Abstract: The present invention provides a method for processing abnormalities between non-adjacent nodes. which is applied to network element nodes supporting a GPRS Tunneling Protocol (GTP). The GTP node sends a network element-level node abnormality message to other adjacent GTP nodes once the abnormality of an adjacent GTP node is detected. The message comprises information about the abnormal GTP node. The method of the present invention enables the non-adjacent GTP nodes to obtain each other's abnormality therebetween and perform relative processing by introducing the network element-level node abnormality message, thus solves the problem when the GTP is used in the 3GPP system that the resources cannot be recycled in time because of each other's unknown recovery between the non-adjacent nodes, or the problem of a message storm that may caused by the user-level message notification through the intermediate node.

Abstract: A method for processing bearer reestablishment failure is disclosed in the present invention for preventing a SGW from doing error processing due to the bearer reestablishment failure in a SAE network. The method comprises the following steps: a mobility management entity (MME) sending a notification message to a service gateway (SGW) after reestablishment of a bearer, the notification message carrying effectiveness parameters indicating the effectiveness state of the bearer, and the SGW storing the effectiveness parameters; the SGW not delivering data packets if the effectiveness state of the bearer is failure when the SGW is to deliver data packets.

Abstract: A method and device for deploying evolved nodes are provided in the present invention, and the method comprises: a MME acquires a connection establishment request from an e Node B, wherein the connection establishment request carries a global identifier of the e Node B; the MME acquires the global identifier, and searches for corresponding e Node B information according to the global identifier, and if the corresponding e Node B information cannot be found, the MME deploys the e Node B. With the present invention, the MME in a mobile communication packet domain evolved system can directly deploy e Node B, which increases the number of e Node B in the mobile communication packet domain evolved system, and satisfies the demand of the mobile communication packet domain evolved system on e Node B.

Abstract: The present invention provides a method and a device for deploying tracking areas. The method comprises: the mobile management entity MME acquires the connection establishment request from the Evolved Node B (e Node B), wherein, the connection establishment request carries one or more tracking area identities TAIs corresponding to the one or more tracking areas belonging to the e Node B; the MME acquires the one or more TAIs from the connection establishment request and locally searches the one or more TAIs; if the one or more TAIs are not found, the MME deploys the one or more tracking areas corresponding to the one or more TAIs. By the present invention, the MME of the mobile communication packet domain evolution system directly deploys the tracking areas, which increases the number of the tracking areas of the mobile communication packet domain evolution system, and satisfies the demand to the tracking areas of the mobile communication packet domain evolution system.
