Abstract
The present invention relates to a method for a data transmission to several slave exchanges in a telecommunication system, the method in which the data is transmitted to the slave exchanges (DXT1 to DXT3) and an acknowledgement of the data reception is expected from the slave exchanges. To get a data transmission method which is more efficient and reliable than previously known methods, at least one slave exchange (DXT2) from which the acknowledgement is received is commanded to transmit said data to the slave exchange (DXT3) from which no acknowledgement is received, if one of the slave exchanges (DXT3) does not acknowledge the data reception.
Description
The present invention relates in the telecommunication system data be sent to the method for some slave exchanges, in the method data are sent to slave exchanges, and wait for the data reception acknowledgement of slave exchanges.This method also relates to a kind of telecommunication system, comprise a host exchange, and has the slave exchanges that transfer of data is connected with host exchange, in this system, host exchange comprises the transmitter installation that sends the data to slave exchanges, and from the receiver apparatus of slave exchanges confirmation of receipt message, and slave exchanges comprises the receiver apparatus that receives the data that host exchange sends, and after receiving data, send the transmitter installation of acknowledge message to host exchange.
The present invention the invention particularly relates to the transfer of data between the mobile communication system switch, although also can be applied to other connection.Below in conjunction with concrete mobile communication system, the present invention is described by example.
Provide in the mobile communication system of service to same subscriber board at some switches, need to send for example subscriber station information between the switch.When this situation occurs in operator for example or user oneself and has changed in the system relevant with its subscriber board the setting.Therefore, the described change information that is provided with must be sent to all switches that the described subscriber board of maintenance is provided with related data.If can't then may cause the data of relevant unique user platform in the different switch databases to occur mutually internally inconsistent to arbitrary switch transmission data of this information of needs.
In known solution, host exchange utilizes it to be connected all slave exchanges that data after will changing send to the described data of needs with telecommunications between the slave exchanges.Like this, slave exchanges upgrades its database, makes it identical with the new data that receives from host exchange, and confirms the reception of this new data to host exchange.Deficiency maximum in the known method is, if the transfer of data between host exchange and the slave exchanges connects temporary transient the interruption, then more new data can't send to described slave exchanges.Like this, the data in the data in the described slave exchanges and other slave exchanges are inconsistent, thereby stored the different parameters of described subscriber board in different switches.
The objective of the invention is to address the above problem, and provide a kind of than the more effective more reliable method that data is sent to slave exchanges of original method.This purpose realizes by method of the present invention, it is characterized in that, when one of slave exchanges is not confirmed Data Receiving, if at least one has to not from the connection of its slave exchanges that receives the confirmation from its slave exchanges that receives the confirmation, order described at least one slave exchanges to not sending described data from its slave exchanges that receives the confirmation.
The present invention is based on following thought, when the telecommunications of leading to one of slave exchanges connects interruption, data are sent to not from its slave exchanges that receives the confirmation by certain other switch, thereby other slave exchanges is used as optional distribution route.Method of the present invention can be applied to not know in advance the situation of switch interconnection mode.Therefore, great advantage of the present invention is than sending the data to slave exchanges in the past more reliably, because according to the present invention, can order all slave exchanges for example to send data to successively not from its slave exchanges that receives the confirmation, until there being a slave exchanges finally successfully to carry out transfer of data, so other slave exchanges can not needed to know in advance the switch situation that interconnects in the system as optional distribution route.This makes that the use of slave exchanges can be very flexible, because for example when system increases new switch, do not need to redefine optional distribution route.
The invention still further relates to a kind of system that can use the inventive method.Telecommunication system of the present invention is characterised in that, if host exchange does not receive the confirmation message from one of slave exchanges of having sent data to it, then host exchange transmitter installation transmission predetermined control message has the slave exchanges that connects to the transfer of data of host exchange at least one, this system comprises at least one slave exchanges, if having to host exchange, at least one slave exchanges do not connect from the telecommunications that it receives the confirmation the slave exchanges of message, then described at least one slave exchanges will send to host exchange does not receive the confirmation message from it described slave exchanges from the data that host exchange receives in response to the control messages that receives from host exchange.
The preferred embodiment of this method and telecommunication system requires in 2 to 4 and 6 to 10 open at related right.
Below in conjunction with accompanying drawing, describe the present invention in detail by the preferred embodiments of the present invention, in the accompanying drawings
Fig. 1 shows the flow chart of first preferred embodiment of the invention, and
Fig. 2 shows the block diagram of telecommunication system first preferred embodiment of the present invention.
Fig. 1 shows the flow chart of the inventive method first preferred embodiment.
In the frame A of Fig. 1, more new data is sent to all slave exchanges that need described data.Start a timer simultaneously.
In frame B, receive the affirmation that receives data from slave exchanges.
Check in frame C whether timer has shown the time that has surpassed for the confirmation of receipt reservation, promptly whether has surpassed time restriction Tref.
If surpassed the time that keeps for confirmation of receipt, then process proceeds to frame D, checks the affirmation that whether receives Data Receiving from all slave exchanges that sent data to it.If receive the affirmation of all slave exchanges, then transfer of data success, process proceeds to frame K.
On the contrary, if do not receive the confirmation from one of slave exchanges, then process proceeds to frame F from frame E, to not from its described slave exchanges that receives the confirmation (or a plurality of slave exchanges) data retransmission.
If data retransmission, then process proceeds to frame H from frame G, the slave exchanges that order exists transfer of data to connect, and promptly switch n sends the data to not from its slave exchanges that receives the confirmation.According to the present invention, do not need to know in advance whether to be had to telecommunications not to connect from its slave exchanges that receives the confirmation by the slave exchanges of command sending data.If there is no connect, then transfer of data is failed naturally, promptly still can't receive the confirmation.
In frame I, check whether never receive the confirmation from its slave exchanges that receives the confirmation.If receive the confirmation, then process proceeds to frame K.If do not confirm that still then process proceeds to frame J, check whether to have ordered to exist all slave exchanges that connect to not sending data from its slave exchanges that receives the confirmation.If not, then process is returned frame F, data retransmission, and order afterwards exists the next slave exchanges that connects to not sending data from its slave exchanges that receives the confirmation.
Exist all slave exchanges that connect to sending data if ordered once, then repeat this process, promptly order first slave exchanges to not from its slave exchanges data retransmission that receives the confirmation from its slave exchanges that receives the confirmation.According to the flow chart of Fig. 1, repeat this process until receiving the confirmation from all slave exchanges.Alternatively, can attempt carrying out transfer of data in the section in preset time, if data transmission fails is then alarmed to the Systems Operator.
In the flow chart of Fig. 1, suppose all slave exchanges of order successively to not sending data from its slave exchanges that receives the confirmation, simultaneously, attempt between each order, directly sending data.Very naturally only there is a kind of scheme to use method of the present invention.Alternatively, for example at first trial is directly to sending data from its switch that receives the confirmation, and order exists all switches of connection basically simultaneously to sending data from its slave exchanges that receives the confirmation after pre-determined number.
Fig. 2 shows the block diagram of a kind of preferred embodiment of telecommunication system of the present invention.Telecommunication system shown in Fig. 2 part can for example be the part of TETRA network (pan-European relay wireless system), although the present invention also can be applied to other connection.
The host exchange DXT4 of Fig. 2 has the transfer of data connection to DXT3 to L3 to slave exchanges DXT1 by transfer of data connection L1.Host exchange DXT4 and slave exchanges DXT1 can be the identical TETRA network switchs to DXT3.
Switch DXT1 operates necessary data to the database D B maintenance system among the DXT4, for example organizes information.Group information comprises one group or some groups of users' the information that for example often need communicate.Described user has been defined as in the system same group member.Therefore, be very easy to carry out for example group calls in several, i.e. the calling that can both hear of all group memberships.Single group group information can for example comprise
-group id
-group membership list (for example one group of user ID), and
Specify in-group zone, i.e. the information of the cell area of network support group operation
Group information always is stored in the host exchange (promptly in the ownership mobile telephone switch of this group), and in addition, this information copy is in all slave exchanges that satisfy following condition: have at least the network support of a sub-district should group work in the sub-district that its zone comprised.
Under the situation of Fig. 2, group information, promptly data can be upgraded in host exchange DXT4, perhaps upgrade in DXT3 at slave exchanges DXT1, send lastest imformation to host exchange DXT4 by slave exchanges, DXT4 then forward direction sends lastest imformation other switch to the described data of needs.
In data updating process, the transceiver unit 1 under Fig. 2 situation connects L1 by transfer of data and sends data to slave exchanges DXT1 to DXT3 to L3.Transceiver 1 in the slave exchanges receives data and it is stored among the database D B, sends acknowledge message to host exchange and confirms Data Receiving.
If for example when host exchange DXT4 shown in Figure 2 sent data to slave exchanges DXT1 to DXT3, telecommunications connection L3 was interrupted in the system shown in Figure 2, then slave exchanges DXT3 can't receive the data of issuing it.Because do not receive the confirmation in the scheduled time, so the transceiver unit 1 in the host exchange detects this situation from switch DXT3.Then, transceiver unit 1 in the host exchange repeats to the transfer of data of slave exchanges DXT3, in addition, transceiver unit 1 in the host exchange sends predetermined control message to slave exchanges DXT1, sends the data that receive from host exchange to slave exchanges DXT3 by this control messages order slave exchanges DXT1.According to circumstances different, the data that slave exchanges DXT1 must send to slave exchanges DXT3 can be included in the control messages, and perhaps slave exchanges DXT1 can retrieve described data based on this control messages from its database D B.
Fig. 2 shows does not have direct telecommunications to connect between slave exchanges DXT1 and the slave exchanges DXT3, thereby slave exchanges DXT1 can't send to the situation of slave exchanges DXT3 from the data that host exchange receives.According to the present invention, host exchange does not need the information of slave exchanges interconnection mode, has all slave exchanges that telecommunications connects but system's land wheel changes it, orders them to send the data to not from its slave exchanges that receives the confirmation.In these cases, the telecommunications that slave exchanges DXT1 does not arrive slave exchanges DXT3 connects, therefore, and data transmission fails.After the scheduled time after switch DXT1 transmits control message, host exchange detects the affirmation that receives not yet from slave exchanges DXT3.Then, transceiver unit 1 among the host exchange DXT4 repeats to the transfer of data of slave exchanges DXT3, in addition, transceiver unit 1 in the host exchange transmits control message to slave exchanges DXT2, will send to slave exchanges DXT3 from the data that host exchange receives by control messages order slave exchanges DXT2.Because having to the telecommunications of slave exchanges DXT3, slave exchanges DXT2 connects L4, so arrive the transfer of data success of slave exchanges DXT3 specifically.
If the transceiver unit 1 among the slave exchanges DXT3 receives the data of transmission, the same route that it utilizes it to receive data sends acknowledge message, promptly passes through slave exchanges DXT2 to host exchange DXT4.If host exchange receives described acknowledge message, it stops to attempt to the transfer of data of slave exchanges DXT3.
Obviously, foregoing description and correlation diagram only are used to illustrate the present invention.Except the above-mentioned user profile and the group information that provide by example, telecommunication system also comprises out of Memory, and the present invention also can be applied to these transmission of Information.To those skilled in the art, under the prerequisite that does not depart from the disclosed scope and spirit of the present invention of appended claim book, obviously many improvement and variation can be arranged.
