Abstract: A method for assigning to a terminal device (UE) a service server (SS) carried out by an IS, by any of the SSs, and by the UDB in a cooperative/corresponding manner. A “first reallocation (IS/SS/UDB) procedure” and a “second reallocation (IS/SS/UDB) procedure” are correspondingly performed within the IS, the SS and the UDB. The first reallocation procedure allows, via IS/SS/UDB processing and interactions, storing by the UDB, in relationship with at least one of the user identifiers of a UE, a mark indicating that the UE has been assigned to a replacement SS to substitute another SS that has failed. The second reallocation procedure allows, also via IS/SS/UDB processing and interactions, utilization of the mark to trigger a new SS reallocation of the UE to a SS when the UE sends a subsequent registration message.

The processor detects one or more delays in the transmission of the low latency data. The processor issues a flow control command to pause a port from sending frames to the Ethernet for a given amount of time in response to detecting the one or more delays.

Abstract: Techniques for mobile communication in an unlicensed frequency band are discussed. A network device (e.g., an evolved NodeB, or other cell network device) can generate a listen before talk (LBT) protocol in order to determine whether an unlicensed carrier of a secondary cell device is idle or busy. The LBT protocol can be generated as a one shot LBT within a two symbol duration of a potential downlink (DL) transmission burst, or multiple times within the two symbol duration. In response to an idle state detection, a discovery reference signal (DRS) can be transmitted. In response to the LBT protocol and the DRS transmission being misaligned, a reservation signal can be generated to reserve the unlicensed carrier for the DL transmission.
