Abstract

The invention discloses a shared carrier network border area network switching method and device. The method includes: when the user terminal is in the boundary area of ​​the shared carrier network and moves from the shared cell to the non-shared cell, acquiring frequencies of the shared cell and the non-shared cell; judging whether the frequency of the shared cell is the same as that of the non-shared cell ; If the frequency of the shared cell is different from that of the non-shared cell, a special inter-frequency reference signal reception quality RSRQ is used as a handover decision condition to perform network handover. The present invention sets a special handover strategy in the boundary area of ​​the shared carrier network, and adopts a novel RSRQ handover during inter-frequency handover, which can significantly improve the success rate of handover at the boundary; and avoids the obvious same-frequency interference of users on the side of the inter-frequency handover The phenomenon of repeated call drop occurs due to the signal, which improves the user experience.

Description

technical field [0001] The present invention relates to the field of LTE (Long Term Evolution, long-term evolution), in particular to a method and device for handover of a border area network of a shared carrier network. Background technique [0002] In the border area where the 4G network is shared (the border area between the shared network and the non-shared network), there must be two different situations between the two operators, one is the same frequency handover, and the other is the different frequency handover. Users on the inter-frequency handover side experience repeated call drops due to the presence of obvious inter-frequency interference signals, seriously affecting user experience. Contents of the invention [0003] In view of the above technical problems, the present invention provides a method and device for handover of a shared carrier network border area network, using a novel RSRQ (Reference Signal Receiving Quality) handover during inter-frequency han...
