Abstract
The present invention discloses a method for indicating usable channels for uplink access requests, which is used in a group system which simultaneously supports channel realizing methods of 1.0 and 1.5 versions of group systems. The method comprises the steps: when an uplink group call channel of a group is occupied, a network side of the group system sends messages to users in the group for the notice that the uplink group call channel is not currently usable; after the messages are received, the users in the group sends uplink access requests to the network side of the group system through an uplink channel; when the uplink group call channel of the group is not occupied, the network side of the group system sends messages to the users in the group for the notice that the uplink group call channel is currently usable; after the messages are received, the users in the group sends the uplink access requests to the network side of the group system through the uplink group call channel.
Description
Technical field
The present invention relates in wireless trunking communication system, seize the technology that up channel is talked, particularly a kind of method that sends up access request available channel of indicating.
Background technology
Wireless trunking communication system, hereinafter to be referred as group system, be a kind of less expensive of growing up in recent years, command dispatching and communication system more flexibly, be widely used in units such as government bodies, energy traffic, airport harbour, industrial and mining enterprises, fire-fighting police, water conservancy and military affairs, in order to satisfy the needs of constituent parts intercommunication.
It is voice group call service (VGCS) that group system provides the most basic business.VGCS allows the user to set up and belongs to a certain given service area and have the interior a plurality of users' of a cluster group of identical group id (ID) calling, described service area is made up of the sub-district that several belong to same mobile services switching centre (MSC) or different MS C, this VGCS adopts semiduplex mode, user during the calling in the cluster group can become the talker, but any one only allows a talker constantly, and other member is obedient person in this cluster group.
Fig. 1 carries out the schematic diagram of group-calling process for prior art: suppose that all users belong to a base station in the cluster group, distribute a pair of up-downgoing group-calling channel for when setting up group calling the user in this cluster group, by the speech of group emission mode, other users in this group are subjected to pattern to listen to the speech of speaker as the descending group-calling channel of obedient side in this group-calling channel by winding to one of them user as the uplink group cal channel of current speaker in this group-calling channel.The notification message of group-calling channel configuration is gone up broadcasting at down channel as notification channel (NCH).Talk as other up channels that the user of current speaker also can be distributed by the group system network side of cluster group.
The user of group system can belong to different cluster groups, and different cluster groups have different priority levels.In a cluster group, obtain the service feature of following different stage in order to make different user, in the cluster group, be provided with different priority levels to different users, set user's priority level is kept in the employed terminal of user:
1, the parameter difference that other user of different priorities is provided with in random access procedure in the cluster group, as: the different retransmission intervals with setting of the repeating transmission number of times of setting are different or the like, and then cause inserting the success rate difference;
When 2, other user of different priorities initiated the up channel access simultaneously in the cluster group, group system was judged according to its priority level, is preferably other user of high priority and distributes up channel;
When 3, the other user of low priority talked by up channel in the cluster group, the other user of high priority can interrupt the other user's of low priority speech, obtained up channel and talked.
In order to realize the 3rd, promptly the multipriority of introducing the user not after, the other user of high priority can be in the other user's speech of low priority be carried out, send up access request, interrupt the other user's of low priority speech and make the other user of high priority become the talker, just existing currently has speaker just in up channel speech, and how obedient side initiates the problem of up access request.Present implementation method mainly contains two kinds.
First kind of implementation method is 1.5 channel implementation methods of group system.
Speaker takies dedicated uplink channels, and obedient square tube is crossed the uplink group cal channel that distributes and initiated up access request when the group calling of cluster group is set up.When obedient square tube cross up access request that the uplink group cal channel initiates by the response of group system network side after, the group system network side discharges the dedicated uplink channels that speaker takies, for this obedient side distributes dedicated uplink channels, this obedient side takies the dedicated uplink channels of being distributed and talks.
Wherein, this method can be divided into two kinds of situations again: first kind, after the dedicated uplink channels that group system network side release speaker takies, to initiate should obedient side assigning to the uplink group cal channel and talking of up access request earlier, and will the side of understanding assign to the dedicated uplink channels of being distributed again and talk for this obedient square distributed after the dedicated uplink channels more by the time; Second kind, after the group system network side discharged the dedicated uplink channels that speaker takies, for after this obedient side distributed dedicated uplink channels, directly should understand just assigned to dedicated uplink channels and talks.Take after dedicated uplink channels talks in this obedient side, other users in the uplink group cal channel idle in this cluster group, this cluster group can send up access request by the uplink group cal channel.
Second kind of implementation method is 1 channel implementation method of group system.
Speaker takies the uplink group cal channel that is distributed when the group calling of cluster group is set up and talks, and the Random Access Channel (RACH) that obedient square tube is crossed in the cluster group is initiated up access request.But when the uplink group cal channel idle of cluster group, the user in the cluster group can also initiate up access request by the uplink group cal channel.Here initiate up access request by the uplink group cal channel and comprise two kinds of situations: no speaker in first kind of situation, current cluster group, uplink group cal channel idle; Second kind of situation has speaker in the current cluster group, and speaker takies the uplink group cal channel of its affiliated subdistrict, and the obedient square tube in other sub-districts is crossed the uplink group cal channel that distributes this sub-district and initiated up access request in the cluster group.Because the retardance of RACH is not as the uplink group cal channel, so initiate up access request in order to use the uplink group cal channel as much as possible, but the group system network side is when the uplink group cal channel time spent, the message that can send the uplink group cal channel idle by down channel can be initiated up access request to the user in the cluster group by the uplink group cal channel of free time after the user in the cluster group receives.
In actual applications, the group system network side can be supported this two kinds of implementation methods simultaneously, promptly supports two kinds of implementation methods of 1.5 channels and 1 channel simultaneously.When the user when the group system network side sends up access request, can take any one method in this two kinds of implementation methods arbitrarily to send.But the uplink group cal channel that distributes when all using group calling to set up owing to the implementation method of present 1.5 channels sends up access request, and unlike the implementation method of 1 channel, can send the message of uplink group cal channel idle by down channel, thereby make the user when supporting that simultaneously these two kinds of implementation methods send up access request, following problems occurred.Problem one: the user can't learn that current cluster grid side adopts the sort of implementation, thereby when not receiving the message of uplink group cal channel idle, do not know by the uplink group cal channel still to be to send up access request by the RACH channel by down channel; Problem two: if the group system network side adopts the implementation method of 1.5 channels, but adopt earlier and distribute the uplink group cal channel to speaker, when redistributing the processing procedure that dedicated uplink channels talks again, obedient side can't be by initiating up access request at the current uplink group cal channel that takies of speaker.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method that sends up access request available channel of indicating, this method not only supports the group system network side of 1.5 channel implementation methods and 1.0 channel implementation methods can indicate the user in the cluster group to use idle up channel to send up access request at the same time, and can solve the group system network side of supporting 1.5 channel implementation methods and 1.0 channel implementation methods at the same time and adopt the elder generation in the 1.5 channel implementation methods to distribute the uplink group cal channel to speaker, when redistributing the processing procedure that dedicated uplink channels talks again, obedient side can't initiate the problem of up access request by the uplink group cal channel that takies in speaker.
According to above-mentioned purpose, technical scheme of the present invention is achieved in that
A kind of method that sends up access request available channel of indicating, this method is applied in the group system of supporting 1.5 channel implementation methods and group system 1.0 channel implementation methods simultaneously, and this method comprises:
When the uplink group cal channel of cluster group is occupied, the user of group system network side in the cluster group sends the current unavailable message of uplink group cal channel, receives that the user in the cluster group of this message sends up access request by Random Access Channel RACH to the group system network side;
When the uplink group cal channel of cluster group is unoccupied, the user of group system network side in the cluster group sends the current available message of uplink group cal channel, receives that the user in the cluster group of this message sends up access request by the uplink group cal channel to the group system network side.
The current unavailable message of described uplink group cal channel is that the group system network side repeats to send, and this time interval that repeats to send is preestablished by the group system network side;
The current available message of described uplink group cal channel is that the group system network side repeats to send, and this time interval that repeats to send is preestablished by the group system network side.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, below lift specific embodiment and, the present invention is described in more detail with reference to accompanying drawing.
When the group system network side is supported 1.5 channel implementation methods and 1.0 channel implementation methods simultaneously, can regardless of the current use of group system network side be 1.5 channel implementation methods or 1.0 channel implementation methods, the up channel that the user in the cluster group sends up access request can only be the uplink group cal channel that distributes when setting up of group calling or the RACH in the cluster group.So, method provided by the invention is the implementation method of which kind of channel regardless of the current use of group system network side, can unify to use down channel to send Indication message indicates the user in the cluster group can use which kind of up channel to send up access request, after user in the cluster group receives Indication message by down channel, select to send the up channel of up access request according to Indication message.
Below send up access message available uplink channel with the group system network side of supporting 1.5 channel implementation methods and the 1.0 channel implementation methods simultaneously user in using 1.5 channel implementation methods indication cluster group respectively and use user in the 1.0 channel implementation methods indication cluster group to send up access message available uplink channel the present invention is described.
Fig. 2 ought support the user of group system network side in using 1.5 channel implementation methods indication cluster group of 1.5 channel implementation methods and 1.0 channel implementation methods to send the flow chart of up access message available uplink channel simultaneously for the present invention, its concrete steps are:
The speaker of step 200, cluster group takies the dedicated uplink channels of group system network side distribution and talks.
The time interval that repeats to send the current available message of uplink group cal channel is pre-set by the group system network side.
This down channel can be descending group-calling channel, NCH or other the idle down channels that distributes when group calling is set up.
After the obedient square tube of step 202, cluster group is crossed down channel and received the current available message of uplink group cal channel, send up access by the uplink group cal channel and ask to the group system network side.
Certainly, identical with prior art, the group system network side also can send the current priority level that takies the speaker of dedicated uplink channels by down channel, like this, obedient side is before sending up access request, can be relatively self priority level whether than the priority level height of speaker, if send up access request; Otherwise, do not send up access request.This content does not embody in Fig. 2.
After step 203, group system network side receive up access request, discharge the dedicated uplink channels that speaker takies, distribute dedicated uplink channels for the obedient side who sends up access request, this obedient side takies the dedicated uplink channels of being distributed and talks.
Certainly, identical with prior art, the group system network side is after receiving up access request, can judge earlier also whether the obedient side's who sends up access request priority level is higher than the priority level of speaker, if, carry out subsequent step, otherwise, do not respond the up access request of this obedient side transmission or cross down channel and send access failure message, end to this obedient square tube.In order to realize this step, the obedient side who sends up access request can carry the priority level of self when sending up access request, so that the group system network side obtains the priority level of this obedient side.These steps do not embody in Fig. 2.
In step 203, when distributing dedicated uplink channels for the obedient side who sends up access request, in order to reduce to seize the time delay that up channel is talked, can earlier the side that should understand be assigned to the uplink group cal channel of having distributed when group calling is set up talks, at this moment, the group system network side repeats to send the current unavailable message of uplink group cal channel by down channel to the user in the cluster group, and this message can be carried the information of sub-district, current disabled uplink group cal channel place.After distributing dedicated uplink channels for by the time the side that should understand, the subsequent step of talking and carry out step 203 to the dedicated uplink channels of being distributed in obedient side is somebody's turn to do in assignment again again.
User in the cluster group, when particularly not high than current upstream channel priority user receives the current unavailable message of uplink group cal channel, the information of the sub-district, current disabled uplink group cal channel place of carrying according to this message judges whether the sub-district at current unavailable uplink group cal channel place is self affiliated subdistrict, if then send up access and ask to the group system network side by RACH; Otherwise, then send up access and ask to the group system network side by the uplink group cal channel of when group calling is set up, distributing for this user self affiliated subdistrict.
When the cluster group is current when not having user from occupying up-channel to talk, the group system network side just repeats to send the current available message of uplink group cal channel by down channel, makes user in the cluster group can initiate up access request and carries out uplink rob.
Fig. 3 ought support the user of group system network side in using 1.0 channel implementation methods indication cluster group of 1.5 channel implementation methods and 1.0 channel implementation methods to send the flow chart of up access message available uplink channel simultaneously for the present invention, its concrete steps are:
The uplink group cal channel that the speaker of step 300, cluster group takies the group calling of cluster group distributes when setting up is talked.
The time interval that repeats to send the current unavailable message of uplink group cal channel is pre-set by the group system network side.
This down channel can be descending group-calling channel, NCH or other the idle down channels that distributes when group calling is set up.
After the obedient square tube of step 302, cluster group is crossed down channel and is received the current unavailable message of uplink group cal channel, the information of the sub-district, current disabled uplink group cal channel place of carrying according to this message judges that whether the sub-district at current unavailable uplink group cal channel place is the sub-district under self, if, execution in step 303; Otherwise, execution in step 304.
The obedient square tube of step 303, cluster group is crossed RACH and is sent up access and ask to change step 305 over to the group system network side.
The obedient square tube of step 304, cluster group is crossed when group calling is set up the uplink group cal channel of distributing for this user self affiliated subdistrict and is sent up access and ask to change step 305 over to the group system network side.
Before step 303 or step 304, the obedient side who also has cluster judges whether the priority level of self is higher than the priority level of speaker, if, then execution in step 303 or step 304; Otherwise, then do not send up access and ask to the group system network side.These steps do not embody in Fig. 3.
After step 305, group system network side receive up access request, discharge the current uplink group cal channel that takies of speaker, the obedient side who sends up access request is assigned to the uplink group cal channel talk.
Certainly, identical with prior art, the group system network side is after receiving up access request, can judge earlier also whether the obedient side's who sends up access request priority level is higher than the priority level of speaker, if, carry out subsequent step, otherwise, do not respond the up access request of this obedient side transmission or cross down channel and send access failure message, end to this obedient square tube.In order to realize this step, the obedient side who sends up access request can carry the priority level of self when sending up access request, so that the group system network side obtains the priority level of this obedient side.These steps do not embody in Fig. 3.
If the current CU uplink group cal channel that does not have in the cluster group, the group system network side just repeats to send the current available message of uplink group cal channel by down channel, make user in the cluster group can initiate up access request and carry out uplink rob that the implementation of this and prior art is identical.
Group system network side of the present invention can be the base station of each sub-district in the cluster group, the current available or current unavailable message of uplink group cal channel of described uplink group cal channel is that the base station of sub-district sends the channel that up access request should be used according to the cluster user under this sub-district of uplink group cal channel occupancy advisory of this base station by the base station decision of each sub-district in the cluster group.
The present invention works as the user and is receiving the current unavailable message of uplink group cal channel, and the sub-district of judging this current unavailable uplink group cal channel place is during for the sub-district under self, can not send up access request by RACH yet, and use other up channels in the cluster group to send up access request, send up access request as the idle up channel that uses the non-uplink group cal channel in the cluster group.
By method provided by the invention, user in the cluster group need not be concerned about the group system network side current be the implementation method that adopts the implementation method of 1.5 channels or adopt 1.0 channels, as long as before sending up access request, receive the whether available Indication message of uplink group cal channel, thereby determine to adopt any bar up channel to send up access request by down channel.By technical scheme provided by the invention, can support the group system network side of 1.5 channel implementation methods and 1.0 channel implementation methods can indicate the user in the cluster group to use idle up channel to send up access request at the same time.Further, the elder generation that can solve in the implementation method that the group system network side of supporting 1.5 channel implementation methods and 1.0 channel implementation methods at the same time adopts 1.5 channels distributes the uplink group cal channel to speaker, when redistributing the processing procedure that dedicated uplink channels talks again, obedient side can't be by initiating the problem of up access request at the current uplink group cal channel that takies of speaker.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
