hand, when the base station was installed, the workers were not sure about the rigorous attitude when determining the longitude and latitude of the base station. On the other hand, it is not sure whether mobile operators are willing to publish the longitude and latitude of each base station. How to obtain the longitude and latitude of the current mobile phone location seems to be difficult to solve. Let's take a step back and think about whether the location service is inseparable from the long

Wireless Internet card refers to wireless WAN card, connected to the Wireless wide area network, such as TD-SCDMA, China Telecom CDMA2000, CDMA 1X and the WCDMA network. It can be connected to the Internet using a Usim or SIM card anywhere it has a wireless phone signal coverage. The function and function of wireless Internet card is like a wireless modem. Its common interface type also has PCMCIA, USB, Cf/sd,e,t and so on. Wireless Internet card is

Wireless Internet card refers to wireless WAN card, connected to the Wireless wide area network, such as TD-SCDMA, China Telecom CDMA2000, CDMA 1X and the WCDMA network. The function and function of wireless Internet card is equivalent to wired modem, which is called "cat". It can be connected to the Internet using a Usim or SIM card anywhere it has a wireless phone signal coverage. The function and function of wireless Internet card is like a wireles

, so the location accuracy of urban cell_id is far higher than the suburbs and rural areas. The CDMA system does not need to set the dense base station, the urban area radius is generally around 1-2km, at this time the cell_id precision is not superior to the 500m, such precision can not satisfy most user's request. Therefore, some improvement techniques, such as Cell_id+sector-id, Cell_id+ta and Cell_id+rtt technology, have appeared on the basis of cell_id, although these technologies can impro

Customer network node of the line voice (such as private network voice trunk), 2M digital circuits, broadband IP internet access, DDN and other services integrated access. 3.1.5 MSTP applied to future 3G network The mainstream of 3G mobile communication includes WCDMA, CDMA2000 and TS-CDMA, among which WCDMA has the most kinds of transmission interfaces, including STM interface, ATM interface, IMA interfac

attacks against other computers on the network. Rootkit is usually Organized into a group of tools that are refined into specific operating systems. The first Rootkit was identified in 1990s, when Sun and Linux Operating systems are their main attack objects. Currently, Rootkit can be used in many operating systems, including Microsoft? Windows? Platform. Note: Please note that RAT and some tools containing Rootkit have valid remote control and monitoring usage. However, the security and confid

5 monetization strategies of mobile edge computing (MEC), monetization of mec Mobile edge computing (MEC) has five monetization strategies. In the past few years, cloud services have been unable to compute the large amount of data generated by mobile devices and provide meaningful analysis, this is true even at the speed of light. This is because the distance between the cloud and the device through the return operation causes delay, which is a problem that mobile edge computing (MEC) solves. ME

variety of digital content and video services, thus increasing revenue. The WebLogic SIP server provides required call establishment and session management. However, carriers still need advanced media processing capabilities and standard interfaces that can interwork with BEA solutions, this allows carriers to provide scalable voice, video, and multimedia services. They also need a media gateway for cross-

The development of WiMax technology also puts forward higher requirements for receiving and transmitting tests corresponding to WiMax physical layer tests. R S provides targeted testing solutions. WiMAX is called World Interoperability for Microwave Access. It is a wireless MAN technology ), A base station can provide a maximum downstream data transmission rate of Mbps for multiple fixed users within a 3-10 km radius, and provides a maximum downstream data transmission rate of 15 mbps for multi

create new revenues through new technologies and services such as VoIP, multimedia Short Messages (MMS), and 3G. Integrated billing simplifies settlement between carriers and customers, as well as between carriers and partners. It can seamlessly support various network traffic on a single platform, regardless of whether they come from voice, data, or IP/next-generation services. In a content-based service

Both China Mobile, China Unicom, and China Telecom provide at least two types of APN: WAP and net. Among them, the net method is the same as the WiFi method, without any settings, You can freely access all types of websites, and the WAP method requires the mobile phone to first set proxy server and port number information, you can only access websites of the HTTP protocol type. 1) The Mobile WAP name is cmwap and the net name is cmnet; 2) China Unicom's WAP name is uniwap, net name is uninet, Ch

According to a survey conducted by Ovum, a well-known research firm in the market, the rapid growth of mobile broadband traffic has prompted operators to consider problems other than the negative benefits of Wi-Fi. However, even though Wi-Fi traffic is being increasingly integrated into most operators' infrastructure strategic plans, carrier-level solutions cannot fully meet operators' needs. According to the survey, many operators are still looking for features that are not suitable for large-

better the quality of VoIP calls. For example, high-speed broadband connections allow you to make a phone call while surfing the Internet. You also need VoIP software. You can choose to install a VoIP software on a desktop or laptop. Then, the computer can make online calls. If you want to convert your home phone to a VoIP dialing system, you need help from the adapter. VoIP software can be independently pre-installed on a hardware device named "analog Phone adapter" analog telephone adapter).

address of the route to the VPN-IPv4 address. Specific route information that is distributed includes the VPN-IPv4 address prefix for the route, the next hop BGP is the VPN-IPv4 address of the entry PE router where RD = 0) the VPN label assigned to the route and the Export rt in the vrf table of the route. This routing information is known as the VPN-IPv4 routing information with labels. When the egress PE router receives the route information, it will view the RT of the route, if RT matches an

It is recommended that serum HBSAG, anti--HBC and anti--HBS tests be performed on patients ' family members and other close contacts, and hepatitis B vaccine is administered to susceptible persons (the 3 markers are negative).For patients with acute or chronic hepatitis B, it is possible to determine whether they are hospitalized or treated

Problem:1. Resource particle Re, used (k,l) to identify the coordinates of the time domain in the frequency domain, how to understand. A: K is the number of the sub-carrier of the resource raster, L is the SC-FDMA ordinal in the time slot 2. A RB has n time-domain continuous SC-FDMA symbols and a continuous sub-carrier composition in the frequency domain. What a SC-FDMA symbol refers to. is the number 0 or 1. or a modulator (for example, 8-in modulation, 8-frequency shift keying, this symbol is

Text, numbers, language, informationnumbers, words and natural languages are the carriers of information, and they are created to record and disseminate information .But it seems that the relationship between mathematics and linguistics is not big, for a long time, mathematics is mainly used in astronomy, mechanics.In this chapter, we will review the development of the information age and see how linguistics is slowly associated with mathematics.Infor

Recently, has been studying, default APN settings When we see from the code and the phone, the default APN display is from the CONTENT://TELEPHONY/CARRIERS/PREFERAPN data, and this is saved through the shared preference, when the first time the phone card boot, After we have preferapn.xml the file, we find that it has been written with a value, but from the Telephonyprovider.java file, we do not find any written place, then the default APN exactly how
