What is peer-to-peer information?

Peer-to-peer SMS refers to the business form of sending and receiving SMS between mobile phones. The forms of peer-to-peer short messages include intra-network short messages, inter-network short messages and international short messages. Point-to-point SMS is an independent user communication tool in theory. The communication tool can be a mobile phone, client software, PDA, etc. But no matter what point it is, the most basic purpose of point-to-point SMS is to realize two or more points of mutual communication, which is what people usually call chatting. The basic function of point-to-point SMS service is chat, which can be divided into point-to-point chat, industry/enterprise application (in essence, one-to-many points), self-writing SMS, inter-network interoperability, international interoperability and so on. As a brand-new and relatively independent way of interaction, SMS has become another way for people to obtain information. With the deepening of short message culture, point-to-point short message has become one of the main ways for people to chat remotely. Peer-to-peer SMS combines the characteristics of convenient use, wide range, storability and forwarding of mobile phones, and has the advantages of low price and no loss of information when turned off. It is short and pithy, convenient and quick, and can be said to be an "electronic note". At present, SMS is the only service in GSM network and CDMA network that does not need to establish an end-to-end service path, and it can be transmitted even if the mobile station is in a complete circuit communication state. Short message communication is limited to one message, in other words, the transmission of one message constitutes a communication. Therefore, the service is asymmetric, and it is generally believed that the initial mobile SMS sending and the mobile terminal SMS sending are two different things. This does not hinder real-time communication, but the system thinks that different messages are independent of each other, and the transmission of messages is always relayed by the Short Message Service Center (SMSC) outside GSM. Messages have destinations or origins, but they are only related to users and SMSC, and have nothing to do with other GSM infrastructures.
