Mapping multiple services into a single radio bearer in lte and single tunnel gprs

Abstract

In a wireless communication system, a wireless transmit receive unit (WTRU) adapted to bundle a plurality of services into radio access bearer (RAB) in an uplink signal and unbundle a plurality of services from a RAB in a downlink signal. The WTRU is adapted to communicate with a plurality of services through a communications tunnel.

1 . A method, implemented by a management entity/user plane entity (MME/UPE), of providing multiple services to a wireless transmit/receive unit (WTRU), the method comprising:
 mapping an application point node (APN) to an application gateway (AGW);   updating packet data protocol (PDP) context information with the AGW;   inserting an AGW address in the PDP context of the MME/UPE;   sending a PDP address received from the AGW; and   activating a PDP context between the MME/UPE and the WTRU.   
     
     
         2 . The method of  claim 1 , further comprising:
 receiving and validating an attach request.   
     
     
         3 . The method of  claim 1 , further comprising:
 selecting the APN.   
     
     
         4 . The method of  claim 1 , further comprising:
 setting up a tunnel between the MME/UPE and the WTRU.   
     
     
         5 . The method of  claim 1 , further comprising receiving a PDP context response that includes any of: a PDP type, a PDP address, an APN list, a generalized packet radio service (GPRS) tunnel protocol (GTP) tunnel establish granted signal, or an AGW tunneling end-point identifier (TEID). 
     
     
         6 . A management entity/user plane entity (MME/UPE) configured to map an application point node (APN) to an application gateway (AGW), update packet data protocol (PDP) context information with the AGW, insert an AGW address in the PDP context of the MME/UPE, send a PDP address received from the AGW, and activate a PDP context between the MME/UPE and the WTRU. 
     
     
         7 . The MME/UPE further configured to receive and validate an attach request, select the APN and set up a tunnel between the MME/UPE and a wireless transmit/receive unit (WTRU). 
     
     
         8 . The MME/UPE of  claim 6  wherein a PDP context response includes any of: a PDP type, a PDP address, an APN list, a generalized packet radio service (GPRS) tunnel protocol (GTP) tunnel establish granted signal, or an AGW tunneling end-point identifier (TEID). 
     
     
         9 . A method, implemented by a gateway, of providing multiple services to a wireless transmit/receive unit (WTRU), the method comprising:
 mapping application point nodes to a plurality of services;   receiving the plurality of services over a tunnel using a multi-service bearer and a multi-service PDP context; and   distributing a service of the plurality of services to an application point node mapped to the respective service.   
     
     
         10 . A gateway configured to provide multiple services to a wireless transmit/receive unit (WTRU), comprising:
 a processor configured to map application point nodes to a plurality of services; and   a transmit/receive unit configured to receive the plurality of services over a tunnel using a multi-service bearer and a multi-service PDP context and distribute a service of the plurality of services to an application point node mapped to the respective service.
