GTP handover group

GTP handover group configuration is supported on GTP profiles. An administrator can configure a GTP profile and associate a GTP handover group to a GTP profile. A GTP handover group is a set of SGSNs or serving gateway (SGW) with a common address-book library. When a GTP handover group name is referenced by a GTP profile, the device checks to see if the current SGSN/SGW address and the proposed SGSN/SGW address are contained within the same GTP handover group. If both the current and proposed SGSN/SGW addresses are contained within the same GTP handover group, then the handover is allowed. If both the current and proposed SGSN/SGW addresses are not within the same GTP handover group, then the profile for the default handover group is used. This feature enables the administrator to define policies that determine whether handover can happen between individual SGSNs/SGW and/or groups of SGSNs/SGW for roaming.
