Embodiment Construction

[0039] Below, the present invention will be described in detail in combination with specific embodiments.

[0040] figure 1 The flow chart of the associated data management method is given, and the specific implementation steps of the associated data management method are as follows:

[0041] (1) Initialization parameters: Construct uplink associated data table and downlink associated data table to record signaling plane data. The length of the associated data cache queue is l; the maximum capacity of the uplink associated data table is m (the unit is the number of entries); the maximum capacity of the downlink associated data table is n (the unit is the number of entries); the associated data counter N is set to 0; the associated data The ratio of the maximum capacity of the counter to the associated data is r (that is, N / m or N / n); the timeout period t (in seconds) of the associated data; the length o of the timeout queue of the associated data;

[0042] (2) The management...

Abstract

The invention discloses a method for maintaining associated data of a signaling plane and a user plane in a 4G network environment. The method comprises the following steps of 1) setting an uplink associated data table and a downlink associated data table,2) judging the operation type of the associated data corresponding to the received s11 data packet, and if the operation is newly added or updated, turning to the step 3),3) judging a data type of the associated data, and if the data type is an F-TEID and an eNodeB tunnel IP address, turning to the step 4),if the IP address is the F-TEID andthe PGW tunnel IP address, turning to the step 5),4) searching signaling plane data matched with the F-TEID of the current associated data and the IP address of the eNodeB tunnel in the uplink associated data table, turning to the step 5), orotherwise, executing the step 6),5) finding downlink data corresponding to the s11 data packet from a downlink associated data table according to the signaling plane data of the s11 data packet and updating the downlink data, and 6) newly establishing a signaling associated storage node and inserting uplink associated data into an uplink associated data table.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for maintaining associated data of a signaling plane and a user plane under a 4G network environment. Background technique [0002] With the advancement of technology, mobile communication has experienced 1G, 2G, and 3G eras, and is currently in the 4G era. Compared with 2G and 3G. The 4G core network no longer has the circuit domain CS (Circuit Switch, circuit switched) part, only has the packet domain EPC (Evolved Packet Core, evolved packet core), in the EPC, MME (Mobility Management Entity, mobility management entity) and SGW ( Serving Gateway, Serving Gateway) realizes SGSN (Serving GPRS Support Node, Serving GPRS (General Packet Radio Service, is the abbreviation of general packet radio service technology) support node) function, PGW realizes GGSN (Gateway GPRS Support Node, gateway GPRS Support node) function, but the 4G core network EPC realiz...
