Definitions

• FIG. 18 shows a flowchart illustrating a method in accordance with various aspects of the present disclosure.
• FIG. 19 shows a flowchart illustrating a method in accordance with various aspects of the present disclosure.
• a network may also employ mobility procedures that support low latency (e.g. , SIPFULL) operations.
• SIPFULL low latency
• the network, or entities of the network e.g. , RAN
• Such mobility procedures may include various methods of utilizing and allocating IP addresses by different entities of the system.
• FIG. 1 illustrates an example of a wireless communications system 100 in accordance with various aspects of the present disclosure.
• the system 100 includes base stations 105, UEs 115, and a core network 130.
• the core network 130 may provide user authentication, access authorization, tracking, IP connectivity, and other access, routing, or mobility functions.
• the base stations 105 interface with the core network 130 through backhaul links 132 (e.g., SI, etc.).
• two UEs 115 may both be within the system 100, and data may be routed between them without the necessity of first navigating the core network.
• two UEs 115 connected to a common base station 105 may have traffic between them routed within the base station 105 or LGW.
• the latency may be reduced to a value equivalent to two (2) times the TTI plus the HARQ RTT plus the time for communications between the base station 105 and the LGW.
• the delay associated with backhaul 132 may be avoided. This is also discussed more fully below, with reference to FIG. 2A-2C.
• the handover management module 1104-a may include a handover identification module 1240, a service continuity module 1245, a handover request transmission module
• FIG. 17 shows a flowchart illustrating a method 1700 for selected IP flow ultra low latency in accordance with various aspects of the present disclosure.
• the operations of method 1700 may be implemented by a UE or its components as described with reference to FIGs. 1-13.
• the operations of method 1700 may be performed by the communication management module 610 as described with reference to FIGs. 6-9.
• a UE may execute a set of codes to control the functional elements of the UE to perform the functions described below. Additionally or alternatively, the UE may perform aspects the functions described below using special-purpose hardware.
• the UE may route packets in accordance with the authorization signal via a local gateway (LGW) based at least in part on the authorization signal as described above with reference to FIGs. 2-5.
