Description

A kind of Notification Method of evolved base station stationkeeping ability and equipment

Technical field

The present invention relates to mobile communication technology, particularly a kind of Notification Method and equipment of evolved base station stationkeeping ability.

Background technology

Fig. 1 is the positioning architecture schematic diagram of E-UTRAN (Evolution-Universal Terrestrial Radio Access Network, the global grounding wireless access network of evolution), and the positioning architecture relevant with E-UTRAN as shown in the figure.This framework is supported chain of command location and user's face location.In the chain of command position fixing process, target device is UE (User Equipment, subscriber equipment), the server of network side is E-SMLC (EvolvedServing Mobile Location Centre, evolved Serving Mobile Location Center), by the information interaction between relevant chain of command signaling realization UE, eNB (evolution base station), MME (Mobility Management Entity, Mobility Management Entity) and the E-SMLC, finish positioning function to terminal.User's face positioning trip on application layer, the server S LP of network side (SUPL Location Platform, SUPL locating platform; SUPL:Secure User Plane Location, user's face location) use SUPL agreement and target device UE to position the mutual of relevant information.May integrate between E-SMLC and the SLP, privately owned interface is perhaps arranged between the two, so can use part chain of command flow process in user's face location.

Fig. 2 is the positioning flow schematic diagram in LTE (Long Term Evolution, the Long Term Evolution) system, as shown in the figure, can comprise following process:

Step 201a, under MO-LR (Mobile Originated Location Request, initial terminal Location Request) situation, UE sends request for location services to MME by NAS (Non Access Stratum, Non-Access Stratum) message;

Step 201b or at MT-LR (Mobile Terminated Location Request, initiate by outside positioning service client) under the situation, EPC (Evolved Packet Core, evolution block core net) some entities in send request for location services to MME, for example this class entity has GMLC (GatewayMobile Location Center, GMLC);

Step 201c or under NI-LR (Network Induced Location Request, network-triggered Location Request) situation, MME is inner to initiate request for location services (particular location of UE need be provided during as urgent call);

Step 202, MME issue E-SMLC with request for location services, and E-SMLC selects suitable localization method according to the QoS as information such as locating accuracy and time delays that carries in this Location Request (Quality of Service, service quality);

Step 203a, E-SMLC may trigger the relevant position fixing process of eNB (evolution base station);

Step 203b, E-SMLC may trigger the relevant position fixing process of UE;

Step 204, E-SMLC send the positioning service response to MME, in the middle of comprised some required results (, locating successfully or the indication of failing etc.) as the position of UE;

Step 205a is if MO-LR, and MME gives UE restoring to normal position service response;

Step 205b is if MT-LR, and MME gives the corresponding entity restoring to normal position of EPC service response;

Step 205c is if NI-LR, and MME utilizes this positioning service response to support to trigger the service of step 201c.

From top LTE positioning flow figure as can be seen, position fixing process relates to 4 nodes, i.e. UE, eNB, MME and E-SMLC; Position fixing process always sends Location Request by MME to E-SMLC, E-SMLC is again according to this Location Request, select suitable localization method, for example: A-GNSS (Assisted GlobalNavigation Satellite System, the GLONASS (Global Navigation Satellite System) of network assistance), OTDOA (ObservedTime Difference Of Arrival, observe to arrive time difference measurements), E-CID (Enhanced Cell-IDpositioning method, the localization method based on sub-district ID of enhancing) etc.Therefore, E-SMLC need know the stationkeeping ability of above-mentioned 4 nodes.

User's face position fixing process can be divided into two kinds of situations.A kind of situation is the position fixing process that only uses user plane information mutual, another situation is the position fixing process (providing some auxiliary datas, measuring amount etc. as needing eNB in the position fixing process) that needs eNB to participate in, need use part chain of command flow process so that obtain required information when user's face is located so, Fig. 3 uses part chain of command schematic flow sheet in user's face position fixing process, need use part chain of command flow process to generally comprise following process when as shown in the figure, user's face is located:

Set up SUPL session (SUPL session) between step 301, UE and the SLP, use the SUPL agreement to position the mutual of relevant information;

Step 302, SLP are by L1p message required information in E-SMLC request position fixing process;

Step 303, the required information in the chain of command flow process acquisition position fixing process of passing through;

Step 304, E-SMLC pass to SLP by L1p message with information required in the position fixing process;

Step 305, if need, SLP passes to UE by LPP/SUPL with the information that is obtained, finish follow-up position fixing process, wherein, LPP/SUPL is meant and uses LPP (LTEPositioning Protocol on the SUPL agreement, the LTE location protocol) PDU (Packet Data Unit, Packet Data Unit).

Therefore, in user's face position fixing process, SLP is the same with E-SMLC, also needs to know the stationkeeping ability that participates in each node in the position fixing process, could select suitable localization method.

About UE in the position fixing process and the management of E-SMLC stationkeeping ability, the sub-working group of 3GPP RAN2 that is being responsible for LTE MAC (Medium Access Control, medium access control) layer technology and network layer Radio Resource control aspect research is at present discussed.And MME itself does not have any stationkeeping ability, can think its stationkeeping ability shows whether support the protocol procedures (as LPPa (LTE PositioningProtocol Annex) agreement) of being correlated with, and its stationkeeping ability can solve by deployment.

The eNB stationkeeping ability can be considered from agreement and two angles of function.Consider from the agreement angle eNB stationkeeping ability comprises mainly whether it supports the LPPa agreement; Consider from functional perspective, the eNB stationkeeping ability comprises the following aspects: support AOA (Angle of Arrival, arrival bearing's user measurement) measurement, support TA (Timing Advance, Timing Advance) measurement (comprising the maintenance, compensation of TA etc.), supports that the required X2 of OTDOA localization method is mutual, supports PRS (Positioning reference signals, location reference signals) and positioning subframe pattern (positioning sub-frame pattern) indication in the OTDOA localization method.In addition, because eNB stationkeeping ability difference, the certainty of measurement of its support also can be variant.Therefore, when reporting the eNB stationkeeping ability, may indicate its certainty of measurement.

The stationkeeping ability of supposing all sub-districts under the eNB is all identical, and deployment scenario is that not all eNB supports above-mentioned functions simultaneously under the MME, even can not support positioning function fully.In chain of command and user's face position fixing process, E-SMLC and SLP just need know the ability of eNB, could select suitable localization method then so.But the deficiencies in the prior art are: in present LTE system, also do not make E-SMLC and SLP can know the technical scheme of eNB stationkeeping ability.

Embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.

Fig. 4 is the Notification Method implementing procedure schematic diagram of evolved base station stationkeeping ability, as shown in the figure, can comprise the steps: in notification procedure

Step 401, MME determine the service evolved base station that described UE is current;

Step 402, in the stationkeeping ability of MME subordinate's evolved base station, determine the stationkeeping ability of the service evolved base station that described UE is current;

The stationkeeping ability notice E-SMLC of the service evolved base station that step 403, MME are current with described UE.

By such scheme as can be seen, in the enforcement, MME safeguards the stationkeeping ability of its subordinate's evolved base station, and initiatively the stationkeeping ability of the service evolved base station that UE is current is notified E-SMLC, can certainly be according to the stationkeeping ability notice E-SMLC of the inquiry of the E-SMLC service evolved base station that UE is current.

Find out by scheme, E-SMLC do not need directly and evolved base station mutual, but obtain the evolved base station stationkeeping ability there from MME.

In concrete the enforcement, evolved base station mainly includes at present: the eNB in LTE and the LTE-A system, HeNB (Home eNB, family base station), Relay Node other forms of wireless network nodes such as (via nodes) in the LTE-A system, to be that example describes mainly below with most typical eNB, obviously, the execution mode of eNB also natural energy applies to other forms of wireless network node, if these nodes in network with UE, MME, the annexation of E-SMLC, work relationship, function is relating to identical or similar can enforcement by the mode of eNB on the stationkeeping ability.

For the concrete enforcement of the Notification Method of eNB stationkeeping ability, will obtain the execution mode of eNB stationkeeping ability around MME below, in various positioning flows between MME and the E-SMLC between the stationkeeping ability of mutual eNB and SLP and the E-SMLC embodiment of the problems such as execution mode of the stationkeeping ability of mutual eNB launch explanation.

One, MME obtains the enforcement of eNB stationkeeping ability.

In the enforcement, two kinds of schemes can be arranged at least generally:

1, the eNB by each subordinate sets up or the message of transmission when S1 upgrades obtains at S1, carries the stationkeeping ability of this eNB in the described message; Concrete, when S1 set up, the message that each subordinate's eNB sends can be S1SETUP REQUEST message; Perhaps, when S1 upgraded, the message that each subordinate's eNB sends can be ENB CONFIGURATION UPDATE message.

Or, 2, start, restart or stationkeeping ability notice when changing by the eNB of OAM (Operations, Administration and Maintenance, Operations, Administration and Maintenance) under described MME.

That is, eNB sets up and S1 can be with own stationkeeping ability notice MME when upgrading at S1, perhaps in the eNB startup, restart or eNB stationkeeping ability when changing, notify MME by OAM with the stationkeeping ability of up-to-date eNB.

But, though enumerated above-mentioned dual mode in the enforcement, and do not meant that this two kinds of implementations are only arranged, in fact, theoretically, eNB can be at any time, by the stationkeeping ability of self being informed MME with MME message mutual, that can carry stationkeeping ability information.Above-mentioned dual mode only is used to instruct those skilled in the art specifically how to implement the present invention, but does not mean and only can use this dual mode, can need come to determine the concrete means of mutual stationkeeping ability between corresponding M ME and the eNB in the implementation process in conjunction with practice.

Example with this dual mode describes below.

Step 801, send request for location services to MME;

In this step, no matter be MO-LR, MT-LR or NI-LR, the End-Customer end all can send request for location services to MME;

Step 802, triggering Service Request (service request); Under MO-LR and M-LR situation, when MME sent request for location services, UE was in connection status with MME, then need not carry out this step; Under the MT-LR situation, when MME sent request for location services, UE may be in the ECM-IDLE state, then needed this moment to trigger ServiceRequest by network side, and foundation is connected with UE's, determines the service eNB that UE is current;

Step 803, MME determine the stationkeeping ability of service eNB;

The MME basis is the stationkeeping ability of canned data acquisition service eNB, and sends to E-SMLC with being carried in the Location Request message in this eNB stationkeeping ability step 804 below;

Step 804, MME send the Location Request that contains the eNB stationkeeping ability to E-SMLC;

Step 805, E-SMLC select suitable localization method;

In this step, stationkeeping ability according to the QoS that carries among the Location Request (as information such as locating accuracy and time delays) and these 4 nodes of UE, eNB, MME and E-SMLC, E-SMLC selects suitable localization method, and triggers processes such as concrete location survey and location Calculation;

Step 806, position and measure and calculate.

In the chain of command position fixing process, the situation that the stationkeeping ability of needed eNB changes can take place, for example in the chain of command position fixing process, intra-MME inter-eNB (in the MME between eNB) takes place and switches in UE.Then, can further include in force:

When intra-MME inter-eNB switching took place in the chain of command position fixing process, MME received the message that TargeteNB sends, and carried notice in the described message and switched.

In concrete the enforcement, Target eNB sends PATH SWITCH REQUEST (path conversion request) message, just can know to inform and changed evolved base station after MME receives this message.

Promptly, when intra-MME inter-eNB switching takes place in the chain of command position fixing process, after switching is finished, target eNB can send PATH SWITCH REQUEST message to MME and inform that UE has changed the sub-district, MME determines the target eNB stationkeeping ability according to canned data subsequently, and with the stationkeeping ability notice E-SMLC of target eNB.

After switching,, can further include in concrete the enforcement in order to guarantee the stationkeeping ability of MME understand target base station:

Step 901, chain of command position fixing process;

Step 902, source eNB send handover Request (handoff request) to target eNB;

Source eNB switches to Target cell if target eNB is permitted UE after target eNB sends handoff request, then carry out follow-up handover operation, and UE is switched into target eNB, and then target eNB becomes the current service eNB of UE, otherwise does not allow to switch;

Step 903, UE carry out corresponding changeover program and switch to target eNB;

Step 904, target eNB send PATH SWITCH REQUEST message to MME;

Behind Target cell, send PATH SWITCHREQUEST message to MME at the UE successful switch, inform that UE has changed the sub-district by target eNB;

Step 905, MME basis canned data are determined the target eNB stationkeeping ability;

Step 906, MME send update message to E-SMLC;

In this step, MME sends update message to E-SMLC, informs target eNB after switching and the stationkeeping ability of this eNB.For saving the signaling size, can also arrange between MME and the E-SMLC, if the eNB stationkeeping ability changes to some extent, carry the target eNB stationkeeping ability in the update message, if do not carry the eNB stationkeeping ability in the update message, then E-SMLC continues to use original eNB stationkeeping ability;

Step 907, E-SMLC are according to the update message decision subsequent operation that receives (as whether initiating position fixing process etc. again).

In the enforcement, in position fixing process, inter-MME (between MME) also may occur and switch, so, switch if inter-MME takes place UE, old MME can send location abort (end the location) message to E-SMLC and stop current position fixing process.If desired, follow-uply can restart position fixing process by MME or GMLC after switching, wherein eNB stationkeeping ability advice method can be with reference to embodiment shown in Figure 8.Then, can further include in force:

When the inter-MME switching took place in position fixing process, the MME notice E-SMLC before switching stopped current position fixing process.

In concrete the enforcement, can be that the MME before switching stops current position fixing process by send location abort message informing E-SMLC to E-SMLC.

, can further include in the enforcement need restart position fixing process by MME after switching or GMLC the time when follow-up:

When the inter-MME switching takes place, restart position fixing process by MME or GMLC after switching in position fixing process.

2, user's face positioning flow.

In user's face positioning flow, with the query requests of introducing according to E-SMLC, the execution mode of the stationkeeping ability of the service eNB that MME is current with UE notice E-SMLC.

In the enforcement, in user's face position fixing process, at first MME receives the stationkeeping ability query messages that E-SMLC sends, carry E-CGI (the EvolvedCell Global Identifier of sub-district, the current place of UE in the described stationkeeping ability query messages, the cellular global identity of evolution) and TAC (tracking Area Code, Tracking Area Code), the E-CGI of described sub-district and TAC are notified to E-SMLC after user's face locating platform SLP obtains in user's face location sessions SUPL session;

MME determines according to the E-CGI and the TAC of described sub-district whether the current service eNB of this UE is subordinate's eNB then;

If, the stationkeeping ability of in the stationkeeping ability of MME subordinate's eNB, determining the service eNB that this UE is current then according to the E-CGI and the TAC of described sub-district, if not, then find MME under the sub-district, UE place, obtain the stationkeeping ability information of eNB under the sub-district, the current place of UE alternately with this MME by its sub-district E-CGI and TAC;
