Description

The method of access network node self-configuring and system thereof

Technical field

The present invention relates to the communications field, particularly a kind of method of access network node self-configuring and a kind of system that is used for the access network node self-configuring.

Background technology

Because universal mobile telecommunications system (UMTS) is to adopt the 3-G (Generation Three mobile communication system) of Wideband Code Division Multiple Access (WCDMA) (WCDMA) air interface technologies, so also the UMTS system is called the WCDMA communication system usually.The UMTS system has adopted and the similar structure of second generation mobile communication system, comprise Radio Access Network (Radio Access Network, RAN) and core network (Core Network, CN).Wherein RAN is used to handle all and wireless function associated, and CN handles that all voice calls are connected with data in the UMTS system, and the exchange of realization and external network and routing function.Wherein, CN from be divided in logic circuit commutative field (Circuit Switched Domain, CS) and packet-switched domain (Packet Switched Domain, PS).(User Equipment UE) has constituted whole UMTS system together for UTRAN, CN and subscriber equipment.

The UMTS system configuration as shown in Figure 1.As shown in Figure 1, the UMTS system can be divided into UE, UMTS Terrestrial radio access network (UTRAN), CN, gives the external network (external network) that is connected with the UMTS system among Fig. 1.Wherein, UTRAN comprises one or several RNS (RNS), and each RNS is made up of a radio network controller (RNC) and one or more base station (NodeB).It between UTRAN and the UE Uu interface.Interface between RNC and the CN is the Iu interface, and NodeB is connected by Iub interface with RNC.In UTRAN inside, interconnected by Iur between the RNC, Iur can connect or connect by transmission network and realizes by the direct physical between the RNC.RNC is used for distributing and is attached thereto with control or the Radio Resource of relevant NodeB.NodeB then finishes the conversion of the data flow between Iub interface and the Uu interface, also participates in a part of RRM simultaneously.The structure of UTRAN as shown in Figure 2.

NodeB is the base station of WCDMA system, comprises radio receiving-transmitting unit and Base-Band Processing parts.NodeB mainly finishes the processing of Uu interface physical layer protocol by the Iub interface and the RNC interconnection of standard.The major function of NodeB is spread spectrum, modulation, chnnel coding and despreading, demodulation, channel-decoding, also comprises the functions such as mutual conversion of baseband signal and radiofrequency signal.RNC is used to control the Radio Resource of UTRAN, mainly finishes functions such as connection foundation and disconnection, switching, the merging of grand diversity, RRM control.

The above network architecture is based on the 3GPP Rel6 framework of version in the past.Consider the competitiveness of future network, 3GPP is studying a kind of brand-new evolution network framework to satisfy the application demand of mobile network in 10 years futures even longer time, comprise the Long Term Evolution (LTE) of System Architecture Evolution (SAE) and Access Network, wherein the Access Network of evolution is called E-UTRAN.Because evolution network framework is a kind of brand-new network architecture, substantial variation all will take place in all nodes, function and the flow process of therefore existing framework.

Provided the packet core network framework of evolution among Fig. 3, comprise Mobility Management Entity (MobilityManagement Entity, MME), service SAE gateway (Serving SAE GW) and three logical functional entities of packet data network (PDN) SAE gateway (PDN SAE GW).Wherein, MME is responsible for the mobile management of chain of command, comprises the management of user's context and mobile status, and distributing user temporary identity sign etc. are corresponding to the control plane part of current GPRS/UMTS internal system Serving GPRS Support Node (SGSN); Serving SAE GW is responsible for initiating paging for downlink data under idle condition, and IP bearing parameter and the interior routing iinformation of network etc. are preserved in management, corresponding to the datum plane part of current GPRS/UMTS internal system SGSN and Gateway GPRS Support Node (GGSN); PDN SAE GW then serves as the user's face anchor point between different access systems.(Policy and Charging Rule Function PCRF) is used for policy control and determines and flow based charging control the "Policy and Charging Rules Function entity.(Home Subscriber Server HSS) is used for storing user subscription information to home network server.

Along with the flourish and broadband access network of Internet business and the extensive use of wireless network, 3GPP has begun the research work of base station from home (Home NodeB, Home NB).Home NB has with grand eNB identical functions or has the partial function of grand eNB, and Home NB allows the mobile subscriber hot spot coverage or outlying district to insert the mobile communications network of 3GPP by Home NB in family, office space etc.Macrocell high speed data service user has been shunted in the introducing of Home NB, so also solved the resource bottleneck problem of eating dishes without rice or wine in the wireless data service.

The SAE network architecture of the current Home of comprising NB has two kinds.A kind of is Home NB directly in public switched telephone network (PLMN), is the S1-MME interface of standard between Home NB and the MME promptly, and this framework as shown in Figure 4.Another kind is that Home NB is by inserting the PLMN network between the IAD (HNB GW) of PLMN network internal, this structure as shown in Figure 5, under this framework, interface between Home NB and the MME remains S 1-MME interface from application layer, but be divided into two sections in transport layer, one section is the transmission link between Home NB and the IAD, and one section is IAD and the internodal transmission link of MME.For fear of MME being introduced new function, the transport protocol stack between IAD and the MME is identical with S1-MME interface protocol stack under the common framework.Home NB can take different transmission meanss according to user's different IP networks access way with the transmission link between IAD, as ADSL (Asymmetric Digital Subscriber Line) (ADSL), cable (Cable) etc.

As Fig. 4, shown in Figure 5, there is X2 interface between Home NB and grand eNB.This X2 interface on the function with two grand eNB between X2 interface identical.

In order to reduce the workload that the network planning is optimized, reduce operator's operation cost, access network nodes such as grand eNB, HomeNB need have self-configuring, self-optimization function.The self-configuring function of access network node makes the node of new adding PLMN network obtain the operate as normal desired parameters automatically after powering on, and disposes relevant interface automatically, does not need artificial participation can realize the operate as normal of access network node.

Because Home NB is the new access network node that proposes, also there is not the self-configuring scheme of Home NB so far.List the self-configuring scheme with grand eNB below, as the prior art the most close with the present invention.

The present self-configuring self-optimizing flow process of grand eNB as shown in Figure 6.Referring to Fig. 6, the self-configuring flow process of grand eNB is as follows:

(A) basic foundation.This step is divided into following a few sub-steps:

A-1) detection of IP address configuration and operation management maintain (OAM) server.At first, grand eNB needs to set up a logic with the OAM server and is connected to finish authentication process, obtains simultaneously to add the needed information of network.In order to connect with the OAM server, grand eNB need know IP address, gateway address and the dns server address of oneself, and these addresses can realize obtaining automatically by DHCP mechanism, thereby can support self-configuring/self-optimizing.

A-2) grand eNB and internetwork mutual authentication.After grand eNB and OMA server are set up logic and are connected, grand eNB must and network between carry out mutual authentication process, avoid undelegated node to add network.

A-3) contact IAD.The IAD here is meant the MME node and the ServingSAE GW node of core net.This substep allows grand eNB to find automatically and gets in touch the MME node and the Serving SAE GW node of an optimum.

A-4) download eNB software and operational factor.Grand eNB downloads required software of eNB and operational factor automatically.If software version needs to upgrade, renewal process also will automatically perform.

(B) initial wireless configuration.This stage comprises configuration, and all need set up the required relevant configured parameter of wireless connections in grand eNB.These configuration parameters comprise, as the abutting subdistrict list of planning in advance, pilot power, antenna tilt etc.Step (B) comprises following substep:

B-1) set up in abutting connection with tabulation.Can set up by network optimization network planning instrument in abutting connection with tabulation, or by utilizing geography information, giving birth in abutting connection with tabulation from movable property by the measurement report of collecting UE.

B-2) the relevant parameter configuration of covering/capacity.Wherein, relevant with covering/capacity wireless parameter is set to only value automatically.

(C) optimization and adaptive.Step (C) comprises following substep:

C-1) optimize in abutting connection with tabulation.Grand eNB according to the measurement of UE when the gravity treatment of sub-district to being optimized in abutting connection with tabulation.

C-2) covering/volume controlled.Grand eNB realizes according to the Automatic Optimal process of node ruuning situation to the relevant wireless parameter of covering/capacity at this substep.

In addition, the self-configuring step of the S1-MME interface between grand eNB and MME is as follows:

The first step: prerequisite.The eNB first-selection will obtain IP address and the IP address of all MME of opposite end and the parameter that other S1-MME self-configuring needs of oneself.

Second step: stream control transmission protocol (sctp) initialization.ENB sends the SCTP association request of setting up to each with the MME that has S1-MME interface that controls oneself.After this step finished, eNB and all and its existed the SCTP association between the MME of S1-MME interface to set up.

The 3rd step: application layer initialization.ENB and MME are by the configuration parameter of the S1-MME interface interactive application layer set up.Concrete application layer message comprises following two parts: 1) eNB offers the information of MME, tabulates as the tracking area (TA) of eNB sign (ID), support etc.; 2) MME offers the information of eNB, as MME ID, PLMN ID etc.

After above-mentioned three steps, the dynamic-configuration process of S1-MME interface has just been finished, and at this moment, the interface of S1-MME just can think to be in normal operating condition.

Above-mentioned prior art has only provided the roughly description of grand eNB self-configuring, does not propose wherein each step and specifically how to operate, and for example: how the IP address of eNB obtains, how to get in touch GW, how to dispose in abutting connection with tabulation or the like.And such scheme does not consider how the S1-MME interface under the Home NB scene realizes self-configuring, and therefore, prior art can not satisfy the demand that Home NB realizes dynamic self-configuring yet.In addition, definite process of the self-configuring parameter of Home NB and grand eNB are also different.The self-configuring parameter of grand eNB is the result of the network planning, and Home NB is because its characteristic, and the process that the self-configuring parameter of Home NB may exist and network management system (OMC) is repeatedly consulted is just definite.

OMC is described below in the self-configuring process to the management of Home NB.Mainly be divided into software upgrading and download management in embodiments of the present invention, at network operation configuration parameter management (the automatic management of configuration parameter), equipment operation parameter management, reach special management etc. unusually.

The 9th embodiment: software upgrading and download management.Here be divided into preceding (Pre-operational) stage of operation and operation (operational) stage.

1) in the Pre-operational stage

When Home NB uses first or just powered on, at first to obtain local IP address.The acquisition of IP address has various ways, for example obtains Intranet IP, obtains public network IP, obtains special I P etc. by the IPsec technology from OMC from operator's Dynamic Host Configuration Protocol server at local Dynamic Host Configuration Protocol server.

Home NB can initiate to connect the request of foundation to OMS by the OMC domain name or the address that prestore then, and adopts suitable technique that both sides' identity is authenticated.

If authentication success, Home NB comprise product type, device id, board type, hardware version, software version etc. with reporting equipment information.OMC will analyze software and hardware model and the version information of Home NB, confirm whether Home NB needs to download or upgrade software.If desired, for example the software and hardware model of HomeNB and version information are not up-to-date, and then OMC/SON Server will send required software to HomeNB.Home NB move or upgrade software after reset, be connected with OMC once more.

2) the Operational stage

Home NB might need update software in running, two kinds of situations are arranged this moment: a kind of Home of being NB initiatively obtains the recent software version information to OMC/SON Server, as finding to have latest edition, then downloads or point out the back to download; Another kind is that OMC need carry out unified upgrading to Home NB of the same type in the network, sends recent software by OMC/SON Server to them, and perhaps the prompting back is downloaded by Home NB.

After the software upgrading, Home NB will reset, and original S1-MME is connected with X2 and will rebuilds.

The tenth embodiment: manage at the network operation configuration parameter.Here also be divided into Pre-operational stage and Operational stage.

1) the Pre-operational stage

After Home NB powers on operating software, can obtain at the network operation configuration parameter from OMC/SON Server usually, this moment, Home NB can initiate to obtain flow process at the net configuration parameter, and begin to set up S1, X2 after the Home NB configuration and connect, and normal operation.

In order to reduce dependence to OMC/SON Server, improve self-configuring efficient, Home NB also can dispose relevant parameter automatically according to previous configuration parameter or according to measurement result, the operation application is sent to OMC/SON Server in the configuration back, after obtaining OMC/SON Server affirmation, beginning is at network operation.

2) the Operational stage

When Home NB behind network operation, Home NB and OMC/SON Server may be according to some needs, change part configuration parameter.Can initiate at net configuration parameter modification process this moment, revises configuration parameter.

If adopt the auto configuration mode configuration before the Home NB operation, OMC might not understand actual parameter configuration, if know about the demand of detailed configuration parameter this moment, OMC can initiate to obtain flow process at the net configuration parameter, asks for the parameter configuration of Home NB reality.

In order to guarantee the consistency of user side Home NB and the OMC of operator end configuration parameter, can also initiate as required in network operation parameter synchronization flow process, avoid because the inconsistent operation troubles that causes of parameter.

Describe to revise the configuration parameter flow process below respectively, obtain flow process at the net configuration parameter, in network operation parameter synchronization flow process.

Example 1: at net configuration parameter modification process.Home NB and OMC/SON Server all can initiate at net configuration parameter modification process, and this flow process can be divided into to be revised the opposite end parameter and revise two kinds of situations of local parameter.

Figure 17 shows that Home NB revises local situation.As shown in figure 17, this flow process may further comprise the steps:

Step 1201, Home NB is according to oneself measurement and other customization needs, and the definite parameter that need revise is initiated to revise the request of local configuration parameter to OMC/SON Server.

Step 1202 is examined after OMC/SON Server receives to step 1203, according to result of calculation and other strategy of self-optimizing, confirms the validity of revising.If can revise, OMC/SONServer can return acceptance (accept) and confirm.

Step 1204 is to step 1206, and Home NB revises local configuration parameter, and returns success the modification affirmation to OMC/SONServer, and OMC/SON Server revises corresponding configuration parameters after receiving affirmation again.

Figure 18 shows that Home NB revises local another kind of situation, with different among Figure 17 be that Home NB sends to OMC/SON Server with measurement result here, determines whether change by OMC/SON Server.As shown in figure 18, this flow process may further comprise the steps:

Step 1301, Home NB need mail to OMC/SONServer with oneself measurement result and other customization.

Step 1302 is to step 1303, and OMC/SON Server determines whether to change configuration parameter on the Home NB according to measurement result, if desired, then new configuration parameter is issued Home NB.

Step 1304 is to step 1305, and Home NB revises local parameter, and returns success affirmation to OMC/SON Server.

Step 1306, after the modification that OMC/SON Server obtains Home NB was successfully confirmed, OMC/SON Server revised corresponding configuration parameters again.

Figure 19 shows that OMC/SON Server revises the situation of opposite end Home NB parameter.As shown in figure 19, this flow process may further comprise the steps:

Step 1401, OMC/SON Server initiates to revise the configuration parameter request according to result of calculation and other strategy of self-optimizing to Home NB.

Step 1402 is to step 1404, and Home NB perhaps need not examine after examining through necessity, revises the configuration parameter of self, returns success simultaneously and confirms to give OMC/SON Server.

Step 1405, OMC/SON Server revises corresponding configuration parameters subsequently.

Above-mentionedly not being only applicable to the needs of some parameter of network terminal correction Home NB at net configuration parameter modification process, also can be because Home NB moves to reposition or detects scene such as new environment and cause the adjustment of some parameter.

Example 2: at net configuration parameter version synchronization mechanism.OMC/SON Server and Home NB all can transmit a request to the opposite end and extract up-to-date configuration data version and modification time information, check then, if take place inconsistently, then initiate at net configuration parameter modification process.As shown in figure 20, this flow process may further comprise the steps:

Step 1501, OMC/SON Server sends parameter version and modification time request to Home NB.

Step 1502, Home NB configuration data version and the modification time that this locality is up-to-date sends to OMC/SON Server.

Step 1503 is to step 1504, and OMC/SON Server checks each versions of data and modification time, need to judge whether to upgrade, and upgrades if desired, and then OMC/SON Server initiates modification configuration parameter flow process as shown in figure 19.

Shown in addition, if the request that Home NB at first sends, then flow process was as the step 1501 among Figure 19 ' to step 1505 ', different was, in step 1505 ' in, Home NB initiates is modification configuration parameter flow process shown in Figure 17,18.

Though change is at the net configuration parameter, OMC/SON Server and Home NB generally can notify the other side to revise simultaneously, but still have the parameter difference that some abnormal conditions cause both sides, and the synchronization mechanism of configuration parameter can effectively reduce the generation of this situation.Synchronous mode and frequency can be formulated as required.

Example 3: obtain flow process at the net configuration parameter.This flow process Home NB and OMC/SON Server all can initiate.

Obtain flow process as what Figure 21 and Figure 22 had provided that Home NB initiates at the net configuration parameter.Flow process as shown in figure 21 comprises:

Step 1601, Home NB sends to OMC/SON Server and obtains message, does not carry information such as configuration parameter version and modification time in the message.

Step 1602, if there is not the information of parameter version and modification time, then OMC/SON Server configuration parameter directly that will preserve or newly-generated this Home NB is issued Home NB.

Step 1603 is returned acknowledge message after Home NB receives;

Flow process as shown in figure 22 comprises:

Step 1701, Home NB sends to OMC/SON Server and obtains message, carries information such as configuration parameter version and modification time in the message.

Step 1702, OMC/SON Server will judge whether parameter is effective, expired or incomplete, upgrade if desired, promptly invalid, expired or incomplete, OMC/SON Server can be handed down to Home NB with this HomeNB effective configuration parameter; If parameter effectively and fully, then OMC/SONServer can return and not revise (No change) message, Home NB can look existing configuration parameter and be the result.

Step 1703, Home NB returns acknowledge message after successfully receiving/judging.

Shown in Figure 23 is, and OMC/SON Server initiates obtains flow process at the net configuration parameter.When OMC/SON Server carries out self-optimizing calculating,, can initiate to obtain flow process at the net configuration parameter if want to understand the actual configuration parameter of certain Home NB.This flow process is as follows:

Step 1801, OMC/SON Server initiates to obtain configuration parameter and obtains request.

Step 1802, Home NB generates the message of configuration parameter, and returns OMC/SON Server.

Step 1803, OMC/SON Server returns acknowledge message after successfully receiving.

One of application scenarios is, not directly configuration and operation automatically after Home NB powers on by OMC/SON Server, the situation that powers on again behind the electricity under the Home NB for example, but OMC/SON Server has not contained the configuration parameter of this Home NB, for computation optimization, OMC/SON Server must obtain its detailed configuration parameter.

Example 4: load and available information are submitted flow process to.This flow process occurs between the OMC/SON Server of the OMC of MME or MME and Home NB.

As shown in figure 24, this flow process comprises:

Step 1901, the OMC/SON Server of Home NB can initiatively initiate to apply for the modification local parameter request of MME load and available information, to obtain the up-to-date operation conditions of MME.

Step 1902, the OMC of MME or MME can issue the OMC/SON Server of Home NB with up-to-date load and available information according to the OMC/SONServer of Home NB, perhaps directly regularly up-to-date load and available information is issued the OMC/SON Server of Home NB and be need not step 1901.

Step 1903 is to step 1904, and OMC determines whether to initiate at net configuration parameter modification process by self-optimizing calculating according to these information and out of Memory, if desired, then initiates to revise the flow process of configuration parameter.

The 11 embodiment: equipment operation parameter management.Here be meant equipment operation parameter management in the Operational stage.

Home NB also needs the equipment operation parameter except software with the network operation configuration parameter, such as hardware buffer district size, RF relative parameters setting, maximum access customer number etc.Though generally have default setting when equipment dispatches from the factory and solidify and advance Home NB, seldom need to adjust, but needs for the self-optimizing adjustment, OMC/SON Server can do function restriction or function permission setting to some Home NB, at this moment OMC can initiate at net configuration parameter modification process, by the equipment operation parameter that this flow process transmission need be revised, Home NB changes after receiving, and returns acknowledge message.The process here is similar to the tenth embodiment, repeats no more.

The 12 embodiment: reach special management unusually.Main pointer is to the needs of unusual or special management occur at the Home of network operation NB, by the exception management flow process of OMC/SON Server initiation.This series flow process mainly comprise onlinely reset, temporary transient flow processs such as isolation, Force Deletion.

Example 1: online resetting comprises the online Home of resetting NB equipment, rebuilds S1 or X2 connection etc.OMC/SON Server both can directly reset to unusual Home NB for the needs of management, and certain bar that also can only rebuild Home NB connects, and reduces the influence to customer service.

Example 2: the temporary transient isolation.OMC/SON Server is for the needs of management, and S1, the X2 that can delete certain Home NB connect temporarily, can also close radio-frequency module alternatively, but the configuration parameter of sweep equipment in OMC/SON Server do not identify with necessary.OMC/SON Server may initiate the configurations such as S1, X2 connection to this Home NB subsequently again, and Home NB recovers normal operation.

Example 3: Force Deletion.OMC/SON Server can play except that some Home NB for the needs of management and restrict access.S1, X2 that this moment, OMC/SON Server deleted Home NB with start flow connect, and close radio-frequency module alternatively, and the configuration parameter of sweep equipment in OMC/SON Server, and during equipment/user ID was piped off, equipment was forced to off line.
