摘要： To solve the problem with mobile phone carriers that increasing mail traffic increases storage capacity of a mail server and network load, a relay server which relays a mail transfer (SMTP communication) and a mail fetch (IMAP communication) is installed in a carrier facility network. The relay server compresses a mail including a header transferred from a mail transfer server, adds a new header to encapsulate the mail, and transmits the encapsulated mail to an IMAP server as a compressed mail. In response to a mail fetch request from a communication terminal, the relay server decapsulates and restores the compressed mail fetched from the IMAP server, and transmits the restored mail to the communication terminal. The relay server changes parameters such as the mail size, so that no inconsistency of IMAP commands occurs in compressing/restoring the mail.

摘要： In order to reduce network loads in a large system, provided is a representative aspect of this invention is as follows. That is, there is provided a SIP server coupled to at least one client via a communication line to control a communication session of the at least one client. The SIP server receives a SIP message transmitted from the at least one client, transfers the received SIP message to one of another SIP server and another one of the at least one client, and analyzes the received SIP message. The SIP server comprising a storage unit for storing a result of the analysis. The SIP server compares the result of the analysis and a SIP message received after the analysis, rewrites the SIP message based on a result of the comparison, and changes a transfer destination of the SIP message based on the result of the comparison.

摘要： In a large-scale mail system such as that of a mobile phone carrier, in case that a mail gateway has encountered a fault due to a fault-inducing mail in arrival thereat, the mail gateway identifies the cause of the fault to prevent the recurrence thereof. The mail gateway is configured to include a mail relaying process used for relaying mails and a monitoring process used for supervising other processes. On occurrence of a fault due to a fault-inducing mail received by the mail relaying process, the monitoring process detects the fault-inducing mail that has cause the fault, the characteristics of the fault-inducing mail and the conditions of the fault, and then records information thus detected into a fault-inducing mail information table. After recovery from the fault under control of the monitoring process, the mail relaying process receives a new arriving mail. Upon receipt of the new arriving mail, the mail relaying process compares the characteristics thereof with relevant information recorded in the fault-inducing mail information table. If a match is found, the mail relaying process performs one of three countermeasures according to the conditions concerned; skipping over a faulty-point processing, returning an error reply to a mail transmission source, or returning a notification of non-delivery thereto.
