    摘要： Methods, apparatus, systems, architectures and interfaces for a wireless transmit receive unit (WTRU) performing a client-side edge resolution function (cERF) are provided. A method may include any of: transmitting, to a network-side edge application resolver (nEAR), a signal requesting an IP address identifying (e.g., associated with) a domain name system (DNS) server associated with the WTRU; applying, by the WTRU, any of edge instance (EI) record rules for the identified DNS server, or updating EI records with the IP address identifying the DNS server; transmitting, to a DNS server, a DNS query associated with a fully qualified domain name (FQDN); receiving, in response to the DNS query, FQDN resolution from the DNS server; on condition that a mobility event of the WTRU occurs, transmitting, to the nEAR, a signal requesting information for updating the EI records of the WTRU; and applying, by the WTRU, any of the updated EI record rules in order to perform any of: (1) redirecting application session traffic to provides session continuity for the WTRU, and (2) breaking any number of application sessions.

    摘要： Methods, apparatus, systems, architectures and interfaces for a wireless transmit receive unit (WTRU) performing a client-side edge resolution function (cERF) are provided. A method may include any of: determining a fully qualified domain name (FQDN) associated with a domain name server (DNS) request of an application associated with the WTRU; if the FQDN is associated with a valid edge instance (EI) record, selecting an EI for resolving the FQDN to an IP address; if the FQDN is not associated with a valid EI record: (1) transmitting a DNS query to a DNS server, (2) receiving an IP address associated with a selected EI to which the FQDN is resolved, and (3) updating the EI record with the IP address and the FQDN; and generating a traffic steering rule to re-direct uplink traffic associated with the application to the selected EI.

    摘要： Systems and methods for using a communication system in a spectrum are provided. For example, a random access or RACH procedure may be performed where the random access or RACH procedure may be configured to reduce secondary interference and/or to be used in a pixel-based environment. The random access or RACH procedure may include selecting a RACH preamble; sending a RACH preamble and/or format information; determining a transmission power of the RACH preamble and/or the format information; determining a random access radio network temporary identifier (RA-RNTI) and preamble ID associated with the RACH preamble; and/or selecting a physical RACH (PRACH).

    摘要： A method and apparatus are described for synchronizing mobile station (i.e., wireless transmit/receive unit (WTRU)) media flows during a collaboration session. Inter-WTRU transfer request messages, flow addition request messages and session update request messages may be exchanged between a plurality of WTRUs and a session continuity control application server (SCC-AS). Each of the messages may include a session description protocol (SDP) attribute line containing time synchronization information (e.g., a presentation time offset (PTO) information element (IE), a media flow group identity (ID) and a synchronization tolerance IE). The SCC-AS may update the time synchronization information and include the updated information in messages it sends to the WTRUs, which may re-synchronize their respective media flows based on the updated time synchronization information.

    摘要： Methods and apparatus are provided for performing group-based machine-to-machine communication. Machine-type communication (MTC) wireless transmit/receive units (WTRUs) may operate in MTC groups. MTC WTRUs belonging to the same MTC group may use a group-based International Mobile Subscriber Identity (IMSI) and a group-based IP address for data transmission. Group-based network registration may be performed. A group-based IP address and radio resources may be proactively allocated for an MTC group. A master MTC may perform network registration/attachment process on behalf of the MTC group. A group of MTC WTRUs may transmit data according to staggered time windows.

    摘要： A wireless transmit / receive unit, WTRU, connects to a first AP, receives domain identifiers, requests corresponding descriptors and receives a list of descriptors. An application on the WTRU requests a list of domains and attributes corresponding to service names or service sets, which is returned by the WTRU. The application selects one or more domains for communications, the WTRU selects corresponding network resources and the application connects to local services. After moving to a new location, the WTRU connects to a second AP and receives a second set of domain identifiers, selects the one matching the request from the application and provides these to the application that, with the aid of the WTRU connects to local services.
