Description

Positioning service in long-term evolution network implementation method and system
Technical field
The present invention relates to moving communicating field, relate more specifically to positioning service implementation method and system in LTE.
Background technology
At present mobile communication technology is faced with provides higher data rate, provides the problem of better covering and larger capacity for network for user.
In order to address the above problem, 3GPP (3rd Generation Partnership Project, third generation partner program) in December, 2004, started wireless access network Long Term Evolution project LTE, access technology E-UTRA (the Evolved-UTRA of evolution, the UTRA of evolution) and the access network E-UTRAN (Evolved-UTRAN of evolution, the UTRAN of evolution), and towards the packet domain core network evolution items SAE of all-IP, wish by evolve and enhancing from wave point to core network, for operator and the ever-increasing demand of user provide better support, 10 years from now on even longer time, remain on the technology first-strike advantage of moving communicating field always.
Access layer information refers to can be at access device, for example terminal and base station side, between the message directly processed, the relevant message of radio resource control RRC for example, non-access layer information refers to be transferred to the message that core-network side is processed.Because equipment of the core network and terminal equipment do not have direct interface, in LTE, terminal is transmitted the message of Non-Access Stratum by " ULInformationTransfer " message of RRC protocol layer.UE is filled into the message content that need to be transferred to core net in ULInformationTransfer message field, by RRC agreement, ULInformationTransfer message is sent to base station, then by base station, passes to core net.When core net receives after ULInformationTransfer, according to the information type sign of this message the inside, judge, if the non-access layer information of current system, with regard to being given to the protocol layer of the relevant Non-Access Stratum of network, process, if other system, for example current system is LTE (LongTerm Evolution, Long Term Evolution project), the system of CDMA2000 just belongs to other system so, is just given to other system and processes.
Positioning service (LCS, LoCation Services) is a kind of novel value-added service that mobile radio communication provides.This business obtains the positional information (longitude and latitude, translational speed etc.) of travelling carriage by wireless location technology, offer user, mobile communication network or other external entity, realizes the various business relevant to position.
Terminal can be passed through the measurement to Serving cell or neighbor cell, or by built-in locating module, satellite-signal is measured, to obtain for calculating the data of this terminal current location.For support location service, on the basis of LTE prior art, introduced new agreement: location protocol LPP (LTEPositioning Protocol, LTE location protocol).Exist at present two kinds of possible LPP host-host protocol frameworks all to relate to location protocol unit, LPP1, refers to the location protocol unit transmitting between terminal and base station as shown in Figure 1.According to current requirement, this agreement also needs, by the ULInformationTransfer message of RRC (RadioResource Control, Radio Resource is controlled) agreement, by terminal transmission relevant information, to send to base station.
Because LPP is two message between access device, do not belong to non-access layer information, do not belong to other system message yet.According to current ULInformationTransfer message parse above, when location protocol unit need to transmit in ULInformationTransfer, according to prior art, cannot process.

Embodiment
The main thought of positioning service implementation method of the present invention and system is that terminal is sent locating information and indicates this information type to network side by UL information transfer message, so that network side can correctly resolve and process.
Positioning service implementation method of the present invention, as shown in Figure 2, comprising:
Step 201: terminal sends UL information transfer message to eNB (Evolved NodeB, evolution base station), wherein carries locating information and type indication information, and described type indication information is used to indicate described locating information for positioning service;
According to network location request or position fixing process, as needs such as location surveys, UE need to provide, feed back locating information to network; UE is packaged into location protocol data cell LPP PDU by locating information and LPP PDU is encapsulated in UL information transfer message ULInformationTransfer, and type indication information embodies by protocol fields or information type.
Step 202: described evolution base station eNB receives described UL information transfer message ULInformationTransfer, according to described type indication information identify described locating information for positioning service after, according to described locating information, position Business Processing.
Terminal sends ULInformationTransfer message to eNB by Dedicated Control Channel, eNB receives after ULInformationTransfer, judgement protocol Data Unit PDU is wherein for positioning service, and the location protocol data cell of transmitting in this message is processed to location protocol layer.
In LTE, in order to support location, introduce location protocol LPP.The framework map that may adopt from transmission LPP agreement discussed above is seen, needs transmitting location protocol unit between UE and E-UTRAN.From the overall angle of LTE compressed structure, reduction complexity, should utilize as much as possible existing protocol message to transmit LPP PDU.Consider in the RRC agreement of current LTE, UL information transfer message ULInformationTransfer, be mainly used in UE and transmit Non-Access Stratum, CDMA2000 information to E-UTRAN, can expand this message, for UE, transmit the LPP PDU of location protocol unit to E-UTRAN.
