A mobile communications network is arranged to establish one or more preconfigured shared logical communications bearers 204 between core network infrastructure equipment 205 and radio network base stations 203. Each of the communications bearers 204 is provided to communicate data to or from one or more of the base stations 203 for at least one mobile communications device in accordance with predetermined operating parameters for providing a predefined quality of service. The mobile communications network is also arranged to establish one or more preconfigured shared radio bearers 201 between the mobile communications device and the one or more base stations 203 for communicating the data to or from the mobile communications device from or to the base stations 203 in accordance with predetermined operating parameters for providing the predefined quality of service. The shared radio bearers 201 are allocated the predefined operating parameters required before the mobile communications device has data to be communicated via the shared communications bearers 204. Hence, transmission of relatively low quantities of simple machine type communication (MTC) or machine to machine (M2M) data may be efficiently supported over UMTS and LTE networks.

The invention provides a method for mounting steel members or prefabricated members of a roof or floor in place and equipment for realizing in-place mounting of the steel members or the prefabricated members of the roof or floor. In the method, the steel members or the prefabricated members (members for short) stacked on the roof or floor are mounted at a position in place; the equipment comprises a gallows frame, a front trolley and a rear trolley, wherein the gallows frame comprises two upright posts, a cross beam and at least two hanging pulleys; the two upright posts are supported against the two ends of the cross beam respectively; the hanging pulleys are hung on the cross beam; the front trolley comprises vehicle wheels, a vehicle body, a movable supporting surface and a roller; the vehicle body is arranged on the vehicle wheels; the movable supporting surface and the roller are arranged on the vehicle body for supporting the members to be mounted; the movable supporting surface is connected with the vehicle body through a lifting mechanism; the roller and the movable supporting surface are flush when positioned at the high position; the rear trolley comprises vehicle wheels, a vehicle body and a movable supporting surface; and the movable supporting surface is connected with the vehicle body through a lifting mechanism. By using some simple machines, the members are stably mounted at the position in place to save time and labor.

Charging handles having a mechanical advantage separator for separating an end of the charging handle from a portion of a firearm are disclosed. Specifically, charging handles having a simple machine, such as a lever, are disclosed. Advantageously, the simple machine can multiply the force applied by a user on the charging handle. Additionally, in at least some instances, the simple machine will actuate a charging handle latch so as to disengage the charging handle latch from a receiver of the firearm.
