Abstract: A first communication node communicates by multiple-input-multiple-output (MIMO) wireless communications with a second communication node of a wireless communication system. The method includes receiving a Sounding Reference Signal (SRS) over a plurality of subcarriers transmitted by the second communication node for MIMO communications. Channel quality is measured responsive to the sounding reference signal to output a first channel quality value. A demodulation reference signal is received over a plurality of subcarriers transmitted by the second communication node for MIMO communications. Channel quality is measured responsive to the demodulation reference signal to output a second channel quality value. Reliability of the measurements of the first channel quality value and the second channel quality value is determined. The first and second channel quality values are combined while compensating for the determined reliability difference between the measurements to generate a combined channel quality value.

Abstract: A method and apparatus for providing both Mobile Terminated, MT, and Mobile Originated, MO, circuit switched (CS) services such as Short Message Service, SMS, services in networks utilizing CS Fallback and CSoLTE-I architectures. An extended SGs interface referred to as SGs+ is implemented between a Mobility Management Entity, MME, in an SAE core network and a Mobile Switching Center Server, MSC-S. The SGs+ interface supports transmission of upper layer CS packet data units while utilizing either connectionless or connection-oriented Signaling Connection Control Part, SCCP, operation. The non access stratum, NAS, signaling support between the User Equipment, UE, and the MME is extended to provide support for both MT SMS and MO SMS service.

Abstract: A system that provides services to clients may receive and service requests, various ones of which may require different amounts of work. An admission control mechanism may manage requests based on tokens, each of which represents a fixed amount of work. The tokens may be added to a token bucket at rate that is dependent on a target work throughput rate while the number of tokens in the bucket does not exceed its maximum capacity. If at least a pre-determined minimum number of tokens is present in the bucket when a service request is received, it may be serviced. Servicing a request may include deducting an initial number of tokens from the bucket, determining that the amount of work performed in servicing the request is different than that represented by the initially deducted tokens, and deducting additional tokens from or replacing tokens in the bucket to reflect the difference.

Various methods for activating and deactivating the additional component carrier are also described.

Abstract: Disclosed herein are methods and systems for implementing dynamic modulation schemes based on paging area. In one embodiment, a radio access network (RAN) receives a request to page a user equipment (UE), and identifies the cell in which the UE was last registered. The RAN sends one or more paging requests in one or more cells, where the respective modulation coding scheme (MCS) that the RAN selects for each such paging request depends at least in part on the distance of the receiving cell from the cell in which the UE was last registered.

Abstract: Re-assigning Serving Call Session Control Function, S-CSCF, services to a user of a Home Subscriber Server, HSS (200), in a Third Generation Partnership Program, 3GPP, telecommunications network is provided. In the case that S-CSCF services to the user including a registration procedure are previously assigned and access by the user to the S-CSCF services is erroneously lost, the proposal is to provide a method and means to re-assign those services. First, dynamic registration information (204) is uploaded from S-CSCF to the HSS (200) during the registration procedure. Then, the dynamic registration information (204) is stored from HSS (200) to S-CSCF (203) during a re-assignment procedure of the user.

Abstract: The present invention is a method and system adapted to facilitate, between a mobile station (MS) and network, an indication of support for reduced time transmission interval (RTTI). The MS can provide a base station system (BSS) with an indication of its multislot capability within an access burst sent at the start of a contention based access. In another aspect, the MS can indicate support for a new Immediate Assignment message as the conventional Immediate Assignment message can only assign single timeslots. The present invention enables the Radio Access Network (RAN) to assign RTTI and more than one timeslot for GPRS/EDGE temporary block flows (TBFs) during an Access Grant Channel (AGCH) assignment. The method of the present invention can be implemented in a computer program product or distributed software adapted to be loaded into at least one or a plurality of memory locations and executed by at least one or a plurality of respective computer processors.

In this way, a VN port of an ENode may establish a virtual link with a VFC port that belongs to the same virtual network in preference, so that some ENodes are made to access FCFs that belong to the same virtual networks as the ENodes.
