Embodiment
For making the purpose, technical solutions and advantages of the present invention express clearlyer, the present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
The present invention proposes in a kind of trunked communication system to realize the dynamically method of restructuring, to guarantee the information synchronization of network side and end side in dynamic regrouping process.
Send dynamic reconfiguration request message by dispatching desk to network side, group and subscriber terminal authority that network side relates to dynamic restructuring according to dynamic reconfiguration request message. after authentication was passed through, network side upgraded the state of user terminal and sends dynamically to recombinate and confirms message to dispatching desk.
Dispatching desk sends dynamic shuffling information update inquiry information by network side to the restructuring user terminal after receiving dynamic restructuring acknowledge message, its objective is in order to upgrade the information of restructuring user terminal.At this moment, start dynamic shuffling information and upgrade timer, to guarantee upgrading in time of the restructuring dynamic shuffling information of user terminal.After the reorganization user terminal upgrades dynamic shuffling information, send dynamically reorganization to dispatching desk and upgrade group number.Dispatching desk sends dynamic shuffling information modify request messages to network side, sends dynamic shuffling information to dispatching desk and revises and finish message to upgrade in the network side data storehouse group that dynamically restructuring relates to and the state of restructuring user terminal, to upgrade to finish then.So far the dynamic shuffling information of having realized user terminal and network side is synchronous.
In the dynamic restructuring of technical solution of the present invention, the dispatcher of mandate can be by dispatching desk with several groups and/or several user terminals recombinate (hereinafter being referred to as designated group) in the group that another one existed; Also several groups and/or the restructuring of several user terminals can be generated a new group (hereinafter being referred to as interim group).When treating the task end or arriving the stipulated time, the dispatcher can delete group and/or the user terminal that adds in the group by dispatching desk, perhaps cancels interim group that restructuring generates.
In the present invention, network side will be reserved earlier the interim group of the group number composition special number pond of some.When creating interim group, network side selects a group number to distribute to this interim group from the number pond at random, treat that this interim group is cancelled after, network side is retracted to the number pond with this group number, can be used for distributing to other interim groups and use.
Accompanying drawing 1 is to realize the dynamically method flow diagram of restructuring in the trunked communication system, may further comprise the steps:
Step 101: dispatching desk is recombinated to the network side request dynamic.
Dispatching desk sends the dynamic reorganization request message that comprises dispatching desk number, reorganization object identity, operation mark at least to network side.
Comprise restructuring object and operation mark in the dynamic reconfiguration request message, the object of wherein recombinating comprises group's group number and the user terminal number that dynamic restructuring relates to.Operation mark comprise add group and/or user terminal, deletion group and/or user terminal, establishment is organized temporarily and cancel interim group, four kinds operate in the message and identify with 2 bits, such as table 1.
Table 1. is reorganization operation sign example dynamically
| Dynamic reorganization operation | Operation mark |
| Add group/terminal | 00 |
| Deletion group/terminal | 01 |
| Create interim group | 10 |
| Cancel interim group | 11 |
Step 102: network side is to dispatching desk and reorganization object authentication.
Network side carries out authentication according to the reorganization object identity to dispatching desk, reorganization object, after authentication is passed through, network side is updated to " to be updated " according to operation mark with legal reorganization Obj State, and is sent to the dynamic reorganization that comprises legal reorganization object identity, reorganization base station, object place, operation mark less and confirms message to dispatching desk.
Comprise that specifically the authentication of step 1021 and the state of step 1022 upgrade (not marking) in Fig. 1.
Step 1021, network side are checked this dispatching desk and whether are had the right to initiate dynamic reorganization operation according to the dispatching desk attribute of the dispatching desk number in the dynamic reconfiguration request message and self storage; And the legitimacy of checking the group that asks according to the group attribute of the group number in the dynamic reconfiguration request message and self storage; According to the user terminal attribute nucleus of the user terminal number in the dynamic reconfiguration request message and self storage legitimacy and the accessibility to the request user terminal.
Wherein, the legitimacy authentication comprises: check dispatching desk whether have the right dynamically to recombinate operation, check this group and whether can carry out this dynamically reorganization operation, and check the user terminal that will delete or add and whether belong to this designated group; Whether the accessibility authentication comprises: check this user terminal and whether be in open state and check this user terminal and be in the service area.
If network side to the dispatching desk failed authentication, is then refused this dynamic reconstruction service request; If group's legitimacy failed authentication that network side relates to dynamic reorganization operation, refusal is at the dynamic reconstruction service request of this group; If network side is then refused this dynamic reconstruction service request to all user terminal legitimacy failed authentications that dynamic reorganization operation relates to; If one or more user terminals are arranged not by the legitimacy authentication, then return error message to dispatching desk; If user terminal is arranged not by the accessibility authentication, then when these user terminals reach accessibility authentication condition, upgrades dynamic shuffling information.User terminal Regeneration dynamics shuffling information describes in detail in step 103.
To dispatching desk, the reorganization object authentication finish after, network side writes its data storehouse to dynamic shuffling information again.Network side comprises the state that upgrades user terminal to dynamic shuffling information write into Databasce, and correspondence is added group and/or user terminal, deletion group and/or user terminal, establishment is organized temporarily with cancel interim group four kinds different dynamic reorganization operations takes different concrete measures.
Dynamically the concrete measure of reorganization operation comprises: for adding group and/or user terminal operations, network side increases the respective user terminal in adding group's group, and these user terminal states are designated as " to be updated "; For deletion group and/or user terminal, network side is designated as " to be updated " to the user terminal state that relates in the group that will delete or cancel; For creating interim group operation, network side selects a group number to distribute to this interim group from interim group number pond at random, increases the relative users terminal in this group, and these user terminal states are designated as " to be updated "; For cancelling interim group of operation, then interim group dynamic defrag status is designated as " to be deleted ", the shuffling information update mode of this interim group membership in this group is designated as " to be updated ".
It should be noted that if user terminal is initiated group call request, but the dynamic defrag status of group is " to be deleted " under this user terminal that then network side is refused this group call request.
Behind step 1022, the network side Regeneration dynamics shuffling information, network side sends dynamically restructuring acknowledge message to dispatching desk, comprises legal restructuring object identity, restructuring base station, object place and operation mark in this message.Legal restructuring object has referred to pass through the restructuring object of legitimacy authentication and accessibility authentication, comprises validated user terminal and legal group.
The dynamic shuffling information of step 103, end side upgrades.
After receiving dynamic restructuring acknowledge message, dispatching desk sends dynamic shuffling information update inquiry information by network side to the restructuring object, to upgrade the group number of legal restructuring object, starts simultaneously dynamic shuffling information and upgrades timer.
Receive that the user terminal of dynamic shuffling information update inquiry information passes through the prompting of the modes such as sound, light, electricity, informs reorganization operation the user of user terminal.
After receiving the restructuring object renewal group number of dynamic shuffling information update inquiry information, send the dynamic shuffling information that comprises the restructuring object identity to dispatching desk and upgrade response message.For after dynamically shuffling information upgrades timer expiry, dynamically shuffling information upgrades the restructuring object that response message is not still sent to dispatching desk, and dispatching desk sends dynamic shuffling information update inquiry information by network side again.
Relate to legal reorganization object and carry out the renewal of dynamic shuffling information, concrete steps 1031,1032 and 1033 (not marking in Fig. 1) are as follows:
After the dynamic restructuring acknowledge message that step 1031, dispatching desk send according to network side is determined the restructuring object, dispatching desk indication network side direction in service area and after being in the authentication of open state legal restructuring object send dynamic shuffling information update inquiry information. meanwhile, start dynamic shuffling information and upgrade timer.
Dynamically the timing length of shuffling information renewal timer can be set by dispatching desk.When if dynamically shuffling information upgrades timer above timing length, also do not receive the response of legal restructuring object, then reset dynamic shuffling information of dispatching desk upgrades timer, and to the legal restructuring object repeating step 103 of response not, until receive the response of all legal restructuring objects or should interim group be cancelled.
Step 1032, network side send the user terminal that dynamic shuffling information update request comprises to legal reorganization object according to the dynamic shuffling information update inquiry information that dispatching desk sends.If user terminal is in idle (RRC_IDLE) state of Radio Resource control, then network side at first carries out paging to user terminal, user terminal and network side have been set up after Radio Resource control (RRC) is connected, and send dynamic shuffling information update inquiry information to user terminal again.
Step 1033, legal restructuring object are preserved or deletion action group number according to the operation mark in the dynamic shuffling information update request, and return dynamic shuffling information to network side and upgrade response message.Network side upgrades response message dynamically recombinating and is sent to dispatching desk.
Wherein, legal restructuring object is for adding group/user terminal, creating the group number that the interim operation mark of organizing is then preserved designated group or interim group; For deleting group/user terminal, cancelling interim group of group number of then deleting designated group or interim group.
The dynamic shuffling information of step 104, network side upgrades.
After dispatching desk receives that the dynamic shuffling information of reorganization object upgrades response message, send dynamic shuffling information modify request messages to network side, network side upgrades the reorganization Obj State, send dynamic shuffling information modification and finish message, comprising step 1041 and 1042 (in Fig. 1, not marking) to dispatching desk.
Step 1041, dispatching desk send dynamic shuffling information modify request messages to network side after receiving that response message is upgraded in the dynamic restructuring of restructuring object transmission, are convenient to network side and carry out dynamic shuffling information renewal for the restructuring object that has upgraded.
Step 1042, network side are carried out dynamic shuffling information and are upgraded and comprise that renewal has responded the restructuring Obj State responding the restructuring object, and take different measures for different dynamic reorganization operation signs to responding the restructuring object, comprising:
For add group and/or user terminal, operation is organized in establishment temporarily, network side is made as " upgrading " to a user terminal state that responds from " to be updated " in designated group or interim group; For deleting group and/or user terminal, cancelling interim group of operation, network side is the designated group of " to be deleted " or in the group user terminal of response is deleted temporarily at state; If all user terminals are all deleted in the interim group, then network side is deleted this and is organized temporarily and regain interim group number to the number pond.
In technical scheme of the present invention, the counterweight group objects carries out authentication and upgrades the state of restructuring object.For example, in steps A dispatching desk to the dynamic restructuring of network side request restructuring object a, b, c and d; Network side is to all restructuring object authentications among the step B, but d is by authentication, and then network side upgrades the state of legal restructuring object a, b and c; Legal restructuring object upgrades group number in step C, but dispatching desk has only been received the response message of a, b, and then a and b become and respond the restructuring object; Network side upgrades the state that has responded restructuring object a and b in step D.
Describing wired dispatching desk request in detail below by embodiment and in the TD-LTE trunked communication system, realize the dynamically step of restructuring. Fig. 2 realizes creating the procedure schematic diagram of temporarily organizing for the embodiment of the invention in the TD-LTE trunked communication system, wherein to be wired dispatching desk send dynamic restructuring request information to the scheduling gateway of network side to the corresponding step 101 of A (201-202); The corresponding step 102 of B (203), the scheduling gateway obtains wired dispatching desk restructuring object information from enhancement mode home subscriber server eHSS, to wired dispatching desk and restructuring object authentication; The corresponding step 103 of C (204-208) is namely to the reorganized user terminal Regeneration dynamics shuffling information by authentication; After the corresponding step 104 of D (209-210), reorganized user terminal are finished dynamic shuffling information renewal, the eHSS Regeneration dynamics shuffling information of network side.
Wired dispatching desk request realizes that in trunked communication system the method that creates interim group specifically may further comprise the steps:
Operation mark comprises interpolation group and/or user terminal, deletion group and/or user terminal in technical solution of the present invention, establishment is organized temporarily and cancel interim group four kinds, and operation mark is indicated the groups or users terminal storage or deleted dynamic shuffling information.
The scheduling gateway does not pass through the authentication that is added into interim group group, then dispatches the gateway refusal to this group's dynamic reconstruction service request; The scheduling gateway does not pass through the authentication of user terminal, then dispatches the gateway refusal to this user terminal dynamic reconstruction service request.
The scheduling gateway passes through wired dispatching desk and the group and/or the subscriber terminal authority that are added into interim group, then eHSS selects a number assignment to give temporarily group in the number pond of reserving at random, the shuffling information of interim group membership's user terminal is write this interim group, and in interim group, the state of these user terminals is made as " to be updated ".EHSS sends dynamically restructuring acknowledge message (DynamicRegroupment ACK) by the scheduling gateway to wired dispatching desk subsequently, the tabulation that the E-eNodeB that comprise at least the group number that eHSS is interim set of dispense, reached at user terminal number tabulation that interim group comprises in the message, can reach the user terminal place forms.Can reach user terminal refers to be in open state and is in user terminal in the service area.
If one or more user terminals are arranged not by the legitimacy authentication, such as the user terminal number mistake, then eHSS also returns error message to wired dispatching desk except aforesaid operations, comprises the user terminal number and the error reason that do not pass through authentication.
It should be noted that wired dispatching desk confirms in (DynamicRegroupment ACK) message in the dynamic reorganization that receives, do not comprise in the user terminal tabulation that those do not start shooting and be not in user terminal number in the service area.When these user terminal start-up loggings or get back to service area and carry out the position when upgrading, eHSS is according to they states of " to be updated " in interim group, point out wired dispatching desk by the scheduling gateway, wired dispatching desk execution in step 204 is upgraded the dynamic shuffling information of these user terminals.
Step 204, wired dispatching desk send dynamic shuffling information update inquiry information (Dynamic Regroupment Information Request Update) by the scheduling gateway to enhancement mode mobile management entity eMME, at least comprise interim group group number in the message, can reach the tabulation that the E-eNodeB at user terminal place forms, reached at the user terminal number tabulation that interim group comprises, notice eMME carries out dynamic shuffling information to these user terminals to be upgraded.
Wired dispatching desk can be according to restructuring user terminal number and the operation mark of the group number of interim group, response message renewal, whether record restructuring user terminal has carried out information updating, after if dynamically shuffling information upgrades timer expiry, the dynamic shuffling information of not receiving some restructuring user terminal upgrades response message (Dynamic Regroupment Information Request Update Response), then reset dynamic shuffling information of wired dispatching desk upgrades timer, to the user terminal of not receiving response execution in step 204 again.This operation is upgraded length of timer according to dynamic shuffling information and is periodically carried out, until the response of receiving all reorganization user terminals or should interim group be cancelled.
Step 205, the tabulation that eMME forms according to the E-eNodeB at interim group of group number in the dynamic shuffling information update inquiry information and Ke Da user terminal place, notice E-eNodeB is in the reorganization user terminal of RRC_IDLE state according to interim group of reached at the user terminal number that comprises tabulation paging, after treating that RRC connection foundation is finished, send dynamic shuffling information update inquiry information (Dynamic Regroupment Information Request Update) by descending NAS message to the reorganization user terminal, at least the group number and the operation mark that comprise interim group under the reorganization user terminal in the message, reorganization user terminal are dynamically recombinated and are upgraded the group number that comprises according to interim group under the reorganization user terminal in the message increase this interim group number and operation mark in terminal.
Step 206, restructuring user terminal are preserved the group number of interim group, feed back dynamic shuffling information by E-eNodeB to eMME and upgrade response message (Dynamic Regroupment Information RequestUpdate Response), wherein comprise at least the group number of temporarily organizing under the restructuring user terminal in the message, send the user terminal number of response, the user terminal number of the group number of temporarily organizing under the restructuring user terminal in the message and transmission response is for the dynamic shuffling information of renewal network side eHSS.
Step 207, eMME upgrade response message (DynamicRegroupment Information Request Update Response) to the dynamic shuffling information of scheduling gateway forwards, carry at least the group number of temporarily organizing under the user terminal, the restructuring user terminal number that sends response in the message.
Step 208, scheduling gateway upgrade response message (Dynamic RegroupmentInformation Request Update Response) to dynamic shuffling information and are forwarded to wired dispatching desk, carry the group number of the affiliated interim group of user terminal, the reorganization user terminal number of transmission response in the message at least.
Step 210, eHSS are by the group number of interim group in the dynamic shuffling information modify request messages, user terminal number and the operation mark upgraded of response message, with in interim group of correspondence the user terminal state that upgrades of response message be made as " upgrading " from " to be updated ", and feed back dynamic shuffling information modification to wired dispatching desk and finish message (Dynamic Regroupment Information Modify Complete), comprise at least the user terminal number of interim group group number and update mode in the message.
In technical scheme of the present invention,, except that creating interim group, also comprise and add group and/or user terminal, deletion group and/or user terminal and cancel interim group for dynamic reorganization operation.Lower mask body realizes adding group and/or user terminal, deletion group and/or user terminal to wired dispatching desk request or cancels the interim group of difference with the interim group of realization establishment being elaborated in trunked communication system.
For adding group and/or user terminal, equally also need the restructuring of dispatching desk request dynamic, but in the dynamic reconfiguration request message of step 201 and step 202, when adding group, also need to carry number and/or the user terminal number of designated group group number and added group; Dynamic reconfiguration request message need to be carried and be added designated group group number and user terminal number when only adding user terminal. in to dispatching desk and restructuring object authentication, eHSS increases the groups or users terminal in designated group, eHSS need not the distribution group number. and the restructuring user terminal " adds group and/or user terminal " according to operation mark and preserves group number, network side eHSS is according to the response of terminal, upgrade the state of restructuring user terminal in its data storehouse. in the process of whole interpolation group and/or user terminal, the operation mark in dynamic reconfiguration request message and the dynamic restructuring update inquiry information is " adding group/user terminal ".
Deletion group and/or user terminal process with create interim group difference comprise following some.In deletion group and/or user terminal process, the operation mark in dynamic reconfiguration request message and the update inquiry information of dynamically recombinating is " deletion group and/or user terminal ".In addition, in the step 201, when deletion group, need designated group group number, deleted group group number and user terminal number, therefore in the dynamic reconfiguration request message of dispatching desk, also need to carry designated group group number, deleted group group number and user terminal number; When only deleting user terminal, need designated group group number and user terminal number, therefore in the dynamic reconfiguration request message of dispatching desk, also need to carry designated group group number and user terminal number.
After the restructuring of dispatching desk request dynamic, the scheduling gateway in the step 203, because dynamically reorganization operation is deletion group and/or user terminal, does not therefore need eHSS distribution group number to wired dispatching desk and restructuring object authentication; The legitimacy authentication of user terminal is passed through, if the state of user terminal is " to be updated ", when namely increasing user terminal in this group, do not receive the response of this user terminal, then think the information of not preserving this group in this user terminal, so eHSS directly deletes this user terminal in designated group, issue the number that need not carry this user terminal in the dynamic restructuring acknowledge message of dispatching gateway; If user terminal state is " upgrading ", then eHSS is made as user terminal state " to be updated ", sends dynamically restructuring acknowledge message again, carries the number of this user terminal in this message.In reorganization subscriber terminal side information updating process, difference is in the step 206, the group number of reorganization user terminal deletion designated group, and feed back dynamic shuffling information by E-eNodeB to eMME and upgrade response message, wherein dynamically shuffling information upgrades the reorganization user terminal number that comprises the transmission response in the response message at least; And in step 210, the reorganization user terminal that eHSS will respond is deleted from designated group, and feed back dynamic shuffling information modification to dispatching desk and finish message, comprise designated group group number, deleted group group number and deleted reorganization user terminal number in this message at least.
In interim group process is cancelled in execution, with create interim group difference be following some: operation mark and the group number in the corresponding message is respectively " cancelling interim group " and cancels interim group of group number; The reorganization of dispatching desk request dynamic, the scheduling gateway to dispatching desk, the success of reorganization object authentication after, if the state of user terminal is " to be updated ", promptly when interim group increases user terminal, do not receive the response of this user terminal, then think the information of not preserving this group in this user terminal,, issue the number that need not carry this user terminal in the dynamic reorganization acknowledge message of scheduling gateway so eHSS directly deletes this user terminal in interim group; If user terminal state is " upgrading ", then eHSS is made as user terminal state " waiting to delete ".The reorganization user terminal " is cancelled interim group " according to operation mark and is deleted group number; The eHSS of network side upgrades in the dynamic shuffling information process, and after step 210 was finished, if all the reorganization user terminals in the interim group are all deleted, then eHSS deleted this interim group, reclaims the group number of this group, used so that this group number is distributed to other interim groups.
In technical scheme of the present invention, shuffling information by increase user terminal in the database of network side is the update mode attribute, if and in the dispatching desk side dynamic shuffling information is set and upgrades the success that timer guarantees shuffling information and send to rate. there is the update mode attribute display of restructuring user terminal not upgrade to the network side response message, then dispatching desk periodically issues the information updating request message according to dynamic shuffling information renewal timer, and then improves the success rate that dynamic shuffling information is sent to the restructuring user terminal; After restructuring user terminal response message is upgraded, network side carries out corresponding renewal in database, guaranteed the information synchronization of network side and subscriber terminal side. in addition, if the restructuring user terminal is arranged does not start shooting or out of reach, then when these user terminal start-up loggings or get back to service area and carry out the position when upgrading, network can carry out information updating to these user terminals, guaranteed to greatest extent to notify reorganized user terminal dynamic shuffling information, so that the interchange of user terminal is convenient in the group. the operation of network side operation and end side all can respond dispatching desk, guarantees that dispatching desk operator or keeper can in time understand the result of dynamic restructuring.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
