Embodiment Construction

[0046] The core idea of ​​the method of the present invention is: in the GPRS network, different threshold values ​​for switching to WCDMA are set for UEs in READY mode and UEs in STANDBY mode respectively. When the UE switches from the WCDMA network to the GPRS network, the UE judges whether it is currently in the READY mode. If it is, it controls the switching from the GPRS network to the WCDMA network according to the set switching threshold of the READY mode; otherwise, according to the set STANDBY mode The handover threshold value controls the handover from GPRS network to WCDMA.

[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] Please refer to figure 1 , figure 1 It is a flow chart of the mobile communication network switching control method provided by the present inven...

Abstract

The method is in use for setting up switching threshold from first network to second network for user equipment (UE) under connection mode, and setting up switching threshold from first network to second network for UE under idle mode. The method includes steps: (1) UE determines whether current mode is in connection mode; if yes, then executing step (2), otherwise executing step (3); (2) UE determines whether signal quality of second network satisfies switching threshold from first network to second network under connection mode; if yes, executing (4), otherwise, executing (1); (3) UE determines whether signal quality of second network satisfies switching threshold from first network to second network under idle mode; if yes, executing (4), otherwise, executing (1); (4) UE starts switching from first network to second network. The invention prevents ping-pong switching between networks, and guarantees UE resides second network in precedence.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a control method for switching of mobile communication networks. Background technique [0002] The current Global System for Mobile communication / General Packet Radio Service (GSM / GPRS) network is a relatively mature network, and its coverage is wider than that of the Wideband Code Division Multiple Access (WCDMA) network in the initial stage of construction. Division Multiple Access, WCDMA) network coverage is much wider. If the user equipment (User Equipment, UE) is in an area that cannot be covered by WCDMA, that is, it is in the WCDMA signal strength, such as received signal strength (Received Signal Code Power, RSCP) or signal-to-noise ratio (Ratio of energy per modulating bit to the total power spectral density, Ec / Io), the area below a certain threshold allows the UE to temporarily switch to the GSM / GPRS network. However, from the perspective of operation, it is hoped t...
