The present invention relates to the concentrated area is stored in the method and the corresponding communication device of the communication equipment that program information in the communication network and/or job information be transferred to a plurality of dispersions.
Background technology
In wireless communication networks based on wireless channel, especially in the wireless relay network of point-to-multipoint-also be known as " radio in the local loop (RLL) " or " wireless local loop (WLL) ", the network temination unit of a plurality of dispersions and/or the discrete communication equipment that is configured to network temination unit always are connected to base station-also be known as " wireless base station (RBS) " or " wireless carrier platform (RCS) " by one or more wireless channels.For example in Siemens AG Representation's document in 1996 " DECTlink Radio Access:Where Performance Counts (DECT link wireless access: where consider to carry out) " and Siemens AG Representation's document in 1997 " CDMAlink AWinner in any Terrain (winner in any landform of CDMA link) ", once told about the WLL relay system that is designed to wireless speech and data communication.
The relay system that above-mentioned document is told about always shows as a kind of wireless user's end, and it just can be realized at short notice cheaply to need not to lay wired connection line.The dispersion wireless communication unit RNT that distributes to each user links to each other with a trunking by transmission medium " wireless channel " respectively, and described trunking is connected to higher level's communication network PSTN, for example is connected to the fixed network ISDN towards ISDN.At this, described wireless channel designs according to dect standard or CDMA transmission method.Described trunking comprises that at least one stops central junction network equipment RBS described junction network air interface, that show as the base station or RCS realizes leading to the trunk network access device RDU that is connected of higher level's communication network with at least one.Described central junction network equipment and trunk network access device are connected with each other by copper cash, fiber waveguide or directed Radio Link.Need information transmitted for example according to HDSL (high bitrate digital subscriber line) transmission technology with the transmission rate of 2 mbit/for example-be also referred to as " 2 mbit/link "-transmit, wherein, described HDSL link comprises useful channel and 64 kilobit signaling channels by the common use of all discrete communication equipment of a plurality of 64 kilobits.All are arranged in scatternet terminal unit within the wireless range of described trunking or the signaling information of discrete communication equipment is transferred to described central junction network equipment by described signaling channel from described trunk network access device.
Described trunk network access device to the connection of higher level ISDN communication network is to realize by the standard interface of abideing by V5.1 or V5.2 standard.Described trunk network access device is by network management interface link to each other with a kind of central Network Management Equipment-be called as in given document " ONMS access concentrator ".Described network management interface for example is configured to Q or QD2 interface.Be provided for moving described trunking or move the function of described trunk network and be used to administer and maintain their function-be also referred to as OAM(Operation Administration Maintenance) (operation, management, safeguard) by described central network management unit.For the OAM information of controlling and the execution OAM(Operation Administration Maintenance) needs for example is transferred to described trunking by the QD2 interface or in the scope of snmp protocol (single NMP) by TMN interface (telecommunication management network) or OAM interface in the scope of QD2 agreement.
In the management process that in current WLL relay system, is realized, must be transferred to communication equipment within wireless range dispersed placement, that be positioned at described trunking to the version of the control of the running parameter that for example upgrades or job information or renewal or working procedure from the Network Management Equipment of centralized arrangement through described trunking.In current WLL relay system (such as the CDMA link of Siemens Company or DECT link), adopted, be used to transmit the program information of renewal and/or the method for job information (being also referred to as software download or software upgrading hereinafter) is based on: the communication equipment that according to priority updated information is transferred to each dispersion purely from central Network Management Equipment through trunking.At this, always set up point-to-point communicating to connect to the discrete communication equipment that needs upgrade from central Network Management Equipment, and then through the current program information of QD2 interface transmission.
In above-mentioned WLL relay system, shortcoming is the transmission capacity that the can be used for software download constraint that can be subjected to a plurality of capacity limit-be also referred to as " bottleneck ":
Provide the message transmission rate of 64 kilobits/second by Network Management Equipment through the QD2 interface, so that the program information of OAM and renewal and job information are transferred to described trunk network access device.The message transmission rate of described QD2 interface can not be extended.
In the scope of software download,, only provide the transmission capacity of 64 kilobits/second signaling channels of HDSL link for updated information is transferred to described junction network equipment from the trunk network access device.Owing to transmitting those through this signaling channel (below be also referred to as " IV5 C channel ") is that the discrete communication equipment within the wireless range of trunking of being arranged in attaches whole signaling informations of producing (below be also referred to as " IV5 signaling information "), so only some transmission capacity-Yue 5 kilobits/second-be used to software download in the described IV5 C channel.When the program information that upgrades when network management unit is transferred to discrete communication equipment, this will show as great capacity limit.
The described program information that is transferred to central junction network equipment through the IV5 of HDSL link C channel is transmitted to described discrete communication equipment through special OW signaling channel (also being known as " interconnection channel " or " OW channel " in DECT link or CDMA chain-circuit system) with corresponding current signaling information on the interface aloft subsequently.The message transmission rate that described OW signaling channel is had is 16 kilobits/second.

In order subsequently described interim program stored information sw ' to be downloaded to the communication equipment RNT1...n of each dispersion, respectively set up useful channel independent, that message transmission rate be 64 kilobits/second through junction network equipment RCS to corresponding discrete communication equipment RNT1...n from trunk network access device RDU by network management unit TMN control and connect.Preferably, to connect be as " the static calling ", also promptly do not have alerting tone ground to corresponding discrete communication equipment RNT1...n foundation for this data.Owing to having used the independent useful data channel of being located at the HDSL link HDSL between described trunk network access device RDU and the junction network equipment RCS to transmit described interim program stored information sw ', so avoided the interference effect of the signaling information that in the signaling channel of described HDSL link HDSL, transmits for substituting described signaling channel.Except the described program information sw of interim storage, this has also embodied another optimization step with respect to known Oftware updating method.
Be input among the described junction network equipment RCS program information sw ' subsequently-the useful channel connection that substituted OW channel-by a kind of 64 kilobits/second of setting up through air interface in the scope that " the static calling " connects is transferred to corresponding discrete communication equipment RNT1 ... n.Preferably, the program information sw ' that temporarily is stored among the described trunk network access device RDU also connects (being also referred to as " multi-point diffusion connection ") and is transferred to a plurality of discrete communication equipment RNT1 concurrently through junction network equipment RSC by " the static calling " of a plurality of parallel foundation simultaneously ... n is stored among them then.At this, utilize the number of " software download " that this mode realizes simultaneously concurrently to depend on the transmission capacity that is located at the HDSL link HDSL between described trunk network access device RDU and the junction network equipment RCS, and depend on the transmission capacity of described air interface and the number of users that communicates through this WLL relay system ACCESS.
In order to quicken software download, to carry out in the process of segmentation at the 7th layer of program information sw that realized, that need are transmitted of OSI Reference Model, the section size of packet can for example be increased to the 24K byte from 256 bytes so far.Need the section of data packets for transmission size by increasing, can reduce described discrete communication equipment RNT1 ... the signaling information that n is sent on up direction during executive software is downloaded, and especially can reduce the affirmation information that is transferred to described network management unit TMN.
As can be seen, the major advantage of software download shown in Figure 1 is, needn't change the processing procedure that is realized for acceleration needs the transmission of the program information sw of transmission in current WLL relay system.Therefore, the WLL relay system that the method that is used for software download shown in Figure 1 also can be applied to install, or be applied to the discrete communication equipment RNT1 of delivered ... in the n.By controlling from trunk network access device RDU to corresponding discrete communication equipment RNT1 by network management unit TMN respectively ... n sets up communication, and by transmission by network management unit TMN control program information sw, which discrete communication equipment RNT1 described network management unit TNM can take an overall view of on each time point at ... stored the program information sw that upgrades in the n, and at which discrete communication equipment RNT1 ... remain effective in the n based on the control program of " wearing out " program information swo.
Figure 2 illustrates the first embodiment modification of software download shown in Figure 1.Opposite with Fig. 1, be in described junction network equipment RCS, to have arranged intermediate store ZM in WLL relay system ACCESS shown in Figure 2.In the software download process-in Fig. 2, represent with the line arrow, the refresh routine information sw that is stored in the network management unit TNM is transferred to trunk network access device RDU by described QD2 interface QD2, and from this access device RDU through the useful channel of 64 kilobits/second of HDSL link HDSL and be sent to junction network equipment RCS, be stored in then in the intermediate store ZM of this junction network equipment RCS.
Owing in this embodiment modification, only need described refresh routine information sw is transferred to junction network equipment RCS from network management unit TMN once, so it should be noted that also can through WLL relay system ACCESS other, for example provide the transmission channel of less transmission capacity to transmit described program information sw.
For the program information sw ' in the intermediate store ZM that is stored in described junction network equipment RCS is transferred to corresponding discrete communication equipment RNT1 ... n has used through broadcast channel and has sent to all discrete communication equipment RNT1 from described junction network equipment RCS ... the broadcast of n-also be known as broadcasting method.In the scope of broadcasting method, for example can use " slow broadcast channel, SBCH " for the program information sw that transmission is upgraded.In current WLL relay system (such as the DEC link of Siemens Company or TDMA link), adopt described slow broadcast channel SBCH to come call transmission information and such as transmission system time.In this embodiment modification, still idle transfer resource is used to by broadcasting method described program information sw is transferred to the communication equipment RNT1 of each dispersion among the described slow broadcast channel SBCH ... n.Because for program information sw is transferred to discrete communication equipment RNT1 from relaying network equipment RCS ... n and do not use and be arranged in described discrete communication equipment RNT1 ... the useful channel of the air interface between n and the junction network equipment RCS is so avoided the additional resource load of RLL relay system ACESS and caused performance loss thus.
Preferably with described program information sw segmentation, or be divided into single packet, send by described slow broadcast channel SBCH successively then, wherein, the program information sw that is sent out is received and is stored in corresponding discrete communication equipment RNT1 group by group ... in the n.The packet that reception may make mistakes can receive when next sending by the program information of segmentation again, and is stored under the correct situation of reception at corresponding discrete communication equipment RNT1 ... in the memory MEM of n.Described at least one control program of representing with program stored information sw for example can be initialised in the scope of broadcasting method or start.
From discrete communication equipment RNT1 ... n sends to the affirmation information of junction network equipment RCS or network management unit TMN-for example about the information such as program version of confirming successfully to receive packet or be updated about successful initialization-may cause higher signaling-information amount at up direction.For at described discrete communication equipment RNT1 ... the n side avoids occurring the signal flood peak, can be transferred to described discrete communication equipment RNT1 to current program information through slow broadcast channel SBCH in the scope of broadcasting method by described mode and method ... n; For next activate or initialization those be stored in each discrete communication equipment RNT1 ... present procedure version in the memory MEM of n, this can be preferably by network management unit TMN by on purpose to corresponding discrete communication unit R NT1 ... " the static calling connects " that n sets up respectively realizes.
Fig. 3 shows the embodiment modification of software download based on broadcasting method shown in Figure 2.Opposite with Fig. 2, in method shown in Figure 3, current program information sw need not interim storage and just is transferred to junction network equipment RCS from network management unit TMN through trunk network access device RDU.The program information sw that is transferred to junction network equipment RCS is inserted in the scope of broadcasting method in the broadcast of the slow broadcast channel SBCH transmission of described warp subsequently, is transferred to corresponding discrete communication equipment RNT1 then ... n is shown in the line arrow.At this, the speed of transfer of data and especially to be stored in reading of program information sw in the network management unit TMN be that message transmission rate with slow broadcast channel SBCH is complementary.If for the former of memory location thereby can not in described trunk network access device RDU or junction network equipment RCS, keep in the described program information sw that is transmitted, just so for example can adopt this described software download that needs the program information of transmission of interim storage in trunking ZE that need not.The advantage of this embodiment modification is, the transmission capacity that is provided by transmission medium " wireless channel " has been be provided.By using broadcasting method, can significantly reduce with respect to progressive download method (for example connect or multi-point diffusion connects) in whole WLL relay system ACCESS, carrying out software upgrading needed download time by signal.For example can manage the communication equipment RNT1 of 50000 dispersions by network management unit TMN ... n.By method shown in Figure 3, even if under the more situation of number of users, also can in several hours, finish described discrete communication equipment RNT1 ... the software upgrading of n.In this case, the needed for this reason time is for example depended on the section size of packet, the error correction method type that adopts and quality of transmission medium " wireless channel " FK or the like.
Figure 4 illustrates the another embodiment modification of the inventive method, wherein, describedly need send to corresponding discrete communication equipment RNT1 from network management unit TMN ... the program information sw of n is temporarily stored among the intermediate store ZM who is arranged within the junction network equipment RCS.Use in the software download process shown in the line arrow at Fig. 4, the interior program information sw of memory MEM that leaves network management unit TMN in is transferred to described trunk network access device RDU by QD2 interface QD2, be transmitted to junction network equipment RCS from this equipment RDU through the useful channel of 64 kilobits/second of HDSL link HDSL then, and be stored in the intermediate store ZM temporarily.Preferably, come transmission procedure information sw by the useful channel of 64 kilobits/second that uses the HDSL link HDSL that between trunk network access device RDU and junction network equipment RCS, is realized, do not need the transfer resource of the signaling channel of this HDSL link HDSL, so avoided that the performance to WLL relay system ACCESS causes negative effect during executive software is downloaded.
Owing in this embodiment modification, only need once refresh routine information sw to be transferred to junction network equipment RCS from network management unit TMN, so it should be noted that also can by WLL relay system ACCESS other, for example provide the transmission channel of less transmission capacity to realize the transmission of this program information sw.
In embodiment modification shown in Figure 4, the interior program information sw of intermediate store ZM that temporarily is stored in junction network equipment RCS is respectively by being positioned at network management unit TMN and corresponding discrete communication equipment RNT1 ... point-to-point connection between the n (single broadcasting connects) is transferred to the communication equipment RNT1 of each dispersion ... n's.This syndeton is controlled by network management unit TMN.Preferably, the interim program stored information of described quilt sw also can be transferred to the communication equipment RNT1 of a plurality of dispersions simultaneously simultaneously by the point-to-point connection (multicast connection) of a plurality of parallel structures ... n realizes further reducing the time cost that is used for software upgrading thus.
By network management unit TMN control the program information sw ' that temporarily is stored in the junction network equipment RCS is transferred to each discrete communication unit R NT1 ... n also can realize in the scope of two kinds of transmission plans, tell about them below.
According to the first transmission plan modification,, wherein, be a kind of corresponding business type information of CDMA link-definition " software download " of current WLL relay system ACCESS-such as Siemens Company for software upgrading or software download are provided with a kind of new type of service.In order on purpose the program information sw in the intermediate store ZM that is stored in described junction network equipment RCS to be sent to the communication equipment RNT1 of certain dispersion temporarily ... n transmits corresponding business type information " software download " from network management unit TMN to trunk network access device RDU.In trunk network access device RDU, resemble the traffic type information " software download " of handling input the incoming call, wherein, identification sends it to junction network equipment RCS then from the traffic type information " software download " that network management unit TMN sends.If receive traffic type information " software download ", then from relaying network equipment RCS for example through broadcast channel or signaling channel to relevant discrete communication equipment RNT1 ... n transmits the respective call information of some indications " software download ".This call information that sends has for example been represented from corresponding discrete communication equipment RNT1 ... the data channel that n sets up one 64 kilobits/second to network management unit TMN connect-also claim the B channel-indication.Connect call information is sent to relevant discrete communication equipment RNT1 from relaying network equipment RCS for substituting broadcast channel or signaling channel, also can alternatively use the OW channel that had existed already ... n.If receive the call information of indication " software download ", then at described discrete communication equipment RNT1 ... whether check can use the required transfer resource of software download in the n, or whether these resources are for example connected shared by the current useful channel of realizing through air interface.
