Abstract
The invention discloses a method of error in pool area educing network resources instruction, including: in the process of location updating that user equipment (UE) switches into the pool, CN node receives the request of UE location updating, and judge whether NRI in the request is consistent with that of itself and UE belongs to this pool user. If the two NRIs are consist and the UE doesn't belong to the pool where the CN node is, the CN node will inform the UE to re-launch location updating and re-select CN node in the manner of load balance.
Description
Technical field
The present invention relates to mobile communication technology, relate in particular to error derived network resource indication (Network Resource Indicator, processing method NRI) in the district of a kind of pond.
Background technology
Because the restriction of global system for mobile communications (GSM) on the speed of eating dishes without rice or wine, people begin more and more many sight stakes on 3-G (Generation Three mobile communication system) (3G), correspondingly various 3G standards also arise at the historic moment, 3GPP R99, the 3GPPR4 that formulates as 3G (Third Generation) Moblie collaborative project tissue (3GPP), 3GPP R5 etc.
Many Iu interface (Iu-Flex) technology is a kind of technology of stipulating among the 3GPP R5, it supports a base station controller (Base Station Control, BSC)/radio network controller (Radio NetworkController, RNC) (Core Network CN) connects routing function to node in the territory of node to a plurality of core net.Introduced the notion of Chi Qu (Pool Area) in the Iu-Flex technology, Chi Qu comprises all service areas of one or more BSC/RNC that one group of parallel C N node is served, subscriber equipment (User Equipment, UE) in this zone, move and need not to change service CN node, a plurality of CN nodes in the district of a pond can be realized load balancing, the service range that they provided covers whole Chi Qu, can reduce renewal, switching and the reorientation of CN intermediate node like this, reduce the renewal flow of attaching position register (HLR).
NRI is a key mark of selecting the CN node in the district of pond, upgrade or customer call for the position that UE initiates, access control equipments such as BSC/RNC are according to Temporary Mobile Subscriber Identity (Temp MobileSubscriber Identity, TMSI) (the MobileSwitch Center of NRI Information Selection mobile switching centre that comprises in, MSC)/service universal grouping wireless business supporting node (Service GPRSSupporting Node, CN node such as SGSN), and the message of receiving is routed to this CN node processing.In the district of whole pond, CN node of the value unique identification of each NRI, this value is distributed to UE by MSC/SGSN, NRI in the district of different pond disposes respectively, because the maximum occurrences of NRI is 1024, resource is very limited, therefore just the repeated use of different pond district NRI can occur unavoidablely.
When UE switches in different intervals, pond, if the NRI that UE uses just in time is the NRI that Yuan Chi district and purpose Chi Qu reuse, so, BSC/RNC in the district of purpose pond will inevitably derive NRI according to mistake and carry out route, this UE fixedly is linked on the CN node corresponding with this NRI in the district of purpose pond all the time, rather than is linked in the district of purpose pond according to the mode of load balancing.When especially the Dang Yuanchi district was adjacent with purpose pond district, if the interval user in pond moves frequently, so, through accumulation after a while, it was unusual to cause the load of pond district to occur.In addition, for the UE that moves to from non-Chi Qu in the district of pond, because the NRI position section among this user TMSI belongs to irregular state, so the very easy NRI mistake that occurs derives, if BSC/RNC derives NRI according to mistake and selects the CN node always, through after a while accumulation, it is unusual finally to cause the load of pond district to occur so.
Summary of the invention
In view of this, the object of the present invention is to provide the processing method of error derived network resource indication in the district of a kind of pond, it is unusual to avoid the load of pond district to occur.
For achieving the above object, technical scheme provided by the invention is as follows:
Switch in the position updating process of Chi Qu at user equipment (UE), after core net CN node is received the position updating request of UE initiation, judge that the Internet resources indications NRI that carries in the position updating request is whether consistent with self NRI, and judge whether this UE belongs to this pond district user, when consistent and this UE did not belong to this pond district, CN node place user as both NRI, this CN node was notified this UE to initiate the position again to upgrade and reselect the CN node according to the mode of load balancing.
Wherein, whether the described UE of judgement belongs to this pond district user and comprises:
Described CN node judges according to the Location Area Identification LAI that carries in the described position updating request whether described UE belongs to this pond district user.
Described notice comprises:
Described CN node sends the position of carrying particular network resource indication Null-NRI and non-broadcast location area Non-Broadcast LAI to described UE and upgrades response.
Further comprise after the described notice:
After UE receives that response is upgraded in described position, again send position updating request to access control equipment, carry Null-NRI and Non-Broadcast LAI in this position updating request, after access control equipment is received this position updating request, mode according to load balancing is this UE selection CN node again, and the position updating request of receiving is transmitted to the CN node of reselecting.
Access control equipment further comprises after position updating request is transmitted to the CN node of reselecting:
After the described CN node of reselecting is received this position updating request, re-execute position updating process, for described UE redistributes Temporary Mobile Subscriber Identity TMSI, and the TMSI that redistributes and local LAI are carried at the position upgrade in the response and send to UE, wherein, carry self NRI of the described CN node of reselecting among the TMSI.
Described access control equipment is base station controller BSC or radio network controller (RNC).
Described CN node is moving exchanging center MSC or service universal grouping wireless business supporting node SGSN.
This shows, in position updating process of the present invention, if access control equipment uses the wrong NRI that derives to select the CN node as UE, so, selecteed CN node will be notified this UE to initiate the position renewal again and reselect the CN node according to the mode of load balancing, can make the load of CN node in the district of pond reach balanced like this, and it is unusual to avoid the load of pond district to occur, thereby reduce the operation maintenance operation, improve the satisfaction of operator.
Description of drawings
Fig. 1 is the process flow figure of the wrong NRI of derivation in the embodiment of the invention.
Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, the embodiment that develops simultaneously with reference to the accompanying drawings is described in further detail the present invention.
Basic thought of the present invention is: switch in the position updating process of Chi Qu at UE, after the CN node is received the position updating request of UE initiation, judge that the NRI that carries in the position updating request is whether consistent with self NRI, and judge whether this UE belongs to this pond district user, when consistent and this UE does not belong to this pond district, CN node place user as both NRI, that is to say, when this CN node is judged when the NRI mistake having occurred this moment and deriving, this CN node is notified this UE to initiate the position again to upgrade and reselect the CN node according to the mode of load balancing.
Be BSC below with the access control equipment, the CN node is that MSC is an example, and the wrong processing method that derives NRI provided by the invention is described in detail, and referring to shown in Figure 1, the processing procedure in the present embodiment mainly may further comprise the steps:
Step 101:UE switches to purpose Chi Qu, eats dishes without rice or wine to be connected the process of foundation with BSC, sets up the wireless connections of eating dishes without rice or wine.
Wherein, described UE switches to purpose Chi Qu and comprises two kinds of situations: a kind of is the switching in interval, pond, and promptly UE switches to purpose Chi Qu from the Yuan Chi district; Another kind is to switch to purpose Chi Qu from non-Chi Qu.
Step 102:UE initiates the position and upgrades, and the BSC in the district of purpose pond sends position updating request (Location Updating Request).
After step 103:BSC receives Location Updating Request message from UE, derive NRI according to the TMSI that carries in the message, and select the service MSC of this UE according to the corresponding relation of NRI and MSC, in Fig. 1, suppose that the MSC of the NRI correspondence that UE uses is MSC_A.
In fact, BSC derivation this moment NRI is a kind of wrong derivation, such as, if this UE belongs to the user that Chi Qu switches, so, the NRI that this UE uses not is the NRI that purpose Chi Qu distributes as the NRI in Yuan Chi district, therefore, the use of this NRI is unusual.
Can't from the Location Updating Request message of receiving, derive the situation of suitable NRI for BSC, it is situation about not existing in the district of purpose pond with the corresponding CN node of NRI of deriving, BSC will select MSC according to the mode of load balancing, more new technological process is consistent with position of the prior art for concrete processing procedure wherein, gives unnecessary details no longer one by one here.The present invention can derive NRI at access control equipment from the Location Updating Request message of receiving from UE, and exists the situation with the corresponding CN node of NRI of deriving to describe in the district of purpose pond.
Step 104:BSC gives MSC_A with the Location Updating Request forwards of receiving.
After step 105:MSC_A receives the Location Updating Request message that BSC sends, the executing location renewal process, and judge according to the Location Area Identification that carries in this message (LAI) whether this UE belongs to the user of this Chi Qu, if do not belong to, then explanation the derivation of NRI mistake occurred this moment, and MSC_A distributes specific NRI (Null-NRI) and non-broadcasting LAI (Non-BroadcastLAI) for this UE.
Need to prove, because the UE in the present embodiment moves to the district of purpose pond from non-Chi Qu or Yuan Chi district, do not belong to the user of MSC_A place Chi Qu, therefore, step 105 shows the situation that UE does not belong to MSC_A place Chi Qu.More new technological process is consistent with position of the prior art for the processing of other situation, gives unnecessary details no longer one by one here.
Step 106:MSC_A is carried at the position with Null-NRI and Non-Broadcast LAI and upgrades in the response (Location Updating Accept) and send to BSC.
The Location Updating Accept message from MSC_A that step 107:BSC will receive is handed down to UE.
After step 108:UE receives the Location Updating Accept message that BSC sends, LAI in Non-Broadcast LAI that carries in this message and the system information broadcast that listens to is compared, it is inconsistent to find both, UE then initiates the position again and upgrades, and the BSC in the district of purpose pond sends the Location Updating Request message of carrying Null-NRI and Non-Broadcast LAI.
After step 109:BSC receives the Location Updating Request message that UE initiates again, find that the NRI that derives is Null-NRI, then by load-balancing algorithm according to the mode of load balancing again for this UE selects new service CN node, in Fig. 1, finally selected MSC_B.
Step 110:BSC gives MSC_B with the Location Updating Request forwards of receiving.
After step 111:MSC_B receives Location Updating Request message, judge this user according to the Non-Broadcast LAI that carries in this message and be migrated users in the pond, re-execute position updating process, and redistribute normal TMSI for this UE, wherein, can carry the NRI of MSC_B self among the TMSI.
Step 112:MSC_B is carried at the TMSI that redistributes and local LAI in the LocationUpdating Accept message and sends to BSC.
The Location Updating Accept forwards from MSC_B that step 113:BSC will receive is given UE.
So far, whole position updating process finishes.
If the service CN node that BSC reselects in the step 109 is that MSC_A is consistent with the CN node of UE initial registration, then MSC_A need not to carry out the mutual of position renewal with HLR again.
As seen, method provided by the present invention can make the load of CN node in the district of pond reach balanced, and it is unusual to avoid the load of pond district to occur, and reduces the operation maintenance operation, improves the satisfaction of operator.
The above has carried out further detailed description to purpose of the present invention, technical scheme and beneficial effect; institute is understood that; the above is not in order to restriction the present invention; within the spirit and principles in the present invention all; any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
