The present invention relates to evolvement mobile network, especially relate to and set up ICR (Inter Cell Radio Resource Management in a kind of evolvement mobile network, minizone RRM, minizone RRM) method that concerns between collection initiator, informant, information preserver and the ICR function effector.
Background technology
UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) be to adopt WCDMA (Wideband Code Division Multiple Access, the Wideband Code Division Multiple Access (WCDMA) access) 3-G (Generation Three mobile communication system) of air interface technologies also calls the WCDMA communication system to the UMTS system usually.The UMTS system has adopted and the similar structure of second generation mobile communication system, comprises RAN (Radio Access Network, Radio Access Network) and CN (Core Network, core network).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.CN is from being divided into CS (Circuit SwitchedDomain, circuit commutative field) and PS (Packet Switched Domain, packet-switched domain) in logic.Fig. 1 is a UMTS system configuration schematic diagram, and as shown in Figure 1, UTRAN (UMTS TerritorialRadio Access Network, UMTS Terrestrial radio access network), CN and UE (UserEquipment, subscriber equipment) have constituted whole UMTS system together.
UTRAN, it comprises one or several RNS (Radio Network Subsystem, RNS).Fig. 2 is the UTRAN schematic network structure, and as shown in Figure 2, a RNS is made up of a RNC (Radio Network Controller, radio network controller) and one or more NodeB (base station).Wherein, the interface between RNC and the CN is the Iu interface; NodeB is connected by Iub interface with RNC; In UTRAN inside, connect by Iur between the RNC, Iur connects that the direct physical that refers between the RNC connects or the connection by transmission network.
Wherein, 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; NodeB is the base station of WCDMA system, comprises radio receiving-transmitting unit and Base-Band Processing parts, and its major function 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; NodeB finishes the processing of Uu interface physical layer protocol simultaneously by the Iub interface and the RNC interconnection of standard.
The above-mentioned network architecture is based on the 3GPP Re16 framework of version in the past, in current 3GPP network, to O﹠amp; M (Operation and Maintenance, operation and maintenance) is defined as:
Fig. 3 is O﹠amp in the prior art; The RNS structural representation of M interface, as shown in Figure 3, direct and O﹠amp on NodeB; The part that the execution of M is relevant, called after: Implementation specificO﹠amp; M; Another part is relevant with one group of signaling, and this signaling is finished by RNC control, and the management of the Radio Resource of carrying out by Node B, called after: Logical O﹠amp; M.
For Implementation specific O﹠amp; M, its Node B administration module direct and OMC (Operation andmaintenance Center, network management platform) connects, and carries out correlation function;
For Logical O﹠amp; M, its essence is one group of signaling as long as refer to the radio configuration function, relevant with the control of logical resource, this resource is controlled by RNC, comprises channel, sub-district etc., and physically realize the O﹠amp on the Node B by Node B; The program of M will influence the logical resource by RNC control, so Node B need carry out information interaction with regard to these resource informations with RNC, and this process is undertaken by Iub interface.
By existing 3GPP agreement as can be known, Logical O﹠amp; M is the part of NBAP protocol signaling in current UMTS system, in 3GPP TS25.433V6.8.0 (2005-12) those NBAP flow processs and signaling has been done concrete regulation.
At present, 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, comprises the Long Term Evolution (LTE) of System Architecture Evolution (SAE) and Access Network.The target of network evolution is to be desirable to provide a kind of low time delay, high data rate, high power system capacity and covering, low cost, complete IP-based network.Owing to be 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.
In the evolvement mobile network, in RRM (Radio Resource Management RRM), increased sub-function items a: ICR (inter Cell RRM, minizone RRM, minizone RRM).
The minizone wireless resource management information generally comprises the load information of sub-district and the interfere information of sub-district, abbreviates ICR information as; But ICR information is not limited to above 2 kinds of information, needs only the information that the ICR controlled function is worked, and can be called ICR information.At ICR information, evolvement mobile network has proposed ICR collection initiator, informant, information preserver and ICR function effector's notion.
The evolution mobile system uses the OFDMA technology, and it provides technical foundation for the carrier wave of minizone or the dynamic adjustment of sub-carrier resources, can be as certain sub-district according to the load information of neighbor cell on every side, and resource is leased in peripherad sub-district; Perhaps the interfere information of neighbor cell around certain sub-district basis is adjusted the aerial angle of oneself etc.; This function specifically comprises the management of minizone load management and presence of intercell interference, and we are referred to as the ICR controlled function, and possess the functional module of this control ability, and we are referred to as ICR function effector; As its name suggests, the functional module that can initiate ICR information gathering is referred to as the ICR collection initiator; The functional module or the node of ICR information are provided, are referred to as the ICR informant; And be responsible for preserving the functional module or the node of ICR information, be referred to as ICR information preserver.
At present, LTE is to RRM information, ICR information and Logical O﹠amp; M has proposed some new demands, needs to consider Logical O﹠amp as mentioning under the central controlled mode of RRM at the chapters and sections 6.12.4CentralisedHandling of 3GPP TR R3.018V0.1.0 (2006-01) of certain RRM Functions; The realization of M;
At chapters and sections 6.12.2.5Inter-cellRRM (interference management ﹠amp; Load management) mentions in (ICR):, need inter-cellRRM because power disturbance and cell load are unequal; Inter-CellRRM may be Logical O﹠amp; The part of M; And because the moving and dynamic property that data rate changes of user, dynamic I nter-CellRRM also be need or the like situation.
Mention for UMTSR99-Re1-g in chapters and sections 6.12.2.6Radio Configuration (RC) lining, OMC provides resource and parameter information to RNC, RNC is handed down to Node B again, resource and parameter information comprise that the sub-district sets up parameter, system message etc., these overall radio configuration allow operator that overall situation strategy is provided or adopt the strategy of more real-time RRM algorithm, are used for controlling the capacity and the coverage of sub-district, adjust network to adapt to the network traffics demand.
In the existing UMTS system, the supplier of RRM information (Node B or sub-district) is the corresponding RNC's of default report, and for evolvement mobile network, the ICR information relevant with certain sub-district, probably will be to a plurality of ICR information preserver reports, as may being one or more RRMserver (RRM server), or adjacent a plurality of eNodeB (NodeB of evolution), or other has Logical O﹠amp; The separate nodes of M function, flow process and signaling in the existing UMTS system obviously can not satisfy the demand.

Embodiment
Among the present invention, ICR information solution method in a kind of evolvement mobile network is provided, set up in the process in the sub-district or cell re-configuration is put in the process, module with data configuration function, be called for short the data configuration functional module, it initiates signaling process to eNodeB, sets up the relation between following ICR collection initiator, informant, information preserver and the ICR function effector; Module with data configuration function comprises OMC and radio-resource-configuration control module etc., and the radio-resource-configuration control module can combine with OMC, and is perhaps placed apart in eNodeB or certain separate nodes with OMC.
At the signaling between data configuration functional module and the eNodeB, there are two kinds of signalings because of the difference of the interface type between its two again, as described below:
With OMC is example, Fig. 4 is OMC and an eNodeB connection diagram in the evolvement mobile network, as previously mentioned, in the evolvement mobile network, substantial variation all will take place in all nodes, function and the flow process of existing network framework, NodeB after the evolution, be referred to as eNodeB, its with OMC between changed in the UMTS system the indirect structure that is connected by RNC, adopted a kind of mode of new logic interfacing to connect, and, be broadly divided into three kinds of situations for the logic interfacing between OMC and the eNodeB, as described below:
There is intermediate node E-LogicalO﹠amp in interface one, as shown in Figure 5 between OMC and the eNodeB; M is OMC-E-Logical O﹠amp; M-eNodeB three-layer network structure, E-Logical O﹠amp; M is used for representing the Logical O﹠amp of evolution; M, this intermediate node realize the Node B Logical O﹠amp on the RNC in the similar present UMTS system; The M function is reequiped the configuration data that OMC issues, and makes it to become the NBAP signaling that is similar in the present UMTS system, and be referred to as the NBAP signaling of evolution, and carry out the related procedure of such signaling, wherein, eNodeB and intermediate node E-LogicalO﹠amp; Interface definition between the M is the Z2 interface, intermediate node E-Logical O﹠amp; Logical O﹠amp among M and the OMC; Interface definition between the M counterpart is the Z1 interface; This Z2 interface class is similar to the Iub interface in the present UMTS system, and what transmit by this interface is the NBAP signaling of evolution, and this Z1 interface is general network management interface, the signaling that is based on general network management interface that transmits by this interface;
Interface two, as shown in Figure 6, intermediate node E-Logical O﹠amp; M migrates to the eNodeB place, is OMC-eNodeB two-tier network structure, E-Logical O﹠amp; M can be understood as the functional module that is built in eNodeB, OMC directly and eNodeB have interface, its interface type is general network management interface, by this interface, OMC directly is handed down to eNodeB with configuration data, the signaling that is based on general network management interface of its transmission;
Interface three, as shown in Figure 7, intermediate node E-Logical O﹠amp; M migrates to the OMC place, is OMC-eNodeB two-tier network structure, E-Logical O﹠amp; M and OMC integrate, and directly there is interface in OMC with eNodeB, and the interface between OMC and the eNodeB is general network management interface at this moment, and by this interface, OMC directly is handed down to eNodeB with configuration data, the signaling that is based on general network management interface of its transmission;
In sum, because intermediate node E-Logical O﹠amp; M present position difference can form above-mentioned two kinds of different interface types, and for these two kinds of different interface types, wherein the signaling of Chuan Songing comprises two kinds: based on the signaling of general network management interface or the NBAP signaling of evolution;
And for the relation between ICR collection initiator, informant, information preserver and the ICR function effector, also can distinguish to some extent because of the difference of functional entity in the evolvement mobile network, specific as follows:
As shown in Figure 4, in the evolvement mobile network, RRM SERVER is the functional entity that can select, it is represented by dotted lines in the drawings, according to the existence of RRM SERVER in the evolvement mobile network whether, and the difference of when RRM SERVER exists, carrying out function, the relation between ICR collection initiator, informant, information preserver and the ICR function effector can be described below:
(1) when not having RRM SERVER in the evolvement mobile network:
For ICR function effector, there are three kinds of ICR modes:
(1.1) complete set Chinese style ICR, be that ICR function effector concentrates on certain separate nodes, this separate nodes can be positioned over other position in eNodeB, RRM SERVER or the network, its concentrative implementation ICR controlled function, carry out the management of minizone load management and presence of intercell interference, other eNodeB or sub-district are by the manager;
(1.2) complete distributed I CR, be that ICR function effector is distributed on each eNodeB, each eNodeB is had an ICR controlled function, eNodeB can with the eNodeB that the ICR relation is arranged with it on every side manager and by the manager each other, carry out the management of minizone load management and presence of intercell interference;
(1.3) concentrate and distribute and deposit formula ICR, be that ICR function effector is present on certain separate nodes and the eNodeB simultaneously, be that the functional entity that part is relevant with ICR information in the evolvement mobile network is controlled by this separate nodes, part eNodeB controls himself function relevant with ICR information;
For the ICR collection initiator, it may be eNodeB, or certain separate nodes, or OMC;
For the ICR informant, it is eNodeB or sub-district;
For ICR information preserver, it may be distributed in each eNodeB, perhaps is summarised in the separate nodes at ICR function effector place, perhaps is present in the separate nodes at eNodeB and ICR function effector place simultaneously;
(2) in evolvement mobile network, there is RRM SERVER, but when RRM SERVER just deposits the ICR database of information:
For ICR function effector, there are three kinds of ICR modes:
(2.1) complete set Chinese style ICR, be that ICR function effector concentrates on certain separate nodes, this separate nodes can be positioned over other position in eNodeB, RRM SERVER or the network, its concentrative implementation ICR controlled function, carry out the management of minizone load management and presence of intercell interference, other eNodeB or sub-district are by the manager;
(2.2) complete distributed I CR, be that ICR function effector is distributed on each eNodeB, each eNodeB is had an ICR controlled function, eNodeB can with the eNodeB that the ICR relation is arranged with it on every side manager and by the manager each other, carry out the management of minizone load management and presence of intercell interference;
(2.3) concentrate and distribute and deposit formula ICR, be that ICR function effector is present on certain separate nodes and the eNodeB simultaneously, be that the functional entity that part is relevant with ICR information in the evolvement mobile network is controlled by this separate nodes, part eNodeB controls himself function relevant with ICR information;
For the ICR collection initiator, it may be eNodeB, also may be RRM SERVER, or OMC;
For the ICR informant, it is eNodeB or sub-district, and perhaps when the non-RRM SERVER of ICR collection initiator, the ICR informant can be RRM SERVER;
For ICR information preserver, it is RRM SERVER, and perhaps eNodeB also has hold function simultaneously;
(3) have RRM SERVER in evolvement mobile network, RRM SERVER deposits the ICR database of information, and RRM SERVER is when having the ICR controlled function
For ICR function effector, it is RRM SERVER, perhaps allows part eNodeB to have function effector identity, and the ICR controlled function relevant with this eNodeB carried out by this eNodeB;
For the ICR collection initiator, it may be eNodeB, perhaps may be RRM SERVER, or OMC;
For the ICR informant, it is eNodeB or sub-district, and perhaps when the non-RRM SERVER of ICR collection initiator, the ICR informant can be RRM SERVER;
For ICR information preserver, it is RRM SERVER, perhaps may be eNodeB.
At above-mentioned introduction to ICR function effector, no matter be distributed or centralized ICR, for some eNodeB, can require those eNodeB not possess ICR function effector's identity, so those eNodeB will be in the ICR function control by the manager, by other node or eNodeB management, participate in the realization of functions such as presence of intercell interference management and minizone load management with ICR function effector identity.
When having RRM SERVER in the evolvement mobile network, control and management at the ICR function of RRM SERVER, have the network management platform OMC of RRM SERVER in the evolvement mobile network simultaneously, it has the ICR controlled function, the object of signaling process is similarly eNodeB, so the OMC that mentions in the following steps all refers to the OMC of eNodeB or the OMC of RRM SERVER.
Below in conjunction with concrete flow process, the method among the present invention is described further:
Fig. 8 is that ICR collection initiator in the evolvement mobile network, informant, information preserver and ICR function effector relation are provided with flow chart, as shown in Figure 8, the steps include:
Step (801), OMC/ radio-resource-configuration control module are provided with above-mentioned four relation to the relation setting command that eNodeB sends ICR collection initiator, informant, information preserver and ICR function effector;
In ICR collection initiator, informant, information preserver and ICR function effector's relation setting command, do not force this pass to tie up to setting simultaneously in the message;
After step (802), eNodeB receive relation setting command, handle, and response is set to OMC/ radio-resource-configuration control module answer ICR collection initiator, informant, information preserver and ICR function effector's relation; Wherein, relation is provided with response and comprises and be arranged to merit message or failed message is set, if relation is provided with response for failed message is set, then carries ICR information setting failure cause in failed message is set.
After above-mentioned eNodeB receives relation setting command, after being treated to eNodeB and receiving relation setting command, ICR collection initiator, informant, information preserver and ICR function effector's relation is determined according to the content in the relation setting command.
The flow process of above-mentioned steps (801), (802) can be set up in the process in the sub-district, and the flow process of setting up with the sub-district merges, and promptly determines above-mentioned four relation in the process that the sub-district is set up, and as shown in Figure 9, the steps include:
Step (901), OMC/ radio-resource-configuration control module send the sub-district to eNodeB and set up request E-CELL SETUP REQUEST message, the relation setting command that comprises ICR collection initiator, informant, information preserver and ICR function effector in this E-CELL SETUP REQUEST message is provided with ICR collection initiator, informant, information preserver and ICR function effector's relation;
This E-CELL SETUP REQUEST message is on the CELL SETUPREQUEST message basis of existing UMTS system, keeps its most of function, increases the CELL SETUP REQUEST message of the evolution of related content formation in message; NBAP signaling with E-CELL SETUP REQUEST message is example, and is as shown in table 1, increased ICR informational message unit in E-CELL SETUP REQUEST message, and the ICR informational message comprises in the unit:
" ICR collector ID " message elements, this message elements is one or one group of message elements, its content comprises ICR information preserver sign, this sign may be an ID, as integer type numeral or other value types, in order to mark ICR information preserver's identity, the relation by this sign can help ICR informant foundation and ICR information preserver finds ICR information preserver; This sign also may be the information of an IP address or other address formats;
" ICR reporter ID ", whom is used for identifying is the ICR informant;
" ICR initiator ID ", being used for identifying is ICR information gathering by whose initiation;
" ICR Controller ID ", being used for identifying is who carries out the ICR controlled function.
Step (902), eNodeB handle after receiving E-CELL SETUP REQUEST message, and reply the sub-district to OMC/ radio-resource-configuration control module and set up response E-CELL SETUP RESPONSE message; When failure is set up in the sub-district, then eNodeB replys the sub-district to OMC/ radio-resource-configuration control module and sets up failure E-CELL SETUP FAILURE message, and in this message, carry ICR information setting failure cause, can't correspond to corresponding RRM server or eNodeB as the ICR information preserver who is disposed, perhaps ICR function effector can't find or the like; Provided the incorrect ICR information setting of an ICR information preserver failure cause in the table 2.
After above-mentioned eNodeB receives E-CELL SETUP REQUEST message, after being treated to eNodeB and receiving E-CELL SETUP REQUEST message, according to the content in the ICR informational message unit to ICR collection initiator, informant, information preserver and ICR function effector's relation is determined.
