Abstract: The present disclosure discloses methods, systems and devices for supporting local breakout in a small cell architecture. An MME sends information of a local breakout bearer for a UE to a MeNB, and the MeNB determines a local home network to which the local breakout bearer belongs according to the received information. When the MeNB is to switch the local breakout bearer between different eNBs, the MeNB selects an eNB in the local home network to which the local breakout bearer belongs as a target eNB. By the present disclosure, the continuity of local breakout traffic may be ensured when a User Equipment (UE) moves in a small cell scenario, thereby avoiding data loss and improving user experiences. Further, a local breakout bearer may be released timely and reasonably, thereby saving system resources.

Abstract: The present disclosure provides a method for obtaining a UE counting result. The method includes: establishing, by the UE, a RRC connection; sending a UE counting response via the RRC connection; or, sending, by the UE, a RRC establishing message, and configuring a reason of establishing the RRC as MBMS UE counting. The present disclosure also provides a method for obtaining a UE counting result, a method and apparatus for suspending data transmission. By using the present disclosure, when the UE needs to receive the GCSE service, the MCE may obtain a correct counting result and not make wrong decision no matter whether the UE is in the RRC connected mode or in the idle mode. Therefore, the UE does not need to establish the point-to-point channel, and interruption of the data transmission and unnecessary power consumption are avoided.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a method of de-activating a local internet protocol access (LIPA) bearer supporting local breakout in a dual-connectivity architecture. When a master eNodeB (MeNB) determines to change a secondary eNodeB (SeNB) serving a user equipment (UE) or hand the UE over from the MeNB to an eNB, the MeNB may trigger a LIPA bearer de-activation process, and then trigger the process of change the SeNB serving the UE or hand the UE over from the MeNB to the eNB. Various examples also provide another method and an apparatus for de-activating a LIPA bearer, for bearer switch, for establishing a LIPA bearer. The methods and apparatus can establish, switch and correctly release local breakout bearer in a dual-connectivity architecture, so as to reduce the load of a core network of an operator.

Abstract: Disclosed is a method for access of a user equipment (UE) in a communication system, which 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 network node receiving 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 sending 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.
