Applicant elects without traverse the following: invention I including claims 1-7. Applicant withdraws claims 8-20 (cancelled). The Applicant presents new claims 21-32. claims 1-7 and 21-32 will be pending in this Application. Notice of Pre-AIA or AIA Status 3. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 112 4. The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. 5. Claim 1 and its dependent claims 2-7 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. For claim 1, it recites limitations of “a first subnetwork control plane (snCP) layer” in “performing, with a first subnetwork control plane (snCP) layer, control plane signaling with a second snCP layer, the second snCP layer associated with a node of a subnetwork that is coupled with a radio access network (RAN), wherein the subnetwork is managed by a management node (MN)”; However, it is not clear whether the “first subnetwork control plane (snCP) layer” is associated with a node of a subnetwork that is coupled with a radio access network (RAN) like the second snCP layer; or the “first subnetwork control plane (snCP) layer” is associated with something else; if the “first subnetwork control plane (snCP) layer” is associated with something else, then which one the first subnetwork control plane (snCP) layer is associated with? it recites limitations of “data” in “and processing, based on the control plane signaling, data received from the RAN or transmitted to the RAN”; However, it is not clear which one is the destination of “the data received from the RAN “ and which one is the sender of “the data transmitted to the RAN”; is it the node of a subnetwork that is coupled with a radio access network (RAN)? The MN? or something else ? Thus the scope of the claim and its dependent claim 2-7 are unclear. 6. Claim 21 and its dependent claims 22-27 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. For claim 21, it recites limitations of “a first subnetwork control plane (snCP) layer” in “perform, with a first subnetwork control plane (snCP) layer, control plane signaling with a second snCP layer using the interface circuitry, the second snCP layer associated with a node of a subnetwork that is coupled with a radio access network (RAN), wherein the subnetwork is managed by a management node (MN)”; However, it is not clear whether the “first subnetwork control plane (snCP) layer” is associated with a node of a subnetwork that is coupled with a radio access network (RAN) like the second snCP layer; or the “first subnetwork control plane (snCP) layer” is associated with something else; if the “first subnetwork control plane (snCP) layer” is associated with something else, then which one the first subnetwork control plane (snCP) layer is associated with? it recites limitations of “data” in “and process, based on the control plane signaling, data received from the RAN or transmitted to the RAN”; However, it is not clear which one is the destination of “the data received from the RAN “ and which one is the sender of “the data transmitted to the RAN”; is it the node of a subnetwork that is coupled with a radio access network (RAN)? The MN? or something else ? Thus the scope of the claim and its dependent claim 22-27 are unclear. 7. Claim 28 and its dependent claims 29-32 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. For claim 28, it recites limitations of “data” in “and processing, based on the control plane signaling, data received from the RAN or transmitted to the RAN”; However, it is not clear whether which one is the destination of “the data received from the RAN “ and which one is the sender of “the data transmitted to the RAN”; is it the UE? The MN or something else ? Thus the scope of the claim and its dependent claim 29-32 are unclear. 8. Claim 2 and its dependent claim 3 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. For claim 2, it recites limitations of “the node” in “wherein the node is the MN”; However, it is not clear whether “the node” refer to “a node of a subnetwork that is coupled with a radio access network (RAN)” or “a management node (MN)” in “wherein the subnetwork is managed by a management node (MN)” recited in independent claim 1. Thus the scope of the claim and its dependent claim 3 are unclear. 9.. Claim 4 and its dependent claim 5-6 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. For claim 4, it recites limitations of “the node” in “offloading a sublayer of a network control plane (nwCP) layer to the node”; However, it is not clear whether “the node” refer to “a node of a subnetwork that is coupled with a radio access network (RAN)” or “a management node (MN)” in “wherein the subnetwork is managed by a management node (MN)” recited in independent claim 1. Thus the scope of the claim and its dependent claim 5-6 are unclear. Claim Rejections - 35 USC § 102 10. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
