Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure. One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.
Furthermore, the drawings are only schematic illustrations of the present disclosure, in which the same reference numerals denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.
The terms involved in the embodiments of the present disclosure are explained as follows:
(1) CSCF: call Session Control Function call session control, the function is a functional entity inside the IP multimedia subsystem (IP Multimedia Subsystem, IMS), which is the core of the whole IMS network and is mainly responsible for handling signaling control during the multimedia call session. It manages user authentication of the IMS network, IMS (IP Multimedia Subsystem ) bearer plane QoS (Quality of Service, quality of service), control of SIP sessions in cooperation with other network entities, and service negotiation and resource allocation, etc. The CSCFs are classified into Proxy CSCFs (P-CSCFs) according to functions, query CSCFs (Interrogating CSCF, I-CSCFs) and Serving CSCFs (S-CSCFs) according to functions, and the like.
(2) The P-CSCF (Proxy-CSCF) is a unified entry point to the IMS visited network. All session messages initiated and terminated by the IMS terminal pass through the P-CSCF. The P-CSCF is used as a SIP Proxy and is responsible for user authentication and IPSec management which are irrelevant to an access network, network anti-attack and security protection, SIP signaling compression and decompression are carried out for saving wireless network resources, roaming control of a user is carried out through PDF (Policy Decision Function), and the functions of NAT (Network Address Translation), qoS and the like of a bearing surface are carried out.
(3) 3GPP:3rd Generation Partnership Project, third generation partnership project organization (PCG), in the organization of 3GPP, is the highest authority responsible for overall coordination work on behalf of OPs, such as for 3GPP organization architecture, time planning, work allocation, etc. The work in the technical field is done by the Technical Specification Group (TSG). Currently, 3GPP is divided into 3 TSGs, which are respectively TSG RAN (radio access network), TSG SA (service and system), and TSG CT (core network and terminal). Each TSG is divided into a plurality of Working Groups (WGs), each WG respectively undertaking a specific task, and currently there are 16 WGs. Such as TSG RANs, are divided into 6 working groups, RAN WG1 (radio layer 1), RAN WG2 (radio layer 2 and layer 3), RAN WG3 (radio network architecture and interface), RAN WG4 (radio frequency performance), RAN WG5 (terminal conformance test) and RAN WG6 (GERAN radio protocol).
(4) RAR: when the UE transmits a Preamble, it is not immediately ready to receive the RAR (Random Access Response ) message, but starts to receive the RAR message after the 3rd subframe after transmitting the Preamble. Of course, it is also not possible for the UE to wait for the RAR all the time, and if the UE continuously detects ra-ResponseWindowSize (response receiving window size) subframes still not receiving the RAR, the UE does not continue to monitor the RAR information.
(5) TAI: tracking Area Identity tracking area identity, tai=plmn+ TAC (Tracking Area Code), and a plurality of TAs form a TA List, and are simultaneously allocated to a UE, where the UE does not need to perform TA update when moving in the TA List (TA List), so as to reduce frequent interaction with the network. When the UE enters a new TA area that is not in the TA list that it registers, it needs to perform TA update, and the MME reallocates a set of TAs to the UE, where the newly allocated TAs may also include some TAs in the original TA list, and each cell only belongs to one TA.
(6) ECGI: E-UTRAN Cell Global Identifier E-UTRAN, cell Global identifier, ECGI consists of PLMN+Cell Identity, for globally identifying a Cell in the PLMN. Cell Identity (Cell Identity) consists of enodebid+cell ID. Which contains 28bits of information, the first 20bits representing the enodebs ID and the last 8bits representing the Cell ID. ECGI (non more than 52 bits) =plmn id+eci.
(7) PLMN: public Land Mobile Network public land mobile network, network identity established and operated for the purpose of providing land mobile services to the public by government or its approved operators, plmn=mcc (Mobile Country Code ) +mnc (Mobile Network Code, mobile network code).
For example, the U.S. MCCs have 310, 311 and 316, and the China MCC has only 460.
For example, the MNC of chinese movement is 00, the MNC of chinese communication is 01, the MNC of chinese communication CDMA is 03, and the MNC of chinese satellite full ball star network is 04.
For example, the PLMN for chinese mobile is 46000 and the PLMN for chinese communication is 46001.
(8) TAC: tracking Area Code a Tracking Area code is used to define a Tracking Area code to which a cell belongs, where one Tracking Area may cover one or more cells, typically 16bits, and a Tracking Area (Tracking Area) is a new concept set up by the LTE system for location management of UEs. When the UE is in an idle state, the core network can know the tracking area where the UE is located, and when the UE in the idle state needs to be paged, paging must be performed in all cells of the tracking area where the UE is registered.
(9) ECI: E-UTRAN Cell Identifier, evolved universal terrestrial radio access network Cell identity, ECI (28 Bits) =eNB ID (20 Bits) +Cell ID (8 Bits), and 16Bits are changed to 7 Bits total ECI, 5 Bits eNB ID and 2Bits Cell ID. For example: the conversion of Scell ID 80682509 to normal enodebs ID and CI,80682509 to 16 is 4CF1E0D, i.e., eNB ID corresponds to 4CF1E and cell ID corresponds to 0D.
FIG. 1 shows a schematic diagram of an exemplary system architecture to which a positioning method or positioning device of an embodiment of the invention may be applied.

The user may interact with the server 105 via the network 104 using the terminal devices 101, 102, 103 to receive or send messages or the like. The terminal devices 101, 102, 103 may be various electronic devices with display screens including, but not limited to, smartphones, tablet computers, portable computers, desktop computers, and the like.
The server 105 may be a server providing various services. For example, the user may obtain, by using the terminal device 103 (may also be the terminal device 101 or 102), a positioning time period and a time threshold for determining a position by searching for a satellite each time from the server 105, and perform positioning according to the positioning time period and the time threshold for determining a position by searching for a satellite each time, calculate the number of times of incomplete positioning, where the number of times of incomplete positioning includes the number of times of incomplete positioning within a range of the time threshold for determining a position by searching for a satellite each time, and switch the operating state of the satellite positioning module according to the number of times of incomplete positioning, so that missing positioning information may be avoided, thereby improving positioning accuracy.
In some embodiments, the positioning method provided by the embodiments of the present invention is generally performed by the terminal 105, and accordingly, the positioning device is generally disposed in the terminal 103 (may also be the terminal 101 or 102). In other embodiments, some servers may have similar functionality as the terminal device to perform the method. Therefore, the positioning method provided by the embodiment of the invention is not limited to be executed by the terminal equipment.
