Description
Technical field
The present invention relates to the communications field is and in particular to obtain the method for terminal location, end in a kind of WiFi network
End, LTE communication equipment and system.
Background technology
WiFi (Wireless Fidelity), be one kind can by PC, handheld device (as Pad,
Mobile phone) etc. the technology that wirelessly interconnects of terminal.WiFi is the product of a Wi-Fi communication technology
Board, is held by WiFi alliance (Wi-FiAlliance).Purpose is to improve based on IEEE802.11 standard
Intercommunity between Wi-Fi product.
WiFi is originally the abbreviation of Wireless Fidelity, and WiFi English full name is Wireless Fidelity, wireless
The category of LAN refers to " Wireless Fidelity ", substantially a kind of commercial verification, is also a kind of simultaneously
Wireless networking technologies, are networked by radio wave；Common is exactly a wireless router, then at this
The effective range that the electric wave of individual wireless router covers can be networked using WiFi connected mode, if
Wireless router is connected to an adsl line or other online circuit, then be otherwise known as " focus ".
The topmost advantage of WiFi is not need to connect up, and can not be limited by wiring condition, therefore be especially suitable for
The needs of mobile office user, and because transmission signal power is less than 100mw, less than mobile phone transmission power,
So WiFi online is also safety and Health relatively.
Due to WiFi frequency range worldwide need not any telecom operation license, therefore WLAN is no
Line equipment provides and can use in a world wide, expense is extremely cheap and data bandwidth is high nothing
Line air interface.
LTE network is the evolution of 3G network, and under 2G/3G network, speech business is mainly mobile terminal
In CS domain (circuit hosting domain) upper realization, and under LTE 4G network, only ps domain (data field),
There is no CS domain.Therefore, LTE mobile terminal needs using the VoLTE (LTE speech business) based on ps domain
Technology, realizes based on the speech business under LTE 4G network.
Come out with the terminal supporting VoWiFi (WiFi speech business) business, VoWiFi is as VoLTE's
Supplement, the intercommunication of VoWiFi and VoLTE has become the development trend of speech business instantly.
The intercommunication of VoWiFi and VoLTE, it then follows 3GPP (3rd Generation Partnership Project,
Third generation partner program) 3GPP that formulates and non-3 gpp interoperability standard.Its network architecture such as Fig. 1
Shown, wherein contain following equipment/network element：
UE(User Equipment):User equipment.Access WiFi/LTE network, access VoWiFi/VoLTE
Business.
E-UTRAN(Evolved UTRAN)：The Universal Mobile Telecommunications System land radio access web of evolution, that is,
Mobile communication wireless network in LTE.
MME (Mobility Management Entity, mobile management entity)：Chain of command functional entity, faces
When storage user data server, be responsible for and store UE context (such as UE/ ID,
Mobility management states, user security parameters etc.), be user's distribution temporary mark, when UE quarter at this with
Track region or this network are responsible for this user is authenticated；Process all non-access between MME and UE
Layer message.
HSS(Home Subscriber Server):Home subscriber server, permanently stores user contracting data.
Serving GW (Gateway), namely SGW：Gateway, this gateway is a user entity,
Responsible user face data route processing.Management and carrying (bearer) context of storage UE, such as IP holds
Carry service parameter and network internal routing iinformation etc..It is the anchor point in 3GPP system internal user face, a user
Can only there is a Serving GW a moment；
PDN GW (Packet Data Network Gateway), namely PGW：Packet data network gateway, bears
Duty UE accesses the gateway of PDN, and distributing user IP address, is 3GPP and non-3 GPP access system simultaneously
Mobility anchor point.User has access to multiple PDN GW in synchronization.
PCRF(Policy and Charging Rule Functionality)："Policy and Charging Rules Function
Entity, mainly the configuration information according to business information and user signing contract information and operator produces this functional entity
Raw Qos (Quality of Service, service quality) rule controlling user data delivery and charging regulation.
This functional entity can also control the foundation carrying in access network and release.
WLAN(Wireless Local Area Network)：WLAN.The access network of VoWiFi business
Network.3GPP AAA Server(3GPP Authentication、Authorization、Accounting
Server)：3GPP authentication and authorization charging server, is responsible for the certification to UE and signing.
ePDG(Evolved Packet Data Gateway)：The packet data gateway of evolution, this gateway right and wrong
The access gateway of 3GPP (WLAN) and 3GPP interoperability.The UE accessing from WLAN, by ePDG to 3GPP
AAA Server is authenticated and contracts, and accesses PDN GW by ePDG, further using LTE core
The resource of net.
IMS(IP Multimedia Subsystem)：Internet protocol multimedia subsystem, is 3GPP (Third
Generation Partnership Project, third generation partner program) the many matchmakers of support IP that propose
The subsystem of body business, it is noteworthy characterized by and employs SIP (Session Initial Protocol, session
Initiation protocol) system, communication is unrelated with access way, possesses the control function of multiple multimedia services and holds
Loading capability separates, calling is separated with session, apply separate with service, business is separated with network, and mobile
Net and the multi abilities such as internet service fusion.
In LTE network, during carrying out VoLTE business, the positional information of terminal can be reported MME by base station,
MME further by reporting position to SGW, positional information is reported PGW by SGW, and positional information is reported by PGW
To PCRF, IMS obtains from PCRF again, implements the business such as number completion according further to this positional information.So
And, when UE is attached to wlan network it is impossible to carry the positional information of user, when carrying out VoWiFi business,
These LTE communication equipment of PDN GW, PCRF, IMS in LTE network cannot obtain the positional information of terminal,
Result in the need for the related application of terminal positional information, the such as application such as number completion cannot be implemented.
