摘要： A method, a mobility management unit and a gateway unit for restricting access and communication of a machine type communication (MTC) device are provided by the present invention. The method includes: a mobility management unit judging whether an access request or a service request of the MTC device is currently in a permission period according to the permission period of the MTC device; when the access request or the service request is not in the permission period, rejecting the access request or service request of the MTC device and notifying the MTC device of the rejection cause and/or the permission period at a meantime. The present invention can ensure that the MTC device only communicates in the permission period, and the MTC device is restricted to access the network or communicate in the non-permission period according to the requirement of the operator.

摘要： The present disclosure discloses a method for paging an emergency service user. When a mobility management unit is configured to support the paging optimization in a core network, the mobility management unit does not perform paging optimization when a UE has an emergency bearer service. That is to say, a paging message is sent to all base stations (including the CSG-mode home base station that does not authorize the UE) in the paging tracking list registered by the UE. A core network gateway can notify the mobility management unit of whether the UE has an emergency bearer service. Alternatively, the mobility management unit configured to use the paging optimization, after learning that the service data is to be sent to the UE, checks the current service type of the UE to determine whether the UE has an emergency bearer service. Accordingly, the present disclosure further discloses a system for paging an emergency service user. The present disclosure solves the problem that the mobility management unit and home base station gateway using the paging optimization cannot page the UE which uses the emergency service, so as to increase the success rate of establishing communications and improve the user experience.

摘要翻译： 本公开公开了一种用于寻呼紧急服务用户的方法。 当移动性管理单元被配置为支持核心网络中的寻呼优化时，当UE具有紧急承载服务时，移动性管理单元不执行寻呼优化。 也就是说，在由UE登记的寻呼跟踪列表中，向所有基站（包括不授权UE的CSG模式家庭基站）发送寻呼消息。 核心网关可以通知移动性管理单元UE是否具有紧急承载业务。 或者，移动性管理单元被配置为在学习到要向UE发送业务数据之后使用寻呼优化来检查UE的当前业务类型，以确定UE是否具有紧急承载业务。 因此，本公开进一步公开了一种用于寻呼紧急服务用户的系统。 本公开解决了使用寻呼优化的移动性管理单元和家庭基站网关不能寻呼使用紧急服务的UE，从而提高建立通信的成功率并提高用户体验的问题。

摘要： A method and circuit for controlling a resonant DC/DC converter which adjusts an output voltage by changing a turn-on frequency of input switch devices of a resonant circuit of the converter. The method extends the range of the output voltage of the resonant circuit by adjusting the duty ratio of the switch devices based on the feedback signal of the load circuit. The method and circuit uses two modes to control resonance of the DC/DC converter-frequency modulation and frequency modulation plus pulse width modulation. Frequency modulation is used when the operating frequency of the power supply is low. Frequency modulation plus pulse width modulation is used when the operating frequency of the power supply is too high.

摘要： A hardware overvoltage disconnecting circuit wherein a DC power supply module is disconnected from a power network when the AC power network is in the state of overvoltage. The circuit includes a disconnecting relay and a voltage detection circuit. The disconnecting relay is connected in series between an AC power network and a power factor correction circuit of a power supply module. A first sampling terminal of the voltage detection circuit samples the voltage of the AC power network between the AC power network and the disconnecting relay, and an output of the voltage detection circuit is connected to a control terminal of the disconnecting relay. When the AC power network is in the state of overvoltage, the disconnecting relay is disconnected and the power supply module is disconnected from the AC power network. When the voltage of the AC power network is normal, the disconnecting relay is connected.

摘要： Wireless communication in a wireless system using a multiple user transmission opportunity is provided. Data blocks at a wireless station are transmitted to multiple wireless receivers over a shared wireless communication medium. The data blocks are organized in order of transmission priority based on access categories. Contention for access to the communication medium during a transmission opportunity period is based on a backoff timer of each access category and the transmission priority. Upon successful contention for a transmission opportunity period, during the transmission opportunity period, a data block of a primary access category is wirelessly transmitted from the wireless station to one or more primary destination wireless receivers. Simultaneously, a data block of a secondary access category is wirelessly transmitted from the wireless station to one or more secondary destination wireless receivers.
