The justice touch-call of hot job (Mission Critical Push To Talk, abbreviation MCPTT) business, i.e., based on length
Phase evolution (Long Term Evolution, abbreviation LTE) broadband carries the trunked call to solve the problems, such as emergency communication field,
Its carrying can use MBMS technologies.Emergency communication field includes public safety class application (such as fire alarm and public security system) and leads to
(such as railway and city underground system) is applied with commercial class.As shown in Figure 1, when terminal device is more in existing MCPTT business
Industry is realized between different MA in the coverage (MBMS Service Area, abbreviation MSA) of media broadcast/multicast service
Successional method of being engaged in is, when terminal device is moved to B points inside MA from A points, the mobility of MBMS cluster downlinks by
Existing RAN technologies ensure.When terminal device is moved to non-MBMS regions C points from MBMS regions A points, i.e., from MBMS multicasts
When area is moved to non-MBMS multicasts area, communication system can be by the way that in signal detection technique of eating dishes without rice or wine, unicast be reconstructed in boundary point so that
Terminal device uses unicast reception signal after multicast area is detached from, and then ensures the continuity of group data downlink.
But when same group is planned in multiple MA cells, i.e., as shown in Figure 1 when terminal device is moved from the B points of MA1
When moving the D points of MA2, existing method is specially：Terminal device receives MA1 downlink multicasts.Then, server is adjudicated to MA1 frequencies
Rate signal weaker and less than after critical value, terminal system starts to reconstruct unicast, and the multicast downlink of terminal device unicast at this time all receives,
Terminal device gradually MA1 signal detections less than MA2 signals start to detect, but MA2 signals are very weak, at this time terminal device
Unicast reception downlink data is only used only.Gradually, MA2 frequency signals gradually become strong, and after certain critical value, terminal system is opened
Begin to delete unicast resource, terminal device receives downlink multicast at this time.
By above-mentioned it is found that the group defined in 3GPP cuts in communication process bearing resource in unicast and multicast at present
It changes, to ensure the technology of business continuance, in specific MBMS networking scenes, i.e. terminal device difference MA areas in MBMS regions
It when being moved between domain, needs to reconstruct unicast so that the bearing resource of group switches in unicast and multicast, and handoff procedure is answered
It is miscellaneous, and waste the communication resource.
In order to solve the above technical problem, the present invention provides a kind of LTE broadbands cluster communication method and device, technology clothes

Include the corresponding first flags of MA in MSA.
In the present embodiment, the first flag of each MA can be BMSC during MBMS carryings are established, be in MSA
Each MA configurations.Optionally, which can also be server as MA configurations, and the foundation carried by MBMS
Request is sent to BMSC.
After the MBMS carrying notices that BMSC is issued are received, each terminal device into MSA is sent for S104, server
Multicast signal, wherein, the multicast signal includes the first flag.
Specifically, after BMSC has established MBMS carryings, MBMS carrying notices are sent to server, server receives MBMS
After carrying notice, multicast signal is sent by the MBMS each terminal devices carried into MSA, MA is carried in the multicast signal
First flag.
S105, terminal device receive the multicast signal for the carrying first flag that server is sent.
Specifically, terminal device receives the multicast signal of server transmission, multicast letter is obtained from the multicast signal
Number carry first flag so that terminal device knows itself MA residing at this time according to the first flag.
For example, as shown in Figure 1, the mark that the first flag that the multicast signal received when terminal device carries is MA1, then
Terminal device, which can be known, is now placed in B points in MA1.Then, D point movement of the terminal device from the B points in MA1 into MA2,
Second moment was carried there are two first flag in the multicast signal that the server that terminal device receives is sent, and the of respectively MA1
The first flag of one mark and MA2 then illustrates that terminal device at this time is located at the intersection of MA1 and MA2.Then, terminal device after
Continue and moved to D points, at the third moment, the first flag carried in the multicast signal of server transmission that terminal device receives is
The mark of MA2, then terminal device, which is known, is now placed in MA2.
S106, terminal device send the monitor report for carrying the first flag to the server.

The first flag of MA1 of the device in the monitor report and the first flag of MA2, know that terminal device is now placed in MA1 and MA2
Intersection.
S108, server judge whether the number of first flag in each monitor report is more than or equal to predetermined threshold value,
The predetermined threshold value is the positive integer not less than 1.
S109, if so, the server determine in the form of multicast to the terminal device send signal.
Specifically, whether the number of first flag that server judges to carry in the monitor report that terminal device is sent is more than
Predetermined threshold value, the predetermined threshold value are the positive integer not less than 1, the i.e. positive integer more than or equal to 2.When server judges monitor report
When the number of the first flag of middle carrying is more than or equal to predetermined threshold value, then illustrate that terminal device is now placed in the boundary of multiple MA
Place.With reference to above-mentioned example, as shown in Figure 1, carrying the first flag and MA2 of MA1 in the monitor report that server receives
First flag, server judge that the number of the first flag in the monitor report is equal to 2, illustrate that terminal device is now placed in MA1
With the intersection of MA2, can enter in the preferable MA2 of multicast signal, therefore server determines when terminal device continues to move to
Signal is sent to the terminal device in the form of multicast, without resettling unicast.And then it avoids in terminal device from one
During MA is moved to another MA, established due to server is of short duration detects that the multicast signal that terminal device receives is poor single
It broadcasts so that terminal device toggles the problem of communication resource is caused to waste between multicast unicast and unicast multicast and generates.
In the present embodiment, as shown in Figure 1, when the first mark in the monitor report that server detects terminal device transmission
The number of knowledge is less than predetermined threshold value, and (i.e. end when the signal of multicast signal that receives of terminal device is less than preset critical value
When end equipment is located at the location of C in Fig. 1), server instruction terminal system establishes unicast.

MBMS is carried to terminal device and is sent multicast signal, and terminal device obtains the multicast after receiving multicast signal from multicast signal
The first flag for the MA that signal carries, and the first flag carrying of MA is sent into server in monitor report, when server is sentenced
When the number of first flag in disconnected monitor report is more than or equal to 2, server determines to continue in the form of MBMS is carried to described
Terminal device sends signal.The method of the present embodiment, when first obtained in the monitor report that server is sent from terminal device
After the number of mark is more than or equal to predetermined threshold value, determine to continue to carry to terminal device with MBMS to send signal, and then avoid
During terminal device is moved from a MA to another MA, the multicast that terminal device receives is detected because server is of short duration
Signal difference and establish unicast so that terminal device toggles between multicast unicast and unicast multicast causes the communication resource unrestrained
The problem of expense, generates.
