Description
Technical field
The present invention relates to field of mobile communication, relate in particular to the method and apparatus that the some standby numbers of a kind of double-module double-standby terminal switch between different mode networks.
Background technology
Along with the development of 3G (Third Generation) Moblie technology, TD-SCDMA, CDMA, third generation mobile technologies such as WCDMA have progressively entered the practical stage.But, the needs of supporting second generation mobile communication technology are arranged on third generation communication terminal owing to inevitably occur the problem of aspects such as the network coverage at the beginning of the networking of third generation mobile technology.Along with the development of technology such as WLAN (wireless local area network), the exigence terminal is supported the communication terminal of two or more patterns simultaneously simultaneously.Bimodulus and multimode terminal are produced by many equipment vendors recently, also are that some operators are selected.
At third generation mobile technology first stage of construction, common existence of 3G network and 2G network and 3G network cover under the perfect inadequately situation; The terminal of 3G network will be supported two kinds of network access techniques usually.Under different network environments, terminal is selected the network insertion of different mode.In order to realize that the network in the terminal standby process switches, the method that the network of definition terminal between different mode switches among the TS23.009 among the 3GPP (3G (Third Generation) Moblie partner plan).Based on the definition of the document, the dual-mode single-standby terminal is utilized the radio-frequency module of another pattern to carry out inter-frequency measurement between different access technologies, and measurement data is sent to access network system in the standby process of a certain pattern; Access net system judges whether to carry out to switch between the net of different mode networks, sends a message to terminal notice terminal and utilize between the radio-frequency module of the radio-frequency module of present mode and another pattern and net that network interaction is finished different mode networks and switch when needs switch.
But at double-module double-standby terminal, the radio-frequency module of every kind of pattern has one.Each radio-frequency module is all used by the baseband module of a pattern under the situation of two standbies, is implemented in the standby of heterogeneous networks.The network of realizing the inter-frequency measurement between the heterogeneous networks access technology and finishing between different mode networks switches the radio-frequency module that all can't use the another one pattern.So,, the situation of service disconnection will occur if when in the business under a certain mode network is carried out under the situation of two standbies, entering the network that do not have this pattern regional suddenly at present double-module double-standby terminal.This situation, can cause very big influence and use inconvenience the user such as voice call service at real time business.
If double-module double-standby terminal need realize according to the method stipulated among the 3GPP TS23.009, realize that network switching terminal between different mode must need each 2 of the radio-frequency modules of various patterns.Can cause the manufacturing cost of terminal too high so again.Simultaneously there is no need also to guarantee that terminal realizes all that under any circumstance two numbers all are in holding state, the most basic demand is to guarantee that aborted does not take place in business procedure standby numbers.
