Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Embodiments of the present application are set forth in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.
Spatial relational terms, such as "under," "below," "under," "over," and the like may be used herein to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements or features described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary terms "under" and "under" can encompass both an orientation of above and below. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations) and the spatial descriptors used herein interpreted accordingly.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be connected to the other element through intervening elements. Further, "connection" in the following embodiments is understood to mean "electrical connection", "communication connection", or the like, if there is a transfer of electrical signals or data between the connected objects.
As used herein, the singular forms "a", "an" and "the" may include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises/comprising," "includes" or "including," etc., specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Also, as used in this specification, the term "and/or" includes any and all combinations of the associated listed items.
The AGPS scheme can be divided into two types, namely cp (control plane) and up (user plane), from the bearer mode; the CP refers to a control plane protocol stack, and sends user data into control plane data, where the control plane data may specifically refer to a Non-access stratum (NAS) layer, and has the advantages of fast transmission speed when data is less and no need to establish a third route; UP refers to a user plane protocol stack, user data and control data are separated, and a path is dedicated to walking user data, which has the advantage of fast transmission when there is much data. The slave positioning initiator can be divided into two modes, namely SI (SET Initiated, positioning request Initiated by user) and NI (Network Initiated, positioning request Initiated by server).
However, the conventional AGPS scheme has at least the following drawbacks: AGPS positioning data mainly depends on a network server, and satellite searching positioning is influenced if the data is wrong; the data error may mean that erroneous ephemeris data is provided, which may not only accelerate satellite search and positioning but also affect satellite search and positioning, for example, the AGPS server does not have an accurate base station location database, or outdated data is provided. In addition, in an actual system, the NI-CP type positioning request has a high priority (i.e., the network-initiated positioning request based on air interface signaling has a high priority), which may interrupt other currently ongoing positioning sessions (e.g., network-initiated NI-UP based on data, user-initiated SI-CP based on signaling, pure GPS positioning session, etc.), and may adversely affect the reporting of the location status report, thereby causing the upper layer application to fail to refresh the location in time.
That is, the conventional AGPS scheme has a problem that a base station is configured incorrectly, a terminal cannot use auxiliary data for searching and positioning due to an unsupported positioning mode (e.g., NI-CP), and a base station cannot report a location status report due to a positioning request being issued all the time (it should be noted that the base station issues the positioning request all the time, which is an error condition caused by an abnormal configuration of the base station).
The method and the device provide a satellite positioning request management optimization scheme based on the blacklist and the penalty timer, can effectively avoid the interference of wrong positioning requests on a network side to the terminal, improve the continuity of terminal positioning service, and are better compatible with abnormal environments. In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The satellite positioning method can be applied to AGPS positioning; AGPS is a system that performs positioning by a mobile communication base station based on GPS positioning and performs data transmission using a network. Briefly, AGPS uses a GPS chip of a device and a mobile communication network to achieve positioning. The terminal uses the mobile communication network without leaving the base station, namely, the terminal accesses the mobile communication network through the base station and further establishes connection with the AGPS server.
The basic flow from positioning start to finding available satellites by a GPS receiver in AGPS is as follows: (1) the device obtains the current Cell position from the cellular base station, i.e. one-time COO (Cell of Origin) positioning. (2) The device communicates the current cell location to an AGPS location server in the network through the cellular network. (3) The APGS position server inquires currently available satellite information (including frequency band, azimuth, elevation angle and other relevant information of the satellite) in the area according to the current cell position and returns the information to the equipment. (4) The GPS receiver can quickly find the currently available GPS satellite according to the obtained available satellite information. By this point, the GPS receiver has been able to normally receive GPS signals and the GPS initialization process is complete. The improvement of the positioning speed by AGPS can be embodied in the above process.
It should be noted that the devices referred to in this application are not limited to 5G networks, and include: the system comprises a mobile phone, an Internet of things device, an intelligent household device, an industrial control device, a vehicle device and the like. The Device may also be referred to as a Terminal (Terminal), a Terminal Device (Terminal Device), a Mobile Station (Mobile Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), and a User Equipment (UE), which are not limited herein. The above-mentioned device may also be an automobile in Vehicle-To-Vehicle (V2V) communication, a machine in machine-type communication, or the like.
In addition, the base station referred to in the present application may be a Base Station (BS) device deployed in a radio access network to provide a UE with a wireless communication function, and includes various forms of macro base stations, micro base stations, relay stations, controllers, access points, and the like. In systems using different radio access technologies, names of devices having functions of base stations may be different, for example, in an LTE network, referred to as an evolved node B (eNB), in a third generation 3G network, referred to as a node B (node B), or a communication node applied in a fifth generation communication system, an NR base station, and the like, and other similar network devices may also be used.
The satellite positioning method provided by the application can be suitable for an LTE system, an LTE-Advanced (LTE-A) system or other wireless communication systems adopting various wireless access technologies, such as systems adopting access technologies of code division multiple access, frequency division multiple access, time division multiple access, orthogonal frequency division multiple access, Carrier Aggregation (CA) and the like. Furthermore, it may also be applicable to use of a subsequent evolution system, such as a fifth generation 5G system, etc.
In one embodiment, as shown in fig. 1, a satellite positioning method is provided, which is described by taking the method as an example for a terminal, and includes the following steps:
step 102, receiving a positioning request issued by a network side under the condition of starting positioning, and then determining whether the positioning request meets a preset available condition. The preset available condition comprises that the positioning request comprises available auxiliary positioning information.
In particular, the available assisted positioning information may refer to correct ephemeris data. For example, the available assisted positioning information may include the transmitted position of the terminal and GPS assisted positioning information (including ephemeris and azimuth angle of GPS, etc.) associated with that position. The unavailable auxiliary positioning information may specify that the auxiliary positioning information provided by the bit request contains information errors (including illegal data), such as erroneous ephemeris data, and that the available satellites cannot be successfully searched.
In the application, the terminal may determine whether the auxiliary positioning information is available, and then obtain whether the positioning request includes available auxiliary positioning information or unavailable auxiliary positioning information, determine the positioning request including the available auxiliary positioning information as an available positioning request, and determine the positioning request including the unavailable auxiliary positioning information as an unavailable positioning request. In some embodiments, the terminal may first determine whether the assisted positioning information includes illegal data, such as satellite number, satellite period, satellite elevation angle, etc., which are not within range, and then check whether available satellites can be successfully searched according to the assisted positioning information, thereby determining whether the assisted positioning information is available.
Further, after the terminal starts positioning, if a positioning request issued by the network side is received, it needs to be confirmed whether the positioning request meets a preset available condition; the preset availability condition includes that the positioning request contains available auxiliary positioning information. Therefore, the method and the device can manage and optimize the positioning request of the network side, for example, the network positioning request which cannot be positioned is shielded, and the situation that the positioning session which is normally performed at present is influenced by the unavailable positioning request is prevented.
The network side in the present application may refer to a base station directly interacting with a terminal. After the terminal starts positioning, if a positioning request of the base station is received, it needs to be confirmed whether the positioning request contains available auxiliary positioning information.
In one embodiment, the preset availability condition further includes whether the location request is currently in a blacklist and whether a penalty timer corresponding to the location request is overtime.
Specifically, the present application may determine whether the location request is available according to the current list type of the location request and whether a penalty timer corresponding to the location request is expired. If the type of the current list of the positioning request is the blacklist, it can be determined that the positioning request is currently in the blacklist and belongs to positioning requests which cannot be positioned. If the penalty timer has not timed out, it is determined that the location request is currently within the penalty period, and the location request may be ignored. According to the method and the device, the network positioning request which causes the positioning failure is shielded through the blacklist, and the received unavailable positioning request is prevented from influencing the current normal positioning conversation through the punishment timer.
In one embodiment, the step of confirming that the positioning request satisfies the preset available condition may include:
if the positioning request is currently in the blacklist and the penalty timer corresponding to the positioning request is overtime, confirming that the positioning request meets the preset available condition under the condition that the positioning request contains available auxiliary positioning information;
and if the positioning request is not in the blacklist and the positioning request contains available auxiliary positioning information, determining that the positioning request meets a preset available condition.
Specifically, after the terminal starts positioning, if a positioning request issued by the network side is received at this time, it is determined whether the positioning request is in a blacklist, if the positioning request is in the blacklist, it is checked whether a punishment timer corresponding to the positioning request is overtime, if not, the positioning request is ignored, if the positioning request is overtime, it is determined whether auxiliary positioning information currently provided by the positioning request is available, and if the auxiliary positioning information is available, it is determined that the positioning request meets a preset available condition.
And if the positioning request is not in the blacklist currently, determining whether the auxiliary positioning information currently provided by the positioning request is available, and if so, determining that the positioning request meets a preset available condition. The punishment timer aims at the positioning request entering the blacklist, and the positioning request entering the blacklist is unavailable within the time length range of the timer.
In the method, the positioning request is managed by adopting the blacklist mode, and the type of positioning is not accepted before the timer is overtime, so that the situation that the terminal cannot report the position information due to interrupted continuous positioning is prevented. It should be noted that, the number of times that the positioning request is listed as the blacklist may be recorded, and further, the timing time of the punishment timer in the present application may be obtained according to the initial value of the timer and the number of times that the positioning request is added to the blacklist, so as to prevent the receiving of the unavailable positioning request from affecting the current and normally performed positioning session.
And 104, if the positioning request is confirmed to meet the preset available condition, performing satellite searching and positioning based on the available auxiliary positioning information.
Specifically, when the positioning request is confirmed to meet the preset available condition, the satellite original signal can be received based on the available auxiliary positioning information in the positioning request, and the satellite searching and positioning can be performed.
In the method, the management optimization is carried out on the positioning request of the network side, and the satellite searching and positioning can be carried out under the condition that the positioning request contains available auxiliary positioning information by confirming whether the positioning request meets the preset available condition. Specifically, the network positioning request which cannot be positioned can be shielded through the blacklist, and the influence of the unavailable positioning request on the current normally-performed positioning session is prevented through the penalty timer, so that the interference of the wrong positioning request on the network side to the terminal can be effectively avoided, the continuity of the terminal positioning service is improved, and the compatibility to the abnormal environment is better.
In one embodiment, as shown in fig. 2, a satellite positioning method is provided, which is described by taking the method as an example for a terminal, and includes the following steps:
step 202, receiving a positioning request issued by a network side under the condition of starting positioning, and then determining whether the positioning request meets a preset available condition. The preset available condition comprises that the positioning request comprises available auxiliary positioning information.
Specifically, the preset availability condition further includes whether the positioning request is currently in a blacklist, and whether a penalty timer corresponding to the positioning request is overtime.
And 204, if the positioning request is confirmed to meet the preset available condition, performing satellite searching and positioning based on the available auxiliary positioning information.
Specifically, when it is determined that the positioning request meets the preset available condition, the satellite original signal is received based on the available auxiliary positioning information in the positioning request, and the satellite searching and positioning are performed. It should be noted that, for step 202 and step 204, the specific implementation process thereof may refer to the description related to step 102 and step 104, and is not described again.
Step 206, the positioning request is removed from the blacklist, and the counting number of the positioning request added into the blacklist is cleared.
Specifically, if the positioning request is available, the satellite original signal can be received according to the auxiliary positioning information of the positioning request, and satellite searching and positioning are performed; meanwhile, if the positioning request is in the blacklist, the positioning request can be removed from the blacklist, and the counter of the punishment timer is cleared, so that the positioning request with the available auxiliary positioning information can be removed and managed in time.
And step 208, if the positioning request is confirmed not to meet the preset available condition, canceling positioning.
Specifically, if the positioning request does not satisfy the preset available condition, it may be determined that the positioning request is a positioning request that cannot provide available auxiliary positioning information, and the network positioning request process may be stopped.
In one embodiment, as shown in fig. 2, after the step 208 of canceling positioning, the method may further include the steps of:
step 210, adding the positioning request into a blacklist, starting a punishment timer corresponding to the positioning request, and updating the counting times of adding the positioning request into the blacklist; the timing time of the penalty timer is obtained according to the initial value of the timer and the counting times of the positioning request added into the blacklist.
Specifically, the positioning request is managed by adopting a blacklist mode, for the positioning request which can not provide available auxiliary positioning information, the positioning request is added into the blacklist, a punishment timer is started, the type of positioning is not accepted any more before the timer is overtime, and the situation that the terminal is interrupted in continuous positioning to cause that the position information can not be reported is prevented.
Moreover, the counting times of the positioning request added into the blacklist can be updated, and the timing time of the punishment timer is obtained according to the initial value of the timer and the counting times of the positioning request added into the blacklist; the method and the device adopt the blacklist to shield the network positioning request which causes the positioning failure, and adopt the timer to control the duration of the blacklist, so that the influence of frequently received unavailable positioning requests on the current normal positioning session is prevented.
To further elaborate on the scheme of the present application, fig. 3 is taken as an example, and the present application adopts a penalty timer T, the duration of which depends on a penalty timer initial value T0 and a counter c. The implementation process of the satellite positioning method can comprise the following steps:
step 301, after the terminal starts positioning, if a positioning request issued by the network side is received at this time, it is determined whether the terminal is in the blacklist, if the terminal is in the blacklist transferring step 302, if the terminal is not in the blacklist, the terminal is transferred to step 303.
Step 302, checking whether the penalty timer is overtime, if not, ignoring the positioning request, and if yes, turning to step 303;
step 303, confirming whether the currently provided auxiliary positioning information is available, if so, turning to step 304, and if not, turning to step 305;
step 304, receiving an original satellite signal according to the auxiliary positioning information, performing satellite searching and positioning, removing a blacklist, and resetting a counter c;
step 305, stopping the network positioning request process;
step 306, add the type of request to the blacklist and start a penalty timer T, the timing duration of which depends on the penalty timer initial value T0 and the counter c.
Specifically, for the penalty timer in the present application, the timing duration T is T0 × c. For example, T0 is 10s, if the location request is first added to the blacklist and the counter c is 1, then T is T0, and then if the location request is again received and still unavailable, then T is added to the blacklist and the counter c +1 (i.e. c is c +1) and T is T0.
According to the satellite positioning method, the blacklist is adopted to shield the network positioning request which causes the positioning failure; a timer is adopted to control the time length of the blacklist, and the influence of frequently received unavailable positioning requests on the current and normally-performed positioning conversation is prevented. The application provides a satellite positioning request management optimization scheme based on a blacklist and a penalty timer, which can effectively avoid the interference of a wrong positioning request at a network side to a terminal, improve the continuity of terminal positioning service, and is better compatible with abnormal environments.
It should be understood that although the various steps in the flow charts of fig. 1-3 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-3 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
In one embodiment, as shown in fig. 4, there is provided a satellite positioning apparatus including:
