摘要:
In communications networks, network elements require knowledge of other network elements such as when they are added to or deleted from the network configuration and the resources they have available. The protocol allows network elements to communicate resource information dynamically and directly. The protocol also allows direct exchange of network configuration information between network elements for determining wireless communications network paging areas.

A cryptosync design comprising (1) a channel identifier indicative of a particular channel via which a data packet is sent, (2) an extended time stamp indicative of a time value associated with the data packet, and (3) a counter indicative of a packet count associated with the data packet. The lengths of the extended time stamp and counter fields and the time unit for the extended time stamp are parameters that may be configured for each channel. At the sender, the extended time stamp for the cryptosync may be obtained from the System Time maintained by the sender. The counter value for the cryptosync may be provided by a counter that is maintained for the channel by the sender. The sender may include a time stamp and/or the counter value, if they are needed to derive the cryptosync at the receiver, in a header of the data packet.
摘要:
Techniques for efficient storage and retrieval of Preferred Roaming Lists are disclosed. In one aspect, PRL entries are stored in two tables. One table contains records that are common to two or more PRL entries. Another table stores any information that is unique to a PRL entry, as well as an indicator of which common record is associated with it. The common record is concatenated with the unique information to generate the uncompressed PRL entry. Various other aspects of the invention are also presented. These aspects have the benefit of reducing the memory requirements for storing a PRL. In addition, time required to download the compressed PRL is reduced.
摘要:
Methods and apparatus for tunneling packets between remote and serving Access points for delivery to an access terminal (AT) are described. Methods and apparatus for communicating control values and/or information in addition to information to be delivered to an AT over an airlink are also described. An AT uses the received control information to recover communicated packets. Some features support the use of various headers and/or indicators in the headers, e.g., RLP and/or Packet Correlation Protocol (PCP) headers, which may be used to control routing of communicated payloads to an RLP processing module corresponding to an AP which was the source of the communicated payload.

Operating a communication device in a half-duplex mode using only overhead channels; and substantially free running a timing reference obtained during reception to allow a timing reference value to drift during transmission.
摘要:
Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve monitoring a first network in accordance with a first air interface, and receiving a message from a second network through the first air interface, the second network being associated with a second air interface different from the first air interface. Various registration and related techniques are also discussed for maintaining connectivity with both networks as the wireless communications device moves through different geographic coverage regions.
摘要:
The present apparatus comprises a radio access network element having at least one processor, and at least one memory operably connected to the at least one processor, whereby the radio access network element is adapted to execute instructions stored in the memory comprising discovery of at least one other element in a radio access network. The radio access element further comprises instructions for removal or addition of network elements, instructions for determining a paging area and instructions for forwarding messages from a mobile to a controller in another domain.

A method and a system for providing signaling in cellular telephone system providing broadcast services to fully integrate broadcast services with the services provided by the cellular telephone systems. The signaling method coordinate interaction between an access network and the subscriber station to allowing the subscriber station to decode the broadcast service, to receive paging messages while receiving the broadcast service, to properly transition between operation states, and other functions known to one of ordinary skill in the art.

摘要:
Methods and apparatus for communicating between an access terminal (AT) and a device serving the AT by way of an Access Point (AP) are described. In accordance with one feature serving devices may be assigned specific addresses which are interpreted based on the source of the communication, e.g., MAC packet, in which the address is used. Such addresses may be interpreted as being of a different type than other addresses which can be interpreted and/or used without taking into account the identity of the sender. In some embodiments Session Controllers and/or Internet Attachment Points (IAPs) are identified with such addresses. The address value is the same for one or more ATs but is interpreted at an AP receiving such the IAP address based on information corresponding to the AT which sent the packet including the IAP or Session Controller address.
