Abstract
The present invention discloses a method for a user to send an uplink access request in a cluster group, which comprises the steps: when a terminal used by the user receives a response message of a current uplink access request sent by a network side of a cluster system, the terminal determines the difference of a random number carried by the response message and a random number carried by the currently sent uplink access request; after an uplink channel busyness message sent by the network side of the cluster system is received in set time, according to a current uplink channel occupying user' priority information received from the cluster system, the set user's priority is compared with the current uplink channel occupying user's priority for determining whether the set user's priority is higher or not; if the set user's priority is higher, the terminal used by the user resends an uplink access request, and otherwise, the terminal used by the user decides the failure of the current uplink access. The method solves the problem that when users with different priorities send uplink access requests, the user with the high priority can not always occupy the uplink channel for speaking.
Description
Technical field
The present invention relates in wireless trunking communication system, seize the technology that up channel is talked, particularly a kind ofly realize that the user in the cluster group sends the method for up access request.
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 these three, user in the cluster group sends the up access request of carrying random number by employed terminal, after the group system network side is received this request, carry the response message of random number by the downstream message transmission, this downstream message can be the broadcast that sends by NCH.After the employed terminal of the user in the cluster group receives the response message that carries random number, judge whether the random number that random number that this message carries and the up access request that self sends carry is identical, if it is identical, then the employed terminal of user determines that the group system network side has responded the up access request that self sends, send up channel assignment request for the group system network side, request group system network side is used for speech for user's assignment up channel, after the group system network side was given user's assignment up channel, the user talked by the up channel of institute's assignment; If inequality, then the predefined time of the employed terminal wait of user, the time that sets was set according to the average response time of group system network side, as a second, in the time of this wait, no longer sent any message to the group system network side.
As described in top scheme, when the random number that the up access request that random number of carrying when group system network side response message and user self send is carried is inequality, the employed terminal wait of user set in advance during this period of time in, if the employed terminal of user receives the busy information of up channel that the group system network side sends by downstream message, then the employed terminal of user is to the user prompt access failure, the user receives the voice that the group system network side sends from descending group-calling channel by the descending group-calling channel of employed terminal demodulation; If the employed terminal of user does not receive the busy information of up channel that the group system network side sends by downstream message, then the employed terminal of user sends the up access of carrying random number once more and asks to the group system network side, distributes up channel to be used for speech to the request of group system network side.
Because when the employed terminal of user receives the busy information of up channel that the group system network side sends by downstream message, the employed terminal of user can be asked to the group system network side and no longer send the up access of carrying random number to the user prompt access failure.Therefore, might produce a kind of situation: the group system network side can respond the up access request that other user of low priority sends, and the up access request that other user of refusal high priority sends, and other user of high priority no longer sends up access request owing to receive the downstream message that carries the busy information of up channel in the predefined time, causes other user of high priority can't obtain other business service of respective priority when inserting cluster grid side.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of and realizes that the user in the cluster group sends the method for up access request, this method can solve when the other user of different priorities sends up access request can not guarantee that high-priority users takies the problem that up channel is talked, and makes other user of high priority obtain other business service of respective priority when inserting cluster grid side.
According to above-mentioned purpose, technical scheme of the present invention is achieved in that
A kind ofly realize that the user in the cluster group sends the method for up access request, for the user in the same cluster group is provided with different priority levels and is kept at respectively in the employed terminal of user, this method comprises:
When the employed terminal of user receives this up access request responding message that the group system network side sends, it is inequality to determine that random number that this response message carries and this send the random number that up access request carries, and after the information that the up channel that receives the transmission of group system network side in the time of setting hurries, according to the current the priority level information that takies the user of up channel that receives from the group system network side, whether more set user's priority level is higher than the current priority level that takies the user of up channel, if, the employed terminal of user sends up access request once more, otherwise the employed terminal of user is determined this up access failure.
The busy information of described up channel is that the group system network side sends by downstream message; Described current the priority level information that takies the user of up channel is that the group system network side sends by downstream message.
The described downstream message that is used to send the busy information of up channel is same downstream message with the downstream message of the priority level information that is used to send the current user who takies up channel.
Whether be higher than in described more set user's priority level before the current user's who takies up channel the step of priority level, this method also comprises:
Whether the user's that the employed terminal judges of user is set priority level is that the lowest priority in the cluster group is other, if the employed terminal of user is determined this up access failure; Otherwise whether the priority level of carrying out more set user is higher than the step of the current user's who takies up channel priority level.
Before current the priority level information that takies the user of up channel that described basis receives from the group system network side compared step, this method also comprised:
Whether the employed terminal judges of user receives current the priority level information that takies the user of up channel, if compare step; Otherwise the employed terminal of user is determined this up access failure.
Before described the priority level information that judges whether to receive the current user who takies up channel, this method also comprises:
Whether the user's that the employed terminal judges of user is set priority level is that the lowest priority in the cluster group is other, if the employed terminal of user is determined this up access failure; Otherwise, carry out the step of the priority level information judge whether to receive the current user who takies up channel.
After the employed terminal of user was determined this up access failure, this method also comprised:
The employed terminal of user is to this up access failure of user prompt.
The time of described setting is determined according to the average response time of group system network side.
From such scheme as can be seen, group system network side of the present invention also sends current the priority level information that takies the user that up channel talks by downstream message when sending the busy information of up channel by downstream message.When the employed terminal of user receives the busy information of up channel that the group system network side sends by downstream message and current the priority level information that takies the user that up channel talks, the employed terminal of user compares the current priority level that takies the user that up channel talks and set this user's priority level, judge whether to be higher than the current priority level that takies the user that up channel talks, if the employed terminal of this user sends the up access of carrying random number once more and asks to the group system network side; Otherwise the employed terminal of this user is again to the user prompt access failure.Because the employed terminal of user of the present invention is not to receive just definite this access failure of the downstream message that carries the busy information of up channel, but whether user's that will be further more set priority level and the current priority level that takies up channel determine this access failure again, thereby can constantly initiate up access request to obtain other business service of respective priority to the group system network side.Therefore, this method has solved when the other user of different priorities sends up access request can not guarantee that high-priority users takies the problem that up channel is talked, and makes other user of high priority obtain other business service of respective priority when inserting cluster grid side.

In order to realize the present invention, when the employed terminal of user receives the busy information of up channel that the group system network side sends by downstream message, the employed terminal of user is not directly to the user prompt access failure, but the current user's who takies up channel priority level and set this user's priority level is compared, judge whether to be higher than the current priority level that takies the user of up channel, if the employed terminal of this user sends the up access of carrying random number once more and asks to the group system network side; Otherwise the employed terminal of this user is to the user prompt access failure.Like this, just can guarantee that the group system network side can ceaselessly receive the up access request that the user higher than the current user's who takies up channel priority level sends, thereby the up access request that the employed terminal of the user that group system network side meeting processing priority is not high sends distributes up channel to be used for speech for the high user of priority level.In order to make the employed terminal of user receive current the priority level information that takies the user of up channel, group system network side of the present invention can send current the priority level information that takies the user of up channel by downstream message.
Fig. 2 sends the method flow diagram of up access request for the present invention realizes the user in the cluster group, and its concrete steps are:
User in step 100, the cluster group sends the up access request of carrying random number by employed terminal to the group system network side.
After step 101, group system network side are received this request, carry the response message of random number by the downstream message transmission.
After step 102, the employed terminal of user receive the response message that carries random number, judge whether the random number that random number that response message carries and the up access request that self sends carry is identical, if identical, changes step 103 over to; If inequality, change step 105 over to.
Step 103, the employed terminal of user determine that the group system network side has responded the up access request that self sends, and send up channel assignment request for the group system network side, and request group system network side is used for speech for user's assignment up channel.
After step 104, group system network side were given user's assignment up channel, the user talked by the up channel of institute's assignment.
Step 105, predefined time of the employed terminal wait of user,, in the time of this wait, no longer send any information to the group system network side as a second.
Step 106, the employed terminal wait of user set in advance during this period of time in, whether the employed terminal judges of user receives the busy information of up channel that the group system network side sends by downstream message, if, execution in step 107; Otherwise, execution in step 112.
Step 107, the employed terminal wait of user set in advance during this period of time in, whether the employed terminal judges of user receives current the priority level information that takies the user of up channel that the group system network side sends by downstream message, if, execution in step 108; Otherwise the employed terminal of user is determined this up access failure.
In order to realize the present invention, the employed terminal of user must compare this set user priority level and the current priority level that takies the user that up channel talks, so the employed terminal of user must be earlier obtained the information of the current user's who takies up channel priority level from the group system network side.Therefore, the present invention needs the group system network side to send current the priority level information that takies the user of up channel by downstream message.
The present invention can up channel is busy information and current the priority level information that takies the user of up channel be carried in the same downstream message and send by the group system network side, also can be carried in the different downstream messages order respectively or send by the group system network side simultaneously.
Whether the user's that step 108, the employed terminal judges of user are set priority level is minimum, if, execution in step 109.
Step 109, the employed terminal of user send the message of access failure to the user.
Step 110, user receive the voice that the group system network side sends from descending group-calling channel by the descending group-calling channel of employed terminal demodulation.
Current the priority level information that takies the user of up channel that step 111, the employed terminal of user are carried according to the downstream message that receives, whether the priority level of judging this set user is higher than the current priority level that takies the user of up channel, if, execution in step 112; Otherwise, execution in step 109.
Step 112, change step 100 over to, the employed terminal of user sends the up access of carrying random number once more and asks to the group system network side.
The random number that random number that the response message that the group system network side that the present invention receives when the employed terminal of user sends is entrained and the up access request that self sends are carried is not simultaneously, and after in the time of setting, receiving the busy information of up channel, the employed terminal of user can judge earlier also whether set user's priority level is minimum, if minimum, the employed terminal of user is just determined user's access failure; Otherwise, detect the current priority level that takies the user of up channel according to the current the priority level information that takies the user of up channel of receive again, judge whether to continue to send up access request in view of the above.
From such scheme as can be seen, the random number that random number that the response message that the group system network side that receives when the employed terminal of user sends is entrained and the up access request that self sends are carried is not simultaneously, and after in the time of setting, receiving the busy information of up channel, the employed terminal of user is not determined access failure immediately, but to know the current priority level that takies the user of up channel according to the current the priority level information that takies the user of up channel of receive, judge whether continue to send up access request in view of the above: if the current user who takies up channel has than this user Geng Gao or during with priority level that this user equates, the employed terminal of this user is just determined user's access failure, sends the message of access failure to the user; Otherwise the employed terminal of user continues to send up access request to the group system network side.Therefore, by method provided by the invention, solved the other user of a plurality of different priorities when initiating up access request, other user of higher priority may unaccepted problem, has guaranteed that other user of high priority enjoys the business service suitable with priority level.
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.
