Description

Migration implementation method, reporting failure method, communication system and relevant device

Technical field

The present invention relates to communication field, relate in particular to a kind of migration implementation method, reporting failure method, communication system and relevant device.

Background technology

When the position of subscriber equipment changes, may move by trigger position, service wireless network controller (SRNC then, Serving Radio Network Controller) when perceiving the change in location of subscriber equipment, then can initiate migration request Relocation Required to core net, the floating radio network controller (DRNC, Drift Radio Network Controller) that indication need migrate in this migration request.

Core net is received after the migration request of SRNC transmission, in conjunction with the content in the migration request, finds the sign of the DRNC that need migrate to, assembles migration request message (Relocation Request), and gives DRNC with this migration request message.

DRNC sets up signaling plane and user's face between DRNC side and the core net after receiving the migration request message that core net sends, and replys the migration response to core net afterwards.Core net will be moved response and will be handed down to SRNC, and last core net issues the request of release, and SRNC is connected release with signaling between the core net, the migration between so far finishing from SRNC to DRNC.

Third generation partner program (3GPP, 3rd Generation Partnership Project) agreement develops into after Release 8 versions, introduced the enhancement mode migration, this enhancement mode migration regulation, if subscriber equipment belongs to a core net node in the core net of SRNC access and the core net that inserts at DRNC, then can be by the Signalling exchange between the IUR interface to realize migration, this IUR interface is meant the communication interface between the different RNC.

In the enhancement mode migration, SRNC can directly send enhancement mode migration request Enhanced Relocation Request to DRNC by the IUR interface, and DRNC also can be by the IUR interface directly to SRNC feedback-enhanced migration response Enhanced Relocation Response.

In the present embodiment, when the change of UE occurrence positions causes the needs migration, after 3GPP Release 8 versions, can adopt the enhancement mode migration, then SRNC can send the enhancement mode migration request to DRNC.

Need to prove that the condition that triggers migration is not limited to the change of UE occurrence positions, in actual applications, can also be other trigger condition, the load of for example current SRNC that serves for UE is high excessively, and concrete trigger condition does not limit herein.

The condition of corresponding different triggering migrations, the type of concrete enhancement mode migration does not limit in the present embodiment yet, for example, can be " resources optimization migration (resource optimization relocation) " in actual applications, or " reducing service node load (reduce load in serving cell) migration " etc., particular type does not limit herein.

Carry alternative enciphered message and/or alternative integrity protection information in the enhancement mode migration request that SRNC sends, this alternative enciphered message and/or alternative integrity protection information are preset among the SRNC by core net.

102, DRNC chooses application encipher information, and/or application integrity protection information;

In the present embodiment; DRNC can get access to alternative enciphered message and/or alternative integrity protection information from the enhancement mode migration request that SRNC sends, then DRNC can from these alternate information, choose satisfy prerequisite information as application message (comprising application encipher information and/or application integrity protection information).

103, DRNC sends the enhancement mode migration that comprises application encipher information and/or application integrity protection information to core net and finishes request.

In the present embodiment; after DRNC has chosen application encipher information and/or application integrity protection information; then can be when request is finished in the migration of core net transmission enhancement mode; carry these application messages, then can encrypt and/or integrity protection the data of transmission between core net and the DRNC.
