Abstract: The present disclosure provides a method and a device for implementing a proximity communication service. The method includes steps of: receiving a request for the proximity communication service from a UE; in accordance with the request for the proximity communication service from the UE, determining a proximity communication service identifier obtained when the UE subscribes for the proximity communication service; and in accordance with the proximity communication service identifier of the UE, implementing the proximity communication service. According to the present disclosure, it is able to prevent the situation where the proximity communication service cannot be implemented when a UE's 3GPP network layer identifier cannot be determined in accordance with a UE's application layer identifier, thereby to implement the proximity communication service of the UE.

Abstract: The present invention discloses a method and device for re-initiating EPS session management procedure. The application of technical solution proposed through embodiment of this invention can enable PGW to determine whether handover operation on MME side is completed through timing by timer and/or instruction message on MME side; if it is completed, re-initiate session management process of corresponding EPS system, thus enabling PGW to timely re-initiate EPS session management procedure, reducing the time for unnecessary waiting, and avoiding resource waste caused by repeated rejection of EPS session management procedure re-initiated when handover procedure is not completed, so as to improve reconnection efficiency of session management process of EPS system and reduce waste of communication resource.

Abstract: The present disclosure relates to the field of communication technology, and provides an information processing method, an information processing device, a computer-readable storage medium and an electronic device, so as to reduce signaling overhead. The information processing method includes: receiving a registration update request from a UE; determining whether the UE has entered or left an MICO mode; when the UE has left the MICO mode, sending a first message to an associated SMF, the first message being adopted to notify the associated SMF that the UE has left the MICO mode or the UE is reachable; and when the UE has entered the MICO mode, sending a second message to a target SMF, the second message being adopted to notify the target SMF that the UE has entered the MICO mode or the UE is unreachable.

Abstract: A dedicated bearer creation method, an MME, and a PDN gateway are provided. The dedicated bearer creation method includes: in a TAU procedure, when it is determined that a UE has moved from a 5G network to a 4G network based on identification information provided by the UE, keeping a control plane NAS connection after the TAU procedure; and when a create dedicated bearer request has been received from a PDN gateway, creating a dedicated bearer for the UE using the NAS connection. According to the present disclosure, it is able to create a radio bearer based on the practical need, and prevent the occurrence of a waste of air interface resources caused when the MME requests an eNB to create a user plane radio bearer in the TAU procedure, thereby to solve the problem in the related art where the waste of the air interface resources is caused by a dedicated bearer creation scheme.

Abstract: Disclosed are a session management method and apparatus, wherein same are applied to a mobile network. The method comprises: determining a registration mode of a terminal sending a session establishment request or an interoperation capability supported by a network side device; and when the registration mode is a single-registration mode or when the network side device supports the interoperation capability, determining the completion of the mapping of QoS parameters between different systems when a session connection is created for the terminal. The present invention solves the technical problems in the prior art that an SMF cannot determine whether QoS mapping needs to be performed when a terminal is establishing a session connection in a mobile network and that an unnecessary signalling process will be caused for a terminal with a dual-registration mode if the SMF always performs QoS mapping.
