摘要： A method for switching of multi-carrier and device are provided. The method comprises: receiving a message sent from a source RAN node corresponding to a first link and comprising information of a second link; according to the information of the second link, establishing a connection between a target RAN node corresponding to the first link and an RAN node corresponding to the second link, so as to perform data transmission. The first link is a link in a first Radio Access Technology (RAT) network, and the second link is a link in a second RAT network. Embodiments of the present invention can ensure the continuity of the throughput of data transmission during switching under aggregation of multiple RAT carriers.

摘要： The disclosure provides a method for updating an air interface key, a core network node and user equipment. The update method comprises: a core network node receives a relocation indication message, wherein the relocation indication message is configured to indicate that the User Equipment (UE) is about to relocate to a target Radio Network Controller (RNC) from a source RNC (Step S602); the core network node uses the key parameter to calculate a next hop enhanced key (Step S604); and then the core network node sends the next hop enhanced key to the target RNC (Step S606). Through the disclosure, the forward security of the user is guaranteed, and thus the communication security of the radio access system is improved.

摘要： A method and system for acquiring continuous packet connectivity technology support capability information. The method comprises the following steps: Step 102, sending a radio link establishing request message or a radio link adding request message to a drift radio network controller when it is monitored that a UE needs to establish or add a radio link with a cell dominated by the drift radio network controller, by means of a serving radio network controller; Step 104, adding a continuous packet connectivity technology support capability information of an adjacent cell into a radio link establishing response message or a radio link adding response message after the radio link establishing request message or the radio link adding request message is received, and returning the radio link establishing response message or the radio link adding response message to the serving radio network controller, by means of the drift radio network controller; Step 106, acquiring the continuous packet connectivity technology support capability information of the adjacent cell from the radio link establishing response message or the radio link adding response message, after the radio link establishing response message or the radio link adding response message is received, by means of the serving radio network controller.

摘要： Cell update while in a Cell_FACH state After selecting a target cell, system information is read from the target cell including high speed downlink shared channel (HS-DSCH) common system information. A radio network temporary identity (RNTI) received in a source cell is cleared and a variable HS_DSCH_RECEPTION is set to TRUE. An HS-DSCH medium access control (MAC-hs) entity is configured based on the HS-DSCH common system information. High speed downlink packet access (HSDPA) transmission is then received in the target cell. A CELL UPDATE message is sent to notify of a cell change. The HSDPA transmission may be received using a common H-RNTI broadcast in the system information, a reserved H-RNTI as requested in a CELL UPDATE message, or a temporary identity which is a subset of a U-RNTI.

摘要： Transferring a mobile node from one ASN-GVV ( anchor access sen ice network gateway ) to another ASN-GW is referred to as a hand-over. To facilitate transfer of data for the hand-over, a GRE (generic routing encapsulation) tunnel is established between the two GWs Traffic through the GRE tunnel arriving at a line card of an ASN-GW is redirected from the arrival line card to the one line card that contains information for the mobile node The redirection is based on traversal of one or more tables, on the line cards These tables are indexed according to GRF, keys corresponding to the mobile nodes Therefore, the appropriate line card for the traffic can be identified quickly and efficiently using a distributed forwarding aiding plane with minimal provisioning overhead, resulting in lower latency during the hand-over

摘要： A roaming method for a mobile terminal in a wireless local area network is disclosed. In the method, a target access point (AP) device receives an access request for roaming from the mobile terminal, and a target access controller (AC) obtains mobility information of the mobile terminal in an original extended service set based on the access request, wherein the mobility information include information of an AP device, an AC and a mobile agent server associated with the mobile terminal. Then the target AC determines whether the roaming for the mobile terminal is an inter-IP subnet roaming or an intra-IP subnet roaming based on the obtained mobility information. The target AC performs mobile IP based handover when the roaming is determined as the inter-IP subnet roaming and performs Inter Access Point Protocol based handover when the roaming is determined as the intra-IP subnet roaming.
