The embodiments herein relate to a method performed by a mobility node for handling a UE which has moved from an old to a new location. The mobility node retrieves UE context from a database. The mobility node determines whether there is a change of mobility node and first gateway at the new location. When there is a change of the first gateway, the mobility node initiates setup of a tunnel between a second gateway and a new first gateway. When there is a change of the mobility node, the mobility node provides a subscriber server with UE context for a new mobility node at the new location. The mobility node transmits updated UE context to the database.

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. Embodiments herein provide a method for performing a routing ID (RID) update in user equipment (UE) in a wireless communication network.

A method and device for accessing and obtaining user equipment (UE) context and UE identity are provided. The method for access includes: when a UE accesses a System Architecture Evolution (SAE) network, judging, by a network node, whether a Globally Unique Mobility Management Entity Identifier (GUMMEI) carried by the UE or a Mobility Management Entity Group Identity (MMEGI) in the GUMMEI is allocated or mapped by the SAE network; if the GUMMEI or MMEGI is allocated by the SAE network, selecting, by the network node, a Mobility Management Entity (MME) according to the GUMMEIA network device includes an identity attribute obtaining module and a network resource node allocation module. Therefore, the access of the UE is achieved.

A non-MNO PSP network maintains a table that maps external subscriber identifiers of UEs to intermediate subscriber identifiers of the UEs on an interface between the non-MNO PSP network and NHN(s). The non-MNO PSP network obtains an SCEF-related message including either an external subscriber identifier or an intermediate subscriber identifier for the UE. Using the table, the non-MNO PSP network forwards the SCEF-message to a serving NHN or to an external application. In another embodiment, an NHN maintains a table that maps internal identifiers of UEs within the NHN to intermediate subscriber identifiers that identify the UEs on an interface between the NHN and non-MNO PSP(s). The NHN obtains an SCEF-related message that includes an intermediate subscriber identifier or an internal identifier for the UE. Using the table, the NHN either processes the SCEF-related message within the NHN, or forwards the SCEF-related message to a non-MNO PSP outside the NHN.

Methods and apparatuses for mobility between different communication systems are disclosed. According to an embodiment, a session management function (SMF) sends, to a service provider, a request for registering information related to the SMF to the service provider. The information related to the SMF comprises information indicating or derived from an Internet protocol (IP) address of a packet data network (PDN) gateway (PGW) control plane (PGW-C) that is combined together with the SMF. The SMF receives, from the service provider, a response to the request.
