A cell and a method and a system for bandwidth management of a backhaul network of the cell, adapted for arranging a routing path of a bearer established between a user equipment and a serving gateway through the cell in the backhaul network, are provided. In the method, the cell connects the user equipment to establish the bearer between the user equipment and the serving gateway or change an established bearer. The cell sets a packet label on the data packets of the bearer and transmits the packet label and bandwidth management information of the bearer to a controller of the backhaul network for the controller to arrange the routing path of the data packets using the packet label in the backhaul network according to the bandwidth management information.

A base station and a method that reduce abnormal cell re-selection behaviors. The base station includes: a detection module having a pattern information detector that provides pattern information of an almost blank subframe, and a measurement configuration adjustor that provides a first parameter threshold for cell-selection and generates a second parameter threshold for cell-selection according to the pattern information; and a measurement configuration generating module having a measurement configuration schedule generator that generates a broadcasting schedule according to the pattern information, a system information broadcaster that transmits first schedule information to first user equipment when the first user equipment establishes connection to allow the first user equipment to receive the first parameter threshold according to the first schedule information and perform cell-selection, and a dedicated signal generator that generates a dedicated signal and transmits second schedule information to second user equipment when the second user equipment establishes connection.

The present invention provides a PoC system (push-to-talk over cellular system) and a method for distributing media data in PoC. The PoC system includes a plurality of clients, a controlling server and a first participating server. In the present invention, since a media receiving port is established in the first participating server which manages at least two clients at the same time, and when a media data is going to be distributed to the clients managed by the first participating server, the controlling server delivers the media data to the media receiving port only. In addition, a multicast addressing technology is further used in the first participating server, therefore, the path of delivering media data is changed and the efficiency of media data delivery during a communication is improved.

A method and system capable of providing mobility support for IPv4/IPv6 inter-networking to a mobile node is disclosed. The mobile node in the system has an address mapper, an IPv4 protocol stack and an IPv6 protocol stack in the network layer. When moving from IPv4 to IPv6 networks, the mobile node registered an IPv4 address receives router advertisement packets from an IPv6 router, so as to obtain a IPv6 care-of-address, and resolve the IPv6 care-of-address by an IPv4 care-of-address. The address mapper issues an IPv4 message to register the IPv4 care-of-address. When moving from IPv6 to IPv4 networks, the mobile node registered an IPv6 address receives agent advertisement messages from a foreign agent, so as to obtain an IPv4 care-of-address, resolve the IPv4 care-of-address by an IPv6 care-of-address. The address mapper issues an IPv6 message to register and update binding information by the IPv6 care-of-address.
