摘要： A method of determining a radio link failure associated with a handover of a user equipment from a source access node to a target access node includes acquiring a first information about a time associated with the user equipment communicating with an access node for establishing a connection associated with the handover and a second information indicating the access node with which the user equipment communicates for establishing a connection subsequent to the radio link failure, and determining the radio link failure based on the acquired first and/or second information.

摘要： Systems and techniques for avoiding inefficiencies resulting from failed handover attempts. A base station selects one or more mobility management entity (MME) pools for assignment to a relay node, with the selection being performed so as to minimize or eliminate handover attempts requiring that a target device support a particular MME pool when the MME pool is not supported by the MME. A base station selects, when communicating with a relay node, a subset of the MME pools that it supports and assigns the subset to the base station. UEs served by the relay node are assigned the MME pool or MME pools assigned to the relay node. The relay node is informed of the MME pools supported by one or more neighbor nodes and, when attempting a handover to a neighbor node, attempts an X2 handover only to neighbor nodes supporting an MME pool assigned to the relay node.

摘要： According to one general aspect, a method may include transmitting, from a first network entity to a peer network entity, an offer to perform at least one networking function, wherein the offer includes a set of parameters indicating at least one networking capability that may be employed by the first network entity to perform the networking function. The method may include receiving, from the peer network entity, a set of parameters indicating at least one networking capability that may be employed by the peer network entity to perform the networking function. The method may include determining if at least one networking capability may be employed by both the first network entity and peer network entity to perform the networking function. The method may include selecting at least one networking capability to employ to perform the networking function. The method may include other actions as described herein.

摘要： An interference control method and apparatus in a self-organizing system are provided. The method includes the following steps: interference information is received at an access node from at least two other access nodes, wherein the other access nodes serve communication devices interfered by the access node; then the interference information is evaluated at the access node to determine at least one action that could be taken because of the interference; information about the determined at least one action is communicated to at least one of the at least two other access nodes, and the recipient node is operated accordingly.
