Abstract: A method of provisioning multicast services is provided. In an example, the method includes forming a plurality of multicast groups, each of the plurality of multicast groups associated with one of a plurality of first channel quality ranges. A request for a multicast service and an indicator (e.g., a channel quality indicator (CQI)) indicating a channel quality of a mobile unit are received from the mobile unit. The mobile unit is assigned to one of the plurality of multicast groups based on the indicated channel quality and the plurality of first channel quality ranges.

Abstract: Not Mobile IP (NMIP) comprises methods for implementing macro-mobility in an IP network, wherein macro-mobility means the ability of a node to change its network-layer, e.g., IP, address without disturbing existing transport-layer and application-layer sessions, e.g., conversations. When two NMIP nodes establish a new NMIP session, they exchange pseudo-random numbers, or nonces, and store the nonces in a session table. When a first node changes its IP address, the first node sends to the second node an address-update message that contains the new IP address and the first node's nonce. If the received nonce matches a nonce in the session table, then the second node updates its protocol control blocks with the new IP address, and sends an address-update reply message to the first node. Internet Protocol Security (IPsec) can be used to secure or replace the exchange of nonces.

Abstract: A method and an apparatus are provided for enabling a wireless communication over a network in response to an indication of an emergency. The method comprises causing a base station to provide a wireless backhaul link in an uplink frequency band for further sending a call over the network in response to the call associated with the emergency. Reconfiguration enables turning a base station or base station router into a high power terminal. In this way, emergency calls may be completed over a network having at least one malfunctioning backhaul communications link in a network backbone.

Abstract: In a wireless data network, such as a General Packet Radio Service (GPRS) network, a transmitter uses one of k coding/modulation schemes for transmitting data. The transmitter initially selects a coding/modulation scheme, C, as a function of carrier-to-interference ratio (C/I) measurements. The transmitter then calculates the number of blocks, B, required to transmit a number of data packets, D, using the coding/modulation scheme C. In addition, the transmitter calculates the number of blocks required to transmit the number of data packets, D, for each coding/modulation scheme that is stronger than the selected coding/modulation scheme C. The transmitter finally selects that coding/modulation scheme that results in transmitting the number of data packets D in B blocks using the strongest coding/modulation scheme. As a result, each block is transmitted using the strongest coding/modulation scheme available.

Abstract: Not Mobile IP (NMIP) comprises methods for implementing macro-mobility in an IP network, wherein macro-mobility means the ability of an endpoint node to change its network-layer, e.g., IP, address without disturbing existing transport-layer and application-layer sessions, e.g., conversations. When two NMIP endpoint nodes establish a new NMIP session, they exchange pseudo-random numbers, or nonces, and store the nonces in a session table. When a first endpoint node changes its IP address, the first endpoint node sends to the second endpoint node an address-update message that contains the new IP address and the first endpoint node's nonce. If the received nonce matches a nonce in the session table, then the second endpoint node updates its protocol control blocks with the new IP address, and sends an address-update reply message to the first endpoint node. Internet Protocol Security (IPsec) can be used to secure or replace the exchange of nonces.
