The invention relates to a node in a communications network for enabling communication with at least one wireless communication terminal served by the communications network. According to an embodiment, the node stores at least one current User Equipment (UE) context of the at least one communication terminal to be used by a first network entity of the plurality of network entities in the communications network; receives, from a second network entity of the plurality of network entities, a message intended for the first network entity; and delivers at least a part of the received message to the first network entity and at least a part of the stored at least one current UE context to be used by the first network entity.

Central node management of UE context

A mobility management node (e.g., MME) for selecting a network access gateway node (e.g., PGW) when establishing a PDN connection for a radio terminal to a PDN identified by an APN, which mobility management node is configured to operatively manage the mobility for the radio terminal and which access gateway node is configured to operatively act as a network access gateway to the PDN so as to provide connectivity for the radio terminal to the PDN.

Gateway weight factor and load information

The disclosure herein is directed to a method in a mobility management node (MME) and a mobility management node (MME) for executing the method of selecting a network access gateway node (PGW, PGW, PGW) when establishing a PDN connection for a radio terminal (UE) to a PDN () identified by an APN (APN) which mobility management node is configured to operatively manage the mobility for the radio terminal and which access gateway node is configured to operatively act as a network access gateway to the PDN so as to provide connectivity for the radio terminal to the PDN, the method comprises: receiving (), from a number of network access gateway nodes (PGW, PGW, PGW), APN capacity allocation information indicating the APN capacity that each access gateway node has allocated to serve the APN, and APN load information indicating the APN load that each access gateway currently experience with respect to the APN, receiving (), from a Domain Name Server (DNS), weight factor information indicating the relative amount at which each access gateway node should be selected when a PDN connection is created, and selecting () a network access gateway node among said number of network access gateways based on the APN capacity allocation information and the APN load information and the weight factor information.

The present invention relates to a solution for paging of idle user equipment and in particular for changing mode status from idle to connected in an efficient manner. This is provided in a method, nodes, and a system arranged to determine a suitable paging message related to a framework table indicating selection criteria entries for access point name, quality of service class indicator, IMSI number, and IMEI number and determining from the framework table a paging granularity set to be used in the paging request from a granularity table comprising entries for paging areas, number of paging retries, and time between retransmissions.

Solution for paging differentiation in communication network

A method in a server for controlling the distribution of messages from a plurality of clients among a plurality of processing means, including the steps of: establishing whether a message received on an interface board of the server is addressed using a normal identity specific for the client that sent the message and, if yes, then: using a first algorithm to map the normal identity to a load index in a first mapping means; and, mapping the load index to one of the plurality of processing means using a mapping table provided in the interface board. If the message is addressed using an internal identity generated in the server, rather than the normal identity specific for the client that sent the message, then: using a second algorithm to map the internal identity to a load index in a second mapping means; and, mapping the load index to one of the plurality of processing means using the mapping table provided in the interface board.
