A kind of method to PHS mobile phone lock network and burning number

Technical field

The invention belongs to moving communicating field, specifically is a kind of method that the PHS mobile phone is networked and limits.

Background technology

At present, PHS operator need carry out various advertising campaigns for the ownership, mainly is exactly price supporting policy wherein, as is lower than the mobile phone purchasing price and sells the user mobile phone, perhaps hands over telephone expenses to send mobile phone etc.The user can or freely obtain mobile phone with very low price like this.Part PHS mobile phone distributors may obtain mobile phone at a low price by certain regional operator, forward then other area to and sell at high price, thereby earning operator is the subsidy that developing market carries out.Operator need to limit the networking of this subsidy mobile phone for this reason, hope is limited to this mobile phone in the local network and uses, the use that can not again network in other place, and burning number is used again in this locality, yet, the convenient, flexible method that does not address the above problem at present.

Summary of the invention

The present invention will solve in the prior art technical problem that can't network and limit mobile phone.

The invention provides a kind of method to PHS mobile phone lock network, may further comprise the steps: after mobile phone enters the burning number pattern, cell phone software is received and is resolved this read write command after burning number software is to the read write command of memory, by cell phone software memory is read and write, write the burning number data by burning number software, it is characterized in that, after burning number software writes the burning number data, write lock network sign and lock network length mark.

Described method to PHS mobile phone lock network, wherein, the described lock network sign that writes refers to an address bit of memory is defined as the lock network flag, sets the lock network sign by burning number software in this flag.

A kind of method to the number of burning of PHS mobile phone may further comprise the steps:

3.1 after mobile phone entered the burning pattern, cell phone software judged at first whether mobile phone is in the lock net state;

3.2 if mobile phone is in the lock network state, then do not respond burning number software to the read-write of memory, turn to step 3.3, if mobile phone is not in the lock network state, turn to step 3.4;

3.3 the length according to lock network length mark position indication on the memory, the top N that reads the top N of the fuselage code that write last time and will again write fuselage code compares, and if the same according to writing order the burning number data is write, do not write order otherwise do not respond, burning number finishes;

Resolve this read write command 3.4 receive burning number software after to the read write command of memory, and memory is read and write, write the burning number data by burning number software.

Described method to the number of burning of PHS mobile phone, wherein, step 3.1 further may further comprise the steps:

4.1 determine that an address bit of Electrically Erasable Read Only Memory is the lock network flag, an address bit is lock network length mark flag;

4.2 when mobile phone entered the burning pattern, cell phone software at first read the lock network mark and knows the position;

Whether erect 4.3 judge this flag, if this sign erects, then this mobile phone, otherwise be in not lock network state if being in the lock network state.

Described method to the number of burning of PHS mobile phone, wherein, step 3.4 further may further comprise the steps: cell phone software response external read write command, burning software writes the burning data; Judge whether to need the lock net,, burn and number finish if then write lock net length mark and lock network mark will; If do not need to lock net, then burn and number finish.

The PHS mobile phone of employing this method can be in the needs lock network, as long as when writing code, write former length and the lock network sign of the number that will lock, after writing lock network sign and lock network length mark, when mobile phone is write yard again, length such as N according to lock network length mark flag sign on the memory, read the top N of the PSNUM (fuselage code) that write last time, compare with the top N of the PSNUM that will again write, if the same carry out and write order, do not write order otherwise do not respond.If the disabled user adopts Flash-writer to the memory direct control, then can be because of cell phone mainboard device density height, need to open the reason such as casing, cause easily mobile phone to damage, and operation inconvenience, therefore be unfavorable for cracking by force.So just can be locked mesh preferably.

Embodiment

To PHS mobile phone burning the time, the PHS mobile phone can enter a special pattern, and industry is called " TestMode " (being test pattern or burning pattern).After entering this pattern, cell phone software brings into operation, and when receiving burning software to memory, described memory can be eeprom (Electrically Erasable ﹠amp; Programmable ROM, Electrically Erasable Read Only Memory), also can be other storage medium.When carrying out read write command, cell phone software can be resolved burning number software read write command, and by cell phone software memory is carried out reading writing working according to analysis result, returns then the state of read-write; In this way, burning number software just can in the predetermined parameter read-in mobile phone, be finished the code work of writing to mobile phone.As shown in Figure 1, in order to lock net, we can be defined as locking network mark to the address bit of eeprom and know the position, an address bit is defined as locking net length mark sign position, when mobile phone enters the burning pattern, cell phone software at first reads the lock network mark and knows the position, (as the sign position is to be set in 1 o'clock to erect to judge whether this sign position erects, other is not for erecting), if this sign erects, then do not respond burning software the lock network mark of eeprom is known the write command of position and lock net length mark sign position, otherwise response burning software is to the read-write of eeprom, finish read-write operation, make correct feedback memory.If lock network mark will erects, according to memory the lock length such as the N of net length mark sign bit-identify, read the preceding N position of the PSNUM that write last time, compare with the preceding N position of the PSNUM that writes once more, if it is identical then burning data are write according to write command, otherwise do not respond write command, and number failure is burnt in prompting.

Usually, if not the lock network burning number, after the burning number data are write, just point out burning number success or failure, do not write lock network flag and lock network length mark.And if lock net burns number, not only the burning data of routine are write, also write lock net length mark and lock network mark will, and then prompting burning success or failure.The meaning that writes lock net length mark is: the layout of general PSNUM somewhere is that the area code beginning with this locality adds the serial number layout, and area code has 3 and 4, the user can select the scope of the PSNUM section that will lock as required like this, the PSNUM that writes as the first time is 055101234567, lock net length mark is designated as 4, then this mobile phone can only write number section of 0551 beginning once more, and promptly lock net in whole city is lost to the just number of the burning use again again of other city; If writing lock net length mark is 8, so just can be locked as the PSNUM of 05510123 beginning to number section, i.e. zone lock net.

As shown in Figure 2, be another execution mode flow chart of realizing that PHS cell-phone lock net burns number.Wherein, mobile phone is when entering the TestMode state, burning software sends read write command to mobile phone, mobile phone is resolved after receiving the read write command of sending the outside, judge whether lock network mark will erects, if lock network mark will erects, referring to Fig. 1, then do not respond burning software the lock network mark of eeprom is known the write command of position and lock net length mark sign position, then according to memory the lock length such as the N of net length mark sign bit-identify, the preceding N position of reading the PSNUM that write last time, compare with the preceding N position of the PSNUM that will write once more, if identical then according to write command burnings data are write, otherwise do not respond write command, and prompting is burnt and number is failed.The instruction of normal response exterior read-write writes the conventional burning number data such as authentication code if the lock network sign does not erect, and need to judge whether then lock network, if it is writes lock network length mark and lock network sign, and burning number is finished.If do not need to lock net, then normal the burning number finished.With the PHS mobile phone of lock network sign, after restarting, when again entering the TestMode state, will identify to judge whether the response number of writing order according to the lock network length mark, response external is not to the write operation of lock network flag and lock network length mark flag; And the mobile phone that does not have the lock network sign can be write code again; Because the PHS mobile phone can not be roamed at present, if will arriving in the another one network, uses by a mobile phone, burning number again just, could use after writing the data of this network, in case mobile phone can not be write code again, this mobile phone can only use in the place that networks, and just can be good at reaching the purpose of lock network.

In sum, when resolving outside read write command to memory, cell phone software can judge the state of lock network mark will, if be designated the lock net state, cell phone software does not just respond the write operation to lock network mark will and lock net length mark, guarantee to lock the purpose of net, analyze scope (by existing PSNUM and lock net length mark sign) that whether content will write PSNUM meet the lock net then whether decision responds and burn number order.If there is not the lock indication net state, then can responds the burning number order and write the lock network sign and the order of lock network length mark.
