Description
Technical field
The present invention relates to evolvement mobile network, refer in particular to the sending method and the ICR formation gathering method of ICR information measurement report in a kind of evolvement mobile network.
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 Switched Domain, circuit commutative field) and PS (PacketSwitched Domain, packet-switched domain) in logic.Fig. 1 is a UMTS system configuration schematic diagram, and as shown in Figure 1, UTRAN (UMTS Territorial Radio Access Network, UMTS Terrestrial radio access network), CN and UE (User Equipment, 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 Rel6 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 specific O﹠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 TS 25.433 V6.8.0 (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, interfere information, frequency or the carrier wave etc. of sub-district, abbreviates ICR information as; But ICR information is not limited to above information, needs only the information that the ICR controlled function is worked, and can be called ICR information.
At present, LTE is to RRM information, ICR information and Logical O﹠amp; M has proposed some new demands, needs to consider LogicalO﹠amp as mentioning under the central controlled mode of RRM at the chapters and sections 6.12.4Centralised of 3GPP TR R3.018 V0.1.0 (2006-01) Handlingof certain RRM Functions; The realization of M.
At chapters and sections 6.12.2.5 Inter-cell RRM (interference management ﹠amp; Loadmanagement) mention in (ICR):, need inter-cell RRM because power disturbance and cell load are unequal; Inter-Cell RRM 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-Cell RRM also be need or the like situation.Except presence of intercell interference management and the management of minizone load balancing, the category that also belongs to ICR is switched in the minizone.
Mention for UMTSR99-Rel-g in chapters and sections 6.12.2.6 Radio 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 RRM server (RRM server), or adjacent a plurality of eNodeB (base station 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.
Simultaneously, in the evolution mobile communication system, a base station may have a sub-district under its command, also may have a plurality of sub-districts under its command.
The frequency bandwidth of each sub-district is the same usually.The carrier frequency resources of sub-district can be divided into the centre frequency of using at center of housing estate, at the marginal frequency of cell edge according to the use difference.These frequencies generally can be divided into a plurality of subcarriers.For example the carrier cell of a 5M bandwidth can be that a subcarrier segments according to the bandwidth of 15KHZ.When Resource Scheduler carries out scheduling of resource, be unit generally according to subcarrier.
Because neighbor cell can have identical subcarrier, so, when the same sub-carrier of neighbor cell is used in the central area of adjacent sub-district separately, can not cause presence of intercell interference, but work as identical son in the edge of carrier wave use, will cause interference between the sub-district of these use same edge frequencies at neighbor cell.Therefore, each sub-district need know that (how detailed the past now, in the future), have on earth as for this operating position, may different requirements be arranged different algorithms for the frequency operating position of neighbor cell in the allocations of edge frequency.At present, studying and how to avoid this resource allocation to repeat the interference that causes in the cell edge area, need collect ICR information accurately.
Summary of the invention
At above the deficiencies in the prior art, the objective of the invention is to, a kind of sending method and ICR formation gathering method of ICR information measurement report are provided, in evolvement mobile network, when having at least one ICR information preserver, make the ICR informant ICR information can be reported ICR information preserver; And provide the accurate collection of ICR information.
For realizing this purpose, one embodiment of the present of invention provide a kind of sending method of ICR information measurement report, when having at least one minizone RRM ICR information preserver, comprising:
The ICR informant sends ICR information measurement report message to ICR information preserver.
Another embodiment of the present invention also provides a kind of ICR formation gathering method, sets up in base station initiated, sub-district or after the sub-district rebuilds, and obtains the ICR information of the ICR Control Node that is associated with this base station or sub-district.

Above-mentioned 4 flow processs all are part or all expansion that center among ICR collection initiator, informant, information preserver and the ICR function effector, at first, to the follow-up ICR collection initiator of mentioning, informant, information preserver and ICR function effector's notion and between relation do following introduction:
At ICR information, evolvement mobile network has proposed ICR collection initiator, informant, information preserver and ICR function effector's notion, and rises to functional entity in evolvement mobile network:
The evolution mobile system uses the OFDMA technology, and it provides technical foundation for the carrier wave of sub-district 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 cell load management and area interference management, and we are referred to as the ICR controlled function, and possess the functional entity of this control ability, and we are referred to as ICR function effector; As its name suggests, the functional entity that can initiate ICR information gathering is referred to as the ICR collection initiator; The functional entity or the node of ICR information are provided, are referred to as the ICR informant; And be responsible for preserving the functional entity or the node of ICR information, be referred to as ICR information preserver.
Determining of ICR collection initiator, informant, information preserver and ICR function effector functional entity relation also can be distinguished to some extent because of the difference of other functional entity that exists in the evolvement mobile network, and be specific as follows:
Fig. 4 is OMC and an eNodeB connection diagram in the evolvement mobile network, as shown in Figure 4, in the evolvement mobile network, RRM SERVER (RRM server, the RRM server) is the functional entity that to select, it is represented by dotted lines in the drawings, according to the existence of RRMSERVER in the evolvement mobile network whether, and the difference of when RRM SERVER exists, carrying out function, ICR collection initiator, informant, information preserver and ICR function effector functional entity are specific as follows:
(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 RRMSERVER, 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.
