Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of wireless resource management and method and a kind of radio resource information updating system and method.
Background technology
At micro-wave access global inter communication (Worldwide Interoperability for MicrowaveAccess, abbreviation WiMAX) in the network, access service network (Access ServiceNetwork, be called for short ASN) utilize RRM (Radio ResourceManagement is called for short RRM) function to improve the efficient of network radio resources and increase network capacity.The main purpose of RRM functional entity has:
1) triggers the measurement of being undertaken by base station (Base Station is called for short BS) and travelling carriage (Mobile Station is called for short MS) relevant with Radio Resource;
2) the corresponding measurement result of report in the network database and safeguard corresponding database;
3) other functional entitys (especially switching controls entity and service quality (Quality of Service is called for short QoS) management entity) provide the wireless resource information of collecting in ASN;
4) provide the wireless resource information of dynamic neighbor base station for certain base station.
The functional entity of RRM can be divided into radio resource agent (Radio ResourceAgent is called for short RRA) and radio resource controller (Radio Resource Controller is called for short RRC).
The effect of RRA has: trigger the measurement of Radio Resource; Allow other entities in the base station obtain wireless resource information; Give RRC with measurement report; Receive the information of neighbor base station from RRC.
The effect of RRC has: the RRA collection that management is related with it; The Radio Resource of holding the zone uses database; The request measurement report; Collect the wireless resource information of other functional entitys of ASN inside; Download neighbor base station information to RRA.
The RRM network reference model of WiMAX network standard definition at present mainly is divided into (intra-ASN) Configuration Framework in three kinds of access service networks, i.e. Profile A, Profile B and Profile C to an access service network.
In Profile A, the reference model of RRM as shown in Figure 1.In Fig. 1, RRC is arranged in ASN-GW, and RRA is arranged in BS, and the communication between RRC and the RRA is the R6 reference point by the WiMAX standard definition.Connect by the R4 reference point between the RRC among different ASN-GW.
In Profile B, because ASN-GW and BS merge in a physical entity, so RRC and the RRA physical entity that also exists together.Communication interface between RRC and the RRA is open, so the communication between them only is the mode of a specific implementation, and the WiMAX standard will not done regulation.
In Profile C, the reference model of RRM as shown in Figure 2.In as 2, RRC and RRA are located among the BS, do not have disclosed standard interface between them.But in ASN-GW, there is the entity of a similar RRC, is called the RRM relaying, be used for transmitting the communication information between the RRC among the different B S.It should be noted that the RRM relaying in ASN-GW only plays relaying, can not start to control making usefulness to Radio Resource, that really Radio Resource is controlled only is RRC among the BS.RRC under the same ASN-GW among the different B S communicates to be needed by the R6 reference point; Communication between the RRC under different ASN-GW also needs to carry out relay transmission by the R4 reference point.
According to the RRM framework definition of present WiMAX, (intra-ASN) RRM administrative messag has in access service network:
1) in Profile A, RRM has three class message:
Per-BS Spare Capacity Request and Report (request of single base station idle capacity and report)
Neighbor BS Resource Status Update (renewal of neighbor base station resource situation)
Per-MS PHY Parameters Request and Report (request of single mobile station physical layer parameter and report)
2) in Profile B,, therefore there is not corresponding message definition owing to there is not open interface between the RRM functional entity.
3) in Profile C,, therefore only defined a class message: Per-BS Spare Capacity Request and Report (request of single base station idle capacity and report) because RRC and RRA are in together among the BS.
At present the RRM framework of WiMAX is defined in also that (inter-ASN) has a class RRM message between access service network, is used for the communication between the RRC of different ASN: Per-BS Spare Capacity Request and Report (request of single base station idle capacity and report).
In the RRM framework of present WiMAX standard definition, there is Per-BS Spare Capacity Request and Report (request of single base station idle capacity and report) message to communicate between RRC between the RRC and RRA among the ASN, in different ASN-GW or the different ASN and the RRC; There is Neighbor BSResource Status Update (renewal of neighbor base station resource situation) message to communicate between RRC among the ASN and the RRA.Per-B S Spare Capacity Request and Report is used for RRC and reports its idle capacity to neighbor base station request and neighbor base station to this RRC; Neighbor BS ResourceStatus Update is used for RRC upgrades current resource situation from neighbor base station to serving BS.RRC is by upgrading to the collection of the resource situation of neighbor base station and to serving BS, reaches the management of network radio resources and auxiliary network such as are switched at the resource optimization function.
Fig. 3 is to Figure 5 shows that request of RRM idle capacity and report flow process.Figure 3 shows that wherein different ASN (also can comprise the flow process between the RRC in the different ASN-GW).Figure 4 shows that among the Profile A in the RRC of ASN-GW and the flow process between the RRA at BS.Figure 5 shows that among the Profile C in the RRC of BS and the flow process between the RRC among another BS.Figure 6 shows that among the Profile A at the RRC of ASN-GW and the RRM neighbor base station resource situation between the RRA at BS new technological process more.
Corresponding to Fig. 3 and Fig. 4, different ASN (idle capacity request and report idiographic flow between the RRC in or the different ASN-GW) and among the Profile A between RRC and the RRA are as follows:
RRC or the RRC in Profile A of RRC among the step 1:ASN#1 (or ASN-GW#1) in ASN#2 (or ASN-GW#2) sends " RRM-Spare Capacity Request (request of RRM idle capacity) " message to RRA, and neighbor base station or the pairing BS of RRC subordinate RRA that request is arranged in a certain appointment of ASN#2 (or ASN-GW#2) report its idle capacity information.Because this message and the present invention are irrelevant, so do not list message content at this.
RRC or the RRA in Profile A of RRC among the step 2:ASN#2 (or ASN-GW#2) in ASN#1 (or ASN-GW#1) sends " RRM-Spare Capacity Report (report of RRM idle capacity) " message to RRC, the idle capacity information of specified BS in the report request.Message content is as shown in table 1:
