In a mobile communication system including a mobile station, an access apparatus for performing connection control between the mobile station and an access network, and an access network switching apparatus for switching access networks to communicate with the mobile station, the mobile station establishes a first path to communicate with the access apparatus, when the mobile station enters a coverage area of the access apparatus. The access apparatus establishes a second path to communicate with the access network switching apparatus when the first path is established. The access network switching apparatus switches the access networks when a predetermined condition is satisfied.

摘要:
A communications system is provided which can search for information about a communications device that is not registered in a network by designating time. The search system, which includes a plurality of communications devices, gateways and an entity management server, can execute a search method. The entity management server stores in a storage device the identification information of the communications device sent from the gateways with establishing correspondence with notification time. The entity management server receives from a mobile terminal the identification information of the communications device and designated time. The entity management server searches for the identification information stored in the storage device at the designated time, and identifies the location information of the gateways corresponding to the identification information included in the search request.

A communication system according to the present invention includes: a mobile station 10; an access point located on a radio access system; and a switch apparatus 30 connected to the radio access system, wherein a secured connection between a mobile station 10 and the access point 20 has been already established. The mobile station 10 includes a judgment unit 30 configured to judge whether or not to establish a secured connection between the mobile station 10 and the switch apparatus 30.

A CSFB processing unit (14) of a mobile switching center (MME) of according to the present invention is configured not to perform CSFB processing to enable a mobile station (UE), which establishes a bearer in a core network of a mobile communication system of the LTE scheme, to start CS communication in a mobile communication system of the WCDMA scheme, when CS communication of the mobile station (UE) in the mobile communication system of the WCDMA scheme is restricted in a specified area, even when the mobile switching center (MME) of the mobile communication system of the LTE scheme detects that a service request signal transmitted by the mobile station contains the first identification information.
摘要:
A radio communication system includes an EPC 100, a 3G network 200 and a mobile station 10 connectable to an external network 300 via any one of the EPC 100 and the 3G network 200. The communication system includes: a handover function unit configured to control a handover from the EPC 100 to the 3G network 200. The number of EPS bearers allowed to be set up with the mobile station 10 and the EPC 100 is larger than the number of PDP contexts allowed to be set up with the mobile station 10 and the 3G network 200. The handover function unit controls the handover in accordance with the number of the EPS beaters already set up with the mobile station 10 and the EPC 100 and the number of the PDP contexts to be newly set up with the mobile station 10 and the 3G network 200.
摘要:
A location registration method according to the present invention, includes: transmitting, at a mobile station (UE), a TA signal, when detecting that the mobile station (UE) has moved out of a TA list with which the mobile station (UE) is already registered by location registration processing; and transferring, from a radio base station (eNB) to an exchange (MME) identified by an exchange ID included in the TAU signal. An exchange ID assigned to a mobile station (#a) belonging to a first layer is different from an exchange ID assigned to a mobile station (#b) belonging to a second layer, even though the same exchange is identified by the exchange IDs. A TA list and a pool area set for the mobile station (#a) is different from a TA list and a pool area set for the mobile station (#b).
