technical field

The embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for cell handover or reselection in a heterogeneous network.

Background technique

The rapid development of the mobile Internet industry, on the one hand, as the driving force for the development of mobile network services, has accelerated the construction of mobile networks; Network construction and network operation pose challenges in many aspects. At the same time, the problem of uneven service distribution that already existed in the era of 2G and 3G networks is even more prominent. Due to the uneven distribution of population density, users of different age groups and different regions have greatly different needs for mobile services. Not only mobile services in different communities There are "cold" and "hot" service bearer requirements, and the service volume requirements of different geographical locations in the same community are also different.

Therefore, micro base stations began to rapidly enter the construction of mobile networks. In particular, it is more and more widely used to form a heterogeneous network architecture by making the micro base station and the macro base station different frequency networking, and the micro base station absorbs the traffic in the hot spot area of the macro base station, thereby forming a heterogeneous network architecture.

The method for inter-cell handover in the heterogeneous network in the prior art still follows the traditional cell handover method. That is, a scalar switching parameter is configured, and switching is performed when the scalar switching parameter reaches a switching threshold. Since the micro base station in the heterogeneous network is used to absorb heat for the macro base station, the macro network has established a basic network coverage guarantee as the underlying coverage network. If the traditional cell handover method is still used, it will not be able to fully meet the service experience needs of users. When the user performs high-priority services, the mobile terminal switches between the macro cell and the micro cell, resulting in an instantaneous degradation of the user's service experience during the switch.

Fig. 1 is a flow chart of Embodiment 1 of a method for cell switching or reselection in a heterogeneous network according to the present invention. As shown in Fig. 1 , the execution subject in this embodiment is a device for cell switching or reselection in a heterogeneous network. The device for cell handover or reselection in the heterogeneous network is integrated in the macro base station and the micro base station, so the reactive power optimization method for the wind farm provided in this embodiment includes the following steps.

Step 101, setting a parameter floating range for cell handover or reselection in a heterogeneous network.

Wherein, the handover parameter or the reselection parameter may respectively be: Reference Signal Received Power (English: Reference Signal Received Power, RSRP for short). Both the switching parameter and the reselection parameter are in a floating range, that is, on the basis of the scalar switching or reselection parameter x in the prior art, both the switching parameter and the reselection parameter are expanded into an interval range. For example, the switching parameter is [x-a,x+b]. Wherein, x is a scalar handover parameter, and the values of a>0, b>0a and b can be different, which can be set according to the trade-off strategy of user average moving speed, cell capacity and user experience.

Step 102, predicting the behavior track of the mobile terminal user.

Specifically, the device for cell switching or reselection in the heterogeneous network in the base station can predict the behavior track of the mobile terminal user according to the measurement information of the serving cell or neighboring cells fed back by the terminal.

Wherein, if the serving cell is a macro cell, the neighboring cell is a micro cell. Or the serving cell is a micro cell, and the neighboring cell is a macro cell. To meet the heterogeneous network architecture.

Step 103, judging whether the mobile terminal is about to perform cell handover or reselection in a heterogeneous network according to the behavior track of the mobile terminal user.

Specifically, in this embodiment, if the behavior track of the mobile terminal user is moving from the macro cell to the micro cell, and moves to a location where a heterogeneous network cell handover or reselection is about to take place, it is determined that the mobile terminal is about to perform heterogeneous network cell switching or reselection. Cell handover or reselection, otherwise there is no cell handover or reselection in the heterogeneous network.

Step 104, if it is determined that the mobile terminal is about to perform cell handover or reselection in a heterogeneous network, control the mobile terminal to perform cell handover or reselection according to the floating range of the handover parameter or the floating range of the reselection parameter and whether high-priority services are in progress.

Specifically, in this embodiment, if it is determined that the mobile terminal is about to perform cell handover or reselection in a heterogeneous network, the state of the mobile terminal is judged, and if the mobile terminal is in a connected state, it is judged whether the mobile terminal is performing a high-priority service, If the mobile terminal is performing high-priority services, cell handover will be performed after the mobile terminal stops high-priority services, or the user continues to perform high-priority services, but the current handover parameters have reached the left and right thresholds of the handover parameter floating range, then control The mobile terminal performs cell handover. In order to ensure that the mobile terminal does not perform cell switching when performing high-priority services as much as possible, and improve the user experience of users performing high-priority services as much as possible. If the mobile terminal is in an idle state, that is, no task service is performed, it is judged whether the reselection parameter of the mobile terminal falls within the floating range of the reselection parameter, and if it falls within the floating range of the reselection parameter, then the mobile terminal is controlled to perform cell reselection. In order to make the mobile terminal perform cell reselection in advance, it is avoided that the time when the mobile terminal transitions from the idle state to the connected state for high-priority services is the same as the time for cell handover, so that the user experience of high-priority services is reduced.

Wherein, the high-priority service refers to a service with a higher QCI level or extended QCI level. High-priority services can be set in advance, specifically according to market strategies and user business habits.

Wherein, the left and right thresholds of the floating range of the switching parameter refer to the leftmost and rightmost values within the switching parameter range. As in the above example, the left threshold and right threshold of the floating range of the switching parameter are: x-a, x+b respectively.

The method for cell handover or reselection in a heterogeneous network provided in this embodiment is to set the floating range of parameters for cell handover or reselection in a heterogeneous network; predict the behavior track of a mobile terminal user; judge according to the behavior track of a mobile terminal user Whether the mobile terminal is about to perform cell handover or reselection of the heterogeneous network; if it is determined that the mobile terminal is about to perform cell handover or reselection of the heterogeneous network, then control the mobile terminal according to the floating range of the handover parameter or the floating range of the reselection parameter and whether it is in progress High-priority services undergo cell switching or reselection. Since the handover or reselection parameters are set to a floating range, it is possible to control the mobile terminal to perform cell reselection or handover in advance or later than in the prior art, so as to minimize the number of users performing cell handover for high-priority services. The user experience of the user performing high-priority services is improved.

Figure 2 is a flow chart of Embodiment 2 of the method for cell switching or reselection in a heterogeneous network according to the present invention. As shown in Figure 2, the method for cell switching or reselection in a heterogeneous network provided by this embodiment is in the Method for cell switching or reselection in a heterogeneous network Based on the first embodiment, step 102 to step 104 are further refined, and the method for cell switching or reselection in a heterogeneous network provided in this embodiment includes the following steps.

Step 201, counting the current load situation, and judging whether both the uplink and downlink thresholds of the load are lower than the alarm threshold, if yes, execute step 202, otherwise, end.

Further, in this embodiment, the devices for cell switching or reselection in the heterogeneous network in the macro base station and the micro base station respectively count the current load situation, if the uplink and downlink load thresholds of the macro base station are both less than the alarm threshold, and the uplink of the micro base station and the downlink load threshold are less than the alarm threshold, it means that the load conditions of the macro base station and micro base station for cell switching or reselection meet the conditions for cell switching or reselection in this embodiment, and the macro base station and micro base station have the ability to perform this implementation The method for cell handover or reselection in the heterogeneous network provided in the example.

Among them, the alarm threshold can be set according to the operator's policy and the average load of the network. It represents the load capacity of the base station. When the load of the base station is higher than the alarm threshold, if the user's service demand further increases, the base station will not be able to guarantee the user's service experience.

Step 202, setting a floating range of parameters for cell handover or reselection in the heterogeneous network.

In this embodiment, the implementation manner of step 202 is the same as the implementation manner of step 101 in Embodiment 1 of the method for cell handover or reselection in a heterogeneous network of the present invention, and will not be repeated here.

Step 203, predicting the behavior track of the mobile terminal user according to the measurement information of the serving cell or neighboring cells fed back by the mobile terminal.

Further, if the serving cell is a macro cell and the neighboring cell is a micro cell, predict the behavior trajectory of the mobile terminal user according to the measurement information of the serving cell or neighboring cells fed back by the mobile terminal, specifically including: according to the measurement information of the neighboring cells fed back by the mobile terminal Measurement information, counting whether the signal strength in the measurement information of adjacent cells continues to increase. If the signal strength continues to increase, determine that the behavior track of the mobile terminal user is moving from a macro cell to a micro cell and arriving at a cell that is about to be handed over to a heterogeneous network Location.

If the serving cell is a micro cell and the adjacent cell is a macro cell, predict the behavior trajectory of the mobile terminal user according to the measurement information of the serving cell or adjacent cell fed back by the mobile terminal, specifically including: according to the measurement information of the serving cell fed back by the mobile terminal, Statistics on whether the signal strength in the measurement information of the serving cell continues to decrease. If the signal strength continues to decrease, determine that the mobile terminal user's behavior track is moving from the micro cell to the macro cell and arriving at the location where the cell handover of the heterogeneous network is about to take place .

Wherein, the method for judging whether the signal strength of the adjacent cell continues to increase may be: continuously counting the measurement information of the adjacent cell fed back by the mobile terminal for two consecutive times, if the signal strength of the adjacent cell is higher in the later one than in the earlier one, it accounts for 10% of the total number of times If the ratio exceeds the threshold, it is judged that the signal strength of the adjacent cell continues to increase. The threshold can be set according to actual network deployment and environmental factors, for example, it can be set to 80%. The method for judging whether the signal strength of the serving cell continues to decrease can be as follows: continuously count the measurement information of the serving cell fed back by the mobile terminal for two consecutive times, if the later one is compared to the earlier one, the ratio of the number of times the signal strength of the serving cell is low to the total number of times If the threshold is exceeded, it is judged that the signal strength of the serving cell continues to decrease. The threshold can be determined according to actual network deployment and environmental factors, for example, it is set to 80%.

In this embodiment, since the macro cell is far larger than the micro cell, when the serving cell is a macro cell and the neighboring cell is a micro cell, the method of counting whether the signal strength in the measurement information of the neighboring cells continues to increase is used to predict the behavior of mobile terminal users trajectory, and when the serving cell is a micro cell and the adjacent cell is a macro cell, the method of counting whether the signal strength in the measurement information of the serving cell continues to decrease predicts the behavior trajectory of the mobile terminal user, making the prediction result more accurate.

Step 204, judge whether the mobile terminal is about to perform cell handover or reselection in a heterogeneous network according to the behavior trajectory of the mobile terminal user, if yes, execute step 205, otherwise, end.

In this embodiment, if the behavior trajectory of the mobile terminal user is to move from the macro cell to the micro cell and arrive at the location where the cell handover of the heterogeneous network is about to take place, it is determined that the mobile terminal is about to switch or reselect from the macro cell to the micro cell, Or, if the behavior track of the mobile terminal user is moving from the micro cell to the macro cell and arrives at a location where the cell handover of the heterogeneous network is about to take place, it is determined that the mobile terminal is about to switch or reselect from the micro cell to the macro cell.

Step 205, judging whether the state of the mobile terminal is idle, if yes, execute step 206, otherwise, execute step 207.

In this embodiment, the state of the mobile terminal can be judged according to whether the mobile terminal is running a service. If the state of the mobile terminal is not performing services, the mobile terminal is in an idle state, otherwise the mobile terminal is in a connected state.

Step 206, sending the floating range of the reselection parameter to the mobile terminal, so as to control the mobile terminal to perform cell reselection after the mobile terminal determines that the reselection parameter falls within the floating range of the reselection parameter.

Further, in this embodiment, the floating range of the reselection parameter may be sent by sending a paging message to the mobile terminal, that is, the floating range of the reselection parameter may be carried in the paging message and sent to the mobile terminal. The mobile terminal judges whether the reselection parameter falls within the floating range of the reselection parameter, and if it is determined that the reselection parameter falls within the floating range of the reselection parameter, the device for cell handover or reselection in the heterogeneous network controls the mobile terminal to perform cell reselection.

Preferably, when the mobile terminal determines that the reselection parameter is equal to the left and right thresholds of the floating range of the reselection parameter, the mobile terminal can be controlled to perform cell reselection. Similarly, the left and right thresholds of the floating range of the reselection parameter are the leftmost value and the rightmost value of the floating range of the reselection parameter.

Step 207, sending the handover parameter floating range to the mobile terminal.

Further, in this embodiment, the handover parameter floating range may be sent to the mobile terminal through an RRC reconfiguration message, that is, the handover parameter floating range is carried in the RRC reconfiguration message.

Step 208, judge whether the mobile terminal is performing high-priority services, if yes, execute step 209, otherwise execute step 210.

Further, the ongoing service of the mobile terminal may be compared with the preset high-priority service, and if the ongoing service exists in the preset high-priority service, it is determined that the mobile terminal is performing the high-priority service.

Step 209, control the mobile terminal to perform cell handover after the mobile terminal stops performing high-priority services or when the handover parameter reaches the left and right thresholds of the handover parameter range.

Further, in this embodiment, it is judged whether the mobile terminal stops performing high-priority services, and at the same time, it is monitored whether the handover parameter of the mobile terminal is within the range of the handover parameter. If the mobile terminal stops performing high-priority services, cell handover is performed. Or the user continues to perform high-priority services, but the current handover parameter has reached the left and right thresholds of the handover parameter floating range, and the mobile terminal is still controlled to perform cell handover.

After step 209 is executed, end.

Step 210, controlling the mobile terminal to perform cell handover.

If the mobile terminal is not performing high-priority services but low-priority services, cell handover has little impact on the user experience of low-priority services, so as long as the handover parameters of the mobile terminal are within the floating range of the handover parameters, control the mobile terminal Perform cell handover.

The method for cell handover or reselection in a heterogeneous network provided in this embodiment, by counting the current load situation, if the uplink and downlink thresholds of the load are both smaller than the alarm threshold, set the parameter floating range for handover or reselection of the cell in the heterogeneous network According to the measurement information of the serving cell or neighboring cells fed back by the mobile terminal, predict the behavior trajectory of the mobile terminal user, and judge whether the mobile terminal is about to perform cell handover or reselection of the heterogeneous network according to the behavior trajectory of the mobile terminal user, and if so, judge Whether the state of the mobile terminal is idle state, if so, then send the reselection parameter floating range to the mobile terminal, so as to control the mobile terminal to perform cell reselection after the mobile terminal determines that the reselection parameter falls within the reselection parameter floating range. Otherwise, send the handover parameter floating range to the mobile terminal, and judge whether the mobile terminal is carrying out high-priority business, if so, then control the mobile terminal to carry out after the mobile terminal stops carrying out the high-priority business or when the handover parameter reaches the left and right thresholds of the handover parameter range. Cell switching. The service experience for users performing high-priority services is improved. And when predicting the behavior track of the mobile terminal user according to the measurement information of the serving cell or the neighboring cell fed back by the mobile terminal, if the serving cell is a macro cell and the neighboring cell is a micro cell, then according to the measurement information of the neighboring cell fed back by the mobile terminal, Count whether the signal strength in the measurement information of adjacent cells continues to increase. If the signal strength continues to increase, determine that the mobile terminal user's behavior trajectory is moving from the macro cell to the micro cell and arriving at the location where the cell handover of the heterogeneous network is about to take place. If the serving cell is a micro cell and the adjacent cell is a macro cell, according to the measurement information of the serving cell fed back by the mobile terminal, it is counted whether the signal strength in the measurement information of the serving cell continues to decrease. The behavior trajectory of the terminal user is to move from the micro cell to the macro cell and arrive at the location where the cell handover of the heterogeneous network is about to take place. It makes the prediction of the user's behavior trajectory more accurate, and makes a more accurate judgment on whether cell switching or reselection is about to be performed.
