Embodiment
For making the object of the invention, technical scheme and advantage express clearlyer, the present invention is remake further detailed explanation below in conjunction with accompanying drawing and specific embodiment.
The present invention proposes in a kind of trunked communication system to realize the dynamically method of reorganization, to guarantee the information synchronization of network side and end side in dynamic regrouping process.
Send dynamically reorganization request message, group and subscriber terminal authority that network side relates to dynamic reorganization based on dynamic reorganization request message by dispatching desk to network side.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 through network side to the reorganization user terminal after receiving dynamic reorganization acknowledge message, its objective is in order to upgrade the information of reorganization user terminal.At this moment, start dynamic shuffling information and upgrade timer, to guarantee upgrading in time of the reorganization 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 modification completion message to upgrade dynamic group that relates to and the state of recombinating user terminal of recombinating in the network side data storehouse, to upgrade to accomplish then to dispatching desk.So far the dynamic shuffling information of having realized user terminal and network side is synchronous.
In the dynamic reorganization of technical scheme of the present invention, the dispatcher of mandate can be through dispatching desk with several groups and/or several user terminals recombinate (hereinafter be referred to as designated group) in the group that another one existed; Also can several groups and/or the reorganization of several user terminals be generated a new group (hereinafter is referred to as interim group).When treating task termination or arriving the stipulated time, the dispatcher can delete group and/or the user terminal that adds in the group through dispatching desk, perhaps cancels interim group that reorganization generates.
In the present invention, network side will be reserved the interim group of the group number composition special number pond of some earlier.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 to distribute to other interim groups and use.
Accompanying drawing 1 is to realize the dynamically method flow diagram of reorganization 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.
Dynamically comprise reorganization object and operation mark in the reorganization request message, the object of wherein recombinating comprises group's group number and the user terminal number that dynamic reorganization 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, like table 1.
Table 1. is reorganization operation mark example dynamically
| Dynamically 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, base station, reorganization 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 (in Fig. 1, not marking).
Step 1021, network side are checked this dispatching desk and whether are had the right to initiate dynamically reorganization operation according to dispatching desk number and self stored scheduling relatives of Taiwan compatriots living on the Mainland property in the request message of dynamically recombinating; And the legitimacy of checking the group that is asked according to the group attribute of the group number in the dynamic reorganization request message and self storage; According to the user terminal number in the dynamic reorganization request message and self user terminals stored attribute nucleus legitimacy and 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 to 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 through the legitimacy authentication, then return error message to dispatching desk; If user terminal is arranged not through the accessibility authentication, then when these user terminals reach accessibility authentication condition, upgrades dynamic shuffling information.User terminal upgrades dynamic shuffling information and in step 103, specifies.
After the authentication completion to dispatching desk, reorganization object, network side writes its data storehouse to dynamic shuffling information again.Network side writes database to dynamic shuffling information and comprises the state that upgrades user terminal, 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 is designated as " to be updated " to these user terminal states; 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, in this group, increases the relative users terminal, and is designated as " to be updated " to these user terminal states; For cancelling interim group of operation, then be designated as " waiting to delete " to interim group dynamic defrag status, be designated as " to be updated " to the shuffling information update mode of this interim group membership in this group.
It should be noted that if user terminal is initiated group call request, but the dynamic defrag status of group is " waiting to delete " under this user terminal, then this group call request of network side refusal.
After step 1022, network side upgraded dynamic shuffling information, network side sent dynamically reorganization acknowledge message to dispatching desk, in this message, comprises legal reorganization object identity, reorganization object base station, place and operation mark.Legal reorganization object has referred to pass through the reorganization 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 reorganization acknowledge message, dispatching desk sends dynamic shuffling information update inquiry information through network side to the reorganization object, to upgrade the group number of legal reorganization object, starts dynamic shuffling information simultaneously and upgrades timer.
Receive of the prompting of the user terminal of dynamic shuffling information update inquiry information, the user of user terminal is informed in the reorganization operation through modes such as sound, light, electricity.
After receiving the reorganization object renewal group number of dynamic shuffling information update inquiry information, send the dynamic shuffling information that comprises the reorganization object identity to dispatching desk and upgrade response message.For after dynamically shuffling information upgrades timer expiry, dynamically shuffling information upgrades the reorganization object that response message is not still sent to dispatching desk, and dispatching desk sends dynamic shuffling information update inquiry information through network side once more.
Relate to legal reorganization object and carry out the renewal of dynamic shuffling information, concrete steps 1031,1032 and 1033 (in Fig. 1, not marking) as follows:
After the dynamic reorganization acknowledge message that step 1031, dispatching desk are sent according to network side is confirmed the reorganization object, dispatching desk indication network side direction in service area and after being in the authentication of open state legal reorganization 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 reorganization object; Then reset dynamic shuffling information of dispatching desk upgrades timer; And the legal reorganization object repeating step 103 to not responding, perhaps should interim group be cancelled until the response of receiving all legal reorganization objects.
Step 1032, network side send dynamic shuffling information and upgrade the user terminal of asking legal reorganization object to comprise 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 reorganization object are preserved or deletion action group number based on the operation mark that dynamic shuffling information upgrades in the 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 reorganization 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 and revise completion message to dispatching desk, comprising step 1041 and 1042 (in Fig. 1, not marking).
Step 1041, dispatching desk send dynamic shuffling information modify request messages to network side after receiving that response message is upgraded in the dynamic reorganization of reorganization object transmission, are convenient to network side and carry out dynamic shuffling information renewal to the reorganization object that has upgraded.
Step 1042, network side are carried out dynamic shuffling information and are upgraded and comprise that renewal has responded the reorganization Obj State responding the reorganization object, and take different measures to different dynamic reorganization operation mark to responding the reorganization 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 " waiting to delete " or in the group deletes a user terminal that responds 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 reorganization object.For example, in steps A dispatching desk to the dynamic reorganization of network side request reorganization object a, b, c and d; Network side is to all reorganization object authentications among the step B, but d is through authentication, and then network side upgrades the state of legal reorganization object a, b and c; Legal reorganization 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 reorganization object; Network side upgrades the state that has responded reorganization object a and b in step D.
Describe wired dispatching desk request in detail below by embodiment and in the TD-LTE trunked communication system, realize the dynamically step of reorganization.Fig. 2 is the embodiment of the invention realizes creating interim group in the TD-LTE trunked communication system a procedure sketch map, and wherein the corresponding step 101 of A (201-202) is that wired dispatching desk sends dynamically reorganization solicited message to the scheduling gateway of network side; The corresponding step 102 of B (203), the scheduling gateway obtains wired dispatching desk reorganization object information from enhancement mode home subscriber server eHSS, to wired dispatching desk and reorganization object authentication; The corresponding step 103 of C (204-208) is promptly upgraded dynamic shuffling information to the user terminal of recombinating through the quilt of authentication; After the corresponding step 104 of D (209-210), the user terminal of being recombinated were accomplished dynamic shuffling information renewal, the eHSS of network side upgraded dynamic shuffling information.
Wired dispatching desk request realizes that in trunked communication system the method for creating 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 scheme 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 group temporarily 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, be made as " to be updated " to the state of these user terminals.EHSS sends dynamically reorganization acknowledge message (Dynamic Regroupment ACK) through the scheduling gateway to wired dispatching desk subsequently, the tabulation that the E-eNodeB that comprise the group number that eHSS is interim set of dispense, reached at user terminal number tabulation that interim group comprises in the message at least, can reach the user terminal place forms.Can reach user terminal refers to be in open state and be in the user terminal in the service area.
If one or more user terminals are arranged not through the legitimacy authentication, like the user terminal number mistake, then eHSS also returns error message to wired dispatching desk except that 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 in dynamic reorganization affirmation (the Dynamic Regroupment ACK) message that receives, does not comprise those and do not start shooting and the user terminal number that is not in the service area in the user terminal tabulation.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 through 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) through 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 the reorganization user terminal number and the operation mark of the group number of interim group, response message renewal; Whether record reorganization user terminal has carried out information updating; After if dynamically shuffling information upgrades timer expiry; The dynamic shuffling information of not receiving some reorganization user terminal upgrades response message (Dynamic Regroupment Information Request Update Response); Reset dynamic shuffling information of then wired dispatching desk upgrades timer, to the user terminal of not receiving response execution in step 204 once more.This operation is periodically carried out according to dynamic shuffling information renewal length of timer, perhaps should organize until the response of receiving all reorganization user terminals temporarily and cancelled.
The tabulation that step 205, eMME are formed 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 connects the foundation completion; Send dynamic shuffling information update inquiry information (Dynamic Regroupment Information Request Update) through 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 and in the terminal, increase this interim group number and operation mark.
Step 206, reorganization user terminal are preserved the group number of interim group; Feed back dynamic shuffling information through E-eNodeB to eMME and upgrade response message (Dynamic Regroupment Information Request Update Response); Wherein comprise the group number of temporarily organizing under the reorganization user terminal in the message at least; Send the user terminal number of response; The group number of interim group and the user terminal number that sends response under the reorganization user terminal in the message are used for upgrading the dynamic shuffling information of network side eHSS.
Step 207, eMME upgrade response message (Dynamic Regroupment Information Request Update Response) to the dynamic shuffling information of scheduling gateway forwards, carry the group number of temporarily organizing under the user terminal, the reorganization user terminal number that sends response in the message at least.
Step 208, scheduling gateway upgrade response message (Dynamic Regroupment Information Request Updae 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.
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.Following 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 reorganization of dispatching desk request dynamic; But in the dynamic reorganization request message of step 201 and step 202, when adding group, also need carry designated group group number and the number and/or the user terminal number that are added group; Dynamically the reorganization request message need carry interpolation designated group group number and user terminal number when only adding user terminal.In to dispatching desk and reorganization object authentication, eHSS increases the groups or users terminal in designated group, and eHSS need not the distribution group number.The reorganization user terminal " adds group and/or user terminal " according to operation mark and preserves group number, and network side eHSS upgrades the state of reorganization user terminal in its data storehouse according to the response at terminal.In the process of whole interpolation group and/or user terminal, the operation mark in dynamically the recombinate request message and the update inquiry information of dynamically recombinating 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 dynamically the recombinate 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 the designated group group number, deleted group's group number and user terminal number, therefore in the dynamic reorganization request message of dispatching desk, also need carry the designated group group number, deleted group's group number and user terminal number; When only deleting user terminal, need designated group group number and user terminal number, therefore in the dynamic reorganization request message of dispatching desk, also need carry designated group group number and user terminal number.
After the reorganization of dispatching desk request dynamic, the scheduling gateway in the step 203, because dynamically the reorganization operation is deletion group and/or user terminal, does not therefore need eHSS distribution group number to wired dispatching desk and reorganization object authentication; The legitimacy authentication of user terminal is passed through; If the state of user terminal is " to be updated "; When promptly increasing user terminal in this group, the information of not preserving this group in this user terminal is then thought in the response of not receiving 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 reorganization acknowledge message of dispatching gateway; If user terminal state be " upgrading ", then eHSS is made as user terminal state " to be updated ", and the acknowledge message of dynamically recombinating of redispatching is carried 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 through 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 to dispatching desk and revise completion message, comprise the designated group group number in this message at least, deleted group's group number and deleted reorganization user terminal number.
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 be " to be updated ", promptly when interim group increase 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 accomplished, if all the reorganization user terminals in the interim group are all deleted, then the eHSS deletion was 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, be the update mode attribute through the shuffling information that in the database of network side, increases user terminal, and in the dispatching desk side dynamic shuffling information be set and upgrade the success that timer guarantees shuffling information and send to rate.If the update mode attribute display of reorganization user terminal is arranged not to be upgraded to the network side response message; Then dispatching desk periodically issues the information updating request message based on dynamic shuffling information renewal timer, and then improves the success rate that dynamic shuffling information is sent to the reorganization user terminal; After reorganization user terminal response message was upgraded, network side carried out corresponding renewal in database, guaranteed the information synchronization of network side and subscriber terminal side.In addition; If the reorganization 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 a user terminal of being recombinated a dynamic shuffling information, makes 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 reorganization.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
