Description
Technical field
The present invention relates to wireless communication field, particularly the distribution technique of physical resource.
Background technology
2006; Third generation partner program (3rd Generation Partnership Project; Abbreviation " 3GPP ") passed through high-speed data access (High Speed Packet Access; Be called for short " HSPA ") the evolution research project, the evolution network framework of HSPA (being referred to as the HSPA+ network) will provide the user rate of high bit rate and shorter call delay based on packet domain (PS) business for the PS business; Circuit domain (CS) business for current 3G (Third Generation) Moblie (The Third Generation is called for short " 3G ") system will no longer be optimized.
In the HSPA+ network, radio network controller (Radio NetworkController is called for short " the RNC ") function of existing 3G system has been put on the evolution HSPA base-station node (NodeB+) all.With being connected of core net, as shown in Figure 1, see that from the chain of command angle NodeB+ is directly continuous with GPRS serving GPRS support node (Serving GPRS Support Node is called for short " SGSN ") through the control interface of Iu-PS; See from the user plane angle; NodeB+ can be through user plane process SGSN and ggsn (the Gateway GPRS SupportNode of Iu-PS; Be called for short " GGSN ") connect, also can directly link to each other with GGSN through single tunnel approach (one tunnel approach).
Because in the HSPA+ network; The core net of NodeB+ and CS (Core Net; Be called for short " CN ") there is not the connection of user plane between the node, like mobile switching centre's (Mobile Switching Center is called for short " MSC ")/VLR Visitor Location Register (Visitor Location Register; Therefore the business of CS can not be provided separately abbreviation " VLR ").In order to have backwards compatibility, promptly in order to support CS professional, need to realize supporting the HSPA+ network that PS is professional and support PS simultaneously and legacy network that CS is professional between interconnect.
According to above-mentioned situation; Existing HSPA+ network design scene mainly contains two kinds, and is as shown in Figure 2, and Fig. 2 (a) is a HSPA+ independence deployment scenario; NodeB+ under this scene only supports PS professional; Promptly have only the PS business to insert core net through this NodeB+, the CS business still need could insert core net through the NodeB and the RNC of legacy network, has the Iur interface between the RNC of NodeB+ and legacy network; Fig. 2 (b) is that the HSPA+ carrier frequency is shared deployment scenario; Under this scene; The NodeB+ of HSPA+ network supports the access of eating dishes without rice or wine that PS is professional and CS is professional simultaneously; Wherein the PS business can directly insert core net through NodeB+, and the CS service needed inserts core net by the RNC of NodeB+ and legacy network, has the Iub/Iur interface between NodeB+ and the RNC.In addition, HSPA+ independence deployment scenario and HSPA+ carrier frequency are shared deployment scenario also can be present in a network jointly, and Fig. 3 shows the schematic network structure that two scenes combine.
It is thus clear that in the prior art, professional in order to support CS, the NodeB+ of HSPA+ network and the base-station node of legacy network (NodeB) can cover same area.
As for independent deployment scenario; Because the NodeB+ of HSPA+ network can only support PS professional, mainly is arranged in some hot spot regions, then also will pass through traditional RNC and NodeB to the support that CS is professional; Therefore; In order to support CS and PS professional simultaneously, require certain geographic location area that NodeB+ covered under the independent deployment scenario usually, also should be covered by the NodeB that traditional RNC controlled.This NodeB+ uses different frequencies with NodeB, does not disturb with frequency between the two.
Share deployment scenario for carrier frequency,, then also will pass through NodeB+ and traditional RNC the support that CS is professional because the NodeB+ of HSPA+ network can only support PS professional; Or NodeB and RNC through legacy network; Therefore, professional in order to support CS and PS simultaneously, the NodeB+ that requires carrier frequency to share under the deployment scenario usually should be connected with the RNC of legacy network; The coverage of this NodeB+ possibly overlap with the coverage of the NodeB of RNC control; For the zone that overlaps, this NodeB+ uses different frequencies with NodeB, does not disturb with frequency between the two.
Inventor of the present invention finds, for NodeB+ and the NodeB that coverage overlaps, uses different frequency resources, non-interfering mode to make separately and can't more effectively utilize Limited resources.Because NodeB+ and the employed frequency resource of NodeB are stipulated; Can not be complementary with the loading condition of equipment in the practical business process; Therefore possibly occur: a side business is very idle; Its frequency resource is vacant in vain, and the opposing party's business is very busy, the not enough situation about using of its frequency resource.When upward the PS business is very idle such as NodeB+, not high to the utilance of frequency; NodeB is but very busy at this moment, and resource is used inadequately, thereby has caused the unreasonable of the utilization of resources, and is not high to the frequency resource utilization.
Summary of the invention

Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that execution mode of the present invention is done to describe in detail further below.
First embodiment of the invention relates to resource allocation methods in a kind of communication system, and in this execution mode, first Radio Network System and second Radio Network System are held consultation, and distributes the physical resource of being controlled according to negotiation result.This first Radio Network System and second Radio Network System have at least on coverage and partially overlap; Because physical resource can have dynamic assignment between the Radio Network System of coincidence on covering; So can carry out reasonable distribution to physical resource according to the factors such as load of Radio Network System; It is not enough to avoid occurring a part of Radio Network System resource, and the problem that another part Radio Network System resource is idle has improved physical resource utilization.
In this execution mode; What hold consultation is Radio Network System, and said in the embodiment of the present invention having at least situation about partially overlapping to be meant that a Radio Network System has part or all of overlapping with another Radio Network System on coverage on the coverage.
Alleged Radio Network System is a logical concept in the embodiment of the present invention, and in the network of reality, Radio Network System can be radio network controller (RNC) and the system of base-station node NodeB that comprises in the legacy network; It also can be the system that comprises the evolution base station node NodeB+ among the evolution high-speed data access network HSPA+; It can also be the system that comprises the evolution base station node eNodeB among the long-term evolving network LTE.
Be the legacy network system with first Radio Network System below, second Radio Network System is that the HSPA+ network system is that example describes.This negotiations process is carried out between the RNC of the NodeB+ of HSPA+ network and legacy network.In the process of its negotiation mutual information can comprise physical resource, both sides' load information, frequency point information, code resource information, cell information, RNC/NodeB+ information, cell capacity of request etc.
Idiographic flow is as shown in Figure 4; In step 401; On NodeB+, exist the current physical resource that is not used when (promptly having the physical resource that to distribute to RNC); NodeB+ sends indication to the RNC of this legacy network, and these can distribute to the information of the physical resource of RNC, are called available resource information.Can also comprise the temporal information that these physical resources can be used in this available resource information.Simultaneously, also can the loading condition of this NodeB+ together be sent to this RNC.
In this step, can be can be Event triggered periodically, also the opportunity that NodeB+ sends available resource information.Such as the information of the physical resource that is not used on NodeB+ can be periodically (as every at a distance from 5 seconds) with this NodeB+ sends to RNC; Perhaps when Event triggered, when changing like this available resource information, or NodeB+ is when receiving the RNC query requests, and the information that this NodeB+ of indication can be distributed to the physical resource of this RNC sends to this RNC.Adoptable mode is more, and is very flexible.
Need to prove that above-mentioned physical resource can comprise one of following or its combination in any: frequency resource, sign indicating number resource, sub-carrier resources; This yard resource comprises scrambler resource and/or channelization code resource at least.
In step 402, when RNC uses at least one physical resource of this available resource information indication at needs, send the request message of this physical resource of request to NodeB+.Physical resource, the time of request use, the hope of being asked be can specifically comprise in this request message and that NodeB or sub-district etc. given this physical source distributing.
In step 403, after NodeB+ receives this request message, judge that the current RNC that whether can distribute to of physical resource that this request message is asked uses.Use if can distribute to RNC, then get into step 404, return the operable response of this physical resource, then get into step 405 to this RNC.If the physical resource of being asked is current occupied or part is occupied, then get into step 406, return this NodeB+ to this RNC and go up other and can distribute to the information (being available resource information) of the physical resource of this RNC, then get into step 407.
In step 405; The current RNC that can distribute to of the physical resource of being asked uses; After RNC received the operable response of this physical resource, with the NodeB of this physical source distributing to its control, this NodeB had at least partial converage zone to overlap with NodeB+; In addition, RNC can also return acknowledge message to this NodeB+.
Perhaps; In step 404; NodeB+ can directly distribute this physical resource in the respective cell of NodeB this RNC control, this resource of needs use, in the case after this RNC returns the operable response of this physical resource; In step 405, RNC need not again with the NodeB of this physical source distributing to its control.In addition, RNC can directly return acknowledge message to this NodeB+.
In step 407; The physical resource of being asked is current to be taken by all or part of; After RNC received other available resource information that NodeB+ returns, the physical source distributing that this available resource information is indicated was given the NodeB that this RNC controlled, and this NodeB has at least partial converage zone to overlap with NodeB+; In addition, this RNC can also return acknowledge message to this NodeB+.
Perhaps; In step 406; NodeB+ is after this RNC returns other available resource information, directly at these other physical resources of NodeB corresponding district distribution this RNC control, that need to use this physical resource, in the case; In step 407, RNC need not again with the NodeB of this physical source distributing to its control.In addition, RNC can directly return acknowledge message to this NodeB+.
Need to prove that if the physical resource that above-mentioned RNC asked is current occupied or part is occupied, above step 406 is one of a kind of treating method.In fact, also the described method of step 406 can be do not adopted, the response message that RNC uses cannot be distributed to but return the physical resource of being asked to RNC; After said RNC received this response, execution in step 402 once more, sent the request message of other physical resources of request to this NodeB+.
Because in this execution mode, the last physical resource that can distribute to RNC of NodeB+ is to be controlled but the current physical resource that is not used by NodeB+, through this part resource being held consultation and utilizes, can the raising system in utilization ratio of wireless resources.
In step 408, after RNC discharges the physical resource that is distributed at this NodeB, notify the information of the physical resource that this NodeB+ discharges, thereby make this physical resource to be used by NodeB+, prevent to cause resource vacant because information is asynchronous.After this NodeB+ receives this notice, can return acknowledge message.
In addition, in step 408, if before the NodeB of this RNC control discharges the physical resource that is distributed; Variation has taken place in the load information of this NodeB+, becomes very busy like business, needs to use this physical resource that is taken by NodeB; Then NodeB+ also can initiatively send the request that discharges the physical resource that is assigned with to RNC; After RNC receives this request, discharge shared physical resource, physical resource is returned to NodeB+.Thereby guaranteeing can not influence NodeB+ own resources operating position when resource-sharing, improving resource utilization.
In addition,, also can send the physical resource idle message, inform that this physical resource of RNC can be used by RNC to RNC if NodeB+ controls a certain physical resource but do not use for a long time, and the request message of the request physical resource of need not redispatching.After RNC receives this physical resource idle message, can send the response message of expression to NodeB+ to this free time physical resource operating position.This also can be regarded as consulting to distribute a kind of mode of physical resource.
Below this flow process is combined with a concrete example and describe.Such as under independent deployment scenario, the NodeB25 of NodeB+12 and RNC25 control covers same sub-district, and NodeB+12 has reserved a part of resource in advance and given RNC25 with the communication of this part resource.Perhaps, also can be that NodeB+12 regularly promptly can distribute to the physical resource of RNC to the information of the available resources of RNC25 circular oneself for example per 5 seconds on the NodeB+12.
It is professional that CS is initiated at the terminal; NodeB+12 is from public control channel (Common Control Channel; Be called for short " CCCH ") received corresponding wireless resource control connection request (RRC Connect Request), check confirm to be the request in CS territory after, be transmitted to RNC25 through the Iur interface.
This request is accepted in the RNC25 decision; But the current load of the NodeB25 that RNC25 controlled is bigger; So RNC25 begins to ask corresponding resource to NodeB+12; The request mode is following: RNC25 is according to the available resource information of circular before the NodeB+12, and selected required resource asks (RL Setup Request) message that the minimum of selected resource and this RNC25 resource requirement is required to send to NodeB+12 through Radio Link foundation.NodeB+12 judges; Confirm that the resource that RNC25 selects for use is taken wholly or in part; Thereby NodeB+12 sets up the minimum of indicating in the request message according to Radio Link and requires to carry out automatically resource allocation, on NodeB+12, setting up Radio Link in this terminal, and obtains down-going synchronous.Simultaneously, NodeB+12 returns Radio Link to RNC25 and sets up and to reply (RL Setup Request) message, sets up the information of carrying the physical resource that NodeB+12 redistributes in the response message at this Radio Link.Go up the current physical resource that is not used through sharing NodeB+12, can the raising system in utilization ratio of wireless resources, alleviate the nervous situation of RNC25 resource.
In said process; Shown in dash area in the table 1; RNC25 indicates the selected resource and the minimum requirement of this RNC25 resource requirement through set up maximum rate and the assurance speed that comprises uplink scrambling code, up channel coding minimum length, up Dedicated Physical Data Channel maximum number and Uu mouth (interface between RNC and the terminal) in the request at Radio Link.

Table 2
Equally; Shown in dash area in the table 3; This NodeB+12 comprises uplink scrambling code, up channel coding minimum length, up Dedicated Physical Data Channel maximum number, the information of the physical resource that indication NodeB+12 redistributes through setting up at Radio Link in the response message.
Table 3
This execution mode has explained that mainly the RNC of legacy network distributes the NodeB+ that uses evolvement network to go up the method for idling-resource through consultation, and corresponding, NodeB+ also can adopt the idling-resource on the same procedure shared RNC.
Second embodiment of the invention relates to resource allocation methods in a kind of communication system equally; Roughly the same with first execution mode, its difference is, in the first embodiment; NodeB+ initiatively sends available resource information to RNC; Be the information that can distribute to the physical resource of RNC on this NodeB+, RNC selectes physical resource according to this available resource information, and sends the request message of this selected physical resource of request to NodeB+; And in this execution mode; RNC is directly when needs use physical resource; Send the request message of request physical resource to NodeB+; Select to distribute to the concrete physical resource of this RNC by NodeB+, and return response message, in this response message, comprise and distribute to the physical resource that this RNC uses.
Scene below in conjunction with concrete describes this execution mode, in this execution mode, between NodeB+ and the RNC, can utilize information interaction (Information Exchange) process of Iur interface, realizes the negotiation to physical resource.
Specifically; Because in the prior art; Information interaction begins request (INFORMATIONEXCHANGE INITIATION REQUEST) message and is mainly used in exchange message between UMTS (Universal Mobile Telecommunications System is called for short " UMTS ") and the GSM.This execution mode increases evolution HSPA network cell (HSPA+Cell) in this message; The part of legacy network sub-district (UTRAN Cell); Shown in dash area in the table 4, make communicating by letter between sub-district that this message can be used in evolution HSPA (being HSPA+) network and the legacy network sub-district.
And; Begin in the information requested type (Information Type) in this information interaction that to have increased information type be request resource and give back resource two types to field information type project (Information Type Item), optional can also increase the affirmation resource type.Remove the restriction of the scope of application of this field simultaneously, shown in table 5 dash area.
Table 4
Table 5
When implementing; Requesting party such as NodeB+ send INFORMATION EXCHANGEINITIATION REQUEST message to RNC; Wherein Information Type Item is set to request resource, and NodeB+ also distributes a Transaction Identifier (Transaction ID) for it.Reciever such as RNC receive after this message that load information according to oneself, ability etc. judge; The physical resource that is not used if current existence is allocated in advance can offer NodeB+; Then RNC begins to reply (INFORMATION EXCHANGE INITIATION RESPONSE) message alternately to this NodeB+ return information, and is as shown in table 6.In requested data value (the Requested Data Value) field of this message, indicate available resource information, like frequency band or the scrambling code information that can distribute to NodeB+, as shown in table 7.Identical in the Transaction ID of this message and the INFORMATION EXCHANGE INITIATION REQUEST message.Through the current physical resource that is not used on the shared RNC, can the raising system in utilization ratio of wireless resources, alleviate the nervous situation of NodeB+ resource.
When the NodeB+ service ending; After discharging this physical resource; Send INFORMATIONEXCHANGE INITIATION REQUEST message to RNC once more, identical in this message of the Transaction ID of this message and transmission for the first time, Information Type Item be set to give back resource; After RNC receives this message, can confirm that according to Transaction ID NodeB+ will give back this physical resource; Afterwards; This RNC can return INFORMATION EXCHANGE INITIATION RESPONSE message to this NodeB+ once more; Transaction ID is constant, and Information Type Item is set to confirm resource, and this RNC of notice NodeB+ accepts this physical resource.Because after discharging the physical resource that is distributed, NodeB+ can notify the information of corresponding this physical resource that is discharged of RNC, thereby makes this physical resource to be used by RNC, prevents to cause resource vacant because information is asynchronous.
This execution mode has explained that mainly the RNC of the shared legacy network of NodeB+ of evolvement network goes up the method for idling-resource, and corresponding, RNC also can adopt same procedure to share the idling-resource on the NodeB+.
In addition; Between RNC and NodeB+, this execution mode can be applied between following any two Radio Network Systems equally: the eNodeB system of the system that the RNC of legacy network and NodeB form, the NodeB+ system of HSPA+ network, LTE network, other Radio Network Systems etc.Comprise between the RNC and RNC of legacy network, between the NodeB+ and NodeB+ of HSPA+ network, between the eNodeB and eNodeB of LTE network, between other Radio Network Systems etc., only need both overlay area to have at least to partially overlap and get final product.
