Abstract: The present disclosure provides a method for access of a user equipment (UE) in a communication system. The communication system includes the UE, a base station, and a network node. The base station carries out radio link control (RLC) layer and media access control (MAC) layer functions. The network node carries out packet data convergence protocol (PDCP) layer, radio resource control (RRC) layer, and non-access (NAS) layer functions. The method includes the following steps. The network node receives a non-access stratum identifier of the UE or a random number generated by the UE sent from the UE through a RRC message, and the network node sends the received non-access stratum identifier or the random number to the base station, for the base station to set a UE collision dismiss identifier. Using the present disclosure, different users accessing to a network can be supported. The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.

Abstract: Various examples provide a method of caching service data in LTE networks. A base station parses a data request received from a UE to obtain an identification of requested contents, judges whether the requested contents are cached in the base station, sends the contents to the UE in response to a determination that the requested contents are cached in the base station. In response to a determination that the requested contents are not cached in the base station, the base station judges whether the requested contents are cached in an adjacent base station, and obtains the contents from the adjacent base station and returns the contents to the UE in response to a determination that the requested contents are cached in the adjacent base station. In response to a determination that the requested contents are not cached in adjacent base stations, the base station forwards the data request to an SGW, and returns contents obtained from the SGW to the UE. Various examples also provide another method and apparatus of caching service data in an LTE network. According to the examples, data requests of UEs are not necessarily always forwarded to a business server. Instead, requested data is first sought from a cache (in a base station and/or an SGW) which is the closest to the user to reduce transmission load of the LTE network, reduce the time delay in obtaining service data by users, and improve the quality of experience of users.
