Title:
SUBSCRIPTION INFORMATION UPDATE METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/158049
Kind Code:
A1
Abstract:
The present invention provides a subscription information update method and apparatus. The method comprises: after a second NF forwards first subscription information to a third NF, wherein the first subscription information comprises a first correlation identifier allocated by the second NF for a first NF, the third NF allocates a second correlation identifier for the first NF and receives a subscription update message of the first NF, wherein the subscription update message comprises the second correlation identifier. Use of the present solution resolves the lack in the prior art of a subscription information update scheme adaptable to new systems. With the proposed subscription information update scheme adaptable to new systems, in a case where cross-NF registration occurs in a user terminal, for example, a subscription message between a new third NF and a first NF is updated in a timely manner.
