Group shown in Fig. 1 is exhaled in flow, during the clustered paging that base station is initiated to terminal, due to group membership's terminal
Need not be to any information of base station feedback, therefore whether base station can not be known in cell with the presence of group membership's terminal.For this purpose, this
Embodiment proposes a kind of clustered paging response method.
The present embodiment is by taking LTE broadband cluster systems as an example, as shown in Fig. 2, the clustered paging response of the present embodiment end side
Method includes：
Step 110, terminal receives the clustering paging message for the first group that base station is sent；
The identification information of the first group is carried in the clustering paging message for the first group that base station is sent.It needs to illustrate
It is that the clustering paging message of the first group can merge transmission with the clustering paging message of other groups, for example, when eventually
When cell where holding will be sent there are two the clustering paging message of the above group, base station can will merge the two or more group
Clustering paging message, send the clustering paging message after merging in predetermined paging time-slot, the cluster after the merging seeks
Message is exhaled to carry the identification information of the two or more group.
Step 120, the terminal determines the clustering paging message for responding first group；
Terminal determines that the condition for the clustering paging message for responding first group can have different settings.Show at one
In example, the terminal determines that this terminal is under the jurisdiction of first group, and when the terminal be in Idle state, determines described in responding
The clustering paging message of first group.In the example, terminal can search cluster in the identification information of oneself affiliated group and seek
The identification information for exhaling the first group carried in message illustrates that this terminal is under the jurisdiction of the first group if found.
In another example, the terminal determines that this terminal is under the jurisdiction of first group, and the clustering paging message is taken
Tape terminal needs the instruction information that responds, and when the terminal be in Idle state, determines that the cluster of response first group is sought
Exhale message.
In another example, the terminal determines that this terminal is under the jurisdiction of first group, and the clustering paging message is taken
Tape terminal needs the instruction information responded, and the terminal is in connected state, and the priority of first group is higher than the end
When holding the group being currently accessed, the clustering paging message for responding first group is determined.
In another example, the terminal determines that this terminal is under the jurisdiction of first group, and the clustering paging message is taken
Tape terminal needs the instruction information responded, the terminal to be in connected state, and the priority of first group is higher than the terminal
The group being currently accessed, and the terminal receives the user instruction for accessing first group.Compared with preceding example, originally show
Example terminal change access group when, user can be prompted, receive user instruction be linked into the instruction of the first group when,
Just determine the clustering paging message for responding first group.
Step 130, the terminal sends the first pilot tone to the base station, and first pilot tone is allocated to described first group
The dedicated pilot for clustered paging response of group.
In LTE system, the first pilot tone that terminal is sent, is the random access guiding sent in random access procedure
(Random Access Preamble), i.e. MSG1.
Terminal can obtain first pilot tone for distributing to first group in several ways.
In one example, dedicated pilot is distributed to multiple groups by base station in advance.Base station by system broadcast message to
Terminal sends the distribution information that base station is pre-assigned to the dedicated pilot for clustered paging response of group, the dedicated pilot
There are one or it is multiple, each dedicated pilot distributes to one or more groups, and the distribution information includes dedicated pilot and special
Correspondence between the group distributed to pilot tone, specifically can with the correspondence between pilot identification and group identification come
It indicates.In this example, before the terminal returns to the first pilot tone to the base station, the terminal receives system broadcast message,
First pilot tone of first group is distributed to according to the distribution acquisition of information of the dedicated pilot.
For example, base station is configured with 50 groups (including the first group), using 10 pilot tones as clustered paging
The dedicated pilot of response, 10 pilot tones can be averagely allocated to 50 groups, and each dedicated pilot distributes to 5 groups,
The distribution information of 10 dedicated pilots is notified terminal, terminal to determine the first group of response by base station by system broadcast message
After clustered paging response, the distribution information can be searched according to the identification information of the first group, the first group is distributed in acquisition
The first pilot tone realize and the clustered paging of the first group responded by sending first pilot tone.
In another example, base station is also that dedicated pilot is distributed to multiple groups in advance, but not by system broadcasts
Message informing terminal.Base station carries base station in the clustering paging message of the first group and distributes to the dedicated pilot of the first group i.e. the
One pilot tone.For example, 10 dedicated pilots are distributed to 50 groups by base station, the clustering paging message for sending the first group it
Before, it determines and distributes to the first pilot tone of the first group, this is carried in the clustering paging message of the first group of transmission and first is led
Frequently.Merge the case where sending if it is more than two clustered pagings, then instruction is needed to distribute to the special of the two or more group
With pilot tone, can there are one or it is multiple.In another example, the terminal can be from the clustering paging message of reception
In, obtain first pilot tone that the base station is pre-assigned to first group.
Pilot resources in base station are limited, and base station is that a dedicated pilot distributes to multiple groups, can save and lead
Frequency resource.

In example, the base station sends the distribution information of dedicated pilot not by system broadcast message.But in the first group of transmission
Clustering paging message in, carry base station and be pre-assigned to the first pilot tone of the first group.Terminal is if it is determined that response first group
The clustering paging message of group, so that it may directly to find the first pilot tone for distributing to the first group from clustering paging message, be used for
Clustered paging responds.
Step 220, the base station receives the first pilot tone of terminal transmission, and it is described to determine that first pilot tone is allocated to
The dedicated pilot for clustered paging response of first group；
After the signalling of bouquet paging message of base station, if terminal establishes the connection eated dishes without rice or wine, base can be worked as in upper transmission pilot tone of eating dishes without rice or wine
When station receives the first pilot tone, it is assured that first pilot tone is allocated to first group according to the distribution information
Dedicated pilot because the first group is carrying out clustered paging, thus can determine the clustered paging for receiving the first group
Response.
Step 230, the base station returns to clustered paging response to core net, carries the identification information of first group.
In this step, base station receives the first pilot tone of terminal transmission, determines that there are the compositions of the first group under this base station
After member's terminal, clustered paging response is returned to core net, the identification information of the first group is carried, indicates that there are first under this base station
Group membership's terminal of group.Base station can also carry the group-calling service number of the first group for terminal distribution downlink shared resource
According to.If the base station is not received by the clustered paging response of first group, clustered paging response can not be returned,
And it is not terminal distribution downlink shared resource.
In the present embodiment, in the case where a pilot tone distributes to multiple groups, if base station receives the pilot tone, really
Surely the trunked call response of the current group for carrying out clustered paging in the multiple group that the pilot tone is distributed to is received,
In the multiple group the current group for carrying out clustered paging can there are one or it is multiple.For example, the base station in advance will
When dedicated pilot for clustered paging response distributes to group, first pilot tone is distributed to including the first group
Multiple groups；After then the base station receives the first pilot tone that terminal is sent, described in being determined according to the distribution information
First pilot tone is allocated to except the dedicated pilot of first group, also judges the multiple group that the first pilot tone is distributed to
In, whether there are other groups currently carrying out clustered paging in addition to first group, if any, the base station to core
In the clustered paging response that net returns, the group identification of other groups is also carried.Because if what the first pilot tone was distributed to
In the multiple group, there are other groups currently carrying out clustered paging in addition to first group, then the first pilot tone
May be that group membership's terminals of other groups is sent.
The embodiment of the present invention additionally provides a kind of base station, also can be found in Fig. 4, including memory 20, processor 10 and storage
On the memory 20 and the computer program that can be run on the processor 10, the processor 10 execute the calculating
The processing for the either method that base station as described in the embodiments of the present invention executes is realized when program.
According to the abovementioned embodiments of the present invention, after terminal clustering paging message of group belonging to receiving, response is such as determined,
Clustered paging response then is returned to base station, base station is allow to determine whether the cell under this base station has the group membership of the group whole
Group call region is limited in there are in the region of group membership's terminal, to avoid the waste of radio resource by end.And base station is sending group
After the clustering paging message of group, responded according to the clustered paging of terminal feedback to judge to whether there is under this base station the group of the group
Member terminal, and can be to core net signalling of bouquet page response, to assist core net to accurately control the hair that group exhales downlink data
Region is sent, radio resource is saved.Core net is responded according to the clustered paging that base station returns, so that it may be existed under which base station to know
Group membership's terminal of first group, to only exhale Establishing process and transmission data to the base station initiation group there are group membership's terminal.
In addition, above-described embodiment one proposes the mode that multiple groups share a dedicated pilot, the program can save
Pilot resources, and a good balance is obtained on saving pilot resources and accuracy to group membership's terminal positioning.And
When multiple groups share a dedicated pilot, base station is distributed to the dedicated pilot more when receiving the dedicated pilot
A group and the current group for carrying out clustered paging combine, and are identified as in multiple groups that the dedicated pilot is distributed to
The current group for carrying out clustered paging, can be further improved the accuracy of positioning.
