Description

Special-purpose S1 signaling connects method, system and the equipment of setting up and positioning

Technical field

The present invention relates to wireless communication technology field, particularly a kind of special-purpose S1 signaling connects method, system and the equipment of setting up and positioning.

Background technology

In LTE (Long Term Evolution, Long Term Evolution) system, support chain of command location and user plane location.The network side server of chain of command location is E-SMLC (Enhanced Serving Mobile Location Centre; The shift position service centre that strengthens); Location protocol between UE (subscriber equipment) and the E-SMLC is LPP (LTE Positioning Protocol, a Long Term Evolution location protocol).

LPP is the point-to-point protocol between location-server and target device, is used for locating the position of certain target device.LPP can be applied to the chain of command location, also can be applied to the user plane location.When being applied to the chain of command location, target device is UE, and server is E-SMLC.

In the LTE system, the method for multiple positioning UE is provided, like OTDOA (Observed Time Difference OfArrival, descending arrival time observation is poor).

Definite UE position of time difference that the OTDOA localization method arrives through detecting 3 different base station signals.Shown in Figure 1A,

The coordinate of supposing terminal UE for (x, y), the position coordinates of base station i be (xi, yi), the time of base station i transmission signal is Ti, the time that UE receives this signal is τ _iCan get by base station i:

${\mathrm{\τ}}_i-T_i=\frac{\sqrt{{(x-x_i)}^2+{(y-y_i)}^2}}{c};$

Therefore can get equation by base station 1 and the time difference that base station 2 arrives UE:

${\mathrm{\τ}}_2-{\mathrm{\τ}}_1=(T_2-T_1)+\frac{\sqrt{{(x-x_2)}^2+{(y-y_2)}^2}-\sqrt{{(x-x_1)}^2+{(y-y_1)}^2}}{c};$

This is a Hyperbolic Equation (saying accurately, is a curve's equation in the hyperbola), needs plural hyperbola curvilinear equation, two two-dimensional position coordinates that hyp intersection point is UE in order to confirm the UE position.With sub-district as a reference, base station 1, then can get equation group:

$\left\{\begin{array}{c}{\mathrm{\τ}}_2-{\mathrm{\τ}}_1=(T_2-T_1)+\frac{\sqrt{{(x-x_2)}^2+{(y-y_2)}^2}-\sqrt{{(x-x_1)}^2+{(y-y_1)}^2}}{c}\\ {\mathrm{\τ}}_3-{\mathrm{\τ}}_1=(T_3-T_1)+\frac{\sqrt{{(x-x_3)}^2+{(y-y_3)}^2}-\sqrt{{(x-x_1)}^2+{(y-y_1)}^2}}{c}\end{array}\right.;$

Separate this equation group get final product the two-dimentional geographical coordinate of UE.Wherein c is the light velocity.Poor (the T of base station transmitting time _i-T ₁) and the position coordinates of each base station as auxiliary data; By OAM (Operations, Administrationand Maintenance; Operations, Administration and Maintenance) equipment directly disposes and gives E-SMLC; If need dynamically update, E-SMLC can be through obtaining these auxiliary data informations with inter-base station interface.In order to obtain accurate location, the OTDOA method requires to have simultaneously the base station more than three to participate in the measurement of positional parameter RSTD (Reference Signal Time Difference, reference signal time difference).Consider that UE directly detects the possibly positioning accuracy that can't reach expection of descending public reference signal of adjacent base station; Introduced PRS (Positioning Reference Signals in the LTE system; Location reference signals), be exclusively used in UE measurement base station signal in the OTDOA localization method.The scheme of the PRS sub-frame configuration of each measurement cell of E-SMLC acquisition is the same with other auxiliary datas, generally directly disposes through OAM.And UE can obtain the PRS sub-frame configuration of measurement cell collection through the auxiliary data transmission function of LPP from E-SMLC in the OTDOA position fixing process.

In the OTDOA method, monitor the pilot signal of a plurality of base stations simultaneously, obtain the time difference that signal arrives between the base station, thereby obtain plural Hyperbolic Equation, confirm the position of UE through UE.Consider that it possibly performance not be very good that UE uses the adjacent base station signal of the descending detection of public reference signal, introduced PRS in the LTE system, be exclusively used in UE measurement base station signal in the OTDOA localization method.The method of the OTDOA of agreement support at present is based on E-SMLC's, and promptly UE carries out the measurement of the observed time difference of many sub-districts, and measurement result is reported E-SMLC through the LPP agreement, does position calculation by E-SMLC.

In order to accomplish the OTDOA location; E-SMLC need know the geographical position coordinates of measured base station in advance; And the PRS of measured base station configuration (wherein, PRS is configured in the follow-up terminal positioning process and sends to UE as auxiliary data, and auxiliary UE carries out the required measurement in OTDOA location).These information can directly dispose in advance through OAM and give E-SMLC.

The OTDOA localization method that UE is auxiliary is only supported in the OTDOA location at present.And from the initiator of Location Request, the location is divided into MO-LR (being own position, UE request location), MT-LR (position of certain UE is located in outside LCS client request) and NI-LR (network initiates to locate the position of certain UE automatically, like urgent call) again.Wherein, MO-LR is the Location Request that UE triggers, the Location Request that MT-LR and NI-LR trigger for the EPC side.Below, be example with MO-LR, the positioning flow of OTDOA is carried out brief account.

Shown in Figure 1B, the scheme of UE triggered location request comprises:

Step 0: if UE is in idle (free time) state, then UE sets up the connection of NAS (Non Access Stratum, Non-Access Stratum) signaling, and for the UE that is in connection status, this step can be omitted;

Step 1:UE initiates a Location Request, the positional information of acquisition request self through NAS layer message to MME (Mobility Management Entity, Mobility Management Entity);

Step 2:MME initiates Location Request to E-SMLC;

Step 3:E-SMLC selects to adopt the OTDOA localization method;

Step 4a～step 4b:E-SMLC inquires about and obtains the stationkeeping ability information of UE;

Step 5:E-SMLC provides auxiliary data message through LPP.Possibly comprise following information in the auxiliary data message that LPP provides:

1. the information of reference cell comprises the information such as PCI, E-CGI, frequency, PRS configuration of reference cell, and the reference cell of choosing is not limited to Serving cell;

2. information of adjacent cells tabulation comprises the information such as PCI, E-CGI, frequency, PRS configuration of each adjacent sub-district.Information of adjacent cells tabulation is to be beneficial to the adjacent sub-district of measurement according to some that in advance estimation of UE position is chosen;

The positional information of step 6a～step 6b:E-SMLC request and acquisition UE mainly comprises relevant measurement result;

Step 7:E-SMLC calculates the positional information of UE according to measurement result and the input of other each side of UE;

Step 8:E-SMLC issues MME with positioning result (positional information);

Step 9:MME issues UE with positioning result (positional information) through NAS layer message.

In the LTE system, introduced HeNB (Home eNode B, Home eNodeB) node and carried out the focus covering.Generally HeNB is the node that user oneself disposes, and it provides wireless network access function (similar with eNB) for UE.Because HeNB is disposed by user oneself, so the deployed position of HeNB can't be known by operator at present, this has caused difficulty for following function is provided:

A) network planning: if confirmed the position of HeNB, operator can be through the working frequency points of configuration HeNB, and the transmitting power of restriction HeNB avoids HeNB to cause big interference for eNB or adjacent HeNB;

B) UE location: cordless communication network is to know the position for the UE serving base station to the prerequisite of the location of UE.If can not obtain the position of HeNB, the UE to this HeNB service positions and can't accomplish so.

UE OTDOA positioning flow can not directly be used for the location of HeNB at present.This be because:

HeNB is as eNB, and it does not have special-purpose S1 signaling to connect, so even it has supported location protocol, the localization message corresponding with HeNB also can't transmit between HeNB and MME.

In sum, HeNB can't set up special-purpose S1 signaling connection at present.

The S1 interface is the logic interfacing of setting up between wireless access network node and core net node, specifically is divided into chain of command interface (S1-MME) and interface in the user plane (S1-U) again.S1-MME is the logic interfacing of setting up between wireless access network node and the MME, is used to transmit chain of command signaling (the signaling particular content is referring to 3GPPTS36.413).S1-U is the logic interfacing of setting up between wireless access network node and the SGW, is used for transmission user face data (the user face data packet format is referring to 3GPP TS29.281).

The S1 signaling is the signaling of on S1-MME interface, transmitting, and is used for transmitting control information between eNB and MME, comprising: the control information that UE is relevant: comprise the foundation of UE carrying, modification and release etc.; The control information that UE is irrelevant: comprise interface foundation, processes such as overload indication.

Below in conjunction with Figure of description the embodiment of the invention is described in further detail.

In the declarative procedure below; Implement to describe from the cooperation of network side and user equipment side earlier; Describe from the enforcement of network side and user equipment side respectively at last; But this does not also mean that the two must cooperate enforcement; In fact, separate when implementing, also solved respectively in network side, the existing problem of user equipment side when network side and user equipment side; When just the two is used in combination, can obtain better technique effect.

As shown in Figure 2, the method for the special-purpose S1 signaling connection of embodiment of the invention foundation comprises the following steps:

Step 201, first network equipment are confirmed to set up special-purpose S1 signaling and are connected;

Step 202, first network equipment send the S1 signaling connection that comprises the first network equipment S1AP (S1 Application protocol, S1 Application Protocol) sign to second network equipment and set up request message;

Step 203, second network equipment receive from the S1 signaling connection that comprises first network equipment S1AP sign of first network equipment and set up request message;

Step 204, second network equipment be in that confirm can be with after first network equipment be set up special-purpose S1 signaling and is connected, sends to first network equipment to comprise the S1 signaling connection establishment response message that first network equipment S1AP sign and the second network equipment S1AP identify;

Wherein, if first network equipment is HeNB, then second network equipment is MME;

If first network equipment is MME, then second network equipment is HeNB.

In force, pass through S1-MME interface pass-along message between first network equipment and second network equipment.

Wherein, it is multiple that the embodiment of the invention is set up the scheme that special-purpose S1 signaling connects, and enumerates several below.

Scheme one, first network equipment are MME, and second network equipment is HeNB; Through NAS layer Signalling exchange, set up special-purpose S1 signaling and connect.

Concrete, also comprise before the step 201:

HeNB sends the S1AP sign that comprises HeNB and the S1AP message of NAS request message to MME when needs are set up special-purpose S1 signaling and connected.

Preferably, HeNB generates the NAS request message, is used to indicate MME to hope to set up special-purpose S1 signaling and connects, and this NAS message can include but not limited at least a in the following message:

1, message identifier: the type/purpose of indicating this message;

2, HeNB identification information: the ID of HeNB for example; When MME had connected a plurality of HeNB, the NAS layer of MME can be distinguished different HeNB according to HeNB ID.

Simultaneously, in order to transmit above-mentioned NAS request message, need to generate the S1-AP request message and be used to carry the NAS signaling packet.This S1AP message can adopt existing message, like INITIAL UE MESSAGE, also can define new S1AP message, and S1AP message can include but not limited at least a in the following message:

1, message identifier: the type/purpose of indicating this message;

2, eNB S1AP ID:HeNB is that oneself distributes, and is used for the ownership that on S1-MME interface, connects at HeNB side sign dedicated signaling;

3, NAS-PDU: content is above-mentioned NAS request message.

HeNB sends to corresponding MME with the S1AP message that generates from S1-MME interface.Be used to trigger special-purpose S1 signaling establishment of connection.

Accordingly, in the step 201, after MME receives S1AP message, obtain the NAS request package in this message; According to the indication of NAS request package, confirm to set up special-purpose S1 signaling and connect;

In the step 202, MME generates and sends special-purpose S1 signaling and connects and set up request message, and the S1 signaling connects to be set up request message and can include but not limited at least a in the following message:

1, message identifier: the type/purpose of indicating this message;

2, MME S1AP ID: by MME is that HeNB distributes, and is used for the ownership that connects at the MME of S1-MME interface one side sign dedicated signaling;

3, the eNB S1AP ID in the eNB S1AP ID:S1AP message.

In the step 203, HeNB receives the S1 signaling and connects and sets up request message: in this message, set up special-purpose S1 signaling between MME request and the HeNB and is connected, request message is set up in the connection of S1 signaling can include but not limited at least a in the following message:

1, message identifier: the type/purpose of indicating this message;

2, MME S1AP ID: by MME is that HeNB distributes, and is used for the ownership that connects at the MME of S1-MME interface one side sign dedicated signaling;

3, eNB S1AP ID: distribute by HeNB, can know that according to this sign HeNB it is be directed against which UE/HeNB's that special-purpose S1 signaling that the MME expectation is set up connects.

In the step 204, if HeNB can accept, then send S1 signaling connection establishment response message and give MME, S1 signaling connection establishment response message can include but not limited at least a in the following message:

1, message identifier: the type/purpose of indicating this message;

2, the connection of MME S1AP ID:S1 signaling is set up in the request message;

3, the connection of eNB S1AP ID:S1 signaling is set up in the request message.

MME receives the special-purpose S1 signaling connection establishment response message that HeNB sends, and obtains and preserve MME S1AP ID and eNB S1AP ID in this message.

Preferably, can further include after the step 204:

Set up successfully if special-purpose S1 signaling connects, MME sends the NAS response message to HeNB, and this message can be carried in the descending direct-sending message of S1AP; The NAS response message can include but not limited at least a in the following message;

1, message identifier: the type/purpose of indicating this message;

2, HeNB identification information: the ID of HeNB for example;

Accordingly, HeNB receives the NAS response message of the NAS layer that is used to notify HeNB, confirms that special-purpose S1-AP connects to set up successfully.

In scheme one, if having HeNB GW between HeNB and the MME, then can shine the regulation (specifically can referring to 3GPP TS 36.300 agreements) of existing protocol,, transmit then and get final product through the S1AP ID in the S1 message of its transfer by HeNB GW replacement.That is to say,, do not influence other nodes (HeNB, MME, behavior E-SMLC) of regulation in the scheme one no matter whether HeNB GW exists; Do not influence the HeNB GW behavior of stipulating in the existing protocol yet.

Scheme two, first network equipment are HeNB, and second network equipment is MME; Mutual through S1-AP, UE (or HeNB) related news trigger sets up special-purpose S1 signaling connection.

Concrete, in the step 202, HeNB generates and is used to trigger special-purpose S1 signaling and connects the S1 signaling of setting up and connect and set up request message, and this S1 signaling connects to be set up request message and can include but not limited at least a in the following message:

1, message identifier: the type/purpose of indicating this message;

2, eNB S1AP ID:HeNB is that oneself distributes, and is used for the ownership that on S1-MME interface, connects at HeNB side sign dedicated signaling;

Preferably, can also carry the HeNB sign: when HeNB linked MME through HeNB GW, this HeNB sign can help MME to confirm that which HeNB need set up special-purpose S1 signaling and connect; When HeNB directly linked MME, HeNB can select to carry or do not carry this sign, because when HeNB and MME initially set up the S1 interface, HeNB had reported the identification information of oneself.Which S1 MME connects from according to received message, promptly knows the sign of opposite end HeNB.

Accordingly; In the step 204; MME obtains the connection of S1 signaling and sets up message identifier and the eNB S1AP ID in the request message; And according to the indication of S1-AP request message; Distribute MME S1AP ID; Setting up special-purpose S1 signaling connects: generate and send S1 signaling connection establishment response message, the MME side is preserved the corresponding relation of ID to (MME S1AP ID and eNB S1AP ID) and HeNB ID, and this S1 signaling connection establishment response message can include but not limited at least a in the following message:

1, message identifier: the type/purpose of indicating this message;

2, MME S1AP ID: by MME is that HeNB distributes, the ownership that is used for connecting at the MME of S1-MME interface one side sign dedicated signaling (only set up success message comprise);

3, eNB S1AP ID: this sign is in a last step, is distributed by HeNB, and according to this sign, HeNB can know it is to which UE/HeNB's that special-purpose S1 signaling that the MME expectation is set up connects.

HeNB receives S1 signaling connection establishment response message.

In scheme one, if having HeNB GW between HeNB and the MME, then can shine the regulation (specifically can referring to 3GPP TS 36.300 agreements) of existing protocol,, transmit then and get final product through the S1AP ID in the S1 message of its transfer by HeNB GW replacement.That is to say,, do not influence other nodes (HeNB, MME, behavior E-SMLC) of regulation in the scheme one no matter whether HeNB GW exists; Do not influence the HeNB GW behavior of stipulating in the existing protocol yet.

Scheme three, first network equipment are MME, and second network equipment is HeNB; Carry out alternately through S1AP, UE (or HeNB) irrelevant messages triggers sets up special-purpose S1 signaling connection.After the eNB start, set up the S1 interface between needs and the MME.This interface is not set up for some UE, sets up for guaranteeing the eNB operate as normal, is called the UE irrelevant messages.

Concrete, also comprise before the step 201:

HeNB is when needs are set up special-purpose S1 signaling and connected; Be used to indicate MME to hope to set up the S1AP message that special-purpose S1 signaling connects to the MME transmission, this S1AP message is the irrelevant S1AP message of UE (HeNB), can adopt existing message; Like S1SETUP REQUEST, also can define new S1-AP message;

This message can include but not limited at least a in the following message:

1, message identifier: the type/purpose of indicating this message;

2, HeNB identification information: the ID of HeNB for example;

3, S1 signaling connection type indication: indicate this message to be used between (H) eNB and MME, setting up the S1 interface or connect for HeNB oneself sets up special-purpose S1 signaling; For example: judge through whether carrying this indication information; Carry expression and set up the S1 interface, do not carry expression and set up special-purpose S1 signaling connection; Or the content through this indication information judges that the S1 interface is set up in " Non UE-associated " expression, and " UE (HeNB)-associated " expression is set up special-purpose S1 signaling and connected, and " both " expressions are set up the S1 interface simultaneously and are connected with special-purpose S1 signaling.

HeNB sends to corresponding MME with the S1AP message that generates.Be used to trigger special-purpose S1 signaling establishment of connection.

After MME receives S1AP message, obtain message identifier, HeNB identification information (which HeNB is used for confirming specifically is) and the indication of S1 signaling connection type in this message.Hope to set up special-purpose S1 signaling connection when S1 signaling connection type is designated as HeNB, set up the carrying of S1AP dedicated signaling if MME allows for this HeNB, then the HeNB to correspondence sends the S1AP request response; This HeNB sets up the carrying of S1AP dedicated signaling or MME does not have distributable resource if MME does not allow for, and then MME returns the S1-AP request failure message, carries failure cause and is " Failure in UE (HeNB)-associated ";

If HeNB receives the S1-AP request response, know that MME allows for oneself to set up special-purpose S1 signaling and connect; If receive the S1-AP request failure message, then special-purpose S1 signaling connects sets up failure.

Accordingly, in the step 202, MME initiates S1AP dedicated signaling loading establishing process: generate also and to send special-purpose S1 signaling to the HeNB of correspondence and connect and set up request message, the S1 signaling connects to be set up request message and can include but not limited at least a in the following message:

1, message identifier: the type/purpose of indicating this message;

2, MME S1AP ID: by MME is that HeNB distributes, and is used for the ownership that connects at the MME of S1-MME interface one side sign dedicated signaling;

3, the eNB S1AP ID in the eNB S1AP ID:S1AP message.

In the step 203, HeNB receives the S1 signaling and connects and sets up request message: in this message, set up special-purpose S1 signaling between MME request and the HeNB and is connected, request message is set up in the connection of S1 signaling can include but not limited at least a in the following message:

1, message identifier: the type/purpose of indicating this message;

2, MME S1AP ID: by MME is that HeNB distributes, and is used for the ownership that connects at the MME of S1-MME interface one side sign dedicated signaling;
