摘要:
A call relay system includes: an outgoing call terminal; an incoming call terminal; and a call relay device which relays a call from the outgoing call terminal to the incoming call terminal. The call relay device includes: a relay section which relays the call from the outgoing call terminal to the incoming call terminal, correlates a telephone number of the outgoing call terminal indicated by the call with a telephone number of the incoming call terminal indicated by the call and registers call history information including the telephone numbers of the outgoing call terminal and the incoming call terminal in a call history storage section; a receiving side report acquisition section which acquires, from the incoming call terminal, a receiving side report indicating an evaluation attribute regarding the call; and a call attribute setting section which acquires, from the call history storage section, the call history information regarding the call indicated by the acquired receiving side report, correlates the evaluation attribute indicated by the receiving side report with the telephone numbers of the outgoing call terminal and the incoming call terminal included in the acquired call history information regarding the acquired call and registers the correlated information in the call attribute storage section.
摘要:
In order to save energy in EPS network, some of the MMEs and/or S-GWs are allowed to sleep (power down), when network's traffic load is decreased. When the traffic load becomes heavier, the network can power up some of the formerly sleeping MMEs and/or S-GWs.
摘要:
A mobile communication system for relaying user data includes a plurality of base station apparatus and a core network apparatus. Each of the base station apparatus forms a cell for connecting to a terminal through a wireless link. The core network apparatus can be connected to the base station apparatus. Even when the terminal moves between the base station apparatus while the terminal is in an active mode in which the terminal is communicating, the core network apparatus which is connected to the terminal keeps itself connected to the terminal.
摘要:
A communication method in LIPA/SIPTO architecture is provided which, when a user equipment (UE) is to connect from a serving area to an external network, allows re-selection of an optimal gateway. The communication method allows selecting a gateway apparatus physically or topologically close to a site, where the user equipment is attached.

A protection against an unsolicited communication for an IMS (PUCI) system includes a call session control function (CSCF), and a plurality of PUCE application servers. The PUCI application servers make an evaluation as to whether a communication received from the user equipment is an unsolicited communication; the CSCF makes a decision on routing toward the PUCI application servers based on the evaluation; then, the PUCI application servers execute the routing based on the decision.
