The following further describes the content of the application by describing the embodiments with reference to the attached drawings.
The embodiment provides a paging method for a 5G network, which can be applied to a scenario where a user side stays in the same base station cell for a long time. For example, an application scenario of this embodiment may be an application scenario in which a user is in an office for a long time, in the application scenario, the user is generally in a seat at office time when the user is in the office for 8 hours, and at this time, the mobile phone of the user is also basically in the same position, and since the mobile phone position is unchanged, the mobile phone resides in a cell of a fixed base station for a long time, when the core network pages the mobile phone, the core network may page the mobile phone through the fixed base station, so as to load signaling of the 5G network. For another example, another application scenario of this embodiment may be an application scenario of the internet of things, where vehicles are parked in a garage at many times and the positions of the vehicles are unchanged, so that the vehicles usually reside in a cell of a fixed base station for a long time, and when the core network pages the vehicles, the core network may page the vehicles through the fixed base station, so as to provide a signaling load for the 5G network.
As shown in fig. 1 and fig. 2, the paging method of the 5G network provided in this embodiment may specifically include:
s10, when the core network pages the user end, the target base station corresponding to the user end is searched.
Specifically, the core network (AMF) is a core module of a 5G (5th generation mobile networks, fifth generation mobile communication technology) and is used for managing a user side accessing to the 5G network. A User Equipment (UE) is a 5G User Equipment for accessing a 5G network, where the User may be an electronic device with a function of accessing the 5G network, such as a smart phone, a tablet computer, and a smart watch.
The target base station includes base stations included in all tracking areas corresponding to the user side, that is, when the user side is paged, the target base station is in a pageable tracking area corresponding to the user side. The pageable tracking area corresponding to the user side can be a plurality of tracking areas, each tracking area in the plurality of tracking areas comprises a plurality of cells, and each cell in the plurality of cells corresponds to a candidate base station; and the tracking areas are different from the corresponding cells. It will be appreciated that each tracking area may correspond to a plurality of cells, but that each cell may only belong to one tracking area. For example, the ue corresponds to a tracking area a and a tracking area B, where the tracking area a includes a cell a and a cell B, and the tracking area B includes a cell c and a cell d, and then the cell a, the cell B, the cell c, and the cell d are different from each other. In addition, each cell corresponds to one candidate base station, and the candidate base stations corresponding to the cells are different from each other.
Certainly, in practical applications, the tracking area corresponding to the user end may change with the location change of the user end, however, when the user end is in idle, the core network acquires the tracking area corresponding to the user end, and when the user end is paged, the core network may perform paging in the tracking area corresponding to the user end, where the core network may store the tracking area corresponding to the user end in a tracking area list, and the tracking area list includes each tracking area corresponding to the user end in idle state, so that when the user end needs to be paged, the tracking area corresponding to the user end may be quickly determined.
The ue is connected to the 5G network and is in an idle state, that is, when the core network pages the ue, the ue is in the idle state. The target base station may be a base station to which the user terminal is connected last before being idle, or a base station with the highest priority in a tracking area corresponding to the user terminal, or a base station with the highest user frequency in the tracking area, or a base station reported by the user terminal.
In an implementation manner of this embodiment, the target base station is uploaded to the ue and stored in the core network. Therefore, when the core network pages the ue and before searching for the target base station corresponding to the ue, the method further includes:
and receiving and storing the target base station reported by the user side.
Specifically, when the user side reports the target base station, the user side in the idle state actively establishes a Non-Access-Stratum (NAS) connection with the core network, and sends the target base station to the core network through the Non-Access-Stratum connection. The non-access layer connection is actively established with the core network when the residence time of the user terminal in the cell corresponding to the target base station reaches a preset time threshold, wherein the preset time threshold may be preset, for example, 1 hour. It can be understood that, when the time length of the user terminal staying in a cell reaches a preset time threshold, the user terminal may actively send a request for establishing a non-access layer connection to the core network, the core network establishes a non-access layer connection with the user terminal based on the non-access layer connection request, the user terminal reports a target base station to the core network through the non-access layer connection, and the core network receives the target base station reported by the user terminal and stores the target base station, so that the core network can acquire the target base station corresponding to the user terminal when the core network needs to acquire the target base station corresponding to the user terminal. In addition, in practical applications, the ue may also establish a non-access point connection with the core network when the number of dwells in the cell reaches a preset number threshold (e.g., 10 times, etc.), and the ue is located in the cell before the ue is idle. .
In an implementation manner of this embodiment, the establishing process of the non-access stratum connection specifically includes:
when a user terminal stays in a cell, monitoring the stay time of the user terminal in the cell through the user terminal;
and when the stay time reaches a preset time threshold, actively establishing a non-access layer with the core network through a user terminal so as to conveniently report the target base station corresponding to the cell to the core network through the non-access layer connection.
Specifically, the starting time of the ue monitoring the staying time in the cell is the idle time of the ue, or the entering time of the ue entering the cell; when the starting time is that the user terminal is at an idle time, and when the stay time reaches a preset time threshold, taking the base station corresponding to the cell as a target base station; when the initial time is the entering time of entering the cell and the stay time reaches a preset time threshold, detecting the state of the user side through the user side, if the state of the user side is an idle state, taking the base station corresponding to the cell as a target base station, and if the state of the user side is not the idle state, continuously detecting the state of the user side; and when the self state is converted into the idle state and the user terminal continues to stay in the cell, taking the base station corresponding to the cell as the target base station.
In an implementation manner of this embodiment, when receiving a target base station, a core network detects whether the core network itself already stores a target base station corresponding to the user end, and if the target base station corresponding to the user end is stored, the target base station is used to replace the stored target base station, and if the target base station corresponding to the user end is not stored, the target base station is associated with the user end and then stored locally, so that when searching for the target base station corresponding to the user end, the target base station corresponding to the user end can be quickly determined, and the target base station is guaranteed to be the latest target base station, so that the possibility that the user end is paged by the target base station can be reduced to the greatest extent.
S20, when the target base station is found, paging the user terminal based on the target base station.
Specifically, the paging of the user terminal based on the target base station refers to sending paging information to the target base station, and when sending paging information to the target base station, no paging information is sent to other base stations in all tracking areas registered by the user terminal, so that the core network firstly sends a paging message to the target base station of the 5G cell where the user terminal stays, if the paging is successful under the target base station, no paging information is sent to other base stations in a plurality of tracking areas corresponding to the user terminal, if the paging is not successful under the target base station, then the paging is continuously performed on all candidate base stations included in a tracking area list allocated to the user terminal, so that the flow of the core network paging the user terminal in the 5G network can be optimized, and by trying to page the target base station where the user terminal stays for a long time, the operation of paging on all candidate base stations included in the tracking area list allocated to the user terminal is avoided as much as possible, therefore, unnecessary signaling flows of the core network paging user side can be reduced as much as possible, and the signaling load of the 5G network is reduced.
Based on this, in an implementation manner of this embodiment, the paging the ue based on the target base station specifically includes:
and sending the paging information corresponding to the user side to the target base station, and not sending the paging information to other base stations in a plurality of tracking areas corresponding to the user side so as to page the user side through the target base station.
Specifically, the other base stations are base stations other than the target base station in all base stations included in each tracking area registered by the user terminal, for example, the tracking area registered by the user terminal includes a tracking area a and a tracking area B, the tracking area a includes a base station a and a base station B, and the tracking area B includes a base station c and a base station d, where the base station a is the target base station, and then the other base stations include the base station B, the base station c, and the base station d. It can be understood that, after the target base station is determined, the operation of transmitting the paging information only to the target base station is performed first, and the operation of transmitting the paging information to all base stations included in each tracking area registered by the user terminal is not performed.
In an implementation manner of this embodiment, when the target base station is searched, there may be a case where the target base station is not found, and when the target base station is not found, it indicates that the ue stays in one base station cell for a long time, and at this time, the ue is directly paged in all tracking areas registered by the ue. It can be understood that the paging message is issued to all candidate base stations in all tracking areas registered by the ue to page the ue.
And S30, if the paging is not successful, paging the user terminal in a plurality of tracking areas corresponding to the user terminal.
Specifically, the unsuccessful paging indicates that the ue cannot be connected through the target base station, and the ue needs to be paged in a plurality of tracking areas corresponding to the ue, where the plurality of tracking areas are all tracking areas registered by the ue. It can be understood that, when the paging is not successful, the ue is paged in all tracking areas where the ue is registered, so that the success rate of paging the ue can be ensured, so that the core network can page the ue.
In an implementation manner of this embodiment, the paging the ue in the tracking areas corresponding to the ue specifically includes:
acquiring a plurality of tracking areas corresponding to the user side, and determining candidate base stations corresponding to the tracking areas;
and sending the paging information corresponding to the user side to each candidate base station so as to page the user side through each candidate base station.
Specifically, the tracking areas are all tracking areas registered by the user terminal, and the tracking area may include a plurality of cells, each cell corresponding to one candidate base station, so that each tracking area may correspond to a plurality of candidate base stations. After the candidate base stations corresponding to the tracking areas are obtained, the paging information corresponding to the user side can be directly issued to the candidate base stations, or after the candidate base stations corresponding to the tracking areas are obtained, the target base station is removed from the candidate base stations, and then the paging information is issued to the candidate base stations which want to be removed, so that the number of the paging information issued by the paging method provided by the implementation is the same as the number of the paging information issued by the existing paging method in the worst case.
In summary, this embodiment provides a paging method for a 5G network, where the paging method includes searching a target base station corresponding to a user side when a core network pages the user side; when the target base station is found, paging the user side based on the target base station; and if the paging is not successful, paging the user side in a plurality of tracking areas corresponding to the user side. When the user side is paged, the target base station corresponding to the user side is determined firstly, then the user side is paged through the target base station firstly, if the paging is successful, the user side paging is completed, and if the paging is not successful, the user side is paged in the plurality of tracking areas corresponding to the user side, so that when the user side stays in the cell where the target base station is located, the user side can be paged quickly, and all the tracking areas do not need to be paged, and the paging load can be reduced.
