5.7.2 General requirements

22.2203GPPRelease 17Service requirements for Home Node B (HNB) and Home eNode B (HeNB)TS

A H(e)NB subsystem shall be able to support Local IP Access in order to provide access for IP capable UEs connected via a H(e)NB subsystem (i.e. using H(e)NB radio access) to other IP capable entities in the same residential/enterprise IP network.

– Simultaneous access from a UE to the mobile operator’s core network (e.g. internet, PLMN services) and Local IP Access to a residential/enterprise IP network shall be supported.

– Subject to regulatory requirements, Local IP Access traffic shall be routable only between the UE, H(e)NB and other entities within the residential/enterprise IP network.

– A UE shall have a valid subscription with the mobile operator in order to use Local IP Access.

– A UE shall be able to use Local IP Access in a visited network subject to roaming agreement between mobile operators.

– The HPLMN shall be able to enable/disable LIPA usage when the UE roams to particular VPLMNs.

– Local IP Access shall not affect services running in parallel for the same UE.

– Pre-Rel 10 UEs should be able to use Local IP Access.

– The user may be notified when a H(e)NB provides access to a residential/enterprise IP network

– A UE using Local IP Access shall be contactable by another IP endpoint in the same residential/enterprise IP network via Local IP Access.

– The operator shall be able to configure the network to support connection request from a UE so that a LIPA connection is used when the UE is located within the residential/enterprise IP network, and a regular connection via the Core Network is used otherwise.

– It shall be possible for a UE to maintain its IP connectivity to the residential/enterprise IP network when moving between H(e)NBs within the same residential/enterprise IP network. Any interruption to this IP connectivity shall be limited to levels comparable to that of the IP connectivity for PLMN services.

NOTE: Loss of access to the residential/enterprise IP network is acceptable as a UE moves out of H(e)NB coverage.

– The mobile operator shall be able to configure the H(e)NB to enable/disable Local IP Access.

– The mobile operator shall be able to enable/disable Local IP Access per user subscription per CSG.

– The H(e)NB Hosting Party, within the limits set by the mobile operator, shall be able enable/disable Local IP Access per H(e)NB.

– The H(e)NB subsystem shall allow the mobile operator to make traffic and signalling performance measurements related to Local IP Access for each user and for the H(e)NB.

– The H(e)NB subsystem shall allow the mobile operator to collect fault management information related to Local IP Access for each H(e)NB.

NOTE: It is possible for the H(e)NB Hosting Party to use additional access control mechanisms (e.g. using a password) to restrict access of UEs to the residential/corporate IP network. However, such additional access control is out of scope of 3GPP standardisation.

– Local IP Access shall not compromise the security of the mobile operator’s network.
