Fig. 1 is a schematic diagram of interaction between a mobile base station and a core network device according to an embodiment, which includes the following steps.
S110, the core network equipment sends a paging request message to the mobile base station.
The core network device may be an electronic device integrated with a fourth generation mobile communication technology (4G) or a fifth generation mobile communication technology (5G), the mobile base station may establish a communication connection with the 4G or 5G core network device, for example, data transmission is performed through an S1 interface between the mobile base station and the core network device, and the S1 interface is a data communication interface between the mobile base station and the core network device.
The mobile base station refers to a radio transceiver station for information transmission with a mobile terminal in a certain radio coverage area through a mobile communication switching center, the mobile base station may be a backpack base station, the radio coverage area may be a satellite signal coverage area, the mobile communication switching center may be a satellite base station, and the mobile terminal may be an intelligent device (such as a smart phone, a personal computer, etc.) used by a user.
Before communicating with the core network device, the mobile base station needs to judge whether the mobile base station is in the satellite signal coverage period based on the satellite reference information.
The satellite reference information can be used to describe the coverage of the mobile base station by one or more signals of satellites, and the satellite reference information of the mobile base station can be determined by the core network equipment according to the position information of the mobile base station.
In some embodiments, the method of this embodiment may further include:
the mobile base station sends the position information of the mobile base station to the core network equipment; and receiving satellite reference information which is sent by the core network equipment and corresponds to the position information.
The satellite reference information may be determined by the core network device based on a satellite almanac, which is determined by the core network device based on location information of the mobile base station.
Data communication between the mobile base station and the core network device can be exemplarily shown in fig. 2A, the mobile base station is connected with the satellite through a wireless signal, and then connected with the network element of the core network device on the ground through the satellite, and for communication between the ordinary base station and the core network device for transmission, the communication is equivalent to a transmission section of "base station-core network device" that replaces the conventional wireless cellular network with a satellite link.
The position information of the mobile base station can be the longitude and latitude of the mobile base station under a global map, and the longitude and latitude of the mobile base station can effectively position the only position coordinate of the mobile base station on the earth.
It should be noted that the satellite ephemeris information may be ephemeris information of the target satellite.
The core network device may obtain the ephemeris information of the target satellite from the network management platform, where the ephemeris information of the target satellite may be ephemeris information of all satellites of a satellite network operated by an operator, or ephemeris information of part of satellites serving the mobile base station.
The ephemeris information of the target satellite is the ephemeris information of all satellites covered by the satellite signal to the mobile base station in a future period, wherein the ephemeris information can reflect the position and the speed of the corresponding satellite.
For example, the ephemeris information of the target satellite may correspond to the ephemeris information of each satellite corresponding to the position information covering the mobile station within a time period T1-T2, where T1 and T2 may be absolute time, such as time from 0 minutes and 0 seconds at 1/0 in 1980, or the ephemeris information of the target satellite may correspond to the ephemeris information of the satellite within a time period T3 in the future from now on, where T3 may represent a time period, such as 6 hours.
In addition, in this embodiment, the core network device may also provide only ephemeris information of the target satellite to the mobile base station, and the mobile base station may calculate the reference information of the target satellite based on the ephemeris information of the target satellite without providing the reference information of the target satellite.
The reference information and the ephemeris information are different in that: the ephemeris information needs to indicate which satellite covers the position of the mobile base station at each time, and the reference information only needs to indicate whether the position of the mobile base station at each time has satellite signal coverage, regardless of which satellite provides coverage.
For example, the target satellite includes: the ephemeris information of the target satellite can be covered by the satellite A within the time length of 0-T3, the satellite A covers within the time length of 0-T1, the satellite B covers within the time length of T1-T3, and the reference information of the target satellite is covered by the satellite signal within the time length of 0-T3.
Referring to fig. 2B as an example, before the time T1, the mobile station has satellite signal coverage, during the time period T1-T2, the mobile station has no satellite signal coverage, and from the time T2, the mobile station has satellite signal coverage again, since the moving track of the satellite is predictable, the coverage area and the coverage duration of the satellite are also predictable, and the reference information of the satellite can be inferred through the ephemeris information of the satellite, specifically, the geometric position of the satellite in a period of time can be inferred according to the ephemeris information of the satellite, and further, the coverage area of the satellite cell on the ground can be inferred, correspondingly, in fig. 2B, the reference information of the target satellite is before the time T1 and after the time T2.
As shown in fig. 2C, an operator operates two satellites, time corresponding to ephemeris information is represented by a straight line and a dashed line, a straight double-arrow line segment represents operation information of the satellite a, and the satellites a operate in T1-T2 and T3-T4'; the dashed double-arrow line segment represents the operational information of satellite B, which is operating after T1'-T2' and T4.
If the ephemeris information acquired by the core network device does not contain the information of the complete cycles of the satellite a and the satellite B, the ephemeris information of any satellite at any time cannot be inferred, and only the ephemeris information of the satellite in a period of the future can be inferred.
The target satellite may include at least two satellites, wherein the satellite reference information may include:
an original reference time period corresponding to position information of the mobile base station; and/or, a combined reference period obtained by de-duplicating an overlapping period in the original reference period, the combined reference period comprising at least one non-overlapping continuous period.
Wherein, the combined reference time interval can be obtained by the core network device in the following manner.
Removing the duplication of the overlapped time periods in the original reference time periods corresponding to the at least two satellites to obtain combined reference time periods corresponding to the at least two satellites, wherein the combined reference time periods comprise: at least one non-overlapping continuous period.
It should be noted that, when the satellite reference information only includes the original reference time period, the mobile base station may determine the combined reference time period based on the received original reference time period in the above manner.
Transmitting reference information of a target satellite to a mobile terminal, including: and transmitting the combined reference time periods corresponding to the at least two satellites to the mobile terminal.
In reference to the example shown in fig. 2C, the original reference time period corresponding to the location information of the target satellite covered mobile base station is: after T1-T2, T3-T4', T1' -T2', and T4, the overlapping time periods in the original reference time periods corresponding to at least two satellites are deduplicated, as exemplarily shown in fig. 2D, the obtained combined reference time periods corresponding to at least two satellites are: T1-T2' and T3, wherein at least one non-overlapping consecutive period comprises: T1-T2' and T3.
Therefore, the mobile base station sends the combined reference time periods corresponding to at least two satellites to the mobile terminal, so that the mobile terminal can visually know the satellite signal coverage condition of the position, and data communication is facilitated.
In addition, the core network device may cover an original reference time period corresponding to the location information of the mobile base station based on the target satellite signal, and perform deduplication on an overlapping time period in the original reference time period corresponding to at least two satellites to obtain a combined reference time period corresponding to at least two satellites, where the combined reference time period includes: and at least one non-overlapped continuous time interval, and then sending the combined reference time intervals corresponding to at least two satellites to the mobile base station, so that the mobile base station directly sends the combined reference time intervals corresponding to at least two satellites to the mobile terminal, thereby reducing the operation load of the mobile base station.
It should be noted that, when performing data transmission with the mobile base station, the core network device may send the original reference time period of the target satellite to the mobile base station, or send the combined reference time period of the target satellite to the mobile base station, or send the original ephemeris information of the target satellite to the mobile base station, or send the combined ephemeris information of the target satellite to the mobile base station.
The core network device may perform data communication with the mobile base station through broadcasting and the like, which is not limited in this disclosure.
In this disclosure, before the mobile base station sends the indication message to the core network device, the method may further include:
and acquiring a first preset time, and determining whether the paging response message can be sent to the core network equipment or not in the first preset time according to the satellite reference information of the mobile base station.
The first preset time corresponds to a time length between a receiving time of the paging request message and a satellite signal coverage ending time, and also corresponds to a time length between a sending time of the paging request message and the satellite signal coverage ending time, and the satellite signal coverage ending time can be a satellite signal ending time point determined by the mobile base station based on the satellite reference information.
In some embodiments, optionally, determining whether the paging response message can be sent to the core network device within the first preset time period according to the satellite reference information of the mobile base station includes:
comparing a second preset time length corresponding to the paging response message sent by the mobile terminal with the first preset time length; when the second preset time length is longer than the first preset time length, determining that the paging response message cannot be sent to the core network equipment within the first preset time length; and when the second preset time length is less than or equal to the first preset time length, determining that the paging response message can be sent to the core network equipment within the first preset time length.
The second preset time length is the time length required by the mobile terminal to send the paging response message to the core network device after the mobile terminal estimated by the mobile base station receives the paging message sent by the mobile base station.
Therefore, whether the paging response message can be sent to the core network equipment by the mobile base station in the satellite signal coverage period can be accurately judged by effectively predicting the time length required by the mobile terminal for sending the paging response message to the core network equipment.
The paging request message comprises a paging identifier of the mobile terminal, wherein the paging identifier is distributed to the mobile terminal by core network equipment; the implementation method can also comprise the following steps:
the mobile base station receives a paging request message sent by core network equipment, wherein the paging request message comprises a paging identifier of a mobile terminal, and the paging identifier is distributed to the mobile terminal by the core network equipment; sending a paging message to the mobile terminal according to the paging identifier; and determining that the mobile terminal is in the location area of the mobile base station based on the paging identification of the mobile terminal.
The core network equipment can send the paging identifier distributed for the mobile terminal to the mobile base station after determining that the mobile terminal establishes service connection with the core network equipment through the mobile base station.
The core network device may perform assignment of paging identifier based on the type/located area of the mobile terminal, where the paging identifier may be a number (e.g., 1), a letter (e.g., a), or a combination of a number and a letter (e.g., A1).
The mobile base station can be used as an information transmission carrier of the core network equipment and the mobile terminal based on the satellite signal, and the core network equipment sends the paging request message to the mobile base station, so that the mobile base station can send the paging message to the mobile terminal to obtain the paging response message sent by the mobile terminal.
And the mobile base station sends a paging message to the mobile terminal according to the paging identifier.
The location area (managed cell) of the mobile base station can cover a plurality of mobile terminals, each mobile terminal has a unique paging identifier to distinguish identity information thereof, it can be understood that information transmission between each mobile terminal and core network equipment included in the location area of the mobile base station can be completed by the mobile base station, and then the mobile base station can quickly find out the mobile terminal needing signal transmission based on the paging identifier of the mobile terminal.
It should be noted that, the mobile base station sends the paging message to the mobile terminal according to the paging identifier, and the mobile base station determines that the mobile terminal is located in the location area of the mobile base station based on the paging identifier.
The location area of the mobile base station is a management area of a device capable of communicating satellite signals with the mobile base station, such as a cell managed by the mobile base station.
And S120, when the mobile base station determines that the paging response message cannot be sent to the core network equipment within the first preset time period according to the satellite reference information of the mobile base station, the mobile base station sends an indication message to the core network equipment.
It should be noted that the mobile base station cannot send the paging response message to the core network device within the first preset time period, and when sending the indication message to the core network device, the mobile base station determines that there is satellite signal coverage at the current time based on the satellite reference information, and the satellite signal coverage ending time may be determined according to the satellite reference information.
Wherein the indication message can be used to indicate that the mobile base station cannot transmit the paging response message in the satellite signal coverage period.
The core network device may receive the indication message sent by the mobile base station within a third preset time period after the paging request message is sent to the mobile base station.
The core network device may assign a timer for paging transmission, and the timing duration of the timer may be a third preset duration, so that the paging transmission process is known in time by whether an indication message sent by the mobile base station is received within the third preset duration.
In this embodiment, after receiving the paging message sent by the mobile base station, the mobile terminal may send a paging response message to the mobile base station.
When receiving the paging message, the mobile terminal may generate a paging response message for feedback, and send the paging response message to the mobile base station, so that the mobile base station sends the paging response message to the core network device based on the satellite information.
The paging response message transmitted by the mobile terminal may be a NAS (Non-Access Stratum) message.
When the mobile base station receives the paging response message within a first preset time, determining whether the mobile base station is covered by satellite signals at the current moment based on the satellite reference information of the mobile base station; when the mobile base station is determined to be covered by satellite signals at the current moment based on the satellite reference information of the mobile base station, the paging response message is sent to the core network equipment, so that the real-time transmission of the message is facilitated.
And when the mobile base station determines that the mobile base station does not have satellite signal coverage at the current moment based on the satellite reference information, caching the paging response message until the mobile base station determines that the mobile base station has satellite signal coverage at the current moment, and sending the paging response message to the core network equipment.
The mobile base station can determine whether the sending time of the paging response message is covered by the satellite signal according to the satellite reference information, so that the time for sending the paging response message to the core network equipment can be determined.
As exemplarily shown in fig. 2E, when the mobile base station determines that there is no satellite signal coverage at the sending time of the paging response message, the mobile base station may buffer the received paging response message sent by the mobile terminal, and transmit the paging response message to the core network device when there is satellite signal coverage; when the mobile base station determines that the sending time of the paging response message is covered by the satellite signal, the mobile base station can directly transmit the paging response message to the core network device based on the satellite signal.
The satellite reference information of the mobile base station can reflect the coverage condition of the satellite signal in the area managed by the mobile base station, such as the satellite signal coverage time period, the satellite signal coverage range and the like.
In addition, a time stamp of the paging message sent by the mobile base station can be added to the paging response message sent by the mobile base station to the core network device, so that the core network device can know the transmission condition of the paging response.
After the core network device receives the indication message sent by the mobile base station, and when the paging response message sent by the mobile base station is not received within a third preset time period, the core network device indicates that the core network device has learned the reason that the mobile base station fails to send the paging response message in time, and can not perform unreachable marking on the service state between the mobile terminal and the core network device, so as to avoid the problem of false marking.
In addition, the core network equipment marks the service state between the mobile terminal and the core network equipment according to the time length between the receiving time point of the paging response message and the sending time point of the paging request message.
In some embodiments, the core network device receives a paging response message sent by the mobile base station, and when a time length between a receiving time point of the paging response message and a sending time point of the paging request message is less than or equal to a third preset time length, a service state between the mobile terminal and the core network device may be directly set as service reachable.
In other embodiments, the core network device receives a paging response message sent by the mobile base station, and modifies or sets a service state between the mobile terminal and the core network device to be service reachable when a time length between a receiving time point of the paging response message and a sending time point of the paging request message is greater than a third preset time length.
When the core network device does not receive the paging response message within the third preset time, the core network device can set the service state between the core network device and the mobile terminal as service unreachable until the core network device receives the paging response message outside the third preset time, and the service state between the core network device and the mobile terminal is changed from service unreachable to service reachable.
When the core network device does not receive the paging response message within the third preset time length, the core network device does not set the service state with the mobile terminal, and when the core network device receives the paging response message outside the third preset time length, the core network device sets the service state with the mobile terminal from the service unreachable state to the service reachable state.
The method comprises the steps that when the time length between the receiving time point of the paging response message sent by the mobile base station and the sending time point of the paging request message is longer than a third preset time length, the core network device indicates that a timer of the core network device reaches the expiration time, but if the indication message sent by the mobile base station is received before the expiration time of the timer, the fact that the paging response message which is not received by the mobile terminal on time is caused by the fact that the mobile base station does not have satellite signal coverage can be determined, service can be considered to be accessible with the mobile terminal, and paging transmission judgment is prevented from being influenced by the satellite signal coverage problem.
In some embodiments, optionally, after sending the paging response message to the mobile base station, the mobile terminal may set the operation state of the mobile terminal to a first state or a second state, where the first state is used to describe that there is no service connection between the mobile terminal and the mobile base station, and the second state is used to transmit data to the mobile base station through the paging identifier when the mobile terminal needs data transmission.
The mobile terminal is disconnected with the mobile base station in the first state, and needs to be reconnected with the mobile base station when data transmission is needed, and the mobile terminal is in the disconnected state in the second state, and can communicate with the mobile base station based on the paging identifier distributed to the mobile terminal by the core network equipment when data connection is needed, reconnection is not needed, and real-time communication efficiency is guaranteed.
In this embodiment, a mobile base station receives a paging request message sent by a core network device; when determining that the paging response message cannot be sent to the core network equipment within a first preset time period according to the satellite reference information of the mobile base station, sending an indication message to the core network equipment; the first preset time corresponds to the time length between the receiving time of the paging request message and the satellite signal coverage ending time, the satellite signal coverage ending time is determined according to the satellite reference information, and the indication message is used for indicating that the mobile base station cannot send the paging response message in the satellite signal coverage time period, so that the mobile base station timely informs the core network equipment when determining that the paging response message cannot be sent, and the problem that the core network equipment cannot receive the response message of the mobile terminal in the preset time period and can carry out reaching misjudgment on the mobile terminal is avoided.
