Embodiment
Below in conjunction with accompanying drawing the embodiment of the embodiment of the invention is done further and to be elaborated.
See also Fig. 1, for realizing the schematic flow sheet of the method that network is found in the embodiment of the invention one.This method is applied to carry out the network equipment (hereinafter to be referred as access device) that network is found, access device can include but not limited to AP, switch or router etc.In the present embodiment, this method comprises the steps:
S101, access device send the request of access to the network element selection functional entity (Selector) that is used to access device configuration transmission parameter.
Inserting the region control strategy according to operator divides, the on-position of access device can be in territory, local (being ownership place), also can be in territory, non-local (i.e. visit ground), access device sends to insert to Selector and asks to comprise following three kinds of situations like this:
(1) when the Selector address in the built-in input field of access device (comprising territory, local and territory, non-local), the access device directly Selector in input field sends the request of access.
(2) the Selector address in territory, the built-in local of access device, and when inserting from territory, non-local, if the whole network has only unique Selector, be that Selector in the territory, local and the Selector in the territory, non-local are arranged in same equipment, perhaps the Selector in Selector in the territory, local and the territory, non-local forms distributed system, but for access device, have only a visible Selector, then access device directly sends the request of access to this visible Selector.
(3) the Selector address in territory, the built-in local of access device, and when inserting from territory, non-local, access device sends query requests to a Selector (being the Selector in the territory, local); The one Selector returns the address of the 2nd Selector (being the Selector in the territory, non-local), and access device sends the request of access to the 2nd Selector.
Can comprise the characteristic information of access device in the above-mentioned access request, characteristic information can include but not limited to: the information of on-position, state, sign ID, version, production firm, affiliated territory, nearby device, service feature, service quality, load and/or medium tenability.
S102, Selector are according to the corresponding network element of Information Selection that inserts request and related network elements.
Related network elements refers to an access equipment in this step may need the device that connects behind access network, can include but not limited to self-configuring server (Auto-Configuration Server, ACS), security gateway (Security Gateway, SeGW), IAD, network planning server (Planning Server), software server (Software Server) and/or relevant auxiliary back-up system and background service system etc., in embodiments of the present invention, access device, each device in Selector and the related network elements, can only refer to single hardware device, also can comprise the group that two or more single hardware devices are formed.
Concrete, according to the information that inserts request and related network elements, select network element according to following each selection strategy or its combined strategy:
(1) load strategy, promptly Selector selects the less relatively entity of load, and as the network element that connects, this entity can provide good service for the access of access device.
Application load strategy, Selector select present load to satisfy the related network elements of the request of access at first according to the present load of this network element of information acquisition of related network elements then.Wherein, Selector selects present load to satisfy when inserting the related network elements of asking and can adopt load balancing algorithm or operator's load sharing policy:
If the employing load balancing algorithm, then Selector is that present load related network elements from small to large distributes weight from big to small respectively; With the weight size is the height of priority, selects and the corresponding network element of access request.
If adopt operator's load sharing policy, then Selector handles the related network elements information (mainly being the real time information relevant with dynamic-configuration) of collecting, and according to inserting request, dynamically carries out load sharing policy, is met the related network elements of the request of access.
(2) on-position strategy is promptly selected to insert regional entity near access device, as the network element that connects.
Because the related network elements that access device inserts may be deployed in each zone of operator's division, therefore selects network element according to nearby principle, can avoid the circuitous and time delay of route.
Application on-position strategy, Selector are according to the position of this network element of information acquisition of related network elements, and then according to nearby principle, chosen position satisfies the related network elements of the request of access.
(3) quality of service policy is promptly selected network element in conjunction with access device to the quality of service requirement (for example bandwidth, time delay etc.) of certain class business.
Application service quality strategy, Selector according to the service quality and the close degree that the request of access requires of related network elements, assign weight then according to the service quality of this network element of information acquisition of related network elements, and close degree is high more, and weight is big more; Be the height of priority again with the weight size, select and the corresponding network element of access request.
(4) degree of correlation strategy is promptly selected and the higher entity of the access device degree of correlation, as the network element that connects.The degree of correlation can include but not limited to: the configuration degree of correlation or the territory degree of correlation.
Wherein, the configuration degree of correlation is meant: access device exists version (comprising software and hardware) and manufacturer's difference, these differences can embody by characteristic information, and Selector can select related network elements (for example network element device or backend services system) that access device is configured according to characteristic information;
The territory degree of correlation is meant: satisfy network topology and mobile management requirement, to being positioned at the related network elements of same domain with access device, when selecting, giving respective weights considers, for example: when UE inserts access device or grand network, because UE moves, when switching to macro base station from access device or when opposite, might there be the switching of striding service general grouping service wireless support node SGSN or mobile switching centre (MSC), cause the busy and resource consumption of network like this, if can when access device realizes that network is found, just consider this factor, then might avoid striding following UE and move SGSN-spanning or the MSC switching that brings, reduce resource consumption.So, when the access device access network is initial, should consider the IAD (AG) of selecting the same core network element node of adjacent macro base station with access device to link to each other, during selection, give respective weights and consider.
Use degree of correlation strategy, Selector is the information and the degree of correlation that inserts characteristic information in the request of related network elements at first relatively; Assign weight according to the degree of correlation then, the degree of correlation is high more, and weight is big more; Be the height of priority again with the weight size, select and the corresponding network element of access request.
The process of carrying out the network element selection in conjunction with various strategies can specifically be divided into two parts content, that is: the degree of correlation of characteristic information in the information of more described related network elements and the described access request; According to the weight of the described degree of correlation, select and the corresponding network element of access request.
Further, according to the weight of the described degree of correlation, select can adopt following method with the corresponding network element of access request:
(1) information of getting rid of related network elements does not match in the described access request to the network element of service feature and medium tenability; The comprehensive weight of the satisfaction of the satisfaction of the matching degree of on-position, service quality and version in the information of the related network elements after calculating is got rid of; With the size of described comprehensive weight height, select and insert the corresponding network element of request as priority.
(2) information of getting rid of related network elements does not match in the described access request to the network element of service feature and medium tenability; Select present load to satisfy the related network elements of described access request the network element after getting rid of.
(3) information of getting rid of related network elements does not match in the described access request to the network element of service feature and medium tenability; According to load balancing algorithm or operator's load sharing policy, select the network element of present load minimum the network element after getting rid of.
S103, selection result is back to access device, then access device inserts related network elements according to selection result.
When the network element that Selector selects in S102 was the single network entity, the selection result of returning in this step was the information of this network element; When the network element of selecting in S102 as Selector was a plurality of network entity, the selection result of returning in this step was the tabulation that the information of a plurality of network elements forms.
In the present embodiment, when not having the information of pre-configured related network elements on the Selector, Selector can carry out following S102 ' earlier before carrying out S102.
S102 ', Selector obtain the information of related network elements.Concrete, Selector can realize obtaining the information of related network elements by passive reception or active collection.
The information of the passive reception related network elements of Selector can comprise following three kinds of situations:
(1) increase information gathering mechanism on Selector, Selector regularly or irregularly receives the information from related network elements.
(2) Selector is furnished with on each acquisition target (being related network elements) and gathers agency (Agent), has the information subscribing relation between Selector and each Agent, receives the related network elements information of Agent according to the acquisition plan feedback; Wherein, acquisition plan can be specified or other management systems settings by Selector; Acquisition plan can include but not limited to: collection period, collection content, collection report cycle, data report mode, data to report address and/or data acquisition strategy.
(3) Selector increase and the NE management entity between interface, thereby obtain the information of related network elements, and need not to gather voluntarily these information.The NE management entity is used to manage related network elements; The NE management entity can include but not limited to webmaster or management server, adopts the mode of the information of this kind collection related network elements, can reuse the function of existing NE management entity.
Selector in this step can also initiatively gather the information of related network elements.For example, Selector can monitor network state when changing, and sends query requests to the NE management entity.The NE management entity is according to described query requests, to Selector feedback related network elements information.It can be that new network element access network is arranged that the network state here changes, and also can be the state variation of related network elements, and for example the service quality of related network elements, service feature, version, medium tenability and/or position change;
Adopt the technical scheme of present embodiment, for access device, by Selector the information of related network elements is collected, and according to the access request of the network equipment and the corresponding network element of Information Selection of related network elements, thereby can realize adaptive network discovery according to the variable condition of network element.
The method that the embodiment of the invention two is found the realization network among the embodiment one is applied on the AP.After AP starts, owing to do not know the situation of institute's access network, thereby need the process that a discovery and foundation and core net access related network elements connect, this process is referred to as network discovery process.When inserting with AP below, related network elements comprises that AP IAD (AG), ACS and SeGW are example, and network discovery and access procedure are described:
See also Fig. 2, AP, related network elements all occur with group's form among the figure, and all may there be multiple choices in expression respectively.Present embodiment comprises the steps:
At first be connected on the entity (Selector) of being responsible for transmission parameter configuration (being the network element selection function) after step 1, AP start, report the characteristic information of AP to it.
Step 3, Selector in conjunction with carrier policy, select corresponding network element after receiving that AP inserts the characteristic information of asking and reporting, and selection result returned to AP, this selection result is used to indicate access device to insert selected network element, such as, relevant parameters such as the address of network element, state.
Step 4, AP initiate request according to the selection result that receives to selected network element, and then finish follow-up automatic layoutprocedure to AP.
Present embodiment can be realized the network discovery of AP.Be after AP starts, can correctly connect the network element relevant, obtain corresponding radio resource, finish the initialized course of work with access from network is known nothing.Because Selector can dynamically obtain the information of relevant access network element, so AP can realize adaptive network discovery according to the variation of relevant access network element state when inserting.
1) address of built-in Selector entity or name in AP, AP is resolved this address or name by the public network service after starting, and obtains the actual address that AP can visit this Selector that obtains.
2) address of built-in security gateway in AP, with security gateway reciprocal process in acquire the Selector address.
3) AP finds DHCP (DHCP) server earlier, is the Selector that AP finds first to connect by Dynamic Host Configuration Protocol server.
4) the Selector address that will connect by manual configuration AP.
Wherein, AP can be kept at Selector address or name in the class SIM card or solidify in AP hardware.
By above method, AP can find corresponding Selector, thereby can further carry out follow-up network discovery process when start.
The information gathering mechanism that step 2 in the foregoing description two can adopt the embodiment of the invention three to provide, Selector can be regularly or the information of collecting each network element relevant with the AP access aperiodically, make it when receiving that AP starts request, carry out selection strategy according to collected net element information.
Embodiment three as shown in Figure 3, Selector is as information collector, all is distributed with one and gathers agency (Agent) on each acquisition target.
There is information subscribing relation (Info Subscription) between Selector and each Agent, this subscribing relationship is set by Selector or other management system, each Agent will carry out by the acquisition plan of setting, and the setting of acquisition plan includes but not limited to: 1) collection period; 2) gather content; 3) gather report cycle; 4) data report mode; 5) data report address etc.
The method that step 2 in the foregoing description two can also adopt the embodiment of the invention four to provide, that is: the interface between the newly-increased and webmaster (or other management server) of Selector, and obtain with AP by newly-increased interface and to insert relevant net element information, gather these information voluntarily and need not Selector, so also can reuse the existing network Functions of Management System.Embodiment four as shown in Figure 4, the Itf-Query interface that promptly to be Selector carry out the network element inquiry to CN nodes OAM (the core network element network operation administers and maintains) system among the figure.In the present embodiment, CN nodes OAM system is the network management system of all network elements of higher management net side, and this system can know that being included as AP inserts and the AG of increase the instant messages of network elements such as SeGW.Selector is (acquisition target is gathered content etc.) according to actual needs, initiates query requests by the Itf-Query interface to OAM, obtains the information of related network elements by the feedback information that receives OAM.It is similar to gather relevant setting and embodiment three, repeats no more.
