement of group system fast call establishment, and quickly
Under send instructions.
It is the sending method flow diagram of clustering paging message referring to attached drawing 1, specifically includes the following steps:
101, eNB distinguishes different business according to instruction, and the corresponding clustered paging of triggering generation, which records and is stored in first, to be sought
Exhale queue or the second page queue.
Different business is distinguished in the instruction or own local instruction that eNB is sent according to core net.The finger that core net is sent
Show the message such as foundation/modification of paging message and group service including point-to-point service.
Point-to-point service includes the following three types situation to the triggering of the paging acknowledgment of terminal:
Paging for group service to UE, the S1 interface Paging message that extended core net is sent to eNB carry calling
Precedence information.Retain a segment limit in existing call priority value, for dynamic reorganization, distant dizzy, distant get killed, brings back to life
Do not have the point-to-point cluster supplementary service of call priority, the call priority value retained for its distribution.
(1) if indicating point-to-point industry without carrying call priority information in the Paging message that core net is sent
The paging type of business is the paging of LTE public network, and eNB will be issued after the arrival of LTE paging cycle by LTE PCCH channel point-to-point
The paging information of business.
(2) if carrying call priority information in the Paging message that core net is sent, and the value of call priority is not
Belong to reserved-range, indicates that the paging type of point-to-point service is individual calling called paging, it is called that triggering eNB generates corresponding individual calling
Paging acknowledgment is simultaneously deposited into the first page queue, is issued after the clustered paging moment reaches by TPCCH channel.
(3) if carrying call priority information, and the value category of call priority in the Paging message that core net is sent
In reserved-range, the paging type of point-to-point service is indicated as point-to-point cluster supplementary service paging, triggering eNB generates corresponding
Point-to-point cluster supplementary service paging acknowledgment is simultaneously deposited into the second page queue, passes through after the clustered paging moment reaches
TPCCH channel issues.
The triggering of the paging acknowledgment of group service includes but is not limited to following four situation:
The paging information of group service mainly includes that group exhales foundation paging, group to exhale enlarging paging, group that modification paging, group is exhaled to exhale
It lags into paging and the paging of multicast short data.
For the group system of fixed group call region, there is no groups, and enlarging to be exhaled to page.But if the area Zu Hu of group system
Domain is dynamically determined according to group member's distribution situation, then because the movement of group member will likely trigger in group-calling process
It is original that there is no the region enlarging groups that group is exhaled to exhale, for eNB, group exhale enlarging operate and group exhale establish it is identical.
(1) if the group that eNB receives core net transmission exhales foundation to indicate, including initial group exhales and establishes scene or group is exhaled
Enlarging scene is exhaled for the group of the eNB in the process, triggering generation group exhales foundation (enlarging) to indicate corresponding group and exhales foundation (enlarging)
Paging acknowledgment is simultaneously stored in the first page queue.
(2) if the group that eNB receives core net transmission exhales modification to indicate, including modifying the context ginseng that group has been established and exhales
Number, certain cell has been established group and exhales and the scenes such as exhales in other cell enlarging groups under scene at this eNB, and triggering generation group exhales modification to refer to
Show that corresponding group is exhaled modification paging acknowledgment and be stored in the first page queue.
(3) it lags if the group that eNB receives core net transmission is exhaled into instruction (core net maintenance lagged into the period),
Or eNB arrival lags into period (eNB maintenance lagged into the period), is specifically determined using which kind of mode by system realization,
Triggering generates corresponding clustered paging and is recorded as group and exhales to lag into paging acknowledgment, and group is exhaled and is lagged into paging acknowledgment deposit the
Two page queues.
(4) if eNB receives the multicast short data instruction of core net transmission, and the group does not carry out group currently and exhales, and will touch
Multicast short data occurs into indicate corresponding multicast short data paging acknowledgment and be stored in the first page queue.
Paging according to above-mentioned point-to-point service to the three kinds of situations and group service of the paging acknowledgment triggering of terminal to group
Record four kinds of situations of triggering.It is found that including: that individual calling called paging records, group exhales foundation (enlarging) to seek in the first page queue
Record, group is exhaled to exhale modification paging acknowledgment and multicast short data paging acknowledgment.It include: point-to-point cluster supplement in second page queue
Service paging record and group are exhaled and are lagged into paging acknowledgment.
Referring to table first is that the first page queue schematic diagram；Table is second is that the second page queue schematic diagram.
Table one
Table two
Industry is supplemented to the paging acknowledgment of terminal, including individual calling called paging and point-to-point cluster for point-to-point related service
Business is paged, and terminal feature parameter such as international mobile subscriber identity (IMSI), call priority are included at least in paging acknowledgment；
Paging acknowledgment relevant for group service, including group exhale foundation (enlarging) paging, group that modification paging, group is exhaled to exhale late
Enter paging and the paging of multicast short data afterwards, group number, call priority, group wireless network are included at least in paging acknowledgment and is temporarily marked
Know (group RNTI).
102, after the arrival of clustered paging moment, paging note first is extracted according to the sequence of first in first out in the first page queue
Then record extracts paging acknowledgment according to the sequence of first in first out in the second page queue, constructs clustered paging by paging acknowledgment
Message, and pass through TPCCH channel signalling of bouquet paging message.
First page queue storage individual calling called paging record, group exhale foundation (enlarging) paging acknowledgment, group that modification is exhaled to page
Record and multicast short data paging acknowledgment etc..The priority of first page queue is higher than the second page queue, and inner queue is sought
Record is exhaled to be scheduled with the sequence of first in first out.
Call setup (including individual calling and group are exhaled) and the operation of multicast short data are initiated by user, and the operating time is usually with the second
Grade is unit.Group exhales enlarging that may only trigger when UE is moved to new cell.It can consider a calling time signalling of bouquet
Undrawn paging acknowledgment is not present after paging message in first page queue, it is ensured that fast call establishment.When the first paging team
After being classified as sky, then start to extract the paging acknowledgment in the second page queue with the sequence of first in first out.Point-to-point cluster supplements industry
The paging acknowledgment of business is also the component part of clustering paging message, is sent by period shorter TPCCH channel, accelerates instruction
It issues and comes into force.
After reaching at the clustered paging moment, clustered paging is constructed according to the paging acknowledgment that above-mentioned sequence extracts page queue
It is sent after message.If the capacity of the calling time paging acknowledgment has been expired, remaining paging acknowledgment will be deferred to next paging
Moment continues to send.
It should be understood that include in the page queue quantity and individual queue of eNB maintenance is all kinds of in the embodiment of the present invention
Paging acknowledgment can be extended adjustment according to actual requirement.Its principle is that paging list embodies group service characteristic, selection
By group service to the requirement of time depending on.Low priority column are extracted after the paging acknowledgment in high priority list has extracted
Paging acknowledgment in table, according to the sequential build clustering paging message of first in first out inside list.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in protection of the invention
