Embodiment Construction

[0091] The non-limiting embodiments of the present invention relate at least in part to E-UTRAN. E-UTRAN provides a new protocol architecture, which intends to efficiently serve services in the packet switched (PS) domain. The IP protocol is used for transmission in the RAN and on the air interface.

[0092] The use of non-limiting embodiments of the present invention provides low control plane settings and user service delays, provides good support for Internet protocol-based packet switching services, and avoids delays caused by traditional hierarchical carrier negotiation between several network elements .

[0093] Because RRC is completely configured in the BS, the protocol structure avoids the traditional bearer negotiation between several network elements. In the BS, IP flows can be used for IPCS, and IPCS allows user plane service flows to interact with MAC locally.

[0094] The exemplary embodiments of the invention described in the combined application relate at least in ...

Abstract

A series of logical channel identifiers LCIDs, each associated with one radio link service profile RLSP, is stored in a local memory. The local memory is accessed whenever a LCID is taken into use for identifying an active logical channel, and each RLSP includes a set of radio link service parameters at least one of which is a quality of service parameter. A first data packet bearing a LCID and establishing a flow is received over a wireless logical channel. The local memory is accessed to determine if an RLSP is associated with the LCID of the first data packet. For the case where an RLSP is not associated with the LCID in the local memory, the LCID is associated with a designated default RLSP, and the first data packet is processed using the designated default RLSP. Predetermined and custom RLSPs are also described, as are methods, devices, programs, an integrated circuits embodying the invention.
