Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of cluster multi call communication means and system, by setting the function that realizes group system parallel processing low priority traffice than common also low priority.
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, to satisfy the needs of constituent parts intercommunication.
In the present trunked communication system, each group comprises a group id ID and group call region, and wherein group call region is defined as the gang sub-district.The fix information that but these information all are some stores in attaching position register (HLR) and SIM card when opening an account, and be unrealized to group calling user's mobile management.
Fig. 1 is a group system core network architecture in the prior art, wherein:
There is user profile among the HLR, comprises that this user's international mobile subscriber identification code (IMSI), affiliated group ID tabulate (user can belong to 50 groups at most).
Gateway mobile switch (GMSC) links to each other with external network, and GMSC also links to each other with anchor mobile switch (Anchor MSC).
Anchor MSC is in charge of and safeguards a specific voice group call service (VGCS).
When relay MSC jumps a plurality of MSC at group call region, all MSC except that anchor MSC.It between anchor MSC and the relay MSC the tree-shaped relation of one-to-many.
Visited Location Registor (VLR) has the ID tabulation of organizing under user IMSI, this user.When the user roams, these information are copied from HLR come.
Comprised group ID and group call region in the Group Call Register (GCR), group call region lumps together with group ID and is called group call reference.Wherein with among the continuous GCR of anchor MSC the dispatcher tabulation relevant, relay MSC tabulation, the directly actuated cell list of anchor MSC have been comprised with this group call reference.The GCR that links to each other with relay MSC has then comprised the anchor MSC address relevant with this group call reference, the cell list that this relay MSC is controlled.
When receiving that request is initiated in group calling, anchor MSC inquires about this group attribute to the GCR that is connected.Obtain the cell list under dispatcher's tabulation, relay MSC tabulation and this MSC control.And then call scheduling person, call out relay MSC and set up group-calling channel for the sub-district under this MSC control, there is group calling to initiate by each sub-district user in the NCH group of notifications, and indicates its group-calling channel parameter so that the user monitors in the group.
After relay MSC is received the group calling request of anchor MSC, to the GCR inquiry cell list that is connected, in these sub-districts, set up group-calling channel, have group calling to initiate, and indicate its group-calling channel parameter so that the user monitors in the group by user in notification channel (NCH) group of notifications.
When initiating a group calling, one group of user in the specific region can join group calling simultaneously and monitor the talker.Can only there be a talker the same time, and after the talker had said, other user can both be by becoming the talker by PTT key (Push to talk).In communication process, Any user can own decision be left midway or join in the group calling midway, and the user who enters group call region can have notice and join in the group calls in several midway.
The talker can take the uplink group cal channel, monitors descending group-calling channel simultaneously; Network also can distribute an independently up-downgoing dedicated channel separately for the talker.But the hearer can only monitor descending group-calling channel.
In the technical scheme of prior art 1, each user has the priority of one or several speech, and present group system is supported 3 grades of User Priorities, promptly common (Normal), preferential (Privileged) and urgent (Emergency).Priority when priority has been stipulated the different user speech, when a lower user from occupying up-channel of priority was talked, the user of higher priority can interrupt his conversation, and oneself becomes the talker; If the user of several different priorities sends the up call request simultaneously simultaneously, network is accepted the highest user's of priority request so.All users have common priority, and there are preferential and urgent priority in certain customers, and acquisition preferential and urgent call power is separate, and the acquisition of priority needs the affirmation and the distribution of network.
The call priority of common priority is minimum, can be interrupted or seize by the calling of preferential and urgent priority, and preferential priority is lower than the priority of urgent call again, can be interrupted by urgent call.But generally speaking, the user must not use urgent priority, and urgent call only is used in very urgent situation, the network anxious indication of can feeling nervous on the paging channel of relevant range and dedicated channel simultaneously.
When different users made a call request, the priority level that network based each request is carried was authorized the highest user's speech of priority, other user of equal priority, and network determines by certain arbitration way who obtains up speaking right.But the user obtains can only transmit speech information after up, and as other user during in speech, other user can only send upstream request message.
When busy, have only the current talker's of priority ratio the high request of priority when up, terminal just allows to send; Network is also only authorized and is carried the high request user of the present speaker priority of priority ratio simultaneously.Standard is supported two kinds of methods that send the uplink rob request at present: 1, under 1.5 channels, all users' the request of seizing sends by the group call uplink channel; 2, under 1.0 channels, all requests of seizing send by Random Access Channel (RACH) channel.Any in concrete this dual mode of support, network can be broadcasted on NCH.
When up channel was idle, all up call requests sent by the group call uplink channel.
The up-downgoing group-calling channel of existing system, and dedicated channel can only be used for sending speech information and a spot of data service message, and can not be used for sending data service message separately.If send the normal use that low priority traffice can influence the mandarin sound business again at group-calling channel, in the group system calling procedure, the user just can not handle as GPRS (GPRS), short message service (SMS) and positioning service low priority traffices such as (LCS) like this.

Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
The said low priority traffice of this document can refer to be different from the other kinds business of voice service.
The present invention is lower priority of user A traffic set---A, the priority-level of A is lower than normal priority, be that the A business can be interrupted by any voice service request, simultaneously, according to the particularity of this A business, can set this business A and can only under the situation of present group call uplink channel idle, use.When the group call uplink channel idle, user terminal sends the up call request by the group call uplink channel, and priority level A is carried in call request.
As shown in Figure 2, be schematic flow sheet of the present invention, as seen from the figure, mainly may further comprise the steps:
S1, BSS are to user terminal broadcast upstream channel idle Indication message;
S2, user terminal are initiated the up call request of A priority, carry priority A in this up call request;
S3, BSS send the request authorization messages to this user terminal;
After network was received this call request, if present group call uplink is idle and do not have other call request of higher priority to exist, then network sent at the group calling down channel and authorizes (GRANT) message.
S4, user terminal are to BSS report of user information and requested service classification;
User terminal sends response message at the group call uplink channel after receiving the authorization messages of network, the class of service that this response message carries subscriber identity information and asked, and wherein asking classification is to set the A business of A priority.
S5, BSS send the up call request to MSC;
In this up call request, do not carry user profile, Request Priority not and relevant information such as requested service classification, so that network can be made corresponding judgment.
Carry out the standard authentication process between S6, MSC and the VLR;
Carry out the standard authentication process between MSC and the VLR, to described user profile and open the A business information and carry out authentication.
S7, MSC send the upstream request acknowledge message to BSS;
After authentication was passed through, MSC sent the upstream request acknowledge message to BSS.
S8, the busy indication of BSS broadcast upstream;
BSS in this up busy Indication message, carries the priority A of user A business, so that when having other user terminal to initiate service request, can make judgement according to precedence information to the busy Indication message of user terminal broadcast upstream.
S9, MSC set up the A service carrying channel for the user.
Network is after the legal identity of authentication user, and the class of service of asking according to the user is the channel resource of user's assignment response.
Among the present invention program, be 1.5 channel modes if the up channel of network support is seized, then network for the user distributes proprietary up-downgoing channel, the user is transmitting-receiving low priority traffice data on the dedicated channel that distributes; If it is 1.0 channel modes that the up channel of network support is seized, then CU group call uplink channel sends the low priority traffice request, utilize the group calling down channel to receive professional downlink data simultaneously, as option, the special use that also can set up this moment as 1.5 channels connects.
Among the present invention program, when the user uses low priority traffice (for example A business of She Dinging), user terminal only has alternately with local MSC, and needn't distinguish anchor MSC and relay MSC, and anchor MSC can not know priority that the user under other relay MSC the using A business as A.The low priority traffice of while user request does not relate to other users in the group when (as irrelevant or only relevant with certain customers with interior other users of group), network need not and carry User Priority A in the busy message of whole group call region downlink broadcast group call uplink, this moment, network was only in sub-district, user place or the busy message of BSC controlled area broadcasting group call uplink, carrying User Priority is A, and remains repetition group calling up channel idle message in other sub-districts.
If network is only in user place Cell Broadcast CB group call uplink channel busy message and to carry User Priority be A, the A interface between BSC and the MSC just can not be shared so; If instead network is wished sharing A interface resource between BSC and MSC, network can only take the precedence information A of message and user's A business at the BSC area broadcasting group call uplink at user place so.
For 1.5 channels, user's low priority traffice carries out in dedicated channel, and this moment, other users sent the same prior art of voice service request process.If the up channel free time then directly sends, if up channel takies, the priority of then new call request must be than the priority height of active user business.Therefore if when up busy message was carried User Priority and is A, other users must not send the up call request that priority is A.Equally, after BSC received that priority is higher than the setup requests of A, the priority that should temporarily interrupt subordinate user was the business of A.
Here interrupting that different business is had different meanings, is exactly the end of this business for circuit domain business, then just supspends the transmission of data for packet switch domain service, when waiting group call uplink idle or group calling can also continue this business after finishing.No matter but which kind of situation, when waiting group call uplink idle, the user can continue to initiate the call request that priority is A.
For 1.0 channels, the user utilizes group-calling channel to carry out low priority traffice, and busy message just sends the up call request at RACH if the user reads group call uplink, is higher than the current priority that accounts for up user but prerequisite is still the priority of new call request; If the user reads the group call uplink idle message, then directly send the up call request at the group call uplink channel, this moment sub-district, low priority traffice place BSC when receiving that priority that new setup requests is carried is higher than A, with above-mentioned 1.5 channels, the priority of interrupting this BSC area user is the business of A.
Among the present invention program, it is the group call uplink channel idle that the user uses the precondition of low priority traffice, and the user utilizes group call uplink to send the low priority traffice request.But being the business of A, priority sets up message not in whole group call region broadcasting.Therefore in group calling, the user of different sub-districts (or base station area) can initiate the low priority traffice request message simultaneously, does not disturb mutually; If but be 1.0 channels, and low priority traffice used the group calling down channel, and this moment, network can only be supported a low priority traffice request so.As shown in Figure 3, the low priority traffice of different districts can exist simultaneously, take at these sub-district group calling up channels, but the part beyond these sub-districts of group call region all is the group call uplink channel idle, as shown in Figure 3.
Simultaneously, the A of priority A is professional only to be needed local MSC to handle get final product, the non-voice class business of this class if not with group in whole other are subscriber-related, need not to distinguish anchor MSC and relay MSC, anchor MSC needn't know that also the priority under other MSC is the A business of A.
The mutual negotiation of MSC and UE is set up the process of low priority traffice and is handled according to the normal process of present network processes low priority traffice.
As shown in Figure 4, be a schematic network structure of the present invention, as seen from the figure, mainly comprise:
The attaching position register of storing subscriber information (HLR);
The Group Call Register (GCR) of storage group calling information;
And the MSC of leading subscriber business; This anchor MSC has BSS, and BSS is made up of a BSC and some Cell, under the MSC some BSS is arranged, and each MSC has one or several BSS under (comprising A-MSC and R-MSC), and a general MSC has the GCR and the VLR of an association.
The present invention is provided with the first precedence information memory cell in described HLR, be used to store first precedence information of user's first business, when described anchor MSC receives user's first service request, ask this user's first precedence information to described HLR, and be described user's allocation of channel resources may according to described first precedence information.
The present invention also is provided with the priority comparing unit at MSC, is used for relatively receiving professional priority.
When user's first business is carried out in the process,, then compare first priority and second priority by this priority comparing unit if receive second service request that priority is second priority:
When described first priority is greater than or equal to second priority, refuse described second service request;
When described first priority is lower than second priority, then interrupts first business, and be the second traffic assignments channel resource.
The present invention is by a kind of function that realizes group system parallel processing low priority traffice than common (Normal) also low priority.Like this when the user when using low priority traffice, do not influence the existing voice service of cluster.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
