Abstract:
Embodiments of the present invention disclose a method, an apparatus, and a system for controlling network access of a machine terminal. In the embodiments of the present invention, an authorized period and/or a forbidden period of a time-controlled subscription is generated according to information such as network service load historical data of a network and application information of the time-controlled subscription. Network access of the machine terminal is controlled according to the authorized period and/or the forbidden period. Because the network access time of the machine terminal can be controlled flexibly, the communication of the machine terminal can be controlled flexibly, and impacts of machine terminal communication on ordinary terminal communication can be reduced.
Abstract:
A method and apparatus for service control in which a service centralization and continuity application server (SCC AS): receives a first SIP message for establishing an IMS centralized service session; receives early session media information; and sends a second SIP message carrying the early session media information to a media gateway control device. The early session media information is carried in the second SIP message in a form of regular session media information, thus the media gateway control device uses an existing circuit switched bearer to transmit early session media to a first user equipment. The existing circuit switched bearer is established under control of the media gateway control device for a session between the first user equipment and a third user equipment. The SCC AS receives an off-hook signal from the second user equipment, and sends the regular session media information to the media gateway control device.
Abstract:
A method for transmitting machine type communication (MTC) downlink data. The method includes acquiring, by a user equipment (UE), downlink transmission parameters, where the downlink transmission parameters include a quantity of resource blocks in downlink transmission bandwidth that is configured by a base station for the UE, an antenna port used by the base station for sending the MTC downlink data, and at least one of the following a cell-specific frequency shift value or a cyclic prefix (CP) type, setting, by the UE, a local oscillator frequency of a receiver according to the downlink transmission parameters; and receiving, by the UE, the MTC downlink data sent by the base station, where a subcarrier located in a subcarrier reservation location does not carry any data signal or reference signal, and the subcarrier reservation location is determined in the downlink transmission bandwidth by the base station according to the downlink transmission parameters.
Abstract:
Embodiments of the present invention provide a method and a device for location management of a group-based machine type communication MTC device. The method includes: receiving a location update message sent by a mobility management network element, where the location update message includes a device identity and/or a group identity of a first MTC device; acquiring the group identity of the first MTC device according to the location update message, and updating subscription data of all MTC devices in a group corresponding to the group identity; and sending subscription data of the group to the mobility management network element, where the group subscription data includes the group identity and/or a device identity list of all the MTC devices in the group. An embodiment of the present invention further provides a corresponding device.
Abstract:
The present invention discloses a method for triggering communication between a group of MTC devices and an MTC server, and an MTC device. The method includes: receiving an MTC request message sent by a machine type communications MTC server, where the MTC request message carries a group ID of the group of MTC devices and a communication notification message for the group of MTC devices; obtaining area information of the group of MTC devices; and sending the area information, the group ID of the group of MTC devices, and the communication notification message for the group of MTC devices to a cell broadcast center CBC, so that the CBC sends a broadcast message to a device in an area, where the broadcast message includes the group ID of the group of MTC devices and the communication notification message for the group of MTC devices.
Abstract:
A data transmission method, apparatus, and system are provided that relate to the communications field and that reduce core network bandwidth resources occupied by data transmission. The method includes receiving, by a first base station, a request message sent by a first device, where the request message carries identification information of requested data and identification information of the first device, and the first device includes a user equipment or a second base station; retrieving, by the first base station, in stored data according to the identification information of the requested data; and when matched data is retrieved, sending, by the first base station, the matched data to the first device according to the identification information of the first device, where the matched data refers to data that matches the identification information of the requested data.
Abstract:
A method and an apparatus for resource management, and a low-bandwidth user equipment. The method for resource management includes: determining, according to a system downlink transmission bandwidth or according to a system downlink transmission bandwidth and a maximum downlink transmission bandwidth of a low-bandwidth user equipment, a downlink transmission resource configured by a cell for the low-bandwidth user equipment. The method and apparatus for resource management proposed in the present invention are intended to solve a problem that a low-bandwidth user equipment accesses a broadband system, and enable, through resource management, a low-bandwidth user equipment and a common user equipment to coexist on a same frequency band without causing a waste of a dedicated frequency band resource.
