A cooperative apparatus and a resource block allocation method thereof for use in a wireless network are provided. The wireless network comprises a plurality of femtocells. The cooperative apparatus groups the femtocells based on signal interferences between the femtocells. The femtocells with higher signal interferences are joined to the same femtocell group. The cooperative apparatus averagely allocates resource blocks to the femtocells in the same femtocell group, and randomly allocates resource blocks to different femtocell groups.

A base station and an attaching method thereof are provided. A relay network system comprises the base station, a relay station and a core network. The base station is connected with the core network via a backhaul link. The base station comprises a processing unit and a transceiver. The processing unit is configured to setup a communication link procedure between the relay station and the core network corresponding to a link request from the relay station, and to create a mapping table for connecting the relay station and the core network. The transceiver is configured to forward network packets and control signals between the relay station and the core network based on the mapping table.

A wireless communication system is disclosed. The wireless communication system comprises a core network, a base station and a relay station. The relay station transmits a first message with a system resource information of the relay station to the base station. The base station generates a configuration pattern according to the system resource information of the relay station, and transmits a second message with the configuration pattern to the relay station. The configuration pattern is used to divide the radio resource unit of the wireless communication system into a first set and a second set. Therefore, the base station transmits a first signal to the relay station through the first set, and the relay station transfers a second signal with a user equipment through the second set.

Wireless communication apparatuses, header compression methods thereof, and header decompression method thereof are provided. The header compression method enables the transceiver to establish a tunnel for a user equipment, enables the processing unit to receive a first packet, enables the processing unit to generate a second packet comprising an outer header set and the first packet, enables the processing unit to replace the outer header set of the second packet with a replaced header, and enables the transceiver to transmit the second packet by the tunnel according to an identity recorded in the replaced header. The header decompression method decompresses the header compressed by the header compression method.

A relay station and a backhaul connection method thereof are provided. The relay station adopts an NAS mechanism. A wireless communication system comprises the relay station, a base station, and a core network. The relay station comprises a processing unit and a transceiver. The processing unit enters a first state of the NAS mechanism after the relay station creates a radio connection with the core network. The transceiver transmits a backhaul connection request to the base station after the relay station enters the first state. The processing unit then enters a second state of the NAS mechanism after the transmission of the backhaul connection request. The transceiver then receives a backhaul connection response from the base station after the transmission of the backhaul connection request. The processing unit then enters the first state after the receipt of the backhaul connection response.

摘要:
An IP packet (210) is retrieved having a header and a payload. The header of the IP packet is compressed. The payload is appended to the compressed header to create a compressed IP packet. A multi-protocol label switch (MPLS) virtual circuit is established through a plurality of IP routers terminating at a destination of the IP packet. The compressed IP packet is converted into a MPLS packet (230). The MPLS packet (230) is transmitted through the MPLS virtual circuit. The MPLS packet is re-converted into the compressed IP packet at the destination. The compressed IP packet is decompressed at the destination (170).
摘要:
A non-standardized private computer network (20) uses a tunnel engine (50, 58) to allow a computer (12-16) on one private computer network with non-standard address to communicate over a standardized carrier network (32) with a computer (22-26) on the same private computer network. The tunnel engine includes a local router (52) and rule check engine (54) in the private computer network and a remote router (56) in the standardized carrier network. The rule check engine performs rule checks to determine proper encapsulation and routing of the message. The message is encapsulated with a standardized address of endpoints of a tunnel through the carrier network corresponding to the desired destination. With a standardized address, the encapsulated message packet passes through the tunnel and arrives at the boundary of the destination private computer system. The encapsulation is removed and the message is routed to the destination computer.
摘要:
A femtocell Base Station (femto-BS), a network resource allocation method, and a non-transitory tangible machine-readable medium thereof are provided. There are a plurality of available network resource units. The femto-BS determines an expected value that is related to the available network resource units being used by the femto-BS and its neighboring femto-BSs without having interferences. The expected value is related to a number of the available network resource units and a number of the neighboring femto-BSs. Based on the expected value, the femto-BS calculates a plurality of strategy probability values that are related to different numbers of the available network resource units used by the femto-BS. The femto-BS calculates an assigned number according to the strategy probability values. Among the available network resource units, the femto-BS can use the assigned number of them.
