METHOD FOR ENHANCED ACCESS SELECTION FOR A USER EQUIPMENT IN A CELLULAR TELECOMMUNICATIONS NETWORK, TELECOMMUNICATIONS NETWORK, AND SYSTEM FOR ENHANCED ACCESS SELECTION OF A USER EQUIPMENT

摘要

A method for enhanced access selection for a user equipment in a cellular telecommunications network includes: in a first step, a serving base station entity sending validation information to the user equipment, the validation information having either a positive value, indicating to apply a policy corresponding to a policy information data element, or a negative value, indicating not to apply the policy corresponding to the policy information data element; and in a second step, subsequent to the first step, the user equipment applying the policy corresponding to the policy information data element in case that the validation information has a positive value, and the user equipment terminating the data bearer or refraining from establishing the data hearer via the access point in case that the validation information has a negative value.

1. A method for enhanced access selection of for a user equipment in a cellular telecommunications network;
wherein the cellular telecommunications network comprises an access network; wherein the user equipment is located in a radio cell of the access network and in a radio coverage area of an access point, wherein the radio cell is served by a serving base station entity, wherein the user equipment is registered with the telecommunications network via the serving base station entity, wherein the user equipment comprises or receives a policy information data element, the policy information data element being related to a policy regarding establishment of a data connection, using at least one data bearer, of the user equipment with the telecommunications network, via the access point instead of via the serving base station entity, wherein in case that a data bearer between the user equipment and the telecommunications network is to be established or is ongoing, and the policy allows the establishment or continuation of the data bearer of the user equipment via the access point instead of via the serving base station entity, the method comprises the following steps: in a first step, the serving base station entity sending validation information to the user equipment, the validation information having either a positive value, indicating to apply the policy corresponding to the policy information data element, or a negative value, indicating not to apply the policy corresponding to the policy information data element; and in a second step, subsequent to the first step, the user equipment applying the policy corresponding to the policy information data element in case that the validation information has a positive value, and the user equipment terminating the data bearer or refraining from establishing the data bearer via the access point in case that the validation information has a negative value.
