Embodiment 1
[0075] An embodiment of the present application provides a method for searching a network, which is executed by a user equipment UE, the UE has a first modem module and a second modem module, and the first modem module and the second modem module Both modem modules support LTE. The method can be applied in scenarios where the UE is roaming (such as international roaming), or the UE is at the border of two countries or regions, or the UE is at the border of two PLMNs. The UE may be a mobile phone, a tablet computer (PAD), and other devices capable of performing network search.
[0076] Such as figure 1 As shown, the method includes:
[0077]S110: The first modem module searches a first frequency band range through a first radio frequency unit of the UE, so as to obtain first information, where the first information is used to determine a geographic location of the UE.
[0078] The first information may be a mobile country code MCC, and the range of the third frequency band d...
Embodiment 2
[0092] A schematic structural diagram of a UE provided in this application, such as figure 2 As shown, the UE 200 may include: a processor 202, a memory 201, a first modem module 2041, a second modem module 2042, a first radio frequency unit 205, and a second radio frequency unit 206;
[0093] The memory 201 is used to store instructions;
[0094] The processor 202 is configured to call the instruction in the memory 201, and control the first modulation and demodulation module 2041, the second modulation and demodulation module 2042, the first radio frequency unit 205 and the second radio frequency unit 205. The second radio frequency unit 206 executes any method provided in the embodiments of the present application. The above components can be connected through the bus 203 .
[0095] Such as figure 2 As shown in , the UE 200 may further include a first antenna module 207 and a second antenna module 208, and each antenna module may be a single antenna or an antenna array...
Embodiment 3
[0099] Embodiment three: implementation mode 1
[0100] Such as image 3 shown, showing the figure 2 The internal structure diagram of the first modem module 2041 and the second modem module 2042 shown in , and how the first modem module 2041 and the second modem module 2042 are Obtain the LTE band information that needs to be searched for respectively, and instruct their corresponding radio frequency units and antenna modules to search the network. image 3 The first radio frequency unit 205 and the second radio frequency unit 206 are respectively connected to an antenna module.
[0101] The first modem module 2041 and the second modem module 2042 may respectively include a NAS layer, an RRC layer and a PHY layer. The first modem module 2041 is the main modem module on the UE, which may also include MTC, and the MTC (Multi-Terminal Control multi-mobile terminal control module) is a part of the main modem module for Communication between primary and secondary modem module...
