The signaling process figure of the method for the another kind of interference monitoring that Fig. 6 provides for the embodiment of the present invention.The present embodiment is a specific embodiment of a certain MTC equipment access LTE network.As shown in Figure 6, the handling process of this interference MTC equipment comprises:
When step 61:eNodeB starts working, MME subscribes to interference monitoring event to eNodeB.Concrete, eNodeB sends " S1 SETUP REQUEST " message to MME, and request is started working.MME returns to " S1 SETUP RESPONSE " message to eNodeB.MME can need to trigger eNodeB and detect interference incident according to setting in advance, as MME in " S1 SETUP RESPONSE " message subscribes to interference monitoring event to eNodeB, makes eNodeB that the current disturbed zone position information monitoring is sent to MME.For example, in message, carry cell " Jamming Required "-for subscribing to interference monitoring event, make eNodeB that the current disturbed regional location monitoring is sent to MME.Further, the granularity that can indicate current disturbed regional location to send in " S1 SETUP RESPONSE " message is the form of expression of disturbed zone position information.For example,, based on ECGI, based on TAI or based on concrete physical location (longitude and latitude) etc.
Step 62:MTC equipment access LTE network, MTC equipment sends registration request by eNodeB and for example adheres to request (Attach Request) to MME;
Step 63:MME and HSS are mutual, obtain the subscription data of MTC equipment.
If MTC is User (MTC user), the MTC equipment under it is had to the demand of interference monitoring, first MTC User can subscribe to interference monitoring to operator and be about to interfere information transmission MTC server.After subscription, the subscription information of interference monitoring is stored in the subscription data of the upper MTC equipment of HSS.
The form of expression of the subscription information of interference monitoring can be that configuration needs network to carry out the mark of interference monitoring to it in the subscription data of MTC equipment, as configuration " MTC Feature-Jamming Indication ".
Follow-up MME obtains the subscription data of MTC equipment from HSS, if wherein comprise " MTC Feature-Jamming Indication ", MME need to carry out interference monitoring to this MTC equipment, particularly, the current disturbed zone position information that MME provides by reception access network elements matches the equipment in the MTC of disturbed state, the disturbed information of described MTC equipment is sent to MTC server, or described current disturbed zone position information is sent to MTC server.
The form of expression of the subscription information of interference monitoring also can configure the mark that needs network to carry out interference monitoring in Shi group (MTC Group) subscription data.For example, configuration " MTCFeature-Jamming Indication " in group's subscription data.
Follow-up MME obtains group's subscription data, if comprise " MTC Feature-Jamming Indication " in group's subscription data, MME needs Dui Ci group to carry out interference monitoring.Particularly, when MME confirms that in network, existence is disturbed, notify in time the concrete regional location of MTC server to exist and disturb.The granularity that can indicate interference monitoring event to send in mark is the form of expression of zone position information, for example, and based on ECGI, based on TAI or based on concrete physical location (longitude and latitude) etc.
In addition, if MME does not subscribe to interference monitoring event to eNodeB in step 61, now MME can also subscribe to interference monitoring event to eNodeB.For example, MME sends " MMECONFIGURATION UPDATE " message to eNodeB, and in " MME CONFIGURATIONUPDATE " message, MME subscribes to interference monitoring event to eNodeB.For example, in message, carry cell " Jamming Required "-for subscribing to interference monitoring event, make eNodeB that the current disturbed zone position information monitoring is sent to MME.Further, the granularity that can indicate interference monitoring event to send in " MME CONFIGURATIONUPDATE " message is the form of expression of zone position information, for example, and based on ECGI, based on TAI or based on concrete physical location (longitude and latitude) etc.
In addition, in subscription data, can also configure to interference monitoring event and send relevant information, for example, the MTC server address information that interference monitoring event need to send.
Because interference monitoring is not the demand of all M2M application, and the consumption of network resources that interference monitoring can be extra, therefore can carry out specific charging based on interference monitoring event.
Step 64:MME returns to registration response to UE and for example adheres to acceptance (AttachAccept).
Step 65:eNodeB monitors affiliated wireless environment, has while disturbing the interference monitoring event subscription based on MME or according to self default configuration, eNodeB disturbs to MME notice when eNodeB confirms wireless environment.For example, eNodeB transmission " JAMMING INDICATIOAN or Notify Request " message, to MME, is informed in current wireless environment and is disturbed.For example, in message, carry " Jamming Indication "-be used to indicate current wireless environment and have interference, in message, carry in addition corresponding current disturbed zone position information.Especially, eNodeB can confirm proper communication that current interference is enough to affect MTC equipment and network as MTC equipment cannot access network, in the uncontrollable situation of current interference, to the interference of MME notice.The zone position information that in " JAMMING INDICATIOAN " message, portability occur to disturb as disturbed based on ECGI, TAI or concrete physical location (longitude and latitude) etc.The granularity of described zone position information is that the form of expression can be according to the subscription of MME or eNodeB default configuration.
Further, when interference is eliminated, eNodeB can also send the elimination information of disturbing to MME.For example, eNodeB sends " JAMMING CLEAR INDICATIOAN or Notify Request " message to MME, informs in current wireless environment and disturbs and eliminate.The zone position information that carries to eliminate interference in " JAMMING CLEAR INDICATIOAN or Notify Request " message as disturbed based on ECGI, TAI or concrete physical location (longitude and latitude) etc.The granularity that described zone position information sends can be according to the subscription of MME or eNodeB default configuration.
Step 66:MME receives the current disturbed zone position information that eNodeB sends, and according to the description of step 63, confirmation need to be carried out interference monitoring, and processes.
In above-mentioned steps 63, the mode of MTC User subscription interference monitoring is that when in the subscription data of MTC equipment, configuration needs network to carry out interference monitoring to it, processing method of interfere information comprises:
Step 66a:MME matches the equipment in the MTC of disturbed state according to current disturbed zone position information.For example, by searching the context of the MTC equipment of preservation, if current disturbed region belongs to or be contained in effective coverage of current MTC equipment, confirm that MTC equipment is disturbed.
The method of the interference monitoring that the embodiment of the present invention provides is applicable to the fixing MTC equipment of location comparison.
For the fixing MTC equipment of location comparison, MME ratio is easier to confirm whether MTC equipment belongs to current disturbed region.The method that MME obtains the relative fixed position of MTC equipment information has two kinds:
First method is according to the more fixing MTC equipment in a kind of position, and its positional information can be used as subscription data, and the subscription data when MME obtains MTC equipment from HSS, has also just obtained the positional information of MTC equipment, and be kept in context.General is all the granularity of ECGI.
Second method can configure corresponding characteristic according to the more fixing MTC equipment in position in its subscription data, and for example, MTC Feature is configured to " Low Mobility ".MTC equipment is initiated attachment flow, and the subscription data that MME obtains MTC equipment from HSS, has also just obtained MTC equipment and had compared with the characteristic of fixed position information.While carrying out attachment flow (Attach procedure) as MTC equipment, eNodeB will provide equipment current residing ECGI to MME, and the default position information of MME using current MTC equipment present position information as this MTC equipment is kept in its context.
If confirm, disturbed MTC equipment subscribed to interference monitoring simultaneously, the MTC server that MME need to the information notification in disturbance state be corresponding by MTC equipment.
In addition, for confirming disturbed MTC equipment, MME can be set to disturbance state, for example, marker bit " JAMMING FLAG " is hereinafter set thereon.For confirming disturbed MTC equipment, the event that follow-up MME receives corresponding downlink data or signaling will can not trigger descending beep-page message, because the existence of disturbing, network side cannot communicate with MTC equipment.Once disturb, remove " the JAMMING CLEAR INDICATIOAN " message that receives eNodeB transmission as MME, MME can remove the interfered with terminal having arranged, and now MTC equipment recovers normal, can save effective Internet resources.It is more fixing that such calling optimization is equally relatively suitable for position, i.e. the MTC equipment of " LowMobility " type.
The information that step 66b:MME is in disturbed state by MTC equipment is directly passed to MTC server.For example, MME sends " Jamming Indication " message to MTC server, carries for identifying the identification information of the MTC equipment that is in disturbed state in " Jamming Indication " message; Or pass to MTC server by the 3rd network element as the information that HSS, GGSN, P-GW etc. are in disturbed state by MTC equipment.
In above-mentioned steps 63, the mode of MTC User subscription interference monitoring also can configure while needing network to carry out interference monitoring in Shi group subscription data, and the processing method of interference monitoring event comprises:
The interfere information that step 66c:MME sends eNodeB is transmitted to MTC server.MME confirms to subscribe to the group of interference monitoring by context, and the current disturbed zone position information that eNodeB is sent is transmitted to corresponding MTC server.For example, MME sends " Jamming Indication " message and, to MTC server, also needs to carry the identification information of group in message; Or MME passes to MTC server by the 3rd network element as the interfere information that HSS, GGSN, P-GW etc. send eNodeB.
Step 66d:MTC server matches the equipment in the MTC of disturbed state according to current disturbed zone position information.For example, MTC server can be according to the context of MTC equipment and current disturbed that zone position information matches the equipment in the MTC of disturbed state.Further, MTC server can carry out corresponding Check processing to the MTC equipment in disturbance state.
In above-described embodiment, access network elements carries out interference monitoring to wireless environment, and by the disturbed zone position information notice core network element monitoring, core network element finds disturbed MTC equipment according to the disturbed zone position information coupling receiving, and will be in the information notice MTC server of disturbed state; Or after current disturbed zone position information is sent to MTC Serve, MTC server just can match the equipment in the MTC of disturbed state according to current disturbed zone position information, realized interference signal cause MTC equipment cannot with the situation of network service under, by the information that is in disturbed state, notify the server to MTC, improved the fail safe of M2M application.
