摘要:
The present disclosure relates to devices and methods for establishing and maintaining backhaul connections between small cell radio base stations and a core network. In particular it relates to methods using a client to manage the backhaul connection. According to one aspect, the method relates to receiving, from the small cell RBS, at least one message triggering the establishment of the wireless backhaul connection between the small cell RBS and the core network. The method further comprises deriving, from the at least one message, base station property information of the small cell RBS. The method further comprises sending, to a core network node, a connectivity request message, including the derived base station property information thereby enabling a selection of a packet gateway and/or a configuration for the small cell RBS in the establishment of the wireless backhaul connection. The disclosure also relates to a method performed in a core network node and to a corresponding client and core network node.

An LTE network (100, 300, 400) having a plurality of base stations (110, 320, 420) and S-GWs (120, 340, 440) processes GTP packets to determine an amount of GTP tunnels (140, 382, 491-492) between the base stations (110, 320, 420) and the S-GWs (120, 340, 440). The LTE network (100, 300, 400) processes the amount of GTP tunnels (140, 382, 491-492) to determine a target amount of LTE P-GWs (130, 350, 450) to serve the base stations (110, 320, 420). If the target amount of the LTE P-GWs (130, 350, 450) is greater than a current amount of the LTE P-GWs (130, 350, 450), then an additional amount of virtual LTE P-GWs (130, 350, 450) is implemented to serve the base stations (110, 320, 420). If the target amount of the LTE P-GWs (130, 350, 450) is less than the current amount of the LTE P-GWs (130, 350 450) then an amount of the virtual LTE P-GWs (130, 350, 450) that serve the base stations (110, 320, 420) are removed.

The present disclosure relates to methods, radio access nodes and computer-readable storage media for secure connection set up between a first and a second access node of a wireless network. The method of establishing a secure connection from a first access node (eNB A) to a second access node (eNB B), comprises transmitting (S1a) a connection termination end point request from the first access node(eNB A)and receiving (S2a) a response comprising a set of secure connection termination end points for the second access node(eNB B). One or more secure connections are established (S3a) to the second access node(eNB B), wherein each secure connection includes a secure connection link from the first access node (eNB A) to a termination end point selected from the set of secure connection termination end points. The method performed in the second access node (eNB B) comprises receiving (S1b) a connection termination end point request and transmitting (S2b) a response comprising a set of secure connection termination end points for the second access node (eNB B) to the first access node (eNB A). The method also comprises providing a secure connection from the second access node (eNB B) to each termination end point in the set of secure connection termination end points.

摘要:
A communication system is described. The system includes: at least one gateway able to provide broadband connectivity, a set of ground terminals, and a set of high altitude platforms (HAPs), where at least one aerial platform is able to communicate with at least one gateway using radio frequencies, each HAP is able to communicate with ground terminals using radio frequencies, and each HAP is able to communicate with each other HAP using radio frequencies. Ways to handoff a ground terminal/gateway from one HAP beam to another HAP beam are described. Ways to handoff a ground terminal/gateway from one HAP to another HAP are described. Ways that keep the communications payload radios active when there is data traffic and put the radios in sleep mode otherwise, thereby adjusting the communications payload power consumption to the data traffic requirements as a function of time and coverage area, are described.
