Embodiment
Among the present invention, set up the multicast group by OMC, controlled network element adds the multicast group of corresponding software package, realizes the reception of software kit.
As shown in Figure 3, the Oftware updating method of controlled network element of the present invention comprises:
Step 31 behind the reporting information that OMC receiving slave network element sends, is determined the upgrade software bag according to reporting information, and described upgrade software bag is the software kit that is higher than the existing software version of controlled network element;
Step 32, OMC sets up the multicast group of upgrade software bag correspondence, and notifies controlled network element with the multicast group of upgrade software bag correspondence;
Step 33, controlled network element adds the multicast group, communicates based on multicast protocol with OMC, receives the upgrade software bag from OMC.
At this, this controlled network element can send reporting information by the version file downloading request message, also can send by other message.
At this, the employed multicast protocol of the inventive method can be various types of multicast protocols, but in order to guarantee the transmission reliability of mobile communication system, uses RM (ReliableMulticast, reliability multicast) related protocol in the specific embodiments of the invention.
In the step 32, need determine to supply the upgrade software bag of controlled network element upgrading according to the reporting information of controlled network element, at this, this reporting information comprises the information of the existing software version of controlled network element at least, at this moment, according to the information (software version sequence number) of the existing software version of this controlled network element, the upgrade software bag of selecting to be higher than the existing software version of controlled network element from software kit gets final product.
Yet along with the continuous evolution of access network technology, huge variation has taken place in its framework.
In the LTE system, the base station can be divided into Macro-BS and Home-BS two kinds, and (Macro-BS is mainly used in outdoor covering, Home-BS then is used for indoor covering), the design object of these two kinds of base stations and characteristic have bigger difference, thereby the support software of its operation can be different two types, promptly is used for the type of Macro-BS and is used for the type of Home-BS.
In the B3G system as the evolution of LTE system, covering performance and throughput performance for further enhanced system, between its BS and travelling carriage, introduced trunk desk by eating dishes without rice or wine to connect, and trunk desk is as controlled node, its software needs upgrading equally, so that guarantee the optimum of entire system performance.
Therefore, determine mistake to occur by the upgrade software bag iff the information that has software version by controlled network element now, therefore in the method for the present invention, the type information that further comprises controlled network element in the reporting information of controlled network element is to distinguish different controlled network elements.
OMC selects version to be higher than the upgrade software bag of the existing software version of controlled network element according to the information of the type information and the existing software version of controlled network element of controlled network element from the software kit set of controlled network element correspondence.
Simultaneously, existing controlled network element is under the identical situation of function, its ability (as the hardware platform ability) has difference, be in the controlled network element of the same type under the same OMC, the ability support of part controlled network element is than the software of higher-version, and the ability of other a part of controlled network element can't be supported the software of highest version.
Therefore, for fear of the software upgrading problem of bringing owing to the capacity variance of controlled network element, in the specific embodiments of the invention, the ability information that further comprises controlled network element in the reporting information of controlled network element, OMC is according to the information of type information, ability information and the existing software version of controlled network element, from the software kit set of controlled network element correspondence, select its ability to support, and version is higher than the upgrade software bag of the existing software version of controlled network element.
When in the reporting information of controlled network element, comprising the information of controlled network element type information and existing software version, OMC saved software bag is preserved according to controlled network element type and software version, and sets up corresponding multicast group according to controlled network element type and software version.
The IP address information of controlled network element can be passed through DHCP (Dynamic Host ConfigurationProtocol, DHCP) process and obtain;
And controlled network element points to the addressing of OMC, can be by default configuration, or retrain the address that obtains related service OMC indirectly based on the region by the information of " postcode " type.
Complete software upgrade process to controlled network element is described in detail below.
When controlled network element is the base station, utilize the complete software upgrade process of controlled network element of the inventive method to comprise:
Step 401, BS adds network and energising starts;
Step 402, BS sends reporting information, and receives and preserve the reporting information of BS by OMC, and this reporting information comprises: hardware version information, NE type information, existing software version information;
Step 403, after the BS reporting information that OMC carries out a period of time is collected (reducing the appearance of fragmentary responding scene), OMC comprehensively adjudicates based on the reporting information of BS as far as possible, determine whether to be BS upgrade software bag, upgrade if desired, then enter step 404, otherwise return step 402;
In step 403, OMC makes a strategic decision based on the reporting information of BS whether the software kit of suitable version is provided for this BS, and it is as follows that it upgrades required satisfied condition:
In the set of the pairing software kit of the NE type of BS, comprise that version is higher than the existing software version of BS, and the software kit that can support of the hardware capabilities of BS.
Step 404, OMC is the software kit that BS selects suitable version, at this, OMC chooses from the set of the pairing software kit of the NE type of BS that hardware capabilities can support, and version is higher than the software kit that BS has the latest edition of software version now;
Step 405, whether the multicast group that is judged as the software kit correspondence of BS selection is set up, if enter step 407, otherwise enter step 406; At this,, then can set up corresponding multicast group for it if software kit is transmission for the first time;
Step 406, OMC enters step 407 after setting up the multicast group of this software kit correspondence;
Step 407, OMC indication BS adds corresponding multicast group;
Step 408, BS adds the multicast group of software kit correspondence, and carries out the reception of software kit;
Step 409, after one time multicast transmission process finished, OMC waited for that BS responds;
Step 410, BS judges whether the complete software kit that receives, if then cover original software kit, and guidance system again, finishes the remote upgrade of this BS self, and notice OMC upgrade successfully, otherwise to OMC transmission software kit retransmission request message;
Step 411 after the BS that OMC upgrades success deletes from the multicast group of correspondence, is organized this multicast group to take turns and is broadcast, and retransmits software kit, upgrades successfully until all BS.
In above-mentioned processing procedure, if OMC has the software kit of new edition to add, this moment, this needed judge whether needs and can carry out corresponding software packet upgrade of existing BS according to the reporting information of the BS that has preserved, if, then enter step 407, software package executable is upgraded.
In step 410, BS notifies in the successful message of OMC upgrading and comprises the current software version sign.
Simultaneously, OMC also carries out control and management to the multicast group of software kit correspondence, as:
The free time of multicast group is set, and (the BS request multicast that does not add this multicast group) carried out deletion to this multicast group and handled when multicast group free time surpasses a predetermined threshold value;
The management of multicast group number is set, multicast group to the different editions of same software kit is provided with a default value, after the multicast group number of the different editions of same software kit reaches this default value, discharge the multicast group of the software kit correspondence of minimum version, provide address space to use for the software kit of latest edition.
Consider that simultaneously each controlled network element many times all adopts distributed structure/architecture, each controlled network element is a peer node, as the base station among LTE system and the B3G, therefore, realize issuing of software kit if only depend on OMC to set up multicast, the multinode network load sharing characteristic of not utilizing distributed structure/architecture fully and being had.
For the controlled network element of distributed structure/architecture, the present invention further is provided with following steps:
Do not have other equities in the complete controlled network element that receives software kit and the territory and the complete controlled network element that receives software kit set up point-to-point the connection, obtain software kit from the controlled network element that receives software kit equity and complete.
Be that BS is an example below with the controlled network element, the update method of multicast in conjunction with controlled network element point-to-point transmission software kit be described in detail that as shown in Figure 5, it comprises:
Step 501, BS adds network and energising starts;
Step 502, BS sends reporting information, and receives and preserve the reporting information of BS by OMC, and this reporting information comprises: hardware version information, NE type information, existing software version information;
Step 503, after the BS reporting information that OMC carries out a period of time is collected (reducing the appearance of fragmentary responding scene), OMC comprehensively adjudicates based on the reporting information of BS as far as possible, determine whether to be BS upgrade software bag, upgrade if desired, then enter step 504, otherwise return step 502;
Step 504, OMC is the software kit that BS selects suitable version, at this, OMC chooses from the set of the pairing software kit of the NE type of BS that hardware capabilities can support, and version is higher than the software kit that BS has the latest edition of software version now;
Step 505, whether the multicast group that is judged as the software kit correspondence of BS selection is set up, if enter step 507, otherwise enter step 506; At this,, then can set up corresponding multicast group for it if software kit is transmission for the first time;
Step 506, OMC enters step 507 after setting up the multicast group of this software kit correspondence;
Step 507, OMC indication BS adds corresponding multicast group;
Step 508, BS adds the multicast group of software kit correspondence, and carries out the reception of software kit;
Step 509, after one time multicast transmission process finished, OMC waited for that BS responds;
Step 510, BS judges whether the complete software kit that receives, if then cover original software kit, and guidance system again, finish the remote upgrade of this BS self, and notice OMC upgrade successfully, otherwise at the software kit request message of first type information of territory broadcast packet purse rope and version information, and the response of the BS of the complete receiving software bag in the wait territory;
Step 511, BS is select target BS from the BS of response, and sets up point-to-point the connection with this target BS, the receiving software bag, this agreement of setting up point-to-point connection can adopt FTP/TFTP;
Step 512, BS covers original software kit, and guidance system again, finishes the remote upgrade of this BS self, and notice OMC upgrades successfully.
Certainly, if in a period of time, without any the BS of response, when perhaps still successfully not receiving software kit, then the BS of this not complete receiving software bag can send the software kit retransmission request message to OMC, and OMC then can organize this multicast group to take turns and broadcast, and retransmits software kit.
BS notifies in the successful message of OMC upgrading and comprises the current software version sign.
In software upgrade process shown in Figure 5, the direct broadcast packages request message of the BS of not complete receiving software bag can certainly be controlled by OMC, below the OMC control mode is elaborated.
OMC obtains the reporting information that successfully upgrades BS, and OMC enables distributed dot to point mode to the BS of request renewal indication simultaneously, and at this moment, BS just directly begins the broadcast request process to other BS, and needn't wait for the multicast of OMC.
Certainly, when OMC can outnumber predetermined threshold value at the BS that success is upgraded, enable distributed dot to point mode, guarantee that the success of software kit is obtained to the BS indication that request is upgraded.
In the step 511, need select from the BS of response, its selection strategy can be selected according to the order that response message arrives.
In general, the software kit of controlled node is all bigger, in order further to improve the efficiency of transmission of upgrade software bag, in the specific embodiment of the inventive method software kit waiting for transmission is divided into a plurality of parts, and transmits after various piece is numbered (the sequence number sign that segmentation promptly is set).
After software kit was provided with segmentation, BS may miss the multicast content of some segmentation owing to adding reasons such as the multicast group is later, therefore, the change of the inventive method was described respectively in conjunction with dual mode at multicast and multicast and point-to-point transmission.
Set up the multicast group for OMC and carry out software kit transmission, and utilize the multicast group to take turns and broadcast, retransmit the mode (being flow process shown in Figure 4) that software kit is realized software upgrading, software kit is provided with segmentation after, in conjunction with shown in Figure 4, it relates generally to two steps:
Step 407 when OMC indication BS adds corresponding multicast group, also needs to indicate the segmentation number of the software kit of required reception in the multicast, so that BS judges whether to receive all segmentations;
Step 410, BS judges whether to receive integrated package according to this segmentation number, and other processes are as broad as long, do not repeat them here.
And for the upgrading mode (being flow process shown in Figure 5) of multicast and point-to-point transmission combination, involvement aspect is wider, is elaborated below in conjunction with Fig. 5.
Certainly, step 507 and step 510 are corresponding with step 407 and step 410, when OMC indication BS adds corresponding multicast group, also need to indicate the segmentation number of the software kit of required reception in the multicast, and BS judges whether to receive integrated package according to this segmentation number.
Simultaneously, in step 510, BS judge do not have complete receive software kit after, also should comprise sequence number sign of its disappearance segmentation in the software kit request message of broadcasting.
Certainly, can one carry the sequence number sign of all disappearance segmentations in the software kit request message, also can lack software kit request message of segmented construction each.
When a plurality of segmentation of a software kit of a BS disappearance, can comprise from the BS of response that a BS of all disappearance segmentations receives this disappearance segmentation, also can receive the disappearance segmentation respectively from the BS of a plurality of responses.
As 3 software kit segmentations of BS1 disappearance, and BS2 comprises this 3 software kit segmentations, and BS3, BS4 and BS5 have one of them software kit segmentation respectively, and BS2, BS3, BS4 and BS5 respond, at this moment, BS1 can select to receive all software kit segmentations from BS3, at this moment, only need set up a point-to-point connection, also can be respectively from BS3, BS4 and the segmentation of BS5 receiving software bag, this moment, speed was very fast, but need set up three point-to-point connections.
Consider that the software kit request message in this broadcasting is different from the software kit retransmission request message that BS points to OMC, can tackle discriminatively, can distinguish above-mentioned message in the following manner for ease of other BS in OMC and the territory:
Message name is distinguished by different message name;
The value of specific fields is composed different value to specific fields, and as the software kit request message of 1 expression broadcasting, and the software kit retransmission request message of OMC is pointed in 2 expressions;
Carry parameter, as not carrying the sequence number sign of software kit segmentation in the software kit retransmission request message of pointing to OMC, the software kit request message of broadcasting then comprises the sequence number sign of indicating segmentation.
After BS in the territory receives the software kit request message of broadcasting, need judge whether to respond, judge in the following manner this moment:
In having the software kit request message, during whole segmentation of indicated software kit, just respond;
In having the software kit request message, during indicated disappearance segmentation, just respond, but should carry the sequence number sign that self has segmentation in the response message.
BS sets up point-to-point the connection with the BS of response, receives the software kit segmentation of its disappearance from target BS.
And in step 512, also need data recombination is carried out in all software kit segmentations that receive, obtain final upgrade software bag, and use this software kit to upgrade.
Certainly, the software kit of above-mentioned controlled network element request can not be the upgrading that is used for self, also can be the upgrade software bag of its controlled network element that has under its command.
When method of the present invention is used for the software packet upgrade of other controlled network elements that controlled network element has under its command, its difference only be following some:
Comprise in the information that controlled network element (as BS) reports that it has the information of controlled network element (as RS) under its command;
The software kit that controlled network element obtains is not to be used for self upgrading, and it need send to the software kit that obtains other controlled network elements that have under its command and upgrade.
Its detailed process no longer is described in detail at this.
