Method and apparatus for communicating short message service and supplementary services messages

摘要

Methods and apparatus for enabling short message service (SMS) and supplementary services (SS) in a long term evolution (LTE) network via evolved packet system (EPS) mobility management (EMM) over the LTE control plane are described. In one embodiment, the radio resource control (RRC) connection signaling radio bearer (SRB) is used for SMS and SS transport over the LTE control plane between a wireless transmit/receive unit (WTRU) and a mobility management entity (MME). EMM interfaces and primitives are defined for actions towards SMS and SS entities for enabling SMS and SS services in LTE via the LTE control plane media. Message formats for SMS and SS message transport are also disclosed for sending SMS and SS messages within EMM uplink (UL) non-access stratum (NAS) transport and downlink (DL) NAS transport messages.

主权项

1. A wireless transmit/receive unit (WTRU) comprising:
a processor configured to produce a service message; the processor further configured to encapsulate the service message into an uplink (UL) non-access stratum (NAS) transport message, wherein the UL NAS transport message includes a protocol discriminator field, a NAS message container that includes the service message, a message type field of the UL NAS transport message, and a message type field of the service message, wherein the NAS message container includes the service message; the processor further configured to produce a RRC UL information transfer message including the UL NAS transport message; and the processor further configured to transmit the RRC UL information transfer message over a signaling radio bearer (SRB).
