DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with aspects related to the present disclosure as recited in the appended claims.

In related technologies, a high-speed-railway dedicated network is designed to ensure a smooth communication during high-speed moving. Both the high-speed-railway dedicated network and a public LTE network may cover a same area simultaneously, which involves cell handover between the high-speed-railway dedicated network and the public LTE network performed by user equipment (UE). But the handover of the UE from the high-speed-railway dedicated network to the public LTE network may have a low success rate when the UE is travelling at a high speed such as a speed of 200-300 km/h. If the handover fails, the communication of the UE may be interrupted, which prevents the user from communicating normally.

In embodiments of the disclosure, a base station configures a speed threshold for the UE. When a moving speed of the UE drops below the speed threshold, the UE performs cell measurement on adjacent cells in the public LTE network. When the measurement result meets a requirement for the handover, the UE may perform the handover from a cell in the high-speed-railway dedicated network to a cell in the public LTE network. In this case, the moving speed of the UE is lower and the success rate of the handover between the cells is higher, ensuring the smooth communication of the UE.

If the moving speed of the UE does not drop below the speed threshold, the UE does not perform the cell measurement on the adjacent cells in the public LTE network, which avoids the UE being handed over to the cell in the public LTE network. In this case, the UE mostly performs the handover between cells in the high-speed-railway dedicated network with a greater success rate.

FIG. 1 is a flowchart illustrating a network configuration method according to an exemplary embodiment of the disclosure. For example, the network configuration method is applied to a base station in a high-speed-railway dedicated network. As illustrated in FIG. 1, the method includes the following operations.

In operation 101, a random access request is received from UE.

In operation 102, a radio resource control connection reconfiguration signaling is sent to the UE, the radio resource control connection reconfiguration signaling carrying a preset first speed threshold. The first speed threshold is configured to instruct the UE to perform cell measurement on adjacent cells in a public LTE network when the UE moves at a speed less than the first speed threshold.

In the embodiment, a new message format of the radio resource control connection reconfiguration signaling is provided to add new information, i.e., the first speed threshold, into the radio resource control connection reconfiguration signaling. The first speed threshold is to instruct the UE to perform cell measurement on the adjacent cells in the public LTE network when the UE moves at a speed less than the first speed threshold. This makes the UE to be handed over to a cell in the public LTE network when the UE moves at a low speed, which increases a success rate of the handover. During a high-speed movement, the handover to a cell in the public LTE network is not performed as much as possible, while the handover to a cell in the high-speed-railway dedicated network is more often performed, which improves the success rate of the handover.

In an embodiment, the radio resource control connection reconfiguration signaling further carries a preset second speed threshold. The second speed threshold is configured to instruct the UE to perform no cell measurement on the adjacent cells in the public LTE network when the UE moves at a speed greater than the second speed threshold, the second speed threshold being not less than the first speed threshold.

In the embodiment, a new message format of the radio resource control connection reconfiguration signaling is provided to add new information, i.e., the second speed threshold, into the radio resource control connection reconfiguration signaling. The second speed threshold is to instruct the UE to perform no cell measurement on the adjacent cells in the public LTE network when the UE moves at a speed greater than the second speed threshold.

For example, the first speed threshold is about 60 km/h, and the second speed threshold is about 80 km/h. When the second speed threshold is greater than the first speed threshold, the UE may be prevented from frequently alternating between performing cell measurement on the adjacent cells in the public LTE network and performing no cell measurement on the adjacent cells in the public LTE network, so that power consumption of the UE may be reduced. When the moving speed of the UE changes from high to low, the first speed threshold is taken as a reference, and when the moving speed changes from low to high, the second speed threshold is taken as a reference. When the moving speed of the UE does not decrease to the first speed threshold, the second speed threshold is not taken as a reference for the moving speed, and cell measurement on the adjacent cells in the public LTE network is not required to be performed. After the moving speed of the UE decreases below the first speed threshold, the moving speed begins to rise, and cell measurement may be performed on the adjacent cells in the public LTE network before the moving speed rises to the second speed threshold.

In an embodiment, the radio resource control connection reconfiguration signaling further carries relevant information of an adjacent first cell in the public LTE network, which is used for instructing the UE to perform cell measurement on the first cell according to the relevant information when the UE moves at a speed less than the first speed threshold.

In the embodiment, a new message format of the radio resource control connection reconfiguration signaling is provided to add the relevant information of the adjacent first cell in the public LTE network into the radio resource control connection reconfiguration signaling. The relevant information of the first cell is to instruct the UE to perform cell measurement on the first cell according to the relevant information when the UE moves at a speed less than the first speed threshold. The first cell may include one or more cells. In the embodiment, one or more adjacent cells in the public LTE network, on which the UE is instructed to perform cell measurement, are referred to as the first cell.

The first cell may be a part of the adjacent cells in the public LTE network. In other words, the UE does not have to perform cell measurement on all the adjacent cells in the public LTE network, in order to reduce the power consumption of the UE. The first cell instructed by the radio resource control connection reconfiguration signaling may be adjacent cells on which handover is performed with a higher success rate. As a result, the success rate of the handover is increased.

The relevant information of the first cell includes information such as a cell identifier.

In an embodiment, the relevant information of the first cell is obtained in advance through one of the following manners.

In a first manner, relevant information of an adjacent first cell in the public LTE network is configured into a base station in the high-speed-railway dedicated network, when the base station in the high-speed-railway dedicated network or a base station in the public LTE network is established initially.

In the embodiment, the relevant information of the adjacent first cell in the public LTE network may be configured into the base station in the high-speed-railway dedicated network when the base station in the high-speed-railway dedicated network is established initially. A command may be sent through a control device to configure the relevant information of the adjacent first cell in the public LTE network, to the base station in the high-speed-railway dedicated network. Alternatively, when the base station in the public LTE network is established initially, the relevant information of the first cell, which is covered by the base station in the public LTE network, may be manually added into the base station in the high-speed-railway dedicated network.

In a second manner, relevant information of an adjacent first cell in the public LTE network is obtained via an X2 communication message when an X2 interface connection to an adjacent base station in the public LTE network is established initially.

In the embodiment, after the base station in the high-speed-railway dedicated network is established, the base station in the high-speed-railway dedicated network is initialized, which involves initial establishment of the X2 interface connection. The base station in the high-speed-railway dedicated network sends an X2 SET REQUEST (an X2 establishment request) to the adjacent base station in the public LTE network via an X2 interface (a communication interface between the base stations). The adjacent base station in the public LTE network feeds an X2 SET RESPONSE (an X2 establishment response), which carries the relevant information of the first cell covered by the local base station, back to the base station in the high-speed-railway dedicated network. Alternatively, after the base station in the public LTE network is established, the base station in the public LTE network is initialized, which involves the initial establishment of the X2 interface connection. The base station in the public LTE network sends the X2 SET REQUEST, which carries the relevant information of the first cell covered by the local base station, to the adjacent base station in the high-speed-railway dedicated network via the X2 interface.

In a third manner, relevant information of an adjacent first cell in the public LTE network is obtained by communicating with an adjacent base station in the public LTE network via an X2 communication message when a random access request is received from the UE for the first time.

In the embodiment, after the base station in the high-speed-railway dedicated network is established, when the base station receives the random access request from the UE for the first time, i.e., when configuration information of the relevant information of the adjacent first cell in the public LTE network is not found during search for local configuration information, the base station obtains the relevant information of the adjacent first cell in the public LTE network by sending the X2 communication message to the adjacent base station in the public LTE network via the X2 interface.

The above three manners may also be adopted in combination, for example, the relevant information of the first cell may be obtained at different times.

The UE can perform cell measurement on the adjacent cells periodically or according to an instruction of the base station in the high-speed-railway dedicated network. A measurement report is sent to the base station in the high-speed-railway dedicated network. The base station in the high-speed-railway dedicated network determines whether the UE needs to be handed over to the adjacent cell according to the received measurement report and initiates a handover process if it is determined that the handover is needed.

After receiving a handover request, the adjacent base station in the public LTE network judges whether the handover request is from the high-speed-railway dedicated network. If the handover request is from the high-speed-railway dedicated network, the adjacent base station in the public LTE network processes the handover for the UE in the high-speed-railway dedicated network first. For example, the adjacent base station in the public LTE network receives handover requests from at least two UEs in a very short period of time (such as about 100 milliseconds). If one of the at least two UEs is in the high-speed-railway dedicated network and another one is in the public LTE network, the handover request of the UE in the high-speed-railway dedicated network is processed firstly.

The network configuration method on the base station side is described above. A network measurement method on the UE side, which corresponds to the above network configuration method, is described below.

FIG. 2 is a flowchart illustrating a network measurement method according to an exemplary embodiment of the disclosure. The network measurement method is applied to a UE such as a cellphone or the like. As illustrated in FIG. 2, the method includes the following operations.

The UE is connected to a cell in the high-speed dedicated network.

In operation 201, a moving speed of the UE is monitored.

In operation 202, cell measurement is performed on adjacent cells in the public LTE network when the monitored moving speed is less than a preset first speed threshold.

In the embodiment, the UE may monitor its moving speed in real time or periodically. The manner in which the UE monitors its moving speed may be configured by a base station to which the UE belongs. When the UE moves at a speed less than the first speed threshold, cell measurement is performed on the adjacent cells in the public LTE network. When the UE moves at a speed not less than the first speed threshold, no cell measurement is performed on the adjacent cells in the public LTE network. In this case, power consumption of the UE during cell measurement is reduced. Further, the UE performs cell measurement on the adjacent cells in the public LTE network when the UE moves at a relatively low speed, and thus performs the cell handover at the relatively low speed, improving the success rate of the cell handover.

In an embodiment, no cell measurement is performed on the adjacent cells in the public LTE network when the monitored moving speed is greater than a preset second speed threshold. The second speed threshold is not less than the first speed threshold.

For example, the first speed threshold is about 60 km/h. The second speed threshold is about 80 km/h. When the second speed threshold is greater than the first speed threshold, the UE may be prevented from frequently alternating between performing cell measurement on the adjacent cells in the public LTE network and performing no cell measurement on the adjacent cells in the public LTE network, so that power consumption of the UE may be reduced. When the moving speed of the UE changes from high to low, the first speed threshold is taken as a reference, and when the moving speed changes from low to high, the second speed threshold is taken as a reference. When the moving speed of the UE does not decrease to the first speed threshold, the second speed threshold is not taken as a reference for the moving speed, and cell measurement on the adjacent cells in the public LTE network is not required to be performed. After the moving speed of the UE decreases below the first speed threshold, the moving speed begins to rise, and cell measurement may be performed on the adjacent cells in the public LTE network before the moving speed rises to the second speed threshold.

In an embodiment, the operation 202 includes performing cell measurement on an adjacent first cell in the public LTE network according to preconfigured relevant information of the first cell.

In the embodiment, the UE may only perform cell measurement on a part of the adjacent cells in the public LTE network rather than all the adjacent cells in the public LTE network according to configuration, which may reduce power consumption of the UE during the cell measurement. The configured adjacent first cell in the public LTE network may be an adjacent cell where the handover is performed with a higher success rate, such that the success rate of the handover can be increased.

In an embodiment, at least one of the first speed threshold, the second speed threshold or the relevant information of the adjacent first cell in the public LTE network is obtained through the following manner: sending a random access request to a base station in the high-speed dedicated network; and receiving a radio resource control connection reconfiguration signaling fed back by the base station in the high-speed dedicated network, the radio resource control connection reconfiguration signaling carrying at least one of the preset first speed threshold, the second speed threshold or the relevant information of the adjacent first cell in the public LTE network.

In the embodiment, a new format of the radio resource control connection reconfiguration signaling is provided to add the first speed threshold, the second speed threshold and the relevant information of the first cell into the radio resource control connection reconfiguration signaling. The UE may obtain the above information by parsing the radio resource control connection reconfiguration signaling in the new format.

The UE may further send a measurement report to the base station in the high-speed dedicated network. The base station in the high-speed dedicated network determines whether there is a need to perform the cell handover according to the received measurement report and initiates the handover process if the cell handover is needed.

The UE is connected to a cell in the high-speed dedicated network.

In operation 301, a moving speed of the UE is monitored.

In operation 302, it is determined whether the moving speed of the UE is less than a preconfigured first speed threshold; if the monitored moving speed is less than the preconfigured first speed threshold, operation 304 is performed, and if the monitored moving speed is not less than the preconfigured first speed threshold, operation 303 is performed.

In operation 303, cell measurement is performed on adjacent cells in the high-speed dedicated network.

In operation 305, the moving speed of the UE continues to be monitored to determine whether the moving speed is greater than a preconfigured second speed threshold. If the monitored moving speed is greater than the preconfigured second speed threshold, operation 306 is performed; and if the monitored moving speed is not greater than the preconfigured second speed threshold, operation 307 is performed.

FIG. 4 is a flowchart illustrating a method for random access and cell measurement according to an exemplary embodiment of the disclosure. The method for random access and cell measurement is applied to a base station and UE. As illustrated in FIG. 4, the method includes the following operations.

In operation 401, the UE sends a random access request to a base station in the high-speed dedicated network.

In operation 402, the base station in the high-speed dedicated network sends a radio resource control connection reconfiguration signaling to the UE, the radio resource control connection reconfiguration signaling carrying a preset first speed threshold.

In operation 403, the UE monitors its own moving speed.

In operation 404, when the monitored moving speed of the UE is less than the preset first speed threshold, the UE performs cell measurement on adjacent cells in the public LTE network. In addition, the UE may also perform cell measurement on adjacent cells in the high-speed dedicated network.

In operation 405, the UE sends a measurement report to the base station in the high-speed dedicated network.

In operation 406, the base station in the high-speed-railway dedicated network performs processing required for the cell handover according to the received measurement report.

The above embodiments can be combined freely according to an actual requirement.
