In a radio communication system wherein radio frequencies for communicating with a radio terminal are different in radio base stations, a table in which positional information, information on the frequency used for transmission/reception to/from the terminal, and a decision condition in a handoff operation are stored as to each base station is prepared in a base station controller beforehand. When the positional information is received from the radio terminal, the base station controller selects the base station being a handoff candidate, on the basis of the positional information of the radio terminal, the positional information of each base station and the decision condition of the handoff operation with reference to the table, and it transmits a handoff request message which contains the information on the frequency of the base station being the handoff candidate, to the radio terminal through the base station communicating with the radio terminal.

The embodiment of the invention provides a method and a device for providing a differentiated service for UE. The method mainly comprises the following steps of: obtaining the RAB (Radio Access Bearer) priority of the UE according to UE type information, user grade information and service type information; and providing a service for the UE according to the RAB priority. By utilizing the embodiment of the invention, on the basis of the RAB priority of the UE, the embodiment of the invention can allocate resources, such as bandwidth and the like to the UE, provide the differentiated service for the UE, obtain the comprehensive priority control strategy of the UE and achieve the optimal operation effect of an operator.

The invention discloses a method and a device for processing update failure of a double-connection path. The method and the device could be used for transmitting and processing data after a path update is failed in the adding process of an auxiliary evolution type node in a long-term evolved communication system double-connection framework. The method comprises the steps as follows: 1) obtaining an update failure type of the path; judging whether a partial bearer path is updated successfully or a whole bearer path is updated successfully according to radio access bearer modification confirming information transmitted by a mobile management entity to a main evolution type node B; 2) processing according to a preset strategy. On the basis of prior art, the method and the device of the invention could obtain the preset path update failure processing strategy according to the update failure type of the path and process according to the preset strategy so as to reduce packet loss, ensure service continuity, and improve user experience.
