In roaming state, still reports and support LTE frequency range band 3,38,39,40,41, lead to the LTE that cannot access Hong Kong band 7
Network；Assume again that border only covers 7 network of Band of Hongkong, since terminal does not update band support, not to Band 7
It measures, therefore gravity treatment/redirection based on EPLMN can not be carried out.
For another example, as shown in Fig. 2, terminal is reported in Hongkong supports LTE frequency range band 3,7,8,40, it is assumed that border
It is covered with 40 network of Band of CONTINENTAL AREA OF CHINA, when roaming into CONTINENTAL AREA OF CHINA based on EPLMN, is not judged at oneself
In roaming state, still reports and support LTE frequency range band 3,7,8,40, lead to that China's Mainland band 38 and band39 cannot be accessed
LTE network；Assume again that border only covers 39 network of Band 38 or Band of CONTINENTAL AREA OF CHINA, since terminal does not update
Band support does not measure Band 38 and Band 39, therefore can not carry out gravity treatment/redirection based on EPLMN.
Based on the above issues, one aspect according to an embodiment of the present invention provides a kind of network search method, is being switched on

For example, it is assumed that China's Mainland network deploys TD-LTE band 38,39,40,41, on a small number of ground of China's Mainland
Area deploys LTE FDD band 3, and Hong-Kong network deploys LTE FDD 3,7,8 and TD-LTE of band band 40.
By taking China's Mainland is roamed into Hong Kong region as an example, it is big that China is resident in this booting network selection or before off-grid occurs
Land PLMN, and terminal does not receive the network configuration that Hong Kong network is made into EPLMN before this booting network selection or generation off-grid, and
Terminal does not search or was resident the LTE FDD cell under the PLMN at the PLMN of continent, then searches only for TD- after terminal off-grid
LTE (frequency range is Band 38,39,40,41), TD-SCDMA (3G) and GSM mode (2G) and corresponding band.For Hong-Kong
Region, mechanism is similarly.
2) if terminal is searching or had been resident third network in the case where first area searches or be resident the PLMN
Cell, the then cell of the all-network of first area described in terminal searching.Wherein, the cell of third network includes: first area

Terminal is during booting network selection or off-grid are searched again, if the public land for residing in first area before terminal moves
Dynamic net PLMN, and receive the configuration information that second area is configured to the EPLMN of first area, then terminal first searches for described first
The cell of the all-network in region searches again for the cell of the all-network of second area, and not repeat search.
For example, being resident China's Mainland PLMN in this booting network selection or before off-grid occurs, and this booting network selection or hair
Terminal has been received by the network configuration that Hong Kong network is made into EPLMN before raw off-grid, regardless of whether China's Mainland network is configured with
The adjacent area frequency point information of Hong Kong network and related observing and controlling information then need first to search for TD- after terminal booting network selection or generation off-grid
LTE, TD-SCDMA and GSM mode and corresponding band (LTE is Band 38,39,40,41), then search again for LTE FDD,
WCDMA mode and corresponding frequency range (LTE is Band 3,7,8), the network searched for before is not repeated to search for.For China
Hong Kong region, mechanism is similarly.
The network search method that this bright embodiment provides can be directed to the frequency range deployment scenario of country /region only to avoid terminal
The support standard and frequency range for opening the corresponding country /region lead to that neighbouring state cannot be accessed under the roaming scence based on EPLMN
The case where different systems and frequency range of family/regional network, occurs, and improves roaming success rate, and saves opening for radio-frequency devices
Pin, saves power consumption of terminal, improves roaming service customer's experience.
