GSM is a 2G network and can be used by China Mobile Unicom.CDMA is a 2G network of China Telecom. 3G:WCDMA is China Unicom's 3G network,China Telecom 3G is CDMA 2000,China Mobile 3G is 3g/TD-SCDMA. Both of them are networks that are also supported by foreign countries. That is to say, if you have a mobile phone with this network standard and the software is unlocked, you can use it directly on a foreign card! The third type is China's self-develope

[Exclusive disclosure !] Let the USIM card of TD-SCDMA work in GSM network way! Use a machine supporting 3g wcdma, insert the td usim card, and switch the network selection mode of the 3G mobile phone to the automatic mode. The test was successful on Toshiba g500. The Nokia N95, which is widely used on the Internet, can be recognized or used as a credential. The N95 is a WCDMA support. Cause and analysis: Next time, all the content just writte

/* Hdu 4643 GSM computing Ry-point-line relationship N cities, any two cities have A railway M base station along a straight line between them. Ask how many times A base station needs to be switched from City a to City B. When A base station is switched from base station a to Base Station B, the switchover location is the intersection of the AB center vertical line and the railway (which of the two base stations can be easily switched, sort by distanc

At present, most enterprises and schools are built intranet. and built internal Web site to achieve resource sharing. In order to make users know the latest information on the Internet, many websites have adopted the way of SMS reminder, but using China Mobile or Chinese Unicom SP Way, will greatly increase the cost of the enterprise. Therefore, this article discusses the use of GSM modem and SMS send control to achieve SMS reminders. First of all, i

disk performance warning: SQL Server has encountered occurrence (s) of I/O requests taking longer than [seconds] on file [F:\sqldata\ LOGS\XXXX_LOG.LDF] in database [XXXX] (10). The OS file handle is 0x0000000000000a2c. The offset of the latest long I/O is:0x000004e6511e00 By collecting disk performance information, we found that at the point of the problem, Avg. Disk Sec/read reached 1.444. Usually this value is about 0.03 more normal. The value of 1.444 is obviously quite biased. ConclusionNe

interceptors (Intercept): As with the Struts2 interceptor mechanism, it is an operation that passes through a layer of interceptors, each of which triggers the event of the appropriate interceptor for preprocessing or aftercare.　　Listener (Listener): In fact, the function is similar to the interceptor, but its implementation principle is different, it is to regis

When configuring a package, you can specify the default interceptor for it. Once a default interceptor is specified for a package, if the action in the package does not explicitly specify the interceptor, the default interceptor will take effect. Note: once an interceptor is

SpringMVC-detailed interceptor process, use and customize interceptor First, let's look at what the interceptor does: 1. Logging: records the request information logs for information monitoring, information statistics, and calculation of PV (PageView. 2. Permission check: for example, if logon is detected, go to the processor check to check whether or not to log

First, Interceptor method The EJB3 can intercept and overwrite bean methods through interceptors. This is somewhat like the around in AOP. The around method of AOP can modify the return value, parameter value of the blocked method, and even cancel the execution of the blocked method. EJB3 interceptors can be used in stateless session beans, stateful session beans, and message-driven bean (MDB) methods. The easiest way to implement interceptors is to
