Abstract: In a method for accessing a legacy wireless network, a radio access network (RAN) node in the legacy wireless network receives an access message sent by a User Equipment (UE) attempting to access the legacy wireless network. The access message includes mobility management entity (MME) information identifying an MME accessed by the UE in an evolved network. The MME information is added by the UE from a temporary identity (ID) allocated by the MME to a first P-Temporary Mobile Station Identity (P-TMSI) in the access message. The RAN node selects a corresponding Serving GPRS Support Node (SGSN) in the legacy wireless network for the UE according to the first P-TMSI in the access message.

Abstract: Embodiments of the present invention provide a method for controlling packet access, a network side device, a terminal device and a communication system. The method includes: generating an access trigger message, where the access trigger message carries a temporary mobile group identity TMGI allocated to a user equipment UE; and sending the access trigger message to packet trigger an access operation of the UE for the TMGI. In the embodiments of the present invention, the group identity TMGI already existing in an MBMS can be used as the group identity of packet triggering UE access, and the access trigger message carrying the TMGI can be correspondingly generated and sent so as to trigger an access operation of the UE belonging to the TMGI, thereby implementing the function of the packet triggering user access.

Abstract: Embodiments of the present invention disclose a machine to machine service management device, a network device, a method processing service and system. An MSMC is added between an MTC server and a 3GPP network to perform service processing, and during the service processing, after a trigger receiving unit in the MSMC receives a triggering request message, a session establishing unit establishes a corresponding service session according to information of a requested group service, and a request sending and establishing unit sends a service request to a BM/SC device to establish a corresponding service session and establish a link with an MTC device. Therefore, security of a network system of the MTC application is improved.
