Abstract: An electronic device is provided and includes a backplane assembly, a detachable assembly and a locking assembly. The detachable assembly is detachably assembled with the backplane assembly. A slot is formed on the detachable assembly. The locking assembly is disposed between the backplane assembly and the detachable assembly for locking the detachable assembly on the backplane assembly. The locking assembly includes a latch component pivotally disposed on the backplane assembly. An end of the latch component is configured to stretch into the detachable assembly through the slot. The end of the latch component engages with the slot for restraining the detachable assembly from being detached from the backplane assembly when the latch component is located at a locking position. Besides, a related backplane assembly kit and a related detachable assembly kit are also provided.

Abstract: A rail mounting backplane kit is provided and including a backplane assembly, a first mating structure and a second cooperating structure. The first mating structure is for cooperating with a first cooperating structure of a first cooperating backplane kit for allowing or restraining assembly of the backplane assembly and a first cooperating backplane assembly of the first cooperating backplane kit, and the first mating structure includes a plurality of first mating features, which can selectively be protruding, flat or recessed mating features. The second cooperating structure is for cooperating with a second mating structure of a second cooperating backplane kit for allowing or restraining assembly of the backplane assembly and a second cooperating backplane assembly of the second cooperating backplane kit, and the second cooperating structure includes a plurality of second cooperating features, which can selectively be protruding, flat, or recessed cooperating features.

Abstract: A rail mounting backplane assembly kit is provided and includes a backplane assembly, an engaging hook and a slot structure. The backplane assembly can be mounted on a rail and detachably assembled with a first cooperating backplane assembly or a second cooperating backplane assembly. The engaging hook is movably disposed on the backplane assembly. The engaging hook includes an operating portion, an engaging portion and a connecting portion connected between the operating portion and the engaging portion and received inside the backplane assembly. The operating portion and the engaging portion are exposed out of the backplane assembly. The engaging portion is for engaging with a cooperating slot structure on the first cooperating backplane assembly. The slot structure is formed on the backplane assembly and for engaging with a cooperating engaging hook on the second cooperating backplane assembly. Besides, a related rail mounting electronic device is also provided.

Abstract: An electrical connector assembly including a first connector and a second connector to be mated with each other is provided. The first connector includes a first body, and at least one first terminal and multiple second terminals disposed therein. The second terminals are symmetrically arranged at opposite sides of the first terminal. The second connector includes a second body, at least one third terminal movably disposed in the second body, multiple fourth terminals disposed in the second body and symmetrically arranged at opposite sides of the third terminal, and a driving module electrically connected to at least one of the fourth terminals and structurally connected to the third terminal. In the mating process of the first and second connector, the second terminals and the fourth terminals are electrically connected firstly, to trigger the driving module to move the third terminal to be structurally and electrically connected to the first terminal.

Abstract: In a carrier assignment procedure, a mobile station and its serving base station exchange and negotiate carrier deployment and multi-carrier capability information, and make a well-informed carrier assignment decision based on the negotiation result. The carrier assignment procedure ensures that the assigned secondary carriers are not only supported by both the serving BS and the MS, but are also desirable under additional requirements and considerations. Furthermore, the carrier assignment decision may be updated based on additional considerations such as channel quality measurement and network load condition over the assigned carriers. Such updated assignment decision may be made by the base station in unsolicited manner, or based on a carrier re-assignment request from the mobile station.

Abstract: Carrier pre-assignment is applied in multi-carrier handover operation to mitigate the impact to the user experience during handover and to achieve various objectives of call admission control in wireless multi-carrier OFDM networks. With carrier pre-assignment, a mobile station communicates its multi-carrier information to a target base station. The target base station pre-assigns secondary carriers to fulfill the requirements of the mobile station. In a first embodiment, a break-before-entry (BBE) multi-carrier handover procedure with carrier pre-assignment is provided. In a second embodiment, an entry-before-break (EBB) multi-carrier handover procedures for both inter-FA and intra-FA with carrier pre-assignment are provided. The multi-carrier handover procedures with carrier pre-assignment may be applied to 2-to-2 or N-to-N carriers handover situation.
