What is GPRS? What does it have to do with MMS?

Answer: GPRS is the abbreviation of General Packet Radio Service, and it is a new packet data bearer service. The fundamental difference between GPRS and existing GSM voice system is that GSM is a circuit-switched system, while GPRS is a packet-switched system. Therefore, GPRS is especially suitable for intermittent, sudden or frequent, small data transmission, as well as occasional large data transmission. This function is suitable for most mobile Internet applications.

What is the relationship between MMS and GPRS?

MMS is a WAP service based on WAP wireless application protocol, which transmits pictures, sounds, words and other information. WAP can be transmitted through GPRS network, of course, it can also be transmitted through the original circuit-switched (CSD) mode, but because GPRS adopts packet-switched network, the data transmission rate is faster than that of circuit-switched (CSD) mode. Therefore, MMS is a new application service on GPRS network. If you use GPRS to transmit MMS, sending and receiving MMS will generate GPRS traffic.

If GPRS is a wider road than CSD, WAP is a car running on the road, and some of these cars have added functions such as listening to radio and watching TV, then these cars with new functions are MMS. These cars with new functions can run GPRS or CSD, but it is certain that GPRS will make these cars run faster. In order to let people hear the radio and see the telecom in the car, we have laid some new facilities near the road, which are just some new network devices that transmit multimedia messages on the network.

What are the advantages of GPRS?

Compared with the original GSM dial-up circuit-switched data transmission mode, GPRS packet switching technology has the advantages of "real-time online", "quantity charging", "fast login", "high-speed transmission" and "free switching".

Real-time online

"Real-time online" means that users keep in touch with the network at any time. For example, when a user accesses the Internet, a mobile phone sends and receives data on a wireless channel. Even if there is no data transmission, the mobile phone remains connected to the network. Users can not only initiate data transmission, but also start push service at any time from the network side, unlike ordinary dial-up Internet access, which requires redialing to access the Internet.

Charge by quantity

Users can charge online at any time according to the number of packets sent and received. When there is no data traffic, users will not charge even if they hang up and surf the Internet. Give a very vivid and interesting example: it is free to be in a daze.

Quick login

Once GPRS users are turned on, they are always connected to the GPRS network. They only need an activation process every time they use it, and it usually takes 1~3 seconds to log on to the Internet immediately. However, fixed dial-up internet access requires dialing, verifying user name and password, logging in to the server and other processes, which takes at least 8~ 10 seconds or even longer.

high-speed transmission

GPRS adopts packet switching technology, and the highest theoretical data transmission rate can reach 17 1.2kb/s, but the actual speed is limited by coding and mobile phone terminals, which may be different. The rate of circuit-switched data service is 9.6Kbits per second, so the relationship between circuit-switched data service (CSD) and GPRS is just like the difference between a 9.6k modem and a 33.6K or 56K modem.

Free switching

GPRS also has the advantage that data transmission and voice transmission can be conducted or switched at the same time. In other words, users can use their mobile phones to surf the Internet while answering voice calls. For example, the original telephone dial-up internet access, after access, can not make calls, can not answer the phone, and GPRS is similar to the concept of fixed telephone ISDN, telephone internet access is correct. Compared with the original GSM dial-up circuit-switched data transmission mode, GPRS is a packet switching technology with the advantages of "high speed" and "always on".

1. What is MMS?

Answer: MMS can't be received when the phone is turned off or out of service area, but it will be kept in the system for 48 hours. Once turned on or entered the network service area within 48 hours, the MMS mobile phone can still receive MMS normally. If the mobile phone is not turned on or is still out of service within 10 minutes, the system will forward the multimedia message to the receiving user's Monternet mailbox while retaining the multimedia message, and the user can still receive the multimedia message when logging in to Monternet mailbox.

5. How much is the MMS service?

A: Commonly used MMS can be roughly divided into two categories:

(1) Point-to-point MMS: 0.90 yuan/piece (maximum capacity of each piece is 50K), the sender pays, the receiver is free, and both parties will not charge GPRS traffic fee; 0.5 yuan/piece of communication fee during the current preferential period.

(2) SP MMS: Request and subscribe to MMS from the cooperative service provider (SP): The information fee is set by SP, and both parties will no longer charge GPRS traffic fee.

6. Do I need to apply for MMS service?

A: There is no need to open the MMS service function separately, but customers must open the GPRS function to use MMS. At this stage, you may encounter the situation that the new MMS mobile phone cannot use SP MMS. The main reason is that the new MMS mobile phone users are still unknown users in the network before the first use. There are three solutions:

Users send MMS from MMS mobile phone to any other mobile phone number or any email address, or other users send MMS to the user (it is suggested that 1860 personnel help to send any MMS to the user).

Users log in to www.monternet.com MMS user self-service system to modify user status. 1860 personnel log in to the MMS user service system to help users change their status to "MMS user".

7. Is there an extra charge for domestic roaming MMS service?

8. How to use MMS service?

Answer: The MMS service can realize multiple functions, and its specific uses are as follows:

The MMS mobile phone sends a photo or MMS saved in the MMS mobile phone to the MMS mobile phone user. To send to other mobile phone users, please select this multimedia message, then select Send to mobile phone number, enter another mobile phone number, and then send. Under normal circumstances, the receiving user can directly receive the multimedia message. However, if the receiver's mobile phone cannot receive this multimedia message within 10 minutes * due to reasons such as power off, out of service area, being on a call, etc. , the network will transfer this multimedia message to the recipient's Monternet mailbox. 10 minutes later, once the recipient's multimedia message phone has the reception conditions, it will still receive this multimedia message. However, if the recipient's MMS mobile phone still does not receive the MMS within 48 hours of validity, the system will delete the MMS, and the user can only log in to Monternet mailbox through the URL address, user name and password sent by the email arrival notification to extract the MMS.

MMS sent by mobile phone to ordinary mobile phone users If you want to send MMS to ordinary mobile phone users, because the receiving user's mobile phone cannot receive MMS, the system will automatically forward MMS to the receiving user's Monternet mailbox and send SMS notification to the receiving user. The receiving user can receive this multimedia message after logging in to Monternet mailbox.

MMS mobile phone sends a photo or saved MMS to a mailbox, selects this MMS, then sends it to the mailbox, enters the other party's mailbox, and then sends it. The recipient user can log in to the mailbox to receive the multimedia message. If the mailbox of the recipient user is the Monternet mailbox of China Mobile, the Monternet mailbox system will send a short message notification to the recipient user in the form of mail arrival notification when receiving this multimedia message.

Send MMS from Monternet mailbox. After logging into Monternet mailbox (mail.monternet.com) on the Internet, mobile phone users choose to send MMS. The receiver inputs the other party's mobile phone number, takes the multimedia message as an email attachment and chooses to send it. If the receiving user is a MMS mobile phone, it will be received in the form of (1). If the receiving user is not a MMS mobile phone, the system will reject the MMS sent by the Monternet mailbox user and notify the Monternet mailbox user by SMS.

Download Monternet MMS from the website to your mobile phone. Users can customize Monternet MMS from Internet websites and send it to MMS mobile phones. The process of customizing and on-demand is similar to customizing or on-demand Monternet SMS. Users need to register their mobile phone number on the website, select Monternet MMS to download, enter the mobile phone number to send and then send it.

For example, send it to Sina, and the sending number is 8888. (For specific usage, please refer to the business instructions on each SP website. )

9. Can I still receive MMS when I make a phone call?

Answer: No, because MMS is transmitted through GPRS or CSD. At present, MMS or GPRS is a class B mobile phone of GPRS, so it is impossible to transmit data at the same time when making a phone call and receiving a phone call. But once the phone hangs up, you can still send and receive MMS normally.

10. If it is not a MMS mobile phone, can the other party receive the MMS sent by the user?

A: Yes. If it is a MMS mobile phone, you can receive MMS directly from the mobile phone. However, if the recipient is not a MMS mobile phone, the system will automatically forward the MMS to the recipient user's mobile Monternet mailbox, and the recipient user can still receive the MMS by logging in to the mobile Monternet mailbox.
