Embodiment Construction

[0046] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] in such as figure 2 In the LTE standard Femto system architecture, it can be seen from the connection relationship of each network element that for MME, HeNB GW is equivalent to macro station eNB; for HeNB, HeNB GW is equivalent to MME, so whether HeNB directly communicates with MME / S-GW The connection, or the connection between the HeNB and the MME / S-GW through the HeNB GW, the definition and function of the S1 interface are completely consistent. In order to make the capacity of HeNB GW no longer limited by the number of TAC, CSG, and PLMN stipulated in the agreement, the present invention provides a method for expanding the capacity of the gateway HeNB GW in the LTE home base stati...

Abstract

The invention discloses a gateway capacity enlarging method in a long-term-evolution (LTE) femto and a gateway capacity enlarging apparatus in the long-term-evolution (LTE) femto. The gateway capacity enlarging method of the invention is different from a method in the prior art in which only one S1 link exists between a home?eNB?gateway (HeNB GW) and a mobility?management?entity (MME) in the long-term-evolution (LTE) femto in that a plurality of S1 links for signaling or data transmission are built between the home?eNB?gateway (HeNB GW) and the mobility?management?entity (MME), and therefore, the capacity of the home?eNB?gateway (HeNB GW) can be enlarged based on a used protocol, and networking requirements can be satisfied. According to the gateway capacity enlarging method and apparatus in the long-term-evolution (LTE) femto of the invention, the number of required S1 links is determined based on existing network planning as well as system real-time or periodic data statistics, and therefore, existing network use requirements can be satisfied, and system resources will not be wasted to establish free links; the S1 links are selected to be built on different stream?control?transmission?protocols (SCTP) or different streams loaded by the same stream?control?transmission?protocol (SCTP) according to the transmission capacity of a current stream?control?transmission?protocol (SCTP), and therefore, the capacity of the home?eNB?gateway (HeNB GW) can be further enlarged.
