Description

Method, base station and terminal for realizing position confirmation

Technical Field

Background

Today, the location information is important data for event verification or security protection, and warning affairs (such as traffic accident, influenza virus, etc.) related to public security can be efficiently processed by verifying persons present in a specified area for a specified period of time.

The existing processing method mainly utilizes the time information and the position information of the occurrence of the alarm affair, and utilizes the obtained monitoring data to be called or the communication resources of the television broadcast, the network and the mobile operator to transmit the message, so that the related personnel can independently feed back the related position information and the time information according to the content of the message transmission. And the related department sorts the fed back position information and the time information to realize the processing of the alarm affairs. Although the processing of the alarm affairs can be improved to a certain extent by the message transmission mode, the message transmission and feedback are carried out by a large amount of manpower and financial resources, and accurate and complete time information and position information cannot be obtained; for example, in the case of a traffic offence, when no monitoring material is available, if the witness fails to view the content of the message in time, the handling of the case will be very difficult. For example, in a flu event, in order to take preventive measures for persons in contact with the pathogen, the persons at the same time and in the same area as the pathogen need to be fed back with time and position information in time, and the persons cannot necessarily receive the transmitted message in time or remember to stay at the position at all, which affects the control of the whole flu event.

In summary, for the processing of the alarm event, the existing method is adopted, so that a large resource cost is required for the message transmission and feedback of the alarm time, the efficiency of obtaining the time information and the position information of the personnel related to the alarm event is low, and the requirement of timely and efficient processing of the alarm event cannot be met.

Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The position information plays a great role in the big data era, is relatively sensitive, relates to personal privacy and needs to be prevented from being abused. When an alarm event occurs, the position information associated with the alarm event is acquired in time, which is important information for processing the alarm event.

In a wireless cellular communication system, a base station (eNB or base station) is a device that provides wireless access to User Equipment (UE), and the base station and the UE perform wireless communication through electromagnetic waves. A base station may include one or more cells through which a wireless communication system may achieve communication coverage for terminals within the coverage area.

In order to be able to provide wireless communication for users over a wide range, a wireless communication system needs to deploy base stations with large coverage, which are generally called macro base stations (macro enbs, macro bss), and serving cells of which are generally called macro cells (macro cells). In addition, according to the communication requirements and the usage environment of the user, it is necessary to provide a coverage hole for the user or provide a higher-quality wireless communication service, so that some small base stations (or transmission nodes, abbreviated as TPs) with a small coverage area and a low transmission power are adopted. These include micro base stations (PicoeNB or PicoBS) which may also be referred to as home base stations (HNB or HeNB), femto base stations or femto base stations, and sub base stations (FemtoBS or FemtoBS) which provide cells referred to as micro cells (picocells) and femto cells (femtocells). Nodes corresponding to the small base stations are also called Low Power Nodes (LPN), and cells corresponding to the nodes are also called small cells (smallcell).

In addition to wireless cellular communication systems, wireless communication systems also include wireless local access networks (WLANs, or WIFI). Because the WIFI spectrum is free and the cost of the WIFI chip is low, deployment and application of a wireless local area network access point (AP for short, also called as an access node) can provide a cheap way for wireless access and load distribution for operators and users.

The location information based on the base station cell identity is location information which is easy to obtain and low in cost. However, the location information in the wireless communication system is not used for the processing of the alarm event, the location information resource is not reasonably utilized, and the resource is not reasonably developed and applied for the alarm event.

Example 1

An alarm event (an infectious source contact event such as a criminal case, a vehicle accident case, influenza and the like, or a radiation source leakage/contact event) occurs at a place S in a certain city on X day and Y day, Mr. P is one of direct or indirect contacts at that time, and Mr. Q is a key person of the alarm event (for different alarm events, a suspect, an accident, an influenza pathogen carrier and the like can be selected).

Both mr. P and mr. Q handsets (where the handset is used as user equipment) store the resident location information and time information, where the location information is stored through the cell identifier (the user equipment may be in a connected state, or an idle state, or even in an airplane mode, or a power-off state). Since mr. P and mr. Q both have a stay in place S when the alarm event occurs, there should be a record of time information and position information corresponding to the stay in S in both the saved position information and time information.

In order to investigate an alarm event, information of key persons and contact persons related to the alarm event needs to be obtained, and investigators release the information of the alarm event in traditional ways such as a television station and a network; meanwhile, in order to speed up the processing process of the alarm event, the investigator broadcasts and sends a paging message or a system message (the radio access network may be a GSM network, a WCDMA network, a CDMA network, a TD-SCDMA network, an LTE network, a WIMAX network, a next generation radio access network, etc.) within a certain geographic range (for example, within a city range) through the radio access network of the operator, the paging message or the system message includes time (X day, Y time, Z minute) information and location information of the alarm event, and the location information may be a cell identifier (a global cell identifier CGI) adjacent to the location S; for example, the china mobile sends a paging message or a system message through the LTE network, where the location information included in the paging message or the system message is all cell or base station identifiers (such as an identifier of a GSM cell or base station, an identifier of a TD-SCDMA cell or base station, and an identifier of a TD-LTE cell or base station) of all system and all frequency bands adjacent to the place S of the alarm event; of course, the identity of the cell C where the alarm event occurrence address S is located is also included therein. The location information may also include WLAN service set identification SSID, basic service set identification BSSID of WLAN ap, latitude and longitude information of the location, and altitude information. To facilitate the initiation of paging or system message broadcasts over a large geographic area (e.g., within a city), the service server and core network server may participate in the transmission of paging or system messages over the wired network; specifically, the investigator may send the relevant time information and location information, and the geographical range information (e.g., tracking area identifier) of the broadcast message to the service server, where the service server sends the time information and location information to the base stations in the range through the core network server, and the base stations broadcast the paging message or system information to the user equipment through the air interface.

User equipment in the broadcast message sending geographic range receives the broadcast paging message or the system message; mr. P and mr. Q mobile phones are no exception. When the mobile phones of mr. P and mr. Q receive such paging message or system message respectively (mr. P and mr. Q may receive such paging message or system message at different locations, and the received location is not at the original location S), the mobile phones of mr. P and mr. Q compare the time information and the location information (including the identifier of the cell C where they have resided) in the broadcasted paging message or system message with the stored location information (e.g., cell identifier) and time information that have resided, and after matching succeeds, their mobile phones (in the case where mr. P and mr. Q are not known) send confirmation information to the network side, including the location information (cell identifier) and time information that are matched. Meanwhile, the acknowledgement information sent to the network side includes the current UE clock of the mobile phone, and the network side performs calibration on the time information in the acknowledgement information sent by the mobile phone according to comparison between the current clock of the mobile phone and the system clock (i.e., determines the time when mr. P and mr. Q appear in the cell C). The mobile phone receives the broadcasted paging message or the system message when in an idle state, the mobile phone accesses the network to send confirmation information to the network side by initiating a random access process, and the process of accessing the network is carried out by using an existing access cause value (such as a terminal-initiated signaling (MO-signaling)) or a cause value for establishing connection based on broadcasting. Except that the default idle-state mobile phone initiates a random access process to send the confirmation information to the network side, the idle-state mobile phone may also wait for the network access that needs to be triggered by the conventional service or signaling (the conventional service or signaling refers to the existing communication service or signaling, for example, a short message service, an internet access service, etc.) to send the confirmation information to the network side. In addition, the network side can indicate whether the user equipment is in an idle state in the transmitted broadcast, and immediately transmit the confirmation information through the access network after the matching is completed; or, in order to perform network overhead, the user equipment is instructed to perform network access of the traditional service or signaling within a preset time length, and the confirmation information is sent according to the network access triggered by the traditional service or signaling; when the preset time length (the maximum time delay allowed by the confirmation information) is reached and the traditional service or signaling is not carried out, the user equipment is directly accessed to the network to send the confirmation information.

When receiving the confirmation information sent by the mobile phones of Mr. P and Mr. Q, the network side obtains the mobile phone numbers (or mobile phone card numbers) of Mr. P and Mr. Q from the sent confirmation information, and investigators obtain the identity information of Mr. P and Mr. Q through the user subscription information and determine that the identity information appears near the incident place when the alarm event occurs from the confirmation information of the identity information; in order to make the investigation more smooth, the investigator asks the operators whether the operators know about the alarm event or not by pushing a short message to the operators and asks the operators to cooperate with the investigation. Through the processing, the situation that Mr. P does not see information released by a television station and a network is avoided, and investigators can further consult Mr. P according to the confirmation information. Through the confirmation information of Mr. Q, the investigator can also investigate whether Mr. Q is associated with the alarm event according to the confirmation information, thereby providing a direction for realizing the alarm event investigation. Further, in order to know the subsequent whereabouts of the relevant persons, the network side may instruct the mobile phone to send the location information to the network side after a subsequent location update (e.g., a change in the camping cell) occurs in the broadcast message or after receiving the confirmation information sent by the mobile phone.

In the method of the embodiment of the invention, the position information and the time information which are once resided by the mobile phone are stored in the storage space which is not influenced by mobile phone cards such as SIM or USIM, so that even if the key person of the alarm event changes the mobile phone card, the resident position information stored in the mobile phone can send confirmation information to the network side when the network side sends the broadcast message. Meanwhile, in order to avoid initiating access and reporting by a large number of internet of things terminals near the incident site, the internet of things terminals may not monitor such paging messages, or the network side may carry information (for example, access control AC level) indicating the terminal type or SIM/USIM card type when broadcasting the paging messages, and the terminal further takes whether to match its own terminal type as one of necessary conditions for reporting to the network side. In addition, the network side can also instruct the terminal to close the position recording function when necessary and/or listen to the paging message or the system information.

Example 2

The mobile phones (user equipment) of mr. P and mr. Q store the resident location information and time information, where the location information is stored through the cell identifier (the user equipment may be in a connected state, an idle state, or even in a flight mode, or a power-off state). Since mr. P and mr. Q both have a stay in place S when the alarm event occurs, there should be a record of time information and position information corresponding to the stay in S in both the saved position information and time information.

In order to find out the key persons and the contacters of the alarm event, investigators release information through a television station and a network; meanwhile, in order to speed up the processing process, the investigator broadcasts and sends a paging message within a certain geographical range (for example, within a city range) through the radio access network of the operator, wherein the paging message includes time (X day, Y time, Z minute) information of an alarm event and location information, and the location information may be cell identification (global cell identification CGI) adjacent to the place S. Of course, the identity of the cell C where the alarm event occurred is also in the identity. The location information may also include WLAN service set identification, SSID, basic service set identification, BSSID, of the WLAN ap, and latitude and longitude information for the location. And may also include longitude and latitude information and altitude information of the place. In order to facilitate the initiation of paging message broadcasts over a large geographic area (e.g., within a city), the service server and the core network server may participate in the transmission of paging messages over the wired network; specifically, the investigator may send the relevant time information and location information, and the geographical range information (e.g., tracking area identifier) of the broadcast message to the service server, where the service server sends the time information and location information to the base stations in the range through the core network server, and the base stations broadcast the paging message or system information to the user equipment through the air interface.

The user equipment in the paging geographic range receives the broadcasted paging message; certainly, when the mobile phones of mr. P and mr. Q receive such paging messages, the mobile phones of mr. P and mr. Q compare the time information and location information (including the identifier of the cell C in which they have resided) in the broadcasted paging message with the stored location information (e.g., cell identifier) and time information that have resided, and after matching succeeds, their mobile phones (in the case that mr. P and mr. Q are not aware of) send confirmation information to the network side, including the location information (cell identifier) and time information on the matching.

The network side also indicates in the broadcasted paging message: only transmitting the position information and the time information which are matched with the position information and the time information broadcasted by the network side and are resided by the mobile phone; or all the resident position information and time information stored by the mobile phone. Meanwhile, the acknowledgement information sent by Mr. P and Mr. Q to the network side includes the current UE clock of the mobile phone, and the network side performs calibration on the time information in the acknowledgement information sent by the mobile phone according to the comparison between the current clock of the mobile phone and the system clock (i.e. determining the time when Mr. P and Mr. Q appear in the cell C). The mobile phone receives the broadcasted paging message when in idle state, the mobile phone accesses the network to send confirmation information to the network side by initiating a random access process, and the process of accessing the network is carried out by using the existing access cause value (such as terminal-initiated signaling) or the cause value established based on the broadcast. Except that the default mobile phone in the idle state initiates a random access process to send the confirmation information to the network side, the idle mobile phone can also wait for the network access triggered by the traditional service or signaling to send the confirmation information to the network side. In addition, the network side can indicate whether the user equipment is in an idle state in the transmitted broadcast, and immediately transmit the confirmation information through the access network after the matching is completed; or, in order to perform network overhead, the user equipment is instructed to perform network access of the traditional service or signaling within a preset time length, and the confirmation information is sent according to the network access triggered by the traditional service or signaling; when the preset time length (the maximum time delay allowed by the confirmation information) is reached and the traditional service or signaling is not carried out, the user equipment is directly accessed to the network to send the confirmation information.

When receiving the confirmation information sent by the mobile phones of Mr. P and Mr. Q, the network side obtains the mobile phone numbers (or mobile phone card numbers) of Mr. P and Mr. Q from the sent confirmation information, and investigators obtain the identity information of Mr. P and Mr. Q through the user subscription information and determine that the identity information appears near the incident place when the alarm event occurs from the confirmation information of the identity information; in order to make the investigation more smooth, the investigator asks the operators to send a short message to the operators to find out whether the operators know about the alarm event, and asks the operators to cooperate with the investigation (the alarm event information can be pushed by a base station sending a broadcast message in the form of an air interface message, or can be pushed by other network side servers, such as a core network element or a service server, in the form of non-access stratum NAS information or service information). Through the processing, the situation that Mr. P does not see information released by a television station and a network is avoided, and investigators can further consult Mr. P according to the confirmation information. Through the confirmation information of Mr. Q, the investigator can also investigate whether the alarm event of Mr. Q is associated according to the confirmation information, thereby providing a direction for realizing the alarm event investigation.

Further, in order to know the subsequent whereabouts of the relevant persons, the network side may instruct the mobile phone to send the location information to the network side after a subsequent location update (e.g., a change in the camping cell) occurs in the broadcast message or after receiving the confirmation information sent by the mobile phone.

Example 3

An alarm event occurred at site S in a city from Z1 to Z2 on day X, where Mr. P is one of the contacts at that time, assuming an infection source contact event,

the mr. P mobile phone stores the resident location information and time information according to the setting, wherein the location information is stored through the cell identifier (the user equipment may be in a connected state, may be in an idle state, and may even be in a flight mode, or in a power-off state). Since mr. P has a stay in place S when the alarm event occurs, Z3 is divided to Z4 assuming X day Y; where, the sections Z3 to Z4 and Z1 to Z2 overlap each other, and there should be a record in the position information and the time information where P first survives.

In order to find potential contacts of the source of infection to the event, the health office publishes information via a television station and a network, and in order to speed up the process, the health office broadcasts a paging message (or system message) including time period (Z1 point X day Y, Z2 point X day Y, or Z1 point X day start time X day Y, time period length Z2-Z1 point) information of the alarm event and location information, which may be cell identification (global cell identification CGI) adjacent to the location S, within a certain geographical range (e.g., within a city-wide area) via the operator' S radio access network. Of course, the identity of the cell C where the alarm event occurred is also in the identity. The location information may also include WLAN service set identification SSID, basic service set identification BSSID of WLAN ap, latitude and longitude information of the location, and altitude information. To facilitate the initiation of paging or system message broadcasts over a large geographic area (e.g., within a city), the service server and core network server may participate in the transmission of paging or system messages over the wired network; specifically, the investigator may send the relevant time information and location information, and the geographical range information (e.g., tracking area identifier) of the broadcast message to the service server, where the service server sends the time information and location information to the base stations in the range through the core network server, and the base stations broadcast the paging message or system information to the user equipment through the air interface.

The user equipment in the paging geographic range receives the broadcasted paging message; when the mobile phone of mr. P receives such paging messages, the mobile phone compares the time information and the location information (including the identifier of the cell C where he has resided) in the broadcasted paging message with the location information (e.g. the cell identifier) and the time information (information of the time period) that have resided and are recorded in the mobile phone of mr. P, and after the matching is successful (the matching is successful, i.e. the location information is the same, e.g. the cell identifiers are the same, and the time periods are overlapped), the mobile phone of mr. P (in the case that mr. P is not aware) sends confirmation information to the network side, which includes the matched cell identifier and time information. When the mobile phone of mr. P is in an idle state, the mobile phone receives a broadcasted paging message, and by initiating a random access process, the mobile phone accesses into the network and sends a confirmation message to the network side, and the process of accessing into the network is performed by using an existing access cause value (e.g., a terminal-initiated signaling (MO-signaling)) or a cause value established based on the broadcast. Except that the default mobile phone in the idle state initiates a random access process to send the confirmation information to the network side, the idle mobile phone can also wait for the network access triggered by the traditional service or signaling to send the confirmation information to the network side. In addition, the network side can indicate the user equipment in the transmitted broadcast, and immediately transmit the confirmation information through the access network after the matching is completed when the user equipment is in an idle state; or, in order to perform network overhead, the user equipment is instructed to perform network access of the traditional service or signaling within a preset time length, and the confirmation information is sent according to the network access triggered by the traditional service or signaling; when the preset time length is reached and the traditional service or signaling is not carried out, the user equipment is directly accessed to the network to send the confirmation information.

When receiving confirmation information sent by the mobile phone of Mr. P, the network side obtains the mobile phone number (or the mobile phone number) of Mr. P from the sending confirmation information, investigators obtain the identity information of Mr. P through user subscription information, and confirms that the Mr. P appears near an incident place when an infection source contact event occurs from the confirmation information of the Mr. P; in order to make the investigation more smooth, the investigator sends a short message to the investigator by the operator to inquire whether the investigator knows about the infection source contact event and asks the operators to cooperate with the infection source contact event; for example, send a short message to Mr. P to ask if they are physically uncomfortable and ask them to cooperate. Through the processing, the situation that Mr. P does not see the information released by the television station and the network is avoided, and investigators can further consult Mr. P according to the confirmation information. Since Mr. P may not necessarily see the information sent by the health bureau through the television station or the network, Mr. P can be determined to be one of the possible persons on the scene under the condition that Mr. P is unknown by the method of the present invention so as to facilitate further notification, and the method also avoids occupying public resources such as the television station or the network. Further, in order to know the subsequent whereabouts of the relevant persons, the network side may configure the mobile phone to send the location information to the network side after the location update occurs in the broadcast message or after receiving the confirmation information sent by the mobile phone.

In order to avoid that a large number of terminals of the internet of things near the incident place send confirmation information when receiving network side broadcasts, and the network side indicates that the terminals can not monitor the network side broadcasts; or the network side carries information (such as access control AC level) capable of indicating the terminal type or SIM/USIM card type when broadcasting the position information and the time information, and the terminal further takes whether to match the terminal type of the terminal as a necessary condition whether to send the confirmation information to the network side. In addition, the network side can also close the position recording function and/or monitor the function of network side broadcast by indicating the terminal.
