AI Technical Summary

Problems solved by technology

However, this will result in additional signaling that does not improve the user experience
Furthermore, when the UE is connected to the second core network node, it may be determined that the second core network node is also experiencing overload, so the second base station may have to request the UE to enter idle mode and send a connection request to the third base station, etc.
This will result in more additional signaling which further deteriorates the user experience

Embodiment Construction

[0037]As part of developing the examples herein, some problems with prior art communication systems will first be identified and discussed.

[0038] Today, when an eNB such as a RNN receives an RRC Connection Request (RRCConnectionRequest) message, it is not possible to know the selected Public Land Mobile Network Identity (PLMN ID) of a UE such as a wireless device. This information is crucial to be able to understand which PLMN the UE is trying to connect to. For example, this information will indicate which shared operator in a shared RAN / CN deployment the UE is trying to connect to. This information is only known after the RRC connection request has been positively acknowledged by means of an RRCConnectionSetup message. That is, only when the RRCConnectionSetupComplete message is received (which indicates the completion of the RRC connection and the UE can no longer be rejected at this point in time), the selected PLMN ID is useful for e.g. the sharing in RAN / CN sharing d...

Abstract

A shared Radio Network Node, RNN, (102) and a method therein for managing overload in at least one core network (110) are provided. The shared RNN is configured to serve a wireless device (104). The wireless device and the shared RNN are operated in a wireless communications network (105) connected to the at least one core network. The shared RNN receives a connection request from the wireless device. The connection request comprises a mapping parameter configured to map to a Mobility Management Entity, MME, (112) comprised in the at least one core network and connected to the shared RNN. The mapping parameter comprises an MME Code, MMEC, which is uniquely assigned to the MME and to a sharing operator. Further, the shared RNN rejects or redirects the connection request when the MME is overloaded.

Description

technical field [0001] Embodiments herein relate generally to wireless devices, shared radio network nodes and methods therein. In particular, they relate to the management of overload in at least one core network. Background technique [0002] A communication device such as a terminal or a wireless device is also referred to as eg user equipment (UE), mobile terminal, station (STA), wireless terminal and / or mobile station. Such terminals are capable of communicating wirelessly in a wireless communication network or cellular communication system (sometimes also referred to as a cellular radio system or cellular network). The communication may be, for example, between two terminals, between a terminal and a conventional telephone, and / or between a terminal and a server via a radio access network (RAN) comprised within a cellular communication network and possibly one or more core network to perform. [0003] The aforementioned terminal or wireless device may also be called...
