Embodiment 1

[0072] refer to figure 1 , which shows a flow chart of steps for an optimization method for inter-system handover measurement provided by an embodiment of the present invention. The optimization method for inter-system handover measurement can be applied to a base station, and may specifically include the following steps:

[0073] Step 101: When it is detected that the terminal establishes a voice bearer, and the event of starting intra-system inter-frequency measurement A2 reported by the terminal is received, add an inter-system cycle measurement event for the terminal.

[0074] In the embodiment of the present invention, the base station may be a macro base station, a micro base station, a radio remote base station, etc., which is not limited in the embodiment of the present invention.

[0075] The inter-system periodic measurement event refers to an event added by the base station for the terminal to periodically measure the signal strength of an inter-system.

Embodiment 2

[0117] refer to figure 2 , which shows a schematic structural diagram of a base station provided by an embodiment of the present invention, which may specifically include:

[0118] The different system cycle measurement event adding module 210 is used to add a different system cycle measurement event for the terminal when it detects that the terminal establishes a voice bearer and receives the start-up system inter-frequency measurement A2 event reported by the terminal; The cycle measurement result acquisition module 220 is used to obtain the latest different system cycle measurement result reported by the terminal from the current time when receiving the start-up different system voice A2 event reported by the terminal; the different system cycle measurement result judging module 230, for judging whether the different-system periodic measurement result meets the different-system signal strength condition required by the different-system handover; the different-system handov...

Abstract

The invention provides an optimization method and a base station for inter-system switching measurement. The method includes: when it is detected that the terminal establishes a voice bearer, and when the event of starting inter-system inter-frequency measurement A2 reported by the terminal is received, adding an inter-system cycle measurement event for the terminal; When starting the different-system voice measurement A2 event, obtain the latest different-system cycle measurement result reported by the terminal from the current time; judge whether the different-system cycle measurement result meets the different-system signal strength condition required by the different-system handover; In a case where the different-system cycle measurement result satisfies the different-system signal strength condition, a different-system handover command is sent to the terminal, and a different-system handover process is executed. The present invention can acquire the signal strength information of different systems in advance, can speed up the judgment of switching algorithm between different systems, thereby improving the success rate of voice switching between different systems, and further improving the perception of voice calls.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an optimization method and a base station for inter-system handover measurement. Background technique [0002] Interoperability between TD-LTE (TimeDivisionLongTermEvolution) network and heterogeneous network GERAN (GSMEDGE RadioAccessNetwork, GSM / EDGE Radio Access Network) or UTRAN (UMTS TerrestrialRadioAccessNetwork, UMTS Terrestrial Radio Access Network), including handover from 4G network To 2G or 3G network (voice interoperability is generally switching from 4G network to 2G network), currently triggering by configuration measurement, that is, on the basis of configuring the A2 event for the user to start the inter-frequency measurement in the system, and adding the inter-system start Measured A2 events. After starting the reporting of the A2 event of inter-system measurement, the base station configures B1 or B2 event measurement for inter-system handover for the us...
