摘要:
The invention relates to a method for use in a core network node, such as a mobility management entity, in a wireless communication network for associating a tracking area identity list comprising at least one tracking area identity (TAI) with a user equipment. The method comprises the steps of: associating a first tracking area identity list with a user equipment as the user equipment registers with the core network node; sending the first tracking area identity list to the user equipment; and receiving at least one tracking area identity comprising the tracking area identity of a tracking area being used by the user equipment. The method further comprising the steps of: compiling an second tracking area identity list based on the tracking area identity list currently associated with the user equipment and on the received at least one tracking area identity;in case the second tracking area identity list contains a different set of tracking area identities than the tracking area identity list currently associated with the user equipment, sending the second tracking area identity list to the user equipment to replace an earlier tracking area identity list in the user equipment; and associating the second tracking area identity list with the user equipment in place of the tracking area identity list currently associated with the user equipment. The invention further relates to a core network node, such as a mobility management entity, and a computer program product for use in such a core network node.
摘要:
A method of allocating user plane nodes to a connection being established across a packet core network. The method comprises maintaining at a Domain Name System, DNS, server, one or more DNS resource records for each available user plane node or group of neighboring user plane nodes, a DNS resource record containing a measure of a route quality or cost between the associated user plane node(s) or group(s) and each of one or more further user plane nodes or further groups of neighboring user plane nodes of the packet core network to which said associated user plane node(s) or groups is(are) connected. A connection establishment request is processed at a mobility management control entity within the packet core network, with a DNS query being sent to a DNS server, the query containing one or more user plane node selection criteria. The query is received at the DNS server and, on the basis of the or each criterion, one or more DNS resource records satisfying the criteria/criterion identified. At least said measure of route quality or cost of the identified DNS resource record(s) is returned to said mobility management control entity. The measure(s) of route quality or cost of the identified DNS resource record(s) is received at the mobility management control entity, and the measure(s) used to allocate a user plane node or nodes to said connection.
摘要:
A method for use in a core network node, such as a mobility management entity, is described for associating a tracking area list comprising at least one tracking area identity (TAIs) with a user equipment. A wireless communication network, such as an EPS network, comprises the core network node. The method comprises the steps of: registering at least one tracking area identity sequence of tracking areas repetitively used by a plurality of user equipments; and compiling at least one tracking area list using the at least one registered tracking area identity sequence. The disclosure also relates to a core network node and a computer program product.
