Embodiment approach

[0085] As an implementation, the network reselection and network switching criteria are defined according to the speed dimension:

[0086] (1) Define mobile communication terminal user speed: V; speed offset (to avoid ping-pong switching): VHYS;

[0087] (2) When the user speed (V)<judgment speed V0, the speed dimension V switching algorithm is not started, and the existing network switching algorithm is used;

[0088] (3) Access conditions: the network signal strength RSRP is greater than the minimum access signal level threshold 8dB;

[0089] (4) When the user speed (V)>judgment speed V0, start the network speed dimension V switching algorithm;

[0090] (5) Frequency band occupation sequence: low frequency band (700~900MHz), middle frequency band (1700~2100MHz), high frequency band

[0091] (2500MHz~2690MHz), firstly determine whether the network has low-frequency, medium-frequency, high-frequency band networks, choose low-frequency band networks first, and then determine ...

Abstract

The invention relates to a network re-election and switching method, comprising the steps of requesting a mobile terminal to report speed information; receiving a measurement report returned by the mobile terminal, the measurement report containing the speed information of the mobile terminal; and determining whether to switch the network of the mobile terminal based on the speed information. The method of the invention solves the problem that an optimal network selection and switching solution cannot be offered for special scenarios such as high-speed movement and multi-network coverage areas and network interference complex regions, enhances the ability of a mobile communication network to make optimal network re-selection and switching for more different scenarios, and improves the network access index and the satisfaction of user perception.

Description

technical field [0001] The invention relates to a communication system and method, in particular to devices and methods for network reselection and network switching. Background technique [0002] Network reselection and network handover are one of the key technologies of mobile communication networks. During network reselection and network handover, existing mobile communication networks mainly judge mobile terminals based on signal strength RSRP (Reference Signal Received Strength) or signal quality RSRQ (Reference Signal Received Qualit). Reselect which base station cell to enter. However, this reselection and handover method relying on signal strength (RSRP) or signal quality (RSRQ) cannot provide the best solution for some scenarios such as: high-speed movement, multiple network coverage areas, complex network interference areas, etc. Perceived network reselection and switching solutions are prone to network dropouts, delays, etc., resulting in a decline in user percep...
