The method, the system and the application gateway of the invention realize the receiving and / or sending of the short messages in the 'same number' service andare propitious to realize a complementary advantage between a main-number network system and a sub-number network system.

Description

technical field [0001] The invention relates to a method, system and application gateway for receiving and sending same-number service short messages, belonging to the communication field. Background technique [0002] When the fixed-line telephone communicates through the Public Switched Telephone Network (hereinafter referred to as PSTN), the call quality of the fixed-line telephone is well guaranteed due to the use of a dedicated communication line. Personal hand-held phones, commonly known as "Personal Handy-phone Systems", adopt digital micro-cellular technology and are positioned as supplements and extensions of fixed-line phones. A service for mobile calls within the local area.

Problems solved by technology

[0003] In the prior art, landline telephones and personal hand-held telephones have respective advantages, but also have their own defects: the conversation quality of landline telephones is higher, but due to the The large line dependence greatly limits the mobility of users; personal handheld phones can realize mobile calls in the local area, but the network coverage area is limited, making the call quality of users outside the network coverage area poor or even unable to communicate normally

However, the same-number service only realizes the same-number service of the voice call, and cannot realize the same-number service of the short message service
