A paging method, an Mobile Management Entity (MME) and a terminal are provided, which relate to the field of communication technology, to reduce signaling overheard of the terminal and prevent the transmission of downlink data from being delayed. The paging method includes steps of: receiving downlink data for a target terminal; and in the case that the target terminal is in an idle state, adopts an extended DRX period and is capable of receiving a paging message, initiating a paging request to the target terminal based on the downlink data.

A method and device for transmitting Internet Protocol (IP) data packet are disclosed by the present invention, the method comprising: an Access Point (AP) device obtains an IP data packet needing to be sent to an User Equipment (UE); said AP device use the type information of said IP data packet to determine the corresponding Data Radio Bearer (DBR) of said IP data packet; Said AP device sends said IP data packet to said UE through said DBR; in the embodiments of the present invention, when the AP device accesses the IP network locally or directly through the IP network, the Quality of Service (QoS) insurance of IP data packet in the air interface transmission is implemented, on the basis of the direct mapping between the type information and the data radio bearer.

Method and device for transmitting IP data packet

The present disclosure provides a mobile communication system, including: a local access server configured to achieve a multi-RATs coordination function, a local access function and distributed network control; a network control function including a communication control function for communication control and a policy control function for policy control; and a network controller configured to establish and configure a forwarding path.

Mobile communication system, local access server and network controller

A management method and apparatus for a Closed Subscriber Group (CSG) white list are provided in the present invention, which can avoid the case that causes the CSG white list of a User Equipment (UE) to include a new Operator CSG List (OCL) and an old Allowed CSG List (ACL). The method includes the following steps: a User Equipment (UE) receives an updated Operator CSG List (OCL) or an Allowed CSG List (ACL) from a network side; according to the updated OCL or ACL, UE generates the CSG white list. With the present invention, when UE performs cells selection or handover according to the CSG white list which is provided to a non-access stratum by an access stratum as a basis for access control, the selected CSG identifier can not be refused by the network, the user experience can not be reduced, and unnecessary network signaling overhead can not be increased.

Management method and apparatus for closed subscriber group white list

The present application relates to mobile communication technical field, and a method for optimizing activation/deactivation Idle State signaling Reduction (ISR) and a network side device are disclosed. The method includes: during a process of updating User Element (UE) area, a first network entity, when receiving a context request message transmitted from a second entity, determines to activate or deactivate ISR, according to a mobile-reachable timer or an implicit detach timer corresponding to said UE, or operation states of the mobile-reachable timer and the implicit detach timer; and the first network entity transmits the determination result to the second network entity, said second network entity determines to instruct the UE to activate or deactivate the ISR according to the received determination result. The application optimizes the existing procedure for the activating/deactivating of the ISR, enables the ISR processing at the network side and the UE side to be consistent in height, and thus avoiding unnecessary signaling expense.

Method and network-side device for optimizing activation/deactivation of ISR

The present invention discloses a method and device for processing paging message when Idle State Signalling Reduction (ISR) is active. The method includes the following step: a Mobility Management Entity (MME) determines that a Mobile Switching Center (MSC)/Visited Location Register (VLR) is a default MSC/VLR and the paging message is used for a Short Message Service (SMS), the MME does not send the paging message to a Serving General Packet Radio Service (GPRS) Support Node (SGSN). The present invention can reduce the unnecessary paging signalling in an Evolved Packet System (EPS) and the 2nd Generation (2G)/3rd Generation (3G), therefore avoiding the network resource waste occurred in the interface of the MME and the SGSN, in the air interface of a General Packet Radio Service/Enhanced Data Rate for Global System for Mobile communication Evolution Radio Access Network (GERAN)/Universal Terrestrial Radio Access Network (UTRAN), and in the MSC/VLR.

Method and device for processing paging message when idle state signalling reduction is active

A paging method and device are disclosed, and the technical solution includes: determining to page an user equipment (UE) by using international mobile subscriber identity (IMSI), and before the paging, judging whether tracking area identity list (TAI List) of the UE is stored, and if the judgment result is 'no', then paging the UE in the tracking area (TA) served by the base station connected with the local area. Adopting the technical solution enables to effectively resolve the problem of uncertainness of paging an UE in which TAs, wherein the problem exists in the existing technology, and happens when mobility management entity (MME) pages the UE by using IMSI during the process of network error recovery.

Paging method and device

An informing method and equipment for index parameter of access type/frequency of selection priority are provided. Said method includes that a Mobility Management Entity (MME) receives the voice capabilities and settings reported by User Equipment (UE) (); the MME generates a Radio access type/Frequency of Selection Priority (RFSP) index according to the subscribed RFSP index, the voice capabilities and settings reported by said UE, and the operator's configuration policies (); when the MME determines that said generated RFSP index is different from the RFSP index in use, it replaces the RFSP index in use with said generated RFSP index (); the MME informs the Radio Access Network (RAN) of said generated RFSP index (). The present invention overcomes the problem that the transmission of the new RFSP index in use can not be finished under the condition that the UE is in an idle state, the UE has no uplink data, and the MME does not receive the notification of the downlink data.
