Abstract
The utility model relates to a pocket telephone, which is called Xiaolingtong usually. The utility model comprises a power supplier, a display screen, a baseband chip, a key field, a radio frequency module and an antenna, wherein, the radio frequency module, the antenna, a flash memory and a static memory are respectively connected with the baseband chip. The key field sends an instruction which is transferred to the baseband chip, and the baseband chip controls the display screen, the flash memory and the static memory. At most eight groups of system parameters are stored in the component with a storage function connected with the baseband chip, which is used for searching the system parameter of the roaming place to overcome the defect that the roam can not be realized at the place far away from home because the pocket telephone just stores a group of system parameters at present.
Description
Technical field
The utility model relates to a kind of portable phone, and promptly common alleged " Personal Handyphone System " relates in particular to a kind of portable phone of roaming.
Background technology
Portable phone PAS (Personal Access Phone System) is a kind of novel individual radio connecting system, it adopts advanced microcellulor technology, insert fixed-line telephone network wirelessly, make traditional phone in the scope that wireless network covers, can carry use, answer whenever and wherever possible, dial indoor, local network and domestic, overseas call, also can dial paging and mobile phone easily, be the extension of local telephone and replenish, promptly we alleged at ordinary times " Personal Handyphone System ".
Along with portable phone developing rapidly throughout the country, the demand of roaming between different cities becomes more and more urgent.But because the historical reasons of PHS system development, the system parameters of different cities exists difference, and these parameters comprise: control channel frequency, operator code, and country code.At the initial stage of networking, owing to lack unified planning, different manufacturers has adopted different system parameterss, to such an extent as to there are several cover system parameters in a province.Calendar year 2001 department of China Telecom issue is expressly provided, newly-built PHS network must use the fixing system parameters of a cover after requiring, but the fixing system parameters of this cover is different from former parameter again, and since at present the PHS mobile phone adopt the method for No. one, a machine, after in case mobile phone is opened an account, system parameters just is fixed, and the user has arrived the city of different system parameter, and mobile phone can't find network at all.Therefore in order to support the roaming between the various places, press for a kind of new portable phone and solve the inconsistent problem of different cities system parameters.
Summary of the invention
The purpose of this utility model is to provide a kind of portable phone that can roam in different cities.For achieving the above object, the utility model has adopted following technical scheme: a kind of portable phone, comprise power supply unit, display screen, baseband chip, keypad, radio-frequency module, antenna, radio-frequency module, antenna, flash memory, static memory is connected with baseband chip respectively, send baseband chip to by sending instructions by keypad, again by the baseband chip control display screen, flash memory, static memory, portable phone can be established 8 group system parameters at most, this 8 group system parameter is stored in portable phone flash memory and the static memory, every group of parameter comprises: control channel frequency, operator code, and country code.The first group system parameter is the ownership place parameter, is the group of portable phone first search, and the other system parameter group is the roaming place parameter.
Owing to store maximum 8 group system parameters in the memory of portable phone, portable phone can be according to different system parameters search networks, and realize roaming function.
