Especially, when a user is in a vehicle such as a high-speed rail, the success rate of switching the network between the communication base stations of the mobile terminal is greatly influenced due to the high speed and the complex environment.

Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example one
In the moving process, the mobile terminal needs to continuously switch the communication base station to ensure smooth communication. The next communication base station to be accessed by the mobile terminal may be determined in advance on the condition that the moving range of the mobile terminal can be determined. The next communication base station to which the mobile terminal is about to access can start resource reservation for the mobile terminal in advance, and the relevant information of the reserved resource is forwarded to the mobile terminal through the communication base station to which the mobile terminal is currently accessed, so that the mobile terminal can be rapidly accessed to the next communication base station according to the relevant information of the reserved resource.
The technical solution of the present application will be described below by way of specific examples.
In the process of high-speed movement of the mobile terminal, when a user needs better network connection, a resource reservation request can be sent to a communication base station A to which the mobile terminal is currently accessed through the mobile terminal, so that the method for accessing the mobile terminal to the network is started.
The communication base station A responds to the resource reservation request of the mobile terminal, and sends the terminal related information of the mobile terminal collected by the communication base station A to the mobile terminal, namely the communication base station B to be accessed. The terminal related information comprises a base station number and a cell number of each communication base station in a plurality of communication base stations visited by the mobile terminal, and the network residence time of the mobile terminal of each communication base station.
When the communication base station B judges that the mobile terminal is accessed, the communication base station B receives and stores the terminal related information sent by the communication base station A, and judges whether the number of the communication base stations including the communication base station B accessed by the mobile terminal reaches a preset number threshold value. For example, the preset number threshold is 3, and the communication base station B may determine that the number of the communication base stations including itself accessed by the mobile terminal is 2. Therefore, the communication base station B needs to transmit the terminal-related information of the mobile terminal collected by itself to the communication base station C to which the mobile terminal is about to access, together with the terminal-related information stored and transmitted from the communication base station a.
And when the communication base station C judges that the mobile terminal is accessed, the communication base station C receives and stores the terminal related information sent by the communication base station B, and judges whether the number of the communication base stations including the communication base station C accessed by the mobile terminal reaches a preset number threshold value. The communication base station C can determine that the number of the communication base stations including itself accessed by the mobile terminal is 3, and the requirement of 3 of the preset number threshold is met. Therefore, the communication base station C sends the terminal-related information collected by itself to the server together with the terminal-related information stored from the communication base station B, so that the server can determine the moving route of the mobile terminal according to the terminal-related information.
Of course, the server may also acquire the terminal-related information of the mobile terminal collected by each of the communication base stations A, B and C, respectively.
Fig. 1 is a timing diagram illustrating a method for a mobile terminal to access a network according to an embodiment of the present application. As shown in fig. 1, a mobile terminal accesses a communication base station C. After receiving the terminal related information of the mobile terminal sent by the communication base station C, the server determines the moving route of the mobile terminal according to the terminal related information of the mobile terminal, and determines that the mobile terminal is the communication base station D to be accessed according to the moving route of the mobile terminal. And then the server sends the terminal related information and the moving stroke of the mobile terminal to the communication base station D and sends the moving stroke of the mobile terminal to the communication base station C, so that the communication base station D can reserve communication network resources for the mobile terminal in the corresponding expected network residence time, and when the communication base station D fails to reserve the communication network resources for the mobile terminal in the corresponding expected network residence time, the communication base station C can redetermine a next communication base station E which is newly about to be accessed by the mobile terminal according to the moving stroke of the mobile terminal and send the terminal related information and the moving stroke of the mobile terminal to the communication base station E. The moving journey comprises communication base stations which the mobile terminal needs to pass through and the expected network residence time within the service range of each communication base station.
After acquiring the terminal related information and the moving route of the mobile terminal, the communication base station D determines that the communication base station D is the communication base station to which the mobile terminal is to be accessed according to the moving route of the mobile terminal, and the communication base station C is the communication base station to which the mobile terminal is currently accessed.
And when the communication base station D judges that the communication base station is the communication base station to which the mobile terminal is to be accessed, allocating a target cell to which the mobile terminal is to be accessed, and reserving communication network resources for the mobile terminal in the corresponding predicted network residence time in the target cell.
Specifically, the communication base station D may allocate the target cell to the mobile terminal according to the load of each cell and the signal strength of the mobile terminal, or may allocate the target cell to each mobile terminal according to the priority of each mobile terminal.
And then, the communication base station D sends feedback information of success or failure of reserving communication network resources to the cell of the communication base station C which is currently accessed by the mobile terminal. When the communication network resources are reserved successfully for the mobile terminal in the corresponding expected network residence time, the communication base station D sends the area number of the target cell to the cell of the communication base station C to which the mobile terminal is currently accessed, so that the cell of the communication base station C can forward the area number of the target cell to the mobile terminal. When the communication network resource reservation for the mobile terminal at the corresponding expected network residence time fails, the information of the communication network resource reservation failure for the mobile terminal at the corresponding expected network residence time is sent to the cell of the communication base station C which is accessed by the mobile terminal at present, so that the cell of the communication base station C can determine the new next communication base station E to be accessed by the mobile terminal according to the moving stroke of the mobile terminal, and the terminal related information and the moving stroke of the mobile terminal are sent to the new next communication base station E to be accessed. Wherein the information that the communication network resource reservation is successful comprises the area code of the target cell.
When the communication base station C judges that the mobile terminal is accessed, it monitors the feedback information that the mobile terminal succeeds or fails to reserve the communication network resource for the mobile terminal, which is sent by the target cell of the communication base station D to which the mobile terminal is accessed: when the feedback information comprises the area code of the target cell, the area code of the target cell is forwarded to the mobile terminal, so that the mobile terminal can send a network access request to the target cell according to the area code of the target cell; and when the feedback information comprises the information of the failure of reserving the communication network resources, re-determining the new next communication base station E to be accessed by the mobile terminal according to the received movement stroke of the mobile terminal, and sending the terminal related information and the movement stroke of the mobile terminal to the new next communication base station E to be accessed by the mobile terminal.
And under the condition that the communication base station D successfully reserves the communication network resources for the mobile terminal in the corresponding expected network residence time, the communication base station D needs to be switched from C to D along with the continuous movement of the mobile terminal. Fig. 2 is a timing diagram illustrating a method for a mobile terminal to access a network after resource reservation is initiated according to an embodiment of the present application. As shown in fig. 2, the mobile terminal sends a network access request to the communication base station D. And the communication base station D receives the network access of the mobile terminal when receiving the network access request of the mobile terminal, and allocates the communication network resources reserved for the mobile terminal to the mobile terminal. So as to facilitate the mobile terminal to access the network quickly.
And if the target cell of the communication base station D does not receive the network access request of the mobile terminal within the expected network residence time, deleting the terminal related information and the moving stroke of the mobile terminal and canceling the communication network resource reserved for the mobile terminal so as to improve the utilization rate of the communication network resource.
After the mobile terminal accesses the communication base station D, the communication base station D continues to determine the next communication base station E to which the mobile terminal is to be accessed according to the mobile travel of the mobile terminal, and sends the terminal related information and the mobile travel of the mobile terminal to the next communication base station E to be accessed.
The communication base station E determines that the communication base station E is the communication base station to which the mobile terminal is about to access according to the moving range of the mobile terminal, and the communication base station D is the communication base station to which the mobile terminal is currently accessed.
And when the communication base station E judges that the communication base station is the communication base station to which the mobile terminal is to be accessed, allocating a target cell to which the mobile terminal is to be accessed, and reserving communication network resources for the mobile terminal in the corresponding predicted network residence time in the target cell.
And then, the communication base station E sends feedback information of success or failure of reserving communication network resources to the cell of the communication base station D which is currently accessed by the mobile terminal. When the communication network resources are reserved successfully for the mobile terminal in the corresponding expected network residence time, the communication base station E sends the area number of the target cell to the cell of the communication base station D which is accessed by the mobile terminal currently, so that the cell of the communication base station D can forward the area number of the target cell to the mobile terminal. When the communication network resource reservation for the mobile terminal fails in the corresponding expected network residence time, the communication base station E sends the information of the communication network resource reservation failure to the cell of the communication base station D which is accessed by the mobile terminal at present, so that the cell of the communication base station D can determine the new next communication base station F to be accessed by the mobile terminal according to the moving stroke of the mobile terminal, and sends the terminal related information and the moving stroke of the mobile terminal to the new next communication base station F to be accessed.
When the communication base station D judges the access of the mobile terminal, the communication base station D monitors the feedback information which is sent by the target cell of the communication base station E to which the mobile terminal is about to access and is used for successfully or unsuccessfully reserving the communication network resources for the mobile terminal: when the feedback information comprises the area code of the target cell, the area code of the target cell is forwarded to the mobile terminal, so that the mobile terminal can send a network access request to the target cell according to the area code of the target cell; and when the feedback information comprises the information of the failure of reserving the communication network resources, re-determining the new next communication base station F to be accessed by the mobile terminal according to the received movement stroke of the mobile terminal, and sending the terminal related information and the movement stroke of the mobile terminal to the new next communication base station F to be accessed by the mobile terminal.
Under the condition that the communication base station E successfully reserves the communication network resources for the mobile terminal in the corresponding expected network residence time, the communication base station D needs to be switched to the communication base station E along with the continuous movement of the mobile terminal. At this time, the mobile terminal sends a network access request to the communication base station E. Then, the mobile terminal and the communication base station repeat the interaction process as described above, which is not described herein again.
Under the condition that the communication base station D fails to reserve the communication network resources for the mobile terminal in the corresponding expected network residence time, the communication base station E reserves the communication network resources for the mobile terminal in the corresponding expected network residence time, and the interaction process with the mobile terminal and the communication base station F is repeated, which is not described herein again.
When the mobile terminal accesses the penultimate communication base station Y determined according to the moving stroke, the communication network resource reserved for the mobile terminal is allocated to the mobile terminal, and meanwhile, the communication base station Y sends the moving stroke of the mobile terminal to the mobile terminal, namely the last communication base station Z to be accessed. The communication base station Z may determine itself, that is, the last communication base station to be accessed by the mobile terminal in the moving process according to the moving process of the mobile terminal.
And when judging that the mobile terminal is accessed, the communication base station Z allocates the reserved communication network resources of the target cell to the mobile terminal. Meanwhile, the communication base station Z sends feedback information that the resource reservation task corresponding to the movement trip of the mobile terminal has been completed, to the mobile terminal and the server, respectively. The feedback information may include: the communication base station Z currently accessed by the mobile terminal is the last communication base station accessed by the mobile terminal determined according to the moving range of the mobile terminal, and the communication base station Z has completed the resource reservation task.
Further, the communication base station Z may delete the terminal related information and the movement trip of the mobile terminal and revoke the communication network resource reserved for the mobile terminal after sending the feedback information, or delete the terminal related information and the movement trip of the mobile terminal and revoke the communication network resource reserved for the mobile terminal after receiving the acknowledgement information of the feedback information of the mobile terminal and the server.
According to the technical scheme, in the process of high-speed movement of the mobile terminal, the movement stroke of the mobile terminal can be determined according to the historical stroke of the mobile terminal, so that the communication base station to be accessed by the mobile terminal can be predicted, communication network resources can be reserved for the mobile terminal by the mobile terminal in advance by the communication base station to be accessed by the mobile terminal, the mobile terminal can be accessed to the communication base station quickly, and the success rate of network residence is improved. The technical scheme of the invention reduces the signaling interaction between the mobile terminal and the communication base station, reduces the network switching time delay of the mobile terminal, allocates the reserved resources to the user for instant data transmission, improves the data transmission quality and improves the user experience.
Example two
Fig. 3 is a timing diagram illustrating a method for accessing a network by a mobile terminal according to another embodiment of the present application. As shown in fig. 3, referring to the first embodiment of the present invention, when a mobile terminal accesses a communication base station C, a server receives terminal related information of the mobile terminal from the communication base station C, determines a moving route of the mobile terminal according to the terminal related information of the mobile terminal, and then transmits the moving route of the mobile terminal to the communication base station C to which the mobile terminal is currently accessed.
After the communication base station C obtains the moving stroke of the mobile terminal, the communication base station C determines that the communication base station C is the communication base station which the mobile terminal is currently accessed to according to the moving stroke of the mobile terminal, and the communication base station D is the next communication base station which the mobile terminal is accessed to.
And the communication base station C sends the moving stroke of the mobile terminal, the terminal related information and the resource reservation instruction to the communication base station D, so that the communication base station D can respond to the resource reservation instruction to allocate a target cell to be accessed to the mobile terminal, and reserve communication network resources for the mobile terminal in the corresponding predicted network residence time in the target cell.
And the communication base station D acquires the terminal related information and the moving stroke of the mobile terminal sent by the communication base station C, and determines that the communication base station D is the communication base station to which the mobile terminal is to be accessed according to the moving stroke of the mobile terminal and the communication base station C is the communication base station to which the mobile terminal is currently accessed. When the communication base station D determines that the communication base station D is the next communication base station to which the mobile terminal is to be accessed, responding to a resource reservation instruction sent by the communication base station C to which the mobile terminal is currently accessed, allocating a target cell to which the mobile terminal is to be accessed, and reserving communication network resources for the mobile terminal in the corresponding predicted network residence time in the target cell.
Then, the communication base station D transmits feedback information of success or failure of resource reservation to the communication base station C. When the communication network resources are reserved successfully for the mobile terminal in the corresponding expected network residence time, the communication base station D sends the area number of the target cell to the cell of the communication base station C to which the mobile terminal is currently accessed, so that the cell of the communication base station C can forward the area number of the target cell to the mobile terminal. When the communication network resource reservation for the mobile terminal at the corresponding predicted network residence time fails, the information of the communication network resource reservation failure for the mobile terminal at the corresponding predicted network residence time is sent to the cell of the communication base station C which is currently accessed by the mobile terminal, so that the cell of the communication base station C can determine the new next communication base station E to be accessed by the mobile terminal according to the moving stroke of the mobile terminal, and the terminal related information, the moving stroke and the resource reservation instruction of the mobile terminal are sent to the new next communication base station E to be accessed. Wherein the information that the communication network resource reservation is successful comprises the area code of the target cell.
When the communication base station C judges that the mobile terminal is accessed, it monitors the feedback information that the mobile terminal succeeds or fails to reserve the communication network resource for the mobile terminal, which is sent by the target cell of the communication base station D to which the mobile terminal is accessed: when the feedback information comprises the area code of the target cell, the area code of the target cell is forwarded to the mobile terminal, so that the mobile terminal can send a network access request to the target cell according to the area code of the target cell; and when the feedback information comprises the information of the failure of reserving the communication network resources, re-determining the new next communication base station E to be accessed by the mobile terminal according to the received moving stroke of the mobile terminal, and sending the terminal related information, the moving stroke and the resource reservation instruction of the mobile terminal to the new next communication base station E to be accessed by the mobile terminal.
After the mobile terminal accesses the communication base station D, the communication base station D continues to determine the next communication base station E to which the mobile terminal is to be accessed according to the mobile stroke of the mobile terminal, and sends the terminal related information, the mobile stroke and the resource reservation instruction of the mobile terminal to the next communication base station E to which the mobile terminal is to be accessed.
