    摘要: A network function is configured to maintain a copy of a session state for an access terminal. The network function is further configured to query a session master to determine whether the session state has changed. The session master is configured to generate a response to the query that enables the network function to update the copy of the session state if the session state has changed. The access terminal may be configured to change the session state at a first network function and send a message to a second network function to indicate that the session state has been changed.

    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.

    摘要: 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.
